                                    GUARANTY



         GUARANTY  dated  as of  March  19,  2001  made  by  each  of the
undersigned (collectively, the "Guarantor") in favor of Voicenet, Inc., a
Delaware corporation (the "Payee").

         PRELIMINARY  STATEMENTS:  The Guarantor and ESS.Com,  L.L.C.,  a
Florida limited  liability  corporation (the "Borrower") are parties to a Letter
of  Intent  of even date  herewith  ("Letter  of  Intent")  with the Payee  that
contemplates,  among other  things,  Payee  making a loan to the Borrower in the
principal amount of $250,000 (the "Loan"), on the terms and conditions set forth
therein,  including the execution of this Guaranty. Payment of the Loan shall be
secured by this Guaranty and by a certain Pledge and Security  Agreement.  (This
Guaranty,  such Pledge and Security  Agreement  and the  promissory  note of the
Borrower  evidencing  the  Borrowers'  obligation  to repay the Loan are  herein
collectively  called the "Loan  Documents")  The  Guarantor  owns a  substantial
amount of the  stock or other  ownership  interests  of the  Borrower  and/or is
financially interested in its affairs.

         THEREFORE,  in order to induce the Payee to make the loan,  each
of the undersigned Guarantor, jointly and severally agrees) as follows:

         Section   1.   GUARANTY   OF   PAYMENT.   The   Guarantor
unconditionally and irrevocably  guarantees to the Payee the punctual payment of
all  sums now  owing or which  may in the  future  be owing by the  Borrower  on
account  of the  Loan,  when the same are due and  payable,  whether  at  stated
maturity,  by  acceleration or otherwise,  and whether for principal,  interest,
fees,  expenses,  indemnification  or otherwise (all of the foregoing sums being
the "Liabilities"). The Liabilities include, without limitation, interest
accruing after the commencement of a proceeding under bankruptcy,  insolvency or
similar  laws of any  jurisdiction  at the  rate or rates  provided  in the Loan
Documents.  This Guaranty is a guaranty of payment and not of  collection  only.
The  Payee  shall not be  required  to  exhaust  any right or remedy or take any
action against the Borrower or any other person or entity or any collateral. The
Guarantor  agrees that, as between the Guarantor and the Payee,  the Liabilities
may be  declared  to be due and  payable  for  the  purposes  of  this  Guaranty
notwithstanding  any stay,  injunction or other  prohibition  which may prevent,
delay or vitiate any  declaration  as regards the Borrower and that in the event
of a declaration or attempted  declaration,  the Liabilities  shall  immediately
become due and payable by the Guarantor for the purposes of this Guaranty.

         Section 2. GUARANTY  ABSOLUTE.  The Guarantor  guarantees
that the Liabilities  shall be paid strictly in accordance with the terms of the
Facilities.  The liability of the Guarantor  under this Guaranty is absolute and
unconditional  irrespective  of: (a) any change in the amount,  time,  manner or
place of payment  of, or in any other term of, all or any of the Loan  Documents
or Liabilities,  or any other amendment or waiver of or any consent to departure
from any of the terms of any Loan  Document  or  Liability;  (b) any  release or
amendment  or waiver of, or consent to  departure  from,  any other  guaranty or
support document, or any exchange,  release or non-perfection of any collateral,
for all or any of the Loan Documents or  Liabilities;  (c) any present or future
law, regulation or order of any jurisdiction (whether of right or in fact) or of
any agency thereof purporting to reduce, amend,  restructure or otherwise affect
any term of any Loan  Document or  Liability;  (d) without  being limited by the
foregoing,  any lack of  validity  or  enforceability  of any Loan  Document  or
Liability; and (e) any other









defense, setoff or counterclaim whatsoever with respect to the Loan Documents or
the transactions contemplated thereby which might constitute a defense available
to, or discharge of, the Borrower or a guarantor.

         Section  3.  GUARANTY  IRREVOCABLE.  This  Guaranty  is a
continuing  guaranty of the payment of all Liabilities now or hereafter existing
and  shall  remain  in  full  force  and  effect  until  payment  in full of all
Liabilities and other amounts  payable under this Guaranty or, if earlier,  upon
consummation  of the  merger of Finger  Lakes  Technology  Corp.  into the Payee
contemplated by the Letter of Intent.

         Section 4. REINSTATEMENT. This Guaranty shall continue to
be effective or be reinstated, as the case may be, if at any time any payment of
any of the  Liabilities  is rescinded or must otherwise be returned by the Payee
on the insolvency,  bankruptcy or  reorganization  of the Borrower or otherwise,
all as though the payment had not been made.

         Section 5. SUBROGATION.  The Guarantor shall not exercise
any rights against the Borrower which it may acquire by way of  subrogation,  by
any payment made under this  Guaranty or  otherwise,  until all the  Liabilities
have been paid in full and the Facilities are no longer in effect. If any amount
is paid to the Guarantor on account of subrogation rights under this Guaranty at
any time when all the  Liabilities  have not been paid in full, the amount shall
be held in trust for the benefit of the Payee and shall be promptly  paid to the
Payee  to be  credited  and  applied  to the  Liabilities,  whether  matured  or
unmatured  or  absolute  or  contingent,  in  accordance  with the  terms of the
Facilities.  If the  Guarantor  makes payment to the Payee of all or any part of
the  Liabilities and all the Liabilities are paid in full and the Facilities are
no longer in effect,  the Payee shall, at the Guarantor's  request,  execute and
deliver to the Guarantor  appropriate  documents,  without  recourse and without
representation or warranty, necessary to evidence the transfer by subrogation to
the Guarantor of an interest in the Liabilities resulting from the payment.

         Section 6.  SUBORDINATION.  Without  limiting the Payee's
rights under any other  agreement,  any liabilities  owed by the Borrower to the
Guarantor in connection with any extension of credit or financial  accommodation
by the  Guarantor  to or for the  account  of the  Borrower,  including  but not
limited to interest  accruing at the agreed contract rate after the commencement
of  a  bankruptcy  or  similar  proceeding,   are  hereby  subordinated  to  the
Liabilities, and such liabilities of the Borrower to the Guarantor, if the Payee
so requests,  shall be  collected,  enforced  and  received by the  Guarantor as
trustee  for the Payee and  shall be paid  over to the Payee on  account  of the
Liabilities but without reducing or affecting in any manner the liability of the
Guarantor under the other provisions of this Guaranty.

         Section 7.  CERTAIN  TAXES.  The Guarantor further agrees
that  all  payments  to be made  hereunder  shall  be  made  without  setoff  or
counterclaim  and free and clear of,  and  without  deduction  for,  any  taxes,
levies, imposts, duties, charges, fees, deductions, withholdings or restrictions
or  conditions  of any  nature  whatsoever  now or  hereafter  imposed,  levied,
collected,  withheld or assessed by any country or by any political  subdivision
or taxing authority thereof or therein ("Taxes").

represents  and warrants  that this  Guaranty:  (a) has been  authorized  by all
necessary  action;  (b)  does  not  violate  any  agreement,   instrument,  law,
regulation  or order  applicable  to the  Guarantor;  (c) does not  require  the

waiver of any  provision of this  Guaranty,  nor consent to any departure by the
Guarantor  therefrom,  shall be effective  unless it is in writing and signed by
the  Payee,  and then the  waiver  or  consent  shall be  effective  only in the
specific  instance and for the specific  purpose for which given.  No failure on
the part of the Payee to exercise,  and no delay in exercising,  any right under
this  Guaranty  shall  operate  as a waiver or  preclude  any  other or  further
exercise thereof or the exercise of any other right.

         Section 12.  EXPENSES.  The Guarantor shall reimburse the

limiting the generality of the foregoing:  (a) the  obligations of the Guarantor
under this Guaranty shall continue in full force and effect and shall be binding
on any  successor  partnership  and on previous  partners  and their  respective
estates  if the  Guarantor  is a  partnership,  regardless  of any change in the
partnership as a result of death retirement or otherwise;  and (b) the Payee may
assign,  sell  participations  in or  otherwise  transfer  its rights  under the
Facilities  to any other person or entity,  and the other person or entity shall
