Gentlemen:

      Reference is made to the Investor Rights  Agreement,  dated as of June 28,
2006,  as amended,  among  GlobalOptions  Group,  Inc. (the  "Company")  and the
purchasers   listed  on  SCHEDULE  1  attached  thereto  (the  "Investor  Rights
Agreement") and the letter,  dated February 21, 2007 (the "North Sound Letter"),
among the Company,  North Sound Legacy International Ltd. and North Sound Legacy
Institutional Fund LLC (collectively, "North Sound"). Capitalized terms used but
not defined  herein shall have the meanings  given to such terms in the Investor
Rights Agreement.

      In accordance  with Section 7(h) of the Investor Rights  Agreement,  North
Sound,  which,  as of the date  hereof,  holds in  excess of a  majority  of the
Registrable Securities,  hereby waives any and all rights and remedies under the
Investor Rights  Agreement (i) with respect to the Company's  obligation,  under
Sections 2 and 3(a) of the Investor Rights  Agreement,  to keep the Registration
Statement  continuously  effective  under the  Securities  Act during the period
commencing on the date hereof and ending on the earlier of (a) the effectiveness
of the New  Registration  Statement (as defined  below) and (b) the date that is
120 days after the date hereof (such period,  the  "Suspension  Period") and any
and all obligations that the Company may have under Sections 3(b)(i),  3(b)(ii),
3(b)(iv), 3(c)(C), 3(d), 3(e), 3(g), 3(h), 3(i), 3(j), 3(l) and (with respect to
the Company's obligations when there is not an effective  Registration Statement
covering  all  of the  Registrable  Securities)  7(d)  of  the  Investor  Rights
Agreement during the Suspension Period, and (ii) under Sections 7(a), 7(e), 7(f)
and 7(g)(i) of the Investor Rights  Agreement with respect to (x) any failure by
the Company to perform any of such obligations during the Suspension Period, (y)
the withdrawal of the Registration Statement during the Suspension Period or (z)
the  filing  of,  and  causing  to be  declared  effective,  a new  Registration
Statement  covering  Registrable  Securities  at any time during the  Suspension
Period (the "New  Registration  Statement"),  which New  Registration  Statement
shall be  deemed  to be a  Registration  Statement  for all  purposes  under the
Investor Rights Agreement.  It is acknowledged  that,  pursuant to the foregoing
waiver,  the  Company  may  withdraw  the  Registration   Statement  during  the
Suspension  Period, and such withdrawal shall not be deemed to be an Event under
the Investor Rights Agreement.

      North Sound  further  acknowledges  that the Company  shall be required to
include,  as to North Sound,  only the Registered  Securities (as defined in the
North Sound Letter) in the New  Registration  Statement,  and that North Sound's
Remaining  Securities (as defined in the North Sound Letter) shall be registered
as contemplated in the North Sound Letter;  provided,  however, that the Company
shall use its  reasonable  best  efforts  to  include  North  Sound's  Remaining
Securities in the New  Registration  Statement as and to the extent permitted by
applicable  federal  securities  laws,  rules,  regulations and  interpretations
thereof; provided, further, however, that the Company's inability to include any
Remaining  Securities  in  the  New  Registration   Statement  shall  not  cause
Liquidated  Damages  (as  defined in the North  Sound  Letter) to be incurred or
accrue. Each of North Sound and the Company hereby reaffirms its obligations and
waivers  contained  in the North Sound  Letter,  except that North Sound  hereby
acknowledges that the Company's obligation to use its reasonable best efforts to
file and cause to be declared  effective the Additional  Registration  Statement
(as defined in the North Sound  Letter)  shall be tolled for the duration of the
Suspension Period.
