directors and BSMB agree.  3.             Advisory
Fee.  (a)           In
consideration of BSMBs undertaking to provide advisory services hereunder, the
Company shall pay BSMB an annual advisory fee (the Advisory Fee) in an
amount for each fiscal year equal to the greater of (x) $500,000 and (y) 0.75%
of Adjusted EBITDA of the Company and its subsidiaries for the immediately
preceding fiscal year, calculated as provided below and payable in advance in
quarterly installments, for the period beginning on the date hereof and ending
upon the termination of this Agreement as provided in Section 1 hereof; provided,
that the annual Advisory Fee for the fiscal year ending December 31, 2007 shall
be $500,000. The Advisory Fees shall be payable by the Company whether or not
the Company actually requests that BSMB provide the services described in Section 2
above. All Advisory Fees shall be fully earned when paid.  (b)           The
first installment of the Advisory Fee, for the period beginning on the date
hereof and ending June 30, 2007, shall be payable on the date hereof
(unless otherwise directed by BSMB) in an amount equal to $125,000 multiplied
by a fraction, (i) the numerator of which is the actual number of days

(ii) the denominator of which is 90.  (c)           Except
as otherwise provided in Section 3(d) or 3(e) hereof,
all subsequent payments of the Advisory Fee shall be in quarterly installments,
payable on March 31, June 30, September 30 and December 31
of each year, in an amount equal to the greater of (x) $125,000 or (y)the product of (i) 25% and (ii) 0.75% of
Adjusted EBITDA of the Company and its subsidiaries for the immediately
preceding fiscal year; provided, that the portion of the Advisory Fee
payable on September 30, 2007 and December 31, 2007 shall be $125,000 each.  (d)           Upon
a Company Sale or the consummation of a Qualified Public Offering, the Company
shall be obligated to pay to BSMB the Advisory Fee that would be payable to
BSMB pursuant to this Section 3 in respect of the next four
successive three-month periods calculated based on the Advisory Fee paid or
payable for the then current three-month period.  (e)           Notwithstanding
anything to the contrary contained herein, the Company shall accrue but not pay
the Advisory Fee if and for so long as (i) any such payment would constitute
a default (or any event which might, with the lapse of time or the giving of
notice or both, constitute a default) under the Companys financing agreements
(a Default); provided, that the Company shall be obligated to
pay any accrued Advisory Fees deferred under this clause (i) to the extent
that such payment would not constitute a Default or (ii) BSMB instructs
the Company not to pay all or any portion of the Advisory Fee during any fiscal
year. Interest will accrue on all due and unpaid Advisory Fees not paid
pursuant to clause (i) of the preceding sentence at the Default Rate until
such Advisory Fees are paid, and such interest shall compound annually.  2


(f)            In
addition to the Advisory Fee, the Company shall reimburse BSMB, promptly upon
request, for all reasonable out-of-pocket expenses incurred in the ordinary
course of business by BSMB in connection with BSMBs obligations hereunder,
including fees and expenses paid to consultants, subcontractors, advisors and
other third parties in connection with such obligations.  4.             Transaction
Fees. The Company hereby agrees to pay to BSMB upon the date hereof a fee
(the Closing Fee) for services rendered in connection with securing,
structuring and negotiating the acquisition, equity and debt financing for the
transactions contemplated by the Merger Agreement and certain other management
services in an amount equal to $10,000,000. The Closing Fee shall be payable by
wire transfer of immediately available funds to BSMB or one or more of its
designees. In addition, the Company shall either pay directly or reimburse BSMB
for all of the reasonable out-of-pocket fees and expenses, including legal and
accounting fees, incurred by BSMB or any of its affiliates (other than the
Company or any of its subsidiaries) in connection with the negotiation and
execution of the Merger Agreement and the consummation of the transactions
contemplated by the Merger Agreement.  5.             Personnel.
BSMB shall provide and devote to the performance of this Agreement such
partners, employees and agents of BSMB as BSMB shall deem appropriate to the
furnishing of the services required.  6.             Liability.

the Company or its subsidiaries or affiliates for any loss, liability, damage
or expense (collectively, a Loss) arising out of or in connection with
the performance of services contemplated by this Agreement, unless and then
only to the extent that such Loss is determined by a court in a final order
from which no appeal can be taken, to have resulted solely from the gross
negligence or willful misconduct on the part of such member of the BSMB Group. BSMB
makes no representations or warranties, express or implied, in respect of the
services to be provided by the BSMB Group. Except as BSMB may otherwise agree
in writing on or after the date hereof: 
(a) each member of the BSMB Group shall have the right to, and

or similar business activities or lines of business as the Company or its
subsidiaries and (ii) do business with any client, customer, supplier,
lender or investor of, to or in the Company or its subsidiaries; (b) no
member of the BSMB Group shall be liable to the Company or its subsidiaries or
affiliates for breach of any duty (contractual or otherwise) by reason of any
such activities or of such persons participation therein; and (c) in the
event that any member of the BSMB Group acquires knowledge of a potential
transaction or matter that may be a corporate opportunity for both (A) the
Company or any of its subsidiaries, on the one hand, and (B) BSMB, on the
other hand, or any other person, no member of the BSMB Group shall have any
duty (contractual or otherwise) to communicate or present such corporate
opportunity to the Company or its subsidiaries and, notwithstanding any
provision of this Agreement to the contrary, shall not be liable to the
Company, its subsidiaries or any of their affiliates for breach of any duty
(contractual or otherwise) by reasons of the fact that any member of the BSMB
Group directly or indirectly pursues or acquires such opportunity for itself,
directs such opportunity to another person, or does not present such
opportunity to the Company, its subsidiaries or any of their affiliates. In no
event will any of the parties hereto be liable to any other party hereto for any
punitive, exemplary, indirect, special, incidental or consequential damages,
including lost profits or savings, whether or not such damages are foreseeable,
or in  3


respect of any liabilities relating to any third party
claims (whether based in contract, tort or otherwise), other than for the
Claims (as defined in Section 7) relating to the services which may
be provided by BSMB hereunder.  7.             Indemnity.
The Company and its subsidiaries shall defend, indemnify and hold harmless each
member of the BSMB Group from and against any and all Losses arising from any
claim by any person with respect to, or in any way related to, this Agreement
(including attorneys fees) (collectively, Claims) resulting from any act
or omission of any member of the BSMB Group except to the extent that such Loss
is determined by a court in a final order from which no appeal can be taken to
have resulted solely from the gross negligence or willful misconduct of such
member of the BSMB Group. The Company and its subsidiaries shall defend at its
own cost and expense any and all suits or actions (just or unjust) which may be
brought against the Company and its subsidiaries or any member of the BSMB
Group, or in which any member of the BSMB Group may be impleaded with others
upon any Claims, or upon any matter, directly or indirectly, related to or
arising out of this Agreement or the performance of the obligations hereunder
by the BSMB Group, except that if such damage shall be proven to result solely
from gross negligence or willful misconduct by a member of the BSMB Group, then
such member of the BSMB Group shall reimburse the Company and its subsidiaries
for the costs of defense and other costs incurred by the Company and its
subsidiaries.  8.             Notices.
