                         ARTICLE 3 - TERM AND POSSESSION

         3.01     TERM.

         This Lease shall be and continue in full force and effect for the term
set forth in Subsection 2.01(g). Subject to the remaining provisions of this
Article, the Term shall commence on the Target Commencement Date shown in
Subsection 2.01(h) and shall expire without notice to Tenant, on the Target
Expiration Date shown in Subsection 2.01(h); provided, however, that if the
Commencement Date is other than the first (1st) day of the month, the Expiration
Date shall nevertheless be the last day of the last month of the Term. Such
term, as it may be modified, renewed and extended, in accordance with EXHIBIT G
herein, is herein called the "Term".

         3.02     COMMENCEMENT.

         Subject to Section 3.03 hereof, if on the Target Commencement Date any
of the work described in this Lease that is required to be performed by Landlord
at Landlord's expense to prepare the Leased Premises for occupancy has not been
substantially completed, or if Landlord is unable to tender possession of the
Leased Premises to Tenant on the specified date due to any other reason beyond
the reasonable control of Landlord, the hereinafter defined Commencement Date
(and commencement of installments of Base Rent) shall be postponed until the
work to be performed in the Leased Premised at Landlord's expense is
substantially

                                       2
<PAGE>   4

completed, and the postponement shall operate to extend the Expiration Date in
order to give full effect to the stated duration of the Term. The deferment of
installments of Base Rent shall be Tenant's exclusive remedy for postponement of
the Commencement Date, and Tenant shall have no, and waives any, claim against
Landlord because of any such delay.

         3.03     TENANT'S DELAY.

         No delay in the completion of the Leased Premises resulting from delay
or failure on the part of Tenant in furnishing information or other matters
required in this Lease, and no delay resulting from the completion of work, if
any, that is to be performed at Tenant's expense pursuant to this Lease, shall
delay the Commencement Date, Expiration Date or commencement of payment of Rent
(as defined in Subsection 4.02 below).

         3.04     TENANT'S POSSESSION

         If, prior to the Commencement Date, Tenant shall enter into possession
of all or any part of the Leased Premises, the Term, the payment of monthly
installments of Base Rent and all other obligations of Tenant to be performed
during the Term shall commence on, and the Commencement Date shall be deemed to
be, the date of such entry; provided, no such early entry shall operate to
change the Expiration Date.

         3.05     CONFIRMATION OF DATES.

         Tenant shall confirm its acceptance of the Leased Premises by execution
of the Acceptance of Leased Premises Memorandum attached hereto as EXHIBIT B. If
either the actual commencement date ("Commencement Date") or actual expiration
date ("Expiration Date") are different from the Target Commencement Date and the
Target Expiration Date, respectively set forth in Subsection 2.01(h), Landlord
and Tenant shall execute an amendment to the Lease setting forth such actual
date. If such amendment is not executed, the Commencement Date and Expiration
Date shall be conclusively deemed to be the Target Commencement Date and the
Target Expiration Date set forth in Subsection 2.01(h).

         3.06     HOLDOVER.

         If Tenant shall remain in possession of the Leased Premises after the
expiration or earlier termination of this Lease, Tenant shall be deemed a
tenant-at-sufferance, terminable at any time on one (1) days' notice, and shall
pay daily rent at double the per day Rent payable with respect to the last full
calendar month immediately prior to the end of the Term or termination of this
Lease, but otherwise shall be subject to all of the obligations of Tenant under
this Lease. Tenant shall indemnify Landlord (i) against all claims for damages
by any other tenant to whom Landlord may have leased all or any part of the
Leased Premises effective upon the termination or expiration of this Lease, and
(ii) for all other losses, costs and expenses, including consequential damages
and reasonable attorneys' fees, sustained or incurred by reason of such holding
over.

                      ARTICLE 4 - RENT AND SECURITY DEPOSIT

         4.01     BASE RENT.

         Tenant agrees to pay to Landlord rent ("Base Rent") throughout the Term
in the amount of the Annual Base Rent set forth in Subsection 2.01(d), subject
to adjustment as provided in this

                                       3
<PAGE>   5

Lease. Base Rent shall be payable in monthly installments in the amount set
forth in Subsection 2.01(d) ("Monthly Base Rent") in advance and without demand,
deduction or set-off, on the first day of each and every calendar month during
the Term. If the Commencement Date is not the first day of a month, Tenant shall
be required to pay on the Commencement Date a pro rata portion of the Monthly
Base Rent for the first partial month of the Term.

         4.02     PAYMENT OF RENT.

         As used in this Lease, "Rent" shall mean the Base Rent, Additional Rent
(defined below) and all other amounts required to be paid by Tenant in this
Lease. The Rent shall be paid at the times and in the amounts provided herein in
legal tender of the United states of America to Landlord at its address
specified in Subsection 2.01(k) above or at such other address as Landlord may
from time to time designate in writing. The Rent shall be paid without notice,
demand, abatement, deduction or offset except as may be expressly set forth in
this Lease.

         4.03     ADDITIONAL RENT.

         The term "Additional Rent" shall mean the total of the "Operating
Expense Adjustment", the "Cost of Living Adjustment", as such terms are defined
below, and any other amounts in addition to Base Rent which Tenant is required
to pay to Landlord under this Lease.

         4.04     OPERATING EXPENSE ADJUSTMENT.

         If the Expense (defined below) for the Building for any calendar year,
expressed on a per square foot basis, exceed the Base Operating Expense Factor
specified in Subsection 2.01(e), Tenant shall pay to Landlord increased Rent (an
"Operating Expense Adjustment") in an amount equal to the product of such excess
times the square feet of the Leased Premises as stated in Subsection 2.01(b).
The Operating Expense Adjustment shall be payable in monthly installments on the
first day of each calendar month based on Landlord's estimate of the Operating
Expenses for the then current calendar year. Landlord may at any time give
Tenant written notice specifying Landlord's estimate of the Operating Expenses
for the then current calendar year or the subsequent calendar year and
specifying the Operating Expense Adjustment to be paid by Tenant for each such
year. Within one hundred twenty (120) days after the end of each calendar year,
Landlord shall give written notice to Tenant specifying the actual Operating
Expenses for the prior calendar year and any necessary adjustment to the
Operating Expense Adjustment paid by Tenant for that calendar year. Tenant shall
pay any deficit amount to Landlord within fifteen (15) days after receipt of
Landlord's written notice. Any excess payment by Tenant for the prior calendar
year shall reduce the Operating Expense Adjustment for the following year. The
provisions of this paragraph shall survive the cancellation or termination of
this Lease.

         The term "Operating Expenses" shall mean, except as otherwise specified
in this definition, all expenses, costs, and disbursements of every kind and
nature, computed on an accrual basis, which Landlord shall pay or become
obligated to pay because of or in connection with the ownership and operation of
the Building, or Landlord's efforts to reduce Operating Expenses, including
without limitation: (1) wages and salaries of all employees to an extent
commensurate with such employees' involvement in the operation, repair,
replacement, maintenance, and security of the Building, including, without
limitation, amounts attributable to

                                       4
<PAGE>   6

the employer's Social Security Tax, unemployment taxes, and insurance, and any
other amount which may be levied on such wages and salaries, and the costs of
all insurance and other employee benefits related thereto; (2) all supplies and
materials used in the operation, maintenance, repair, replacement and security
of the Building; (3) the rental costs of any and all leased capital improvements
and the annual costs of any and all capital improvements made to the Building
which, although capital in nature, can reasonably be expected to reduce the
normal operating costs of the Building, to the extent of the lesser of such
expected reduction in operating expenses or the annual cost of such capital
improvements, as well as all capital improvements made in order to comply with
any legal requirement hereafter promulgated by any government authority relating
to the environment, energy, conservation, public safety, access for the disabled
or security, as amortized over the useful life of such improvements by Landlord
for federal income tax purposes; (4) the cost of all utilities, other than the
cost of electricity supplied to tenants of the Building which is separately
metered and reimbursed to Landlord by such tenants; (5) the costs of all
maintenance and service agreements with respect to the operation of the Building
or any part thereof, including, without limitation, management fees, alarm
service, equipment, window cleaning, elevator maintenance, landscape maintenance
and parking area maintenance and operation; (6) the costs of all insurance
relating to the Building, including without limitation, casualty and liability
insurance applicable to the Building and Landlord's personal property used in
connection therewith; (7) all taxes and assessments and government charges,
whether federal, state, county, or municipal, and whether by taxing districts or
authorities presently taxing or by others, subsequently created or otherwise,
including all taxes levied or assessed against or for leasehold improvements and
any other taxes and assessments attributable to the Building and/or the
operation thereof, together with the reasonable costs (including attorneys,
consultants and appraisers) of any negotiation, contest or appeal pursued by
Landlord in an effort to reduce any such tax, assessment or charge, excluding,
however, federal and state taxes on Landlord's income, but including all rental,
sales, use and occupancy taxes or other similar taxes, if any, levied or imposed
by any city, state, county, or other governmental body having jurisdiction; and
(8) the cost of all repairs, replacements, removals and general maintenance with
respect to the Building. Specifically excluded from Operating Expenses are
expenses for capital improvements made to the Building, other than capital
improvements described in clause (3) of this definition and except for items
which, through capital for accounting purposes, are properly considered
maintenance and repair items, such as painting of common areas, replacement of
carpet in elevator lobbies and like items; expenses for repair, replacement and
general maintenance paid by proceeds of insurance or by Tenant or other third
parties; alterations attributable solely to tenants of the Building other than
Tenant; depreciation of the Building; leasing commissions; and federal and state
income taxes imposed on Landlord.

         If, during all or part of any calendar year, the Building is less than
95% occupied, or if Landlord is providing less than 95% of the Building with any
item or items of work or service which would constitute an Operating Expense
hereunder, then the amount of the Operating Expenses for such period shall be
adjusted to include any and all items enumerated under the definition of
Operating Expenses set forth in this Subsection which Landlord reasonably
determines Landlord would have incurred if the Building had been at least 95%
leased and occupied with all tenant improvements constructed or if Landlord has
been providing such item or items of work or service to at least 95% of the
Building. If the actual occupancy of the

                                       5
<PAGE>   7

Building is between 95% and 100%, then the actual occupancy percentage shall be
used for this computation.

         4.05     COST OF LIVING ADJUSTMENT.

         At the end of each Lease year during the Term, the Monthly Base Rent
for the following Lease year shall be increased in accordance with the following
formula:

         (Annual Base Rent for the current Lease year x 1.03) / by twelve =
Monthly Base Rent for the following Lease year.

         The resulting figure will be the Monthly Base Rent for the following
year, and Tenant shall adjust its payments of Monthly Base Rent accordingly
beginning on the first day of the first month in the following Lease year.

         4.06     INTENTIONALLY DELETED.

         4.07     LATE CHARGE.

         If Tenant fails or refuses to pay any installment of Rent when due,
Landlord, at Landlord's option, shall be entitled to collect a late charge of

payment of Rent in each calendar year of the Term, which late payment shall not
be subject to a late charge hereunder so long as the Rent then due is paid

intention of Landlord and Tenant, the late charge shall be limited to the
maximum amount of interest that lawfully may be collected by Landlord under
applicable law, and if any payment is determined to exceed such lawful amount,

hereunder. If all Rent hereunder has been paid in full, any excess shall be
refunded to Tenant. Tenant shall reimburse Landlord for any processing fees
charged to Landlord as a result of Tenant's checks having been returned for

         9.06     ATTORNMENT.

         If any ground or similar lease or mortgage is terminated or foreclosed,
Tenant shall, upon request, attorn to the landlord under such lease or the
mortgagee or purchaser at such foreclosure sale, as the case may be, and execute

the foregoing, in no event shall Tenant assign this Lease or sublease the Leased
Premises to any entity engaged in the commercial real estate business,
including, without limitation, property management or the brokerage, ownership

any further assignment or sublease. If Tenant desires to assign this Lease or
sublet the Leased Premises or any part thereof, Tenant shall give Landlord
written notice of such desire at least sixty (60) days in advance of the date on
which Tenant desires to make such assignment or sublease, together with a
non-refundable fee of Seven Hundred Fifty Dollars ($750.00) (the "Transfer
Fee"). Landlord shall then have a period of thirty (30) days following receipt
of such notice within which to notify Tenant in writing that Landlord elects (a)
to terminate this Lease as to the space so affected as of the date so specified
by Tenant, in which event Tenant shall be relieved of all further obligations
hereunder as to such space, or (b) to permit Tenant to assign this Lease or
sublet such space (provided, however, if the rent agreed upon between Tenant and
subtenant is greater than the Monthly Base Rent that Tenant must pay Landlord,
such excess rent shall be deemed additional rent owed by Tenant and payable to
Landlord in the same manner that Tenant pays the Rent hereunder), or (c) to
refuse to consent to Tenant's assignment or subleasing such space and to
continue this Lease in full force and effect as to the entire Leased Premises.
If Landlord shall fail to notify Tenant in writing of such election within the
thirty (30) day period, Landlord shall be deemed to have elected option (c)
above. Tenant agrees to pay Landlord's actual reasonable attorneys' fees
associated with Landlord's review and documentation of any requested assignment
or sublease hereunder regardless of whether Landlord consents to any such
assignment or sublease. No assignment or subletting by Tenant shall relieve
Tenant of any obligations under this Lease, and Tenant shall remain fully liable
hereunder. If Tenant is not a public company that is registered on a national
stock exchange or that is required to register its stock with the Securities and
Exchange Commission under Section 12(g) of the Securities and Exchange Act of
1934, any change in a majority of the voting rights or other controlling rights
or interests of Tenant shall be deemed an assignment for the purposes hereof.

         Subject to the provisions of Section 5.01 of the Lease and excluding
holidays, Landlord will furnish Building standard heating, ventilating and air
conditioning between 8:00 a.m. and 6:00 p.m. on weekdays (from Monday through
Friday, inclusive) and Saturdays between 8:00 a.m. and 1:00 p.m. Upon request of
Tenant made in accordance with the rules and regulations for the Building,
Landlord will furnish air conditioning and heating at other times (that is, at
times other than the times specified above), in which event Tenant shall
reimburse Landlord for furnishing such services on the following basis:

         Tenant shall reimburse Landlord at the rate of Thirty-five and No/100
Dollars ($35.00) per hour per air handling unit which is activated to provide
the requested air conditioning or heating service; provided, such rate is based
upon the "Kilowatt Hour rate" (as hereinafter defined) for electricity as of
January 1, 1995 (the "Base Rate"), and if and when the Kilowatt Hour Rate
increases over the Base Rate, the aforesaid rate of Thirty-five and No/100
Dollars ($35.00) per hour per air handling unit thereof shall automatically
increase proportionately. For example, if the Kilowatt Hour Rate increases by
10% over the Base Rate, said rate shall automatically increase by 10%. The
"Kilowatt Hour Rate" shall mean the actual average cost per kilowatt hour
charged by the public utilities providing electricity to the Building, or if
said public utilities shall cease charging for electricity on the basis of a
kilowatt hour, the Kilowatt Hour Rate shall mean the actual average cost per
equivalent unit of measurement substituted therefor by said public utilities.
The Base Rate is hereby stipulated to be $.0600 per kilowatt hour.

         throughout the portion of the Term of the Lease that has expired prior
         to the exercise of the Renewal Option and Tenant is not in default of
         any of the terms or conditions of the Lease at the time Tenant notifies
         Landlord of its election to renew the Term of the Lease or at the time

         of the terms or conditions of the Lease; and

lots, Landlord shall be responsible for providing Tenant with an equivalent
number of parking spaces at a location to be mutually agreed upon by Landlord
and Tenant, with Landlord responsible for any increased cost due to the

NORTH CAROLINA

WAKE COUNTY                                  LEASE MODIFICATION AGREEMENT NO. 1

         THIS LEASE MODIFICATION AGREEMENT NO. 1 (the "Agreement") is made and
entered into this 23rd day of March, 2000 (the "Execution Date"), by and between
PHOENIX LIMITED PARTNERSHIP OF RALEIGH, a Delaware limited partnership
("Landlord"), and HIGH SPEED NET SOLUTIONS, INC., a Florida corporation
("Tenant").

                                   WITNESSETH:

         WHEREAS, Landlord and Tenant entered into that certain Lease Agreement
dated October 15, 1999 (the "Lease"), pursuant to which Tenant leased
approximately 1,911 square feet of office space designated as Suite 2120 (the
"Current Premises") in the building known as Two Hannover Square, Raleigh, North
Carolina 27601 (the "Building). The Lease is incorporated herein by reference in
its entirety. Terms used and not otherwise defined herein shall have the meaning
ascribed to them in the Lease.

         WHEREAS, Tenant desires to expand into larger premises in the Building
and Landlord agrees to such expansion, provided, however, Tenant must relocate
to alternative space on the twenty-first (21st) floor of the Building in order
for Landlord to accommodate Tenant's desire; and

         WHEREAS Landlord and Tenant desire to terminate Tenant's lease
obligations with regard to the Current Premises and to relocate Tenant to new
premises in the Building, upon the terms and conditions contained herein.

         NOW, THEREFORE, in consideration of the premises, rent, mutual
covenants and conditions contained herein, and other good and valuable
consideration, the receipt and sufficiency of which are acknowledged, Tenant and
Landlord hereby agree as follows:

         1. BASIC LEASE PROVISIONS. SECTION 2.01 of the Lease is amended to
reflect that, effective as of May 1, 2000 (the "Target Relocation Date"), Tenant
shall, at its sole cost and expense, relocate to new Leased Premises containing
approximately 4,874 square feet of office space designated as Suite 2120 in the
Building (the "Relocated Premises") as further described on the attached EXHIBIT
A-1-A, which is attached hereto and made a part hereof by reference in its
entirety. Effective as of the Commencement Date for Relocated Premises (as
hereinafter defined), SECTION 2.01 of the Lease shall be amended as follows:

                  (i) SUBSECTION 2.01(B) of the Lease (Floor/Suite/Square Feet)
                  is amended by substituting the Relocated Premises for the
                  Current Premises. Therefore, the third line of SUBSECTION
                  2.01(B) is amended by deleting the Square Feet Area of "1,911"
                  and inserting the Square Feet Area of "4,874" in lieu thereof;

                  (ii) SUBSECTION 2.01(D) of the Lease (Base Rent) is amended to
                  reflect the Base Rent for the Relocated Premises. Therefore,
                  SUBSECTION 2.01(D) of the Lease shall be amended by deleting
                  the amounts currently set forth therein and inserting the
                  following Base Rent chart in lieu thereof:

                           (Base Rent chart appears on the following page.)

                  Notwithstanding the foregoing, Tenant shall also continue to
                  be responsible for Additional Rent payments under the Lease";

                  (iii) SUBSECTION 2.01(G) of the Lease (Term) is amended to
                  reflect one (1) additional year added to the Term of the
                  Lease. Therefore, the number "5" shall be deleted therefrom
                  and the number "6" shall be inserted in lieu thereof; and

                  (iv) SUBSECTION 2.01(H) of the Lease (Commencement and
                  Expiration Dates) is amended to reflect that the "Commencement
                  Date for the Relocated Premises" shall be the earlier of (A)
                  the Target Relocation Date (May 1, 2000), or (B) the date the
                  Relocated Premises is substantially complete (defined as the
                  date of issuance by the City of Raleigh of a certificate of
                  occupancy), and Tenant shall confirm the actual Commencement
                  Date for the Relocated Premises by execution of the Acceptance
                  of Relocated Premises Memorandum attached hereto as EXHIBIT
                  B-1-A. The Expiration Date for the Relocated Premises shall be
                  the Expiration Date of the Lease, as amended, (September 30,
                  2005). Landlord and Tenant acknowledge and agree that the
                  Relocated Premises shall be deemed the "Leased Premises" for
                  all purposes after the Commencement Date for the Relocated
                  Premises.

                  Effective as of 12:00 midnight on the day prior to the
Commencement Date for Relocated Premises (the "Vacate Date"), and contingent

(21st) floor of the Building (the "Relocated Premises"), which Relocated
Premises was also designated as Suite 2120. (The Original Lease and Amendment
No. 1 are incorporated herein by reference in their entirety and hereinafter
collectively referred to as the "Lease". Terms used and not otherwise defined
herein shall have the meaning ascribed to them in the Lease.); and

         WHEREAS, Tenant did not move to the Relocated Premises on May 1, 2000,
but moved to the Relocated Premises effective as of June 12, 2000 ("Tenant's
Relocation Date"); and

         WHEREAS, Tenant desires to expand back into the Original Premises, and
Landlord agrees to such expansion; and

         WHEREAS Landlord and Tenant desire to modify the Lease by (i) setting
forth Tenant's Relocation Date, and (ii) expanding Tenant's obligations with
regard to the Lease for an additional 1,911 square feet of space comprising the

         NOW, THEREFORE, in consideration of the premises, rent, mutual
covenants and conditions contained herein, and other good and valuable
consideration, the receipt and sufficiency of which are acknowledged, Tenant and
Landlord hereby agree as follows:

         1. BASIC LEASE PROVISIONS. SECTION 2.01 of the Lease is amended to
reflect that, effective as of the Execution Date, Landlord shall let, lease and
demise to Tenant the approximate 1,911 square feet of office space on the
twenty-first (21st) floor in the Building that was the Original Premises
("Expansion No. 1") as further described on the attached EXHIBIT A-1-B, which is

                  (i) SUBSECTION 2.01(B) of the Lease (Floor/Suite/Square Feet)
                  is amended by the addition of Expansion No. 1. Therefore, the
                  third line of SUBSECTION 2.01(B) is amended by deleting the
                  Square Feet Area of "4,874" and inserting the Square Feet Area
                  of "6,785" in lieu thereof;

                  (ii) SUBSECTION 2.01(D) of the Lease (Base Rent) is amended to
                  reflect the addition of Expansion No. 1 to the Base Rent. Base
                  Rent for Expansion No. 1 shall be calculated at Eighteen
                  Dollars and Fifty Cents ($18.50) per square foot per annum,
                  with such Base Rent for Expansion No. 1 escalating by Fifty
                  Cents ($.50) per square foot per annum, each Lease Year during
                  the Term ("Lease Year" shall mean that twelve-month period
                  from October 1st through the following September 30th of each
                  year of the Term). Notwithstanding the foregoing, the Base
                  Rent escalation for Expansion No. 1 (and not for the remainder
                  of the Leased Premises) (i) shall not be subject to the
                  provisions of SECTION 4.05 of the Lease, and (ii) shall not
                  commence until October 1, 2001. Therefore, SUBSECTION 2.01(D)
                  of the Lease shall be amended by deleting Base Rent chart
                  currently set forth therein and inserting the following Base
