2.          Guaranty

2.1       Continuing Guaranty of Payment.  In consideration of RZB agreeing to
the  Loan  Documents  and/or extending or continuing credit to the Borrower in
connection  therewith,  the  Guarantor  irrevocably,  absolutely  and
unconditionally  guarantees  to  RZB  the  payment  when due of all Guaranteed
Obligations, together with interest thereon and other charges related thereto.
For  purposes of this Guaranty, the Guaranteed Obligations shall be due on the
earliest  of:

     2.a.          the  due  date  thereof  (by  acceleration  or  otherwise),

     2.b.          with  respect  to any obligation due on demand, upon demand
therefor  made  by  RZB  upon  the  Borrower  or  the  Guarantor,

     2.c.      the giving of notice by RZB to the Borrower or Guarantor of the
occurrence  of  any default by the Guarantor hereunder (including any material
misrepresentation  by  the  Guarantor  herein  or  in  connection  herewith),

     2.d.       the occurrence of a material adverse change in the Borrower or
the  Guarantor,

     2.e.       the Borrower shall disaffirm or disavow any of its obligations
under  the  Loan  Documents  or  the  Guarantor  shall  disaffirm  any  of its
obligations  hereunder,

     2.f.          the  Borrower  or  the Guarantor shall admit in writing its
inability  to  pay  its  debts  as  they  become  due,

     2.g.        any indebtedness (direct or contingent) for borrowed money of
the  Borrower  or the Guarantor shall not be paid as and when the same becomes
due  and  payable,  including  any  applicable  grace  period,  or

     2.h.          the  commencement  of any bankruptcy, insolvency or similar
proceeding  by  or  against  the  Borrower  or  the  Guarantor.

     This  is  a guaranty of payment rather than of collection; this is also a
continuing guaranty and all liabilities to which this Guaranty applies, or may
apply,  under  the  terms  hereof  shall  be  presumed to have been created in
reliance  hereon.

     2.2      Nature of Obligations.  The obligations of the Guarantor to make
payments  to  RZB hereunder are direct and primary obligations which shall not
be  discharged  for  any  reason until RZB has been indefeasibly paid in full.
Without  limiting  the  generality  of  the  foregoing, the obligations of the
Guarantor  hereunder  shall  remain  in  force  irrespective  of:

     2.  a.          any invalidity, illegality or unenforceability of, or any
defect  in, any of the Loan Documents or Guaranteed Obligations or any defense
which  the  Borrower  may  have  with  respect  thereto,

     2.  b.        the existence or absence of any legal action to enforce the
Guaranteed  Obligations  or  the  Loan Documents or any security therefor, the
issuance  of  any  judgment therefor or the execution of any such judgment, or

     2.  c.          any other circumstance which might otherwise constitute a
defense  available  to  or  discharge  of,  a guarantor or surety of any type.

     This  guaranty  is  several  and  independent  of,  and  may  be enforced
regardless of, any other obligation (direct or contingent) of the Guarantor or
any  other  "Person" (such term to include any person or legal or governmental
entity, association, agency or instrumentality) with respect to the Guaranteed
Obligations.

     2.3  Payments.   All payments by the Guarantor hereunder shall be made to
RZB  without  set-off, recoupment, deduction or counterclaim at its office set
forth  below (or as RZB may otherwise direct) in lawful currency of the United
States  of  America  and in immediately available funds.  Without limiting the
foregoing, all payments hereunder shall be made free and clear of, and without
deduction  for,  any  present  or future withholding or other taxes or duties,
including  stamp  duties,  or  other  charges  of  any  nature imposed on such
payments  by  or  on  behalf of any government or any political subdivision or
agency thereof or therein.  If any such taxes, duties or charges are so levied
or imposed on any such payment, the Guarantor will make additional payments in
such amounts as may be necessary so that the net amount received by RZB, after
deduction  for  or  on  account  of all such taxes, duties or charges, will be
equal to the amount provided for herein.  The Guarantor shall furnish promptly
to  RZB  official receipts evidencing the payment of any such taxes, duties or
charges  paid  by  the  Guarantor.

3.    Special  Agreements  of  Guarantor

3.1     Subordination.  Subject to the next following sentence of this Section
3.1:

     3.a.          all  claims  of the Guarantor against the Borrower shall be
subject  and  subordinate  to  the  prior  payment  to  RZB  of all Guaranteed
Obligations  and  all  obligations  of  the  Guarantor  hereunder,  and

     3.b.        the Guarantor shall not be entitled to receive any payment or
exercise  any set-off in respect of any such claim and, to the extent any such
payment  is  received  (whether  directly,  by  way of dividend in bankruptcy,
set-off  or  otherwise), the Guarantor will forthwith deliver the same (or the
value  thereof)  to RZB in precisely the form received (except for endorsement
or  assignment where necessary), for application to the Guaranteed Obligations
and,  until  so  delivered, the same shall be held in trust as the property of
RZB.

     Notwithstanding  the  foregoing, except as provided in Section 3.2, until
the  occurrence of any default or event of default under the Loan Documents or
this Guaranty, or any demand for payment of any of the Guaranteed Obligations,
the Guarantor may receive and retain payment in respect of any obligation owed
to  it  by  the  Borrower.    If  the  Guarantor  fails  to make any necessary
endorsement  or  assignment  of  any  instrument  of  payment  to which RZB is
entitled,  RZB  and  any  of  its officers or employees are hereby irrevocably
authorized  to  make  the  same  on  behalf  of  the  Guarantor.

     3.2    No  Subrogation.    The  Guarantor  hereby  waives  any  right  of
subrogation that it may have with respect to any payment that it may have made
to  RZB  hereunder.

     3.3    No Contribution.  The Guarantor agrees that it shall have no legal
or  equitable  right  or  claim  (by  way  of indemnification, contribution or
otherwise)  against  any  subsidiary  or  affiliate  of RZB which has issued a
guaranty  to  RZB  in  respect  of  the  Guaranteed  Obligations.

     3.4    Waivers.    Except  to  the extent required by law which cannot be
waived,  the Guarantor waives notice of acceptance of this Guaranty and notice
of  any  liability  to  which it may apply, and waives diligence, presentment,
demand  for  payment,  protest,  notice  of dishonor or nonpayment of any such
liabilities,  suit or taking other action or making any demand by RZB against,
and  any  other notice to, any party liable thereon (including the Guarantor).
The  Guarantor  agrees that RZB may at any time and from time to time, upon or
without  any  terms  or  conditions  and  in  whole  or  in  part:

     3.   a.     change the manner, place or terms of, and/or change or extend
the  time  of  payments of, renew or alter, any of the Guaranteed Obligations,
any  security  therefor,  or  any liability incurred directly or indirectly in
respect  thereof,  and this Guaranty shall apply to the Guaranteed Obligations
so  changed,  extended,  renewed  or  altered,

     3.b.      fail to record, perfect or protect, or sell, exchange, release,
surrender, realize upon or otherwise deal with in any manner and in any order,
any  property  or  Person  whatsoever at any time securing or guaranteeing the
Guaranteed  Obligations  or any liabilities (including any of those hereunder)
incurred  directly  or  indirectly  in  respect  thereof or hereof, and/or any
offset  thereagainst,

     3.c.          exercise  or refrain from exercising any rights against the
Borrower  or  any  other  Person (including any guarantor) or otherwise act or
refrain  from  acting,

     3.d.     settle, release or compromise any of the Guaranteed Obligations,
any  security  therefor  or  any  liability (including any of those hereunder)
incurred  directly  or  indirectly  in  respect  thereof  or  hereof,  and may
subordinate  the  payment  of all or any part of the Guaranteed Obligations to
the payment of any other liability (whether due or not) of the Borrower to the
creditors  of  the  Borrower  (including  RZB),

     3.e.       apply any sums by whomsoever paid or howsoever realized to any
liability  or  liabilities of the Borrower to RZB regardless of what liability
or  liabilities  of  the Borrower remain unpaid, provided that payments by the
Guarantor  pursuant  to  this  Guaranty  shall  be  applied to its obligations
hereunder,  but  in  such  order  as  RZB  may  determine,

     3.f.        consent to or waive any breach of or act, omission or default
under,  or  modify  or  amend  any  provision  of,  the Loan Documents, and/or

     3.g.  increase the amount of indebtedness of the Borrower to RZB, whether
under  the  Loan  Documents  or  otherwise.

     It is understood and agreed that RZB may take any such action without the
consent  of,  or notice to, the Guarantor, without incurring responsibility to
the  Guarantor,  and  without  impairing  or  releasing the obligations of the
Guarantor  hereunder.

     3.5        Amounts Reclaimed.  If claim is made upon RZB for repayment or
recovery  of  any  amount  received  on  account  of  any  of  the  Guaranteed
Obligations  and  RZB  repays  all  or  part  of  said  amount  by  reason of:

     3.a       any judgment, decree or order of any court, administrative body
or  trustee in bankruptcy (or other Person acting on behalf of the Borrower or
its  estate)  or,

     3.b        any settlement or compromise of any such claim effected by RZB
with  any  such  claimant  (including  the  Borrower),  or

     3.c.          any  other  reason,

     then, and in any such event, the Guarantor agrees that any such repayment
(by  reason  of  any such judgment, decree, order, settlement or compromise or
otherwise)  shall  be  binding  upon  the  Guarantor,  notwithstanding  any
cancellation  of  the Loan Documents or this Guaranty, and the Guarantor shall
be and remain liable to RZB hereunder for the amount so repaid or recovered to
the  same  extent  as  if  such  amount  had  never  been  received  by  RZB.

     3.6    Interest.    If the Guarantor fails to pay when due any obligation
hereunder,  then,  to  the extent permitted by law, such obligation shall bear
interest,  payable  on  demand,  from  the  due  date  thereof until paid at a
fluctuating  rate per annum equal to 2% in excess of the Base Lending Rate (as
hereinafter  defined);  provided  that  no  such  additional interest shall be
payable  in respect of any such obligation on which interest is simultaneously
accruing  pursuant to the Loan Documents.  The term "Base Lending Rate" means,
for  any day, the higher of (i) the rate announced by The Chase Manhattan Bank
(the  "Bank")  from time to time at its principal office in New York, New York
as  its  prime rate for domestic (United States) commercial loans in effect on
such day and (ii) the Federal Funds Rate (as hereinafter defined) in effect on
such day plus 1/2%.  (Such Base Lending Rate is not necessarily intended to be
the  lowest rate of interest charged by the Bank in connection with extensions
of  credit.)  Each  change  in  the  Base  Lending  Rate  shall  result  in  a
corresponding  change  in the interest rate and such change shall be effective
on  the  effective  date  of  such  change  in  the  Base  Lending  Rate.

     The  term  "Federal Funds Rate" means, for any day, the overnight federal
funds rate in New York City, as published for such day (or, if such day is not
a  New York Business Day, for the next preceding New York Business Day) in the
Federal  Reserve  Statistical Release H.15 (519) or any successor publication,
or  if  such rate is not so published for any day which is a New York Business
Day,  the  average  of  the quotations for such day on overnight federal funds
transactions  in  New York City received by RZB or the Bank from three federal
funds  brokers  of  recognized  standing  selected  by  RZB  or  the  Bank.

     3.7    The  Borrower.    The Guarantor will not cease to own (directly or
indirectly), free and clear of all liens and encumbrances, the interest in the
Borrower  which  it  presently  owns  (if  any)  and will not agree to sell or
subject to any lien, encumbrance or any other security device such interest at
any  future  time,  until the Loan Documents are terminated and all Guaranteed
Obligations  and  all obligations of the Guarantor hereunder are paid in full.

     3.8    Information.    The  Guarantor  will  promptly furnish to RZB such
information  regarding  its and the Borrower's business, affairs and financial
condition  as  RZB  may  from  time  to  time  reasonably  request.

     3.9  Secured Obligations.  The Guarantor shall not grant, create, assume,
incur  or  suffer  to exist a security interest in or lien or encumbrance upon
any  of  its  property  for  the  purpose  of  securing the obligations of the
Borrower  and/or  itself  to  any  other  Person unless such Person shall have
entered  into  an  intercreditor  agreement  with  RZB  in  form and substance
satisfactory  to  RZB.

     4.    Representations,  Warranties  and  Agreements

     In  order  to  induce  RZB  to  agree to the Loan Documents, to extend or
continue  the  credit  provided  thereby  and  to  accept  this  Guaranty, the
Guarantor makes the following representations, warranties and agreements which
shall  survive  the  execution  and  delivery  of  this  Guaranty:

     4.1    Organizational  Status  and  Power.    The  Guarantor:

     4.a    is,  and  will continue to be, duly organized and validly existing
under the law of the jurisdiction of its organization, as indicated in Section
1,  and

     4.b    has  the  power  to own its assets, to conduct its business as now
conducted  and  to  enter  into  and  perform the provisions of this Guaranty.

     4.2    Legality.    The entering into and performance by the Guarantor of
this  Guaranty  has  been  duly  authorized  by  all  necessary  corporate and
stockholder  action  or other action required by its organizational documents,
and  do  not  contravene any existing law or any legal order applicable to, or
license or permit granted to, the Guarantor, or any agreement or instrument to
which  the Guarantor is a party or to which it or any of its assets is subject
or  any  provision  of  the  Guarantor's  organizational  documents.

      This  Guaranty  is  the  legal,  valid  and  binding  obligation  of the
Guarantor,  enforceable  in  accordance  with  its  terms.

     4.3    Governmental  Approvals.    Neither  any  action  by  or  with any
governmental  or  public body or authority (including, without limitation, any
exchange  control  or monetary authority), or any subdivision thereof, nor any
other  legal  formality  is  required  in  connection  with the entering into,
performance  or  enforcement  of  this  Guaranty  (collectively, "Governmental
Approvals"),  except  such  as  has been obtained or taken and with respect to
which a copy or other satisfactory evidence thereof has been furnished to RZB.
The  Guarantor  will  maintain  all requisite Governmental Approvals until the
Loan  Documents  are  terminated and the Guaranteed Obligations and all of its
obligations  hereunder  are  paid  in  full.

     4.4   Financial Condition.  The most recent year-end financial statements
of  the Guarantor furnished to RZB prior to the date hereof have been prepared
in  accordance  with  generally  accepted  accounting  principles consistently
applied  and  fairly  present  the  financial  condition  and  the  results of
operations  of  the  Guarantor  as  at the end of and for the reporting period
covered thereby.  There are no material liabilities or any material unrealized
or  anticipated losses from unfavorable commitments which are not disclosed in
such  financial  statements.  There has been no material adverse change in the
operations,  business  or  financial  condition of the Guarantor from that set
forth in such financial statements; and there are no legal proceedings pending
or,  to  the  knowledge  of the Guarantor threatened, against or affecting the
Guarantor  which  might  (individually  or  in the aggregate) result in such a
material  adverse  change.

     4.5    Investment Company Act.  The Guarantor is not required to register
under  the  Investment  Company  Act  of 1940, as amended (the "Act"), and the
entering  into of this Guaranty and the performance thereof do not violate any
provision  of  the  Act.

     On  each  anniversary  of the date of this Agreement, the Guarantor shall
deliver to RZB a certificate of an authorized officer of the Guarantor wherein
the  Guarantor  shall reaffirm to RZB the continuing truth and validity of the
representations  and  warranties  set  forth  in the foregoing Section 4.  The
failure  of the Guarantor to deliver and/or RZB to demand such delivery of the
foregoing  certificate  shall  in  no  way affect or invalidate the continuing
nature  of  the  representations  and  warranties  set  forth in the foregoing
Section  4.

5.    Miscellaneous

     5.1   Payment of Expenses.  The Guarantor agrees to pay all out-of-pocket
costs  and  expenses  of RZB arising in connection with its administration and
enforcement of, or preservation of its rights under, this Guaranty (including,
without  limitation, the reasonable fees and expenses of counsel for RZB), and
all  stamp  taxes  (including  interest  and  penalties,  if any) which may be
payable  in  respect of this Guaranty or of any modification of this Guaranty.

     5.2    Modification.   This Guaranty may be modified or waived only by an
instrument  in  writing  signed  by  the party against whom enforcement of the
modification  or  waiver  is  sought.

     5.3    THIS  GUARANTY  AND  THE  RIGHTS  AND  OBLIGATIONS  OF THE PARTIES
HEREUNDER  SHALL  BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAW OF
THE  STATE  OF  NEW  YORK  (WITHOUT REGARD TO PRINCIPLES OF CONFLICTS OF LAW).

     5.4   Notices.  Communications given to any party in connection with this
Guaranty  shall  be  in  English  and  in  writing and shall be effective when
delivered  at  its  address  set  forth  herein, as the same may be changed by
written  notice to the other party.  Written communications may be in any form
of  writing  howsoever  transmitted.

     5.5    Waiver.   RZB's rights, powers, privileges and remedies under this
Guaranty  or  applicable law are cumulative and not exclusive and shall not be
waived,  precluded  or limited by any failure or delay in the exercise thereof
or  by RZB's exercise, or partial exercise, of any thereof or by any course of
dealing  between  the  Guarantor  and  RZB.    No  notice  to or demand on the
Guarantor  in  any  case  shall  entitle the Guarantor to any other or further
notice  or  demand in similar or other circumstances or constitute a waiver of
the  right  of  RZB to any other or further action in any circumstance without
notice  or  demand.

     5.6    Descriptive  Headings.    The  descriptive  headings  used in this
Guaranty  are  for  convenience  only  and  shall  not be deemed to affect the
meaning  or  construction  of  any  provision  hereof.

     5.7    Benefit  of  Guaranty.    This  Guaranty shall be binding upon the
Guarantor  and  its  successors and assigns and shall inure to the benefit of,
and  be enforceable by, RZB and its successors and assigns and, in particular,
any  holder or assignee from time to time of the Loan Documents; provided that
the  Guarantor  may  not  assign  any  of  its rights or obligations hereunder
without  the  prior  written  consent  of  RZB.

     5.8    Set-Off.    RZB  is  authorized at any time and from time to time,
without  notice to the Guarantor or to any other Person, any such notice being
hereby expressly waived, to set off and apply any and all deposits (general or
special) and any other indebtedness at any time held or owing by RZB to or for
the  credit  or  the  account  of  the Guarantor against and on account of the
obligations  of  the Guarantor under this Guaranty, irrespective of whether or
not  RZB shall have made any demand hereunder or any demand for payment of any
Guaranteed Obligation and although said obligations, liabilities or claims, or
any of them, shall be contingent or unmatured, and the Guarantor hereby grants
to  RZB  a  security  interest  in  all  such  deposits  and  indebtedness.

     5.9  Jurisdiction and Immunity.  The Guarantor represents and agrees that
it  is  not  entitled  to,  and to the extent it hereafter becomes so entitled
hereby  waives,  any  immunity, sovereign or otherwise, with respect to itself
and its property from jurisdiction, service, attachment (both before and after
judgment)  and execution in legal proceedings wherever commenced to enforce or
collect  upon  this  Guaranty.

     5.10    Survival.    The  provisions  of Sections 3.5, 5.1 and 5.11 shall
survive  the  termination  and  cancellation  of  this  Guaranty  and,  after
cancellation  and return to the Guarantor, a photocopy hereof may be submitted
as  evidence of such surviving obligations.  Nothing herein shall preclude RZB
from  establishing  such  obligations  by  other  means.

     5.11    WAIVER  OF  JURY  TRIAL.    EACH  OF THE GUARANTOR AND RZB HEREBY
KNOWINGLY,  VOLUNTARY  AND INTENTIONALLY WAIVES ANY AND ALL RIGHTS IT MAY HAVE
TO  A  TRIAL BY JURY IN RESPECT OF ANY LITIGATION BASED ON, OR ARISING OUT OF,
UNDER,  OR IN CONNECTION WITH THIS GUARANTY OR ANY OTHER DOCUMENT OR AGREEMENT
EXECUTED  IN CONNECTION HEREWITH, OR ANY COURSE OF CONDUCT, COURSE OF DEALING,
STATEMENTS  (WHETHER  VERBAL  OR  WRITTEN),  OR  ACTIONS OF THE GUARANTOR, THE
BORROWER  OR RZB.  THIS PROVISION IS A MATERIAL INDUCEMENT FOR RZB'S EXTENDING
TO  THE  BORROWER  THE  CREDIT  FACILITY  TO  WHICH  THIS  GUARANTY  RELATES.

     5.12    Consent  to  Jurisdiction.   The Guarantor hereby agrees that ANY
LEGAL ACTION OR PROCEEDING AGAINST THE GUARANTOR WITH RESPECT TO THIS GUARANTY
OR  ANY LOAN DOCUMENT MAY BE BROUGHT IN THE COURTS OF THE STATE OF NEW YORK IN
THE  CITY  OF  NEW  YORK  OR  OF THE UNITED STATES OF AMERICA FOR THE SOUTHERN
DISTRICT OF NEW YORK, as RZB may elect, and, by execution and delivery hereof,
the  Guarantor  accepts  and  consents  to,  for  itself and in respect of its
property,  generally  and  unconditionally,  the jurisdiction of the aforesaid
courts  and agrees that such jurisdiction shall be exclusive, unless waived by
RZB in writing, with respect to any action or proceeding brought by it against
RZB  and any question relating to usury.  Nothing herein shall limit the right
of  RZB  to bring proceedings against the Guarantor in the courts of any other
jurisdiction.    Service  of  process  out  of  any such courts may be made by
mailing  copies  thereof  by registered or certified mail, postage prepaid, to
the  Guarantor  at its address for notices as specified herein and will become
effective  30  days  after  such  mailing.  The Guarantor agrees that Sections
5-1401  and  5-1402  of  the  General Obligations Law of the State of New York
shall apply to this Guaranty and the Loan Documents and, to the maximum extent
permitted by law, waives any right to any defense of, or to dismiss any action
or proceeding brought before said court on the basis of, forum non conveniens.

IN  WITNESS WHEREOF, the Guarantor has caused this Guaranty to be executed and
delivered  by  its  duly  authorized  officer(s)  as  of  the date first above
written.
