14% Senior Secured Note due 2011

Capitalized terms used herein have the meanings assigned to them in the Indenture referred to below unless otherwise indicated.

(1) Interest. Grande Communications Holdings, Inc., a Delaware corporation (the “Company”), promises to pay interest on the principal amount of this Note at 14% per annum until maturity. The Company will pay interest semi-annually in arrears on April 1 and October 1 of each year, or if any such day is not a Business Day, on the next succeeding Business Day (each, an “Interest Payment Date”). Interest on the Notes will accrue from the most recent date to which interest has been paid or, if no interest has been paid, from the date of issuance; provided that if there is no existing Default in the payment of interest, and if this Note is authenticated between a record date referred to on the face hereof and the next succeeding Interest Payment Date, interest shall accrue from such next succeeding Interest Payment Date; provided further that the first Interest Payment Date shall be October 1, 2006. The Company will pay interest (including post-petition interest in any proceeding under any Bankruptcy Law) on overdue principal and premium, if any, from time to time on demand at a rate that is 0.50% per annum in excess of the rate then in effect; it will pay interest (including post-petition interest in any proceeding under any Bankruptcy Law) on overdue installments of interest (without regard to any applicable grace periods) from time to time on demand at the same rate to the extent lawful. Interest will be computed on the basis of a 360-day year of twelve 30-day months.

(2) Method of Payment. The Company will pay interest on the Notes (except defaulted interest) to the Persons who are registered Holders of Notes at the close of business on the March 15 or September 15 next preceding the Interest Payment Date, even if such Notes are canceled after such record date and on or before such Interest Payment Date, except as provided in Section 2.12 of the Indenture with respect to defaulted interest. The Notes will be payable as to principal, premium and interest at the office or agency of the Company maintained for such purpose within or without the City and State of New York, or, at the option of the Company, payment of interest may be made by check mailed to the Holders at their addresses set forth in the register of Holders; provided that payment by wire transfer of immediately available funds will be required with respect to principal of and interest and premium on all Notes the Holders of which will have provided wire transfer instructions to the Company or the Paying Agent. Such payment will be 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.

(3) Paying Agent and Registrar. Initially, U.S. Bank National Association, the Trustee under the Indenture, will act as Paying Agent and Registrar. The Company may change any Paying Agent or Registrar without notice to any Holder; provided, however, that the Company shall at all times maintain a Paying Agent office. The Company or any of its Subsidiaries may act in any such capacity.

(4) Indenture and Security Documents. The Company issued the Notes under an Indenture dated as of March 23, 2004 (the “Indenture”) among the Company, the Guarantors and the Trustee. The terms of the Notes include those stated in the Indenture and those made part of

R-1

the Indenture by reference to the TIA. The Notes are subject to all such terms, and Holders are referred to the Indenture and the TIA for a statement of such terms. To the extent any provision of this Note conflicts with the express provisions of the Indenture, the provisions of the Indenture shall govern and be controlling. The Notes are secured by a pledge of the Collateral pursuant to the Security Documents referred to in the Indenture.

(5) Optional Redemption.

(a) Except as set forth in subparagraph (b) of this Paragraph 5, the Company will not have the option to redeem the Notes prior to April 1, 2008. On or after April 1, 2008, the Company may redeem all or a part of the Notes upon not less than 10 days’ nor more than 60 days’ notice, at the redemption prices (expressed as percentages of principal amount) set forth below plus accrued and unpaid interest on the Notes redeemed to the applicable redemption date, if redeemed during the twelve-month period beginning on April 1 of the years indicated below, subject to the rights of Holders on the relevant record date to receive interest on the relevant interest payment date:

Unless the Company defaults in the payment of the redemption price, interest will cease to accrue on the notes or portions thereof called for redemption on the applicable redemption date.

(b) Notwithstanding the provisions of subparagraph (a) of this Paragraph 5, at any time prior to April 1, 2007, the Company may on any one or more occasions redeem Notes issued under the Indenture at a redemption price of 114% of the principal amount thereof, plus accrued and unpaid interest to the redemption date, with the net cash proceeds of one or more Equity Offerings; provided that at least 65% of the aggregate principal amount of Initial Notes originally issued under the Indenture on the Issue Date (excluding Notes held by the Company and its Subsidiaries) remains outstanding immediately after the occurrence of such redemption and the redemption occurs within 90 days of the date of the closing of such Equity Offering.

(6) Mandatory Redemption. The Company will not be required to make mandatory redemption or sinking fund payments with respect to the Notes.

(7) Repurchase at the Option of Holder.

(a) If there is a Change of Control, the Company will be required to make an offer (a “Change of Control Offer”) to each Holder to repurchase all or any part (equal to $1,000 or an integral multiple of $1,000) of each Holder’s Notes at a purchase price equal to 101% of the aggregate principal amount of Notes repurchased plus accrued and unpaid interest on the Notes repurchased to the date of purchase, subject to the rights of Holders on the relevant record date to receive interest due on the relevant interest payment date (the “Change of Control Payment”). Within 30 days following any Change of Control, the Company will mail a notice to

R-2

each Holder setting forth the procedures governing the Change of Control Offer as required by the Indenture.

(b) If the Company or a Restricted Subsidiary of the Company consummates any Asset Sales, within twenty days of each date on which the aggregate amount of Excess Proceeds exceeds $10.0 million, the Company will commence an offer to all Holders of Notes and all holders of other Indebtedness that is pari passu with the Notes containing provisions similar to those set forth in the Indenture with respect to offers to purchase or redeem with the proceeds of sales of assets (an “Asset Sale Offer”) in accordance with Section 4.10 of the Indenture to purchase the maximum principal amount of Notes and such other pari passu Indebtedness that may be purchased out of the Excess Proceeds at an offer price in cash in an amount equal to 100% of the principal amount thereof plus accrued and unpaid interest to the date of purchase, in accordance with the procedures set forth in the Indenture. If any Excess Proceeds remain unapplied after consumption of an Asset Sale Offer, the Company and its Restricted Subsidiaries may use those Excess Proceeds for any purpose not otherwise prohibited by the Indenture. If the aggregate principal amount of Notes and other pari passu Indebtedness surrendered by holders thereof exceeds the amount of Excess Proceeds, the Trustee shall select the Notes and other pari passu Indebtedness to be purchased on a pro rata basis. Holders of Notes that are the subject of an offer to purchase will receive notice of an Asset Sale Offer from the Company prior to any related purchase date and may elect to have such Notes purchased by completing the form entitled “Option of Holder to Elect Purchase” attached to the Notes.

(8) Notice of Redemption. Notice of redemption will be mailed at least 10 days but not more than 60 days before the redemption date to each Holder whose Notes are to be redeemed at its registered address, except that redemption notices may be mailed more than 60 days prior to a redemption date if the notice is issued in connection with a defeasance of the Notes or a satisfaction or discharge of the Indenture. Notes in denominations larger than $1,000 may be redeemed in part but only in whole multiples of $1,000, unless all of the Notes held by a Holder are to be redeemed. On and after the redemption date interest ceases to accrue on Notes or portions thereof called for redemption.

(9) Denominations, Transfer, Exchange. The Notes are in registered form without coupons in denominations of $1,000 and integral multiples of $1,000. The transfer of Notes may be registered and Notes may be exchanged as provided in the Indenture. The Registrar and the Trustee may require a Holder, among other things, to furnish appropriate endorsements and transfer documents and the Company may require a Holder to pay any taxes and fees required by law or permitted by the Indenture. The Company need not exchange or register the transfer of any Note or portion of a Note selected for redemption, except for the unredeemed portion of any Note being redeemed in part. Also, the Company need not exchange or register the transfer of any Notes for a period of 15 days before a selection of Notes to be redeemed or during the period between a record date and the corresponding Interest Payment Date.

R-4

Holders may not enforce the Indenture or the Notes except as provided in the Indenture. Subject to certain limitations, Holders of a majority in principal amount of the then outstanding Notes may direct the Trustee in its exercise of any trust or power. The Trustee may withhold from Holders of the Notes notice of any continuing Default or Event of Default (except a Default or Event of Default relating to the payment of principal of, premium or interest on, any Note) if it in good faith determines that withholding notice is in their interest. The Holders of a majority in
