Section 5 - Corporate Governance and Management

Item 5.02  Departure of Directors or Certain Officers; Election of Directors;
Appointment of Certain Officers; Compensatory Arrangements of Certain
Officers.

(e)  Pursuant to the terms of the Diamond Hill Fixed Term Deferred
Compensation Plan (the "Fixed Term Plan") and the Diamond Hill Variable Term
Deferred Compensation Plan (the "Variable Term Plan" and along with the Fixed
Term Plan, each a "Plan" and collectively, the "Plans"), as adopted by the
Board of Directors of Diamond Hill Investment Group, Inc. (the "Company") on
April 24, 2013, the Board of Directors of the Company approved amendments on
May 21, 2013 to each of the Plans.  R. H. Dillon, the Company's President and
Chief Executive Officer, is currently eligible to participate in the Variable
Term Plan, along with each person employed by the Company or any of its
affiliates as a portfolio manager or research analyst who is a member of a
select group of management or highly compensated employees.  James F. Laird,
the Company's Secretary, Treasurer and Chief Financial Officer, is eligible
to participate in the Fixed Term Plan, along with each person employed by the
Company or any of its affiliates who is not a portfolio manager or
research analyst.  Complete descriptions of the terms and conditions of the
Plans are provided in the Report on Form 8-K filed by the Company on April 30,
2013.  Brief descriptions of the amendments to the Plans are provided below.
The descriptions of the amendments to the Plans are qualified in their entirety
by reference to the First Amendment to the Fixed Term Plan and the First
Amendment to the Variable Term Plan, copies of which are attached hereto as
Exhibits 10.1 and 10.2, respectively.

Amendment to Fixed Term Plan

     The Board of Directors of the Company amended the terms of the Fixed Term
Plan to allow participants to elect whether to receive distributions from the
Fixed Term Plan (i) in one lump sum payment within 90 days following the
fifth anniversary of the date the incentive compensation was deferred, or
(ii) in up to five substantially equal annual installments beginning on the
January 1 following the fifth anniversary of the date such incentive
compensation was deferred and on each January 1 thereafter.  The Fixed Term
Plan previously provided only for distribution in the single lump sum payment.
The remainder of the Fixed Term Plan has not changed.

Amendment to Variable Term Plan

     The Board of Directors of the Company amended the terms of the Variable
Term Plan to allow participants, upon making an election to receive the
distributions of incentive compensation in annual installments instead of a
single lump sum payment, to elect to receive such distributions from the
Variable Term Plan in up to fifteen substantially equal annual installments
beginning on the January 1 following either: (A) the participant's Termination
(as defined in the Variable Term Plan) and on each January 1 thereafter; or
(B) the earlier of (1) a date specified by the participant on the deferral
election form and every January 1 thereafter, or (2) the participant's
Termination and on each January 1 thereafter.  Previously, the Variable Term
Plan provided the option for distributions of up to only five substantially
equal annual installments.

     The Board of Directors of the Company also amended the Variable Term
Plan to specify who is eligible to make a subsequent deferral election under
the terms of the Variable Term Plan after the initial deferral election form
has been submitted.  The Variable Term Plan previously permitted anyone,
whether an active or former employee, to make a subsequent deferral election
to change the time and form of distributions.  The Variable Term Plan now
only permits active employees (those who have not Terminated, as defined in
the Variable Term Plan), to change the time and form of distributions.  The
remainder of the Variable Term Plan has not changed.
