the Indenture as a single class or series of Securities.

         Section 202 Limitation on Aggregate Principal Amount. The Trustee
shall authenticate and deliver Series A Notes for original issue on the Issue
Date in the aggregate principal amount of $200,000,000 and Series B Notes from

         (a) The Notes shall bear interest at a rate of 7.25% per year, from
and including September 9, 2003 (the "Issue Date") to, but excluding, the Notes
Maturity Date. Such interest shall be payable semiannually in arrears on March
1 and September 1 of each year (each an "Interest Payment Date"), beginning
March 1, 2004 to the persons in whose names the Notes are registered at the
close of business on February 15 and August 15 (each a "Regular Record Date")
(whether or not a Business Day), as the case may be, immediately preceding such
Interest Payment Date.

         (b) Any such interest not so punctually paid or duly provided for
shall forthwith cease to be payable to the Holder on such Regular Record Date
and shall either (i) be paid to the Person in whose name such Note (or one or
more Predecessor Securities) is registered at the close of business on the
Special Record Date for the payment of such Defaulted Interest to be fixed by
the Trustee, notice whereof shall be given to Holders of the Notes not less
than 10 days prior to such Special Record Date, or (ii) be paid at any time in
any other lawful manner not inconsistent with the requirements of any
securities exchange or automated quotation system on which the Notes may be
listed or traded, and upon such notice as may be required by such exchange or
automated quotation system, all as more fully provided in the Indenture.

         (c) The amount of interest payable for any period shall be computed on
the basis of a 360-day year of twelve 30-day months. The amount of interest
payable for any partial period shall be computed on the basis of a 360-day year
of twelve 30-day months and the days elapsed in any partial month. In the event
that any date on which interest is payable on a Note is not a

                                       6
<PAGE>
Business Day, then a payment of the interest payable on such date will be made
on the next succeeding day which is a Business Day (and without any interest or
other payment in respect of any such delay) with the same force and effect as
if made on the date the payment was originally payable.

         (d) Any principal and premium, if any, and any installment of
interest, which is overdue shall bear interest at the rate of 7.25% per annum
(to the extent permitted by law), from the dates such amounts are due until
they are paid or made available for payment, and such interest shall be payable
on demand.

         (e) The interest rate borne by the Registrable Securities will be
increased by .25% per annum upon the occurrence of each Registration Default,
which rate will increase by an additional .25% per annum if such Registration
Default has not been cured within 90 days after the occurrence thereof and will
continue until all Registration Defaults have been cured ("Additional
Interest"); provided that the aggregate amount of any such increase in the
interest rate on the Registrable Securities shall in no event exceed .50% per
annum; provided, further, that if the Exchange Offer Registration Statement is
not declared effective on or prior to the 270th calendar day following the
Issue Date and the Company shall request Holders of Registrable Securities to
provide the information called for by the Registration Rights Agreement for
inclusion in the Shelf Registration Statement, the Registrable Securities owned
by Holders who do not deliver such information to the Company or who do not
provide comments to the Company on the Shelf Registration Statement when
required pursuant to the Registration Rights Agreement shall not be entitled to
any such Additional Interest for any day after the 315th calendar day following
the Issue Date. All accrued Additional Interest shall be paid to Holders of
Registrable Securities in the same manner and at the same time as regular
payments of interest on the Registrable Securities. Following the cure of all
Registration Defaults, the accrual of Additional Interest shall cease and the
interest rate on the Registrable Securities will revert to 7.25% per annum.

         Section 205 Paying Agent; Place of Payment. The Trustee shall
initially serve as the Paying Agent for the Notes. The Company may appoint and
change any Paying Agent or approve a change in the office through which any
Paying Agent acts without notice, other than notice to the Trustee. The Company
or any of its Subsidiaries or any of their Affiliates may act as Paying Agent.
The Place of Payment where the Notes may be presented or surrendered for
payment shall be the Corporate Trust Office of the Trustee. At the option of
the Company, payment of interest may be made (i) by check mailed to the address
of the Person entitled thereto as such address shall appear in the Security
Register or (ii) by wire transfer in immediately available funds at such place
and to such account as may be designated in writing by the Person entitled
thereto as specified in the Security Register.

         Section 206 Place of Registration or Exchange; Notices and Demands
With Respect to the Notes. The place where the Holders of the Notes may present
the Notes for registration of transfer or exchange and may make notices and
demands to or upon the Company in respect of the Notes shall be the Corporate
Trust Office of the Trustee.

initially issued at 99.782% of their principal amount plus accrued interest, if
any, from September 9, 2003.

                                  ARTICLE IV

                        Optional Redemption of the Notes

         Section 401 Redemption Price.

         (a) The Company shall have the right to redeem the Notes, in whole or
in part, at its option at any time from time to time at a price equal to (i)
100% of the principal amount thereof plus (ii) accrued and unpaid interest
thereon, if any, including Additional Interest, if any, to but excluding the
Redemption Date plus (iii) the Make-Whole Premium, if any (collectively, the
"Redemption Price").

         (b) The amount of the Make-Whole Premium with respect to any Note (or
portion thereof) to be redeemed will be equal to the excess, if any, of: (i)
the sum of the present values, calculated as of the Redemption Date, of: (A)
each interest payment that, but for such redemption, would have been payable on
the Note (or portion thereof) being redeemed on each Interest Payment Date
occurring after the Redemption Date (excluding any accrued and unpaid interest
for the period prior to the Redemption Date); and (B) the principal amount
that, but for such redemption, would have been payable on the Note (or portion
thereof) being redeemed at the Notes Maturity Date; over (ii) the principal
amount of the Note (or portion thereof) being redeemed. The present values of
interest and principal payments referred to in clause (i) above will be
determined in accordance with generally accepted principles of financial
analysis. Such present values will be calculated by discounting the amount of
each payment of interest or principal from the date that each such payment
would have been payable, but for the redemption, to the Redemption Date at a
discount rate equal to the Comparable Treasury Yield (as defined below) plus 50
basis points.

         (c) The Make-Whole Premium shall be calculated by an independent
investment banking institution of national standing appointed by the Company;
provided, that if the Company fails to make such appointment at least 45 days
prior to the Redemption Date, or if the institution so appointed is unwilling
or unable to make such calculation, such calculation shall be made by Deutsche
Bank Securities Inc., or, if such firm is unwilling or unable to make such
calculation, by an independent investment banking institution of national
standing appointed by the Company (in any such case, an "Independent Investment
Banker").

<PAGE>
         Section 402 Make-Whole Premium Calculation.

         (a) For purposes of determining the Make-Whole Premium, "Comparable
Treasury Yield" means a rate of interest per annum equal to the weekly average
yield to maturity of United States Treasury securities that have a constant
maturity that corresponds to the remaining term to maturity of the Notes to be
redeemed, calculated to the nearest 1/12th of a year (the "Remaining Term").
The Comparable Treasury Yield shall be determined as of the third Business Day
immediately preceding the applicable Redemption Date.

         (b) The weekly average yields of United States Treasury securities
shall be determined by reference to the most recent statistical release
published by the Federal Reserve Bank of New York and designated "H.15 (519)
Selected Interest Rates" or any successor release (the "H.15 Statistical
Release"). If the H.15 Statistical Release sets forth a weekly average yield
for United States Treasury securities having a constant maturity that is the
same as the Remaining Term, then the Comparable Treasury Yield shall be equal
to such weekly average yield. In all other cases, the Comparable Treasury Yield
shall be calculated by interpolation, on a straight-line basis, between the
weekly average yields on the United States Treasury securities that have a
constant maturity closest to and greater than the Remaining Term and the United
States Treasury securities that have a constant maturity closest to and less
than the Remaining Term (in each case as set forth in the H.15 Statistical
Release). Any weekly average yields so calculated by interpolation shall be
rounded to the nearest 1/100th of 1%, with any figure of 1/200th of 1% or above
being rounded upward. If weekly average yields for United States Treasury
securities are not available in the H.15 Statistical Release or otherwise, then
the Comparable Treasury Yield shall be calculated by interpolation of
comparable rates selected by the Independent Investment Banker.

         Section 403 Partial Redemption. If the Company redeems the Notes in
part pursuant to this Article Four, the Trustee shall select the Notes to be
redeemed on a pro rata basis or by lot or by such other method that the Trustee
in its sole discretion deems fair and appropriate. The Company shall redeem
Notes pursuant to this Article IV in multiples of $1,000 in original principal
amount. A new Note in principal amount equal to the unredeemed portion of the
original Note shall be issued upon cancellation of the original Note.

         Section 404 Notice of Optional Redemption. If the Company elects to
exercise its right to redeem all or some of the Notes pursuant to this Article
IV, the Company or the Trustee shall mail a notice of such redemption to each
Holder of a Note that is to be redeemed not less than 30 days and not more than
60 days before the Redemption Date. If any Note is to be redeemed in part only,
the notice of redemption shall state the portion of the principal amount to be
redeemed.

                                   ARTICLE V

                            Restrictions on Transfer

         Rule 144A under the Securities Act or (2) pursuant to an exemption
         from registration in accordance with Rule 144 under the Securities Act
         (and based upon an opinion of counsel if the Company or the Trustee so
         requests) or (3) pursuant to an effective registration statement under
         the Securities Act, a certification to that effect from such Holder
         (in substantially the form of Exhibit B hereto); or

                  (iii) if such Transfer Restricted Securities are being

         counsel to that effect if the Company or the Trustee so requests; or

                  (iv) if such Transfer Restricted Securities are being

         from the registration requirements of the Securities Act, a
         certification to that effect from such Holder (in substantially the
         form of Exhibit B hereto) and an opinion of counsel to that effect if
         the Company or the Trustee so requests.

         (b) Transfer and Exchange of the Notes.

         (d) Solely with respect to the Notes issued hereby, and pursuant to
Section 501(7) of the Original Indenture, the following shall each constitute
an "Event of Default" in addition to the other events set forth in Section 501
of the Original Indenture:

                  "(i) The default by the Company, CERC or CenterPoint Houston
         in a scheduled payment at maturity, upon redemption or otherwise, in
         the aggregate principal amount of $50 million or more, after the

         acceleration of any Indebtedness of the Company, CERC or CenterPoint
         Houston in such aggregate principal amount, so that it becomes due and
         payable prior to the date on which it would otherwise have become due
         and payable and such payment default is not cured or such acceleration
         is not rescinded within 30 days after notice to the Company in
         accordance with the terms of the Indebtedness; provided that such
         payment default or acceleration of CERC or CenterPoint Houston shall
         not to be an Event of Default if, at the time such event occurs, CERC
         or CenterPoint Houston, as the case may be, shall not be an Affiliate
         of the Company; and

                  (ii) The Company defaults in its obligation to redeem the

         hereof;".

         Section 602 Modification and Waiver. In addition to those matters set
forth in Section 902 of the Indenture, with respect to the Notes, no amendment

for, semi-annually on March 1 and September 1 in each year, commencing March 1,
2004, at the rate of 7.25% per annum, until the principal hereof is paid or
made available for payment, provided that any principal and premium, and any
such installment of interest, which is overdue shall bear interest at the rate
of 7.25% per annum (to the extent permitted by applicable law), from the dates
such amounts are due until they are paid or made available for payment, and
such interest shall be payable on demand. The amount of interest payable for
any period shall be computed on the basis of twelve 30-day months and a 360-day
year. The amount of interest payable for any partial period shall be computed
on the basis of a 360-day year of twelve 30-day months and the days elapsed in
any partial month. In the event that any date on which interest is payable on
this Security is not a Business Day, then a payment of the interest payable on
such date will be made on the next succeeding day which is a Business Day (and
without any interest or other payment in respect of any such delay) with the
same force and effect as if made on the date the payment was originally
payable. A "Business Day" shall mean any day other than a Saturday, a Sunday or
a day on which banking institutions in The City of New York are authorized or
required by law, regulation or executive order to close. The interest so
payable, and punctually paid or duly provided for, on any Interest Payment Date
will, as provided in such Indenture, be paid to the Person in whose name this
Security (or one or more Predecessor Securities) is registered at the close of
business on the Regular Record Date for such interest, which shall be February
15 or August 15 (whether or not a Business Day), as the case may be, next
preceding such Interest Payment Date. Any such interest not so punctually paid
or duly provided for shall forthwith cease to be payable to the Holder on such
Regular Record Date and shall either be paid to the Person in whose name this
Security (or one or more Predecessor Securities) is registered at the close of
business on a Special Record Date for the payment of such Defaulted Interest to
be fixed by the Trustee, notice whereof shall be given to Holders of Securities
of this series not less than 10 days prior to such Special Record Date, or be
paid at any time in any other lawful manner not inconsistent with the
requirements of any securities exchange or automated quotation system on which
the Securities of this series may be listed or traded, and upon such notice as
may be required by such exchange or automated quotation system, all as more
fully provided in said Indenture.

         Payment of the principal of (and premium, if any) and any such
interest on this Security will be made at the Corporate Trust Office of the
Trustee, in such coin or currency of the United States of America as at the
time of payment is legal tender for payment of public and private debts;
provided, however, that at the option of the Company payment of interest may be
made (i) by check mailed to the address of the Person entitled thereto as such
address shall appear in the Security Register or (ii) by wire transfer in
immediately available funds at such place and to such account as may be
designated in writing by the Person entitled thereto as specified in the
Security Register.

         Reference is hereby made to the further provisions of this Security
set forth on the reverse hereof, which further provisions shall for all
purposes have the same effect as if set forth at this place.

                            CENTERPOINT ENERGY, INC.

                       7.25% NOTES DUE 2010, SERIES [A/B]

         This Security is one of a duly authorized issue of securities of the
Company (herein called the "Securities"), issued and to be issued in one or
more series under an Indenture, dated as of May 19, 2003 (herein called the
"Indenture", which term shall have the meaning assigned to it in such
instrument), between the Company and JPMorgan Chase Bank, as Trustee (herein
called the "Trustee", which term includes any successor trustee under the
Indenture), to which Indenture and all indentures supplemental thereto
reference is hereby made for a statement of the respective rights, limitations
of rights, duties and immunities thereunder of the Company, the Trustee and the
Holders of the Securities and of the terms upon which the Securities are, and
are to be, authenticated and delivered. This Security is one of the series
designated on the face hereof, initially limited in aggregate principal amount
to $200,000,000; provided, however, that the authorized aggregate principal
amount of the Securities may be increased above such amount by a Board
Resolution to such effect.

         The Company shall have the right to redeem the Securities of this
series, in whole or in part, at its option at any time from time to time at a
price equal to (i) 100% of the principal amount thereof plus (ii) accrued and
unpaid interest thereon, if any, including Additional Interest, if any, to (but
excluding) the Redemption Date plus (iii) the Make-Whole Premium, if any.

         The amount of the Make-Whole Premium with respect to any Security of
this Series (or portion thereof) to be redeemed will be equal to the excess, if
any, of: (i) the sum of the present values, calculated as of the Redemption
Date, of: (A) each interest payment that, but for such redemption, would have
been payable on the Security of this series (or portion thereof) being redeemed
on each Interest Payment Date occurring after the Redemption Date (excluding
any accrued and unpaid interest for the period prior to the Redemption Date);
and (B) the principal amount that, but for such redemption, would have been
payable on the Security of this series (or portion thereof) being redeemed at
September 1, 2010; over (ii) the principal amount of the Security of this
series (or portion thereof) being redeemed. The present values of interest and
principal payments referred to in clause (i) above will be determined in
accordance with generally accepted principles of financial analysis. Such
present values will be calculated by discounting the amount of each payment of
interest or principal from the date that each such payment would have been
payable, but for the redemption, to the Redemption Date at a discount rate
equal to the Comparable Treasury Yield (as defined below) plus 50 basis points.

         For purposes of determining the Make-Whole Premium, "Comparable
Treasury Yield" means a rate of interest per annum equal to the weekly average
yield to maturity of United States Treasury securities that have a constant
maturity that corresponds to the remaining term to maturity of the Securities
of this series, calculated to the nearest 1/12th of a year (the "Remaining
Term"). The Comparable Treasury Yield shall be determined as of the third
Business Day immediately preceding the Redemption Date.

                                      A-5
<PAGE>
         The weekly average yields of United States Treasury securities shall
be determined by reference to the most recent statistical release published by
the Federal Reserve Bank of New York and designated "H.15 (519) Selected
Interest Rates" or any successor release (the "H.15 Statistical Release"). If
the H.15 Statistical Release sets forth a weekly average yield for United
States Treasury securities having a constant maturity that is the same as the
Remaining Term, then the Comparable Treasury Yield shall be equal to such
weekly average yield. In all other cases, the Comparable Treasury Yield shall
be calculated by interpolation, on a straight-line basis, between the weekly
average yields on the United States Treasury securities that have a constant
maturity closest to and greater than the Remaining Term and the United States
Treasury securities that have a constant maturity closest to and less than the
Remaining Term (in each case as set forth in the H.15 Statistical Release). Any
weekly average yields so calculated by interpolation shall be rounded to the
nearest 1/100th of 1%, with any figure of 1/200th of 1% or above being rounded
upward. If weekly average yields for United States Treasury securities are not
available in the H.15 Statistical Release or otherwise, then the Comparable
Treasury Yield shall be calculated by interpolation of comparable rates
selected by the Independent Investment Banker.

         In the event of redemption of this Security in part only, a new
Security or Securities of this series and of like tenor for the unredeemed
portion hereof will be issued in the name of the Holder hereof upon the
cancellation hereof.

         The Securities of this series are not entitled to the benefit of any
sinking fund.

         The Indenture contains provisions for satisfaction and discharge of
the entire indebtedness of this Security upon compliance by the Company with
certain conditions set forth in the Indenture.

         The Indenture contains provisions for defeasance at any time of the
entire indebtedness of this Security or certain restrictive covenants and
Events of Default with respect to this Security, in each case upon compliance
with certain conditions set forth in the Indenture.

         If an Event of Default with respect to Securities of this series shall
occur and be continuing, the principal of the Securities of this series may be
declared due and payable in the manner and with the effect provided in the
Indenture.

         The Indenture permits, with certain exceptions as therein provided,
the amendment thereof and the modification of the rights and obligations of the
Company and the rights of the Holders of the Securities of each series to be
affected under the Indenture at any time by the Company and the Trustee with
the consent of the Holders of a majority in principal amount of the Securities
at the time Outstanding of each series to be affected. The Indenture also
contains provisions permitting the Holders of specified percentages in
principal amount of the Securities of each series at the time Outstanding, on
behalf of the Holders of all Securities of such series, to waive compliance by
the Company with certain provisions of the Indenture and certain past defaults
under the Indenture and their consequences. Any such consent or waiver by the
Holder of this Security shall be conclusive and binding upon such Holder and
upon all future Holders of this Security and of any Security issued upon the
registration of transfer hereof or in exchange

                                      A-6
<PAGE>
herefor or in lieu hereof, whether or not notation of such consent or waiver is
made upon this Security.

         As provided in and subject to the provisions of the Indenture, the
Holder of this Security shall not have the right to institute any proceeding
with respect to the Indenture or for the appointment of a receiver or trustee
or for any other remedy thereunder, unless such Holder shall have previously
given the Trustee written notice of a continuing Event of Default with respect
to the Securities of this series, the Holders of not less than 25% in principal
amount of the Securities of this series at the time Outstanding shall have made
written request to the Trustee to institute proceedings in respect of such
Event of Default as Trustee and offered the Trustee reasonable indemnity, and
the Trustee shall not have received from the Holders of a majority in principal

operational details of Nortel Networks' Products. Nortel Networks reserves the

sales by End User name and address, Nortel Networks product code, quantity and

Partner shall provide Nortel Networks with the End User name, the location of
any such Hardware or Software and any applicable serial numbers. Nortel Networks
and any of Nortel Networks' suppliers shall have a right, upon reasonable
notice, to examine all such records.

support under this Agreement may be subcontracted only to Nortel Networks, other
Nortel Networks Premium Partners authorized to provide such support, or other
third parties (for example, Supplemental Service Contract Providers) as approved
by Nortel Networks in writing. Premium Partner remains responsible for all
obligations performed by its subcontractors.

9. SALES AGENT AUTHORIZATION

In its sole discretion, Nortel Networks may approve Premium Partner's use of a
sales agent(s) for the purpose of selling Products within the scope of the
Premium Partner's Product authorization ("Sales Agent"). For the Products listed

Agents shall be used by Premium Partner in accordance with the Nortel Networks
guidelines set forth in Attachment D and Premium Partner agrees to indemnify,
defend and hold Nortel Networks harmless from any claims, suits or proceedings,

10. ENGINEERING CHANGES

Premium Partner agrees to permit Nortel Networks to install any mandatory
engineering changes such as retrofits designed to correct electrical or
mechanical conditions rendering the Product functionally inoperable and
creating, in Nortel Networks' determination, a significant safety hazard ("Class
A Corrective Retrofit") on all Products in Premium Partner's inventory and to
use best efforts to enable Nortel Networks to install such engineering changes
on Premium Partner's End Users' Products. Class A Corrective Retrofits shall be
installed at Nortel Networks' expense and any removed property shall become
Nortel Networks' property. Alternatively, Nortel Networks may provide Premium
Partner, either directly or through Nortel Networks Stocking Distributors, with
the parts (at no charge) and instructions to do the installation and reimburse
Premium Partner for labor as specified and agreed. Nortel Networks may make
available to Premium Partner other engineering changes ("Class B Corrective
Retrofits") on such terms as may be specified by Nortel Networks.

11. SOFTWARE LICENSES

Nortel Networks grants Premium Partner a limited, nonexclusive, nontransferable
license to use the Software internally and Distribute the Software in the
Territory in accordance with the terms of this Agreement and the Nortel Networks
Software License as set forth in Attachment B ("Nortel Networks Software
License"). Software may be licensed for use only with designated Products
Distributed by Premium Partner or other specified equipment and the right to use
the Software may be limited to a specified activation or usage level. For
Software requiring an executed license, Premium Partner agrees to obtain a
signed Nortel Networks Software License as set forth in Attachment B before such
Software is provided to the End User. With respect to Third Party Software and
Software licensed under any Nortel Networks or third party "shrink wrap" or
"click" licenses, Premium Partner agrees that such licenses shall govern the use
of such Software and Premium Partner shall obtain agreement that End Users
comply with such licenses. Upon termination of this Agreement for any reason,
Premium Partner's right to Distribute the Software shall terminate, and Premium
Partner agrees to return all remaining Software in its inventory to Nortel
Networks. Nortel Networks expressly reserves the right to modify its license
agreements, and any modification shall apply to all Software transactions
occurring after the effective date of any such modification.

12. LIMITED WARRANTY AND SUPPORT

For Products purchased directly from Nortel Networks, Nortel Networks provides a
limited warranty as set forth in the Nortel Networks Direct Purchase Supplement.
Products purchased by Premium Partner from Nortel Networks Stocking Distributors
are warranted through Nortel Networks Stocking Distributors, who are responsible
for managing and resolving any Premium Partner warranty claims.

Life Cycle Support shall be provided as described in the Product Catalog. Nortel
Networks will not modify Life Cycle Support for any given Product more than once
annually and without at least 90 day advance notice during the Term.

13. CONFIDENTIAL INFORMATION

a)   Confidential Information ("Information") means i) Software, Third Party
     Software and any information identified as confidential at the time of
     disclosure or information which the receiving party knows or has reason to
     know is confidential, e.g. Product pricing and discounts; and ii) all
     business, technical, marketing and financial information and data that is
     clearly marked with a restrictive legend of the disclosing party
     ("Discloser"), including but not limited to, sales leads, customer prospect
     information, business plans or market intelligence provided by Nortel
     Networks.

b)   The party receiving Information ("Recipient") will use the same care and
     discretion, but not less than reasonable care, to avoid disclosure,
     publication or dissemination of Information as it uses with its own similar
     information that it does not wish to disclose, publish or disseminate. The
     Recipient may disclose Information only to i) its employees and employees
     of its parent, subsidiary or affiliated companies and subcontractors who
     have a need to know for purposes of carrying out this Agreement; and ii)
     any other party with the Discloser's prior written consent. Before
     disclosure to any of the above parties, the Recipient will have a written
     agreement with such party sufficient to require that party to treat
     Information in accordance with this Agreement.

c)   The Recipient may disclose Information to the extent required by law.
     However, the Recipient must give the Discloser prompt notice and make a
     reasonable effort to obtain a protective order.

d)   No obligation of confidentiality applies to any Information that the
     Recipient i) already possesses without obligation of confidentiality; ii)
     develops independently; or iii) rightfully receives without obligations of
     confidentiality from a third party. No obligation of confidentiality
     applies to any Information that is, or becomes, publicly available without
     breach of this Agreement.

e)   With the exception of Software and Third Party Software, Information
     continues to be subject to this Agreement for five (5) years following the
     earlier of the termination or expiration of this Agreement.

14. LIMITATION OF LIABILITY

In no event shall Nortel Networks or its agents or suppliers be liable to
Premium Partner for more than the amount of any actual direct damages up to the
greater of U.S. $100,000 (or equivalent in local currency) or the charges for
the Products or Services that are the subject of the claim, regardless of the
cause and whether arising in contract, tort (including negligence) or otherwise.
This limitation will not apply to a) claims for damages for bodily injury
(including death) and damage to real property and

                            CONFIDENTIAL INFORMATION                 Page 4 of 7
<PAGE>
tangible personal property for which Nortel Networks is legally liable and b)
payments as set forth in Section 15 Patents and Copyrights. IN NO EVENT SHALL
NORTEL NETWORKS OR ITS AGENTS OR SUPPLIERS BE LIABLE FOR ANY OF THE FOLLOWING:
a) DAMAGES BASED ON ANY THIRD PARTY CLAIM EXCEPT AS EXPRESSLY PROVIDED HEREIN
AND IN SECTION 15; b) LOSS OF, OR DAMAGE TO, PREMIUM PARTNER'S OR PREMIUM
PARTNER'S END USERS' RECORDS, FILES OR DATA; OR c) INDIRECT, SPECIAL,
INCIDENTAL, PUNITIVE, OR CONSEQUENTIAL DAMAGES (INCLUDING LOST PROFITS OR
SAVINGS), EVEN IF NORTEL NETWORKS IS INFORMED OF THEIR POSSIBILITY.

In addition to damages for which Premium Partner is liable under the law and the
terms of this Agreement, Premium Partner agrees to indemnify Nortel Networks for
claims made against Nortel Networks by others (particularly regarding
statements, representations and warranties not authorized by Nortel Networks, or
Premium Partner's use of third party trademarks) arising out of Premium
Partner's conduct in connection with this Agreement.

15. PATENTS AND COPYRIGHTS

If a third party claims that Nortel Networks Hardware or Software purchased by
Premium Partner, either directly from Nortel Networks or from Nortel Networks
Stocking Distributors, infringes upon that party's patent or copyright, Nortel
Networks will defend Premium Partner against that claim at Nortel Networks'
expense and pay all costs and damages that a court finally awards or are agreed
upon in settlement, provided that Premium Partner a) promptly notifies Nortel
Networks in writing of the claim and b) allows Nortel Networks to control, and
cooperates with Nortel Networks in the defense and any related settlement
negotiations. If such a claim is made or appears likely to be made, Nortel
Networks agrees to secure the right for Premium Partner or Premium Partner's End
User to continue to use the Hardware or Software, or to modify it, or to replace
it with one that is equivalent. If Nortel Networks determines that none of these
alternatives is reasonably available, Premium Partner agrees to return the
Hardware or Software and/or require that Premium Partner's End User return the
Hardware and Software to Nortel Networks on Nortel Networks' written request.
Nortel Networks will then give Premium Partner a credit equal to Premium
Partner's or Premium Partner's End User's net book value as determined by
generally-accepted accounting principles for the Hardware or Software. Any such
claims against Premium Partner or liability for infringement arising from use of
the Hardware or Software following a request for return by Nortel Networks are
the sole responsibility of Premium Partner. This represents Nortel Networks'
entire obligation to Premium Partner regarding any claim of infringement. Nortel
Networks has no obligation regarding any claim based on any of the following: a)
anything Premium Partner provides which is incorporated into the Hardware or
Software; b) functionality provided by Nortel Networks at the instruction of
Premium Partner; c) the amount of revenues or profits earned or other value
obtained by the use of the Hardware or Software by Premium Partner or End User;
d) the lost revenues or profits of third parties arising from Premium Partner's
or End User's use of the Hardware or Software; e) Premium Partner's or End
User's modification of Hardware or Software; f) the combination, operation, or
use of Hardware or Software with other products not provided by Nortel Networks
as a system, or the combination, operation, or use of Hardware or Software with
any product, data, or apparatus that Nortel Networks did not provide; or g)
Premium Partner's failure to install or have installed changes, revisions,
updates as instructed by Nortel Networks; or h) infringement by a Third Party
Vendor Item alone, as opposed to its combination with Products Nortel Networks
provides to Premium Partner as a system.

16. TERMINATION

Regardless of the Term in effect, Nortel Networks or Premium Partner may
terminate this Agreement, without cause, on 60 days written notice or such
longer period as required under applicable law. If either party breaches a
material term of this Agreement, the other party may terminate the Agreement on
written notice. Examples of such material breach by Premium Partner include
failure to meet any accreditation and training requirements; failure to comply
with Premium Partner's obligations regarding Software as set forth in this
Agreement; resale, installation and maintenance of Products outside Premium
Partner's approved Territory; repudiation of this Agreement by Premium Partner;
or if Premium Partner makes material misrepresentations to Nortel Networks.
Premium Partner agrees that Nortel Networks' sole obligation is to provide the
notice set forth in this Section 16 and Nortel Networks is not liable for any
claims or losses in the event notice is provided. Prior to any such termination,
Nortel Networks may, at its discretion, provide Premium Partner a reasonable
opportunity to correct such breach. If Premium Partner fails to correct such
breach within such time period, the Agreement will terminate on the date
specified in the notice.

In addition, Nortel Networks may terminate this Agreement for material breach in
the event Premium Partner becomes insolvent or makes a general assignment for
the benefit of creditors; is unable to pay its debts as they come due; transfers
or assigns or attempts to transfer or assign any of its rights under this
Agreement other than as expressly permitted; offers or provides any inducements
in violation of law or Nortel Networks' policies in connection with this
Agreement; or experiences a change of control, which, for the purposes of this
provision, shall be defined as the legal, beneficial or equitable ownership,
directly or indirectly, of fifty percent (50%) or more of the capital stock (or
other ownership interest if not a corporation) of such entity ordinarily having
voting rights or the management control over Premium Partner.

                            CONFIDENTIAL INFORMATION                 Page 5 of 7
<PAGE>
Upon termination or expiration of this Agreement, all rights and licenses to
Distribute Products and to use Trademarks shall cease and Nortel Networks is
under no obligation to purchase any remaining Premium Partner inventory. In the
event of termination for material breach, Nortel Networks is under no obligation
to provide to Premium Partner any post termination support. At Nortel Networks'
sole discretion, upon termination Premium Partner agrees to pay for or return
any Products for which payment has not yet been made in full and/or permit
Nortel Networks to acquire any Products that are in Premium Partner's possession
at the net price paid, less any applicable credits. Any Products agreed to be
returned must be unopened and undamaged and in Premium Partner's inventory on
the date of termination. Nortel Networks reserves the right to reject any such
Products and Premium Partner agrees to pay all applicable shipping charges. If
Nortel Networks agrees to permit Premium Partner to continue certain activities
after this Agreement ends, Premium Partner agrees to do so under the terms of
this Agreement. At the end of this Agreement, both parties agree to promptly
settle any accounts and Nortel Networks reserves the right to setoff amounts
otherwise due Nortel Networks under this Agreement.
