20

to close the Subsequent Financing on the scheduled closing date with a third party; provided that all of the material terms and conditions of the closing are the same as those provided to the Purchaser in the Rights Notice.  If the closing of the proposed Subsequent Financing does not occur within five (5) Trading Days of that date, any closing of the contemplated Subsequent Financing or any other Subsequent Financing shall be subject to all of the provisions of this Section 3.20(a), including, without limitation, the delivery of a new Rights Notice.  The provisions of this Section 3.20(a) shall not apply to issuances of securities in a Permitted Financing.

Section 5.1

Legend.  The certificate representing the Series F Warrant shall be stamped or otherwise imprinted with a legend substantially in the following form (in addition to any legend required by applicable state securities or “blue sky” laws):

THE SECURITIES REPRESENTED BY THIS CERTIFICATE (THE “SECURITIES”) HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE “SECURITIES ACT”) OR ANY STATE SECURITIES LAWS AND MAY NOT BE SOLD, TRANSFERRED OR OTHERWISE DISPOSED OF UNLESS REGISTERED UNDER THE SECURITIES ACT AND UNDER APPLICABLE STATE SECURITIES LAWS OR AMBIENT CORPORATION SHALL HAVE RECEIVED AN OPINION OF COUNSEL THAT REGISTRATION OF SUCH SECURITIES UNDER THE SECURITIES ACT AND UNDER THE PROVISIONS OF APPLICABLE STATE SECURITIES LAWS IS NOT REQUIRED.

The Company shall issue irrevocable instructions to its transfer agent, and any subsequent transfer agent, to issue certificates, registered in the name of the Purchaser or its respective nominee(s), for the Warrant Shares in such amounts as specified from time to time by the Purchaser to the Company upon exercise of the Series F Warrant in the form of Exhibit D attached hereto (the “Irrevocable Transfer Agent Instructions”).  Prior to registration of the Warrant Shares under the Securities Act, all such certificates shall bear the restrictive legend specified in this Section 5.1. Certificates evidencing the Warrant Shares shall not contain any legend (including the legend set forth in Section 5.1 hereof), (i) while a registration statement (including the Registration Statement) covering the resale of such security is effective under the Securities Act, or (ii) follow ing any sale of Warrant Shares pursuant to Rule 144, or (iii) if such Warrant Shares are eligible for sale under Rule 144 without regard to volume or manner of sale limitations, or (iv) if such legend is not required under applicable requirements of the Securities Act (including judicial interpretations and pronouncements issued by the Staff of the Commission).  The Company shall cause its counsel to issue a legal opinion to the Company’s transfer agent promptly after the effective date of a registration statement covering such Warrant Shares, if required by the Company’s transfer agent, to effect the removal of the legend hereunder.  If all or any portion of the Series F Warrant is exercised at a time when there is an effective registration statement to cover the resale of the Warrant Shares, such Warrant Shares shall be issued free of all legends.  The Company agrees that following the effective date of the registration statement covering Warrant Shares or at such time as such legend is no longer required under this Section 5.1, it will, no later than three (3) Trading Days following the delivery by a Purchaser to the Company or the Company’s transfer agent of a certificate representing Warrant Shares issued with a restrictive legend (such date, the “Delivery Date”), deliver or cause to be delivered to the Purchaser a certificate representing such Warrant Shares that is free from all restrictive and other legends.  The Company may not make any notation on its records or give instructions to any transfer agent of the Company that enlarge the restrictions on transfer set forth in this Section. Whenever a certificate representing the Warrant Shares is required to be issued to a Purchaser without a legend, in lieu of delivering physical certificates representing the Warrant Shares, provided the Company’s transfer agent is participating in the Depository Trust Company (“DTC”) Fast Automated Securities Transfer program, the Com pany shall use its reasonable best efforts to cause its transfer agent to electronically transmit the Warrant Shares to a Purchaser by crediting the account of the Purchaser’s Prime Broker with DTC through its Deposit Withdrawal Agent Commission (“DWAC”) system (to the extent not inconsistent with any provisions of this Agreement).  

Section 5.2

Liquidated Damages.  The Company understands that a delay in the delivery of unlegended certificates for the Warrant Shares as set forth in Section 5.1 hereof beyond the Delivery Date could

29

result in economic loss to the Purchaser.  If the Company fails to deliver to the Purchaser such shares via DWAC or a certificate or certificates pursuant to this Section hereunder by the second Trading Day following the Delivery Date, the Company shall pay to the Purchaser, in cash, $10,000 per Trading Day for each Trading Day after the Delivery Date until such certificate is delivered (which amount shall be paid as liquidated damages and not as a penalty).  Nothing herein shall limit the Purchaser’s right to pursue actual damages for the Company’s failure to deliver certificates representing any Securities as required by the Transaction Documents, and the Purchaser shall have the right to pursue all remedies available to it at law or in equity including, without limitation, a decree of specific performance and/or injunctive relief.

Section 5.3

Sales by Purchaser.  The Purchaser agrees that the removal of the restrictive legend from certificates representing Securities as set forth in Section 5.1 is predicated upon the Company’s reliance that the Purchaser will sell any securities pursuant to either the registration requirements of the Securities Act, including any applicable prospectus delivery requirements, or an exemption therefrom.

ARTICLE VI

INDEMNIFICATION

Section 6.1

Company Indemnity.  The Company agrees to indemnify and hold harmless the Purchaser (and its respective directors, officers, affiliates, agents, successors and assigns) from and against any and all losses, liabilities, deficiencies, costs, damages and expenses (including, without limitation, reasonable attorneys’ fees, charges and disbursements) incurred by the Purchaser as a result of (a) any inaccuracy in or breach of the representations, warranties or covenants made by the Company herein as such are incurred, except to the extent that such amounts result from the Purchaser’s failure to perform any covenant or agreement contained in this Agreement or the Purchaser’s illegal or willful misconduct, gross negligence, misrepresentations, recklessness or bad faith (in each case, as determined by a non-appealable judgment to such effect or a judgment not appealed in the requisite time period) in performing its obligations under this Agreement or (b) any action instituted against the Purchaser, or any of its respective Affiliates, by any stockholder of the Company who is not an Affiliate of the Purchaser, with respect to any of the transactions contemplated by the Transaction Documents (unless such action is based upon a breach of the Purchaser’s representations, warranties or covenants under the Transaction Documents or any agreements or understandings the Purchaser may have with any such stockholder or any violations by the Purchaser of state or federal securities laws or any conduct by the Purchaser which constitutes fraud, gross negligence, willful misconduct or malfeasance).  

Section 6.2

Indemnification Procedure.  Any party entitled to indemnification under this Article VI (an “indemnified party”) will give written notice to the indemnifying party of any matter giving rise to a claim for indemnification; provided, that the failure of any party entitled to indemnification hereunder to give notice as provided herein shall not relieve the indemnifying party of its obligations under this Article VI except to the extent that the indemnifying party is actually prejudiced by such failure to give notice.  In case any such action, proceeding or claim is brought against an indemnified party in respect of which indemnification is sought hereunder, the indemnifying party shall be entitled to participate in and, unless in the reasonable judgment of the indemnifying party a conflict of interest between it and the indemnified party exists with respect to such action, proceeding or claim (in which case the indemnifying party shall be responsible for the reasonable fees and expenses of one separate counsel for the indemnified parties), to assume the defense thereof with counsel reasonably satisfactory to the indemnified party.  In the event that the indemnifying party advises an indemnified party that it will contest such a claim for indemnification hereunder, or fails, within thirty (30) days of receipt of any indemnification notice to notify, in writing, such person of its election to defend, settle or compromise, at its sole cost and expense, any action, proceeding or claim (or discontinues its defense at any time after it commences such defense), then the indemnified party may, at its option, defend, settle or otherwise

30

compromise or pay such action or claim.  In any event, unless and until the indemnifying party elects in writing to assume and does so assume the defense of any such claim, proceeding or action, the indemnified party’s costs and expenses arising out of the defense, settlement or compromise of any such action, claim or proceeding shall be losses subject to indemnification hereunder.  The indemnified party shall cooperate fully with the indemnifying party in connection with any negotiation or defense of any such action or claim by the indemnifying party and shall furnish to the indemnifying party all information reasonably available to the indemnified party which relates to such action or claim.  The indemnifying party shall keep the indemnified party fully apprised at all times as to the status of the defense or any settlement negotiations with respect thereto.  If the indemnifying party elec ts to defend any such action or claim, then the indemnified party shall be entitled to participate in such defense (but not control) with counsel of its choice at its sole cost and expense.  The indemnifying party shall not be liable for any settlement of any action, claim or proceeding effected without its prior written consent.  Notwithstanding anything in this Article VI to the contrary, the indemnifying party shall not, without the indemnified party’s prior written consent, settle or compromise any claim or consent to entry of any judgment in respect thereof which imposes any future obligation on the indemnified party or which does not include, as an unconditional term thereof, the giving by the claimant or the plaintiff to the indemnified party of a release from all liability in respect of such claim.  The indemnification obligations to defend the indemnified party required by this Article VI shall be made by periodic payments of the amount thereof during the course of investigation or defense, as and when bills are received or expense, loss, damage or liability is incurred, so long as the indemnified party shall refund such moneys if it is ultimately determined by a court of competent jurisdiction that such party was not entitled to indemnification.  The indemnity agreements contained herein shall be in addition to (a) any cause of action or similar rights of the indemnified party against the indemnifying party or others, and (b) any liabilities the indemnifying party may be subject to pursuant to the law.  No indemnifying party will be liable to the indemnified party under this Agreement to the extent, but only to the extent that a loss, claim, damage or liability is attributable to the indemnified party’s breach of any of the representations, warranties or covenants made by such party in this Agreement or in the other Transaction Documents.

Attn:  _____________

Ladies and Gentlemen:

Reference is made to that certain Securities Purchase Agreement (the “Purchase Agreement”), dated as of April __, 2008, by and among Ambient Corporation, a Delaware corporation (the “Company”), and the Purchaser named therein (the “Purchaser”) pursuant to which the Company is issuing to the Purchaser a warrant (the “Warrant”) to purchase shares of the Company’s common stock, par value $0.001 per share (the “Common Stock”).  This letter shall serve as our irrevocable authorization and direction to you (provided that you are the transfer agent of the Company at such time) to issue shares of Common Stock upon exercise of the Warrant (the “Warrant Shares”) to or upon the order of the Purchaser from time to time upon (i) surrender to you of a properly completed and duly executed Exerc ise Notice, as the case may be, in the form attached hereto as Exhibit I (ii) a copy of the Warrant (with the original Warrant delivered to the Company) being exercised (or, in each case, an indemnification undertaking with respect to such Warrant in the case of loss, theft or destruction), and (iii) delivery of a treasury order or other appropriate order duly executed by a duly authorized officer of the Company.  So long as you have previously received written confirmation from counsel to the Company that a registration statement covering resales of Warrant Shares, as applicable, has been declared effective by the Securities and Exchange Commission (the “SEC”) under the Securities Act of 1933, as amended (the “1933 Act”), and no subsequent notice by the Company or its counsel of the suspension or termination of its effectiveness, then certificates representing the Warrant Shares, as the case may be, shall not bear any legend restricting transfer of the Warran t Shares, as the case may be, thereby and should not be subject to any stop-transfer restriction.  Provided, however, that if you have not previously received written confirmation from counsel to the Company that a registration statement covering resales of the Warrant Shares, as applicable, has been declared effective by the SEC under the 1933 Act, then the certificates for the Warrant Shares shall bear the following legend:

“THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE SECURITIES ACT”), OR ANY STATE SECURITIES LAWS AND MAY NOT BE SOLD, TRANSFERRED OR OTHERWISE DISPOSED OF UNLESS REGISTERED UNDER THE SECURITIES ACT OR APPLICABLE STATE SECURITIES LAWS, OR AMBIENT CORPORATION SHALL HAVE RECEIVED AN OPINION OF ITS COUNSEL THAT REGISTRATION OF SUCH SECURITIES UNDER THE SECURITIES ACT AND UNDER THE PROVISIONS OF APPLICABLE STATE SECURITIES LAWS IS NOT REQUIRED.”

A form of written confirmation from counsel to the Company that a registration statement covering resales of the Warrant Shares has been declared effective by the SEC under the 1933 Act is attached hereto as Exhibit II.

Please execute this letter in the space indicated to acknowledge your agreement to act in accordance with these instructions.  Should you have any questions concerning this matter, please contact me at ___________.

FORM OF NOTICE OF EFFECTIVENESS

OF REGISTRATION STATEMENT

[Name and address of Transfer Agent]

Attn:  _____________

Re:

Ambient Corporation

Ladies and Gentlemen:

We are special counsel to Ambient Corporation, a Delaware corporation (the “Company”), and have represented the Company in connection with that certain Securities Purchase Agreement (the “Purchase Agreement”), dated as of April __, 2008, by and among the Company and the Purchaser named therein (the “Purchaser”) pursuant to which the Company issued to the Purchaser a warrant (the “Warrant”) to purchase shares of the Company’s common stock, par value $0.001 per share (the “Common Stock”).  Pursuant to the Purchase Agreement, the Company has also entered into a Registration Rights Agreement with the Purchaser (the “Registration Rights Agreement”), dated as of July 31, 2007, pursuant to which the Company agreed, among other things, to register the Registrable Securities (as defined in the Registration Rights Agreement), including the shares of Common Stock issuable upon exercise of the Warrants, under the Securities Act of 1933, as amended (the “1933 Act”).  In connection with the Company’s obligations under the Registration Rights Agreement, on ________________, 2008, the Company filed a Registration Statement on Form S-1 (File No. 333-________) (the “Registration Statement”) with the Securities and Exchange Commission (the “SEC”) relating to the resale of the Registrable Securities which names each of the present Purchaser as a selling stockholder thereunder.

In connection with the foregoing, we advise you that a member of the SEC’s staff has advised us by telephone that the SEC has entered an order declaring the Registration Statement effective under the 1933 Act at [ENTER TIME OF EFFECTIVENESS] on [ENTER DATE OF EFFECTIVENESS] and we have no knowledge, after telephonic inquiry of a member of the SEC’s staff, that any stop order suspending its effectiveness has been issued or that any proceedings for that purpose are pending before, or threatened by, the SEC and accordingly, the Registrable Securities are available for resale under the 1933 Act pursuant to the Registration Statement.
