(c)                                  Each Purchaser represents, severally with respect to itself only, that neither the execution and delivery of this Agreement by such Purchaser nor the consummation of the transactions contemplated herein (i) conflicts with or results in a breach of any of the terms, conditions or provisions of the organizational documents of such Purchaser or any agreement or instrument to which such Purchaser is a party or by which the material assets of such Purchaser are bound or (ii) constitutes a default under any of the foregoing, violates any law or regulation, except to the extent that any conflict, breach or default under this subsection (c) would not prevent or materially hinder the performance of the actions contemplated by this Agreement.

(e)                                  Each Purchaser represents, severally with respect to itself only, that its performance of this Agreement will not violate any order, writ, injunction, decree or demand of any court or Governmental Authority to which such Purchaser is subject.

(f)                                   Each Purchaser represents and warrants, severally with respect to itself only, that no agent, broker, investment banker, financial advisor or other person or entity is or will be entitled, by reason of any agreement, act or statement by it or any of its representatives to any

4

financial advisory, broker’s, finder’s or similar fee or commission, to reimbursement of expenses or to indemnification or contribution in connection with the transactions contemplated hereby.

(g)                                  All Purchased Shares acquired by or for each Purchaser are and will be acquired solely for such Purchaser’s own account for investment purposes only and not with a present view toward the distribution thereof or with any present intention of distributing or reselling any such Purchased Shares in violation of the Securities Act or any state securities laws.  Irrespective of any other provisions of this Agreement, any sale of any of the Purchased Shares acquired by each Purchaser will be made only in compliance with all applicable federal and state securities laws, including the Securities Act.

(h)                                 Each Purchaser is aware of the need to conduct its own investigation of the Purchased Shares and has had the opportunity to ask questions and receive answers concerning the Purchased Shares acquired by or for such Purchaser.  Each Purchaser has had full access to such information and materials concerning Premier and its subsidiaries as each Purchaser has requested.  Premier has answered all inquiries that each Purchaser has made to Premier relating to Premier and its subsidiaries or the Purchased Shares acquired by such Purchaser.

(i)                                     Each Purchaser is able to fend for itself in the transactions contemplated by this Agreement and has such knowledge and experience in financial and business matters such that such Purchaser is capable of evaluating the merits and risks of an investment in the Purchased Shares and of making an informed investment decision with respect thereto, or has consulted with advisors who possess such knowledge and experience.

(j)                                    Each Purchaser is able to bear the economic risk of its investment in the Purchased Shares for an indefinite period of time.  Each Purchaser understands that the Purchased Shares have not been registered under the Securities Act and therefore cannot be sold unless subsequently registered under the Securities Act or unless an exemption from such registration is available.

The risk factors described therein are not the only ones that Premier faces or that may relate to an investment in the Purchased Shares.  Any of these risks, alone or in combination with other risks, could result in a material and adverse impact upon the business, financial condition, results of operations, plans or prospects of Premier.  In such case, the value of the Purchased Shares could decline, and each Purchaser could lose part or all of its investment in Premier.

(l)                                     Premier is relying upon the truth and accuracy of the representations, warranties and acknowledgements of each Purchaser and each Purchaser agrees that if any of the representations, warranties and acknowledgements deemed to have been made by such Purchaser

5

by its execution of this Agreement are no longer accurate, it shall promptly notify Premier. Each Purchaser consents to such reliance.
