At such time that Capital Account Alignment is achieved, a Class C Unit will convert automatically into a Common Unit. Class C Units (including Class C Units received in respect of a year) will be allocated their share of taxable income based on their percentage interests, except as otherwise determined by the Issuer. Hereinafter, the Common Units, including the Class C Units, are collectively referred to herein as the "Common Units".

On January 7, 2015, pursuant to the terms of the Deferred Fee Agreement, 130,264 Class B Units were issued to WGL by the Issuer.

The right to receive such Class C Units was previously assigned to SPH SPV by SP General Services. On May 1, 2014, the capital account allocable to a Class C Unit equaled the capital account allocable to a regular Common Unit and, therefore, all then outstanding Class C Units converted automatically into regular Common Units. Subsequent to the May 1, 2014 conversion, 340,926 Common Units were withdrawn from SPH SPV.

On January 7, 2015, the Issuer and SPH SPV entered into that certain Incentive Unit Agreement (the "Incentive Unit Agreement"), effective as of May 11, 2012, to restate the provisions related to the Incentive Units from the Management Agreement without substantive change.
