The Stockholders Agreement was entered into as of May 16, 2005 and amended on July 7, 2005 and on September 16, 2005 by the Company, RFE Investment Partners V, RFE VI SBIC (together with RFE Investment Partners V, the “RFE Entities”), DFW Capital Partners, L.P. (“DFW”), certain other stockholders of PMC, and James A. Parsons, acting as Stockholders’ Agent.  Certain terms and conditions of the Stockholders Agreement are described in Item 4 above.

The Registration Rights Agreement was entered into as of May 16, 2005 and amended on July 7, 2005, by the Company, RFE Investment Partners V, RFE VI SBIC, DFW, certain other stockholders of PMC and James A.

The Escrow Agreement was entered into as of December 9, 2005 by the Company, James A. Parsons, acting as Stockholder Agent, and U.S. Trust Company of California, acting as Escrow Agent.  Certain terms of the Escrow Agreement are described in Item 3 above.

On December 8, 2006, each of RFE Investment Partners V and RFE VI SBIC entered into a Rule 10b5-1 Plan (each, a “Rule 10b5-1 Plan”), in the form filed as Exhibit E to this Schedule 13D, relating to the proposed sale of shares of Common Stock by Jefferies & Company, Inc. (the “Broker”).  Each such Rule 10b5-1 Plan provides that the Broker may sell up to 600,000 shares of Common Stock per calendar quarter (subject to reduction in order to comply with the volume limitations contained in the Registration Rights Agreement), at prices specified in each Rule 10b5-1 Plan.  The maximum number of shares proposed to be sold under each such Rule 10b5-1 Plan is 2,531,435 shares (for each of RFE Investment Partners V and RFE VI SBIC).  The term of each Rule 10b5-1 Plan commences no earlier than 30 days after the date of the final prospectus filed with respect to the Company’s proposed public offering of Common Stock, and continues until the earliest of the earliest to occur of (i) the date on which the Broker is required to suspend or terminate sales under the Rule 10b5-1 Plan, (ii) the date on which the Broker receives notice of the dissolution of the selling stockholder, (iii) the date on which the Company or any other person publicly announces a tender or exchange offer with respect to the Common Stock or a merger, acquisition, reorganization, recapitalization or comparable transaction affecting the securities of the Company as a result of which the Common Stock is to be exchanged or converted into shares of another company, (iv) the date on which the Broker receives notice of the commencement or impending commencement of any proceedings in respect of or triggered by the selling stockholder’s bankruptcy or insolvency, and (v) the date that the aggregate number of shares of Common Stock sold pursuant to the Rule 10b5-1 Plan reaches 2,531,435 shares, unless, in each case, earlier terminated in accordance with the terms thereof.

As reported in the Company’s Current Report on Form 8-K dated January 15, 2007, RFE Entities entered into an Agreement dated as of January 17, 2007, with the Company, DFW, Steelhead Investments Ltd. (“Steelhead”) and, for purposes of Sections 3 and 4 thereof, the RFE Entities (the “Agreement”).  The RFE Entities entered into the Agreement in order to clarify certain matters arising out of DFW’s sale to Steelhead of shares of Common Stock.  The Agreement clarifies that the aggregate Pro Rata Limit of the RFE Entities for purposes of the volume limitations under the Registration Rights Agreement is 2.947% of the total number of shares of Common Stock then outstanding.  See Exhibit G attached to this Amendment No. 2.

As a result of the execution of the Agreement, each of the RFE Entities and the Broker entered into amendments to the Rule 10b5-1 Plans clarifying that the respective Pro Rata Limit of RFE Investment Partners V is 1.471% and the respective Pro Rata Limit of RFE VI SBIC is 1.476%, for a total of 2.947%.  See Exhibit F attached to this Amendment No. 2.
