     NOW, THEREFORE, the parties hereto hereby agree as follows:

SECTION 1.  Authorization and Sale of Preferred Shares

     1.1    Authorization

     The Company has duly authorized the sale and issuance of up to 3,000,000
shares of its Series A-1 Convertible Preferred Stock (the "Series A-1 Stock")
having the rights, privileges and preferences set forth in the Company's
Restated Certificate of Incorporation (the "Restated Certificate") in the form
attached hereto as Exhibit A.
                   ---------

     1.2    Sale of Preferred

     Subject to the terms and conditions hereof, the Company shall issue and
sell to the Purchasers, and each Purchaser agrees, severally, to purchase at the
Closing, from the Company, shares of Series A-1 Stock (collectively, the
"Shares"), at a purchase price of one dollar ($1.00) per share.  The amount to
be purchased by each Purchaser and the form of consideration therefor is set
forth in the Schedule of Purchasers attached as Schedule 1.  The Purchasers
agree to convert at the Closing, in accordance with Section 1 of the Convertible
Promissory Note(s), held by the Purchasers, the principal amount of such Note(s)
into such number of shares of Series A-1 Stock as specified in Section 1 of the
Notes.

                                                                          PAGE 1

     2.2    Delivery

     Subject to the terms of this Agreement, at the Closing, the Company will

price therefor by check or such other form of payment as set forth on Schedule
1, payable to the order of the Company.

     2.3    Subsequent Rights Offering

     The Company shall, within a 90-day period after the Closing, conduct a
rights offering to the holders of the Company's Common Stock (as defined below)

limit to a Rights Offering to holders of Common Stock of the Company that the
Company believes qualify as accredited investors pursuant to Rule 501 of

Offering, subject to final approval of its structure by VantagePoint Venture

deemed to be "Series A-1 Stock" and shall be deemed to be "Shares" sold pursuant
to this Agreement, any purchasers thereof shall be deemed to be "Purchasers" for
all purposes under this Agreement, and any such subsequent sale shall be deemed
to occur at a "Closing" and the date of any such Closing shall be deemed to be a
"Closing Date."  The Purchasers in the Rights Offering shall become parties to
this Agreement by signing a counterpart signature page hereto.  Should any such
sales be made, the Company shall prepare and distribute to the Purchasers a
revised Schedule of Purchasers reflecting such sales.

     2.4    Subsequent Sales of Shares

     At any time up to 120 days following the Closing, the Company may sell up
to the balance of any shares of Series A-1 Stock not sold at the Closing
authorized under Section 1.1, to such additional investors as may be approved by
the Board of Directors.  All such sales shall be made on the terms and
conditions set forth in this Agreement.  Any Shares sold pursuant to this
Section 2.4 shall be deemed to be "Series A-1 Stock" and shall be deemed to be
"Shares" sold pursuant to this Agreement, any purchasers thereof shall be deemed
to be "Purchasers" for all

                                                                          PAGE 2

purposes under this Agreement, and any such subsequent sale shall be deemed to

     3.9    Proprietary Information; Inventions; Employees and Consultants

          (a)  Since its organization, the Company has taken reasonable security
measures to protect the secrecy, confidentiality and value of all intellectual
property and all Inventions (as defined below).  Except as set forth in Schedule
3.9(a), since its organization, each of the Company's employees, consultants,
and contractors who, either alone or in concert with others, developed,
invented, discovered, derived, programmed or designed intellectual property or
Inventions (as defined below), or who has knowledge of or access to information
about intellectual property or Inventions, has entered into a written agreement
("Proprietary Information Agreement") with the Company which substantially
provides that (i) this intellectual property, other information and Inventions
are proprietary to the Company and are not to be divulged (except as authorized
by the Company), misused or misappropriated, and (ii) this intellectual
property, other information and Inventions are to be disclosed by such
employees, consultants, and contractors to the Company; in cases where this
intellectual property and Inventions may be subject to rights of a third person,
the Company has secured from said third person unrestricted, perpetual,
irrevocable, royalty-free (except to the extent set forth in Schedule 3.10), and
exclusive license rights thereto.  As used herein, "Inventions" means all
inventions, developments and discoveries which during the period of an
employees', consultant's, or contractor's service to the Company he, she or it
makes or conceives of, either solely or jointly with others, that relate to any
subject matter with which his, her, or its work for the Company may be
concerned, or relate to or are connected with the business, products, services
or projects of the Company, or relate to the actual or demonstrably anticipated
research or development of the Company or involve the use of the Company's
funds, time, material, facilities or trade secret information, except as
excluded pursuant to applicable law.

          (b)  Except as set forth in Schedule 3.9(b), the Company is not aware
that any of the Company's employees or consultants is or will be in violation of
his or her Proprietary Information Agreement, and the Company shall use its best
efforts to prevent any such violation.  Except as set forth in Schedule 3.9(b),
the Company is not

                                                                          PAGE 8
<PAGE>

aware that any of the Company's employees or consultants is obligated under any
contract (including licenses, covenants or commitments of any nature) or other
agreement, or subject to any judgment, decree or order of any court or
administrative agency, that would conflict with his or her obligation to use his
or her best efforts to promote the interests of the Company. Neither the
execution nor delivery of this Agreement and the agreements contemplated
thereby, nor the carrying on of the Company's business by its employees and
consultants, nor the conduct of its business as proposed, will conflict with or
result in a breach of the terms, conditions or provisions of, or constitute a
default under, any contract, covenant or instrument known to the Company under
which any of such employees or consultants is now obligated. The Company does
not believe it is or will be necessary to utilize any inventions, copyrights, or
other intellectual property of any of its employees or consultants (or people it
currently intends to hire) made or owned prior to their employment with or
engagement by the Company or that it is or will be necessary to utilize any
other assets or rights of any of its employees or consultants (or people it
currently intends to hire) made or owned prior to their employment with or
engagement by the Company, in violation of any limitations or restrictions to
which any such employee or consultant is a party or to which any of such assets
or rights may be subject.
