     NEXTEL COMMUNICATIONS, INC., a corporation duly organized and existing under the laws of the
State of Delaware (herein called the “Company”, which term includes any successor Person under the
Indenture hereinafter referred to), for value received, hereby promises to pay to CEDE & Co., or
registered assigns, the principal sum of
($               )                     
on March 15, 2014, and to pay interest thereon from March 15, 2005, or from the most recent
Interest Payment Date to which interest has been paid or duly provided for, semiannually in arrears
on September 15 and March 15 in each year, commencing September 15, 2005, at the rate of 5.95% 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 that is overdue shall bear interest at the rate of
5.95% per annum (to the extent that the payment of such interest shall be legally enforceable) from
the dates such amounts are due until they are paid or made available for payment, and such interest
shall be payable on demand. Interest shall be computed on the basis of a 360-day year of twelve
30-day months. The interest so payable, and punctually paid or duly provided for, on any Interest
Payment Date will, as provided in the Indenture (as hereinafter defined) 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 the September 1 or March 1

such interest not so punctually paid or duly provided for will forthwith cease to be payable to the
Holder on such Regular Record Date and may 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 (as defined herein),
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 on which the Securities of this series may be
listed, and upon such notice as may be required by such exchange, all as more fully provided in the
Indenture.

     In the case of a default in payment of principal upon acceleration, redemption or repurchase,
the overdue principal and any overdue premium shall bear interest at the rate of 5.95% per annum
(to the extent that the payment of such interest shall be legally enforceable), from the dates such
amounts are due until they are paid or duly provided for. Interest on any overdue principal or
premium shall be payable on demand. Any such interest on overdue principal or premium which is not
paid on demand shall bear interest at the rate of 5.95% per annum (to the extent that the payment
of such interest on interest shall be legally enforceable), from the date of such demand until the
amount so demanded is paid or duly provided for, and such shall be payable on demand.

Payment of the principal of (and premium, if any) and any such interest on this Security will be
made at the office or agency of the Company maintained for that purpose in the Borough of
Manhattan, The City of New York, 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 by check mailed to the address of the
Person entitled thereto as such address shall appear in the Security Register.
Reference is hereby made to the further provisions of this Security set forth herein and in the
Indenture, which further provisions shall for all purposes have the same effect as if set forth at

     This Security is one of a duly authorized issue of securities of the Company, issued and to be
issued in one or more series (the securities of all such series herein collectively referred to as
the “Securities”) under an Indenture, dated July 31, 2003, between the Company and BNY Midwest
Trust Company, as Trustee (herein called the “Trustee”, which term includes any successor trustee
under the Indenture), as amended by the First Supplemental Indenture dated as of August 8, 2005,
between the Company and the Trustee and the Second Supplemental Indenture dated as of August 8,
2005, between the Company and the Trustee (as so amended, 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. The
Securities are unsecured general obligations of the Company.

     The Securities of this series are subject to redemption upon not less than 10 days’ notice
mailed by first class mail to each holder’s last address as it appears in the Security Register, at
any time on or after March 15, 2009, as a whole or in part, at the election of the Company, at the
following Redemption Prices (expressed as percentages of the principal amount) set forth below,
plus an amount in cash equal to all accrued and unpaid interest, if any, to the Redemption Date, if

	2011
	 	 	101.744	%

     Interest installments whose Stated Maturity is on or prior to such Redemption Date will be
payable to the Holders of such Securities, or one or more Predecessor Securities, of record at the
close of business on the relevant Record Dates referred to on the face hereof, all as provided in
the Indenture.

     In addition to any redemption provided for in the immediately preceding paragraphs, in the
event of a sale by the Company after the Closing Date and on or prior to March 15, 2007 of its
Capital Stock, other than Redeemable Stock, the Company may, at its option, within 180 days of such
sale, upon not less than 10 nor more than 60 days’ notice by mail, redeem up to 35% of the
aggregate principal amount of the Securities of this series from the net proceeds of such sale (but
only to the extent such proceeds consist of cash or readily marketable cash equivalents received in
respect of the Company’s Capital Stock so sold, in each case net of all commissions, discounts,
fees, expenses and taxes incurred in respect thereof) at a Redemption Price equal to 105.950% of
the principal amount of the Securities of this series to be redeemed plus accrued and unpaid
interest to the Redemption Date.

     The Securities of this series do not have the benefit of any sinking fund obligation.

     The Indenture provides that, subject to certain conditions, if a Change of Control occurs, the
Company shall be required to make an Offer to Purchase for all of the Securities.

     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 Indenture contains provisions for defeasance at any time of (a) the entire indebtedness
evidenced by this Security and (b) certain restrictive covenants and Events of Default with respect
to this Security, in each case upon compliance by the Company with certain conditions set forth in
the Indenture, which provisions apply to this Security.

 

 

     The Indenture also contains provisions for the elimination of certain restrictive covenants
from and after the time that both (a) this Security is first rated Investment Grade, and (b) no
Default or Event of Default exists with respect to this Security.

     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. “Event of Default” means any one of the
events specified at clauses (1) through (10) of Section 501 of 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 after having received the Required Consent (defined as follows). The Indenture also
contains provisions permitting those Persons giving the Required Consent, 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 herefor or in lieu hereof, whether or not notation of such consent or waiver is made
upon this Security.

     As used herein, “Required Consent” means, except as otherwise expressly provided in the
Indenture with respect to matters requiring the consent of each holder of any series of the
Securities affected thereby: (1) the consent of holders of not less than a majority in aggregate
principal amount at Stated Maturity of this series of Securities for any action to (a) direct the
time, method and place of conducting any proceeding for any remedy available to the Trustee, or
exercising any power conferred upon such Trustee, or (b) consent to or waive, on behalf of the
holders of all the Securities of this series, any past default and its consequences; and (2) with
respect to all other actions requiring the consent of holders of this series of the Securities, the
consent of either (a) a majority in aggregate principal amount at Stated Maturity of this series of
the Securities or (b) a majority in aggregate principal amount at Stated Maturity of (i) this
series of the Securities, (ii) the September Notes, if the holders of the September Notes are being
requested to consent to such action with respect to the terms of the September Notes or the
September Indenture, (iii) the October Notes, if the holders of the October Notes are being
requested to consent to such action with respect to the terms of the October Notes or the October
Indenture, (iv) the February Notes, if the holders of the February Notes are being requested to
consent to such action with respect to the terms of the February Notes or the February Indenture,
(v) the November 1998 Notes, if the holders of the November 1998 Notes are being requested to
consent to such action with respect to the terms of the November 1998 Notes or the November 1998
Indenture, (vi) the November 1999 Notes, if the holders of the November 1999 Notes are being
requested to consent to such action with respect to the terms of the November 1999 Notes or the
November 1999 Indenture, (vii) the January Notes, if the holders of the January Notes are being
requested to consent to such action with respect to the terms of the January Notes or the January
Indenture and (viii) any other issue or series of unsubordinated, unsecured notes issued by the
Company (including any other series of the Securities), if such notes or the indenture pursuant to
which such notes were issued both (A) require the consent of the holders of such notes to such
action and (B) provide that the holders thereof will vote with the holders of that series of the
Securities with respect to such action.

     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 amount of Securities of this series at the time Outstanding a direction inconsistent with
such request, and shall have failed to institute any such proceeding, for 60 days after receipt of
such notice, request and offer of indemnity. The foregoing shall not apply to any suit instituted
by the Holder of this Security for the enforcement of any payment of principal hereof or any
premium or interest hereon on or after the respective due dates expressed herein.

- 2 -

 

     No reference herein to the Indenture and no provision of this Security or of the Indenture
shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay
the principal of and any premium and interest on this Security at the times, place and rate, and in
the coin or currency, herein prescribed.

     As provided in the Indenture and subject to certain limitations therein set forth, the
transfer of this Security may be registered in the Security Register, upon surrender of this
Security for registration of transfer at the office or agency of the Company in any place where the
principal of and any premium and interest on this Security are payable, duly endorsed by, or
accompanied by a written instrument of transfer in form satisfactory to the Company and the
Security Registrar duly executed by, the Holder hereof or his attorney duly authorized in writing,
and thereupon one or more new Securities of this series and of like tenor, of authorized
denominations and for the same aggregate principal amount, will be issued to the designated
transferee or transferees.

     The Securities of this series are issuable only in registered form without coupons in
denominations of $1,000 and any integral multiple thereof. As provided in the Indenture and subject
to certain limitations therein set forth, Securities of this series are exchangeable for a like
aggregate principal amount of Securities of this series and of like tenor of a different authorized
denomination, as requested by the Holder surrendering the same.

     No service charge shall be made for any such registration of transfer or exchange, but the
Company may require payment of a sum sufficient to cover any tax or other governmental charge
payable in connection therewith.

     Prior to due presentment of this Security for registration of transfer, the Company, the
Trustee and any agent of the Company or the Trustee may treat the Person in whose name this
Security is registered as the owner hereof for all purposes, whether or not this Security be
overdue, and neither the Company, the Trustee nor any such agent shall be affected by notice to the
contrary.

     No recourse for the payment of the principal of (and premium, if any) or interest, if any, on
this Security, or for any claim based hereon or otherwise in respect hereof, and no recourse under
or upon any obligation, covenant or agreement of the Company in the Indenture or in any indenture
supplemental thereto, or in any Security, or because of the creation of any indebtedness
represented thereby, shall be had against any incorporator, or against any past, present or future
partner, shareholder, other equity holder, officer, director, employee or controlling person, as
such, of the Company or of any successor corporation, either directly or through the Company or any
successor corporation, whether by virtue of any constitution, statute or rule of law, or by the
enforcement of any assessment or penalty or otherwise, all such liability, either at common law or
in equity or by constitution or statute, being, by the acceptance hereof and as part of the
consideration for the issue hereof, expressly waived and released.

     THIS SECURITY SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF
NEW YORK.

     All terms used in this Security which are defined in the Indenture shall have the meanings
assigned to them in the Indenture.

	$4,000,000

	 	Vienna, Virginia

June 17, 2005

     FOR VALUE RECEIVED, the undersigned, VISUAL NETWORKS, INC., a Delaware corporation, VISUAL
NETWORKS INTERNATIONAL OPERATIONS, INC., a Delaware corporation, VISUAL NETWORKS OPERATIONS, INC.,
a Delaware corporation, AVESTA TECHNOLOGIES, LLC, a Delaware limited liability company and NET2NET,
LLC, a Delaware limited liability company (each a “Borrower” and collectively, the “Borrowers”)
jointly and severally promise to pay to the order of SILICON VALLEY BANK, a California-chartered
bank doing business in Virginia as “Silicon Valley East” (“Bank”), at such place as the holder
hereof may designate, in lawful money of the United States of America, the aggregate unpaid
principal amount of all advances (“Advances”) made by Bank to Borrowers in accordance with the
terms and conditions of the Loan and Security Agreement among Borrowers and Bank of even date
herewith, (as amended from time to time, the “Loan Agreement”), up to a maximum principal amount of
Four Million Dollars ($4,000,000) (“Principal Sum”), or so much thereof as may be advanced or
readvanced and remains unpaid. The unpaid Principal Sum, together with interest thereon at the
rate or rates provided in the Loan Agreement, shall be payable as set forth in the Loan Agreement.

     The fact that the balance hereunder may be reduced to zero from time to time pursuant to the
Loan Agreement will not affect the continuing validity of this Note or the Loan Agreement, and the
balance may be increased up to the Principal Sum after any such reduction to zero.

     Each Borrower further agrees that, if any payment made by any Borrower or any other person is
applied to this Note and is at any time annulled, set aside, rescinded, invalidated, declared to be
fraudulent or preferential or otherwise required to be refunded or repaid, or the proceeds of any
property hereafter securing this Note is required to be returned by the Bank to any Borrower, its
estate, trustee, receiver or any other party, including, without limitation, such Borrower, under
any bankruptcy law, state or federal law, common law or equitable cause, then, to the extent of
such payment or repayment, such Borrower’s liability hereunder (and any lien, security interest or
other collateral securing such liability) shall be and remain in full force and effect, as fully as
if such payment had never been made, or, if prior thereto any such lien, security interest or other
collateral hereafter securing such Borrower’s liability hereunder shall have been

 

 

released or
terminated by virtue of such cancellation or surrender, this Note
(and such lien, security interest or other collateral) shall be reinstated in full force and effect, and such
prior cancellation or surrender shall not diminish, release, discharge, impair or otherwise affect
the obligations of such Borrower in respect of the amount of such payment (or any lien, security
interest or other collateral securing such obligation).

     This Note is the “Revolving Promissory Note” described in the Loan Agreement, to which
reference is hereby made for a more complete statement of the terms and conditions under which the
loans and advances evidenced hereby are made. This Note is secured as provided in the Loan
Agreement. All capitalized terms used herein and not otherwise defined shall have the meanings
given to such terms in the Loan Agreement.

     Borrowers irrevocably waive the right to direct the application of any and all payments at any
time hereafter received by Bank from or on behalf of Borrowers and Borrowers irrevocably agree that
Bank shall have the continuing exclusive right to apply any and all such payments against the then
due and owing obligations of Borrowers as Bank may deem advisable. In the absence of a specific
determination by Bank with respect thereto, all payments shall be applied in the following order:
(a) then due and payable fees and expenses; (b) then due and payable interest payments and
mandatory prepayments; and (c) then due and payable principal payments and optional prepayments.

     Bank is hereby authorized by Borrowers to endorse on Bank’s books and records each Advance
made by Bank under this Note and the amount of each payment or prepayment of principal of each such
Advance received by Bank; it being understood, however, that failure to make any such endorsement
(or any error in notation) shall not affect the obligations of Borrowers with respect to Advances
made hereunder, and payments of principal by Borrowers shall be credited to Borrowers
notwithstanding the failure to make a notation (or any errors in notation) thereof on such books
and records.

     The occurrence of any one or more of the following events shall constitute an event of default
(individually, an “Event of Default” and collectively, the “Events of Default”) under the terms of
this Note:

          (a) The failure of Borrowers to pay to Bank when due any and all amounts payable by Borrowers
to Bank under the terms of this Note; or

          (b) The occurrence of an Event of Default (as defined therein) under the terms and conditions
of any of the other Loan Documents.

     Upon the occurrence of an Event of Default, at the option of Bank, all amounts payable by
Borrowers to Bank under the terms of this Note shall immediately become due and payable by
Borrowers to Bank without notice to Borrowers or any other person, and Bank shall have all of the
rights, powers, and remedies available under the terms of this Note, any of the other Loan

2

 

Documents and all applicable laws. Borrowers and all endorsers, guarantors, and other parties
who may now or in the future be primarily or secondarily liable for the payment of the
indebtedness evidenced by this Note hereby severally waive presentment, protest and demand, notice
of protest, notice of demand and of dishonor and non-payment of this Note and expressly agree that
this Note or any payment hereunder may be extended from time to time without in any way affecting
the liability of Borrowers, guarantors and endorsers.

     In the event this Note is not paid when due or any installment due hereunder is not paid
within fifteen (15) days of the date when due, whether by maturity or acceleration, Borrower hereby
appoints and designates Mary Zinsner, Esq., Borrower’s duly constituted attorney-in-fact to confess
judgment pursuant to the provisions of Section 8.01-432 of the Code of Virginia of 1950, as
amended, against Borrower for all principal of and interest due and payable under this Note upon
the occurrence of an Event of Default, together with attorneys’ fees and collection fees as
provided herein (to the extent permitted by law), which judgment shall be confessed in the Clerk’s
Office of the Circuit Court of Fairfax County, Virginia. Upon request of Bank, Borrower will
execute an amendment or other agreement substituting attorneys-in-fact appointed to act for
Borrower hereunder.

     Borrowers jointly and severally promise to pay all costs and expense of collection of this
Note and to pay all reasonable attorneys’ fees incurred in such collection, whether or not there is
a suit or action, or in any suit or action to collect this Note or in any appeal thereof. No delay
by Bank in exercising any power or right hereunder shall operate as a waiver of any power or
right. Time is of the essence as to all obligations hereunder.

     This Note is issued pursuant to the Loan Agreement, which shall govern the rights and
obligations of Borrowers with respect to all obligations hereunder.

     Borrowers acknowledge and agree that this Note shall be governed by the laws of the
Commonwealth of Virginia, excluding conflicts of laws principles, even though for the convenience
and at the request of Borrowers, this Note may be executed elsewhere.

     EACH BORROWER ACCEPTS FOR ITSELF AND IN CONNECTION WITH ITS PROPERTIES, UNCONDITIONALLY, THE
NON-EXCLUSIVE JURISDICTION OF ANY STATE OR FEDERAL COURT OF COMPETENT JURISDICTION IN THE
COMMONWEALTH OF VIRGINIA IN ANY ACTION, SUIT, OR PROCEEDING OF ANY KIND, AGAINST IT WHICH ARISES
OUT OF OR BY REASON OF THIS AGREEMENT; PROVIDED, HOWEVER, THAT IF FOR ANY REASON BANK CANNOT AVAIL
ITSELF OF THE COURTS OF VIRGINIA, EACH BORROWER ACCEPTS JURISDICTION OF THE COURTS AND VENUE IN
SANTA CLARA COUNTY, CALIFORNIA. EACH BORROWER AND BANK EACH HEREBY WAIVE THEIR RESPECTIVE RIGHTS
TO A JURY TRIAL OF ANY CLAIM OR CAUSE OF ACTION BASED UPON OR ARISING OUT OF ANY OF THE LOAN
DOCUMENTS OR ANY OF THE TRANSACTIONS CONTEMPLATED THEREIN, INCLUDING CONTRACT CLAIMS, TORT CLAIMS,
BREACH OF DUTY

3

 

CLAIMS,
AND ALL OTHER COMMON LAW OR STATUTORY CLAIMS. EACH PARTY RECOGNIZES AND AGREES THAT THE FOREGOING WAIVER CONSTITUTES A MATERIAL INDUCEMENT FOR IT TO
ENTER INTO THIS AGREEMENT. EACH PARTY REPRESENTS AND WARRANTS THAT IT HAS REVIEWED THIS WAIVER
WITH ITS LEGAL COUNSEL AND THAT IT KNOWINGLY AND VOLUNTARILY WAIVES ITS JURY TRIAL RIGHTS FOLLOWING
CONSULTATION WITH LEGAL COUNSEL.

     The JOINT AND SEVERAL obligations of each Borrower under this Note shall be absolute,
irrevocable and unconditional and shall remain in full force and effect until the outstanding
principal of and interest on this Note and all other Obligations or amounts due hereunder and under
the Loan Agreement and the Loan Documents shall have been indefeasibly paid in full in cash in
accordance with the terms thereof.
