Amendment to 8% Senior Secured Promissory Note



 
Exhibit 4.6

 
AMERICAN TECHNOLOGY CORPORATION

 
AMENDMENT TO 8% SENIOR SECURED PROMISSORY
NOTE 
 
This Amendment to 8% Senior Secured
Promissory Note (the “Amendment”) is made as of February 26, 2003, among AMERICAN TECHNOLOGY CORPORATION (the “Company”) and the holders of 8% Senior Secured Promissory Notes (the “Notes”) listed on Exhibit A
attached hereto (“Holders”, and individually, a “Holder”). 
 
WHEREAS, the Notes may be amended, waived or modified upon the written consent of the Company and the holders of at least a majority of the face amount of all then outstanding Notes; and 
 
WHEREAS, the Company and the holders of at least a majority of
the face amount of all the outstanding Notes desire to amend the Notes. 
 
The Company and Holders therefore agree as follows: 
 
1.    Voluntary Conversion.    Notwithstanding anything to the contrary contained in the Notes, any Holder may request to convert all or any portion of
the principal balance of its Note (“Voluntary Conversion”) into Equity Securities (as defined in Section 6.2 of the Notes). Upon acceptance of such request by the Company in its sole discretion, such request shall be deemed an optional
redemption by the Company pursuant to Section 6.1 of the Note, except that the second sentence of Section 6.1 shall not apply. The price of the redemption for the portion of principal to be converted shall be calculated pursuant to Section 6.3.1 of
the Notes, using the closing date for the purchase of the Equity Securities as the Redemption Date. Such redemption price shall be applied to the purchase price for the Equity Securities; provided however, that the Company may, in its sole
discretion, pay all or a portion of the accrued but unpaid interest on the Redemption Principal and the Early Retirement Premium (each as defined in Section 6.3.1) in cash to the converting Holder instead of applying such amounts to the purchase
price for the Equity Securities (notwithstanding the second sentence of Section 6.1). 
 
2.    Mandatory Redemption.    Section 6.2 of the Notes is amended to clarify that amounts applied to the purchase price for Equity Securities by virtue
of Voluntary Conversions are not to be deemed gross proceeds received by the Company from sale of Equity Securities for purposes of determining when a Qualified Financing has occurred. 
 
3.    Due Date.    The due date for the Notes is
extended from December 31, 2003 to December 31, 2004, by replacing the date “December 31, 2003” with “December 31, 2004” in each place it appears in the Notes. 
 
4.    Confirmation of Notes.    All other terms and provisions
of the Notes not amended remain in full force and effect. 
 
5.    No Waiver.    Except as specifically provided in this Amendment, the holders of the Notes have no obligation, nor have such holders made any commitment or representation, to any
other amendment or modification of the Notes. 
 









6.    No Novation.    This Amendment does
not constitute a novation or a renewal of the Notes, but rather a modification of the Notes. 
 
7.    General.    This Amendment is governed by and construed under the laws of the State of California, excluding that body of law relating to conflicts
of law. This Amendment, the Notes and the related Security Agreement represent the entire agreement between the parties and neither party shall be bound by any prior discussions, proposals or oral agreements. 
 
8.    Waiver and
Amendment.    Any provision of the Amendment may be amended, waived or modified upon the written consent of the Company and the holders of at least a majority of the face amount of all then outstanding Notes. 
 
9.    Counterparts.    This Amendment may be executed in counterparts, each of which shall be deemed an original and all of which together shall constitute one document.
