Re: $2,700,000 Standby Financing Commitment

Dear Mr. Mee:

Clarus Capital Corp., a Hong Kong company and James P. King, (collectively,
“we”, or “our”), understand that Fortified Holdings Corp., a Nevada corporation
(the “Company”), through its wholly owned subsidiary, Fortified Data
Communications, Inc., a Delaware corporation, intends to acquire all of the
issued and outstanding membership interests of Z5 Technologies LLC, a
Connecticut limited liability company, from Thomas Keenan Ventures, LLC, a
Delaware limited liability company (“TK Ventures”), pursuant to the terms of a
certain agreement and plan of merger, dated May 31, 2007, as amended (together,
the “Merger Agreement”). All capitalized terms not otherwise defined herein
shall have the definition ascribed to them in the Merger Agreement.

You have advised us that as a condition to the closing of the transaction
contemplated by the Merger Agreement (the “Merger”), the Company must first
consummate or enter into an agreement to consummate, subject only to the Closing
of the Merger, a financing transaction in an aggregate principal amount of no
less than Two Million Seven Hundred Thousand Dollars ($2,700,000) funded on or
after August 31, 2007.

In connection with the forgoing, we, intending to be legally bound, hereby
jointly and severally irrevocably commit to provide the Company with up to an
aggregate principal amount of Two Million Seven Hundred Thousand Dollars
($2,700,000) (the “Commitment Funds”) upon the terms and subject to the
conditions as set forth in this commitment letter (this “Commitment Letter”).
Our commitment with respect to those amounts set forth in the schedule of
availability annexed hereto as Exhibit A (the “Availability Schedule”) that are
to be made available on or after the Closing Date is based upon and subject to
the Closing of the Merger on or before September 12, 2007, after which date we
may terminate this Commitment Letter in accordance with the immediately
following paragraph, subject to the limitations set forth therein. If (i) the
Closing has not occurred on or before September 12, 2007 but occurs subsequent
to that date and (ii) we have not terminated this Commitment Letter prior to the
Closing in accordance with the immediately following paragraph, we will, upon
the Company’s request, make all interim payments provided for in the
Availability Schedule and not made through such Closing Date on or within two
Business Days of the Closing Date, subject to any offset as provided for in
Section 3 hereof.

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

If the Closing has not occurred on or before September 12, 2007, then at any
time on or after September 13, 2007 and before the time that the Closing does in
fact occur, we may terminate this Commitment Letter by written notice to the
Company; provided that we may not so terminate this Commitment Letter if all
conditions to the Closing of the Merger were met on or before September 12, 2007
excepting those conditions that have not been met as a result of the continued
pendancy of that certain litigation against the Company (and others) by Aegis
Industries, Inc., a Delaware corporation and others and currently pending in the
State of Nevada, County of Washoe, in which case the Commitment Letter shall
terminate only in the event that the Merger Agreement is terminated by the
parties to such agreement.

          1     . Availability of Funds. The Commitment Funds may be drawn upon
by the Company, in its sole discretion, in one or more tranches in accordance
with the Availability Schedule. Upon requests given from time to time by the
Company in writing (including electronic communications) requesting funds in
amounts and as of dates no greater than the amounts and no earlier than the
dates set forth in Availability Schedule, we will advance such funds to the
Company by wire transfer of immediately available funds, in each case on or
before the later of (a) the applicable Date of Availability as set forth in the
Availability Schedule, or (b) the second Business Day following the applicable
funding request. Except as provided in Section 2 hereof, any Commitment Funds
drawn upon by the Company shall be evidenced by an unsecured convertible
promissory note (a “Note”) substantially in the form annexed hereto as Exhibit
B.

          2.      Subsequent Financings. At such time as the Company consummates
one or more subsequent private financing transactions (a “Subsequent Financing”)
wherein it raises a minimum aggregate amount of Five Hundred Thousand Dollars
($500,000) through the sale and issuance of its equity or equity-linked
securities, any and all additional Commitment Funds drawn upon by the Company
pursuant to the terms of this Commitment Letter shall be invested in the Company
on terms substantially identical to the terms of such Subsequent Financing in
lieu of the Company’s issuance of a Note.

          3.      Offset of Funds. The aggregate principal amount of the
Commitment Funds available to the Company pursuant to the terms of this
Commitment Letter shall be offset by the gross amount funded to the Company
through any Subsequent Financing on a dollar-for-dollar basis, with such
Subsequent Financing proceeds being applied against the next scheduled
Commitment Funds available to be drawn in accordance with the terms of the
Availability Schedule. By way of example, if as of September 22, 2007 the
Company has raised $900,000 in a Subsequent Financing and we have funded
$850,000 to the Company pursuant to the terms of this Commitment Letter, then we
would not be obligated to provide any additional Commitment Funds to the Company
until October 26, 2007; provided, further, that the Company has not raised any
additional funds through a Subsequent Financing.

          4.      Enforcement by TK Ventures. The parties agree that TK Ventures
is an intended third party beneficiary of this Commitment Letter, and if the
Company shall fail, within a reasonable time, to enforce its rights under this
Commitment Letter following any failure by us to perform our obligations
hereunder, then TK Ventures shall be entitled to enforce this Commitment Letter
in the name of and on behalf of the Company.

          5.      Miscellaneous. This Commitment Letter may be executed in one
or more counterparts, each of which shall be deemed to be an original and all of
which, taken together, shall constitute one and the same agreement. This
Commitment Letter may be amended, and our obligations hereunder may be waived,
only by the written agreement of us and the Company and

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

with the written consent of TK Ventures. This Commitment Letter shall be
governed by, and construed in accordance with, the laws of the State of Nevada.
