                                  AMENDMENT 17

                         AT&T Frame Relay Plus Services

This Amendment for Contract Services ("Amendment 17") to the Agreement covers
AT&T Frame Relay Plus Implementation and Management Services ("Services") that
NetSolve shall provide to AT&T in support of AT&T's Frame Relay Plus Service
offering, as requested by AT&T and as described herein. This Amendment 17 is an
integral part of the Agreement and shall be governed by the terms of the
Agreement. In the event of any conflict between the terms of this Amendment 17
and the terms of the Agreement, the terms of this Amendment 17 shall prevail
with respect to the Services provided under this Amendment.

For purposes of this Amendment 17 only, the following Paragraphs in the
Agreement are deleted in their entirety and replaced with the Paragraphs below:

Paragraph 1 - Statement of Work

NetSolve shall provide Services to AT&T in support of AT&T's Frame Relay Plus
Service offering in accordance with the "Statement of Work," Attachments K-1,
K-2, K-3, and K-4 attached to Amendment Number 7 to the Agreement.
Notwithstanding the preceding sentence, the Order Management portions of these
attachments are deleted in their entirety. Services shall be available to AT&T
worldwide. Modifications to this Statement of Work and its requirements as set
forth in Attachments K-1, K-2, K-3, and K-4 may be requested from time to time
by AT&T. The pricing contained herein shall apply to Services requested or any
modification, provided that the modifications requested do not require the
furnishing of more material or labor by NetSolve or longer times for performance
of services. NetSolve shall immediately notify AT&T's Contract Representative,
in writing, of any requested modification which NetSolve reasonably believes
will require an increase to the prices contained in Paragraph 4 - Payment for
Services, and shall furnish the amount of such proposed increase in such writing
with appropriate supporting documentation substantiating the basis for the
requested price increase. Following delivery of such notice, NetSolve shall not
proceed with Services with any such modification until AT&T and NetSolve
Contract Representatives (as then designated and authorized) agree, in writing,
to the appropriate charges.

"Orders" for Services pursuant to this Amendment 17 shall be sent to NetSolve
via a mutually agreed upon method with the current practice of providing
NetSolve copies of the AT&T order documents with the End User being deemed
approved by both parties for all Orders to date and for future Orders unless a
new method is approved in writing by both parties. For purposes of this
Amendment 17, "AT&T End User Customer" or "End user customer" means an AT&T end
user customer to which NetSolve is providing Services pursuant to this Amendment
17. Monthly recurring Service charges as further described in Paragraph 4 shall
commence on the start date of Services as requested by AT&T (such date is herein
defined as the "CRD") and continue for the number of months specified on the
current End User contract between AT&T and AT&T's End User (up to a maximum of
36 months) (the "Service Term") except that to the extent AT&T continues the
Services to the End User beyond the Service Term on a month-month basis then
NetSolve may, at AT&T's option, provide the Services until cancellation by AT&T
with thirty (30) days notice to NetSolve. Renewals or extensions of end user
contracts between AT&T and AT&T End Users are not defined herein as Service Term
or End User Service Term and Services under such renewals and extensions may
only be given to NetSolve under this Amendment 17 in AT&T's sole discretion and
with AT&T's express written consent. AT&T may, at its option, keep End Users
with NetSolve under this Amendment 17 after expiration of such End Users'
Service Terms on a month-to-month basis until the earlier of cancellation by
AT&T with thirty (30) days notice to NetSolve or December 31, 2007. The
agreement term for ordering Frame Relay Plus Service is set forth in Paragraph 3
("Ordering Term").

Upon expiration or termination of this Amendment 17, all Services will continue
to be provided through the end of each End User Service Term and will be
non-cancelable by either party except as set forth herein in Paragraph 24 of
this Amendment 17.

The Recurring Services pricing in this Amendment 17 will continue to apply to
all new end user customers from December 31, 2000 until expiration or
termination of this Amendment. Customers for which NetSolve received an order
from AT&T on or before December 31, 2000 which is currently being billed at less
than $* shall increase to $* as of the Effective Date. This Recurring Services
pricing will remain effective provided the ratio of unmanaged PVCs to managed
PVCs does not exceed 1.2 to 1. In the event that such ratio exceeds 1.2 to 1,
the parties shall negotiate reasonable pricing modifications to the Recurring
Services pricing herein. The above pricing shall apply to AT&T IPFR Sites
installed until July 31, 2002.

In the event the following operating results are achieved, NetSolve will
negotiate in good faith to reduce the above pricing under this Amendment 17 for
recurring services. Any lower price which NetSolve and AT&T agree to will apply
to all new orders entered into after the effective date of the price decrease.

o    The mean-time-to-repair, as reported from NetSolve's Trouble Ticket system
     (and which is currently utilized for the monthly performance reporting to
     AT&T by NetSolve), is 3.0 hours or less for three consecutive months; and

o    The ratio of the total number of Trouble Tickets to the total number of
     devices managed is less than or equal to one Trouble Ticket per four
     devices managed over the same period as the previous bullet point.

information contained in NetSolve's database in a format to be mutually agreed
upon, thirty (30) minutes of project management assistance per site (including
any time required for turn-up of management PVC) (collectively Transition
Services"). Any time in excess of thirty (30) minutes per site on a per-customer
basis will be billed at $* per hour (in half-hour increments). See Exhibit 2.
This charge will not apply to Sites which are migrated to a non-NetSolve
operations center that do not require Transition Services and Sites cancelled or
terminated under Paragraph 24-1) for NetSolve's default; 24-2)a) (unless due to
AT&T's default of its payment obligations); 24-2)b); 24-3)(a)(1) and (2); and
24-3(a)(4) as long as no Transition Services are required.

The above pricing for Nonrecurring Services will be fixed for the Term of this
Agreement as set forth in Paragraph 3.

NetSolve will maintain capacity to install up to * Sites per quarter as long as
the Minimum New Site Installation Percentage is at or above 90%; if the Minimum
New Site Installation Percentage falls below 90% in any quarter, then NetSolve
will maintain capacity to install 120% of the Site installations performed by
NetSolve in the immediately preceding quarter. In return, AT&T agrees to order
for installation the minimum new site percentage throughout the periods set
forth in the following table ("Minimum New Site Installation Percentage"). The
Minimum New Site Installation Percentage shall be calculated as a percentage of
the total new AT&T Frame Plus Sites to be installed by AT&T over the time
periods set forth less any Site that NetSolve is unable to install in strict
conformance with the installation schedule per the applicable End User contract.
This minimum will include all installations of Sites under (i) this Amendment
17 and Amendment 14 plus (ii) Amendment Number 15 (AT&T ATM Plus) plus (iii)
Amendment No. X (AT&T ATM Plus Service utilizing ADC Kentrox Platform). This
minimum will further include installations for Sites for AT&T IPFR. In the event

Installation Percentage or does not increase the Minimum New Site Installation
Percentage in an amount equal to the Shortfall in the period following such a
failure to meet the applicable target Minimum New Site Installation Percentage,
AT&T shall pay NetSolve an amount equal to the Recurring Service fees that AT&T

Paragraph 6 - COMPETITION

Paragraph 6 of the Agreement as amended by Amendment 5 is replaced by the
following for this Amendment 17 only:

Paragraph 6- COMPETITION

A. NetSolve shall not, without prior written authorization by AT&T's Contract
Representative for this Amendment 17, directly contract with any AT&T End User
Customer to provide substantially the same Services hereunder (i.e., management
of only a Visual Networks DSU and the associated Visual Networks PAM) during the
Term of this Amendment 17 and for a period of ninety (90) days thereafter. If
NetSolve breaches or violates the preceding sentence on more than one occasion,
AT&T may, in its sole discretion, immediately reduce the Minimum New Site
Installation Percentage by notifying NetSolve in writing that AT&T has elected
to make such reduction and upon receipt of such notice, NetSolve will install
any pending Orders in accordance with the schedule for such Orders but shall not
be obligated to maintain any additional installation capacity beyond such
pending Orders. All Orders received by NetSolve prior to the date of AT&T's
notice shall remain in place for the remainder of the Service Term unless
otherwise cancelable under Paragraph 24. NetSolve may, however, subcontract with
an independent third party to provide substantially the same Services to an AT&T
End User Customer up to a maximum total removal from AT&T of 2750 End User
Customer Sites (including any Sites obtained by NetSolve as a result of
NetSolve's above obligation to refrain from directly contracting with AT&T End
Users) if the specific End User Customer opportunity was not developed as a
result of performing Services hereunder and did not involve any Solicitation by
NetSolve. Upon removal of more than 2750 Sites, AT&T shall have the right to
immediately reduce the Minimum Site Installation percentage to zero. For
purposes of this Paragraph 6 of Amendment 17, "AT&T End User Customer" means an
end user customer to which NetSolve is providing Services pursuant to this
Amendment 17.

In addition, NetSolve agrees that with respect to the Services provided by
NetSolve under this Amendment 17 that it will not directly contact any End User
Customer or perform any activity with any End User Customer that is not
reasonably necessary in order for NetSolve to perform its responsibilities as
specifically set forth in the Agreement or this Amendment 17, including without
limitation, marketing activities, customer surveys, forums or meetings without
the specific prior written authorization of AT&T's Contract Representative as
set forth in Paragraph 2. In the event that an AT&T End

User Customer contacts NetSolve with respect to the Services for a purpose that
is not reasonably necessary in order for NetSolve to perform its
responsibilities as specifically set forth in the Agreement or this Amendment
17, NetSolve shall inform such AT&T End User Customer that such contact is not
permitted and shall terminate the contact and report immediately such contact to
AT&T's Contract Representative as set forth in Paragraph 2. NetSolve shall
represent itself to any End User Customer hereunder as a representative of AT&T.

NetSolve acknowledges and agrees that all customer information derived as a
result of performing Services hereunder is the property of AT&T. NetSolve shall
promptly return all such customer information to AT&T upon termination or
expiration of this Amendment or the transfer of the applicable AT&T End User
Customer from NetSolve whichever is earlier with the exception of (i) Orders and
other business records which NetSolve must retain to support its financial and
tax reporting obligations and customary corporate record-keeping requirements;
and (ii) data contained electronically in NetSolve's databases which NetSolve
will purge in accordance with its standard practices. The applicable data in
item (ii) will be provided to AT&T for the Transition Fee specified in Paragraph
4. In perpetuity, NetSolve shall not: (1) use any customer information that it
obtains as a result of performing the Services hereunder or the network designs
developed hereunder to compete with AT&T or others; and (2) NetSolve should not
disclose such customer information or network designs to any third party,
employees, agents, subcontractors or suppliers for the purpose of competing with
AT&T or others. Such disclosure shall not be prohibited: (i) if NetSolve is
required in a judicial, administrative or governmental proceeding to disclose
any such information, however, NetSolve shall provide AT&T with prompt notice of
such a requirement so AT&T may seek an appropriate protective order; or (ii) in
connection with a federal or state securities filing, or in any effort to raise
capital or borrow funds from any public or private source provided NetSolve
shall provide AT&T with prompt notice of any disclosure (for example, in
connection with a road show regarding a pending public offering of securities,
NetSolve would inform AT&T in advance of the types of information NetSolve
proposes to disclose such as length and estimated value of any contract or
amendment thereto with AT&T). AT&T may seek an appropriate protective order if
the parties do not reach agreement about the scope and content of any proposed
disclosure.

          ii)  if NetSolve evidences an inability to pay debts as they become

               Amendment 17, and any or all Orders may be immediately terminated
               by AT&T; or

3)   Termination of Individual Orders placed pursuant to this Amendment 17.

     a)   AT&T may terminate an Order, without charge, upon 30 days written
          notice if 1) AT&T's End User is dissatisfied, in such End User's sole
          discretion, with the Services performed by NetSolve; 2) AT&T's End
          User has a change in its normal course of business that impacts
          Services, such as relocation to a location not utilizing Frame Relay
          Plus Services, office closings or any business condition or downturn
          resulting in removal of Sites from AT&T Frame Plus by the AT&T End
          User; 3) the End User's Contract expires or is terminated for any
          reason; 4) the End User downgrades to a non-managed service; or 5) the

          terminations where under Paragraph 24-3)a)5), and End User purchases
          another AT&T managed service resulting in cancellation of AT&T Frame
          Plus service hereunder in the first twelve months of such End User's
          Service Term, AT&T shall pay NetSolve a termination fee equal to the
          Recurring Service charge that would have been payable from AT&T to
          NetSolve for the terminated Sites from the date of cancellation to the
          end of first twelve months of the End User's Service Term. If an End
          User cancels AT&T Frame Plus services any time after the first 12
          months of the applicable Service Term, there shall be no termination
          fee payable to NetSolve for such Sites.

     b)   AT&T may terminate upon thirty (30) days written notice by AT&T, at no
          charge, all Orders upon expiration of the Service Term between AT&T
          and NetSolve.

     c)   AT&T may terminate upon thirty (30) days written notice by AT&T, at no
          charge, any Order that includes modifications (as described in
          Paragraph 1 of this Amendment 17), in the event AT&T and NetSolve are
          unable to agree on pricing for any modifications to the Statement Of
          Work. Modifications cannot apply retroactively to installed business
          unless AT&T and NetSolve mutually agree.

     contained within the Original Contract under Paragraph 6, Competition or
     the Agreement, NetSolve agrees and acknowledges that all customer data
     {e.g. (without limitation): the customer premises equipment configurations,

     and will be promptly conveyed and returned to AT&T in electronic format
     upon written notice.

                                      ----

SLAs include the performance of NetSolve and any third party suppliers of
NetSolve for which NetSolve has management responsibilities under Amendment 17
to Amendment Number 17. SLAs shall not include a failure resulting from any act,
omission or failure of AT&T or its affiliates, service supplier, or End User
customer. In the event any act, omission, or failure of AT&T or the End User can
be reasonably managed by NetSolve to increase the SLA performance, NetSolve will
attempt to work with that entity to increase the SLA performance if such work
does not, in NetSolve's sole opinion, significantly increase NetSolve's costs.

         (1) Failure to achieve these SLAs (after deletion of failures resulting
         from any act, omission or failure of AT&T or its affiliates, service
         supplier, or End User customer) shall not be considered a default under
         Paragraph 24 unless those SLAs marked with an "*" are fifteen
         percentage points below the stated SLA for two consecutive months and
         AT&T notifies NetSolve it is in default within ten (10) days after
         receipt of the applicable SLA report.

                            Exhibit 2 to Amendment 17

              Process for transitioning End Users to another center

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

AT&T must submit all transition requests via the MACD process and must state the
reason for transition on the request. An AT&T single-point-of-contact (SPOC)
must be included on the request. Once the approved MACD is received at NetSolve
a CSO will be created with a de-install line item. A precise date and time
should be scheduled with NetSolve by AT&T for this activity.

Upon receipt of a complete MACD, the following actions will be taken:

     o    NetSolve will un-manage the End User customer sites based on the
          requested MACD date (take the sites off of the poller).

     o    NetSolve will send the AT&T SPOC the current End User customer
          information from our records in a spreadsheet format.

     o    NetSolve will participate in the scheduling of the de-install with the
          End User customer and the AT&T SPOC.

     o    AT&T will notify NetSolve via email when the management and PAC (Level
          3) PVC have been disconnected.

     o    Upon receipt of the confirmation email, NetSolve will coordinate 1)
          deletion of customer information off of PAM and 2) disconnecting IPs,
          virtual circuits and devices in NetSolve's tools.

Any work in addition to that above, or any additional work required due to
delays, changes, or failure of AT&T or the End User customer to perform their
obligations, will be billed at $* per hour (in half-hour increments).
