Shareholder (as defined below).

NOW, THEREFORE, IN CONSIDERATION of the mutual covenants contained in this
Agreement, and for other good and valuable consideration, the receipt and
adequacy of which are hereby acknowledged, the Company and the undersigned
Shareholder agree as follows:

1.     Six Month Prohibition on Sales or Transfers. The Shareholder, including
the Shareholder’s Affiliated Entities (as defined below), hereby agrees that for
a period of six (6) months from the Effective Date (the “Lock-Up Period”), the
Shareholder will not offer, sell, contract to sell, pledge, give, donate,
transfer or otherwise dispose of, directly or indirectly, any shares of the
Company’s common stock $0.01 par value per share (the “Common Stock”) or
securities convertible into or exercisable for Common Stock issued to the
Shareholder pursuant to the Share Exchange (the “Lock-Up Shares”) or securities
or rights convertible into or exchangeable or exercisable for any Lock-Up
Shares, enter into a transaction which would have the same effect, or enter into
any swap, hedge or other arrangement that transfers, in whole or in part, any of
the economic or voting consequences of ownership of such securities, whether any
such aforementioned transaction is to be settled by delivery of the Lock-Up
Shares or such other securities, in cash or otherwise, or publicly disclose the
intention to make any such offer, sale, pledge or disposition, or to enter into
any such transaction, swap, hedge or other arrangement (the “Lock-Up
Agreement”). As used in this Agreement “Affiliated Entities” shall mean any
legal entity, including any corporation, limited liability company, partnership,
not-for-profit corporation, estate planning vehicle or trust, which is directly
or indirectly owned or controlled by the Shareholder or his or her descendants
or spouse, of which such Shareholder or his or her descendants or spouse are
beneficial owners, or which is under joint control or ownership with any other
person or entity subject to a lock-up agreement regarding the Company’s stock
with terms substantially identical to this Agreement.

2.     Post-Lock-Up Restrictions on Sales—Volume Limitations – Leak-Out. After
the expiration of the Lock-Up Period and for the six (6) month period
thereafter, the aggregate number of Lock-Up Shares that may be sold or otherwise
Transferred (as defined below) by the Shareholder (taking into account sales and
other Transfers (a) directly from the Shareholder, (b) by the Shareholder’s
Affiliated Entities and (c) by any holder of Lock-Up Shares previously sold or
otherwise Transferred to such holder by the Shareholder after the Effective Date
(but taking into account only Lock-Up Shares transferred to the holder by the
Shareholder)) shall not exceed (i) 10% of the average monthly trading volume for
the Common Stock on the relevant trading market as reported by Bloomberg L.P.
for any Shareholder who is not an “affiliate” of the Company as such term is
defined under the Securities Act of 1933, as amended (the “Act”), and (ii) the
greater of (x) 5% of the average monthly trading volume for the Common Stock on
the relevant trading market as reported by Bloomberg L.P., or (y) the maximum
amount permitted under applicable law or regulation for any Shareholder who is
an “affiliate” (as adjusted for any stock split, combination or the like) in any
30-day period (the “Volume Limitations”).
 
 
 

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

 
 
3.     Allowable Sales During Lock-Up Period and Thereafter. Notwithstanding the
terms of Section 1 above, during the Lock-Up Period the Shareholder may:
 
(a)           Transfer Lock-Up Shares to the Company or its designee.

(b) Make a bona fide charitable donation to a non-profit, religious organization
or institution that is independent of the Shareholder (a “Charitable Donee”).

(c) Grant and maintain a bona fide lien or security interest in, pledge,
hypothecate or encumber (collectively, a “Pledge”) any Lock-Up Shares
beneficially owned by him, her or it to a nationally or internationally
recognized financial institution with assets of not less than $10 billion (an
“Institution”) in connection with a loan to the Shareholder; provided, however,
that (i) the Shareholder (treating the Shareholder and all Shareholder’s
Affiliated Entities in the aggregate as one entity) shall not Pledge Lock-Up
Shares to secure loans in the aggregate in excess of One Million Dollars
($1,000,000); (ii) the Shareholder gives the Company’s Secretary 5 days’ prior
written notice that he, she or it intends to Pledge Lock-Up Shares to an
Institution pursuant to this Section 3(c); and (iii) the Institution agrees in
writing at or prior to the time of such Pledge that the Company shall receive
timely notice of any margin call or event of default and shall have the right to
satisfy any margin call or cure any event of default by the Shareholder in
connection with any loan to which the Pledge relates by purchasing any or all
Lock-Up Shares Pledged at a price equal to 50% of the then-current market value
(as calculated using the average closing sales price of the Company’s Common
Stock for the 15 immediately previous trading days) on the date of the margin
call or event of default, such election by the Company to be shown by written
notice to the Institution and payment within 5 business days of notice being
received by the Company, with transfer of the Lock-Up Shares to the Company to
be completed immediately upon receipt of such payment. In the event that the
Company’s payment for the Lock-Up Shares exceeds the amount owed to the
Institution by the Shareholder, any excess amount shall be paid promptly by the
Institution to the Shareholder. In the event that both the Company and the
Shareholder attempt to make payment to satisfy any margin call or event of
default, the first to make full payment shall be deemed to have completed such
purchase or cure (as the case may be), and any payments received by the
Institution from the other party shall be promptly returned. This paragraph may
not be relied upon for any non-bona fide loan or other form of indirect or
disguised sale.  The Shareholder hereby appoints and constitutes Randall E.
McCoy, with full power of substitution, as attorneys-in-fact (each an
“Attorney-in–Fact”) to act in the Shareholder’s name, place and stead, to
transfer and convey to the Company all Lock-Up Shares purchased by the Company

coupled with an interest and is irrevocable. The Shareholder agrees to indemnify
and hold the Company and each Attorney-in-Fact, or their appointees, harmless
from and against any and all liabilities, claims, damages and expenses
(including attorney’s fees and court costs) incurred by the Company or an
