         WHEREAS, pursuant to a Lease dated as of July 30, 1990 between

         WHEREAS, pursuant to an Assignment of Lease and Consent to Assignment
Agreement ("Assignment") dated April 14, 1997 between Toomey and Sublessor,
Toomey assigned its rights as Lessee under the Lease to Sublessor.

         WHEREAS, Sublessee desires to sublet from Sublessor a portion of the
Premises referred to in the Lease.

         NOW, THEREFORE, the parties hereto, for themselves, their successors
and assigns, mutually covenant and agree as follows:

         1 . SUBLET PREMISES. Sublessor does hereby sublease to Sublessee and
Sublessee does hereby sublease from Sublessor, for the term and upon the
conditions hereinafter provided, the Sublet Premises, being an area of
approximately 12,399 square feet of rentable floor area on the fourth (4th)
floor, known as Suite 400 of the Framingham Office Park, 1671 Worcester Road,

per week, without prior notification of any person or party and shall be

and the like which would affect Sublessee's ability to access the Sublet
Premises at any time.

         2. TERM. The term of this Sublease shall commence on October 15, 1997
and shall end at 11:59 p.m. on September 30, 2000, or on such earlier date upon
which said term may expire or be terminated pursuant to a termination of the
Lease or any of the conditions or limitations or other provisions of this
Sublease or pursuant to law. In the event Landlord has not consented to this
Agreement by October 15, 1997, provided Landlord's failure to consent is not
caused by an issue within Sublessee's control other than Sublessee's refusal to
alter a material term or condition of this Sublease, Sublessee shall receive one
(1) free day of rent for each day thereafter that Landlord has not consented;
provided, however, that Sublessee shall have the right to terminate this
Sublease if Landlord has not consented by November 1, 1997. Sublessor shall


<PAGE>   2


have the right to terminate this Sublease if Landlord fails to consent by
November 8, 1997, and Sublessee has not yet terminated. Notwithstanding anything
in this Sublease to the contrary, Sublessee acknowledges and agrees that all
provisions of the Lease with respect to Sublessor's Option to Extend (as
described in Section 40 of the Lease) shall not operate for the benefit of
Sublessee and may not be enforced by Sublessee, except as may be otherwise
expressly agreed in writing by Sublessor and Sublessee. Sublessor agrees that
Sublessee shall have reasonable access to the Sublet Premises on prior notice to
Sublessor for the purpose of installing, repairing, and/or upgrading utilities
and telecommunications systems at the Sublet Premises from the date Landlord
consents to this Agreement and Sublessee presents a certificate of insurance
acceptable to Sublessor.

         3. RENT. During the term of this Sublease, the rent payable by
Sublessee shall be the sum of Sixteen Thousand Five Hundred Thirty-two Dollars
($16,532.00), consisting of the following:

                  Year One:   Base rent of $14.00 per square foot ("Base Rent"),
                              plus a $2.00 per square foot charge for operating
                              expenses, real estate taxes and reimbursement of
                              lease transaction costs ("Additional Rent").

                  Years Two
                  and Three:  Base Rent of $15.00 per square foot, plus a $1.00
                              per square foot charge for Additional Rent.

         Notwithstanding anything in this Sublease to the contrary, Base Rent
and Additional Rent shall begin to accrue on November 1, 1997, and continue
thereafter on the first day of each and every calendar month during the term of
this Sublease. All payments of Base Rent and Additional Rent shall be paid to
Sublessor in advance of each month for which such rent is due.

         Within three (3) days of Landlord's consent to this Sublease, but in no
event later than the date of occupancy, the installments of rent for the first
and last months of the term of this Sublease shall be paid by Sublessee.
Sublessor shall hold all moneys paid to it by Sublessee as prepaid rent in an
interest-bearing account, segregated from Sublessor's other assets and shall pay
all interest accruing thereon annually to Sublessee.

         If the obligation of Sublessee to pay rent hereunder begins on a day
other than on the first day of a calendar month, rent from such date until the
first day of the following calendar month shall be prorated at the rate of
one-thirtieth (1/30th) of the monthly installment for each day payable in
advance. The monthly Base Rent, Additional Rent and any other charges herein
reserved or payable shall be paid to Sublessor at the address specified in
Section 22 hereof, or at such other place as Sublessor may designate in writing,
in lawful money of the United States of America without demand therefor and
without any deduction, set-off or abatement whatever.

         4. REAL ESTATE TAXES AND OPERATING COSTS. Sublessee agrees to pay
Sublessor, as Additional Rent under this Sublease, Sublessee's pro rata share,
of (i) the amount by which the actual real estate taxes for the applicable
fiscal year exceed the real estate taxes for the base year

                                      -2-

<PAGE>   3


and (ii) the amount by which the operating expenses for the applicable operating
year exceed the operating expenses for the base year. The base year shall be
fiscal year 1997 for purposes of computing any increase in real estate taxes and
calendar year 1997 for purposes of computing any increase in operating expenses.
Sublessee's pro rata share shall equal the square footage of the Sublet Premises
divided by the aggregate of all the rentable square footage (whether or not
rented or improved) within the building. Sublessee shall be responsible for
paying all utility charges in respect of the Sublet Premises, including without
limitation any charges for electricity related to the Sublet Premises. Sublessee
shall also pay to Sublessor, as Additional Rent, all charges for any additional
services requested by and provided to Sublessee, including, without limitation,
charges and fees for after-hours heating and air-conditioning services pursuant
to Section 12 of the Lease, or as may otherwise be agreed between Sublessee and
Landlord. Any Additional Rent which may be payable to Sublessor shall be
apportioned during the year in which the term of this Sublease commences and
during the year in which such term shall end, such that Sublessee shall be
obligated to pay a proportionate share of such Additional Rent which is
attributable to the number of days of their term hereof which are included in
the period for which such Additional Rent is payable by Sublessor under the
Lease. Sublessee shall pay Additional Rent within thirty (30) days of receipt of
this statement. Sublessee's obligations to pay Additional Rent shall survive the
termination of this Sublease.

         5. AFTER HOURS AIR-CONDITIONING AND HEATING. Landlord and Sublessor
hereby acknowledge and agree that the Lease is hereby amended to reflect the
parties' agreement that air-conditioning, heating and ventilation shall be

and from 8:00 AM to 1:00 PM on Saturdays and that the cost of any additional
air-conditioning, heating and/or ventilation requested by the Sublessee for the
Sublet Premises shall be fixed at the rate of Ten Dollars ($10.00) per hour.

         6. SECURITY DEPOSIT. Upon execution of this Sublease, Sublessee shall
pay to Sublessor the sum of Sixteen Thousand Five Hundred and Thirty-two Dollars
($16,532.00), and within three days of the date Landlord consents to this
Sublease, Sublessee shall pay to Sublessor an additional sum of Sixteen Thousand
Five Hundred and Thirty-two Dollars ($16,532.00) as security (the "Security
Deposit) for the faithful performance by Sublessee of its obligations hereunder.
The Security Deposit shall be paid to Sublessor in cash. In the event of an
Event of Default (as defined in Section 19 hereof), Sublessee hereby authorizes
Sublessor, at Sublessor's election (with notice to Sublessee) and with or
without terminating this Sublease and without prejudice to any other right or
remedy Sublessor may have, to apply all or any portion of the Security Deposit
necessary to remedy such default. If said Security Deposit or portion thereof is
so applied, Sublessee, upon demand by Sublessor, shall within seven (7) days
after written notice therefor from Sublessor, deposit with Sublessor an amount
equal to the amount of the Security Deposit so applied. Any unapplied cash
portion of the Security Deposit shall be held by Sublessor in a separate escrow
account and interest earned thereon shall be paid to Sublessee on an annual
basis. On November 1, 1998, a payment in an amount equal to one (1) month's rent
(including any Additional Rent) shall be deducted from the Security Deposit and
applied towards Sublessee's obligations hereunder without any objection on the
part of Sublessor or demand to reinstate such portion of the Security Deposit so
applied, provided that Sublessee has never been and is not currently in default
under this Agreement. Any portion of the Security Deposit

                                      -3-

remaining at the end of the term of this Sublease shall be refunded to
Sublessee.

          7. USE; SIGNS. Sublessee will use and occupy the Sublet Premises

same is consistent with the size, design and quality of the existing sign and
such sign complies with all applicable zoning laws.

          8. CONDITION OF SUBLET PREMISES. Sublessee hereby acknowledges that
the Sublet Premises are hereby subleased in an as is condition, without any
representations or warranties made on the part of Sublessor; provided, however,

material defects to or in the Sublet Premises which have not been previously

equipment and that in the event such refrigerator is not removed prior to the
date Landlord consents to the Sublease, Sublessee shall be entitled to an
abatement of rent equal to the number of days for which it remains at the Sublet
Premises.

          9. ALTERATIONS. In connection with the execution of this Sublease,
Sublessee shall not make any structural alterations or additions to the Sublet
Premises, but may make non-structural alterations (the "Sublessee Alterations")

the Landlord's consent in accordance with the terms of the Lease. All such
Sublessee Alterations shall be at Sublessee's sole cost and expense and shall be

unreasonably withheld or delayed.

         If any Sublessee Alterations are made without Landlord's consent,
Landlord may remove the same, and may correct, repair and restore the Sublet
Premises and any damage arising from such removal, and Sublessee shall be liable

the extent of the then remaining balance of the term of this Sublease, Sublessee
and Landlord shall, except as provided herein, have the same respective rights
and obligations as Sublessee and Sublessor have under this Sublease. If Landlord
shall so succeed to the interest of Sublessor under this Sublease by reason of
the termination of the Lease, or by any other manner, Landlord shall be bound to
Sublessee under this Sublease, and Sublessee shall have the same rights and
remedies against Landlord for the breach of an agreement contained in this
Sublease that Sublessee would have had under this Sublease against Sublessor if
Landlord had not succeeded to the interest of Sublessor; provided, however,
Landlord shall not be:

         (a)      liable for (or be responsible for any cure or costs of cure
                  of) any default or any act or omission of Sublessor, including
                  any continuing condition that arose as a result of any such
                  act or omission or otherwise prior to Landlord succeeding to
                  Sublessor; or

         (b)      subject to any offsets or defenses which Sublessee might have
                  against Sublessor; or

         (d)      bound by any amendment or modification of this Sublease made
                  without Landlord's written consent; or

         (e)      liable for or on account of any security deposit or other sums

         20. ENTIRE AGREEMENT. This Sublease, together with those provisions of
the Lease applicable hereto, contains all of the covenants, agreements, terms,
provisions, conditions, warranties and understandings relating to the leasing of
the Sublet Premises and Sublessor's obligations in connection therewith, and
neither Sublessor nor any agent or representative of Sublessor has made or is
making, and Sublessee in executing and delivering this Sublease is not relying
upon, any warranties, representations, promises or statements whatsoever, except
to the extent expressly set forth in this Sublease. The failure of Sublessee or
Sublessor to insist in any instance upon the strict keeping, observance or
performance of any covenant, agreement, term, provision or condition of this
Sublease or to exercise any election herein contained shall not be construed as
a waiver or relinquishment for the future of such covenant, agreement, term,
provision, condition or election, but the same shall continue and remain in full
force and effect. No waiver or modification of any covenant, agreement, term,
provision or condition of this Sublease shall be deemed to have been made unless
expressed in writing and signed by Landlord, Sublessee and Sublessor. No
surrender of possession of the Sublet Premises or of any part thereof by
Sublessee or of any remainder of the term of this Sublease shall release
Sublessee from any of its obligations hereunder unless accepted by Sublessor in
writing. The receipt and retention by Sublessor of monthly Base Rent or
Additional Rent from anyone other than Sublessee shall not be deemed a waiver of
the breach by Sublessee of any covenant, agreement, term or provision of this
Sublease, or as the acceptance of such other person as a tenant, or as a release
of Sublessee from the further keeping, observance or performance by Sublessee of
the covenants, agreements, terms, provisions and conditions herein contained.
The receipt and retention by Sublessor of monthly Base Rent or Additional Rent
with knowledge of the breach of any covenant, agreement, term, provision or
condition herein contained shall not be deemed a waiver of such breach.

         21. SUCCESSORS AND ASSIGNS. The obligations of this Sublease shall bind
and benefit the successors and permitted assigns of the parties with the same
effect as if mentioned in each instance where a party hereto is named or
referred to.

                               FIRST AMENDMENT TO
                               SUBLEASE AGREEMENT
                               ------------------


         WHEREAS, Merkert Enterprises, Inc., a Massachusetts corporation
("SUBLESSOR") and Nova Link USA Corporation, a Massachusetts corporation
("SUBLESSEE") have entered into a certain Sublease Agreement (the "Sublease");
and

         WHEREAS, the parties now wish to modify certain provisions thereof';

         NOW, THEREFORE, for good and valuable consideration, the receipt and
sufficiency of which is hereby acknowledged, the parties agree as follows:

         1. DEEMED CONSENT. The parties agree that that certain letter from
Landlord (as defined in the Sublease) dated October 30, 1997 shall be deemed to
be Landlord's consent as contemplated by Paragraphs 2 and 3 of the Sublease. As
between Sublessor and Sublessee, Landlord shall be deemed to have consented as
of the date of execution of this First Amendment by both parties hereto (the
"DEEMED CONSENT DATE");

         2. SECURITY DEPOSIT. Paragraph 6 of the Sublease is hereby amended by
the deletion and the replacement thereof with the following:

              6. SECURITY DEPOSIT. Sublessor hereby acknowledges receipt from
              Sublessee of the sum of Sixteen Thousand Five Hundred and
              Thirty-two Dollars ($16,532.00) as security (the "Security
              Deposit") for the faithful performance by Sublessee of its
              obligations hereunder. In the event of an Event of Default (as
              defined in Section 19 hereof), Sublessee hereby authorizes
              Sublessor, at Sublessor's election (with notice to Sublessee) and
              with or without terminating this Sublease and without prejudice to
              any other right or remedy Sublessor may have, to apply all or any
              portion of the Security Deposit necessary to remedy such default.
              If said Security Deposit or portion thereof is so applied,
              Sublessee, upon demand by Sublessor, shall within seven (7) days
              after written notice therefor from Sublessor, deposit with
              Sublessor an amount equal to the amount of the Security Deposit so
              applied. Any unapplied cash portion of the Security Deposit shall
              be held by Sublessor in a separate escrow account and interest
              earned thereon shall be paid to Sublessee on an annual basis. On
              December 1, 1998, the Security Deposit, together with any interest
              accrued thereon, shall be applied towards Sublessee's obligations
              hereunder without any objection on the part of Sublessor or demand
              to reinstate the Security Deposit as so applied.

         3. RENT COMMENCEMENT. The parties agree that Sublessee's obligation to
pay rent, as set forth in Paragraph 3 of the Sublease, shall commence on the
first business day which is at least fifteen ( 15) days after the Deemed Consent
Date.

         4. WAIVER OF RIGHT TO TERMINATE. Each party hereby waives any right it
may have or have had pursuant to the provisions of Paragraph 2 of the Sublease
to terminate the Sublease for Landlord's failure to consent within the allotted
time set forth therein.

         IN WITNESS WHEREOF, Sublessee and Sublessor have duly executed this
Sublease as of this _____ day of November, 1997.
