Dear Joe,

We are pleased to extend you an offer to join Rackspace, first as an Accounting

We are offering you a bi-weekly salary of $10,576.92, which is $275,000.00
annualized.  In addition to your annual pay, you will have an opportunity to
earn 50% of your salary with the Semi-Annual Rackspace Profit Sharing Plan.  You
must be employed at the time of the bonus payout in order to be eligible for the
Profit Sharing Plan. The Company also offers an excellent benefits package
including medical, dental, disability, life insurance and 401(k). You are
eligible to begin your participation in our benefits on your hire date.

In  addition, you will be awarded an equity award, valued at $550,000 (based on
accounting value at the time of grant), pending final approval by our
compensation committee in accordance with our equity award policies and
procedures. Half of the grant value would be issued in the form of at-the-money
stock options, with a strike price equal to the closing share price at the date
of the grant. The other half would be issued in the form of restricted share
units in our parent corporation, Rackspace Hosting, Inc. The equity awards are
expected to be granted within 90 days of your employment commencement date. The
equity awards will be issued pursuant to the Rackspace Hosting, Inc. 2007
Amended and Restated Long Term Incentive Plan and our standard form of Stock
Option (time-vesting) and Restricted Stock Unit (time-vesting) Agreements.

Also, pending additional approvals from the compensation committee and based on
your satisfactory performance in your role at Rackspace (which determination
shall be at the sole discretion of your Rackspace supervisor), two additional
equity awards, identical in amount and form as the award described above, may be
granted to you. Such awards would be subject to the then-current form of
applicable agreement as approved by the compensation committee. The awards would
be tentatively scheduled to be awarded at the next two Company performance
review periods (currently scheduled for August 2012 and February 2013) and stock
options would be granted with a strike price equal to the share closing share
price at the date of the grant.

We are offering you our Fanati-Black relocation package which includes a full
pack and move and a lump sum relocation advance of $35,000. These benefits will
be administered by our relocation partner, Relocation Synergy. Upon execution of
the offer letter and relocation repayment agreement, Relocation Synergy will
contact you to assist you in your relocation. A full summary of relocation
benefits is attached. After being employed by Rackspace for 1 year, then no
advance will be required to be repaid.

The contents of this letter do not form an employment contract or alter your
at-will employment status.  All Company personnel are at-will employees.  This
means that either the Company or the employee may terminate the employment
relationship at any time, for any reason or no reason.  Only the Chief Executive
Officer may enter into any agreement to the contrary, whether verbal or written,
with any employee.  If the Chief Executive Officer should choose to enter into
an agreement to the contrary, it must be a written agreement signed by him to be
valid. 

Again, we are pleased to represent Karl Pichler in offering you the opportunity
to join Rackspace.

Sincerely,

Rackspace Employee Services

I accept the offer to join Rackspace as a Chief Accounting Officer with Karl
Pichler and agree to the terms outlined above.
