The Company acknowledges and agrees that the representations contained in ARTICLE IV shall not modify, amend or affect such Purchaser’s right to rely on the Company’s representations and warranties contained in this Agreement or any representations and warranties contained in any other Transaction Document or any other document or instrument executed and/or delivered in connection with this Agreement or the consummation of the transaction contemplated hereby.

ARTICLE V.

OTHER AGREEMENTS OF THE PARTIES

5.1 Transfer Restrictions .

(a) The Securities may only be disposed of in compliance with state and federal securities laws. In connection with any transfer of Securities other than pursuant to an effective registration statement under the Securities Act or Rule 144, to the Company or to an Affiliate of a Purchaser or in connection with a pledge as contemplated in Section 5.1(b) , the Company may require the transferor thereof to provide to the Company an opinion of counsel selected by the transferor and reasonably acceptable to the Company, the form and substance of which opinion shall be reasonably satisfactory to

25

the Company, to the effect that such transfer does not require registration of such transferred Securities under the Securities Act.

(b) The Purchasers agree to the imprinting, so long as is required by this Section 5.1 , of a legend on any of the Securities in the following form:

THIS SECURITY HAS NOT BEEN REGISTERED WITH THE SECURITIES AND EXCHANGE COMMISSION OR THE SECURITIES COMMISSION OF ANY STATE IN RELIANCE UPON AN EXEMPTION FROM REGISTRATION UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE “SECURITIES ACT”), AND, ACCORDINGLY, MAY NOT BE OFFERED OR SOLD EXCEPT PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT UNDER THE SECURITIES ACT OR PURSUANT TO AN AVAILABLE EXEMPTION FROM, OR IN A TRANSACTION NOT SUBJECT TO, THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT AND IN ACCORDANCE WITH APPLICABLE STATE SECURITIES LAWS. THIS SECURITY MAY BE PLEDGED IN CONNECTION WITH A BONA FIDE MARGIN ACCOUNT.

(c) Certificates evidencing the Shares and Warrant Shares shall not contain any legend (including the legend set forth in Section 5.1(b) hereof), (i) while a registration statement (including the Registration Statement) covering the resale of such security is effective under the Securities Act, (ii) following any sale of such Shares or Warrant Shares pursuant to Rule 144, (iii) if such Shares or Warrant Shares are eligible for sale under Rule 144, without the requirement for the Company to be in compliance with the current public information required under Rule 144 as to such Shares and Warrant Shares and without volume or manner-of-sale restrictions, 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 Transfer Agent promptly after the Effective Date if required by the Transfer Agent to effect the removal of the legend hereunder. If all or any portion of a Warrant is exercised at a time when there is an effective registration statement to cover the resale of the Warrant Shares, or if such Shares or Warrant Shares may be sold under Rule 144 and the Company is then in compliance with the current public information required under Rule 144, or if the Shares or Warrant Shares may be sold under Rule 144 without the requirement for the Company to be in compliance with the current public information required under Rule 144 as to such Shares or Warrant Shares or if such legend is not otherwise required under applicable requirements of the Securities Act (including judicial interpretations and pronouncements issued by the staff of the Commission) then such Warrant Shares shall be issued free of all legends. The Company agrees that following the Effective Date or at such time as such legend is no longer required under this Section 5.1(c) , it will, no later than three Trading Days following the delivery by a Purchaser to the Company or the Transfer Agent of a certificate representing Shares or Warrant Shares, as the case may be, issued with a restrictive legend (such third Trading Day, the “ Legend Removal Date ”), deliver or cause to be delivered to such Purchaser a certificate representing such shares that is free from all restrictive and other legends. The Company may not make any notation on its records or give instructions to the Transfer Agent that enlarge the

26

restrictions on transfer set forth in this Section 5.1 . Certificates for Securities subject to legend removal hereunder shall be transmitted by the Transfer Agent to the Purchaser by crediting the account of the Purchaser’s prime broker with the Depository Trust Company System as directed by such Purchaser.

5.2 Furnishing of Information; Public Information . Until the earliest of the time that (i) no Purchaser owns Securities or (ii) the Warrants have expired, the Company covenants to maintain the registration of the Common Stock under Section 12(b) of the Exchange Act and to timely file (or obtain extensions in respect thereof and file within the applicable grace period) all reports required to be filed by the Company after the date hereof pursuant to the Exchange Act.

5.3 Integration . The Company shall not sell, offer for sale or solicit offers to buy or otherwise negotiate in respect of any security (as defined in Section 2 of the Securities Act) that would be integrated with the offer or sale of the Securities in a manner that would require the registration under the Securities Act of the sale of the Securities or that would be integrated with the offer or sale of the Securities for purposes of the rules and regulations of Nasdaq such that it would require shareholder approval prior to the closing of such other transaction unless shareholder approval is obtained before the closing of such subsequent transaction.

5.4 Securities Laws Disclosure; Publicity . The Company shall (a) by 9:30 a.m. (New York City time) on the Trading Day immediately following the date hereof, issue a press release disclosing the material terms of the transactions contemplated hereby, and (b) file a Current Report on Form 8-K, including the Transaction Documents as exhibits thereto, with the Commission within the time required by the Exchange Act. The Company and each Purchaser shall consult with each other in issuing any other press releases with respect to the transactions contemplated hereby, and neither the Company nor any Purchaser shall issue any such press release nor otherwise make any such public statement without the prior consent of the Company, with respect to any press release of any Purchaser, or without the prior consent of the Principal Purchasers, with respect to any press release of the Company, which consent shall not unreasonably be withheld or delayed, except if such disclosure is required by law, in which case the disclosing party shall promptly provide the other party with prior notice of such public statement or communication.

5.5 Shareholder Rights Plan . No claim will be made or enforced by the Company or, with the consent of the Company, any other Person, that any Purchaser is an “Acquiring Person” under any control share acquisition, business combination, poison pill (including any distribution under a rights agreement) or similar anti-takeover plan or arrangement in effect or hereafter adopted by the Company, or that any Purchaser could be deemed to trigger the provisions of any such plan or arrangement, by virtue of receiving Securities under the Transaction Documents or under any other agreement between the Company and the Purchasers.

5.6 Use of Proceeds . The Company shall use the net proceeds from the sale of the Securities hereunder for funding operations or for working capital or other general corporate purposes.

5.7 Indemnification of Purchasers . Subject to the provisions of this Section 5.7 , the Company will indemnify and hold each Purchaser and its directors, officers, shareholders,

27

members, partners, employees and agents (and any other Persons with a functionally equivalent role of a Person holding such titles notwithstanding a lack of such title or any other title), each Person who controls such Purchaser (within the meaning of Section 15 of the Securities Act and Section 20 of the Exchange Act), and the directors, officers, shareholders, agents, members, partners or employees (and any other Persons with a functionally equivalent role of a Person holding such titles notwithstanding a lack of such title or any other title) of such controlling persons (each, a “ Purchaser Party ”) harmless from any and all losses, liabilities, obligations, claims, contingencies, damages, costs and expenses, including all judgments, amounts paid in settlements, court costs and reasonable attorneys’ fees and costs of investigation that any such Purchaser Party may suffer or incur as a result of or relating to (a) any breach of any of the representations, warranties, covenants or agreements made by the Company in this Agreement or in the other Transaction Documents or (b) any action instituted against the Purchaser Parties in any capacity, or any of them or their respective Affiliates, by any stockholder of the Company who is not an Affiliate of such Purchaser Parties, with respect to any of the transactions contemplated by the Transaction Documents (unless such action is based upon a breach of such Purchaser Party’s representations, warranties or covenants under the Transaction Documents or any agreements or understandings such Purchaser Parties may have with any such stockholder or any violations by such Purchaser Parties of state or federal securities laws or any conduct by such Purchaser Parties which constitutes fraud, gross negligence, willful misconduct or malfeasance of such Purchaser Party). If any action shall be brought against any Purchaser Party in respect of which indemnity may be sought pursuant to this Agreement, such Purchaser Party shall promptly notify the Company in writing, and the Company shall have the right to assume the defense thereof with counsel of its own choosing reasonably acceptable to the Purchaser Party. Any Purchaser Party shall have the right to employ separate counsel in any such action and participate in the defense thereof, but the fees and expenses of such counsel shall be at the expense of such Purchaser Party except to the extent that (i) the employment thereof has been specifically authorized by the Company in writing, (ii) the Company has failed after a reasonable period of time to assume such defense and to employ counsel or (iii) in such action there is, in the reasonable opinion of counsel, a material conflict on any material issue between the position of the Company and the position of such Purchaser Party, in which case the Company shall be responsible for the reasonable fees and expenses of no more than one such separate counsel. The Company will not be liable to any Purchaser Party under this Agreement (y) for any settlement by a Purchaser Party effected without the Company’s prior written consent, which shall not be unreasonably withheld or delayed; or (z) to the extent, but only to the extent that a loss, claim, damage or liability is attributable to any Purchaser Party’s breach of any of the representations, warranties, covenants or agreements made by such Purchaser Party in this Agreement or in the other Transaction Documents. The indemnification required by this Section 5.7 shall be made by periodic payments of the amount thereof during the course of the investigation or defense, as and when bills are received or are incurred. The indemnity agreements contained herein shall be in addition to any cause of action or similar right of any Purchaser Party against the Company or others and any liabilities the Company may be subject to pursuant to law.

5.8 Reservation of Common Stock . The Company has reserved and the Company shall continue to reserve and keep available at all times, free of preemptive rights, a sufficient number of shares of Common Stock for the purpose of enabling the Company to issue Shares pursuant to this Agreement and Warrant Shares pursuant to any exercise of the Warrants.

28

5.9 Listing of Common Stock . The Company hereby agrees to use reasonable best efforts to maintain the listing or quotation of the Common Stock on the Trading Market on which it is currently listed, and, as promptly as practicable following the Closing, to secure the listing of all of the Shares and Warrant Shares on such Trading Market. The Company further agrees, if the Company applies to have the Common Stock traded on any other Trading Market, it will then include in such application all of the Shares and Warrant Shares, and will take such other action as is necessary to cause all of the Shares and Warrant Shares to be listed or quoted on such other Trading Market as promptly as possible. The Company will then take all action reasonably necessary to continue the listing or quotation and trading of its Common Stock on a Trading Market and will comply in all respects with the Company’s reporting, filing and other obligations under the bylaws or rules of the Trading Market. The Purchasers agree to cooperate in good faith, if necessary, to restructure the transactions contemplated by the Transaction Documents such that they do not contravene the rules and regulations of Nasdaq; provided , however , that such restructuring does not impact the economic interests of the Purchasers contemplated under the Transaction Documents. The Purchasers agree to provide information reasonably requested by the Company to comply with this Section 5.9 and Section 3.24 .

5.10 Equal Treatment of Purchasers . No consideration (including any modification of any Transaction Document) shall be offered or paid to any Person to amend or consent to a waiver or modification of any provision of this Agreement unless the same consideration is also offered to all of the parties to this Agreement. For clarification purposes, this provision constitutes a separate right granted to each Purchaser by the Company and negotiated separately by each Purchaser, and is intended for the Company to treat the Purchasers as a class and shall not in any way be construed as the Purchasers acting in concert or as a group with respect to the purchase, disposition or voting of Securities or otherwise.

5.11 Form D; Blue Sky Filings . The Company agrees to timely file a Form D with respect to the Securities as required under Regulation D and to provide a copy thereof, promptly upon request of any Purchaser. The Company shall take such action as the Company shall reasonably determine is necessary in order to obtain an exemption for, or to qualify the Securities for, sale to the Purchasers at the Closing under applicable securities or “Blue Sky” laws of the states of the United States, and shall provide evidence of such actions promptly upon request of any Purchaser. The Purchaser shall provide any information reasonably requested by the Company to comply with Section 5.11.

5.12 Acknowledgment of Dilution . The Company acknowledges that the issuance of the Securities may result in dilution of the outstanding shares of Common Stock, which dilution may be substantial under certain market conditions. The Company further acknowledges that its obligations under the Transaction Documents, including, without limitation, its obligation to issue the Shares and Warrant Shares pursuant to the Transaction Documents, are unconditional and absolute and not subject to any right of set off, counterclaim, delay or reduction, regardless of the effect of any such dilution or any claim the Company may have against any Purchaser and regardless of the dilutive effect that such issuance may have on the ownership of the other stockholders of the Company.

7.13 Rescission and Withdrawal Right . Notwithstanding anything to the contrary contained in (and without limiting any similar provisions of) any of the other Transaction Documents, whenever any Purchaser exercises a right, election, demand or option under a Transaction Document and the Company does not timely perform its related obligations within the periods therein provided, then such Purchaser may rescind or withdraw, in its sole discretion from time to time upon written notice to the Company, any relevant notice, demand or election in whole or in part without prejudice to its future actions and rights.

7.14 Remedies . In addition to being entitled to exercise all rights provided herein or granted by law, including recovery of damages, each of the Purchasers and the Company will be entitled to specific performance under the Transaction Documents. The parties agree that monetary damages may not be adequate compensation for any loss incurred by reason of any breach of obligations contained in the Transaction Documents and hereby agree to waive and not to assert in any action for specific performance of any such obligation the defense that a remedy at law would be adequate.

7.15 Independent Nature of Purchasers’ Obligations and Rights . The obligations of each Purchaser under any Transaction Document are several and not joint with the obligations of any other Purchaser, and no Purchaser shall be responsible in any way for the performance or non-performance of the obligations of any other Purchaser under any Transaction Document. Nothing contained herein or in any other Transaction Document, and no action taken by any Purchaser pursuant hereof or thereto, shall be deemed to constitute the Purchasers as a partnership, an association, a joint venture or any other kind of entity, or create a presumption that the Purchasers are in any way acting in concert or as a group with respect to such obligations or the transactions contemplated by the Transaction Documents. Each Purchaser shall be entitled

35

to independently protect and enforce its rights, including, without limitation, the rights arising out of this Agreement or out of the other Transaction Documents, and it shall not be necessary for any other Purchaser to be joined as an additional party in any proceeding for such purpose. Each Purchaser has been represented by its own separate legal counsel in its review and negotiation of the Transaction Documents. The Company has elected to provide all Purchasers with the same terms and Transaction Documents for the convenience of the Company and not because it was required or requested to do so by any of the Purchasers.

Vermillion, Inc., a Delaware corporation (the “ Company ”), hereby certifies that, for value received, [ — ], a [ — ], or its registered assign (the “ Holder ”), is entitled to purchase from the Company [•] shares (as adjusted from time to time as provided in Section 12 ) of common stock, par value $0.001 per share, of the Company (the “ Common Stock ”) (each such share, a “ Warrant Share ” and all such shares, the “ Warrant Shares ”), at an exercise price determined pursuant to Section  3 (the “ Exercise Price ”), at any time and from time to time from and after the 90 ^TH day following the date hereof through and including the date that is three (3) years following the date of issuance set forth above (the “ Expiration Date ”), and subject to the following terms and conditions:

1. Purchase Agreement . This Warrant is one of a series of Warrants (collectively, the “ Warrants ”) issued by the Company in connection with that certain Securities Purchase Agreement, entered into on May 8, 2013 (the “ Purchase Agreement ”), by and among the Company and Holder and certain other Purchasers, and is subject to, and the Company and the Holder shall be bound by, all the applicable terms, conditions and provisions of the Purchase Agreement.

2. Definitions. In addition to the terms defined elsewhere in this Warrant, capitalized terms that are not otherwise defined herein shall have the meanings assigned to such terms in the Purchase Agreement.

3. Exercise Price . This Warrant may be exercised for a price per Warrant Share equal to $1.46, subject to adjustment from time to time pursuant to Section 12 .

4. Registration of Warrant . The Company shall register this Warrant, upon records to be maintained by the Company for that purpose (the “ Warrant Register ”), in the name of the record Holder hereof from time to time. The Company may deem and treat the Holder of this Warrant as the absolute owner hereof for the purpose of any exercise hereof or any distribution to the Holder, and for all other purposes, absent actual notice to the contrary.

5. Registration of Transfers . Subject to the Holder’s appropriate compliance with the restrictive legend on this Warrant, the Company shall register the transfer of any portion of this Warrant in the Warrant Register, upon surrender of this Warrant, with the Form of Assignment substantially in the form attached hereto as Attachment B duly completed and signed, to the Company at its address specified herein. Upon any such registration or transfer, a new Warrant to purchase Common Stock, in substantially the form of this Warrant (any such new Warrant, a “ New Warrant ”), evidencing the portion of this Warrant so transferred shall be issued to the transferee and a New Warrant evidencing the remaining portion of this Warrant not so transferred, if any, shall be issued to the transferring Holder. The acceptance of the New Warrant by the transferee thereof shall be deemed the acceptance by such transferee of all of the rights and obligations of a holder of a Warrant.

6. Exercise and Duration of Warrants . This Warrant shall be exercisable by the registered Holder at any time and from time to time on or after the date hereof to and including the Expiration Date. At 6:30 p.m., New York City time, on the Expiration Date, the portion of this Warrant not exercised prior thereto shall be and become void and of no value. The Company may not call or redeem all or any portion of this Warrant without the prior written consent of the Holder.

7. Delivery of Warrant Shares .

(a) To effect conversions hereunder, the Holder shall not be required to physically surrender this Warrant unless the aggregate number of Warrant Shares represented by this Warrant is being exercised. Upon delivery of an Exercise Notice substantially in the form attached hereto as Attachment A (an “ Exercise Notice ”) to the Company at its address for notice determined as set forth herein, and upon payment of the applicable Exercise Price multiplied by the number of Warrant Shares that the Holder intends to purchase hereunder, the Company shall promptly (but in no event later than five (5) trading days after the Date of Exercise (as defined below)) issue and deliver, or cause its transfer agent to issue and deliver, to the Holder a certificate for the Warrant Shares issuable upon such exercise registered in the name of the Holder or its designee. A “ Date of Exercise ” means the date on which the Holder shall have delivered to the Company: (i) an Exercise Notice, appropriately completed and duly signed, and (ii) payment of the Exercise Price (by certified or official bank check, intra-bank account transfer or wire transfer) for the number of Warrant Shares so indicated by the Holder to be purchased.

(b) If by the fifth trading day after a Date of Exercise the Company fails to deliver the required number of Warrant Shares in the manner required pursuant to Section 7(a) , the Holder will have the right to rescind such exercise.

(c) The Company’s obligations to issue and deliver Warrant Shares in accordance with the terms hereof are absolute and unconditional, irrespective of any action or inaction by the Holder to enforce the same, any waiver or consent with respect to any provision hereof, the recovery of any judgment against any Person or any action to enforce the same, or any setoff, counterclaim, recoupment, limitation or termination, or any breach or alleged breach by the Holder or any other Person of any obligation to the Company or any violation or alleged violation of law by the Holder or any other Person, and irrespective of any other circumstance which might otherwise limit such obligation of the Company to the Holder in connection with the issuance of Warrant Shares. Nothing herein shall limit a Holder’s right to pursue any other remedies available to it hereunder, at law or in equity, including a decree of specific performance and/or injunctive relief with respect to the Company’s failure to timely deliver certificates representing shares of Common Stock upon exercise of the Warrant as required pursuant to the terms hereof.

8. Charges, Taxes and Expenses . Issuance and delivery of certificated or uncertificated shares of Common Stock upon exercise of this Warrant shall be made without charge to the Holder for

-2-

any issue or transfer tax, withholding tax, transfer agent fee, or other incidental tax or expense in respect of the issuance of such shares, all of which taxes and expenses shall be paid by the Company; provided , however , that the Company shall not be required to pay any tax which may be payable in respect of any transfer involved in the registration of any certificates for Warrant Shares or Warrants in a name other than that of the Holder. The Holder shall be responsible for all other tax liability that may arise as a result of holding or transferring this Warrant or receiving Warrant Shares upon exercise hereof.

9. Replacement of Warrant . If this Warrant is mutilated, lost, stolen or destroyed, the Company shall issue or cause to be issued in exchange and substitution for and upon cancellation hereof, or in lieu of and substitution for this Warrant, a new Warrant, but only upon receipt of evidence reasonably satisfactory to the Company of such loss, theft or destruction and customary and reasonable indemnity (which shall not include a surety bond), if requested. Applicants for a new warrant under such circumstances shall also comply with such other reasonable regulations and procedures and pay such other reasonable third-party costs as the Company may prescribe. If a new warrant is requested as a result of a mutilation of this Warrant, then the Holder shall deliver this mutilated Warrant to the Company as a condition precedent to the Company’s obligation to issue the new warrant.

10. Reservation of Warrant Shares . The Company covenants that it will at all times reserve and keep available out of the aggregate of its authorized but unissued and otherwise unreserved Common Stock, solely for the purpose of enabling it to issue Warrant Shares upon exercise of this Warrant as herein provided, the number of Warrant Shares which are then issuable and deliverable upon the exercise of this entire Warrant, free from Liens or any other contingent purchase rights of persons other than the Holder (taking into account the adjustments and restrictions of Section 12 ). The Company covenants and warrants that all Warrant Shares so issuable and deliverable shall, upon issuance and the payment of the applicable Exercise Price in accordance with the terms hereof, be duly and validly authorized, issued and fully paid and non-assessable.

11. Notice of Certain Corporate Action . In case the Company shall propose (a) to offer to the holders of its Common Stock rights to subscribe for or to purchase any shares of Common Stock or shares of stock of any class or any other securities, rights or options, or (b) to effect any reclassification of its Common Stock (other than a reclassification involving only the subdivision, or combination, of outstanding shares of Common Stock), or (c) to effect any capital reorganization, or (d) to effect any Fundamental Transaction (as defined below), or (e) to effect the liquidation, dissolution or winding up of the Company or (f) to offer to the holders of its Common Stock the right to have their shares of Common Stock repurchased or redeemed or otherwise acquired by the Company, or (g) to take any other action which would require the adjustment of the Exercise Price and/or the number of Warrant Shares issuable upon exercise of this Warrant, then in each such case (but without limiting the provisions of Section 12), the Company shall give to the Holder, a notice of such proposed action, which shall specify the date on which a record is to be taken for purposes of such dividend, distribution of offer of rights, or the date on which such reclassification, reorganization, Fundamental Transaction, liquidation, dissolution, or winding up is to take place and the date of participation therein by the holders of Common Stock, if any such date is to be fixed and shall also set forth such facts with respect thereto as shall be reasonably necessary to indicate the effect of such action on the Common Stock. Such notice shall be so given at least ten (10) Business Days prior to the record date for determining holders of the Common Stock for purposes of participating in or voting on such action, or at least ten (10) Business Days prior to the date of the taking of such proposed action or the date of participation therein by the holders of Common Stock, whichever shall be the earlier. Such notice shall specify, in the case of any subscription or repurchase rights, the date on which the holders of Common Stock shall be entitled thereto, or the date on which the holders of Common Stock shall be entitled to exchange their Common Stock for securities or other property deliverable upon any reorganization, reclassification, Fundamental Transaction or other action, as the case may be. Such notice shall also state whether the action in question or the record date is subject to the

-3-

effectiveness of a registration statement under the Securities Act or to a favorable vote of security holders, if either is required, and the adjustment in Exercise Price and/or number of Warrant Shares issuable upon exercise of this Warrant as a result of such reorganization, reclassification, Fundamental Transaction or other action, to the extent then determinable. No such notice shall be given if the Company reasonably determines that the giving of such notice would require disclosure of material information which the Company has a bona fide purpose for preserving as confidential or the disclosure of which would not be in the best interests of the Company.

12. Certain Adjustments . The number of Warrant Shares issuable upon exercise of this Warrant is subject to adjustment from time to time as set forth in this Section 12 .

(a) Stock Dividends and Splits . If the Company, at any time while this Warrant is outstanding: (i) pays a stock dividend or otherwise makes a distribution or distributions on shares of its Common Stock or any other equity or equity equivalent securities payable in shares of Common Stock (which, for avoidance of doubt, shall not include any shares of Common Stock issued by the Company upon exercise of any Warrants), (ii) subdivides outstanding shares of Common Stock into a larger number of shares, (iii) combines (including by way of reverse stock split) outstanding shares of Common Stock into a smaller number of shares, or (iv) issues by reclassification of shares of Common Stock any shares of capital stock of the Company; then in each such case (A) the Exercise Price will be adjusted by multiplying the Exercise Price then in effect by a fraction, the numerator of which equals the number of shares of Common Stock outstanding immediately prior to such event (excluding treasury shares, if any), and the denominator of which equals the number of shares of Common Stock outstanding immediately after such event, and (B) the number of Warrant Shares issuable hereunder shall be concurrently adjusted by multiplying such number by the reciprocal of such fraction. Such adjustments will take effect (i) if a record date shall have been fixed for determining the stockholders or security holders, as applicable, of the Company entitled to receive such dividend, distribution or issuance by reclassification, as the case may be, immediately after such record date, (ii) otherwise, immediately after the effective date of such dividend, distribution, subdivision, combination, or issuance by reclassification, as the case may be.

(b) Fundamental Transaction . If, at any time while this Warrant is outstanding, (i) the Company, directly or indirectly, in one or a series of related transactions, (A) effects any merger or consolidation of the Company with or into another Person, (B) effects any sale, lease, license, assignment, transfer, conveyance or other disposition of all or substantially all of its assets, (C) effects any reclassification, reorganization or recapitalization of the Common Stock or any compulsory share exchange pursuant to which the Common Stock is effectively converted into or exchanged for other securities, cash or property (except for issuances by reclassification contemplated by Section 12(a)(iv) ), or (D) consummates a stock or share purchase agreement or other business combination (including a reorganization, recapitalization, spin-off or scheme of arrangement) with another Person or group of Persons whereby such other Person or group acquires more than fifty percent (50%) of the outstanding shares of Common Stock (not including any shares of Common Stock held by the other Person or group making or party to, or associated or affiliated with the other Persons making or party to, such stock or share purchase agreement or other business combination), or (ii) any, direct or indirect, purchase offer, tender offer or exchange offer (whether by the Company or another Person or group of Persons) is completed pursuant to which holders of Common Stock are permitted to sell, tender or exchange their shares for other securities, cash or property (each transaction or series of transactions referred to in clause (i) or (ii) above, a “ Fundamental Transaction ”); then, upon any subsequent exercise of this Warrant, the Holder shall have the right to receive, for each Warrant Share that would have been issuable upon such exercise immediately prior to the occurrence of such Fundamental Transaction, (1) the number of shares of common stock of the successor or acquiring corporation or, if it is the surviving corporation, of the Company, and (2) any additional consideration (the “ Alternate Consideration ”) receivable as a result of such Fundamental Transaction by a holder of the number of shares of Common Stock for which this

-4-

Warrant is exercisable immediately prior to such Fundamental Transaction. For purposes of any such exercise, the determination of the Exercise Price shall be appropriately adjusted to apply to such Alternate Consideration based on the amount and components of Alternate Consideration issuable in respect of one share of Common Stock in such Fundamental Transaction, and the Board shall apportion the Exercise Price among the Alternate Consideration in a reasonable manner reflecting the relative value of any different components of the Alternate Consideration (substituting the most appropriate market-based measure for the Trading Market in determining the daily VWAP from time to time for each component of the Alternate Consideration or, if no market-based measure is reasonably available for any such component, fixing the daily VWAP of such component at the value determined by such apportionment, but subject to further adjustment as provided in this Section 11 ). If holders of Common Stock are given any choice as to the securities, cash or property to be received in a Fundamental Transaction, then the Holder shall be given the same choice as to the Alternate Consideration it receives upon any exercise of this Warrant following such Fundamental Transaction. To the extent necessary to effectuate the foregoing provisions, any successor to the Company or surviving entity in such Fundamental Transaction shall issue to the Holder a new warrant of like tenor to this Warrant but adjusted to be consistent with the foregoing provisions and evidencing the Holder’s right to exercise such warrant for the appropriate number of shares of capital stock and Alternate Consideration, if any, in exchange for this Warrant. The Company shall ensure that the terms of any agreement pursuant to which a Fundamental Transaction is effected shall include terms requiring any such successor or surviving entity to comply with the provisions of this Section 12(b) and ensuring that this Warrant (or any such replacement security) will be similarly adjusted upon any subsequent transaction or series of related transactions analogous to a Fundamental Transaction. “ VWAP ” means, for any date, the price determined by the first of the following clauses that applies: (A) if the Common Stock is then listed or quoted on a trading market, the daily volume weighted average price of the Common Stock for such date (or the nearest preceding date) on the principal trading market on which the Common Stock is then listed or quoted as reported by Bloomberg L.P. (based on a trading day from 9:30 a.m. (New York City time) to 4:02 p.m. (New York City time)), (B) if prices for the Common Stock are then reported in the “Pink Sheets” published by Pink OTC Markets, Inc. (or a similar organization or agency succeeding to its functions of reporting prices), the most recent bid price per share of the Common Stock so reported during trading hours, or (C) in all other cases, the fair market value of a share of Common Stock as determined by an independent appraiser selected in good faith by the Company’s Board of Directors and reasonably acceptable to the Holder, the fees and expenses of which shall be paid by the Company.

(c) Notice of Adjustment . Upon any adjustment of the Exercise Price, and from time to time upon the request of the Holder, the Company shall furnish to the Holder the Exercise Price resulting from such adjustment or otherwise in effect and the number of Warrant Shares then available for purchase under this Warrant, setting forth in reasonable detail the method of calculation and the facts upon which such calculation is based.

13. No Fractional Shares . No fractional shares of Common Stock will be issued in connection with any exercise of this Warrant. In lieu of any fractional shares which would otherwise be issuable, the Company shall pay the Holder an amount of cash equal to the product of such fraction multiplied by the closing price of one share of Common Stock as reported on the principal trading market for the Common Stock on the Date of Exercise.

14. No Impairment . The Company shall not by any action including, without limitation, amending its Certificate of Incorporation, any reorganization, transfer of assets, consolidation, merger, dissolution, issue or sale of securities or any other voluntary action, avoid or seek to avoid the observance or performance of any of the terms of this Warrant, but shall at all times in good faith assist in the carrying out of all such terms and in the taking of all such action, as may be necessary or appropriate to protect the rights of the Holder against impairment. Without limiting the generality of the foregoing, the

-5-

Company shall take all such action as may be necessary or appropriate in order that the Company may validly issue fully paid and nonassessable shares of Common Stock upon the exercise of this Warrant at the then Exercise Price therefor.

15. No Rights as a Stockholder; Notice to Holder . Nothing contained in this Warrant shall be construed as conferring upon the Holder the right to vote or to consent or to receive notice as a stockholder in respect of any meeting of stockholders for the election of directors of the Company or any other matter, or any rights whatsoever as a stockholder of the Company.

16. Warrant Agent . The Company shall serve as warrant agent under this Warrant. Upon thirty (30) days notice to the Holder, the Company may appoint a new warrant agent. Any corporation into which the Company or any new warrant agent may be merged or any corporation resulting from any consolidation to which the Company or any new warrant agent shall be a party or any corporation to which the Company or any new warrant agent transfers substantially all of its corporate trust or stockholders services business shall be a successor warrant agent under this Warrant without any further act. Any such successor warrant agent shall promptly cause notice of its succession as warrant agent to be mailed (by first class mail, postage prepaid) to the Holder at the Holder’s last address as shown on the Warrant Register.

Each Substantial Purchaser shall have five (5) Business Days from the date of receipt of any such notice (except in the case of a bought deal or overnight marketed offering, in which case each Substantial Purchaser shall have one (1) Business Day from the date of receipt of any such notice) to notify the Company in writing that it intends to exercise such purchase rights and as to the amount of New Shares such Substantial Purchaser desires to purchase, up to the maximum amount calculated pursuant to Section 4(a) (the “ Designated Shares ”). Such notice shall constitute a non-binding indication of interest of such Substantial Purchaser to purchase the Designated Shares so specified at the range of prices and other terms set forth in the Company’s notice to it. The failure of a Substantial Purchaser to respond during such five (5) Business Day period (or one (1) Business Day in the case of a bought deal or overnight marketed offering) shall, solely with respect to the Substantial Purchaser who fails to respond, constitute a waiver of the participation rights only in respect of such offering.

Such notice shall constitute the binding agreement of such Substantial Purchaser to purchase the amount of Designated Shares so specified (or a proportionately lesser amount if the amount of New Shares to be offered in such Private Placement is subsequently reduced) upon the price and other terms set forth in the Company’s notice to such Substantial Purchaser. The failure of a Substantial Purchaser to respond during the five (5) Business Day period referred to in the second preceding sentence shall, solely with respect to the Substantial Purchaser who fails to respond, constitute a waiver of the rights in respect of such offering only.

(c) (i) If a Substantial Purchaser exercises its purchase rights provided in Section 4(b)(ii) , the closing of the purchase of the New Shares with respect to which such right has been exercised shall be conditioned on the consummation of the Private Placement giving rise to such purchase rights and shall take place simultaneously with the closing of the Private Placement or on such other date as the Company and such Substantial Purchaser shall agree in writing; provided that the actual amount of Designated Shares to be sold to such Substantial Purchaser pursuant to its exercise of rights hereunder shall be reduced if the aggregate amount of New Shares sold in the Private Placement is reduced and, at the option of such Substantial Purchaser (to be exercised by delivery of written notice to the Company within five (5) Business Days of receipt of notice of such increase), shall be increased if such aggregate amount of New Shares sold in the Private Placement is increased. In connection with its purchase of Designated Shares, each Substantial Purchaser shall execute an instrument in form and substance reasonably satisfactory to the Company containing representations, warranties and agreements of the Substantial Purchaser that are customary for such private placement transactions.

(ii) If a Substantial Purchaser exercises its purchase rights provided in Section 4(b)(i) , the Company shall offer such Substantial Purchaser, if such offering is consummated, the Designated Shares (as adjusted to reflect the actual size of such offering when priced) at the same price as the New Shares are offered to the underwriters or initial purchasers and shall provide written notice of such price to the Substantial Purchaser as soon as practicable prior to such consummation. Contemporaneously with the execution of any underwriting agreement or purchase agreement entered into between the Company and the underwriters or initial purchasers of such offering, such Substantial Purchaser shall enter into an instrument in form and substance reasonably satisfactory to the Company acknowledging such Substantial Purchaser’s binding obligation to purchase the Designated Shares to be acquired by it and containing representations, warranties and agreements of such Substantial Purchaser that are customary in such transactions. Any offers and sales pursuant to this Section 4 in the context of a public offering shall also be conditioned on reasonably acceptable representations and warranties of such Substantial Purchaser regarding its status as the type of offeree to whom a private sale can be made concurrently with a public offering in compliance with applicable securities laws.

(d) In the event a Substantial Purchaser fails to exercise its purchase rights provided in this Section 4 within the applicable five (5) Business Day period or, if so exercised, a Substantial Purchaser does not consummate such purchase within the applicable period, the Company shall thereafter be entitled enter into an agreement to sell the New Shares not purchased pursuant to this Section 4 at the price and on the terms offered to the Substantial Purchasers within 90 days after the conclusion of the applicable period without having to offer such New Shares to the Substantial Purchasers in accordance with this Section 4 .

(e) The Company and each Substantial Purchaser shall cooperate in good faith to facilitate the exercise of the Substantial Purchaser’s rights hereunder, including securing any required approvals or consents, in a manner that does not jeopardize the timing, marketing, pricing or execution of any offering of the Company’s securities.

19

Statement, any preliminary Prospectus or final Prospectus, or any amendment or supplement thereof; (ii) any “Blue Sky” application or other document executed by the Company specifically for that purpose or based upon written information furnished by the Company filed in any state or other jurisdiction in order to qualify any or all of the Registrable Securities under the securities laws thereof (any such application, document or information herein called a “ Blue Sky Application ”); (iii) the omission or alleged omission to state in a Blue Sky Application a material fact required to be stated therein or necessary to make the statements therein not misleading; (iv) any violation by the Company or its agents of any rule or regulation promulgated under the Securities Act applicable to the Company or its agents and relating to action or inaction required of the Company in connection with such registration; or (v) any failure to register or qualify the Registrable Securities included in any such Registration Statement in any state where the Company or its agents has affirmatively undertaken or agreed in writing that the Company will undertake such registration or qualification on a Purchaser’s behalf and will reimburse such Purchaser, and each such officer, director or member 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 such Purchaser or any such controlling person in writing specifically for use in such Registration Statement or Prospectus.

(b) Indemnification by the Purchasers . Each Purchaser agrees, severally but not jointly, to indemnify and hold harmless, to the fullest extent permitted by law, the Company, its directors, officers, employees, stockholders and each person who controls the Company (within the meaning of the Securities Act) against any losses, claims, damages, liabilities and expense (including reasonable attorney fees) resulting from any untrue statement of a material fact or any omission of a material fact required to be stated in the Registration Statement or Prospectus or preliminary Prospectus or amendment or supplement thereto or necessary to make the statements therein not misleading, to the extent, but only to the extent that such untrue statement or omission is contained in any information furnished in writing by such Purchaser to the Company specifically for inclusion in such Registration Statement or Prospectus or amendment or supplement thereto. In no event shall the liability of a Purchaser be greater in amount than the dollar amount of the proceeds (net of all expense paid by such Purchaser in connection with any claim relating to this Section 5 and the amount of any damages such Purchaser has otherwise been required to pay by reason of such untrue statement or omission) received by such Purchaser upon the sale of the Registrable Securities included in the Registration Statement giving rise to such indemnification obligation.

(c) Conduct of Indemnification Proceedings . Any person entitled to indemnification hereunder shall (i) give prompt notice to the indemnifying party of any claim with respect to which it seeks indemnification and (ii) permit such indemnifying party to assume the defense of such claim with counsel reasonably satisfactory to the indemnified party ( provided , however , that such indemnified party shall, at the expense of the indemnifying company, be entitled to counsel of its own choosing to monitor such defense); provided that, subject to the preceding sentence, any person entitled to indemnification hereunder shall have the right to employ separate counsel and to participate in the defense of such claim, but the fees and

20

expenses of such counsel shall be at the expense of such person unless (a) the indemnifying party has agreed to pay such fees or expenses, or (b) the indemnifying party shall have failed to assume the defense of such claim and employ counsel reasonably satisfactory to such person or (c) in the reasonable judgment of any such person, based upon written advice of its counsel, a conflict of interest exists between such person and the indemnifying party with respect to such claims (in which case, if the person notifies the indemnifying party in writing that such person elects to employ separate counsel at the expense of the indemnifying party, the indemnifying party shall not have the right to assume the defense of such claim on behalf of such person); and provided , further , that the failure of any indemnified party to give notice as provided herein shall not relieve the indemnifying party of its obligations hereunder, except to the extent that such failure to give notice shall materially adversely affect the indemnifying party in the defense of any such claim or litigation. It is understood that the indemnifying party shall not, in connection with any proceeding in the same jurisdiction, be liable for fees or expenses of more than one separate firm of attorneys at any time for all such indemnified parties. No indemnifying party will, except with the consent of the indemnified party, consent to entry of any judgment or enter into any settlement that does not include as an unconditional term thereof the giving by the claimant or plaintiff to such indemnified party of a release from all liability in respect of such claim or litigation.

(d) Contribution . If for any reason the indemnification provided for in the preceding paragraphs (a) and (b) is unavailable to an indemnified party or insufficient to hold it harmless, other than as expressly specified therein, then the indemnifying party shall contribute to the amount paid or payable by the indemnified party as a result of such loss, claim, damage or liability in such proportion as is appropriate to reflect the relative fault of the indemnified party and the indemnifying party, as well as any other relevant equitable considerations. No person guilty of fraudulent misrepresentation within the meaning of Section 11(f) of the Securities Act shall be entitled to contribution from any person not guilty of such fraudulent misrepresentation. In no event shall the contribution obligation of a holder of Registrable Securities be greater in amount than the dollar amount of the proceeds (net of all expenses paid by such holder in connection with any claim relating to this Section 5 and the amount of any damages such holder has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission) received by it upon the sale of the Registrable Securities giving rise to such contribution obligation.
