Section 1.1 in the form of a Common Stock Investment, and (ii) each such Funding
Party (not including LJCB) or its affiliates shall elect to convert the entire
amount of the outstanding principal of (A) the Prior Note (as hereinafter

      to (aa) for Gleacher, 757,604 divided by 3,000,000, (bb) for Phillips,
      303,915 divided by 3,000,000 and (cc) for ZAM Holdings, 1,938,481 divided

      provided by this clause (3); and provided further, that adjustments shall
      be made in the event that the Prior Note is subdivided to equitably
      apportion the amounts referred to in this clause (3) among the other three
      Funding Parties. Notwithstanding the foregoing, there shall be no
      reduction pursuant to this clause (3) to the extent that (I) the Prior
      Note is held by First Republic Bank through the date of the closing of the
      applicable Funding, (II) no Funding Party has exercised its rights to
      cause the assignment of such Prior Note, (III) the mandatory assignment
      provision applicable with respect to such Prior Note has not become
      effective, (IV) neither First Republic Bank nor any direct or indirect
      assignee of any of its rights under the Prior Note or with respect to the
      indebtedness reflected in connection therewith has demanded payment
      pursuant to the Guaranty and (V) there has not occurred any event of
      default or breach by the Company under the agreements or instruments
      entered into in connection with such indebtedness (including, without

      (including, for purposes of determining the Funding Party's existing
      ownership, the outstanding warrants held by the Funding Parties) relative
      to that of each other stockholder of the Company, including, without
      limitation, by reducing, at such Funding Party's option, the
      Over-subscription Privilege that may be exercised by any such other
      stockholder and the Aggregate Offering Cap.

material respects as at the respective dates thereof and the consolidated
results of its operations and cash flows for the periods indicated in accordance
with GAAP (subject, in the case of the Interim Financial Statements, to normal

Governmental Entity, arbitrator or other person which (a) in any manner

public statement without the prior consent of the other parties (which consent
shall not be unreasonably withheld or delayed), except as may be required by Law
or any listing rules of, or listing agreement or arrangement with, a national
securities exchange to which the Company is a party.

      Section 6.7 Notification of Certain Matters. The Company shall give notice

provisions, covenants and restrictions of this Agreement shall remain in force
and effect and shall in no way be affected, impaired or invalidated so long as
the economic and legal substance of the transactions contemplated hereby is not
affected in any manner materially adverse to any party. Upon such determination,
the parties shall negotiate in good faith to modify this Agreement so as to
effect the original intent of the parties as closely as possible in an
acceptable manner in order that the transactions contemplated hereby be
consummated as originally contemplated to the fullest extent possible.

affiliates, attorneys and agents and all of its respective heirs, successors,
legal administrators and permitted assigns (collectively, the "Indemnitees")
from and against any and all liability, loss, cost, damage, reasonable
attorneys' and accountants' fees and expenses, court costs and all other
out-of-pocket expenses incurred by any or all of the Indemnitees in connection
with any investigation, litigation or proceeding relating to or arising from the
execution, delivery and performance by the Company of the Transaction
Agreements, the Rights Offering, any Funding and any other transactions related
hereto or thereto (including, without limitation, the Company's use of the
Collateral, as defined in the New Company Notes), and the consummation of all
such transactions, except to the extent of any willful misconduct or gross
negligence of the Indemnitees. This indemnification provision will be in
addition to the rights of each and all of the Indemnitees to bring an action
against the Company for breach of any term of this Agreement or any other
Transaction Agreement. The Company acknowledges and agrees that each and all of
the Indemnitees shall be treated as third party beneficiaries with rights to
bring an action against the Company under this Section 9.10.

      (b) A Funding Party shall give the Company prompt notice of any
third-party claim that may give rise to any indemnification obligation under
this Section 9.10, together with the estimated amount of such claim, and the
Company shall have the right to assume the defense (at the Company's expense) of
any such claim through counsel of the Company's own choosing by

                                       18

so notifying the Funding Party within thirty (30) days of the first receipt by
the Company of such notice from the Funding Party; provided, however, that any
such counsel shall be reasonably satisfactory to the Funding Party. Failure to
give such notice shall not affect the indemnification obligations hereunder in
the absence of actual and material prejudice. From and after the date the
Company notifies the Funding Party of its assumption of the defense of a
third-party claim, the Company will not be liable for any fees or expenses of
separate counsel incurred by a Funding Party; provided that (i) if, under
applicable standards of professional conduct, a conflict with respect to any
significant issue between any Indemnitee and the Company would reasonably be
expected to exist in respect of such third-party claim, the Company shall pay
the reasonable fees and expenses of such additional counsel as may be required
to be retained in order to resolve such conflict and (ii) the Company shall be
liable for the fees and expenses of counsel employed by the Funding Party or an
Indemnitee for any period during which the Company has not assumed the defense
of any such third-party claim (other than during any period in which the Funding
Party will have failed to give notice of the third-party claim as provided
above). If the Company assumes such defense, the Funding Party shall have the
right to participate in the defense thereof and to employ counsel, at its own
expense, separate from the counsel employed by the Company. If two or more of
the Funding Parties or Indemnitees may be entitled to indemnification from the
Company as parties to any proceeding, the Company may require each party to use
the same legal counsel as the other parties; provided, however, that each party
shall be entitled to separate legal counsel if a conflict with respect to any
significant issue between the Indemnitees would reasonably be expected to exist.
If the Company chooses to defend or prosecute any third-party claim, the Funding
Party shall agree to any settlement, compromise or discharge of such third-party
claim that the Company may recommend and that, by its terms, discharges the
Funding Party and the Indemnitees from the full amount of liability in
connection with such third-party claim; provided, however, that, without the
consent of the Funding Party, the Company shall not consent to, and the Funding
Party shall not be required to agree to, the entry of any judgment or enter into
any settlement that (A) provides for injunctive or other non-monetary relief
affecting the Funding Party or any Indemnitee or (B) does not include as an
unconditional term thereof the giving of a release from all liability with
respect to such claim by each claimant or plaintiff to each Indemnitee that is
the subject of such third-party claim. Notwithstanding anything in this
Agreement to the contrary, the Company shall have no obligation to indemnify any
Funding Party or Indemnitee under this Agreement for any amounts paid in
settlement of any proceeding without the Company's prior written consent, which
may not be unreasonably withheld or delayed. The Company may offset (1) any
unpaid amount for which a Funding Party or an Indemnitee is determined to be
liable to the Company pursuant to any proceeding, claim, issue or matter
determined by final judgment or other final adjudication, not subject to further
appeal or review, against (2) any indemnification payment required to be made by
the Company pursuant to this Section 9.10 to such Funding Party or Indemnitee.

      Section 9.11 Survival of Representations and Warranties, etc. All
representations and warranties made in, pursuant to or in connection with this
Agreement will survive the execution and delivery of this Agreement
indefinitely, notwithstanding any investigation at any time made by or on behalf
of any party hereto; and all statements contained in any certificate, instrument
or other writing delivered by or on behalf of any party hereto required to be
made pursuant to the terms of this Agreement or required to be made in
connection with or in contemplation of the transactions contemplated by this
Agreement will constitute representations and warranties by such party pursuant
to this Agreement.
