Ground Lease between he Data Centers LLC and
I 743 Holdings, LLC - Notice of Termination

Re:

Dear Mr. Kern:

I write on behalf of 1743 Holdings, LLC (?1743?) regarding the December
21, 2012 Ground Lease Agreement (?Ground Lease?) between 1743 and The Data
Centers, LLC In accordance with 9.1, 9.1.l and 17.2 of the Ground
Lease, this letter serves as notice of termination for reasons set forth below:

1. TDC has failed to commence construction within the time limits required by
9.1 and 9.11 of the Ground Lease.

2. Under 6.1 of the Ground Lease, use of the Premises must be
?commensurate with a first class science and technology campus.? Similarly, 
9.2(i) requires that proposed improvements and their use be ?consistent with high-
quality development and a first class science and technology campus.? 1743 has
repeatedly advised that proposal to build 279MW of generating capacity is
not consistent with that standard and has suggested that TDC scale down its
proposed generation facilities. TDC has refused to do so and apparently continues
to prepose a generation facility of unprecedented scale; indeed, a facility with.
twice the capacity of the model to which our attention was drawn by TDC. 
refusal to plan for a facility consistent with the standard articulated in the Ground
Lease constitutes a breach justifying termination under 17.Mr. Earl Eugene Kern, CEO

For these reasons, 1743 hereby terminates the Ground Lease. Please make
arrangements to surrender possession of the Premises and remove any items not
belonging to 1743.

Please let me know if you have'any questions.

Sincerely,

Scott R. Douglass
