                                                    -----------------
by each of the parties  signatory hereto as a "Guarantor"  (each, a "Guarantor")
in favor of the holders of the Notes (as  defined  below) from time to time (the
"Noteholders").

                                   WITNESSETH:

     WHEREAS,  Oil-Dri  Corporation  of  America,  a Delaware  corporation  (the
"Company"),  and each of the Noteholders  have heretofore  entered into the Note
Purchase  Agreement as of April 15, 1998,  as amended by the First  Amendment to
Note Purchase  Agreement  dated as of January 15, 2001 (the "First  Amendment"),
the Second  Amendment to Note Purchase  Agreement dated as of July 15, 2002 (the

of January 27, 2006 ((the "Third Amendment"); the Note Purchase Agreement, as so

Purchase  Agreement").  The Company has heretofore  issued the $25,000,000 6.55%
Senior  Notes due April 15, 2013 (the  "Notes")  pursuant  to the Note  Purchase
Agreement.

     WHEREAS, the Third Amendment requires that the Company cause each Guarantor
Subsidiary  to  execute  and  deliver  this  Guaranty  for  the  benefit  of the
Noteholders.

     NOW  THEREFORE,  for  and in  consideration  of  the  premises  and  mutual
covenants herein contained,  and for other good and valuable consideration,  the
receipt and adequacy of which are hereby acknowledged, each Guarantor, intending
to be legally bound, does hereby covenant and agree as follows:

     1. DEFINITIONS;  RECITALS. Capitalized terms that are used in this Guaranty
and not defined in this Guaranty shall have the meaning  ascribed to them in the
Note Purchase  Agreement.  The recitals in this Guaranty are  incorporated  into
this Guaranty.

     2. THE GUARANTY.

     2A. Guaranty of Payment. Each Guarantor, jointly and severally, absolutely,
unconditionally and irrevocably guarantees the full and prompt payment in United
States  currency  when due (whether at  maturity,  a stated  prepayment  date or
earlier by reason of acceleration or otherwise) and at all times thereafter,  of
all of the  indebtedness,  existing on the date  hereof or arising  from time to
time hereafter,  whether direct or indirect,  joint or several, actual, absolute
or  contingent,  matured or unmatured,  liquidated or  unliquidated,  secured or
unsecured, arising by contract, operation of law or otherwise, of the Company to
any Noteholder under or in respect of the Note Purchase Agreement and the Notes,
including, without limitation, the principal of and interest (including, without
limitation,   interest   accruing  before,   during  or  after  any  bankruptcy,
insolvency,  reorganization,  arrangement,  readjustment of debt, liquidation



or dissolution proceeding, and, if interest ceases to accrue by operation of law
by reason of any such proceeding, interest which otherwise would have accrued in
the  absence  of such  proceeding,  whether  or not  allowed  as a claim in such
proceeding) on the Notes or any Make-Whole Amount (collectively, the "Guarantied
Obligations").  This is a continuing  guaranty of payment and not of collection.
Notwithstanding the foregoing, the aggregate amount of any Guarantor's liability
under this Guaranty  shall not exceed the maximum amount that such Guarantor can
guaranty  without  violating,  or  causing  this  Guaranty  or such  Guarantor's
obligations under this Guaranty to be void, voidable or otherwise  unenforceable
under, any fraudulent  conveyance or fraudulent  transfer law, including Section
548(a)(2) of the Bankruptcy Code (as hereinafter defined).

     Upon an Event of Default,  any  Noteholder  may, at its sole  election  and
without notice,  proceed  directly and at once against any Guarantor to seek and
enforce payment of, and to collect and recover, the Guarantied  Obligations,  or
any portion  thereof,  without first proceeding  against the Company,  any other
Guarantor  or any other  Person  or  against  any  security  for the  Guarantied
Obligations  or for the  liability  of any such  other  Person or the  Guarantor
hereunder.  Each  Noteholder  shall have the  exclusive  right to determine  the
application  of  payments  and  credits,  if any, to such  Noteholder  from each
Guarantor,  the  Company or from any other  Person on account of the  Guarantied
Obligations or otherwise. This Guaranty and all covenants and agreements of each
Guarantor contained herein shall continue in full force and effect and shall not
be discharged  until such a time as all of the Guarantied  Obligations  shall be
indefeasibly paid in full in cash.

     2B. Obligations Unconditional. The obligations of each Guarantor under this
Guaranty shall be continuing,  absolute and  unconditional,  irrespective of (i)
the invalidity or unenforceability of the Note Purchase Agreement,  the Notes or
any other agreements,  documents,  certificates and instruments now or hereafter
executed or delivered by the Company or any other  Guarantor or any other Person
in connection with the Note Purchase  Agreement or any provision  thereof;  (ii)
the  absence  of any  attempt  by  any  Noteholder  to  collect  the  Guarantied
Obligations or any portion thereof from the Company,  any other Guarantor or any
other  Person or other  action to  enforce  the same;  (iii) any  failure by any
Noteholder to acquire,  perfect or maintain any security interest or lien in, or
take any steps to  preserve  its  rights  to, any  security  for the  Guarantied
Obligations  or any  portion  thereof  or for  the  liability  of any  Guarantor
hereunder  or the  liability of the  Company,  any other  Guarantor or any other
Person or any or all of the Guarantied Obligations;  (iv) any defense arising by
reason of any disability (other than a defense of payment, unless the payment on
which such defense is based was or is subsequently  invalidated,  declared to be
fraudulent or  preferential,  otherwise  avoided and/or required to be repaid to
the Company or a Guarantor, as the case may be, or the estate of any such party,
a trustee,  receiver or any other  Person  under any  bankruptcy  law,  state or
federal  law,  common law or  equitable  cause,  in which case there shall be no
defense of payment  with  respect to such  payment)  of the Company or any other
Person liable on the  Guarantied  Obligations  or any portion  thereof;  (v) any
Noteholder's election, in any proceeding instituted under Chapter 11 of Title 11
of the  Federal  Bankruptcy  Code (11 U.S.C.  ss.101 et seq.)  (the  "Bankruptcy
Code"),  of the application of Section  1111(b)(2) of the Bankruptcy  Code; (vi)
any borrowing or grant of a security  interest to any  Noteholder by the Company
as  debtor-in-possession,  or  extension  of credit,  under  Section  364 of the
Bankruptcy  Code;  (vii) the  disallowance or avoidance of all or any portion of
any Noteholder's claim(s) for repayment of the Guarantied  Obligations under the



Bankruptcy  Code  or any  similar  state  law or the  avoidance,  invalidity  or
unenforceability  of  any  Lien  securing  the  Guarantied  Obligations  or  the
liability of any Guarantor hereunder or of the Company or any other guarantor of
all or any part of the Guarantied  Obligations;  (viii) any amendment to, waiver
or  modification  of,  or  consent,  extension,  indulgence  or other  action or
inaction  under or in respect of the Note Purchase  Agreement,  the Notes or any
other  agreements,  documents,  certificates  and  instruments  now or hereafter
executed or delivered by the Company or any Guarantor or any other  guarantor in
connection with the Note Purchase Agreement (including,  without limitation, any
increase in the interest rate on the Notes); (ix) any change in any provision of
any applicable law or regulation; to the extent the same may be waived under any
such  applicable  law or regulation;  (x) any order,  judgment,  writ,  award or
decree of any court, arbitrator or governmental authority,  domestic or foreign,
binding on or affecting any Guarantor, the Company or any other guarantor or any
of  their  assets;   (xi)  the  certificate  of  incorporation  or  articles  of
organization (as the case may be), or the by-laws or limited  liability  company
agreement  (as the case may be) of any  Guarantor  or the  Company  or any other
guarantor;  (xii) any mortgage,  indenture,  lease, contract, or other agreement
(including  without limitation any agreement with  stockholders),  instrument or
undertaking  to which any Guarantor or the Company is a party or which  purports
to be  binding  on or affect any such  Person or any of its  assets;  (xiii) any
bankruptcy,  insolvency,  readjustment,   composition,  liquidation  or  similar
proceeding with respect to the Company,  any Guarantor or any other guarantor of
all or any portion of any Guarantied  Obligations or any such Person's  property
and any  failure  by any  Noteholder  to file or  enforce  a claim  against  the
Company,  any Guarantor or any such other Person in any such  proceeding;  (xiv)
any  failure on the part of the Company for any reason to comply with or perform
any of the terms of any other  agreement with any  Guarantor;  or (xv) any other
circumstance which might otherwise  constitute a legal or equitable discharge or
defense of a guarantor  (other than a defense of payment,  unless the payment on
which such defense is based was or is subsequently  invalidated,  declared to be
fraudulent or  preferential,  otherwise  avoided and/or required to be repaid to
the Company or a Guarantor, as the case may be, or the estate of any such party,
a trustee,  receiver or any other  Person  under any  bankruptcy  law,  state or
federal  law,  common law or  equitable  cause,  in which case there shall be no
defense of payment with respect to such payment).

     2C. Obligations  Unimpaired.  Each Guarantor agrees that each Noteholder is
authorized, without demand or notice, which demand and notice are hereby waived,
and without  discharging or otherwise affecting the obligations of any Guarantor
hereunder  (which shall remain absolute and  unconditional  notwithstanding  any
such  action  or  omission  to act),  from  time to time to (i)  renew,  extend,
accelerate or otherwise  change the time for payment of, or other terms relating
to, the Guarantied  Obligations  or any portion  thereof,  or otherwise  modify,

agreements, documents, certificates and instruments now or hereafter executed or
delivered by the Company or any Guarantor in  connection  with the Note Purchase
Agreement;  (ii) accept partial  payments on the Guarantied  Obligations;  (iii)
take and hold security for the Guarantied  Obligations or any portion thereof or
any other  liabilities of the Company,  the  obligations of any Guarantor  under

or any of the Guarantied  Obligations,  and exchange,  enforce,  waive, release,
sell, transfer, assign, abandon, fail to perfect,  subordinate or otherwise deal
with any such security;  (iv) apply such security and direct the order or manner
of sale thereof as any  Noteholder  may  determine in its sole  discretion;  (v)
settle,  release,  compromise,  collect or otherwise  liquidate  the  Guarantied
Obligations or any



portion  thereof and any  security  therefor or guaranty  thereof in any manner;

and  otherwise  create  additional  Guarantied  Obligations;  (vii) waive strict
compliance with the terms of the Note Purchase Agreement, the Notes or any other

delivered by the Company or any Guarantor in  connection  with the Note Purchase
Agreement  and otherwise  forbear from  asserting  any  Noteholder's  rights and

guaranty  therefor,  (h) of renewal,  extension  or  modification  of any of the
Guarantied Obligations, (i) of assignment, sale or other transfer of any Note to
a permitted  transferee  thereof,  or (j) of any of the  matters  referred to in
paragraph 2B and any right to consent to any thereof;

     (vi) presentment,  demand for payment or performance and protest and notice
of protest  with respect to the  Guarantied  Obligations  or any  guaranty  with
respect thereto; and

     (vii) any defenses or benefits  that may be derived from or afforded by law
which limit the liability of or exonerate  guarantors or sureties,  or which may
conflict with the terms of this Guaranty.

     Each Guarantor  agrees that no Noteholder  shall be under any obligation to
marshall  any assets in favor of such  Guarantor or against or in payment of any
or all of the Guarantied Obligations.

     No Guarantor  will exercise any rights which it may have acquired by way of
subrogation under this Guaranty, by any payment made hereunder or otherwise,  or
accept  any  payment on account  of such  subrogation  rights,  or any rights of
reimbursement  or  indemnity  or  contribution  or any rights or recourse to any
security for the Guarantied  Obligations or this Guaranty  unless at the time of
such Guarantor's  exercise of any such right there shall have been performed and
indefeasibly paid in full in cash all of the Guarantied Obligations.

     2E. Revival. Each Guarantor agrees that, if any payment made by the Company
or any other Person is applied to the Guarantied  Obligations and is at any time
annulled,  set aside,  rescinded,  invalidated,  declared  to be  fraudulent  or
preferential or otherwise  required to be refunded or repaid, or the proceeds of
any security are required to be returned by any  Noteholder to the Company,  its
estate, trustee,  receiver or any other Person,  including,  without limitation,
any  Guarantor,  under any bankruptcy  law, state or federal law,  common law or
equitable  cause,  then,  to the  extent  of such  payment  or  repayment,  such
Guarantor's  liability  hereunder  (and any  lien,  security  interest  or other
collateral  securing  such  liability)  shall be and  remain  in full  force and
effect,  as fully as if such payment had never been made,  or, if prior  thereto
this Guaranty shall have been canceled or surrendered (and if any lien, security
interest or other collateral securing such Guarantor's liability hereunder shall
have been released or terminated by virtue of such  cancellation  or surrender),
this Guaranty (and such lien,  security



interest or other collateral) shall be reinstated and returned in full force and
effect,  and such prior  cancellation or surrender shall not diminish,  release,
discharge,  impair or  otherwise  affect the  obligations  of such  Guarantor in
respect of the amount of such payment (or any lien,  security  interest or other
collateral securing such obligation).

     2F.  Obligation to Keep Informed.  Each Guarantor  shall be responsible for
keeping itself informed of the financial  condition of the Company and any other
Persons  primarily or secondarily  liable on the  Guarantied  Obligations or any
portion  thereof,  and of all  other  circumstances  bearing  upon  the  risk of
nonpayment  of the  Guarantied  Obligations  or any  portion  thereof,  and each
Guarantor agrees that no Noteholder shall have any duty to advise such Guarantor
of  information  known to such  Noteholder  regarding such condition or any such
circumstance.  If any Noteholder,  in its discretion,  undertakes at any time or
from  time to time to  provide  any  such  information  to any  Guarantor,  such
Noteholder shall not be under any obligation (i) to undertake any investigation,
whether or not a part of its regular  business  routine,  (ii) to  disclose  any
information which such Noteholder wishes to maintain  confidential,  or (iii) to
make  any  other  or  future  disclosures  of  such  information  or  any  other
information to any Guarantor.

     2G.  Bankruptcy.  If any Event of Default specified in clauses (ii) or (iv)
of Section 11(g) or Section 11(h) of the Note Purchase Agreement shall occur and
be continuing,  then each Guarantor agrees to immediately pay to the Noteholders
the full outstanding amount of the Guarantied Obligations without notice.

No waiver by any Guarantor in this Guaranty shall, in and of itself, be deemed a
waiver by the Company of any right of, or benefit afforded to, the Company under
the Note Purchase Agreement.

     3. REPRESENTATIONS AND WARRANTIES.

     Each Guarantor represents, covenants and warrants as follows:

     3A.  Organization.  Such  Guarantor is a corporation  or limited  liability
company (as the case may be) duly  organized and existing in good standing under
the laws of the state of its organization and is qualified to do business and in
good standing in every  jurisdiction  where the ownership of its property or the
nature of the business conducted by it makes such qualification necessary and in
which the failure to be so qualified or licensed  could be reasonably  likely to
have a Material Adverse Effect.

     3B. Power and Authority.  Such Guarantor has all requisite power to conduct
its business as currently  conducted and as currently  proposed to be conducted.
Such  Guarantor  has all  requisite  power to  execute,  deliver and perform its

Guaranty have been duly authorized by all requisite action and this Guaranty has
been duly executed and delivered by authorized officers of such Guarantor and is
the valid  obligation of such  Guarantor,  legally  binding upon and enforceable
against  such   Guarantor  in  accordance   with  its  terms,   except  as  such
enforceability may be limited by (i) bankruptcy,  insolvency,  reorganization or
other similar laws affecting the enforcement of creditors'  rights generally and
(ii) general principles of equity (regardless of whether such  enforceability is
considered in a proceeding in equity or at law).



     3C. Conflicting Agreements and Other Matters. The execution and delivery of
this  Guaranty  and the  fulfillment  of or the  compliance  with the  terms and
provisions  hereof will not conflict  with,  or result in a breach of the terms,
conditions or provisions  of, or  constitute a default  under,  or result in any
violation  of, or result in the creation of any Lien upon any of the  properties
or  assets  of  such  Guarantor  or any of its  Subsidiaries  pursuant  to,  the
certificate of  incorporation  or articles of organization (as the case may be),
the by-laws or limited  liability company agreement (as the case may be) of such
Guarantor  or  any of its  Subsidiaries,  any  award  of any  arbitrator  or any
agreement  (including any agreement with  stockholders  or holders of membership
interests  (as the case may be) of such  Guarantor  or  Persons  with  direct or
indirect ownership interests in stockholders or holders of membership  interests
(as the case may be) of such Guarantor),  instrument,  order, judgment,  decree,
statute,  law,  rule  or  regulation  to  which  such  Guarantor  or  any of its
Subsidiaries is subject. Neither such Guarantor nor any of its Subsidiaries is a
party to, or otherwise  subject to any provision  contained  in, any  instrument
evidencing any  Indebtedness  of such Guarantor or such Subsidiary any agreement
relating  thereto or any other  contract or  agreement  (including  its charter)
which limits the amount of, or otherwise  imposes  restrictions on the incurring
of, obligations of such Guarantor of the type to be evidenced by this Guaranty.

     3D. ERISA. The execution and delivery of this Guaranty will be exempt from,
or will not involve any  transaction  which is subject to, the  prohibitions  of
section 406 of ERISA and will not involve any  transaction  in  connection  with
which a penalty could be imposed under section 502(i) of ERISA or a tax could be
imposed pursuant to section 4975 of the Code.

     3E.  Governmental  Consent.  Neither the nature of such Guarantor or of any
Subsidiary  of  such  Guarantor  nor  any  of  their  respective  businesses  or
properties,  nor any  relationship  between such  Guarantor or any Subsidiary of
such Guarantor and any other Person, nor any circumstance in connection with the
execution,  delivery and performance of this Guaranty, is such as to require any
authorization,  consent, approval,  exemption or other action by or notice to or
filing with any court or administrative or governmental body (including, without
limitation,   notifications   required   by  the   Hart-Scott-Rodino   Antitrust
Improvements  Act of 1976, but excluding  routine filings after the date of this
Guaranty  with the  Securities  and  Exchange  Commission  and/or state Blue Sky
authorities).

     3F.  Regulatory  Status.  Neither such  Guarantor nor any Subsidiary of the
Guarantor  is  (i) an  "investment  company"  or a  company  "controlled"  by an
"investment  company" within the meaning of the Investment  Company Act of 1940,
as amended, (ii) a "holding company" or a "subsidiary company" or an "affiliate"
of a "holding company" or a "subsidiary company" of a "holding company",  within

     4. MISCELLANEOUS.

     4A.  Successors,  Assigns and Participants.  This Guaranty shall be binding
upon each  Guarantor  and its  successors  and  assigns  and shall  inure to the
benefit of each  Noteholder and its  successors,  transferees  and assigns;  all
references  herein to a Guarantor  shall be deemed to include its successors and
assigns,  and all references herein to any Noteholder shall



be  deemed to  include  its  successors  and  assigns.  This  Guaranty  shall be
enforceable by each Noteholder and any of such Noteholder's successors,  assigns
and participants, and any such successors and assigns shall have the same rights
and  benefits  with  respect  to each  Guarantor  under  this  Guaranty  as such
Noteholder hereunder.

     4B.  Consent to Amendments.  This Guaranty may be amended,  and a Guarantor
may take  any  action  herein  prohibited,  or omit to  perform  any act  herein
required  to be  performed  by it, if such  Guarantor  shall  obtain the written
consent to such amendment,  action or omission to act, of the Required Holder(s)
of the Notes,  except that, without the written consent of all of the holders of
the Notes,  (i) no amendment  to or waiver of the  provisions  of this  Guaranty
shall  change or affect  the  provisions  of this  paragraph  4B insofar as such
provisions  relate to proportions of the principal  amount of the Notes,  or the
rights of any  individual  holder of the  Notes,  required  with  respect to any
consent,  (ii) no Guarantor  shall be released from this Guaranty,  and (iii) no
amendment,  consent or waiver with respect to paragraph 2A or the  definition of
"Guarantied  Obligations" (except to add additional  obligations of the Company)
shall be effective.  Each Noteholder at the time or thereafter outstanding shall
be bound by any consent authorized by this paragraph 4B, whether or not the Note
held by such Noteholder shall have been marked to indicate such consent, but any
Notes issued  thereafter may bear a notation  referring to any such consent.  No
course of dealing  between any  Guarantor  and any  Noteholder  nor any delay in
exercising  any rights  hereunder or under any Note shall operate as a waiver of
any rights of any  Noteholder.  As used  herein,  the term "this  Guaranty"  and
references  thereto  shall  mean  this  Guaranty  as it may from time to time be
amended or  supplemented.  Notwithstanding  the foregoing,  this Guaranty may be
amended by the addition of additional  Guarantors,  as required  pursuant to the
Note Purchase Agreement.

     4C. Survival of  Representations  and  Warranties;  Entire  Agreement.  All
representations  and  warranties  contained  herein or made in  writing by or on
behalf of each Guarantor in connection  herewith shall survive the execution and
delivery of this Guaranty, the transfer by any Noteholder of any Note or portion
thereof or interest  therein and the payment of any Note, and may be relied upon
by any permitted transferee thereof, regardless of any investigation made at any
time by or on behalf of any  Noteholder  or any  permitted  transferee  thereof.
Subject to the preceding  sentence,  this Guaranty embodies the entire agreement
and understanding  between the parties hereto with respect to the subject matter
hereof and supersedes all prior  agreements and  understandings  relating to the
subject matter hereof.

     4D.  Notices.  All written  communications  provided for hereunder shall be

constitute a part of this Guaranty.

     4F.  Satisfaction  Requirement.  If any  agreement,  certificate  or  other
writing,  or any action taken or to be taken,  is by the terms of this  Guaranty
required to be satisfactory  to any Noteholder or the Required  Holder(s) of the
Notes, the determination of such  satisfaction  shall be made by such Noteholder
or such  Required  Holder(s),  as the  case may be,  in the  sole and  exclusive
judgment  (exercised  in good  faith)  of the  Person  or  Persons  making  such
determination.

     4G.  Governing  Law.  THIS  GUARANTY  SHALL BE  CONSTRUED  AND  ENFORCED IN
ACCORDANCE  WITH, AND THE RIGHTS OF THE PARTIES SHALL BE GOVERNED BY, THE LAW OF
THE  STATE OF  ILLINOIS  (EXCLUDING  ANY  CONFLICTS  OF LAW  RULES  WHICH  WOULD
OTHERWISE CAUSE THIS GUARANTY TO BE CONSTRUED OR ENFORCED IN ACCORDANCE WITH, OR
THE  RIGHTS  OF  THE  PARTIES  TO  BE  GOVERNED   BY,  THE  LAWS  OF  ANY  OTHER
JURISDICTION).

     4H.  Counterparts.  This Guaranty may be executed  simultaneously in two or
more counterparts, each of which shall be an original and constitute one and the
same  agreement.  It shall not be necessary in making proof of this  Guaranty to
produce or account for more than one such  counterpart.  Delivery of an executed
counterpart  of a  signature  page hereto by  facsimile  shall be  effective  as
delivery of a manually executed counterpart of this Guaranty.

     4I. SUBMISSION TO JURISDICTION. ANY LEGAL ACTION OR PROCEEDING WITH RESPECT
TO THIS GUARANTY OR THE OTHER TRANSACTION DOCUMENTS MAY BE BROUGHT IN THE COURTS
OF THE STATE OF ILLINOIS IN COOK COUNTY,  ILLINOIS,  OR OF THE UNITED STATES FOR
THE  NORTHERN  DISTRICT  OF  ILLINOIS  AND, BY  EXECUTION  AND  DELIVERY OF THIS
GUARANTY,  EACH  GUARANTOR  HEREBY  IRREVOCABLY  ACCEPTS,  UNCONDITIONALLY,  THE
JURISDICTION  OF THE  AFORESAID  COURTS  WITH  RESPECT  TO ANY  SUCH  ACTION  OR
PROCEEDING.  EACH  GUARANTOR  FURTHER  IRREVOCABLY  CONSENTS  TO THE  SERVICE OF
PROCESS OUT OF ANY OF THE AFOREMENTIONED COURTS IN ANY SUCH ACTION OR PROCEEDING
BY THE  MAILING OF COPIES  THEREOF BY  REGISTERED  OR  CERTIFIED  MAIL,  POSTAGE
PREPAID,  TO IT AT ITS ADDRESS  PROVIDED IN  PARAGRAPH  4D(i),  SUCH  SERVICE TO
BECOME  EFFECTIVE  UPON  RECEIPT.   EACH  GUARANTOR  AGREES  THAT  A  FINAL  AND
NON-APPEALABLE JUDGMENT IN ANY SUCH ACTION OR PROCEEDING SHALL BE CONCLUSIVE AND
MAY BE ENFORCED  IN ANY OTHER  JURISDICTION  BY SUIT ON SUCH  JUDGMENT OR IN ANY
OTHER  MANNER  PROVIDED BY LAW.  NOTHING  HEREIN  SHALL  AFFECT THE RIGHT OF ANY
HOLDER TO SERVE  PROCESS IN ANY OTHER  MANNER



PERMITTED BY LAW OR TO COMMENCE LEGAL  PROCEEDINGS OR OTHERWISE  PROCEED AGAINST
ANY  GUARANTOR IN ANY OTHER  JURISDICTION.  EACH  GUARANTOR  HEREBY  IRREVOCABLY
WAIVES ANY OBJECTION  WHICH IT MAY NOW OR HEREAFTER  HAVE TO THE LAYING OF VENUE
OF ANY OF THE AFORESAID  ACTIONS OR PROCEEDINGS  ARISING OUT OF OR IN CONNECTION
WITH THIS  GUARANTY  BROUGHT IN ANY OF THE AFORESAID  COURTS AND HEREBY  FURTHER
IRREVOCABLY  WAIVES  AND AGREES NOT TO PLEAD OR CLAIM IN ANY SUCH COURT THAT ANY
SUCH  ACTION OR  PROCEEDING  BROUGHT  IN ANY SUCH  COURT HAS BEEN  BROUGHT IN AN
INCONVENIENT FORUM.

     4J.  Independence  of  Covenants.  All covenants  hereunder  shall be given
independent  effect so that if a particular action or condition is prohibited by
any one of such  covenants,  the fact that it would be permitted by an exception
to, or otherwise be in compliance  within the limitations  of, another  covenant
shall not avoid the  occurrence  of a  Default  or an Event of  Default  if such
action is taken or such condition exists.

     4K.  Severability.  Any provision of this  Guaranty  which is prohibited or
unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective
to the extent of such prohibition or unenforceability  without  invalidating the
remaining provisions hereof, and any such prohibition or unenforceability in any
jurisdiction shall not invalidate or render  unenforceable such provision in any
other jurisdiction.
