         RE:      Form S-8 Registration Statement
                  Cape Systems Group, Inc.

Ladies and Gentlemen:

      At your request, I have examined the form of Registration  Statement which
you are filing with the  Securities  and  Exchange  Commission  on Form S-8 (the
"Registration  Statement"),  in  connection  with  the  registration  under  the
Securities  Act of 1933, as amended,  of up to 13,796,240  shares of your Common
Stock (the "Stock") issuable pursuant to the following agreements:

               Cape Systems Group, Inc. 2004 Incentive Stock Plan
          Agreement with Jeffrey D. Marks, Esq., dated August 18, 2005
           Agreement with Robert P. Schilt, dated September 23 , 2005

      In rendering the following  opinion,  I have examined and relied only upon
the documents and  certificates  of officers and directors of the Company as are
specifically described below. In my examination,  I have assumed the genuineness
of all signatures, the authenticity,  accuracy and completeness of the documents
submitted to me as originals,  and the conformity with the original documents of
all  documents  submitted  to me as copies.  My  examination  was limited to the
following documents and no others:

      1.    Certificate of Incorporation of the Company, as amended to date;

      2.    Bylaws of the Company, as amended to date;

      3.    Certified  Resolutions  adopted  by the  Board of  Directors  of the
            Company authorizing the Plan and the issuance of stock;

      4.    The Registration Statement; and

      5.    The form of Plans.




      I have not  undertaken,  nor do I intend  to  undertake,  any  independent
investigation  beyond any such documents and records,  or to verify the adequacy
or accuracy of such documents and records.

      Based on the foregoing, it is my opinion that the Stock to be issued under
the Plans, subject to effectiveness of the Registration Statement and compliance
with  applicable  blue sky laws, and execution of the Plans in the form referred
to herein,  when issued  under the Plans,  will be duly and validly  authorized,
fully paid and non-assessable.

      I express no opinion as to the  compliance  with the  securities  or "blue
sky" laws of any State in which the Stock is  proposed to be offered and sold or
as to the effect, if any, which  non-compliance with such laws might have on the
validity of issuance of the Stock.

      I consent to the filing of this  opinion as an exhibit to any filing  made
with  the  Securities  and  Exchange  Commission  or  under  any  State or other
jurisdiction's  securities  act for the purpose of  registering,  qualifying  or
establishing  eligibility for an exemption from registration or qualification of
the  Stock  described  in the  Registration  Statement  in  connection  with the
offering  described therein.  Other than as provided in the preceding  sentence,
this opinion (i) is addressed  solely to you, (ii) may not be relied upon by any
other party, (iii) covers only matters of New Jersey and federal law and nothing
in this opinion shall be deemed to imply any opinion  related to the laws of any
other person, and (iv) may not be relied upon for any other purpose  whatsoever.
Nothing herein shall be deemed to relate to or constitute an opinion  concerning
matters not specifically set forth above.

      By giving you this opinion and consent, I do not admit that I am an expert
with respect to any part of the Registration  Statement or Prospectus within the
meaning of the term  "expert"  as used in Section  11 of the  Securities  Act of
1933, as amended,  or the Rules and  Regulations  of the Securities and Exchange
Commission promulgated thereunder.

      The  information  set  forth  herein is as of the date of this  letter.  I
disclaim  any  undertaking  to advise you of changes  which may be brought to my
attention after the effective date of the Registration Statement.

                                      Very truly yours,

                                      LAW OFFICE OF
                                      JEFFREY D. MARKS, P.C.
