FIRST AMENDMENT TO RESTRUCTURING SUPPORT AGREEMENT, dated as of July 20, 2012

its direct and indirect subsidiaries (collectively, the “Company”), the holders
of preferred and common stock in BNHI who are signatories thereto (collectively,
the “Consenting Equity Holders”) and the holders of the Notes who are

with the Consenting Equity Holders, the “Plan Support Parties”).

BACKGROUND

The Company and the Plan Support Parties entered into the Support Agreement in
support of the Restructuring.

The Parties desire to amend and restate certain provisions of the Support
Agreement, as set forth below in this Amendment.

NOW THEREFORE, in consideration of the mutual promises and agreements contained
herein and other good and valuable consideration, the receipt and adequacy of
which are hereby acknowledged, each of the parties hereto hereby agrees as
follows:

Section 1. DEFINED TERMS.

Each defined term used herein and not otherwise defined herein shall have the
meaning ascribed to such term in the Support Agreement.

Section 2 AMENDMENT TO THE SUPPORT AGREEMENT.

 

  2.1 Amendments.

(a) Section 2.1 (b) of the Support Agreement shall be amended and restated to
read as follows:

 

  (b) 11:59 p.m. (EST) on the date that is forty-two (42) days from the date
that Solicitation commences, unless either the Restructuring has been
consummated, or the Chapter 11 Cases have commenced in the Bankruptcy Court;

(b) Section 2.1 (r) of the Support Agreement shall be amended and restated to
read as follows:

 

  (r)

with respect to each Required Consenting Noteholder (and, for the avoidance of
doubt, not with respect to any party signing a Joinder (as defined below) in
connection with any disposition of any Notes by a Required Consenting
Noteholder), if the transactions contemplated by the Restructuring: (i) result
in regulatory requirements or filings (disclosure or otherwise), other than
(x) initial Federal Communications Commission or state public utility commission
filings that contain information of a type set forth on Schedule A, (y) a
statement filed in compliance with Rule 2019 of the Federal Rule of Bankruptcy
Procedure, or (z) a routine tax filing; or (ii) cause other legal requirements,
restrictions or obligations (other than that expressly undertaken by the
execution of this Support Agreement) that are not

--------------------------------------------------------------------------------

  acceptable or otherwise not satisfactory to such Required Consenting
Noteholder, in its sole and absolute discretion; provided that such Required
Consenting Noteholder and the other Parties have used commercially reasonable
efforts to avoid or modify any such applicable requirements, filings,
restrictions, or obligations by proposing to the Parties modified series,
classes or terms of the securities the Required Consenting Noteholder is to be
offered in connection with the Restructuring prior to such Required Consenting
Noteholder asserting a Noteholder Termination Event under this Section 2.1;
provided, further that the undertaking of the Required Consenting Noteholders in
this Section 2.1(r) to use commercially reasonable efforts shall not be
construed as an obligation of any Required Consenting Noteholder to disclose
financial or other information other than that which is expressly agreed to in
this Section 2.1(r).

(c) Section 2.5 (b) of the Support Agreement shall be amended and restated to
read as follows:

 

  (b) Noteholder Termination Event Procedures. Upon the occurrence of (i) a
Noteholder Termination Event under subsections 2.1 (h), (j), (l), (n) or (o) of
this Support Agreement, this Support Agreement shall terminate automatically
without further action, (ii) the Company withdrawing the Plan (if applicable),
publicly announcing its intention not to support the Plan or filing any plan of
reorganization and/or disclosure statement that is materially inconsistent with
the Term Sheet, this Support Agreement shall terminate automatically without
further action, and (iii) a Noteholder Termination Event under subsections
2.1 (a), (b), (c), (d), (e), (f), (g), (i), (k), (m), (p), (q) or (r) of this
Support Agreement, this Support Agreement shall terminate three (3) Business
Days after counsel to the Required Consenting Noteholders (or in the case of
subsection 2.1(r), counsel to any Required Consenting Noteholder) shall have
given written notice to the Company of the intent to terminate this Support
Agreement and the breach or other matter giving rise to the right to so
terminate this Support Agreement shall not have been cured during the three
(3) Business Day period after receipt of such notice (the date of termination
under clause (i), (ii) or (iii) hereof, the “Noteholder Termination Date”). The
automatic stay arising pursuant to section 362 of the Bankruptcy Code shall be
deemed waived or modified for purposes of providing notice hereunder. Except as
otherwise provided herein, upon termination of this Support Agreement, the
Consenting Noteholders shall be released from their respective commitments,
undertakings and agreements under or related to this Support Agreement and shall
have the rights and remedies that they would have had and shall be entitled to
take all actions that they would have been entitled to take had they not entered
into this Support Agreement. Without limiting the foregoing, in the event of a
termination of this Support Agreement for any reason, each Consenting Noteholder
shall have the right to withdraw any vote in support of the Plan and revoke any
acceptance of an offer to exchange its Notes in its sole and absolute discretion
and the Company agrees that it shall not oppose such withdrawal or revocation

(d) Section 8.1 (a) of the Support Agreement shall be amended and restated to
read as follows:

 

  (a)

Each Plan Support Party hereby agrees, severally and not jointly, for so

--------------------------------------------------------------------------------

  long as this Support Agreement shall remain in effect, not to sell, assign,
transfer, hypothecate or otherwise dispose of any Equity or Notes unless, as a
condition precedent to any such transaction, the transferee thereof executes and
delivers a Joinder (as defined in Section 8.1(c) hereof) to the Company at least
two (2) Business Days prior to the relevant transfer. Thereafter, such
transferee shall be deemed to be a Consenting Noteholder (but not a Required
Consenting Noteholder) or Consenting Equity Holder, as applicable, for purposes
of this Support Agreement.

(e) Section 8.1 (c) of the Support Agreement shall be amended and restated to
read as follows:

 

  (c) Any person that receives or acquires Notes or Equity pursuant to a sale,
assignment, transfer, hypothecation or other disposition of such Notes or Equity
by a Plan Support Party hereby agrees to be bound by all of the terms of this
Support Agreement (as the same may be hereafter amended, restated or otherwise
modified from time to time) (a “Joining Party”) by executing and delivering a
joinder in the form of Exhibit C hereto (the “Joinder”). The Joining Party shall
thereafter be deemed to be a “Consenting Noteholder” (but not a Required
Consenting Noteholder) or “Consenting Equity Holder,” as applicable, and a Party
for all purposes under this Support Agreement
