A.   The Secured Party is the holder of certain Convertible Debentures issued by
     the Companies to the Secured Party.

B.   In connection with certain Securities  Purchase  Agreements,  the Companies
     have agreed, upon the terms and subject to the conditions of the Securities
     Purchase  Agreements,  to issue to the  Secured  Party (i) the  Convertible
     Debentures,  and  (ii)  certain  warrants  to  be  exercisable  to  acquire
     additional  shares of common stock as set forth in the Securities  Purchase

     Security Documents.

     a Delaware limited liability company ("GS COES") have entered into a Credit
     Agreement,  dated as of January  11,  2008,  pursuant  to which the Secured
     Party may make loans to GS COES from time to time (the "GS COES Loans").

E.   Each of the  Guarantors  has executed and delivered  (i) a Global  Security
     Agreement,  dated as of the date hereof (as may be amended and supplemented
     from  time to time,  the  "Security  Agreement"),  pursuant  to  which  the

     documents related to such financial accommodations.

     NOW,  THEREFORE,  in consideration of the premises and the mutual covenants
set forth herein, and for other good and valuable  consideration the receipt and
sufficiency of which is hereby  acknowledged,  each  Guarantor  hereby agrees as
follows:

SECTION 1         Guaranty.

1.1      Guaranty.

     (a)  Each  Guarantor,  as direct  obligor and not merely as surety,  hereby
          unconditionally, absolutely, and irrevocably guarantees to the Secured
          Party  the  full  payment  and  prompt   performance  of  all  of  the
          Obligations.  Without  limiting the foregoing,  the Guarantors  hereby
          agree that upon any Event of Default, the Guarantors shall immediately
          pay or perform any Obligations without notice,  demand or formality of
          any kind.

     (b)  The term  "Obligations"  shall  mean and  include  any and all  debts,
          liabilities,  obligations, covenants and duties owing by any Guarantor
          to the  Secured  Party,  now  existing or  hereafter  arising of every
          nature,  type,  and  description,  whether  liquidated,  unliquidated,
          primary, secondary, secured, unsecured, direct, indirect, absolute, or
          contingent,  and whether or not evidenced by a note, guaranty or other
          instrument,  and any  amendments,  extensions,  renewals or  increases
          thereof,  including,  without  limitation,  all  those  under  (i) the
          Transaction  Documents;  (ii) any agreement or document related to the
          Transaction  Documents;  or (iii) any other or related documents,  and
          including   any   interest    accruing   thereon   after   insolvency,
          reorganization or like proceeding relating to the Guarantors,  whether
          or  not  a  claim  for  post-petition  interest  is  allowed  in  such
          proceeding,  and all costs and expenses of the Secured Party  incurred
          in the enforcement,  collection or otherwise in connection with any of
          the foregoing,  including,  but not limited to, reasonable  attorneys'
          fees and expenses and all obligations of the Guarantors to the Secured
          Party to perform acts or refrain from taking any action.

1.2      Continuing Guaranty.

     (a)  The  Obligations   under  this  Guaranty  are  continuing,   absolute,
          unconditional   and   irrevocable   irrespective   of  the   validity,
          regularity,  enforceability  or  value of any of the  Obligations  and
          notwithstanding  any  claim,  defense  or right of  set-off  which the
          Guarantors  may have  against the Secured  Party,  including  any such
          claim,  defense or right based on any present or future applicable law
          and  irrespective  of any other  circumstances  which might  otherwise
          constitute  a legal or  equitable  release,  defense or discharge of a
          surety  or  a  guarantor.  Without  limiting  the  generality  of  the
          foregoing,  the  Obligations of each Guarantor  hereunder shall not be
          discharged or impaired or otherwise affected by:

          (i)  any rescission, waiver, amendment or modification of any terms or
               provisions of the  Obligations  or the documents  evidencing  the
               same.

          (ii) any fraudulent,  illegal, or improper act by any Guarantor or any
               failure,  omission  or  delay  on the  part of any  Guarantor  to
               conform  or comply  with any term of the  Obligations  or of this
               Guaranty;

          (iii) any failure of the Secured  Party to assert a claim or demand or
               to enforce or exercise any right or remedy  against any Guarantor
               or any other guarantor for any reason;

          (iv) any release or  discharge by operation of law or otherwise of any
               Guarantor  from any  Obligation or the documents  evidencing  the
               same;

          (v)  any  change  in the  existence,  structure  or  ownership  of any
               Guarantor or the legal incapacity of any Guarantor;

          (vi) any   insolvency,   bankruptcy,   reorganization,    arrangement,
               readjustment,   composition,   liquidation   or   other   similar
               proceeding  affecting  any  Guarantor  or  its/his  assets or any
               resulting  disallowance,  release  or  discharge  of  all  or any
               portion of the Obligations;

          (vii) the failure by any  Guarantor  or any other  person to sign this
               Guaranty; and

          (viii) any other occurrence, circumstance, happening or event, whether
               similar or dissimilar  to the  foregoing and whether  foreseen or
               unforeseen, which otherwise might constitute a legal or equitable
               defense or discharge of the  liabilities of a guarantor or surety
               or which otherwise might limit recourse against any Guarantor.

     (b)  This Guaranty shall continue to be effective or be reinstated,  as the
          case may be, if at any time payment or performance of the Obligations,
          or any  part  thereof,  to the  Secured  Party  is  rescinded  or must
          otherwise  be  returned  by the  Secured  Party  upon the  insolvency,
          bankruptcy or  reorganization  of the  Guarantors,  all as though such
          payment to the Secured Party has not been made.

1.3      Guaranty of Payment and Not of Collection; Subordination.

     (a)  The  liability  of each  Guarantor  shall be  continuing,  direct  and
          immediate and not conditional or contingent upon either the pursuit of
          any remedies against the Companies, a Guarantor or any other person or
          foreclosure  of any  security  interests  or  liens  available  to the
          Secured Party, its successors, endorsees or assigns. The Secured Party
          may accept  any  payment(s),  plan for  adjustment  of debts,  plan of
          reorganization  or  liquidation,  or plan of  composition or extension
          proposed  by, or on behalf of, the  Companies  or any other  Guarantor
          without in any way  affecting  or  discharging  the  liability  of any
          Guarantor. If the Obligations are partially paid, each Guarantor shall
          remain liable for any balance of such  Obligations.  Without  limiting
          any other  provision of,  impairing or affecting  this  Guaranty,  the
          Secured Party may, at any time and from time to time,  take or refrain
          from taking,  all or any actions  whatsoever,  including the following
          actions:  (a) retain or obtain a Lien in any property to secure any of
          the Obligations;  (b) amend,  extend,  renew, adjust, waive or release
          any  Obligations or the terms thereof,  (c) release or fail to perfect
          its interest in all or any property securing any of the Obligations or
          permit any substitution or exchange for any such property.

     (b)  With respect to any sum paid or payable by a Guarantor hereunder or in
          connection herewith or otherwise, all rights of such Guarantor against
          any other  Guarantor  arising  as a result  thereof by way of right of
          subrogation, contribution, reimbursement, indemnity or otherwise shall
          in all respects be  subordinate  and junior in right of payment to the
          prior  indefeasible   payment  or  performance  in  full  of  all  the
          Obligations.  In addition,  any  indebtedness  of any Guarantor now or
          hereafter  held by any  Guarantor is hereby  subordinated  in right of
          payment to the prior payment or performance in full of the Obligations
          and no  Guarantor  shall  demand,  sue for,  or  otherwise  attempt to
          collect any such indebtedness,  or prove any claim in competition with
          the Secured Party in respect of any payment hereunder in bankruptcy or
          insolvency  proceedings of any nature. If any amount shall erroneously
          be  paid  to  any  Guarantor  on  account  of  (i)  such  subrogation,
          contribution,  reimbursement,  indemnity or similar  right or (ii) any
          such  indebtedness  of any Guarantor as borrower of a Guarantor,  such
          amount shall be held in trust for the benefit of the Secured Party and
          shall  forthwith be paid to the Secured  Party to be credited  against
          the payment of the Obligations.

1.4  Discharge.  Each Guarantor covenants and agrees that this Guaranty will not
     be discharged, except by complete performance of the Obligations.

1.5  Interest.  Guarantors will pay on demand interest on all amounts due to the
     Secured  Party  under  this  Guaranty,  or  arising  under  any  documents,
     instruments,  or  agreements  relating  to  any  collateral  securing  this
     Guaranty,  from the time the Secured  Party first  demands  payment of this
     Guaranty  at a rate  equal to the  highest  rate  applicable  to any of the
     Obligations after the earlier of (i) demand, or (ii) maturity, or (iii) the
     occurrence  of any event of  default  under  any  instrument,  document  or
     agreement  evidencing  the  Obligations  (but in no event  higher  than the
     highest rate of interest which under the circumstances may be charged under
     applicable law).

1.6  Costs and  Expenses.  Without  limiting  any  obligation  of any  Guarantor
     hereunder,  each  Guarantor  agrees,  jointly  and  severally,  to pay  all
     reasonable  fees  and  costs  (including,  without  limitation,  reasonable
     attorneys' fees and expenses,  whether or not involving  litigation  and/or
     appellate  or  bankruptcy  proceedings)  incurred  by Secured  Party in (i)
     collecting  or securing or attempting to collect or secure this Guaranty or
     each  Convertible  Debenture;  (ii) defending or prosecuting any actions or
     proceedings arising out of or relating to the Secured Party's  transactions
     with the Guarantors.

1.7  Indemnification.  For said good and valuable consideration,  the Guarantors
     also shall  indemnify,  defend,  and hold the Secured Party,  or any agent,
     employee,  officer,  attorney,  or  representative  of the  Secured  Party,
     harmless of and from any claim  brought or  threatened  against the Secured
     Party or any such  person  so  indemnified  by:  any  Guarantor;  any other
     obligor or endorser of the Obligations or any other person (as well as from
     attorneys'  fees and expenses in  connection  therewith)  on account of the
     Secured Party's  relationship with the Guarantors,  or any other obligor or
     endorser of the  Obligations  (each of which may be defended,  compromised,
     settled,  or  pursued by the  Secured  Party  with  counsel of the  Secured
     Party's selection, but at the expense of the undersigned).

SECTION 2         Additional Guarantors.

     Pursuant to Section 6.12 of the Security Agreement,  each subsidiary of the
Guarantors  that is formed or acquired  after the  execution of this Guaranty is
required to execute  the  Guaranty.  Such  subsidiary  shall  become a Guarantor
hereunder  with the same force and effect as if originally  named as a Guarantor
herein.  The  execution  and  delivery of any  instrument  adding an  additional
Guarantor as a party to this Guaranty shall not require the consent of any other
Guarantor  hereunder.  The rights and  obligations of each  Guarantor  hereunder
shall  remain in full force and effect  notwithstanding  the addition of any new
Guarantor as a party to this Guaranty.

SECTION 3         Representations and Warranties.

     Each  Guarantor  hereby  represents  and  warrants to the Secured  Party as
follows:

     (a)  each corporate  Guarantor has full power, right and authority to enter
          into  and  perform  its  obligations  under  this  Guaranty,  and this
          Guaranty has been duly  executed and  delivered by each  Guarantor and
          constitutes the valid and binding  obligation of each Guarantor and is
          enforceable against each Guarantor in accordance with its terms.

     (b)  No  permits,  approvals  or consents  of or  notifications  to (a) any
          governmental  entities,  or (b) any  other  persons  or  entities  are
          necessary in connection  with the execution,  delivery and performance
          by any  Guarantor  of  this  Guaranty  and  the  consummation  by each
          Guarantor of the transactions contemplated hereby.

     (c)  Neither the  execution  and delivery of this Guaranty by any Guarantor
          nor the performance by them of the  transactions  contemplated  hereby
          will:

          (i)  violate or conflict  with or result in a breach of any  provision
               of any law, statute, rule, regulation,  order, permit,  judgment,
               ruling,  injunction,  decree  or other  decision  of any court or
               other tribunal or any governmental  entity or agency binding on a
               Guarantor or his  properties,  or conflict with or cause an event
               of default under any contract or agreement of a Guarantor; or

          (ii) require any authorization,  consent, approval, exemption or other
               action by or notice to any court,  administrative or governmental
               body, person, entity or any other third party.

     (d)  Each of the  Companies  is  solvent,  able to pay  its  debts  as they
          mature, has capital sufficient to carry on its business,  and the fair
          present  saleable  value of its assets,  calculated on a going concern
          basis,  is in excess  of the  amount of its  liabilities  (except  for
          certain derivative liabilities related to the Convertible Debentures).

     (e)  Except as set forth on Schedule 3(e),  the Guarantors  have no pending
          or threatened litigation, arbitration, actions or proceedings which if
          adversely decided could reasonably be expected to result in a Material
          Adverse Effect, individually or in the aggregate.

     (f)  The Parent is not engaged in any business or activity and does not own
          any asset or property other than (a) the direct or indirect  ownership
          of all  outstanding  equity  interests in the  subsidiaries  listed in
          Schedule 6.12 of the Security Agreement and pledged pursuant to Pledge
          Agreement,  (b) maintaining its corporate existence, (c) participating
          in tax, accounting and other  administrative  activities as the parent
          of the consolidated group of companies, (d) the execution and delivery
          of  the  Transaction  Documents  to  which  it  is  a  party  and  the
          performance  of  its  obligations   thereunder,   and  (e)  activities
          incidental to the  businesses  or activities  described in clauses (a)
          through (d) of this Section 3(f).

SECTION 4.        Event of Default.

     (a)  For purposes of this Guaranty,  an event of default shall be deemed to
          have occurred upon an Event of Default under the Security Agreement.

     (b)  Upon an event of default,  all of the  obligations  of each  Guarantor
          hereunder  shall be immediately  due and payable without any action on
          the part of the Secured Party, and the Secured Party shall be entitled
          to seek and institute any and all remedies available to it.

SECTION 5         Remedies, Other Obligations, Breaches and Injunctive Relief.

     (a)  No remedy  conferred  under this  Guaranty  upon the Secured  Party is
          intended to be exclusive of any other remedy  available to the Secured
          Party, pursuant to the terms of this Guaranty or otherwise,  at law or
          in equity  (including  a decree of specific  performance  and/or other
          injunctive relief). No single or partial exercise by the Secured Party
          of any right,  power or remedy  hereunder  shall preclude any other or
          further exercise thereof.

     (b)  The failure of the Secured Party to exercise any right or remedy under
          this  Guaranty  or  otherwise,  or delay in  exercising  such right or
          remedy, shall not operate as a waiver thereof.

     (c)  Every right and remedy of the Guarantors  under any document  executed
          in connection with this transaction, including but not limited to this
          Guaranty, the Loan Instruments,  and the Other Loan Documents or under
          applicable  law may be exercised from time to time and as often as may
          be deemed expedient by the Secured Party.

     (d)  The  Guarantors  acknowledge  that a breach by a Guarantor  of its/his
          obligations hereunder will cause irreparable harm to the Secured Party
          and that the remedy at law for any such breach may be inadequate.  The
          Guarantors  therefore  agree that,  in the event of any such breach or
          threatened  breach  by the  Guarantors,  the  Secured  Party  shall be
          entitled,   in  addition  to  all  other  available  remedies,  to  an
          injunction  restraining any breach, and specific  performance  without
          the  necessity of showing  economic loss and without any bond or other
          security being  required.  Nothing herein shall limit Secured  Party's
          right to pursue  actual  damages  for any  failure by a  Guarantor  to
          comply with the terms of this Guaranty.

SECTION 6         Maximum Liability.

     Notwithstanding  any  provision  herein  contained  to the  contrary,  each
Guarantor's  liability  under this Guaranty shall be limited to an amount not to
exceed as of any date of determination  the amount which could be claimed by any
Secured Party from such  Guarantor  under this Guaranty  without  rendering such
claim voidable or avoidable  under Section 548 of the Bankruptcy Code (11 U.S.C.
ss.ss.  101 et seq.) or under any applicable state Uniform  Fraudulent  Transfer
Act,  Uniform  Fraudulent  Conveyance Act or similar  statute or common law (the
"Avoidance  Provisions")  after taking into account,  among other  things,  such
Guarantor's right of contribution and indemnification from each other Guarantor,
if any. To the end set forth above,  but only to the extent that the Obligations
of a Guarantor hereunder (the "Guaranty Obligations") would otherwise be subject
to avoidance under the Avoidance Provisions,  if such Guarantor is not deemed to
have  received  valuable  consideration,   fair  value,  fair  consideration  or
reasonably  equivalent  value for the Guaranty  Obligations,  or if the Guaranty
Obligations would render such Guarantor insolvent,  or leave such Guarantor with
an unreasonably  small capital to conduct its business,  or cause such Guarantor
to have incurred  debts (or to have intended to have incurred  debts) beyond its
ability to pay such debts as they mature, in each case as of the time any of the
Guaranty  Obligations  is deemed to have been  incurred  for the purposes of the
Avoidance Provisions,  the maximum Guaranty Obligations for which such Guarantor
shall be liable  hereunder  shall be reduced to that amount which,  after giving
effect thereto,  would not cause the Guaranty  Obligations as so reduced,  to be
subject to avoidance under the Avoidance Provisions.

SECTION 7         Miscellaneous.

7.1  Notices,   Consents,   etc.  Any  notices,   consents,   waivers  or  other

7.3  Severability. If any provision of this Guaranty is, for any reason, invalid
     or   unenforceable,   the  remaining   provisions  of  this  Guaranty  will
     nevertheless  be valid and  enforceable  and will  remain in full force and
     effect.   Any   provision  of  this   Guaranty  that  is  held  invalid  or

     will remain in full force and effect.

7.4  Amendment  and Waiver.  This  Guaranty may be amended,  or any provision of

     will be binding on a party  hereto only if such  amendment or waiver is set
     forth in a writing  executed by the parties hereto.  The waiver by any such
     party  hereto  of a breach  of any  provision  of this  Guaranty  shall not
     operate or be construed as a waiver of any other breach.

7.5  Headings.  The subject  headings of Articles and Sections of this  Guaranty
     are  included  for  purposes of  convenience  only and shall not affect the
     construction or interpretation of any of its provisions.

7.6  Assignment.  This Guaranty will be binding upon and inure to the benefit of
     the parties hereto and their respective  successors and permitted  assigns,
     but will not be  assignable  or  delegable  by the  Guarantors.  Except  as
     otherwise provided herein, this Note shall bind and inure to the benefit of
     and be  enforceable  by the  parties  and their  permitted  successors  and
     assigns.

7.7  Further  Assurances.  Each party will execute all  documents  and take such
     other  actions  as the other  parties  may  reasonably  request in order to

     construed  to confer  upon or give to any person or entity,  other than the
     stated  beneficiaries  of this  Guaranty  and  their  respective  permitted
     successors  and assigns,  any rights or remedies under or by reason of this
     Guaranty.

7.9  Liability  of  Guarantors.   Notwithstanding   any  provision  herein,  the

     obligation of the Guarantors or of any of them).

7.10 No Strict  Construction.  The language used in this Guaranty will be deemed
     to be the  language  chosen by the parties  hereto to express  their mutual
     intent,  and no rule of strict  construction  will be applied  against  any
     party hereto.

7.11 Governing  Law;  Jurisdiction.  This  Guaranty  shall  be  governed  by and
     interpreted in accordance  with the laws of the State of New Jersey without
     regard to the  principles  of conflict of laws.  The parties  further agree
     that any action between them shall be heard in Hudson  County,  New Jersey,
     and expressly  consent to the  jurisdiction and venue of the Superior Court
     of New  Jersey,  sitting in Hudson  County and the United  States  District
     Court for the District of New Jersey sitting in Newark,  New Jersey for the
     adjudication  of any civil  action  asserted  pursuant  to this  Paragraph,
     provided, however, that nothing herein shall prevent the Secured Party from
     enforcing its rights and remedies (including, without limitation, by filing
     a civil action) with respect to the Collateral and/or the Guarantors in any
     other  jurisdiction  in which the  Collateral  and/or the Guarantors may be
     located.  Each party hereby  irrevocably waives personal service of process
     and consents to process being served in any such suit, action or proceeding
     by mailing a copy  thereof to such party at the address for such notices to
     it under this Guaranty and agrees that such service shall  constitute  good
     and sufficient  service of process and notice  thereof.  Nothing  contained
     herein  shall be deemed to limit in any way any right to serve  process  in
     any manner permitted by law.

7.12 Waiver of Jury Trial.  AS A MATERIAL  INDUCEMENT  FOR THE SECURED  PARTY TO
     MAKE  FINANCIAL  ACCOMMODATIONS  TO THE  COMPANIES OR ANY  GUARANTOR,  EACH
     GUARANTOR HEREBY WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW,
     ANY RIGHT IT MAY HAVE TO TRIAL BY JURY IN ANY LEGAL  PROCEEDING  RELATED IN
     ANY  WAY TO  THIS  GUARANTY  AND/OR  ANY  AND  ALL OF THE  OTHER  DOCUMENTS
     ASSOCIATED WITH THIS TRANSACTION.

7.13 Counterparts;  Facsimile  Signatures.  This  Guaranty  may be executed  and
     delivered by exchange of facsimile  signatures of the Secured Party and the
     Guarantors, and those signatures need not be affixed to the same copy. This
     Guaranty may be executed in any number of counterparts.

7.14 Entire  Agreement.  This Guaranty  (including the recitals  hereto) and the
     other  documents or agreements  delivered in connection  herewith set forth
     the entire  understanding of the parties with respect to the subject matter
     hereof,  and shall not be  modified  or  affected  by any offer,  proposal,
     statement or representation,  oral or written,  made by or for any party in
     connection  with the  negotiation of the terms hereof,  and may be modified
     only by instruments signed by all of the parties hereto.

7.15 Collateral.  The  Guarantors'  obligations  to the Secured Party  hereunder
     shall be secured by all collateral  heretofore or hereafter  granted to the
     Secured Party by the  Guarantors,  whether in connection with this Guaranty
     or otherwise,  including, without limitation, all collateral granted to the
     Secured Party pursuant to the Security Agreement or the Pledge Agreement.

7.16 Existing Guaranty.  The Guaranty is intended to be supplemental to, and not
     in  limitation  of, any existing  guaranty in favor of the Secured Party to
     secure the  Obligations,  whether under the Prior Debt Security  Documents,
     the Other Loan Documents, or otherwise. All such existing guaranty, and any
     rights of the Secured Party in connection  therewith,  shall remain in full
     force and effect in  accordance  with  their  respective  terms,  provided,
     however,  that  in the  event  of a  conflict  between  the  terms  of this
     Agreement and of any such prior guaranty,  or the documents  evidencing the
     same, the terms of this Agreement shall control.

     IN  WITNESS  WHEREOF,  each  Guarantor  has  caused  this  Global  Guaranty
Agreement to be signed as of the date first written above.
