the voice which is normally 64 KB (1DSO) could get up to 8 to 1 depending on the
quality that is acceptable to SELLER. Where they are used to getting 24 DSO's
per T1, with compression they will have left over bandwidth which will be used
for data.

                                                                               9

     6.   RIGHTS AND REMEDIES UPON DEFAULT.

          (a)  If any Event of Default shall occur and be continuing, Secured
Party may exercise in addition to all other rights and remedies granted to it
under this Security Agreement and under any other instrument or agreement
securing, evidencing or relating to the Secured Obligations, all rights and
remedies of a secured party under the UCC. Without limiting the generality of
the foregoing, Grantor expressly agrees that in any such event, and during the
existence and continuance of an Event of Default, Secured Party, without demand
of performance or other demand, advertisement or notice of any kind (except the
notice specified below of time and place of public or private sale) to or upon
Grantor or any other person (all and each of which demands, advertisements and
notices are hereby expressly waived to the maximum extent permitted by the UCC
and other applicable law), may forthwith collect, receive, appropriate and
realize upon the Collateral, or any part thereof, and may forthwith sell,.
lease, assign, give an option or options to purchase or sell or otherwise
dispose of and deliver said Collateral (or contract to do so), or any part
thereof, in one or more parcels at public or private sale or sales, at any
exchange or broker's board or at any of Secured Party's offices or elsewhere at
such prices as it may deem best, for cash or on credit or for future delivery
without assumption of any credit risk. Secured Party shall have the right upon
any such public sale or sales, and, to the extent permitted by law, upon any
such private sale or sales, to purchase the whole or any part of said Collateral
so sold, free of any right or equity of redemption, which equity of redemption
Grantor hereby releases. Grantor further agrees, at Secured Party's request and
during the existence and continuance of an Event of Default, to assemble the
Collateral and make it available to Secured Party at places which Secured Party
shall reasonably select, whether at Grantor's premises or elsewhere. Secured
Party shall apply the net proceeds of any such collection, recovery, receipt,
appropriation, realization or sale as provided in Section 6(d) hereof, Grantor
remaining liable for any deficiency remaining unpaid after such application, and
only after so paying over such net proceeds and after the payment by Secured
Party of any other amount required by any provision of law, need Secured Party
account for the surplus, if any, to Grantor. To the maximum extent permitted by
applicable law, Grantor waives all claims, damages, and demands against Secured
Party arising out of the repossession, retention or sale of the Collateral
except such as arise out of the gross negligence or willful misconduct of
Secured Party. Grantor agrees that Secured Party need not give more than ten
(10) days' notice (which notification shall be deemed given when mailed or
delivered on an overnight basis, postage prepaid, addressed to Grantor at its
address set forth on the signature page hereof, of the time and place of any
public sale or of the time after which a private sale may take place and that
such notice is reasonable notification of such matters. Grantor shall remain
liable for any deficiency if the proceeds of any sale or disposition of the
Collateral are insufficient to pay all amounts to which Secured Party is
entitled, Grantor also being liable for the reasonable fees of any attorneys
employed by Secured Party to collect such deficiency.

Secured Party, including, without limitation, reasonable attorneys' fees,
reasonably incurred in connection with the enforcement of any of its rights and

                                                                              10

          (c)  Grantor hereby waives presentment, demand, protest or any notice
(to the maximum extent permitted by applicable law) of any kind in connection
with this Security Agreement or any Collateral.

          (d)  The Proceeds of any sale, disposition or other realization upon
all or any part of the Collateral shall be distributed by Secured Party in the
following order of priorities:

               FIRST, to Secured Party in an amount sufficient to pay in full
the reasonable costs of Secured Party in connection with such sale, disposition
or other realization, including all fees, costs, expenses, liabilities and
advances reasonably incurred or made by Secured Party in connection therewith,
including, without limitation, reasonable attorneys' fees;

               SECOND, to Secured Party in an amount equal to the then unpaid
Secured Obligations; and

               FINALLY, upon payment in full of the Secured Obligations, to
Grantor or its representatives, in accordance with the UCC or as a court of
competent jurisdiction may direct.

     7.   INDEMNITY. Grantor agrees to defend, indemnify and hold harmless
Secured Party, Banks, and their officers, employees, and agents against (a) all
obligations, demands, claims and liabilities claimed or asserted by any other
party in connection with the transactions contemplated by this Security
Agreement and (b) all losses or expenses in any way suffered, incurred or paid
by Secured Party or Banks as a result of or in any way arising out of or
following transactions between Secured Party, Banks and Grantor, whether under
this Security Agreement or otherwise (including without limitation, reasonable
attorneys' fees and expenses for one firm of counsel), except for losses arising
from or out of Secured Party's or any Bank's gross negligence or willful
misconduct.

     8.   LIMITATION ON SECURED PARTY'S DUTY IN RESPECT OF COLLATERAL. Secured
Party shall deal with the Collateral in the same manner as it deals with similar
property for its own account. Secured Party shall be deemed to have acted
reasonably in the custody, preservation and disposition of any of the Collateral
if it takes such action as Grantor requests in writing, but failure of Secured
Party to comply with any such request shall not in itself be deemed a failure to
act reasonably and no failure of Secured Party to do any act not so requested
shall be deemed a failure to act reasonably.

     9.   REINSTATEMENT. This Security Agreement shall remain in full force and
effect and continue to be effective should any petition be filed by or against
Grantor for liquidation or reorganization, should Grantor become insolvent or
make an assignment for the benefit of creditors or should a receiver or trustee
be appointed for all or any significant part of Grantor's property and assets
and shall continue to be effective or be reinstated, as the case may be, if at
any time payment and performance of the Secured Obligations, or any part
thereof, is, pursuant to applicable law, rescinded or reduced in amount or must
otherwise be restored or returned by any obligee of the Secured Obligations,
whether as a "voidable preference," "fraudulent conveyance" or otherwise, all as
though such payment or performance had not been

                                                                              11

made. In the event that any payment, or any part thereof, is rescinded, reduced,
restored or returned, the Secured Obligations shall be reinstated and deemed
reduced only by such amount paid and not so rescinded, reduced, restored or
returned.

     10.  MISCELLANEOUS.

          10.1 No Waiver; Cumulative Remedies.

               (a)  Secured Party shall not by any act, delay, omission or
otherwise be deemed to have waived any of its respective rights or remedies
hereunder, nor shall any single or partial exercise of any right or remedy
hereunder on any one occasion preclude the further exercise thereof or the
exercise of any other right or remedy.

               (b)  The rights and remedies hereunder provided are cumulative
and may be exercised singly or concurrently and are not exclusive of any rights
and remedies provided by law.

               (c)  None of the terms or provisions of this Security Agreement
may be waived, altered, modified or amended except by an instrument in writing,
duly executed by Grantor and Secured Party.

          10.2 Releases.

               (a)  At such time as the Secured Obligations shall have been paid
and performed in full, the Collateral shall be released from the Liens created
hereby, and this Security Agreement and all obligations of Secured Party and
Grantor hereunder shall terminate, all without delivery of any instrument or
performance of any act by any party, and all rights to the Collateral shall
revert to Grantor. At the request and sole expense of Grantor following any such
termination Secured Party shall deliver to Grantor any Collateral held by
Secured Party hereunder, and execute and deliver to Grantor such documents as
Grantor shall reasonably request to evidence such termination.

               (b)  If any of the Collateral shall be sold, transferred or
otherwise disposed of by Grantor in a manner permitted by the Credit, then
Secured Party, at the request and sole expense of Grantor, shall execute and
deliver to Grantor all releases or other documents reasonably requested for the
release of the Liens created hereby on such Collateral.

               (c)  This Security Agreement and the security interests granted
herein shall remain in full force and effect and continue to be effective if at
any time payment and performance of the Secured Obligations, or any part
thereof, is, pursuant to applicable law, avoided, rescinded or reduced in
amount, or must otherwise be restored or returned by any obligee of the Secured
Obligations, whether as a "voidable preference," "fraudulent conveyance" or
otherwise, all as though such payment or performance had not been made. In the
event that any payment, or any part thereof, is avoided, rescinded, reduced,
restored or returned, the Secured Obligations and the security interests granted
herein shall be reinstated and the Secured Obligations shall be deemed reduced
only by such amount paid and not so avoided, rescinded, reduced, restored or
returned.

          10.3  Successor and Assigns. This Security Agreement and all
obligations of Grantor hereunder shall be binding upon the successors and
assigns of Grantor, and shall, together with the rights and remedies of Secured
Party hereunder, inure to the benefit of Secured Party, any future holder of any
of the indebtedness and their respective successors and assigns. No sales of
participations, other sales, assignments, transfers or other dispositions of any
agreement governing or instrument evidencing the Secured Obligations or any
portion thereof or interest therein shall in any manner affect the Lien granted
to Secured Party hereunder.

          10.4  Notices. Any notice or other communication hereunder to any
party shall be addressed and delivered (and shall be deemed given) in accordance
with the Credit Agreement to the addresses set forth on the signature page
hereof.

          10.5  Counterparts. This Security Agreement may be executed in any
number of separate counterparts, each of which, when so executed, shall be
deemed an original, and all of said counterparts taken together shall be deemed
to constitute but one and the same instrument.

          10.6  Severability. If any provision of this Security Agreement is
held to be unenforceable under applicable law for any reason, it shall be
adjusted, if possible, rather than voided in order to achieve the intent of the
parties to the extent possible. In any event, all other provisions of this
Security Agreement shall be deemed valid and enforceable to the fullest extent
possible under applicable law.

          10.7  Governing Law. In all respects, including all matters of
construction, validity and performance, this Security Agreement and the Secured
Obligations arising hereunder shall be governed by, and construed and enforced
in accordance with, the laws of the State of New York applicable to contracts
made and performed in such State.

Agreement to be executed and delivered by its duly authorized officer on the
