         THIS AMENDMENT NUMBER ONE TO LEASE AGREEMENT is entered into as of the
7th day of April, 2000, by and between THE PRUDENTIAL INSURANCE COMPANY OF
AMERICA, a New Jersey corporation ("Landlord") and EXACTIS.COM, INC., a Delaware
corporation ("Tenant").

                                    Recitals:

         A0 On or about January 19, 2000, Landlord and Tenant entered into a
written lease agreement (the "Lease") pertaining to approximately 46,418
rentable square feet of space, known as Suite 500 (the "Premises") located on
the 4th and 5th floors of the building known as Johns Manville Plaza, located at
717 - 17th Street, Denver, Colorado. (Initially capitalized terms not otherwise
defined herein have the same meaning as in the Lease.)

         B0 Landlord and Tenant now desire to amend the Lease in the manner and
form hereinafter set forth.

         NOW, THEREFORE, for good and valuable consideration, Landlord and
Tenant hereby agree as follows:

         1 The description of the Premises is amended by the addition of
approximately 37,045 rentable square feet of space, consisting of approximately
23,209 rentable square feet located in Suite 200 and 13,836 rentable square feet
located in Suite 310 (collectively, the "Additional Space"), as outlined on the
diagram of the 2nd and 3rd floors of the Building, attached hereto as Exhibit A
and made a part hereof by reference, for the term of the Lease on the following
basis:

                  A0 Tenant's right to occupy the Additional Space and its
obligations to pay Base Rent and Tenant's Pro Rata Share of increases in
Operating Expenses therefor commences on October 1, 2000 (the "Additional Space
Commencement Date") and terminates with the term of the Lease on February 28,
2010.

                  B0 Commencing on the Additional Space Commencement Date,
Tenant will pay Base Rent for the Additional Space in accordance with Paragraph
3 of the Lease in the following amounts:

                      ------                               -----------------

<S>                                                        <C>
         October 1, 2000-February 28, 2001                    $61,741.67
         March 1, 2001-February 28, 2002                      $64,828.75
         March 1, 2002-February 29, 2004                      $71,002,92
         March 1, 2004-February 28, 2006                      $77,177.08
         March 1, 2006-February 29, 2008                      $83,351.25
         March 1, 2008-February 28, 2010                      $89,525.42
</TABLE>

Base Rent for the Additional Space is in addition to Base Rent payable by Tenant
for the existing Premises.

                  C0 Commencing on the Additional Space Commencement Date and
thereafter, Tenant will pay its Pro Rata Share of increases in Operating
Expenses attributable to the Additional Space as determined in accordance with
Paragraph 5 of the Lease.

                  D0 Tenant has agreed to perform certain improvements in the
Additional Space. Such work will be completed and paid for in accordance with
and subject to the terms and provisions of the Work Letter, attached hereto as
Exhibit B. Except for in accordance with Exhibit B and the terms of the Lease,
Landlord is not obligated to improve or pay for improvements to the Additional
Space and Tenant accepts the Additional Space for the remainder of the term of
the Lease in its "as is" condition on the Additional Space Commencement Date.
Subject to the provisions of Exhibit B, any improvements by Tenant to the
Additional Space will be at Tenant's sole cost and expense and subject to the
provisions of the Lease.

                  E0 In addition to any spaces that Tenant has a right to use
pursuant to the Lease, Tenant shall have the right to use thirty-seven (37) in
and out unassigned parking space located in parking structures or surface lots
located on block 159 or 1801 California block, at the current rate charged for
such spaces from time to time, in accordance with and subject to Paragraph 29 of

<PAGE>   2

the Lease; provided, however, if Tenant fails to notify Landlord on or before
the Additional Space Commencement Date of its acceptance of the offered space or
fails to continuously lease the parking space, Tenant shall forfeit its rights
to the parking space but Tenant may thereafter at any time during the Lease Term
elect to lease such spaces on the terms set forth above upon 45 days' prior
written notice to Landlord. Except as set forth herein, the use of all parking
spaces shall be governed by Paragraph 29 of the Lease.

                  F0 The addition of the 3rd floor Additional Space satisfies
Tenant's rights to add space pursuant to Paragraph 7 of the Rider to the Lease
and Tenant has no further rights to add space pursuant to that Paragraph. The
addition of the 2nd floor space partially satisfies Tenant's rights under
Paragraph 8 of the Rider to the Lease.

                  G0 As of the Additional Space Commencement Date, any reference
to "Premises" in the Lease includes the Additional Space as a part of the
Premises and Tenant's occupancy thereof is subject to all terms of the Lease
except as otherwise specifically herein provided.

         2 Paragraph 10 of the Rider to the Lease is amended to provide that the
Options to extend the term of the Lease shall also apply to the Additional
Space.

         3 Tenant shall provide to Landlord, at the time of execution hereof by
Tenant, a clean, unconditional, irrevocable letter of credit from a lending
institution reasonably acceptable to Landlord in the form attached hereto as
EXHIBIT C (the "Letter of Credit") as a guaranty and security for the
performance of Tenant's obligations under this Lease on the following terms and
conditions:

                  A. It is understood and agreed that the Letter of Credit, or a
renewal or substitute therefor approved by Landlord, shall be kept in effect
from the date of execution of this Lease through September 30, 2003 (the "LC
Termination Date") in the form attached hereto as EXHIBIT C or in form otherwise
approved by Landlord. The initial Letter of Credit shall be in the amount of
$1,200,000.00 (the "LC Maximum"). On September 30, 2001, if the Letter of Credit
has not been presented for payment in accordance with this paragraph, the LC
Maximum shall be reduced by $400,000.00 (resulting in the Letter of Credit in
the amount of $800,000.00); if the Letter of Credit has not been presented for
payment in accordance with this paragraph by September 30, 2002, the LC Maximum
shall be reduced by an additional $400,000.00 (resulting in a Letter of Credit
in the amount of $400,000.00). The foregoing reductions shall not be applicable
if and so long as there is an ongoing Event of Default or Tenant is the subject
of a proceeding under any provision of federal or state law relating to
insolvency, bankruptcy, or reorganization at the time. If the Letter of Credit
would otherwise expire prior to the LC Termination Date, Tenant shall present
Landlord with an extension or renewal of the initial Letter of Credit, or a
substitute Letter of Credit in the same form as EXHIBIT C in the amount of the
then applicable LC Maximum, no later than thirty (30) days prior to the
expiration date of such initial Letter of Credit, from a lending institution
subject to Landlord's reasonable approval; such extension, renewal or substitute
Letter of Credit shall be effective no later than the day prior to the
expiration of the initial Letter of Credit and shall continue in effect for not
less than the period ending with the LC Termination Date and shall be in the
amount provided above. Tenant agrees that in an Event of Default by Tenant (as
defined in Section 19), Landlord shall have a right to present the Letter of
Credit (or the renewal, extension or substitute) for payment, with amounts
received to be held and applied in accordance with subparagraph B below. Any
failure of Tenant to provide Landlord with an extension, renewal or substitute
Letter of Credit, as required hereunder, shall be deemed an Event of Default
under the Lease and Landlord shall have a right to present the Letter of Credit
in accordance with the foregoing provision. If the Letter of Credit has not been
presented for payment in accordance with this Section on or before the LC
Termination Date, Landlord shall return the Letter of Credit to Tenant within
thirty (30) days after the LC Termination Date. Tenant agrees that in the event
of any transfer or mortgage, Landlord shall have the right to transfer the
Letter of Credit or substitute to the transferee or mortgagee, and if the Letter
of Credit has been duly transferred, Tenant shall look solely to such transferee
for the return of the Letter of Credit (or substitute). Landlord shall give
written notice to Tenant of transfer of Landlord's interest resulting in
transfer of the Letter of Credit. Landlord shall deliver the then-current
effective Letter of Credit to Tenant upon receipt of any conforming renewal or
substitute Letter of Credit provided in accordance with this Paragraph and
cooperate with the issuing bank to effect the release of such then-current
effective Letter of Credit.

                                       2
<PAGE>   3

                  B. If an Event of Default occurs or this Lease is terminated
pursuant to Section 19, Landlord may use, apply or retain all or any portion of
the amounts received under the Letter of Credit, if any, for the payment of any
rent or other charge in default or for the payment of any other sum to which
Landlord may become obligated by reason of Tenant's default, or to compensate
Landlord for any loss or damage which Landlord may suffer thereby in accordance
with Section 20 of the Lease. By the later of 60 days following the later of the
expiration of the Lease or Tenant's vacation of the Premises, any amounts drawn
upon the Letter of Credit that are not applied for payment of amounts in
accordance with the foregoing provision shall be returned to Tenant, without
payment of interest.

                  C. Landlord and Tenant agree that the annual fees charged by
the lending institution issuing the Letter of Credit (or any renewal, extension,
or substitute therefor) shall be paid by Tenant.

         4 Tenant hereby represents and warrants to Landlord that it has not
engaged or dealt with any broker other than Cushman & Wakefield of Colorado,
Inc., a Colorado corporation ("Cushman"), which has acted as Landlord's agent,
and CB Richard Ellis ("CB") which has acted as Tenant's agent, in connection
with the negotiation and/or execution of this leasing transaction. Each party
agrees to indemnify and save the other and Cushman harmless from any claim,
demand, damage, liability, cost or expense (including, without limitation,
attorney's fees) paid or incurred by either of them as a result of any claim for
brokerage or other commissions made by any broker, finder, or agent (other than
CB or Cushman), whether or not meritorious, by employment by Tenant or by reason
of claim made by, through or under the indemnifying party. Tenant acknowledges
that Landlord shall not be liable for the representations of Cushman or CB
regarding the Building, Premises or this lease transaction. Landlord shall be
responsible for the payment of all commissions to Cushman and CB pursuant to a
separate agreement with Cushman and CB.

         5 If there is any conflict between the terms and provisions of this
Amendment and the terms and provisions of the Lease or any prior amendments
thereto, the terms and provisions of this Amendment shall govern. Except as
herein specifically set forth, all other provisions of the Lease and any prior
amendments thereto shall remain in full force and effect and be binding upon the
parties in accordance with their terms.

         6 Time is of the essence herein.

         IN WITNESS WHEREOF, the parties have hereunto set their hands and seals
the day and year first above written.

XI.      GENERAL PROVISIONS

1.  ARBITRATION AND CHOICE OF FORUM

Any controversy or claim arising out of or relating to this contract, or the
breach thereof, shall be settled by arbitration administered by the American
Arbitration Association under its Commercial Arbitration Rules in the City of
New York, and judgment on the award rendered by the arbitrator(s) may be entered
in any court having jurisdiction thereof.

The parties acknowledge that any breach of this Agreement to arbitrate may cause
irreparable injury, and accordingly consent to the jurisdiction of the State and
Federal Courts located in the City of New York for any application to compel
specific performance of this Agreement to arbitrate.

In the event that any claim is found not to be arbitrable due to, inter alia, a
statutory policy precluding the arbitration of such claim, the parties consent
to the exclusive jurisdiction of the State and Federal Courts in the City of New
York for the adjudication of such claim.

2.  ASSIGNMENT

Agent shall not assign any right or interest under this Agreement (except for
monies due or to become due) nor delegate any activity or other obligation to be
performed or owed by Agent under this Agreement without the prior written
consent of BANSI. Agent shall advise BANSI as soon as possible if a change of
ownership of Agent is contemplated during the term of this Agreement. In the
event of an ownership change, BANSI reserves the right to terminate the existing
Agreement and at BANSI's sole discretion enter into a new Agreement with the new
ownership. Any attempted assignment or delegation in contravention of the above
shall be void and ineffective. Any assignment of monies shall be void and
ineffective to the extent that: (a) Agent shall not have given BANSI at least
thirty (30) days prior written notice of such assignment; or (b) such assignment
attempts to impose upon BANSI obligations to the assignee additional to payments
of such monies or to preclude BANSI from dealing solely and directly with Agent
in all matters pertaining to the Agreement. This Agreement may be assigned by
BANSI at any time without Agent's consent to any parent, subsidiary or affiliate
of BANSI.

                               AMENDMENT NO. 2 TO
                       THE BELL ATLANTIC AUTHORIZED AGENT

                      NETWORK SERVICES MARKETING AGREEMENT

          This Amendment No. 2 to the Bell Atlantic Authorized Agent Network
Services Marketing Agreement ("Agreement") is made this first day of January,
1999, by and between USTeleCenters, a Delaware corporation with principal
offices located at 745 Atlantic Avenue, Boston, MA 02111-2626 (hereinafter
referred to as "Agent"), and Bell Atlantic Network Services, Inc., a Delaware
corporation with principal offices located at 1310 North Court House Road,
Arlington, Virginia 2220l (hereinafter referred to as "BANSI").

          WHEREAS, BANSI and Agent are parties to the Agreement which authorizes
Agent to act as BANSI's non-exclusive agent for the marketing of Telephone
Company Services; and

          WHEREAS, BANSI and Agent intend for Agent to serve as both a
telemarketing agent as well as a premises agent for the states of Delaware, New
Jersey, Maryland, Pennsylvania, Virginia, Washington DC, West Virginia, New
York, New Hampshire, Massachusetts, Maine, Rhode Island and Vermont
("Telemarketing Area");

NOW, THEREFORE, THE PARTIES AGREE AS FOLLOWS:

          1. In the Telemarketing Area, Agent is authorized to make sales both
          through telemarketing and customer premises visits. Unless otherwise
          authorized in writing, Agent may not telemarket outside of the
          Telemarketing Area.

          2. When Agent is acting as a telemarketer, Agent shall proactively
          contact Customers over the telephone for purposes of closing a sale
          over the phone.

          3. When Agent is acting as a telemarketer, Agent shall comply with all
          guidelines, rules and principles established by BANSI, including,
          without limitation, the following:

          (a) Agent shall have the capability and all necessary equipment to
          provide, and shall provide, in-house and remote telephone monitoring
          (as specified by BANSI) of sales and marketing calls handled by Agent.
          BANSI shall have the right to monitor any calls remotely or otherwise
          without prior written notice to Agent.

          (b) Agent shall have the necessary technology to block, and shall
          block within forty-eight (48) hours of receiving a Do Not Contact List
          from BANSI, all telephone numbers included on that list which shall
          set forth the names and/or numbers of Customers who are not to be
          contacted by Agent for the marketing and sale of Services.

          (c) As prescribed by BANSI, Agent shall tape record and verify each
          sale or, in the alternative at BANSI's discretion, Agent shall provide
          a letter of authorization from a Customer authorizing Agent to place
          an order for purchase of Services on behalf of that Customer.

          (d) Agent shall submit to BANSI, for BANSI's prior approval, all call
          scripts and guides to be used by Agent in marketing or selling the
          Services.

          (e) Agent shall limit and manage the number of contacts with potential
          or actual Customers per year or quarter as instructed by BANSI, and
          shall report detailed calling activity hereunder to BANSI upon BANSI's
          request.

          IN WITNESS WHEREOF, each party has caused this Amendment No. 2 to the
Agreement to be executed by its duly authorized representative as of the date
