This Amendment (the “Amendment”) to The Hackett Group, Inc. 1998 Stock Option
and Incentive Plan, as amended and restated as of March 16, 2015 (the “Plan”),
which provides certain protection for recipients of awards under the Plan who

The Plan hereby is amended by adding the following new definition in
alphabetical order to Section 2:

“Cause” shall have the meaning, with respect to a Grantee, as set forth in any
employment agreement between the Company or any Affiliate and the Grantee;
provided, however, that in the absence of an employment agreement containing
such definition, “Cause” means, with respect to a Grantee:

 

(a)

the commission of a felony or a crime involving moral turpitude or the
commission of any other act or omission involving dishonesty or fraud with
respect to the Company or any of its Subsidiaries or any of their customers or
suppliers;

 

(b)

conduct tending to bring the Company or any of its Subsidiaries into substantial
public disgrace or disrepute;

 

(c)

substantial and repeated failure to perform Grantee’s duties, and such failure
is not cured within 30 days after the Grantee receives notice thereof;

 

(d)

gross negligence or willful misconduct with respect to the Company or any of its

any breach of any confidentiality, non-solicitation or non-competition agreement
to which Grantee is bound.

of Section 18.3:

“In the event a Grantee’s Grant is assumed, continued, or substituted for in
accordance with the immediately preceding sentence, and his or her employment or
service is terminated without Cause within twelve (12) months following the
consummation of such Change of Control, the Grantee shall be immediately vested
in the unvested portion of his or her Grant as of such termination of employment
or service. For the avoidance of doubt, the immediately preceding provision
shall apply to all Grants under the Plan, regardless of when granted.”
