THIS WARRANT AND THE COMMON SHARES ISSUABLE UPON EXERCISE OF THIS WARRANT MAY NOT BE SOLD, OFFERED FOR SALE, PLEDGED OR HYPOTHECATED IN THE ABSENCE OF AN EFFECTIVE REGISTRATION STATEMENT AS TO THIS WARRANT OR THE UNDERLYING SHARES OF COMMON STOCK UNDER SAID ACT AND APPLICABLE STATE SECURITIES LAWS OR AN OPINION OF COUNSEL REASONABLY SATISFACTORY TO IMPLANT SCIENCES CORPORATION THAT SUCH REGISTRATION IS NOT REQUIRED.”

The Purchaser covenants and agrees with the Company as follows:

5.8 Security Interest. Purchaser agrees to terminate its security interest in the assets, as fully described in the Security Agreement between the Company and Purchaser of even date herewith (the “Security Agreement”), upon the Company tendering the final payment in satisfaction of the obligations as defined in the Security Agreement. Purchaser agrees to join with the Company in executing termination statements and other instruments pursuant to the Uniform Commercial Code as enacted and in effect from time to time in the Commonwealth of Massachusetts in form satisfactory to the Company and in executing such other documents or instruments as may be required or deemed necessary by the Company for purposes of terminating the security interest in the collateral.

5.9 Prospectus. Purchaser shall furnish copies of the prospectus in connection with a public sale or disposition of the Common Stock.

5.10 Preferred Stock Certificate. When Purchaser elects to convert shares of Preferred Stock in accordance with Section 8 below, Purchaser shall surrender the Preferred Stock Certificate upon receipt of a credit to the account of the Purchaser’s prime broker through the DWAC system (as defined below), representing the Conversion Shares or upon complete satisfaction of the Preferred Stock.

5.11 Certain Trading Restrictions. Purchaser agrees that, as long as it holds any shares of Preferred Stock, neither it nor any of its Affiliates shall enter into any Short Sales (as defined herein). For purposes of this Section 5.11, a “Short Sale” shall mean a sale of Common Stock by Purchaser that would be required to be marked as a “short sale” by the broker executing the sale pursuant to the provisions of Rules 10a-1(c) and 10a-1(d)(1) under the Exchange Act if such rules applied to the sale (whether or not they in fact apply to the sale), and that is made at a time when immediately after the sale, and giving effect to all other sales by the Purchaser, there would be no equivalent offsetting long position in Common Stock held by

Purchaser. For the purpose of determining under this Section 5.11 whether there is an equivalent offsetting long position in Common Stock held by Purchaser, only those Conversion Shares that are (i) issuable upon conversion of the Preferred Stock for which a conversion notice has been delivered by Purchaser on or prior to a trading day or (ii) issuable as a result of the delivery by the Company of a Repayment Election Notice, as defined in the Certificate of Vote of Directors, shall be deemed to be held long by Purchaser on such trading day.

5.12 Reporting Requirements. Purchaser will timely file with the SEC all reports required to be filed pursuant to the Exchange Act. Purchaser will respond timely, accurately and completely to any inquiry by the SEC, NASD, or any stock exchange upon which the Company maintains a listing, relating to the offering.

6. COVENANTS OF THE COMPANY. The Company covenants and agrees with the Purchaser as follows:

6.1 Stop-Orders. The Company will advise the Purchaser, promptly after it receives notice of issuance by the SEC, any state securities commission or any other regulatory authority of any stop order or of any order preventing or suspending any offering of any securities of the Company, or of the suspension of the qualification of the Common Stock of the Company for offering or sale in any jurisdiction, or the initiation of any proceeding for any such purpose.

6.2 Listing. The Company shall promptly secure the listing of the shares of Common Stock issuable upon conversion of the Preferred Stock and upon the exercise of the Warrant on the Pink Sheets, the NASD OTC Bulletin Board, NASDAQ SmallCap Market, NASDAQ National Market, American Stock Exchange or New York Stock Exchange (the “Principal Market”) upon which shares of Common Stock are then listed (subject to official notice of issuance) and shall maintain such listing so long as any other shares of Common Stock shall be so listed. The Company will maintain the listing of its Common Stock on a Principal Market, and will comply in all material respects with the Company’s reporting, filing and other obligations under the bylaws or rules of the National Association of Securities Dealers (“NASD”) and such exchanges, as applicable. The Company will provide the Purchaser copies of all notices it receives notifying the Company of the threatened and actual delisting of the Common Stock from any Principal Market.

6.3 Market Regulations. The Company shall notify the SEC, NASD and applicable state authorities, in accordance with their requirements, of the transactions contemplated by this Agreement, and shall take all other necessary action and proceedings as may be required and permitted by applicable law, rule and regulation, for the legal and valid issuance of the Securities to Purchaser and promptly provide copies thereof to Purchaser.

6.4 Reporting Requirements. The Company will timely file with the SEC all reports required to be filed pursuant to the Exchange Act and refrain from terminating its status as an issuer required by the Exchange Act to file reports thereunder even if the Exchange Act or the rules or regulations thereunder would permit such termination. In addition, within 20 days after the end of each calendar month, the Company will provide to the Purchaser a monthly cash flow statement, balance sheet and income statement for the immediately preceding month.

Purchaser understands that the provision of the information described herein may constitute material non-public information and such information will only be provided upon the execution by Purchaser of a confidentiality agreement.

6.5 Use of Funds. The Company agrees that it will use the proceeds of the sale of the Preferred Stock and Warrant for the purchase of an Axcelis Ion Implanter and general corporate purposes only, in the ordinary course of its business and consistent with past practice and, without limiting the generality of the foregoing, shall not use such proceeds to make a loan to any employee, officer, director or stockholder of the Company, to repay any loan or other obligation of the Company or to repurchase or pay a dividend on shares of Common Stock or other securities of the Company (in any such case, regardless of whether such loan or payment was authorized by the Company’s Board of Directors prior to the date hereof), other than any such repurchase or payment explicitly required, permitted or contemplated by the terms of this Agreement or the other Related Agreements.

6.6 Access to Facilities. The Company will permit any representatives designated by the Purchaser (or any transferee of the Purchaser), so long as such person holds any Securities upon reasonable notice and during normal business hours, at such person’s expense and accompanied by a representative of the Company, to (a) visit and inspect any of the properties of the Company, (b) examine the corporate and financial records of the Company (unless such examination is not permitted by federal, state or local law or by contract) and make copies thereof or extracts therefrom and (c) discuss the affairs, finances and accounts of any such corporations with the directors, officers and independent accountants of the Company.

6.7 Taxes. The Company will promptly pay and discharge, or cause to be paid and discharged, when due and payable, all lawful taxes, assessments and governmental charges or levies imposed upon the income, profits, property or business of the Company; provided, however, that any such tax, assessment, charge or levy need not be paid if the validity thereof shall currently be contested in good faith by appropriate proceedings and if the Company shall have set aside on its books adequate reserves with respect thereto, and provided, further, that the Company will pay all such taxes, assessments, charges or levies forthwith upon the commencement of proceedings to foreclose any lien which may have attached as security therefor.

6.8 Insurance. The Company will keep its assets which are of an insurable character insured by financially sound and reputable insurers against loss or damage by fire, explosion and other risks customarily insured against by companies in the Company’s line of business, in amounts sufficient to prevent the Company from becoming a co-insurer and not in any event less than 100% of the insurable value of the property insured; and the Company will maintain, with financially sound and reputable insurers, insurance against other hazards and risks and liability to persons and property to the extent and in the manner customary for companies in similar businesses similarly situated and to the extent available on commercially reasonable terms.

6.9 Books and Records. The Company will keep true records and books of account in which full, true and correct entries will be made of all dealings or transactions in relation to its business and affairs in accordance with generally accepted accounting principles

applied on a consistent basis. Purchaser understands that the provision of the information described herein may constitute material non-public information and such information will only be provided upon the execution by Purchaser of a confidentiality agreement, and in accordance with applicable securities law.

6.10 Intellectual Property. The Company shall maintain in full force and effect its corporate existence, rights and franchises and all licenses and other rights to use Intellectual Property owned or possessed by it and reasonably deemed to be necessary to the conduct of its business.

6.11 Confidentiality. The Company agrees that it will not disclose, and will not include in any public announcement, the name of the Purchaser, unless expressly agreed to by the Purchaser or unless and until such disclosure is required by law or applicable regulation, and then only to the extent of such requirement.

6.12 Corporate Existence. The Company shall maintain its corporate existence, and will not liquidate, dissolve or effect a recapitalization, reclassification or reorganization in any form of transaction. In addition, the Company shall not sell all or substantially all of the Company’s assets, except in the event of a merger or consolidation or sale or transfer of all or substantially all of the Company’s assets, where the surviving or successor entity in such transaction (i) assumes the Company’s obligations hereunder and the Related Agreements and (ii) is a publicly traded company whose common stock is quoted or listed on a Principal Market or (iii) simultaneously with the consummation of such transaction irrevocably pays in full all of the obligations due and owing to Purchaser from the Company under this Agreement and/or the Securities.

6.13 Reissuance of Securities. The Company agrees to reissue certificates representing the Securities without the legends set forth in Section 5.7 above at such time as (a) the holder thereof has disposed of such Securities pursuant to an exemption from registration under the Securities Act, or (b) upon resale subject to an effective registration statement after such Securities are registered under the Securities Act. The Company agrees to cooperate with the Purchaser in connection with all resales pursuant to Rule 144(d) and Rule 144(k) and provide legal opinions necessary to allow such resales provided the Company and its counsel receive reasonably requested representations from the selling Purchaser and broker, if any.

6.14 Opinion. On the Closing Date, the Company will deliver to the Purchaser an opinion acceptable to the Purchaser from the Company’s legal counsel in the form annexed hereto as Exhibit C. The Company will provide, at the Company’s expense, such other legal opinions in the future as are reasonably necessary for the conversion of the Preferred Stock and exercise of the Warrants.

6.15 Financing Right of First Refusal. The Company hereby grants the Purchaser a right of first refusal to enter into a financing arrangement with the Company. The Company shall submit a fully executed term sheet setting out the terms, conditions and pricing of any proposed financing (such financing to be negotiated on “arm’s length” terms) to be entered

into by the Company. Purchaser shall have the right, but not the obligation, to offer financing, to the Company on terms no less favorable than those outlined in the previously negotiated term sheet (which such term sheet shall be negotiated in good faith) within five business days of receipt of such proposed term sheet. If the provisions of the Purchaser’s term sheet shall be at least as favorable to the Company, the Company shall enter into the financing arrangement outlined in the Purchaser’s term sheet. If the Purchaser declines to exercise it right of first refusal hereunder, it hereby agrees to enter into such documentation as shall be reasonably requested by Company in order to subordinate its rights hereunder or under the Preferred Stock to the subsequent financier.

7. COVENANTS OF THE COMPANY AND PURCHASER REGARDING INDEMNIFICATION.

7.1 Company Indemnification. The Company agrees to indemnify, hold harmless, reimburse and defend Purchaser, each of Purchaser’s officers, directors, agents, affiliates, control persons, and principal shareholders, against any claim, cost, expense, liability, obligation, loss or damage (including reasonable legal fees) of any nature, incurred by or imposed upon the Purchaser which results, arises out of or is based upon (i) any misrepresentation by Company or breach of any warranty by Company in this Agreement or in any exhibits or schedules attached hereto or any Related Agreement, or (ii) any breach or default in performance by Company of any covenant or undertaking to be performed by Company hereunder, or any other agreement entered into by the Company and Purchaser relating hereto.

7.2 Purchaser’s Indemnification. Purchaser agrees to indemnify, hold harmless, reimburse and defend the Company and each of the Company’s officers, directors, agents, affiliates, control persons and principal shareholders, at all times against any claim, cost, expense, liability, obligation, loss or damage (including reasonable legal fees) of any nature, incurred by or imposed upon the Company which results, arises out of or is based upon (i) any misrepresentation by Purchaser or breach of any warranty by Purchaser in this Agreement or in any exhibits or schedules attached hereto or any Related Agreement; or (ii) any breach or default in performance by Purchaser of any covenant or undertaking to be performed by Purchaser hereunder, or any other agreement entered into by the Company and Purchaser relating hereto.

7.3 Procedures. The procedures and limitations set forth in Section 9.6 shall apply to the indemnifications set forth in Sections 7.1 and 7.2 above.

8. CONVERSION OF PREFERRED STOCK.

8.1 Mechanics of Conversion.

(a) Provided the Purchaser has notified the Company of the Purchaser’s intention to sell the Conversion Shares and the Conversion Shares are included in an effective registration statement or are otherwise exempt from registration when sold: (i) Upon the conversion of the Preferred Stock or part thereof, the Company shall, at its own cost and expense, take all necessary action (including the issuance of an opinion of counsel) to assure that the Company’s transfer agent shall issue the Conversion Shares in the name of the Purchaser (or

its nominee) or such other persons as designated by the Purchaser in accordance with Section 8.1(b) hereof and in such denominations to be specified representing the number of Conversion Shares issuable upon such conversion; and (ii) the Company warrants that no instructions other than these instructions have been or will be given to the transfer agent of the Company’s Common Stock and that after the Effective Date (as hereinafter defined) the Conversion Shares issued will be freely transferable subject to the prospectus delivery requirements of the Securities Act and the provisions of this Agreement, and will not contain a legend restricting the resale or transferability of the Conversion Shares, other than as required by law.

(b) Purchaser will give notice of its decision to exercise its right to convert the Preferred Stock or part thereof by telecopying or otherwise delivering an executed and completed notice of the number of shares to be converted to the Company (the “Notice of Conversion”). The Purchaser will not be required to surrender the Preferred Stock Certificate until the Purchaser receives a credit to the account of the Purchaser’s prime broker through the DWAC system (as defined below), representing the Conversion Shares or until the Preferred Stock has been fully satisfied. Each date on which a Notice of Conversion is telecopied or delivered to the Company in accordance with the provisions hereof shall be deemed a “Conversion Date.” The Company will cause the transfer agent to transmit the Conversion Shares (and a certificate representing the balance of the Preferred Stock not so converted, if requested by Purchaser) to the Purchaser by crediting the account of the Purchaser’s prime broker with the Depository Trust Company (“DTC”) through its Deposit Withdrawal Agent Commission (“DWAC”) system within three (3) business days after receipt by the Company of the Notice of Conversion (the “Delivery Date”).

(c) The Company understands that a delay in the delivery of the Conversion Shares in the form required pursuant to Section 8 hereof beyond the Delivery Date could result in economic loss to the Purchaser. In the event that the Company fails to direct its transfer agent to deliver the Conversion Shares to the Purchaser via the DWAC system within the time frame set forth in Section 8.1(b) above and the Conversion Shares are not delivered to the Purchaser by the Delivery Date through any act or failure to act on the part of the Company, as compensation to the Purchaser for such loss, the Company agrees to pay late payments to the Purchaser for late issuance of the Conversion Shares in the form required pursuant to Section 8 hereof upon conversion of the Preferred Stock in the amount equal to the greater of (i) $500 per business day after the Delivery Date or (ii) the Purchaser’s actual damages from such delayed delivery. The Company shall pay any payments incurred under this Section in immediately available funds upon demand and, in the case of actual damages, accompanied by reasonable documentation of the amount of such damages. Such documentation shall show the number of shares of Common Stock the Purchaser is forced to purchase (in an open market transaction) which the Purchaser anticipated receiving upon such conversion, and shall be calculated as the amount by which (A) the Purchaser’s total purchase price (including customary brokerage commissions, if any) for the shares of Common Stock so purchased exceeds (B) the aggregate Stated Value (as defined in the Certificate of Vote of Directors) and/or dividend amount of the Preferred Stock, for which such Conversion Notice was not timely honored.

(d) Nothing contained herein or in any document referred to herein or delivered in connection herewith shall be deemed to establish or require the payment of a rate of interest or other charges in excess of the maximum permitted by applicable law. In the event that

the rate of interest or dividends required to be paid or other charges hereunder exceed the maximum amount permitted by such law, any payments in excess of such maximum shall be credited against amounts owed by the Company to a Purchaser and thus refunded to the Company.

8.2 Maximum Conversion. The Purchaser shall not be entitled to convert on a Conversion Date that amount of the Preferred Stock in connection with that number of shares of Common Stock which would be in excess of the sum of (i) the number of shares of Common Stock beneficially owned by the Purchaser on a Conversion Date, and (ii) the number of shares of Common Stock issuable upon the conversion of the Preferred Stock with respect to which the determination of this proviso is being made on a Conversion Date, which would result in beneficial ownership by the Purchaser of more than 4.99% of the outstanding shares of Common Stock of the Company on such Conversion Date. Subject to the foregoing, a Purchaser shall not be limited to aggregate conversions of only 4.99%. A Purchaser may void the conversion limitation described in this Section 8.2 upon 75 days prior notice to the Company. Upon an Event of Default under the Preferred Stock, the conversion limitation in this Section 8.2 shall automatically become null and void. Notwithstanding the foregoing, if the Company has elected to make a payment of a Monthly Amount (as defined in the Certificate of Vote of Directors) in shares of Common Stock and such issuance would cause Purchaser’s beneficial ownership to exceed 4.99%, then Purchaser shall be required to sell that number of shares of Common Stock that it beneficially owns in order to permit the Company to make a payment of a Monthly Amount in shares of Common Stock. Beneficial ownership shall be determined in accordance with Section 13(d) of the Exchange Act and Regulation 13d-3 thereunder.

8.3 Optional Redemption. The Company will have the option of redeeming any outstanding Stated Value of the Preferred Stock (“Optional Redemption”) by paying to the Purchaser 130% of such amount, together with accrued but unpaid dividends thereon and any and all other sums due, accrued or payable to the Purchaser arising under this Agreement, Certificate of Vote of Directors or any other document delivered herewith (“Redemption Amount”) outstanding on the day notice of redemption (“Notice of Redemption”) is delivered to a Purchaser (“Redemption Date”). A Notice of Redemption may not be given in connection with any portion of Preferred Stock for which a Notice of Conversion has been given by the Purchaser at any time before receipt of a Notice of Redemption. The Redemption Amount must be paid in immediately available funds to the Purchaser no later than the seventh (7th) business day after the Redemption Date (“Optional Redemption Payment Date”). In the event the Company fails to pay the Redemption Amount by the Optional Redemption Payment Date, then the Redemption Notice will be null and void. A Notice of Redemption may be given by the Company, provided no Event of Default as described in the Certificate of Vote of Directors shall have occurred or be continuing.

9. REGISTRATION RIGHTS.

9.1 Registration Rights Granted. The Company hereby grants the following registration rights to holders of the securities purchased hereby.

(a) The Company shall use its reasonable commercial efforts to file a Form S-3 registration statement (or such other form that it is eligible to use) in order to register

the Securities (the “Registrable Securities”) for resale and distribution under the Securities Act with the SEC by January , 2004 (the “Filing Date”), and use its reasonable commercial efforts to cause such registration statement to be declared effective within 90 days of the Filing Date (the “Effective Date”). The Company will register (a sufficient number of shares of Common Stock to cover full conversion of the Preferred Stock and the Warrant) shares of Common Stock in the aforedescribed registration statement. The Registrable Securities shall be reserved and set aside exclusively for the benefit of the Purchaser and the holders of the Warrant, as the case may be, and not issued, employed or reserved for anyone other than the Purchaser and the holders of the Warrant. If the closing price of the Common Stock is less than $3.00 per share for five (5) consecutive trading days prior to the Effective Date, then such registration statement will be promptly amended or additional registration statements will be promptly filed by the Company as necessary to register additional shares of Common Stock of the Company to allow the public resale of all Common Stock included in and issuable by virtue of the Registrable Securities. No securities of the Company other than the Registrable Securities will be included in the registration statement described in this Section 9.1(a).

9.2 Registration Procedures. If and whenever the Company is required by the provisions hereof to effect the registration of any shares of Registrable Securities under the Securities Act, the Company will, as expeditiously as possible:

(a) prepare and file with the SEC a registration statement with respect to such securities and use its best efforts to cause such registration statement to become and remain effective for the period of the distribution contemplated thereby (determined as herein provided), and promptly provide to the holders of Registrable Securities copies of all filings and SEC letters of comment;

(b) prepare and file with the SEC such amendments and supplements to such registration statement and the prospectus used in connection therewith as may be necessary to keep such registration statement effective until the later of: (i) six months after the latest exercise period of the Warrants; or (ii) four years after the Closing Date, and comply with the provisions of the Securities Act with respect to the disposition of all of the Registrable Securities covered by such registration statement in accordance with the Seller’s intended method of disposition set forth in such registration statement for such period;

(c) furnish to the Seller, and to each underwriter if any, such number of copies of the registration statement and the prospectus included therein (including each preliminary prospectus) as such persons reasonably may request to facilitate the public sale or their disposition of the securities covered by such registration statement;

(d) use its best efforts to register or qualify the Seller’s Registrable Securities covered by such registration statement under the securities or “blue sky” laws of such jurisdictions as the Seller and in the case of an underwritten public offering, the managing underwriter shall reasonably request, provided, however, that the Company shall not for any such purpose be required to qualify generally to transact business as a foreign corporation in any jurisdiction where it is not so qualified or to consent to general service of process in any such jurisdiction;

(e) list the Registrable Securities covered by such registration statement with any securities exchange on which the Common Stock of the Company is then listed;

(f) immediately notify the Seller and each underwriter under such registration statement at any time when a prospectus relating thereto is required to be delivered under the Securities Act, of the happening of any event of which the Company has knowledge as a result of which the prospectus contained in such registration statement, as then in effect, includes an untrue statement of a material fact or omits to state a material fact required to be stated therein or necessary to make the statements therein not misleading in light of the circumstances then existing; and

(g) make available for inspection by the Seller, any underwriter participating in any distribution pursuant to such registration statement, and any attorney, accountant or other agent retained by the Seller or underwriter, all publicly available, non-confidential financial and other records, pertinent corporate documents and properties of the Company, and cause the Company’s officers, directors and employees to supply all publicly available, non-confidential information reasonably requested by the seller, underwriter, attorney, accountant or agent in connection with such registration statement.

9.3 Provision of Documents. In connection with each registration hereunder, the Purchaser will furnish to the Company in writing such information and representation letters with respect to itself and the proposed distribution by it as reasonably shall be necessary in order to assure compliance with federal and applicable state securities laws.

9.4 Non-Registration Events. If (i) the registration statement on Form S-3 or such other form as described in Section 9.1(a) is not filed on or before the Filing Date or not declared effective on or before the sooner of the Effective Date, or within three business days of receipt by the Company of a communication from the SEC that the registration statement described in Section 9.1(a) will not be reviewed, or (iii) if the registration statement described in Section 9.1(a) is filed and declared effective but shall thereafter cease to be effective (without being succeeded immediately by an additional registration statement filed and declared effective) for a period of time which shall exceed 30 days in the aggregate per year but not more than 20 consecutive calendar days (defined as a period of 365 days commencing on the date the Registration Statement is declared effective) (each such event referred to in this Section 9.4 is referred to herein as a “Non-Registration Event”), then, for so long as such Non-Registration Event shall continue, the Company shall pay in cash as Liquidated Damages to each holder of any Registrable Securities an amount equal to one percent (1%) per month (prorated accordingly for parts thereof) during the pendency of such Non-Registration Event of the Stated Value of the Preferred Stock issued in connection with the Offering, whether or not converted, then owned of record by such holder or issuable as of or subsequent to the occurrence of such Non-Registration Event, but no in event more than 130% the unpaid Stated Value of the Preferred Stock. Payments to be made pursuant to this Section shall be due and payable immediately upon demand in immediately available funds. It shall be deemed a Non-Registration Event to the extent that all the Common Stock included in the Registrable Securities and underlying the Securities is not included in an effective registration statement as of and after the Effective Date at the conversion prices in effect from and after the Effective Date. Failure by the Company to

pay the Liquidated Damages as and when due shall be deemed an Event of Default for the purposes of this Section 9.4

9.5 Expenses. All expenses incurred by the Company in complying with Section 9, including, without limitation, all registration and filing fees, printing expenses, fees and disbursements of counsel and independent public accountants for the Company, fees and expenses (including reasonable counsel fees) incurred in connection with complying with state securities or “blue sky” laws, fees of the NASD, transfer taxes, fees of transfer agents and registrars, fees of, and up to $2,500 in disbursements incurred by, one counsel for the Seller, and costs of insurance are called “Registration Expenses”. All underwriting discounts and selling commissions applicable to the sale of Registrable Securities, including any fees and disbursements of any special counsel to the Seller beyond those included in Registration Expenses, are called “Selling Expenses.”

The Company will pay all Registration Expenses in connection with the registration statement under Section 9. All Selling Expenses in connection with each registration statement under Section 9 shall be borne by the Seller and may be apportioned among the Sellers in proportion to the number of shares sold by the Seller relative to the number of shares sold under such registration statement or as all Sellers thereunder may agree.

9.6 Indemnification and Contribution.

(a) In the event of a registration of any Registrable Securities under the Securities Act pursuant to Section 9, the Company will indemnify and hold harmless each Seller, each officer of each Seller, each director of each Seller, each underwriter of such Registrable Securities thereunder and each other person, if any, who controls any such Seller or underwriter within the meaning of the Securities Act, against any losses, claims, damages or liabilities, joint or several, to which the Seller, or such underwriter or controlling person may become subject under the Securities Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon any untrue statement or alleged untrue statement of any material fact contained in any registration statement under which such Registrable Securities was registered under the Securities Act pursuant to Section 9, any final prospectus contained therein, or any amendment or supplement thereof, or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, and will reimburse the Seller, each such underwriter and each such controlling person for any legal or other expenses reasonably incurred by them in connection with investigating or defending any such loss, claim, damage, liability or action; provided, however, that the Company will not be liable in any such case if and to the extent that any such loss, claim, damage or liability arises out of or is based upon an untrue statement or alleged untrue statement or omission or alleged omission so made in conformity with information furnished by any such Seller, the underwriter or any such controlling person in writing specifically for use in such registration statement or prospectus.

(b) In the event of a registration of any of the Registrable Securities under the Securities Act pursuant to Section 9, the Seller will indemnify and hold harmless the Company, and each person, if any, who controls the Company within the meaning of the Securities Act, each officer of the Company who signs the registration statement and each

director of the Company, against all losses, claims, damages or liabilities, joint or several, to which the Company or such officer or director may become subject under the Securities Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon any untrue statement or alleged untrue statement of any material fact contained in the registration statement under which such Registrable Securities were registered under the Securities Act pursuant to Section 9, any final prospectus contained therein, or any amendment or supplement thereof, or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, and will reimburse the Company and each such officer or director for any legal or other expenses reasonably incurred by them in connection with investigating or defending any such loss, claim, damage, liability or action, provided, however, that the Seller will be liable hereunder in any such case if and only to the extent that any such loss, claim, damage or liability arises out of or is based upon an untrue statement or alleged untrue statement or omission or alleged omission made in reliance upon and in conformity with information pertaining to such Seller, as such, furnished in writing to the Company by such Seller specifically for use in such registration statement or prospectus, and provided, further, however, that the liability of the Seller hereunder shall be limited to the proportion of any such loss, claim, damage, liability or expense which is equal to the proportion that the public offering price of the Registrable Securities sold by the Seller under such registration statement bears to the total public offering price of all securities sold thereunder, but not in any event to exceed the net proceeds received by the Seller from the sale of Registrable Securities covered by such registration statement.

(c) Promptly after receipt by an indemnified party hereunder of notice of the commencement of any action, such indemnified party shall, if a claim in respect thereof is to be made against the indemnifying party hereunder, notify the indemnifying party in writing thereof, but the omission so to notify the indemnifying party shall not relieve it from any liability which it may have to such indemnified party other than under this Section 9.6(c) and shall only relieve it from any liability which it may have to such indemnified party under this Section 9.6(c) if and to the extent the indemnifying party is prejudiced by such omission. In case any such action shall be brought against any indemnified party and it shall notify the indemnifying party of the commencement thereof, the indemnifying party shall be entitled to participate in and, to the extent it shall wish, to assume and undertake the defense thereof with counsel reasonably satisfactory to such indemnified party, and, after notice from the indemnifying party to such indemnified party of its election so to assume and undertake the defense thereof, the indemnifying party shall not be liable to such indemnified party under this Section 9.6(c) for any legal expenses subsequently incurred by such indemnified party in connection with the defense thereof other than reasonable costs of investigation and of liaison with counsel so selected, provided, however, that, if the defendants in any such action include both the indemnified party and the indemnifying party and the indemnified party shall have reasonably concluded that there may be reasonable defenses available to it which are different from or additional to those available to the indemnifying party or if the interests of the indemnified party reasonably may be deemed to conflict with the interests of the indemnifying party, the indemnified parties shall have the right to select one separate counsel and to assume such legal defenses and otherwise to participate in the defense of such action, with the reasonable expenses and fees of such separate counsel and other expenses related to such participation to be reimbursed by the indemnifying party as incurred.

(d) In order to provide for just and equitable contribution in the event of joint liability under the Securities Act in any case in which either (i) the Seller, or any controlling person of the Seller, makes a claim for indemnification pursuant to this Section 9.6 but it is judicially determined (by the entry of a final judgment or decree by a court of competent jurisdiction and the expiration of time to appeal or the denial of the last right of appeal) that such indemnification may not be enforced in such case notwithstanding the fact that this Section 9.6 provides for indemnification in such case, or (ii) contribution under the Securities Act may be required on the part of the Seller or controlling person of the Seller in circumstances for which indemnification is provided under this Section 9.6; then, and in each such case, the Company and the Seller will contribute to the aggregate losses, claims, damages or liabilities to which they may be subject (after contribution from others) in such proportion so that the Seller is responsible only for the portion represented by the percentage that the public offering price of its securities offered by the registration statement bears to the public offering price of all securities offered by such registration statement, provided, however, that, in any such case, (A) the Seller will not be required to contribute any amount in excess of the public offering price of all such securities offered by it pursuant to such registration statement; and (B) no person or entity guilty of fraudulent misrepresentation (within the meaning of Section 10(f) of the Securities Act) will be entitled to contribution from any person or entity who was not guilty of such fraudulent misrepresentation.

10. OFFERING RESTRICTIONS. Except as previously disclosed in the SEC Reports or stock or stock options granted to employees or directors of the Company; or equity or debt issued in connection with an acquisition of a business or assets by the Company; or the issuance by the Company of stock in connection with the establishment of a joint venture partnership or licensing arrangement (these exceptions hereinafter referred to as the “Excepted Issuances”), the Company will not issue any securities with a floorless variable/floating conversion feature, otherwise known as a “floorless convertible security” which are or could be (by conversion or registration) free-trading securities prior to the repayment in full or conversion in full of the Preferred Stock.

11. SECURITY INTEREST. As a condition of Closing, the Company will grant to the Purchaser a security interest in its assets pursuant to a Security Agreement. The Company will also execute all such documents reasonably necessary to memorialize and further protect the security interest described above.

12. MISCELLANEOUS.

12.1 Governing Law. This Agreement shall be governed by and construed in accordance with the laws of the State of New York, without regard to principles of conflicts of laws. Any action brought by either party against the other concerning the transactions contemplated by this Agreement shall be brought only in the state courts of New York or in the federal courts located in the state of New York; provided, however that the Purchaser may choose to waive this provision and bring an action outside the state of New York. Both parties and the individuals executing this Agreement and other agreements on behalf of the Company agree to submit to the jurisdiction of such courts and waive trial by jury. The prevailing party shall be entitled to recover from the other party its reasonable attorney’s fees and costs. In the event that any provision of this Agreement or any other agreement delivered in connection

herewith is invalid or unenforceable under any applicable statute or rule of law, then such provision shall be deemed inoperative to the extent that it may conflict therewith and shall be deemed modified to conform with such statute or rule of law. Any such provision which may prove invalid or unenforceable under any law shall not affect the validity or enforceability of any other provision of any agreement.

12.2 Survival. The representations, warranties, covenants and agreements made herein shall survive any investigation made by the Purchaser and the closing of the transactions contemplated hereby. All statements as to factual matters contained in any certificate or other instrument delivered by or on behalf of the Company pursuant hereto in connection with the transactions contemplated hereby shall be deemed to be representations and warranties by the Company hereunder solely as of the date of such certificate or instrument.

12.3 Successors and Assigns. Except as otherwise expressly provided herein, the provisions hereof shall inure to the benefit of, and be binding upon, the successors, assigns, heirs, executors and administrators of the parties hereto and shall inure to the benefit of and be enforceable by each person who shall be a holder of the Securities from time to time.

12.4 Entire Agreement. This Agreement, the exhibits and schedules hereto, the Related Agreements and the other documents delivered pursuant hereto constitute the full and entire understanding and agreement between the parties with regard to the subjects hereof and no party shall be liable or bound to any other in any manner by any representations, warranties, covenants and agreements except as specifically set forth herein and therein.

12.5 Severability. In case any provision of the Agreement shall be invalid, illegal or unenforceable, the validity, legality and enforceability of the remaining provisions shall not in any way be affected or impaired thereby.

12.6 Amendment and Waiver.

(b) The obligations of the Company and the rights of the holders of the Securities under the Agreement may be waived only with the written consent of such holders of Securities. The rights of the holder of Preferred Stock may be waived only with the written consent of such holder.

12.7 Delays or Omissions. It is agreed that no delay or omission to exercise any right, power or remedy accruing to any party, upon any breach, default or noncompliance by another party under this Agreement or the Related Agreements, shall impair any such right, power or remedy, nor shall it be construed to be a waiver of any such breach, default or noncompliance, or any acquiescence therein, or of or in any similar breach, default or noncompliance thereafter occurring. It is further agreed that any waiver, permit, consent or approval of any kind or character on the Purchaser’s part of any breach, default or noncompliance under this Agreement, the Preferred Stock or the Related Agreements or any waiver on such party’s part of any provisions or conditions of the Agreement, the Certificate of Vote of Directors or the Related Agreements must be in writing and shall be effective only to the

extent specifically set forth in such writing. All remedies, either under this Agreement, the Preferred Stock or the Related Agreements, by law or otherwise afforded to any party, shall be cumulative and not alternative.

All notices required or permitted hereunder shall be in writing and shall be deemed effectively given: (a) upon personal delivery to the party to be notified, (b) when sent by confirmed telex or facsimile if sent during normal business hours of the recipient, if not, then on the next business day, (c) five days after having been sent by registered or certified mail, return receipt requested, postage prepaid, or (d) one day after deposit with a nationally recognized overnight courier, specifying next day delivery, with written verification of receipt.
