(the "BOARD OF DIRECTORS") and other than as set forth in subsection (2) of this
Section 3(A) or Section 3(D) hereof, no further filing, consent or authorization
is required by ShellCo, its stockholders or the Board of Directors. To the
extent that a Subsidiary (which for purposes of this Joinder Agreement shall

party to or bound by a Transaction Document or an Acquisition Document, such
Subsidiary has the requisite power and authority to enter into and perform its
obligations under such Transaction Document or Acquisition Document and the

consummation by such Subsidiary of the transactions contemplated thereby have
been duly authorized by the Board of Directors or equivalent body of such
Subsidiary and no further consent or authorization is required by such
Subsidiary, its equity holders or its board of directors or equivalent body.
This Joinder Agreement, the other Transaction Documents and the Acquisition
Documents to which ShellCo and, if applicable, its Subsidiaries is a party have
been duly executed and delivered by ShellCo and/or such Subsidiary, and
constitute the legal, valid and binding obligations of such parties enforceable
against such parties in accordance with their respective terms, except as such
enforceability may be limited by general principles of equity or applicable
bankruptcy, insolvency, reorganization, fraudulent conveyance or transfer,
moratorium, liquidation or similar laws relating to, or affecting generally, the
enforcement of applicable creditors' rights and remedies. As of the Closing, the
Transaction Documents and Acquisition Documents dated after the date of this
Joinder Agreement and on or prior to the date of the Closing shall have been
duly executed and delivered by ShellCo and, if applicable, its Subsidiaries and
shall constitute the valid and binding obligations of such parties, enforceable
against such parties in accordance with their terms except as enforceability may
be limited by general principles of equity or applicable bankruptcy, insolvency,
reorganization, fraudulent conveyance or transfer, moratorium or similar laws
relating to, or affecting generally, the enforcement of creditors' rights and

from all taxes and Liens in respect of the issue thereof other than Permitted
Liens (as defined in the Notes) and (iii) entitled to the rights set forth in
the Notes. Upon the effectiveness of the Reverse Split, a number of shares of
Common Stock shall have been duly authorized and reserved for issuance which

                                      -2-
<PAGE>

thereafter, at least 10,754,545 shares of Common Stock (subject to adjustment
pursuant to the Company's covenant set forth in Section 4(l) of the Securities
Purchase Agreement) will be duly authorized and reserved for issuance upon
conversion of the Notes and upon exercise of the Warrants. Upon issuance or
conversion in accordance with the Notes or exercise in accordance with the
Warrants, as the case may be, the Conversion Shares and the Warrant Shares,
respectively, will be validly issued, fully paid and nonassessable and free from
all preemptive or similar rights, taxes, liens and charges in respect of the
issue thereof other than Permitted Liens, with the holders being entitled to all
rights accorded to a holder of Common Stock. Subject to the accuracy of the
Buyers' representations and warranties in the Securities Purchase Agreement, the

under the 1933 Act.

            C. NO CONFLICTS. The execution, delivery and performance of this
Joinder Agreement and the Transaction Documents to which it is a party by

parties of the transactions contemplated hereby and thereby (including, without
limitation, the issuance of the Notes and the Warrants, the granting of a
security interest in the Collateral (as defined in the Security Documents) and
reservation for issuance and issuance of the Conversion Shares and the Warrant
Shares) will not (i) result in a violation of any certificate of incorporation,
certificate of formation, any certificate of designations or other constituent
documents of ShellCo or any of its Subsidiaries, any capital stock of ShellCo or
any of its Subsidiaries or bylaws of ShellCo or any of its Subsidiaries or (ii)
conflict with, or constitute a default (or an event which with notice or lapse
of time or both would become a default) under, or give to others any rights of
termination, amendment, acceleration or cancellation of, or other remedy in
respect of any agreement, indenture or instrument to which ShellCo or any of its
Subsidiaries is a party or (iii) result in a violation of any Requirements of
Law, except in the case of clauses (ii) and (iii) of this Section 3(C) for such
conflicts, defaults, rights or violations which would not reasonably be expected
to , individually or in the aggregate have a Material Adverse Effect.

            D. CONSENTS. ShellCo is not required to obtain any consent,

appropriate UCC financing statements with the appropriate states and other
authorities pursuant to the Pledge Agreement and the Security Agreement, (ii)
the other Perfection Requirements (as defined in the Security Agreement), (iii)
the filing with the SEC of one or more Registration Statements in accordance
with the requirements of the Registration Rights Agreement, (iv) a Current
Report on Form 8-K and (v) a Schedule 14C) or registration with, any court,
governmental agency or any regulatory or self-regulatory agency or any other
Person in order for it to execute, deliver or perform any of its obligations
under or contemplated by the Transaction Documents, in each case in accordance
with the terms hereof or thereof. All consents, authorizations, orders, filings
and registrations that ShellCo is required to obtain pursuant to the preceding
sentence prior to the Closing Date have been obtained or effected on or prior to
the Closing Date, and ShellCo and its Subsidiaries are unaware of any facts or
circumstances which might prevent ShellCo from obtaining or effecting any of the
registration, application or filings pursuant to the preceding sentence.

                                      -3-

            E. DILUTIVE EFFECT. ShellCo understands and acknowledges that the
number of Conversion Shares issuable upon conversion of the Notes and the
Warrant Shares issuable upon exercise of the Warrants will increase in certain
circumstances. ShellCo further acknowledges that any obligation to issue
Conversion Shares upon conversion of the Notes in accordance with the Securities
Purchase Agreement and the Notes and its obligation to issue the Warrant Shares
upon exercise of the Warrants in accordance with the Securities Purchase
Agreement and the Warrants is, in each case, absolute and unconditional
regardless of the dilutive effect, which may be substantial, that such issuance
may have on the ownership interests of other stockholders of ShellCo. Taking the
foregoing into account, the Board of Directors has determined in its good faith
business judgment that the issuance of the Notes and the Warrants and the
consummation of the other transactions contemplated hereby are in the best
interests of ShellCo and its stockholders.

            F. INVESTMENT COMPANY. ShellCo is not, and upon the Closing will not
be, an "investment company," a company controlled by an "investment company," or
an "affiliated person" of, or "promoter" or "principal underwriter" for, an
"investment company," as such terms are defined in the Investment Company Act of
1940, as amended.

            G. APPLICATION OF TAKEOVER PROTECTIONS; RIGHTS AGREEMENT. ShellCo
and the Board of Directors have taken all necessary action, if any, in order to
render inapplicable any control share acquisition, business combination, poison
pill (including any distribution under a rights agreement) or other similar
anti-takeover provision under ShellCo's certificate of incorporation (as amended
and restated and in effect on the date hereof, the "CERTIFICATE OF
INCORPORATION") or the laws of the jurisdiction of its formation or otherwise
which is or could become applicable to any Buyer as a result of the transactions
contemplated by the Securities Purchase Agreement, including, without
limitation, ShellCo's issuance of the Securities and any Buyer's ownership of
the Securities. ShellCo has not adopted a stockholder rights plan or similar
arrangement relating to accumulations of beneficial ownership of Common Stock or
a change in control of ShellCo. Certain stockholders of ShellCo, or persons who
upon the consummation of the transactions contemplated by the Transaction
Agreements will become stockholders of ShellCo, representing in the aggregate
approximately 37.3% of the common equity of ShellCo at the consummation of
the transactions contemplated by the Transaction Documents (approximately
14.7% on a fully-diluted basis) have agreed, among other things, to only vote
to increase the authorized number of shares of ShellCo, or amend the certificate
of incorporation of ShellCo or by-laws of ShellCo, if at least 75% of such
stockholders so vote and to vote for Robert Agresti, Gregory DeSaye, Terrance
MacAvery and Raymer McQuiston to a seven person board of directors.

            H. SEC DOCUMENTS; FINANCIAL STATEMENTS.

            1. Since March 3, 2005, ShellCo has filed all reports, schedules,
forms, statements and other documents required to be filed by it with the SEC
pursuant to the reporting requirements of the 1934 Act (all of the foregoing
filed prior to the date hereof and all exhibits

                                       -4-
<PAGE>

included therein and financial statements, notes and schedules thereto and
documents incorporated by reference therein being hereinafter referred to as the
"SEC DOCUMENTS"). ShellCo has delivered to the Buyers or their respective
representatives true, correct and complete copies of the SEC Documents not
available on the EDGAR system. As of their respective dates, the SEC Documents
complied in all material respects with the requirements of the 1934 Act and the
rules and regulations of the SEC promulgated thereunder applicable to the SEC
Documents, and none of the SEC Documents, at the time they were filed with the
SEC, contained any untrue statement of a material fact or omitted to state a
material fact required to be stated therein or necessary in order to make the
statements therein, in the light of the circumstances under which they were
made, not misleading. As of their respective dates, the financial statements of
ShellCo included in the SEC Documents complied as to form in all material
respects with applicable accounting requirements and the published rules and
regulations of the SEC with respect thereto. Such financial statements have been
prepared in accordance with generally accepted accounting principles ("GAAP")
consistently applied, during the periods involved (except (i) as may be
otherwise indicated in such financial statements or the notes thereto, or (ii)
in the case of unaudited interim statements, to the extent they may exclude
footnotes or may be condensed or summary statements) and fairly present in all
material respects the financial position of ShellCo as of the dates thereof and
the results of its operations and cash flows for the periods then ended
(subject, in the case of unaudited statements, to normal year-end audit
adjustments that are not material, individually or in the aggregate). All
written disclosure (other than written disclosure marked "draft", "subject to
completion" or words of similar meaning) provided to the Buyers regarding
ShellCo, the Company, the Targets, their respective businesses and the
transactions contemplated by the Securities Purchase Agreement (including the
Schedules thereto and to this Joinder, the other Transaction Documents and that
certain private placement memorandum dated October 23, 2006), furnished by or on
behalf of ShellCo is true and correct in all material respects and does not
contain any untrue statement of a material fact or omit to state any material
fact necessary in order to make the statements made therein, in the light of the
circumstances under which they were made, not misleading.

            2. None of ShellCo or, to ShellCo's knowledge, any stockholder,
officer, director or of ShellCo has issued any press release or made any other
public statement or communication on behalf of ShellCo or otherwise relating to
ShellCo or any of its Subsidiaries that contains any untrue statement of a
material fact or omits any statement of material fact necessary in order to make
the statements therein, in the light of the circumstances under which they were
made, not misleading or has provided any other information to the Buyers,
including information referred to in Section 2(d) of the Securities Purchase
Agreement, that contains any untrue statement of a material fact or omits to
state any material fact necessary in order to make the statements therein, in
the light of the circumstances under which they were made, not misleading.
Except as set forth on SCHEDULE 3(N) of the Securities Purchase Agreement, which
will be filed with the Form 8-K to be filed by ShellCo pursuant to Section 4(h)
of the Securities Purchase Agreement, none of ShellCo or any of its officers,
directors, employees or agents has provided the Buyers with any material,
nonpublic information. Nothing has come to our attention which would indicate
(i) that the accounting firm of Dale Matheson Carr-Hilton LaBonte, which has
expressed its opinion in respect of the consolidated financial statements of
ShellCo for the fiscal year ended December 31, 2005 (the "AUDIT OPINION") is not
independent of ShellCo pursuant to the standards set forth in Rule 2-01 of
Regulation S-X promulgated by


                                      -5-
<PAGE>

the SEC,   and that such firm was not   otherwise   qualified   to render   the Audit
Opinion and complete   such review under   applicable   law, or (ii) since March 3,
2005, neither ShellCo nor, to the knowledge of ShellCo, any director, officer or
employee, of ShellCo, has received or otherwise had or obtained knowledge of any
material   complaint,   allegation,   assertion or claim,   whether written or oral,
regarding the accounting or auditing   practices,   procedures,   methodologies   or
methods of ShellCo or its internal accounting controls, including any complaint,
allegation,   assertion   or   claim   that   ShellCo   has   engaged   in   questionable
accounting or auditing practices.

            I. CONDUCT OF BUSINESS;   REGULATORY PERMITS. Neither ShellCo nor any
Subsidiary is in violation of any term of its certificate of   incorporation   (or
the   organizational   charter) or bylaws or operating   agreement,   as applicable.
Neither ShellCo nor any Subsidiary is in material violation of any term of or in
material   default   under (or with the   giving of notice or lapse of time or both
would be in violation of or default   under) any   material   contract,   agreement,
mortgage, indebtedness,   indenture, instrument, judgment, decree or order or any
statute,   rule or regulation   applicable to ShellCo or any of its   Subsidiaries.
The business of ShellCo and each   Subsidiary is not being   conducted,   and shall
not be conducted,   in violation in any material   respect of any   Requirements of
Law,   except for such   violation   and/or   possible   violations   which would not,
individually   or in the   aggregate,   reasonably   be   expected to have a Material
Adverse   Effect.    ShellCo   and   each   Subsidiary    possess   all    certificates,
authorizations, licenses and permits issued by the appropriate federal, state or
foreign regulatory   authorities necessary to conduct their respective businesses
as   presently   conducted   ("PERMITS")   except   where the failure to possess such
Permits would not reasonably be expected to have a Material Adverse Effect,   and
none of   ShellCo   or any   Subsidiary   has   received   any   notice of   proceedings
relating to the revocation or modification o
