The Series A Conversion Units shall be issued in the name of the Record Holder of such Series A Preferred Units. A Series A Converting Unitholder who is a Series A Purchase Agreement Purchaser (or an Affiliate thereof) may only provide a Series A Conversion Notice through the BlackRock Purchaser as and to the extent provided in Section 5.8(b)(vi)(A), and the BlackRock Purchaser may not transfer any of the rights or obligations to give or receive notices under this Section (on behalf of itself and/or any Series A Purchase Agreement Purchaser or any of its or their Affiliates) without the express written consent of the Partnership. 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.

The Series A Conversion Units shall be issued in the name of the Record Holder of such Series A Preferred Units.

Timing. 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.
