and in the 2004 Stock-Based Compensation Plan (the “Plan”) and in the West

Outside Directors (the “Deferred Compensation Plan”).

2.        Stock Units Credited to Your Deferred Compensation Plan “C” Account.
All Stock Units will be credited to your “C” Account under the Deferred
Compensation Plan, and shall be deemed to be “Stock Equivalents” for all
purposes under the Deferred Compensation Plan. The Plan is the successor to the
Stock Equivalents Plan as defined in the Deferred Compensation Plan.

2.    Amendment.        The Committee shall have the power unilaterally and
without approval of the Director to amend this Stock Unit in order to carry out
the purposes of the Plan and the Deferred Compensation Plan so long as such an
amendment does not take away any benefit granted to the Director by this Stock
Unit and as long as the amended Stock Unit comports with the terms of the Plan
and the Deferred Compensation Plan.

4.     Interpretation. The Committee shall have the sole power to resolve any
dispute or disagreement arising out of this Stock Unit Award Agreement. The
Committee’s interpretation and construction of any provision of this Stock Unit
or the Plan shall be final and conclusive and, insofar as possible, shall be
consistent with the requirements of stock units. Except to the extent preempted
by any applicable federal law, this Stock Unit will be construed and
administered in accordance with the laws of the Commonwealth of Pennsylvania,
without reference to the principles of conflicts of law of such state.

5.     Plan Document. This Stock Unit is subject to the applicable terms and
conditions of the Plan and the Deferred Compensation Plan, which are
incorporated herein by reference, and in the event of any contradiction,
distinction or differences between this Stock Unit Award Agreement and the terms
of the Plan, the terms of the Plan will control. All capitalized terms used
herein, not otherwise defined herein, shall have the meanings set forth in the
Plan or Deferred Compensation Plan, as applicable.

6.     Entire Agreement. This Stock Unit Award Agreement, including the terms
and conditions of the Plan and the Deferred Compensation Plan, is intended by
the parties as a final expression of their agreement and intended to be a
complete and exclusive statement of the agreement and understanding of the
parties hereto in respect of the subject matter contained herein. This Stock
Unit Award Agreement supersedes all prior agreements and understandings between
the parties with respect to such subject matter.

        You must sign and return a copy of this Stock Unit Award Agreement to
the Secretary of the Company. Your executed copy must be returned within sixty
(60) days, otherwise, this Stock Unit will lapse and become null and void as of
its inception. Therefore, intending to be legally bound, the parties have
executed this Stock Unit Award Agreement in two counterparts as of the Grant
Date.
