Explanation of Responses: |
1. Amount of securities beneficially owned following the reported transaction(s) includes Common Units owned and Restricted Units subject to varying vesting terms. |
2. In the merger between MarkWest Hydrocarbon and MarkWest Energy Partners, each restricted share of MarkWest Hydrocarbon was converted to a phantom unit of MarkWest Energy Partners at a ratio of 1.9052 phantom units (rounded up to the nearest whole unit) for each restricted share of MarkWest Hydrocarbon on substantially the same terms. |
3. Pursuant to the merger between MarkWest Hydrocarbon and MarkWest Energy Partners, common units were exchanged for Class B membership interest in the general partner of MarkWest Energy Partners. |
4. Represents a phantom unit, which is a restricted unit that entitles the reporting person to receive a common unit upon the vesting of the phantom unit. Under the grant agreement, the settlement of the phantom units occurs automatically as the phantom units vest, which results in a deemed automatic expiration of the vested portion of the phantom units upon settlement. The phantom units vest over a period of three years with one third vesting on January 31, 2009, 2010 and 2011. |
