Purchaser to, any governmental or regulatory authority.

     5.5. INVESTIGATION; ECONOMIC RISK. Purchaser acknowledges that it has been
furnished with, or has had made available to it, information regarding the risks
of purchasing the Shares and the Additional Shares (as defined below). Purchaser
further acknowledges that it has had an opportunity to discuss the business,
affairs and current prospects of the Company with its officers and has been
provided an opportunity to ask questions of, and has received answers thereto
satisfactory to Purchaser from, the Company and Parent. Purchaser further
acknowledges having had access to all other information about the Company that
it has requested.

     5.6 EVALUATION OF AND ABILITY TO BEAR RISK. Purchaser has such knowledge
and experience in financial affairs that Purchaser is capable of evaluating the
merits and risks of an investment in the Shares and the Additional Shares.
Purchaser has not relied in connection with this investment upon any
representations, warranties or agreements other than those set forth in this
Agreement. Purchaser's financial situation is such that Purchaser can afford to
bear the economic risk of holding the Shares and the Additional Shares for an
indefinite period of time, and Purchaser can afford to suffer the complete loss
of Purchaser's investment in the Shares and the Additional Shares.

     5.4. PURCHASE FOR INVESTMENT. Purchaser is purchasing the Shares (and may
receive the Additional Shares) pursuant to this Agreement for Purchaser's own
account and not with a view to or for sale in connection with any distribution

any of the Shares or Additional Shares. Purchaser hereby agrees that Purchaser
will not, directly or indirectly, transfer, offer, sell, pledge, hypothecate or
otherwise dispose of all or any part of the Shares or Additional Shares or
Purchaser's interest in any of the Shares or Additional Shares (or solicit any
offers to buy, purchase or otherwise acquire or take a pledge of all or any part
thereof) except in accordance with the terms of the Stockholders Agreement (as
defined below) and in a manner that does not violate the registration or any
other applicable provisions of the Act (or any other applicable federal
securities laws) or any applicable state securities laws. Purchaser understands
that Purchaser must bear the economic risk of an investment in the Shares and
the Additional Shares for an indefinite period of time because, among other
reasons, the offering and sale of the Shares and the Additional Shares have not
been registered under the Act, and therefore, the Shares and Additional Shares
cannot be sold unless they are subsequently registered under the Act or an
exemption from such registration is available. Purchaser also understands that
sales or transfers of the Shares and Additional Shares will be further
restricted by the provisions of the Stockholders Agreement and applicable state
securities laws.

will provide to Parent and the Company including, but not limited to,
Purchaser's financial position and knowledge of financial and business matters,
is true, correct and complete as of the date of execution of this Agreement and
will be true, correct and complete as of the Closing Date. Purchaser undertakes
to provide promptly to Parent and the Company written notice of any material
changes in Purchaser's financial position or otherwise and such information will
be true, correct and complete as of the date given and as of the Closing Date.
Purchaser understands that Parent and the Company will rely in a material degree
upon the representations contained herein.

                                 INDEMNIFICATION

     8.1. INDEMNIFICATION BY PARENT AND THE COMPANY. Parent and the Company
shall, jointly but not severally, save, defend, indemnify and hold harmless
Purchaser and its officers, directors, employees, agents, successors and assigns
from and against any and all losses, damages, liabilities, deficiencies, claims,
interest, awards, judgments, penalties, costs and expenses (including reasonable
attorneys' fees, costs and other out-of-pocket expenses incurred in
investigating, preparing or defending the foregoing) (collectively, the
"LOSSES") to the extent resulting from any breach of any representation or
warranty made by Parent or the Company contained in this Agreement and any
breach of any covenant or agreement by Parent or the Company contained in this
Agreement. Losses covered by this Article VIII shall be referred to herein as
"COVERED LOSSES".

     8.2 INDEMNIFICATION BY PURCHASER. Purchaser shall save, defend, indemnify
and hold harmless Parent and the Company, their officers, directors, employees,
agents, successors and assigns from and against any and all Covered Losses to
the extent arising out of or resulting from any breach of any representation or
warranty made by Purchaser contained in this Agreement and any breach of any
covenant or agreement by Purchaser contained in this Agreement.

     8.3 LIMITATIONS ON INDEMNIFICATION.

          (a) For purposes of determining those Covered Losses which will be
     subject to indemnification under this Article VIII, the parties have agreed
     to use predictable dollar thresholds. Accordingly, the parties hereto agree
     that with respect to any representation or warranty referred to in Sections
     8.1 or 8.2, if such representation or

                                       10

<PAGE>

     warranty contains a materiality qualification, such materiality
     qualification shall be disregarded and only the dollar thresholds stated in
     this Section 8.3 shall apply.

          (b) Parent and the Company shall have no liability for indemnification
     pursuant to Section 8.1 with respect to Covered Losses unless such Covered
     Losses exceed in the aggregate $30,000 (the "THRESHOLD"), in which case
     Parent and the Company shall be liable for all Covered Losses in excess of
     the Threshold; provided, however, that the total liability of Parent and
     the Company with respect to Covered Losses shall not exceed, in the
     aggregate, $150,000 (the "CAP").

          (c) Purchaser shall have no liability for indemnification pursuant to
     Section 8.2 with respect to Covered Losses unless such Covered Losses
     exceed in the aggregate the Threshold, in which case Purchaser shall be
     liable for all Covered Losses in excess of the Threshold; provided,
     however, that the total liability of Purchaser with respect to Covered
     Losses shall not exceed, in the aggregate, the Cap.

     8.4 EXCLUSIVE REMEDY. From and after the Closing, this Article VIII shall
be the exclusive remedy of the parties hereto for any Covered Losses arising out
of any breach of the representations, warranties, covenants or agreements of the
Parties contained in this Agreement. Notwithstanding the foregoing, nothing set
forth herein shall limit the rights, remedies and claims of any party hereto
with respect to the fraudulent acts or willful breach of another party.

     8.5 SURVIVAL. The representations and warranties in this Agreement shall
terminate on the date that is twelve (12) months following the Closing Date. The
covenants and agreements of the parties that contemplate performance at or prior
to the Closing shall terminate on the date that is twelve (12) months following
the Closing Date. The covenants and agreements of the Parties that by their
terms are to be performed in whole or in part after the Closing shall survive
the Closing and terminate on the date that is twelve (12) months after the date
on which such covenant and agreement is to be performed.

                                   ARTICLE IX

                                   TERMINATION

     9.1. TERMINATION. This Agreement may be terminated at any time prior to the
Closing pursuant to the following:

          (a) Mutual Consent. This Agreement may be terminated by mutual written
     consent of each of the Parties.

          (b) Outside Date. This Agreement may be terminated by any of the
     Parties if the Closing shall not have occurred by April 30, 2007 (the
     "OUTSIDE DATE"); provided, that no party may terminate this Agreement
     pursuant to this Section 9.1(b) if that party has breached its obligations
     under this Agreement in a manner that shall have proximately contributed to
     the failure of the Closing to occur by such date.

          (c) Failure to Perform. By either Parent or the Company, on the one
     hand, or Purchaser, on the other hand, if (i) with respect to termination
     by Parent or the Company,

                                       11

<PAGE>

     there has been a breach of any covenant or representation or warranty of
     Purchaser contained in this Agreement or (ii) with respect to termination
     by Purchaser, if there has been a breach of any covenant or representation
     or warranty of Parent or the Company contained in this Agreement, and in
     either case such breach would cause the failure of any condition precedent
     set forth in Article VII to be satisfied; provided, that in the case of a
     breach that maybe cured, any such breach of a covenant or representation or
     warranty has not been cured within thirty (30) days following receipt by
     the breaching party of written notice of such breach.

          (c) Government Order. By any of the Parties in the event that any
     governmental authority shall have issued an order, decree or ruling or
     taken any other action restraining, enjoining or otherwise prohibiting the
     transactions contemplated by this Agreement and such order, decree, ruling
     or other action shall have become final and nonappealable.

     The party seeking to terminate this Agreement pursuant hereto shall give
prompt written notice of such termination to the other party.

     9.2 Effect of Termination. In the event of termination of this Agreement as
provided herein, this Agreement shall forthwith become void and there shall be
no liability on the part of either party; provided; however, that nothing herein
shall relieve either party from liability for any breach of this Agreement or
any agreement made as of the date hereof or subsequent thereto pursuant to this
Agreement.

                                    ARTICLE X
