investment management agreements with Maverick Fund USA, Ltd. ("Fund USA"),
Maverick Fund, L.D.C. ("Fund LDC") and Maverick Fund II, Ltd. ("Fund II" and
together with Fund USA and Fund LDC, the "Portfolio Funds"), and on behalf of
the Portfolio Funds entered into a Standby Commitment Agreement in relation to
three million dollars ($3,000,000) of debt financing (the




CUSIP No. 096227301                                            Page 7 of 9 Pages


"Commitment Amount"), by and among the Issuer, the Portfolio Funds and certain
other investors (the "Commitment Agreement", a copy of which is attached as
Exhibit B and is incorporated herein by reference in response to this Item 6).

               On July 23, 2008, the Issuer borrowed the full Commitment Amount
pursuant to the Note Purchase Agreement dated July 23, 2008 (the "Note Purchase
Agreement", a copy of which is attached as Exhibit C and is incorporated herein
by reference in response to this Item 6), pursuant to which the Portfolio Funds
acquired Convertible Promissory Notes (the "Notes", copies of which are attached
as Exhibits D, E and F and are incorporated herein by reference in response to
this Item 6) granting to the Portfolio Funds the right to convert the Notes into
a number of Shares equal to the quotient obtained by dividing the aggregate
amount of the principal amount of such Notes to be converted by (i) $3.65 or
(ii) equity securities sold by the Issuer in subsequent rounds of financing for
cash at a conversion price based on the lowest price per share paid by any
investor in such subsequent round of financing. On December 21, 2009, the Issuer
sold Shares at a price of $1.70 per share (the "Conversion Price") to a party
unrelated to the Portfolio Funds, and the Portfolio Funds exercised their rights
to convert the Notes at the Conversion Price into 665,471 Shares.

               On December 21, 2009, the Portfolio Funds, the Issuer, Quantum
Industrial Partners LDC ("QIP"), SFM Domestic Investments, LLC ("SFM" and,
together with QIP, the "Soros Parties"), Prentice Capital Partners, LP, Prentice
Capital Partners QP, LP, Prentice Capital Offshore, Ltd., S.A.C. Capital
Associates, LLC ("SAC"), GPC XL III, LLC, PEC I, LLC (collectively, the
"Prentice Parties"; the Soros Parties, the Portfolio Funds and the Prentice
Parties, collectively, the "Existing Stockholders") and Rho Ventures VI, L.P.
("Rho"; the Soros Parties, the Portfolio Funds, the Prentice Parties and Rho,
collectively, the "Stockholders") entered into an Amended and Restated Voting
Agreement (the "Amended and Restated Voting Rights Agreement", a copy of which
is attached as Exhibit G and is incorporated herein by reference in response to
this Item 6), which amended and restated a voting agreement entered into by the
Issuer and the Existing Stockholders dated as of June 15, 2006.

               Pursuant to Section 1.1 of the Amended and Restated Voting
Agreement, subject to shareholder approval, the Board of Directors of the Issuer
(the "Board") shall be restructured into a classified board upon the closing of
the sale to Rho by the Issuer of the balance of the 8,823,529 Shares not already
purchased by Rho in the first closing (the "Rho Transaction").

               Pursuant to Section 1.2 of the Amended and Restated Voting
Agreement, the Soros Parties are entitled to designate two members to serve on
the Board, Rho is entitled to designate two members to serve on the Board, the
Portfolio Funds are entitled to designate one member to serve on the Board, and
the Prentice Parties (other than SAC) are entitled to designate one member to
serve on the Board.

               Pursuant to Section 1.4 of the Amended and Restated Voting
Agreement, the Stockholders agreed to vote all Shares owned by them in favor of
the persons designated by each of the Stockholders.

               Pursuant to Section 1.5 of the Amended and Restated Voting
Agreement, each of Rho, the Soros Parties, the Portfolio Funds, and the Prentice
Parties (other than SAC) will be entitled to have one director designated by
them serve on any committee of the Board, subject to applicable law, rules and
regulations (including stock exchange regulations), and, if the Issuer
establishes an executive committee of the Board, to have each of their director
designees under the Amended and Restated Voting Agreement serve on such
executive committee of the Board.

               Pursuant to Section 2.1 of the Amended and Restated Voting
Agreement, the Existing Stockholders agreed to vote a specified percentage of
their Shares in favor of the reclassification of the Board and approval of the
Rho Transaction.

               Pursuant to Section 2.2 of the Amended and Restated Voting
Agreement, until 90 days after the date of the Amended and Restated Voting
Agreement, the Portfolio Funds and the Prentice Parties agreed, subject to
certain exceptions, not to, without the prior written consent of the Soros
Parties, Rho and the Issuer sell, offer to sell, or enter into any swap,
arrangement or similar transaction that transfers Shares, or publicly announce
an intention to make such a transaction (the "Lock-Up Restrictions").
Furthermore, if Rho or another person introduced by Rho, makes an offer to the
