SECURITIES PURCHASE AGREEMENT

This SECURITIES PURCHASE AGREEMENT dated as of April 23, 2008 (this Agreement) by and among Ambient Corporation, a Delaware corporation (the Company) and Vicis Capital Master Fund, a series of the Vicis Capital Master Trust, a trust formed under the laws of the Cayman Islands (Vicis or the Purchaser).

WHEREAS, the Company wishes to undertake a warrant financing, and pursuant to the terms and conditions of this Agreement, the Company wishes to issue and sell to the Purchaser, and the Purchaser wish to acquire from the Company, the warrant identified herein.

WHEREAS, pursuant to those certain Securities Purchase Agreements, dated July 31, 2007, November 1, 2007, and January 15, 2008, by and among the Company, Vicis and the Purchaser named therein (Prior Purchase Agreements), Vicis is the holder of: (1) a Series A Warrant (Series A Warrant) to purchase 50,000,000 shares of the Companys common stock, par value $0.001 per share (the Common Stock), (2) a Series B Warrant (Series B Warrant) to purchase 100,000,000 shares of the Companys Common Stock, (3) a Series C Warrant (Series C Warrant) to purchase 27,777,778 shares of the Companys Common Stock, and (4) a Series D Warrant  to purchase 55,555,556 shares of the Companys Common Stock (Series D Warrant); and (5) a Series E Warrant to purchase 107,142,857 shares of the Companys Common Stock (the Series E Warrant, together with the Series A Warrant, Series B Warrant, Series C Warrant, and Series D Warrant the Existing Vicis Warrants).

WHEREAS, the Existing Vicis Warrants, and certain convertible promissory notes issued by the Company to the Purchaser pursuant to the Prior Purchase Agreements (the Notes) are subject to certain anti-dilution provisions (the Ratchet Provisions) that require the Company to reduce the exercise price of the Warrants and the conversion price of the Notes in the event that the Company is deemed to issue its Common Stock in certain transactions for a price less than the exercise price of the Warrants or the conversion price of the Notes, as the case may be.

WHEREAS, the Purchasers acquisition of warrant hereunder triggers the Ratchet Provisions in the Existing Vicis Warrants, and the Company has agreed to amend the terms of the Existing Vicis Warrants as hereinafter set forth.

WHEREAS, the Purchasers acquisition of warrant hereunder triggers the Ratchet Provisions in the Notes, but the Purchaser has agreed to waive application of the Ratchet Provisions contained in the Notes solely in connection with this transaction as hereinafter set forth.

NOW, THEREFORE, the parties hereto hereby agree as follows:

(b)

At the Closing, the Purchaser shall deliver $3,000,000 (the Purchase Price) by wire transfer to an account designated by the Company.

(c)

The Purchaser acknowledges and agrees that the Company may consummate the sale of additional convertible notes and warrants to other purchasers, on terms substantially similar to the terms of the Prior Purchase Agreements, including without limitation, all pricing terms (provided that, the Company may only sell convertible notes and warrants with conversion and exercise prices, respectively, at or above $.035 per share), which closing shall occur no later than December 15, 2008, for an aggregate purchase price of up to $5,000,000 (the Additional Note and Warrant Financing); provided that the Purchaser shall have a right to exchange the Notes and Warrants acquired by it hereunder for convertible notes and warrants issued in the Additional Note and Warrant Financing, if the Purchaser, in its sole discretion, determines that the Additional Note and Warrant Financing provides terms more favorable to purchasers thereof.  The terms Notes and Warrants shall also be deemed to include the Additional Notes and Additional Warrants. Subject to the terms and conditions of the Prior Purchase Agreements.

Section 1.2

Conversion Shares / Warrant Shares.  The Company hereby represents and warrants to the Purchaser that it has authorized and has reserved and, it hereby covenants to continue to reserve, free of preemptive rights and other similar contractual rights of stockholders, a number of its authorized but unissued shares of Common Stock equal to one hundred percent (100%) of the aggregate number of shares of Common Stock to effect the exercise of the Existing Vicis Warrants and the Series F Warrant as of the Closing Date.  Any shares of Common Stock issuable upon exercise of the Warrants or the Amended Vicis Warrants (as defined below), and such shares when issued, are herein referred to as the Warrant Shares.  The Series F Warrant, the Amended Vicis Warrants, and the Warrant Shares are sometimes collectively referred to herein as the Securities.

Section 1.3

Company Security Agreement.  All of the obligations of the Company under the Transaction Documents shall be secured by a lien on all the personal property and assets of the Company now existing or hereinafter acquired granted pursuant to that certain Security Agreement dated July 31, 2007 between the Company and Vicis, as agent for the secured parties identified therein (Security Agreement), which, except for Permitted Liens (as hereinafter defined), shall be a first lien.  The parties acknowledge and agree that the term Obligations as defined in the Security Agreement includes all of the obligations of the Company to the Purchaser, including without limitation, those obligations of the Company under the Transaction Documents.

Section 1.4

Amendments to Existing Vicis Warrants and Notes.

(a)

For no consideration in addition to the Purchase Price paid by Vicis and in accordance with the anti-dilution provisions of the Existing Vicis Warrants, the Company shall: (i) amend the terms of the Series A Warrant to reduce the initial exercise price of the Series A Warrant to $0.001 and amend and restate the Series A Warrant in the form set forth in Exhibit B-1 (the Amended Series A Warrant); (ii) amend the terms of the Series B Warrant to reduce the initial exercise price of the Series B Warrant to $0.001 and amend and restate the Series B Warrant in the form set forth in Exhibit B-2 (the Amended Series B Warrant); (iii) amend the terms of the Series C Warrant to reduce the initial exercise price of the Series C Warrant to $0.001 and amend and restate the Series C Warrant in the form set forth in Exhibit B-3 (the Amended Series C

(b)

Notwithstanding the fact that as a result of the issuance of the Series F Warrant hereunder, the Ratchet Provisions applicable to the Notes would require the Company to adjust the conversion price of all such Notes to $0.001 per share of Common Stock, the Purchaser agrees to waive, in connection with this transaction only, its right to require the Company to adjust such conversion prices.  The parties agree that (i) the foregoing waiver shall not be deemed to be a waiver of such right  with respect to any future transactions by the Company, (ii) that the foregoing waiver shall not preclude the Purchaser from further enforcement of the Ratchet Provisions in the Notes, and (iii) in the event the Company breaches any of its representations and warranties contained herein as of the date hereof in any material respect, in addition to any other remedies available to Purchaser, the foregoing waiver shall automatically be rescinded and shall no longer be of any force or effect.

(c)

The parties agree that the Amended Vicis Warrants remain Securities as that term is defined in the Prior Purchase Agreements, and that all obligations of the Company under the Prior Purchase Agreements,  and related transaction documents remain in full force and effect as if the Existing Vicis Warrants were not amended hereunder.

Books and Records; Internal Accounting and Disclosure Controls.  The records and documents of the Company accurately reflect in all material respects the information relating to the business of the Company, the location of its assets, and the nature of all transactions giving rise to the obligations or accounts receivable of the Company.

The Companys certifying officers have evaluated the effectiveness of the Companys controls and procedures as of the date prior to the filing date of the most recently filed periodic report under the Exchange Act (such date, the Evaluation Date).  The Company presented in its most recently filed periodic report under the Exchange Act the conclusions of the certifying officers about the effectiveness of the disclosure controls and procedures based on their evaluations as of the Evaluation Date.

Subsequent Financings.

(a)

For a period of one (1) year following the Closing Date, the Company covenants and agrees to promptly notify (in no event later than five (5) days after making or receiving an applicable offer) in writing (a Rights Notice) the Purchaser of the terms and conditions of any proposed private offer or sale to, or exchange with (or other type of distribution to) any third party (a Subsequent Financing), of Common Stock or any debt or equity securities convertible, exercisable or exchangeable into Common Stock; provided, however, prior to delivering a Rights Notice to the Purchaser, the Company shall first deliver to the Purchaser a written notice of the Companys intention to effect a Subsequent Financing (Pre-Notice) within three (3) Trading Days of making or receiving an applicable offer, which Pre-Notice shall ask the Purchaser if it wants to review the details of such financing.  The Purchaser must notify the Company within three (3) Trading Days of receipt of the Pre-Notice that the Purchaser elects to review the details of such financing (Pre-Notice Acceptance).  Upon the Companys receipt of a Pre-Notice Acceptance, and only upon the Companys receipt of a Pre-Notice Acceptance, the Company shall promptly, but no later than two (2) Trading Days after such receipt, deliver a Rights Notice to the Purchaser.  The Rights Notice shall describe, in reasonable detail, the proposed Subsequent Financing, the names and investment amounts of all investors participating in the Subsequent Financing, the proposed closing date of the Subsequent Financing, which shall be within twenty (20) calendar days from the date of the Rights Notice, and all of the terms and conditions thereof and proposed definitive documentation to be entered into in connection therewith.  The Rights Notice shall provide the Purchaser an option (the Rights Option) during the five (5) Trading Days following delivery of the Rights Notice (the Option Period) to inform the Company whether the Purchaser will purchase up to its pro rata portion of all or a portion of the securities being offered in such Subsequent Financing on the same, absolute terms and conditions as contemplated by such Subsequent Financing.  For the avoidance of doubt, the Purchaser may elect to participate in up to 100% of the Subsequent Financing.  If any Purchaser elects not to participate in such Subsequent Financing, the other Purchaser may participate on a pro-rata basis so long as such participation in the aggregate does not exceed the aggregate Purchase Price of all Purchaser hereunder.  For purposes of this Section, all references to pro rata means, for any Purchaser electing to participate in such Subsequent Financing, the percentage obtained by dividing (x) the principal amount of the Notes purchased by the Purchaser at the Closing by (y) the total principal amount of all of the Notes purchased by all of the participating Purchaser at the Closing.  Delivery of any Rights Notice constitutes a representation and warranty by the Company that there are no other material terms and conditions, arrangements, agreements or otherwise except for those disclosed in the Rights Notice, to provide additional compensation to any party participating in any proposed Subsequent Financing, including, but not limited to, additional compensation based on changes in the Purchase Price or any type of reset or adjustment of a purchase or conversion price or to issue additional securities at any time after the closing date of a Subsequent Financing.  If the Company does not receive notice of exercise of the Rights Option from the Purchaser within the Option Period, the Company shall have the right



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.

(b)

For purposes of this Agreement, a Permitted Financing (as defined hereinafter) shall not be considered a Subsequent Financing.  A Permitted Financing shall mean (i) securities issued (other than for cash) in connection with a merger, acquisition, or consolidation, (ii) securities issued pursuant to the conversion or exercise of convertible or exercisable securities issued or outstanding on or prior to the date of this Agreement or issued pursuant to this Agreement (so long as the conversion or exercise price of such securities is not lowered to a price below $.035 per share, and so long as the number of shares of Common Stock underlying such securities is not otherwise increased), (iii) securities issued in connection with bona fide strategic license agreements or other partnering arrangements (whether or not existing as of the date hereof) with a third party (whether or not affiliated with the Company as of the date hereof)  so long as such issuances are not for the sole purpose of raising capital, (iv) Common Stock issued or the issuance or grants of options to purchase Common Stock pursuant to the Companys stock option plans and employee stock purchase plans or non-employee directors stock option or purchase plans, in each case approved by the Companys Board of Directors; provided that, the aggregate amount of Common Stock and Common Stock underlying options issued pursuant to such plans shall not exceed ten percent (10%) of the total amount of Common Stock then issued and outstanding, (v) any warrants issued to the placement agent and its designees for the transactions contemplated by the Purchase Agreement, (vi) securities issued for services provided to the Company by public or investor relations firms and approved by the Companys Board of Directors (vii) securities issued pursuant to the Additional Note and Warrant Financing and securities issuable upon the conversion or exercise of such securities issued pursuant to the Additional Note and Warrant Financing and (viii) the Designee Warrants (as defined in Section 3.21 of the Prior Purchase Agreement dated July 31, 2007).

ARTICLE VCERTIFICATE LEGEND

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) following 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 Company 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 VIINDEMNIFICATION

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 elects 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.

ARTICLE VIIMISCELLANEOUS

as of April __, 2008

[Name and address of Transfer Agent]

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 Exercise 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 Warrant 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 ___________.

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.
