FIRST AMENDMENT TO OFFICE LEASE

        This FIRST AMENDMENT TO OFFICE LEASE ("First Amendment"), dated for
reference purposes as of March 12, 2010, by and between KILROY REALTY, L.P., a
Delaware limited partnership ("Landlord"), and BRIDGEPOINT EDUCATION, INC., a
Delaware corporation ("Tenant").

R E C I T A L S:

        A.    WHEREAS Landlord and Tenant entered into that certain Office Lease
dated as of January 31, 2008 (the "Lease"), whereby Landlord leases to Tenant
and Tenant leases from Landlord approximately 147,533 rentable square feet of
space (the "Premises") constituting the entirety of the building located and
addressed at 13500 Evening Creek Drive North, San Diego, California (the
"Building"). The Building is part of the office building project commonly known
as "Kilroy Sabre Springs."

        B.    WHEREAS Tenant previously subleased a space comprising a total of
9,849 rentable square feet of space and commonly known as Suite 160 (the
"Suite 160 Premises"), constituting a portion of the premises leased to
Countrywide Home Loans, Inc., a New York corporation, by Landlord under that
certain lease agreement dated as of July 31, 2004, as amended.

        C.    WHEREAS pursuant to the terms of the Lease, the parties
contemplated that the Suite 160 Premises would become part of the Premises
effective November 1, 2009.

        D.    WHEREAS the sublease pursuant to which Tenant subleased the
Suite 160 Premises actually expired on November 30, 2009, and therefore the date
upon which the Suite 160 Premises became a part of the "Premises" under the
Lease is different from that otherwise set forth therein.

A G R E E M E N T :

        NOW, THEREFORE, in consideration of the foregoing recitals and the
mutual covenants contained herein, and for other good and valuable
consideration, the receipt and sufficiency of which are hereby acknowledged, the
parties hereto hereby agree as follows:

        1.    Terms.    All capitalized terms when used herein shall have the
same respective meanings as are given such terms in the Lease unless expressly
provided otherwise in this First Amendment.

        2.    The Suite 160 Premises.    Landlord and Tenant hereby acknowledge
and agree that effective as of December 1, 2009, the Suite 160 Premises became
part of the "Premises." Accordingly, and notwithstanding any provision to the
contrary contained in this Lease, the Suite 160 Premises was deemed delivered to
Tenant on December 1, 2009, even though no actual delivery of the Suite 160
Premises occurred due to Tenant's continued occupancy of the Suite 160 Premises
during such time period. Tenant shall continue to accept the Suite 160 Premises
in its presently-existing "as is" condition, and Tenant hereby agrees that the
Suite 160 Premises is currently in good and sanitary order, condition and
repair, subject only to (i) latent defects to the extent identified and,
thereafter, promptly communicated to Landlord, and (ii) Landlord's ongoing
obligations set forth in Sections 1.1.3 and 29.33, and Articles 7 and 24 of the
Lease.

        3.    Base Rent.    Landlord and Tenant hereby acknowledge and agree
that due to the fact the Lease Commencement Date with respect to the Suite 160
Premises is now December 1, 2009, the second and

--------------------------------------------------------------------------------

third rows (i.e., starting with the row whose first cell reads "July 1, 2009
through October 31, 2009") of the Base Rent Schedule set forth in Section 4 of
the Summary of Basic Lease Information attached to the Lease are to be deleted
and replaced with the following:

July 1, 2009 through
November 30, 2009   75,288   $[***]   $[***]
December 1, 2009 through
June 30, 2010
 
85,137
 
$[***]
 
$[***]

        4.    Tenant's Share.    Notwithstanding anything set forth in the Lease
to the contrary, effective as of December 1, 2009 (and not November 1, 2009),
Tenant's Share is to be determined based on Tenant then-occupying 85,137
rentable square feet of space.

        5.    Confidentiality.    Section 29.28 of the Lease is hereby amended
and restated in its entirety as follows.

"Confidentiality. Tenant acknowledges that the content of this Lease and any
related documents are confidential information. Tenant shall keep such
confidential information strictly confidential and shall not disclose such
confidential information to any person or entity other than Tenant's financial,
legal, and space planning consultants, and except as required to be disclosed by
any Applicable Law," as that term is defined in Article 24 of the Lease,
including, without limitation, in the event Tenant is a publicly traded company
on one of the nationally recognized securities exchanges (such as, without
limitation, NYSE or NASDAQ), any disclosures required by the Securities and
Exchange Commission."

        6.    Broker.    Landlord and Tenant hereby warrant to each other that
they have had no dealings with any real estate broker or agent in connection
with the negotiation of this First Amendment, and that they know of no real
estate broker or agent who is entitled to a commission in connection with this
First Amendment. Each party agrees to indemnify and defend the other party
against and hold the other party harmless from any and all claims, demands,
losses, liabilities, lawsuits, judgments, costs and expenses (including without
limitation reasonable attorneys' fees) with respect to any leasing commission or
equivalent compensation alleged to be owing on account of any dealings with any
real estate broker or agent, occurring by, through, or under the indemnifying
party. The terms of this Section 6 shall survive the expiration or earlier
termination of the term of the Lease, as hereby amended.

        7.    No Further Modification.    Except as specifically set forth in
this First Amendment, all of the terms and provisions of the Lease shall remain
unmodified and in full force and effect.
