	No.                     	 	 	 	New York, NY

 [Date] 
  
 FOR VALUE RECEIVED, the undersigned, FIRST AVENUE NETWORKS, INC., a Delaware corporation (the “Company”), hereby promises
to pay to [Name], or its registered assigns, at [Address], the principal sum of [AMOUNT] ($                ), or so much thereof as shall not
have been prepaid, on December 20, 2008 (the “Maturity Date”), with interest (computed on the basis of a 360-day year of twelve 30-day months) on the principal amount hereof from time to time outstanding and unpaid, payable as
provided in the next succeeding paragraph hereof, at the rate of 9% per annum from the date of issuance hereof (being the date first above written), or the most recent date to which interest has been paid hereon, to but excluding the date on which
said principal amount shall be paid in full. 
  
 The Company shall
pay interest (a) on each Quarterly Date (as hereinbelow defined) until the date on which the principal of and all accrued and unpaid interest on this Note shall be paid in full, in cash, commencing on the first such Quarterly Date occurring after
the date of issuance hereof, (b) on the Maturity Date, and (c) upon the payment or prepayment of any principal owing under this Note (but only on the principal amount so prepaid or paid). Prior to the Maturity Date, if but only if and so long as no
Event of Default shall have occurred and be continuing under the Purchase Agreement hereinbelow referred to, the Company may, in lieu of the payment in cash on any Quarterly Date or other date on which a payment of interest shall be due and payable
hereon and on all other Notes of the series of which this Note is one (this Note and such other Notes and the PIK Notes hereinbelow referred to, collectively, the “Notes” and individually a “Note”) of the unpaid
interest then due and payable hereon and thereon, pay such interest through the issuance and delivery of additional Notes to the registered holder hereof and the registered holders of the other Notes, each such additional Note to be dated its date
of issuance, and to be in like form and have like tenor and terms as this Note (including with respect to payment of interest thereon through issuance of additional Notes), except for its date of issuance and original principal amount (each such
additional Note being sometimes herein called a “PIK Note”). Each PIK Note so issued and delivered to the registered holder of any Note (including this Note) shall be in a principal amount equal to the amount of interest then due
and payable with respect to such Note and not then being paid in cash. Notwithstanding the foregoing or any other provision of the Purchase Agreement or this Note or any other Note, however, no PIK Notes shall be issued on the Maturity Date, or on
any other date on which the entire outstanding principal balance of the Senior Secured Notes shall be due and payable, whether by acceleration, notice of prepayment or otherwise. For purposes of this Note the term “Quarterly Date”
shall mean the last day of each March, June, September and December; provided that if any such day is not a Business Day, then such Quarterly Date shall be the next succeeding Business Day and interest shall accrue by reason of such extension.

  
 The principal of the Notes (including this Note) may be
prepaid, in whole or ratably in part, at any time upon not less than five (5) nor more than twenty (20) days’ prior written notice to the holders thereof, together with all interest then accrued and unpaid thereon (or on the portion thereof
being so prepaid, as the case may be), but without premium or penalty. For the avoidance of doubt, subject to the penultimate sentence of the immediately preceding paragraph in respect of a prepayment in whole, such interest may be paid by issuance
and delivery of additional PIK Notes. 
  

 All payments of principal of and interest on this Note shall (except as aforesaid with respect to issuance of PIK Notes
in payment of interest hereon) be in such coin or currency of the United States of America as at the time of payment shall be legal tender for payment of public and private debts. 
  
 This Note is one of a series of Notes issued pursuant to, is entitled to the benefits of, and is subject to the terms of, the Senior Secured
Note and Class A Warrant Purchase Agreement, dated as of December 20, 2001, as amended by the First Amendment to Senior Secured Note and Class A Warrant Purchase Agreement, dated as of January 26, 2004 (as so amended, the “Purchase
Agreement”), among the Company and the several Purchasers named in Schedule I thereto, providing for the issuance of the 9% Senior Secured Notes of the Company, in the original aggregate principal amount (before the issuance of any PIK
Notes) of $10,975,225.00. The indebtedness evidenced by this Note is secured to the extent and in the manner set forth in certain Security Agreements referred to in the Purchase Agreement. 
  
 In case of an Event of Default (as defined in the Purchase Agreement) shall occur and be
continuing, the principal of this Note may be declared due and payable in the manner and with the effect provided in the Purchase Agreement. 
  

 This Note shall be governed by and construed in accordance with the laws of the State of New York.

out of or related to any breach or inaccuracy of any representation or warranty of the Company contained in this Agreement which shall survive for the applicable statute of limitations; (ii) any non-fulfillment or breach of any covenant oragreement
of the Company contained in this Agreement, the Registration Rights Agreement or the Warrants; or (iii) incurred in connection with any suit, action, proceeding, claim, 
  

 -16- 

 investigation, liability or obligation (an “Action or Proceeding”) against any
Indemnified Person arising out of or in connection with this Agreement, the Registration Rights Agreement or the Warrants (or any other document or instrument executed pursuant hereto or thereto), or the transactions contemplated herein or therein,
other than (a) Losses that are finally determined in such Action or Proceeding to be primarily and directly a result of (1) the gross negligence or willful misconduct of such Indemnified Person, (2) a breach of a fiduciary duty, if any, owed by such
Indemnified Person to the Company, (3) the knowing violation of applicable law by such Indemnified Person, or (4) a transaction from which such Indemnified Person received an improper personal benefit, or (b) Losses that are the subject of the
indemnification agreement entered into by the Company and such Indemnified Person pursuant to the Registration Rights Agreement, as to which Losses such indemnification agreement, rather than this Section 6.13 shall apply. The Company agrees
to reimburse each Indemnified Person promptly for all such Losses as they are incurred by such Indemnified Person after the Company receives a written undertaking by or on behalf of such Indemnified Person to reimburse the Company for any payments
made by the Company to such Indemnified Person if it is finally determined in such Action or Proceeding that such Indemnified Person is not entitled to indemnification pursuant to clause (iii) above. The obligations of the Company to each

Warrants. THE COMPANY AND THE INVESTOR INTEND THAT THE INDEMNIFIED PERSONS BE INDEMNIFIED FROM LIABILITIES FOR THEIR OWN NEGLIGENCE PURSUANT TO THIS SECTION 6.13. 
  
 (a) Each Investor shall indemnify and hold harmless the Company and each of its agents, officers, directors,
employees, representatives or affiliates (collectively, the “Company Indemnitees”) against any and all Losses sustained by the Company Indemnitees resulting from or arising out of, or connected with any material inaccuracy, breach
of, or nonfulfillment of any representation or warranty made by or other obligation of such Investor contained in this Agreement (including the Exhibits and Schedules hereto), the Registration Rights Agreement or the Warrants; provided,
however, that Losses that are the subject of the indemnification agreement entered into by the Company and such Indemnified Person pursuant to the Registration Rights Agreement or the Warrants shall be governed by such indemnification agreement,
rather than this Section 6.13. 
  
 (b)
Promptly after receipt by an Indemnified Person or a Company Indemnitee under this Section 6.13 of notice of the threat or commencement of any Action or Proceeding, such indemnified party will, if a claim in respect thereof is to be made against an
indemnifying party under this Section 6.13, notify the indemnifying party in writing of the claim; but the omission so to notify the indemnifying party will not relieve it from any liability which it may have to any indemnified party under the
indemnity agreement contained in this Section 6.13 except to the extent it is materially prejudiced as a result of such failure. In case any such action is brought against any Indemnified Person or a Company Indemnitee and such indemnified party
seeks or intends to seek indemnity from an indemnifying party, the indemnifying party will be entitled to participate in, and, to the extent that it may wish, jointly with all other indemnifying parties similarly notified, to assume the defense
thereof with counsel reasonably satisfactory tosuch indemnified party; provided, however, if the defendants in any such action include both the indemnified party and the indemnifying party and the indemnified party shall have reasonably

  

 -17- 

 concluded that there may be a conflict between the positions of the indemnifying party and the
indemnified party in conducting the defense of any such action or that there may be legal defenses available to it or other indemnified parties that are different from or additional to those available to the indemnifying party, the indemnified party
or parties shall have the right to select separate counsel to assume such legal defenses and to otherwise participate in the defense of such action on behalf of such indemnified party or parties. Upon receipt of notice from the indemnifying party to
such indemnified party of its election so to assume the defense of such action and approval by the indemnified party of counsel, which approval shall not be unreasonably withheld, the indemnifying party will not be liable to such indemnified party
under this Section 6.13 for any legal or other expenses subsequently incurred by such indemnified party in connection with the defense thereof unless: (i) the indemnified party shall have employed such counsel in connection with the assumption of
legal defenses in accordance with the proviso to the preceding sentence (it being understood, however, that the indemnifying party shall not be liable for the expenses of more than one separate counsel representing all of the similarly situated
indemnified parties who are parties to such action) or (ii) the indemnifying party shall not have employed counsel reasonably satisfactory to the indemnified party to represent the indemnified party within a reasonable time after notice of
commencement of action, in each of which cases the reasonable fees and expenses of counsel shall be at the expense of the indemnifying party. 
  
 6.14 No Commitment for Additional Financing. The Company acknowledges and agrees that Investor has not made any representation,
undertaking, commitment or agreement to provide or assist the Company in obtaining any financing, investment or other assistance, other than the purchase of the Securities as set forth in Section 1.1 and subject to the conditions set forth in
Section 4. Investor shall have the right, in its sole and absolute discretion, to refuse or decline to participate in any other financing of or investment in the Company, and shall have no obligation to assist or cooperate with the Company in
