If a Series A Conversion Notice is delivered by a Series A Preferred Unitholder to the Partnership or a Series A Forced Conversion Notice is delivered by the Partnership to a Series A Preferred Unitholder, each in accordance with Section 5.8(b)(vi)(C), the Partnership shall issue the applicable Series A Conversion Units no later than three Business Days after the Series A Conversion Notice Date or the Series A Forced Conversion Notice Date, as the case may be, occurs (any date of issuance of such Common Units, and any date of issuance of Common Units upon conversion of Series A Preferred Units pursuant to this Section 5.8(b)(vi) or Section 5.8(b)(vii), a “Series A Conversion Date”). On the Series A Conversion Date, the Partnership shall instruct, and shall use its commercially reasonable efforts to cause, its Transfer Agent to electronically transmit the Series A Conversion Units to such Series A Preferred Unitholder. The Series A Preferred Unitholders and the Partnership agree to use commercially reasonable efforts to coordinate with the Transfer Agent to accomplish this objective. Subject to Section 5.8(b)(i)(D), upon issuance of Series A Conversion Units to the Series A Converting Unitholder, all rights under the converted Series A Preferred Units shall cease, and such Series A Converting Unitholder shall be treated for all purposes as the Record Holder of such Series A Conversion Units.

To convert Series A Preferred Units into Common Units pursuant to Section 5.8(b)(vi)(A), a Series A Converting Unitholder shall give written notice (a “Series A Conversion Notice”) to the Partnership stating that such Series A Preferred Unitholder elects to so convert Series A Preferred Units pursuant to Section 5.8(b)(vi)(A), the number of Series A Preferred Units to be converted.

Following such time as the BlackRock Purchaser ceases to own Series A Preferred Units, the BlackRock Purchaser may continue to give or receive notices pursuant to the foregoing on behalf of any other Series A Purchase Agreement Purchaser or any of its Affiliates who are required to provide notice through the BlackRock Purchaser under this Section. A Series A Conversion Notice shall be considered given under this Section when such notice is actually received by the Partnership at both of the following physical addresses (or such other address or addresses as the Partnership may designate in writing to the BlackRock Purchaser from time to time):
