Item 4.   Purpose of Transaction.
          ----------------------

          On November 14, 2007, RAM notified the Company that it is not prepared
to proceed with the acquisition of the Company on the terms  contemplated by the
Merger Agreement and offered either to arrange for the payment of the negotiated
$100 million termination fee or to engage the Company in a constructive dialogue
to negotiate a transaction on revised  terms. A copy of the letter  delivered by
RAM is attached hereto as Exhibit 1 and is incorporated herein by reference.

          The  Merger  Agreement  was  negotiated  in July  2007,  when the debt
capital markets were beginning to deteriorate. Due to the resulting uncertainty,
RAM  required  that its  liability  be  limited  to $100  million,  which is the
Company's  exclusive  remedy  in  the  event  that  RAM  and  Merger  Sub do not
consummate the transaction,  and RAM agreed to a higher per share purchase price
in  consideration  for this  limitation  on  liability.  The  limited  guarantee
provided by Cerberus Partners, L.P. ("Cerberus") in favor of the Company, a copy
of which is attached hereto as Exhibit 2 and is incorporated herein by reference
(the  "Limited  Guarantee"),  in respect of RAM's and Merger  Sub's  obligations
under the Merger Agreement was similarly expressly limited to $100 million,  and
recovery  of that  amount  was  expressly  stated to be the  Company's  sole and
exclusive  remedy under the Limited  Guarantee.  The $100 million  limitation of
liability was specifically  negotiated,  was unconditional and was not dependent
on the  occurrence  of a  material  adverse  change.  As one  indication  of the
importance  to  Cerberus  of this  limitation  of  liability  under the  Limited
Guarantee,  the parties agreed that in the event that the Company challenged the
validity  of the  limitations  set forth in the Limited  Guarantee,  the Company
would forfeit its right to recover any amount under the Limited Guarantee.

          In August 2007,  as  conditions  in the capital  markets  continued to
worsen, RAM contacted the Company and its representatives and asked to engage in
a constructive  dialogue to address concerns arising out of these  developments.
The Company refused to meet or engage in this dialogue. Since that time, RAM has
been diligent in its efforts to consummate the transaction,  but has encountered
sustained  volatility in the credit markets,  which has had a variety of adverse
consequences.

          RAM  continues  to seek a  constructive  dialogue  with the Company to
negotiate a transaction on revised terms.

Attention: Roger E. Schwed, General Counsel

Re:    Agreement and Plan of Merger  among RAM Holdings,  Inc.  ("Parent"),  RAM
       Acquisition  Corp.  ("Merger Sub") and United Rentals, Inc. ("URI") dated
       as of July 22, 2007 (the "Agreement")

Dear Mr. Schwed:

          We are writing in connection with the  above-captioned  Agreement.  As
you  know,  as part  of the  negotiations  of the  Agreement  and the  ancillary
documentation,  the parties agreed that our maximum  liability in the event that
we elected  not to  consummate  the  transaction  would be payment of the Parent
Termination  Fee (as defined in the  Agreement)  in the amount of $100  million.
This aspect of the transaction is memorialized  in, among other places,  Section
8.2(e) of the Agreement, the final sentence of which reads as follows:

          "In  no  event,  whether  or not  this  Agreement  has  been
          terminated  pursuant to any provision hereof,  shall Parent,
          Merger Sub, Guarantor or the Parent Related Entities, either
          individually  or  in  the  aggregate,   be  subject  to  any
          liability  in excess  of the  Parent  Termination  Fee [$100
          Million]  for any or all  losses or damages  relating  to or
          arising   out  of  this   Agreement   or  the   transactions
          contemplated by this Agreement, including breaches by Parent
          or Merger Sub of any representations,  warranties, covenants
          or agreements  contained in this Agreement,  and in no event
          shall the Company seek  equitable  relief or seek to recover
          any money  damages  in excess of such  amount  from  Parent,
          Merger Sub,  Guarantor or any Parent Related Party or any of
          their respective Representatives."

          In light  of the  foregoing,  and  after  giving  the  matter  careful
consideration,  this is to advise that Parent and Merger Sub are not prepared to
proceed with the acquisition of URI on the terms contemplated by the Agreement.





          Given this  position  and the rights and  obligations  of the  parties
under the Agreement and the ancillary  documentation,  we see two paths forward.
If URI is interested in exploring a transaction between our companies on revised
terms,  we would be happy to  engage  in a  constructive  dialogue  with you and
representatives  of your  choosing  at your  earliest  convenience.  We could be
available to meet in person or telephonically  with URI and its  representatives
for this  purpose  immediately.  In order to pursue this path,  we would need to
reach resolution on revised terms within a matter of days.

          If, however,  you are not interested in pursuing such discussions,  we
are prepared to make arrangements, subject to appropriate documentation, for the
payment of the $100 million Parent Termination Fee.

          We look forward to your response.

                                              Very truly yours,


                                              RAM HOLDINGS, INC.

Confidential

                           LIMITED GUARANTEE

          Limited   Guarantee,   dated  as  of  July  22,  2007  (this  "Limited
Guarantee"),  by Cerberus  Partners,  L.P. (the  "Guarantor") in favor of United
Rentals, Inc., a Delaware corporation (the "Company").  Reference is hereby made
to the  Agreement and Plan of Merger (the "Merger  Agreement"),  dated as of the
date hereof, among RAM Holdings,  Inc., a Delaware corporation  ("Parent"),  RAM
Acquisition Corp., a Delaware  corporation and a direct wholly-owned  subsidiary
of Parent  ("Merger Sub"),  and the Company.  Capitalized  terms,  and terms not
capitalized  but which are  nonetheless  defined  in  Section  9.3 of the Merger
Agreement, which are used herein but not otherwise defined herein shall have the
meanings ascribed to them in the Merger Agreement.

          1.  Limited Guarantee.

          (a) To induce the  Company to enter  into the  Merger  Agreement,  the
Guarantor hereby absolutely,  irrevocably and unconditionally  guarantees to the
Company,  but only up to the  Maximum  Amount (as  defined  below),  the due and
punctual  payment by Parent and Merger Sub,  as and when due,  of their  payment
obligations   under  the  last  two  sentences  of  Section   6.10(d),   Section
6.11(d)-(f),  Section  8.2(c),  Section  8.2(d)  and  Section  8.3 of the Merger
Agreement (collectively,  the "Guaranteed  Obligations").  The maximum aggregate
liability of the Guarantor in respect of the  Guaranteed  Obligations  shall not
exceed  $100,000,000  plus any obligations of Parent to pay reasonable costs and
expenses and interest under Section 8.2(d) of the Merger Agreement (the "Maximum
Amount"),  and the Company hereby agrees that this Limited  Guarantee may not be
enforced without giving effect to the Maximum Amount.

          (b) Notwithstanding anything to the contrary contained in this Limited
Guarantee,  but subject to the last sentence of Section 2(d) hereof, the Company
hereby  agrees that to the extent  Parent and Merger Sub are  relieved of all or
any  portion  of the  Guaranteed  Obligations  by the  satisfaction  thereof  or
pursuant  to any  agreement  with the  Company  (any  amount  so  relieved,  the
"Reduction  Amount"),  the Maximum Amount shall be reduced by an amount equal to
the Reduction  Amount.  All payments  hereunder shall be made in lawful money of
the United States, in immediately available funds.

          2.  Terms of Limited Guarantee.

          (a) This Limited  Guarantee is an unconditional  guarantee of payment,
not  collection,  and a separate action or actions may be brought and prosecuted
against  the  Guarantor  to enforce  this  Limited  Guarantee  up to the Maximum
Amount,  irrespective  of whether any action is brought against Parent or Merger
Sub or any other Person or whether  Parent or Merger Sub or any other Person are
joined in any such action or actions.

          (b) The liability of the Guarantor under this Limited Guarantee (up to
the Maximum Amount) shall, to the fullest extent permitted under applicable law,
be absolute,  irrevocable and  unconditional in accordance with the terms hereof
irrespective of:





                    (i) the failure of the Company to assert any claim or demand
          or  enforce  any right or remedy  against  Parent or Merger Sub or any
          other  Person  primarily  or  secondarily  liable with  respect to any
          Guaranteed Obligation;

                    (ii) the validity or enforceability of the Merger Agreement,
          but only to the extent  resulting from any lack of corporate  power or
          authority of Parent or Merger Sub;

                    (iii) the addition, substitution or release of any Person as
          a guarantor of the Guaranteed Obligations;

                    (iv) any release or discharge of any obligation of Parent or
          Merger Sub contained in the Merger Agreement resulting from any change
          in the corporate existence, structure or ownership of Parent or Merger
          Sub or any other Person  primarily or secondarily  liable with respect
          to  any  Guaranteed   Obligation,   or  any  insolvency,   bankruptcy,
          reorganization or other similar proceeding  affecting Parent or Merger
          Sub or any other Person  primarily or secondarily  liable with respect
          to any Guaranteed Obligation or any of their respective assets;

                    (v) any  change  in the  time,  manner,  place  or  terms of
          payment, or any change or extension of the time of payment of, renewal
          or alteration of, any Guaranteed Obligation, any escrow arrangement or
          other security therefor, any liability incurred directly or indirectly
          in  respect  thereof,  or  any  amendment,   rescission,   compromise,
          consolidation  or waiver of, or any consent to any departure  from the
          terms of,  the  Merger  Agreement  or the  documents  entered  into in
          connection therewith;

                    (vi) the existence of any claim, set-off or other right that
          the Guarantor may have at any time against  Parent,  Merger Sub or the
          Company,  whether in  connection  with any  Guaranteed  Obligation  or
          otherwise; or

                    (vii) the  adequacy  of any other means the Company may have
          of obtaining repayment of any of the Guaranteed Obligations.

          (c) To the fullest  extent  permitted  by law,  the  Guarantor  hereby
irrevocably  and  expressly  waives  any and all rights or  defenses  arising by
reason of any law which would otherwise  require any election of remedies by the
Company.  The  Guarantor  hereby  waives  any and all  notice  of the  creation,
renewal, extension or accrual of any of the Guaranteed Obligations and notice of
or proof of reliance by the Company upon this Limited Guarantee or acceptance of
this Limited Guarantee (except for notices provided to Parent in accordance with
Section 9.2 of the Merger Agreement).  The Guaranteed  Obligations,  and each of





them, shall conclusively be deemed to have been created,  contracted or incurred
in reliance upon this Limited Guarantee, and all dealings between Parent, Merger
Sub or the  Guarantor,  on the one hand,  and the Company,  on the other,  shall
likewise be  conclusively  presumed to have been had or  consummated in reliance
upon this Limited  Guarantee.  When  pursuing its rights and remedies  hereunder
against the  Guarantor,  the Company shall be under no obligation to pursue such
rights and remedies it may have against Parent or Merger Sub or any other Person
for the Guaranteed  Obligations or any right of offset with respect thereto, and
any failure by the Company to pursue such other rights or remedies or to collect
any  payments  from Parent or Merger Sub or any such other  Person or to realize
upon or to exercise any such right of offset,  and any release by the Company of
any right of offset, shall not relieve the Guarantor of any liability hereunder,
and shall not impair or affect the rights and remedies, whether express, implied
or available as a matter of law, of the Company.

          (d) The Company  shall not be obligated to file any claim  relating to
any Guaranteed Obligation in the event that Parent or Merger Sub becomes subject
to a bankruptcy,  reorganization or similar  proceeding,  and the failure of the
Company to so file shall not affect the Guarantor's  obligations  hereunder.  In
the  event  that  any  payment  to the  Company  in  respect  of any  Guaranteed
Obligation  is  rescinded  and/or  returned  to the  Guarantor  for  any  reason
whatsoever,  the  Guarantor  shall remain liable  hereunder  with respect to the
Guaranteed  Obligation as if such payment had not been made; provided,  however,
that in the event that any payment to the  Company in respect of any  Guaranteed
Obligation is rescinded and/or returned to the Parent for any reason whatsoever,
this Guarantee  shall not continue to be effective or be reinstated with respect
to any such  payments  made by Guarantor and  subsequently  so rescinded  and/or
returned.

          (e) The  Guarantor  agrees  that the  Company may at any time and from
time to time, without notice to or further consent of the Guarantor,  extend the
time of payment of any  Guaranteed  Obligation,  and may also make any agreement
with Parent, Merger Sub or any Person liable for any Guaranteed Obligation,  for
the extension,  renewal, payment,  compromise,  discharge or release thereof, in
whole  or in  part,  or for any  modification  of the  terms  thereof  or of any
agreement  between the Company and Parent,  Merger Sub or any such other  Person
without in any way impairing or affecting the Guarantor's obligations under this
Limited Guarantee.

          3.  Waiver of Acceptance,  Presentment;  Etc.  To the  fullest  extent
permitted by law, the Guarantor  hereby  expressly  waives any and all rights or
defenses arising by reason of any law which would otherwise require any election
of remedies by the Company. The Guarantor waives promptness,  diligence,  notice
of the acceptance of this Limited  Guarantee and of any Guaranteed  Obligations,
presentment,  demand for payment, notice of non-performance,  default,  dishonor
and protest, notice of the incurrence of any Guaranteed Obligation and all other
notices of any kind (except for notices  provided to Parent in  accordance  with
Section 9.2 of the Merger  Agreement),  all  defenses  which may be available by
virtue  of any  valuation,  stay,  moratorium  law or other  similar  law now or
hereafter in effect,  any right to require the  marshalling of assets of Parent,
Merger Sub or any other Person  interested in the  transactions  contemplated by
the Merger Agreement,  and all suretyship  defenses  generally (other than fraud
and willful misconduct by the Company or any of its affiliates,  defenses to the
payment of the Guaranteed  Obligations  under the Merger  Agreement or breach by
the Company of this Limited Guarantee).  Notwithstanding the foregoing,  for the
avoidance of doubt, Guarantor retains any and all defenses that may be available
to it  that  the  Guaranteed  Obligations  are not due  pursuant  to the  Merger
Agreement and/or have already been satisfied or performed.





          4. No Recourse. The Company, by its acceptance of the benefits hereof,
acknowledges as follows:

          (a) The Company acknowledges that the sole assets of Parent and Merger
Sub are cash in a de minimis  amount and its rights under the Merger  Agreement,
and that no additional  funds are expected to be contributed to Parent or Merger
Sub unless and until the Closing occurs.  The Company,  by its acceptance of the
benefits  hereof,  agrees that it has no right of recovery in respect of a claim
arising  under the Merger  Agreement  or in  connection  with any  documents  or
instruments delivered in connection therewith, including this Limited Guarantee,
against any former,  current or future officer,  agent, affiliate or employee of
the Guarantor or Parent (or any of their  successors' or permitted  assignees'),
against  any former,  current or future  general or limited  partner,  member or
stockholder of the Guarantor or Parent (or any of their successors' or permitted
assignees'),  notwithstanding that Guarantor is or may be a partnership,  or any
affiliate  thereof or against any former,  current or future director,  officer,
agent, employee, affiliate, general or limited partner, stockholder,  manager or
member of any of the foregoing (collectively,  "Guarantor/Parent Affiliates"; it
being understood that the term Guarantor/Parent Affiliates shall not include the
Guarantor,  Parent or Merger Sub),  whether by or through attempted  piercing of
the  corporate  veil,  by or through a claim by or on behalf of Parent or Merger
Sub against the Guarantor/Parent Affiliates, or otherwise, except for its rights
under  this  Limited  Guarantee  and  subject to the  limits  contained  herein;
provided,  however,  that in the event the  Guarantor (i)  consolidates  with or
merges with any other Person (an  "Acquiring  Person") and is not the continuing
or surviving entity of such consolidation or merger or (ii) transfers or conveys
all or substantially  all of its properties and other assets to any Person (also
an "Acquiring Person") such that the sum of the Guarantor's remaining net assets
plus uncalled  capital is less than the Maximum  Amount,  then, and in each such
case, the Company may seek recourse from such Acquiring  Person (in either case,
a  "Successor  Entity"),  as the case  may be,  but  only to the  extent  of the
liability of the Guarantor hereunder.

          (b) Recourse against the Guarantor under this Limited  Guarantee shall
be the  sole and  exclusive  remedy  of the  Company  and all of its  affiliates
against the  Guarantor  and any  Guarantor/Parent  Affiliates  in respect of any
liabilities or  obligations  arising  under,  or in connection  with, the Merger
Agreement or the transactions contemplated thereby including in the event Parent
or Merger Sub breaches any covenant, representation or warranty under the Merger
Agreement  or the  Guarantor  breaches a  covenant,  representation  or warranty
hereunder.  The Company hereby covenants and agrees that it shall not institute,
and shall cause its controlled  affiliates  not to institute,  any proceeding or
bring any other claim arising under, or in connection with, the Merger Agreement
or  the  transactions   contemplated  thereby,  against  the  Guarantor  or  any
Guarantor/Parent  Affiliates  except for claims against the Guarantor under this
Limited  Guarantee.  Nothing set forth in this Limited Guarantee shall affect or
be construed  to affect any  liability of Parent or Merger Sub to the Company or
shall confer or give or shall be construed to confer or give to any Person other
than the Company any rights or remedies against any Person other than the rights
of the Company against the Guarantor as expressly set forth herein.





          (c) The Company  acknowledges  that the Guarantor is agreeing to enter
into this  Limited  Guarantee  in reliance on the  provisions  set forth in this
Section 4. This Section 4 shall survive termination of this Limited Guarantee.

          5.  No  Subrogation.   The  Guarantor   hereby   unconditionally   and
irrevocably  agrees not to exercise any rights that it may now have or hereafter
acquire  against  Parent,  Merger Sub or any other Person liable with respect to
any of the  Guaranteed  Obligations  that  arise  from the  existence,  payment,
performance or enforcement of the Guarantor's  obligation under or in respect of
this  Limited  Guarantee  or  any  other  agreement  in  connection   therewith,
including,   without  limitation,  any  right  of  subrogation,   reimbursement,
exoneration, contribution or indemnification and any right to participate in any
claim or remedy of the Company against Parent,  Merger Sub or such other Person,
whether or not such claim,  remedy or right arises in equity or under  contract,
statute  or common  law,  including,  without  limitation,  the right to take or
receive from Parent, Merger Sub or such other Person, directly or indirectly, in
cash or other property or by set-off or in any other manner, payment or security
on  account of such  claim,  remedy or right,  unless  and until the  Guaranteed
Obligations  and any  other  amounts  that may be  payable  under  this  Limited
Guarantee  shall have been paid in full in cash.  If any amount shall be paid to
the  Guarantor in violation of the  immediately  preceding  sentence at any time
prior to the payment in full in cash of the Guaranteed Obligations and any other
amounts that may be payable under this Limited  Guarantee,  such amount shall be
received and held in trust for the benefit of the Company,  shall be  segregated
from other  property and funds of the Guarantor  and shall  forthwith be paid or
delivered  to the  Company in the same form as so received  (with any  necessary
endorsement  or  assignment)  to be  credited  and  applied  to  the  Guaranteed
Obligations  and any  other  amounts  that may be  payable  under  this  Limited
Guarantee,  in accordance  with the terms of the Merger  Agreement and herewith,
whether  matured or unmatured,  or to be held as collateral  for the  Guaranteed
Obligations  or other amounts  payable under this Limited  Guarantee  thereafter
arising.

          6.  Termination.  This  Limited  Guarantee  shall  terminate  and  the
Guarantor shall have no further  obligations  under this Limited Guarantee as of
the earliest to occur of (a) the  Effective  Time,  (b) the  termination  of the
Merger  Agreement in accordance  with its terms by mutual consent of the parties
or under other circumstances in which neither the Parent nor Merger Sub would be
obligated to make any payments under the last two sentences of Section  6.10(d),
Section  6.11(d) - (f),  Section  8.2(c),  Section  8.2(d) or Section 8.3 of the
Merger Agreement and (c) the first  anniversary of any termination of the Merger
Agreement in accordance with its terms,  except as to a claim for payment of any
Guaranteed  Obligation  presented  by the  Company to Parent,  Merger Sub or the
Guarantor by such first anniversary. In the event that the Company or any of its
subsidiaries  asserts in any litigation  relating to this Limited Guarantee that
the  provisions of Section 1 hereof  limiting the  Guarantor's  liability to the
Maximum Amount or that the  provisions of Section 4 hereof are illegal,  invalid
or unenforceable in whole or in part, (i) the obligations of the Guarantor under
this Limited  Guarantee  shall  terminate in all respects and shall thereupon be
null and void and (ii) if the Guarantor has  previously  made any payments under
this Limited  Guarantee it shall be entitled to have such  payments  refunded by
the Company.





          7. Continuing Guarantee.  Unless terminated pursuant to the provisions
of Section 6 hereof, this Limited Guarantee is a continuing one and shall remain
in full force and effect until the indefeasible payment and satisfaction in full
of the Guaranteed  Obligations up to the Maximum Amount (as such obligations may
be modified pursuant to first sentence of Section 1(b) hereof), shall be binding
upon the Guarantor,  its successors and assigns,  and shall inure to the benefit
of,  and  be  enforceable  by,  the  Company  and  its  respective   successors,
transferees and assigns. All obligations to which this Limited Guarantee applies
or may apply under the terms hereof shall be conclusively  presumed to have been
created in reliance hereon.  Subject to Section 4 hereof,  each and every right,
remedy and power  hereby  granted to the  Company  shall be  cumulative  and not
exclusive of any other,  and may be exercised by the Company at any time or from
time to time.  The Company shall not have any  obligation to proceed at any time
or in any manner against, or exhaust any or all of the Company's rights against,
Parent or Merger Sub prior to proceeding against the Guarantor hereunder.

          8. Entire  Agreement.  This Limited  Guarantee  constitutes the entire
agreement  with respect to the subject  matter hereof and supersedes any and all
prior discussions,  negotiations,  proposals,  undertakings,  understandings and
agreements,  whether written or oral, among Parent, Merger Sub and the Guarantor
or any of  their  affiliates  on the one  hand,  and the  Company  or any of its
affiliates on the other hand, except for the Merger Agreement.

          9. Amendments and Waivers.  No amendment or waiver of any provision of
this  Limited  Guarantee  will be valid and binding  unless it is in writing and
signed, in the case of an amendment, by the Guarantor and the Company, or in the
case of waiver,  by the party  against  whom the waiver is to be  effective.  No
waiver by any party of any  breach or  violation  of,  or  default  under,  this
Limited Guarantee,  whether  intentional or not, will be deemed to extend to any
prior or subsequent breach,  violation or default hereunder or affect in any way
any rights  arising by virtue of any prior or  subsequent  such  occurrence.  No
delay or omission  on the part of any party in  exercising  any right,  power or
remedy under this Limited Guarantee will operate as a waiver thereof.

          10. Counterparts. This Limited Guarantee may be executed and delivered
(including by facsimile  transmission) in one or more  counterparts,  and by the
different parties hereto in separate  counterparts,  each of which when executed
shall  be  deemed  to be an  original  but all of  which  taken  together  shall
constitute one and the same agreement.

          11.  Expenses.  The Guarantor  agrees to pay, and the Company,  by its
acceptance  of this  Limited  Guarantee,  agrees to pay, all  reasonable  out of
pocket expenses  (including  reasonable  fees of counsel)  incurred by the other
party in connection with any litigation  with respect to this Limited  Guarantee
if such other party prevails in such litigation.

          12.  Notices.  Any  notice  required  to be given  hereunder  shall be
sufficient if in writing,  and sent by facsimile  transmission with confirmation
(provided that any notice received by facsimile transmission or otherwise at the



addressee's  location on any  Business  Day after 5:00 p.m.  (addressee's  local

          13.  GOVERNING LAW AND VENUE; WAIVER OF JURY TRIAL.

made  through  the notice  procedures  set forth in  Section 12 hereof.  Without
limiting other means of service of process  permissible  under  applicable  law,
each of the parties hereby agrees that service of any process,  summons,  notice

Section  12  hereof  shall  be  effective  service  of  process  for any suit or
proceeding  in  connection  with  this  Limited  Guarantee  or the  transactions
contemplated hereby.

          (b) EACH OF THE PARTIES HERETO IRREVOCABLY WAIVES ANY AND ALL RIGHT TO
TRIAL BY JURY IN ANY LEGAL PROCEEDING  BETWEEN THE PARTIES HERETO ARISING OUT OF
OR RELATING TO THIS LIMITED GUARANTEE OR THE TRANSACTIONS CONTEMPLATED HEREBY.

          14.  Representations  and Warranties.  The Guarantor hereby represents
and warrants to the Company that:

          (a) it has all power and  authority  to  execute,  deliver and perform
this Limited Guarantee;

          (b) the execution,  delivery and performance of this Limited Guarantee
by the Guarantor (i) have been duly and validly  authorized  and approved by all
necessary   limited   partnership   action,   and   all   consents,   approvals,
authorizations,  permits of, filings with and notifications to, any Governmental
Entity necessary for the due execution, delivery and performance of this Limited
Guarantee by Guarantor  have been  obtained or made and all  conditions  thereof
have been duly complied with, and no other action by, and no notice to or filing
with, any  Governmental  Entity,  is required in connection  with the execution,
delivery or performance  of this Limited  Guarantee and (ii) do not and will not
(A) result in any breach or violation of, or default (with or without  notice or

termination, cancellation,  modification or acceleration of any obligation or to
the loss of any benefit  under any loan,  guarantee  of  indebtedness  or credit
agreement, note, bond, mortgage, indenture, lease, agreement,  contract, permit,
franchise, right or license binding upon Guarantor or any of its Subsidiaries or
result in the creation of any lien upon any of the properties,  assets or rights



of  Parent  or any of its  subsidiaries,  (B)  conflict  with or  result  in any
violation of any provision of the  organizational  documents of the Guarantor or
(C) conflict with or violate any applicable laws;

          (c) this  Limited  Guarantee  has been duly and validly  executed  and
delivered by it and  constitutes a valid and legally  binding  obligation of it,
enforceable against the Guarantor in accordance with its terms, except that such

conveyance,  reorganization,  moratorium  or other  similar  laws  affecting  or
relating  to  creditors'  rights  generally  and  (ii)  is  subject  to  general
principles of equity (regardless of whether considered in a proceeding in equity

effect in accordance with Section 6 hereof.

          15. No  Assignment.  Neither the  Guarantor nor the Company may assign
its rights,  interests or  obligations  hereunder to any other Person (except by
operation of law) without the prior written  consent of the Company (in the case
of an  assignment  by the  Guarantor)  or  the  Guarantor  (in  the  case  of an
assignment  by  the  Company);  provided,  however,  that  if a  portion  of the
Guarantor's  commitment  under  its  Equity  Commitment  Letter is  assigned  in
accordance  with  the  terms  thereof,  then  a  corresponding  portion  of  its
obligations  hereunder may be assigned to the same  assignee;  provided that any
such assignment will not relieve the Guarantor of its obligations hereunder.

          16. Severability. Any term or provision of this Limited Guarantee that
is invalid or unenforceable in any situation in any jurisdiction will not affect
the validity or  enforceability  of the remaining terms and provisions hereof or
the validity or  enforceability  of the offending term or provision in any other
situation or in any other  jurisdiction;  provided,  however,  that this Limited
Guarantee may not be enforced  without  giving  effect to the  limitation of the
amount payable  hereunder to the Maximum Amount provided in Section 1 hereof and
to the provisions of Sections 4 and 5 hereof.  No party hereto shall assert, and
each party  shall  cause its  respective  affiliates  not to  assert,  that this
Limited Guarantee or any part hereof is invalid, illegal or unenforceable.

          17. Headings. The headings contained in this Limited Guarantee are for
convenience  purposes  only  and  will  not in any way  affect  the  meaning  or
