OBLIGATIONS: Obligations means all amounts due to you of any nature, whether
they already exist, are incurred at this time, or are incurred in the future,
whether they are direct or indirect, whether they are absolute or contingent,
whether they are secured or unsecured, whether they are matured or unmatured,
whether they were incurred by the Borrower alone or jointly and/or severally
with others, whether they were originally contracted with you and /or other(s)
and now or later owing to you, whether or not they are represented by purchase
or repurchase agreements. Obligations include, but are not limited to, all sums
just described, late charges, disbursements, legal fees, and any amount still
due after you take any existing collateral.

CONSIDERATION: I give this Guaranty to you in return for your doing and having
done the following for Borrower: making loans, advances, extensions, renewal,
acquiring notes and security documents and extending and other financial
accommodation.

LIEN FOR LIABILITY OF GUARANTOR: I give to you a continuing lien for the amount
of all of my obligations and liabilities to you upon any and all of my property
including deposits and credits now or later held by you. My obligations and
liabilities to you, which will be called "Liabilities", mean all amount due to
you from me of any nature, including but not limited to amounts due under this
Guaranty whether they already exist, are incurred at this time, or are incurred

now or later owing to you. Property held by you means all property which is in
your possession, whether held now or coming into your possession latter, or
whether received by you for safekeeping, custody, pledge, transmission,
collection or otherwise. I authorize you to apply any such property, deposits or
credits at any time without notice to my Liabilities to you, regardless of
whether security is held for such Liabilities. All property held by you is
called "Collateral Security".

following without notice to me and I will continue to be fully liable under this
Guaranty which will remain in full force and effect:

limited to demands for additional Collateral Security or payment on account and

Liabilities.

WAIVER OF NOTICE: I waive notice of the following:

conclusively be presumed to have occurred in reliance on this Guaranty;

(b) Protest, demand for payment, notice of default and non-payment to any
Guarantor or Borrower or any other party responsible for the Obligations or

NATURE OF GUARANTY: This Guaranty is an absolute, continuing and unconditioned
guaranty of payment. It is not dependent on any other writing or fact, including
but not limited to the validity, regularity or enforceability of any of the
Obligations or purported Obligations, the taking or failure to take a security
interest in any property, the bankruptcy of Borrower or any other Guarantor, or
the termination of any other guaranty. You do not have to take any action
against Borrower or any other guarantor or any security for the Obligations
before seeking payment from me. I will remain liable hereunder despite the
occurrence or non-occurrence of any event which would in the absence of this
provision be deemed an equitable or legal discharge of a guarantor. This
Guaranty may be terminated by written notice actually delivered to and received
by you at your office at 275 Broad Hollow Rd., Melville, New York 11747, but
only as to new Obligations of Borrower subsequently incurred. Termination shall
be effective upon execution and delivery to me of written receipt for the
notice. In the event of termination, I will remain liable for Obligations of
Borrower created or arising before termination and all renewals, extensions,
refinancings and other Liabilities arising out of same and this Guaranty shall
continue in full force and effect with respect to same. All payments made on
account of or re-acknowledgment of the Obligations of Borrower, or any other
party liable therefore, including but not limited to me, shall be deemed made on
my behalf and shall start anew the running of the applicable statute of
limitations. The execution and delivery of this Guaranty shall not terminate any
other prior guaranties.

MISCELLANEOUS: All notices to or demands on me which you choose to make shall be
deemed effective when forwarded by mail, telegraph, telephone, cable radio or
otherwise to my last address or telephone number appearing on your books, if not
otherwise sooner given, and shall have the same effect as of notice was actually
delivered to and received by me in person. All of your rights and remedies under
this Guaranty are cumulative; you may exercise them singly or at the same time.
I waive the benefit of any homestead or other exemption to the extent permitted
by law. This Guaranty shall pass to and may be relied upon and enforced by any
of your successors or assignees and anyone who later holds any of the
Obligations. The term" Borrower" shall include (a) the Borrower listed above,
(b) all successors and entitles to which substantially all of the business and
assets of Borrower have been transferred, (c) in the case of a partnership, any
new partnerships created by admission of a new partner(s) or by dissolution by
death, resignation or withdrawal and (d) in the case of a corporation, any
corporation into or with which Borrower has merged, consolidated, reorganized or
absorbed. If you employ an attorney to enforce any of your rights under this
Guaranty or to obtain payment under this Guaranty, whether by lawsuit or
otherwise, I agree to pay a reasonable attorney fees. I waive trial by jury and
the right to interpose counterclaims of all types in any action by you against
me, although I may raise these claims in a separate lawsuit. You shall not be
deemed to have waived any right or remedy and delay, act, or omission. All
waivers by you must be in writing and signed by you and shall relate only to the
matters set forth therein. No waiver by you or any occasion shall act as a
waiver with respect to any future occasion. This Guaranty contains the
understanding between you and me. All changes must be in a signed writing. No
executory agreement shall be effective to change or modify or to discharge this
Guaranty. If more than one person signs this or any other Guaranty, each is
jointly and severally liable; if a partnership, each partner is bound jointly
and severally. I am jointly and severally liable with any other guarantor or
obligor of the obligation. If any portion of this Guaranty is unenforceable, the
remainder shall continue to be valid. This Guaranty shall be construed in
accordance with the laws of the State of New York (without regard to its
conflicts of laws rules) and I agree that service of process of certified mail,
return receipt requested, to my last address appearing on your books will be
sufficient to confer personal liability on me.

person amounts received by you on account of any Obligation, Liability or
Collateral Security, by reason of any judgment, settlement, or other
disposition, regardless of whether this Guaranty has been terminated or whether
any Obligation has been cancelled, I will be liable to you for all such amounts
as if they had never been paid to you. Notwithstanding anything to the contrary
in this guaranty, I hereby irrevocably waive all rights I may have at law or
equity (including without limit, any law subrogating me to your rights) to seek
contribution, indemnification, or any other form of reimbursement from the
