Asset Purchase Agreement dated January 10, 2008 with Indigoleaf Associates Ltd. and Dr. Amnon Gonenne

The Vendor agrees to sell and transfer to Pubco at the Closing (as defined below) all the Intellectual Property Assets free and clear of all liens, charges, claims or other encumbrances, on the terms and subject to the conditions set out in this Agreement (the "Sale Transactions").

At the Closing, in full and final consideration of the transfer of the Intellectual Property Assets to Pubco, Pubco shall issue to the Vendor 25,638,400 common shares in the

capital of Pubco (the "Vendor Shares"), which shares shall be issued as fully-paid and non-assessable.

At the Closing, in consideration of the services (the "Executive Services") to be provided by the Executive, to Pubco after the Closing (as provided in the employment agreement (the "CEO Employment Agreement") to be entered into by Pubco and the Executive), Pubco shall issue to the Executive 6,409,600 common shares in the capital of Pubco (the "Executive Shares"; the Executive Shares and the Vendor Shares collectively, the "Transaction Shares"), which shares when issued shall be issued as fully-paid and non- assessable. Notwithstanding the foregoing, the Executive agrees and acknowledges that its entitlement and title to 75% of the Executive Shares (i.e. 4,807,200 shares; the "Vesting Shares"), which shares shall be held in escrow by the Escrow Agent (as defined below), shall be earned in three 6-month intervals (each an "Interval") from the Closing (i.e. 1,602,400 shares at the end of each Interval) and the Executive shall only be entitled to the aggregate amount of the Vesting Shares if he continues to be retained by Pubco to provide the Executive Services for a continuous period of 18 months from the Closing (the "Employment Term"). For further certainty, and without limiting the generality of the foregoing, if the CEO Employment Agreement is terminated before the end of the Employment Term, then the number of Vesting Shares that the Executive shall be entitled to, shall be a pro rata amount, calculated as a percentage of the completed amount of the Employment Term from the Closing to the end of the most recently completed Interval. Notwithstanding the foregoing, the Executive hereby acknowledges and agrees that, in the event that any of the Vesting Shares shall not be vested to the Executive pursuant to the terms hereof, the Escrow Agent is hereby authorized and directed to deliver such shares to the registrar and transfer agent of Pubco for cancellation and return to treasury.

Notwithstanding the foregoing, if, prior to the 18-month anniversary of the Closing: (a) Pubco terminates the services of the Executive without "cause" (defined as: (i) the continued failure by the Executive to substantially perform his duties according to the terms of the CEO Employment Agreement (other than any such failure resulting from the disability (as defined below) of the Executive) after Pubco shall have given the Executive reasonable notice in writing of such failure and a reasonable opportunity, of not less than 30 days, to correct same, (ii) the conviction of the Executive for embezzlement, theft, fraud or other criminal offence, (iii) the breach by the Executive of a fiduciary duty owed to Pubco, or (iv) the breach by the Executive of any confidentiality or non-competition agreement of undertaking of the Executive; or (b) in the event of a "change of control" of Pubco (defined as the amalgamation, arrangement, merger, consolidation or other combination of Pubco with another entity pursuant to which the shareholders of Pubco immediately before such amalgamation, agreement, merger, consolidation or other combination do not own securities of the successor or continuing entity which would entitle them to cast more than 50% of the votes attaching to all common shares in the capital of the successor or continuing entity immediately thereafter), then all the Vesting Shares not yet vested shall vest immediately. Furthermore, and notwithstanding the foregoing, if, prior to the 18-month anniversary of the Closing, the Executive is unable to provide the Executive Services, by reason of his death or "disability" (defined as the inability of the Executive to perform the material and substantial duties in respect of the Executive Services on a full-time basis for a period of four consecutive weeks during the

The Transaction Shares shall in aggregate represent 54% of the fully diluted capital stock of Pubco immediately following the Closing, (but expressly excluding the common shares issuable upon the exercise of the warrants to be issued in connection with the Financing (as defined below).

Prior to the Closing, Pubco shall effect a 20-for-1 forward split of its authorized and issued and outstanding common shares (the "Forward Split"), such that the fully diluted capitalization of Pubco after: (a) the Forward Split; (b) issuance of the Transaction Shares; and (b) the issuance of units (consisting of one common share in the capital of Pubco and two warrants, each exercisable for one common share in the capital of Pubco) in connection with the Financing shall be as follows:

Each of the Vendor and the Executive acknowledges that the Transaction Shares shall be restricted as to sale under United States securities laws and rules, and shall carry a restrictive legend indicating such restrictions. Additionally, each of the Vendor and the Executive agrees not to sell, pledge or option any Transaction Shares for a period of two years from the Closing; provided, however, that this limitation shall expire upon and shall not apply to, an event of a "change of control" of Pubco (as defined above) (the "No Sale Limitation").

All share certificates for the Vendor Shares shall be issued in the name of Vendor and all share certificates for the Executive Shares shall be issued in the name of the Executive. Notwithstanding any other provision hereof, share certificates representing the aggregate amount of both the Vendor Shares and the Executive Shares shall be held in escrow pursuant to the provisions of Part 3 hereof by a mutually agreed third party escrow agent (the "Escrow Agent").

To ensure compliance with the No Sale Limitation and the vesting requirements under Section 3 hereof, all of the Transaction Shares shall be held in escrow by the Escrow Agent pursuant to the terms hereof for a period of two years from the Closing (the "No Sale Escrow Period"), and may not be sold, pledged or optioned during that period. Subject to Section 9 hereof, upon the expiration of the No Sale Escrow Period, the Escrow Agreement shall release the share certificates representing all the Executive

Shares (then in escrow and vested) to the Executive and 30% of the Vendor Shares to the Vendor without the need for Pubco’s prior consent.

Notwithstanding any other provision hereof, with respect to the Vendor Shares, to secure the IP Representations (as defined below) of the Vendor, 70% of the Vendor Shares (the "IP Escrow Shares") shall be held in escrow by the Escrow Agent pursuant to the terms hereof for a period of three years from the Closing (the "IP Escrow Period"). For further clarity, upon the second anniversary of the Closing, subject to Section 3 hereof, all the Executive Shares and 30% of the Vendor Shares shall be released by the Escrow Agent to the Executive and the Vendor, respectively, regardless of any claim on the IP Representations, and the remaining Vendor Shares shall be released in accordance with the escrow provisions set out below.

Each of Pubco and the Vendor agrees and acknowledges that the IP Escrow Shares held by the Escrow Agent may not be sold, pledged or optioned during the IP Escrow Period and are to be held in escrow for the sole and exclusive security of Pubco in respect of any breach of the IP Representations. For further certainty, each of Pubco and the Vendor agrees and acknowledges that other than a claim in respect of the IP Escrow Shares as set out below, Pubco shall have no demand, right, cause of action or remedy against the Vendor or its permitted transferees, including its shareholders, beneficial owners, directors or other affiliates or their assets for the breach of any of the Vendor's representations or warranties contained herein Agreement or in any of the closing documents delivered by the Vendor in respect of the Sale Transactions.

While held in escrow, the Vendor and the Executive shall have voting rights for their Transaction Shares (but expressly including the Vesting Shares, even if not yet vested), and distributions of stock of Pubco made in respect to their respective Transaction Shares shall be distributed to the Escrow Agent to be held pursuant to the same terms and conditions the Escrow Agent holds the Transaction Shares on account of the Vendor and the Executive, respectively. All other distributions made in respect to Transaction Shares shall be distributed directly to the Vendor and the Executive, for their own account.

During the IP Escrow Period, if any third party files a claim against Pubco, or threatens in writing to sue Pubco (a "Third Party Claim"), alleging facts that evidence a breach of the IP Representations of the Vendor, Pubco shall be entitled to make a claim against the IP Escrow Shares, and recover damages from such Shares, as follows:

Promptly after becoming aware of a Third Party Claim, and prior to expiration of the IP Escrow Period, Pubco shall notify the Vendor and/or Vendor shall notify Pubco and the Escrow Agent, in writing (an "Escrow Claim Notice"), specifying in reasonable detail the alleged breach of the IP Representations and the anticipated amount of damages resulting from such alleged breach plus anticipated reasonable costs of defence of such claim (the "Claimed Amount");

If the Vendor does not, within 20 business days after receipt of an Escrow Claim Notice (the "Contest Period") contest such Escrow Claim Notice by notice in writing (the "Contention") to the Escrow Agent with a copy to Pubco, then within five business days thereafter, the Escrow Agent shall transfer to Pubco such number of IP Escrow Shares EQUAL TO: TWICE the Claimed Amount

DIVIDED by the average closing share price of the common shares of Pubco, as quoted on the Market or other exchange on which such shares are traded during the period of consecutive 21 trading days preceding the day of the delivery of the Escrow Notice (the "Average Price");

If the Vendor delivers to the Escrow Agent the Contention within the Contest Period, the Escrow Agent shall hold such number of IP Escrow Shares EQUAL TO: the Claimed Amount DIVIDED by the Average Price, and shall release such number of IP Escrow Shares (to the Vendor or Pubco, as applicable) only pursuant to either: (i) a written notice signed by both Pubco and the Vendor (the "Resolution Notice"); or (ii) a final arbitration award, issued in accordance with the arbitration provisions below and instructing the Escrow Agent how to release such shares (an "Award Notice"). Within five business days after receipt of such Resolution Notice or Award Notice, as applicable, the Escrow Agent shall release to Pubco and/or Vendor the IP Escrow Shares held back by the Escrow Agent, as instructed;

Within three business days after the expiration of the IP Escrow Period, the Escrow Agent shall release to the Vendor all IP Escrow Shares then held by the Escrow Agent. Notwithstanding the foregoing, in the event that certain IP Escrow Shares are subject at such time to a pending but unresolved IP Escrow Notice, as set forth in Section 12(c) hereof, and the Claimed Amount is quantified (as a specified dollar amount), then such number IP Escrow Shares as EQUALS twice the number that would result from the calculation as set out in Section 12(b) hereof (provided, however, that the determination of the average trading price shall commence at least three days after disclosure to the public of the pending claim) shall continue to be held in escrow until receipt by the Escrow Agent of a Resolution Notice or an Award Notice with respect thereto, as detailed in Section 12(c) hereof. If the Claimed Amount is not quantified, then all the IP Escrow Shares shall continue to be held in escrow until resolution as set forth in Section 12(c) hereof;

Notwithstanding anything to the contrary herein: (i) no Escrow Claim Notice shall be given if the Claimed Amount (in aggregate with previous claims) does not exceed $20,000; and (ii) the recourse of Pubco to the IP Escrow Shares shall be its sole and exclusive remedy against the Vendor or the Executive in connection with this Agreement; and

Further, Pubco shall allow Vendor to conduct and control the defence of any Third Party Claim, including the disposition of such Claim (including all decisions relative to litigation, appeal, and settlement), with attorneys of Vendor's choice. Pubco shall cooperate fully with the Vendor in such defence, and shall not admit any fact or liability, discuss or reach a settlement, or take any other action affecting the defence of such Third Party Claim in the absence of Vendor's prior written consent.

Pubco shall arrange a private placement with certain investors (the "Financiers") in the

amount of $1,300,000 (the "Financing") of units (at the price of $1.00 per unit) consisting of one common share of Pubco (the "Financing Shares") and two whole warrants (with one warrant entitling the holder to purchase one common share of Pubco at $1.25 per share for a period of one year from the Closing and one warrant entitling the holder to purchase one common share of Pubco at $1.25 per share for a period of two years from the Closing) (the "Financing Warrants").

The Financing funds shall be used for working capital, product development and sales of the antibody markers.

All Financing Warrants (i.e. 2,600,000 warrants) and one-third of the aggregate number of Financing Shares (i.e. 433,333 common shares) shall be issued to and held in escrow by the Escrow Agent pursuant to the provisions of this Part 4, and released to the Financiers or to Pubco, as applicable, based on the provisions hereof (the "Securities Escrow").

Within eight months from the date on which the Company moves into its research facility after the Closing (the "Deadline"), Pubco shall use reasonable efforts to raise an additional amount of $950,000, to be used for development of the Intellectual Property Assets, either through the exercise of the Financing warrants or through an additional financing (the "Additional Financing").

Notwithstanding anything to the contrary herein, the Securities Escrow shall be subject to, and the Financing Warrants shall contain, the following terms:

The Financing Shares shall be restricted as to sale under United States securities laws and rules, and shall carry a restrictive legend indicating such restrictions.

If Pubco achieves one of the Milestones (as defined below) prior to the Deadline, then the Financiers, on a pro rata basis, shall exercise warrants for at least $950,000 (i.e., at least 760,000 warrants at $1.25 per common share) within 30 days after receipt of Pubco's written notice that it achieved such a Milestone (but not earlier than 90 days after the Closing). Provided that if the share price of the common shares of Pubco, as quoted on the Market (or other exchange on which the shares are traded) on the date Pubco achieves a Milestone, is less than $1.25 per share, then the directors of Pubco may, in their sole discretion, allow the Financiers to purchase, on a pro rata basis, common shares in the capital of Pubco at the then market price, in the aggregate amount of $950,000 without penalty as provided by Section 17(c) hereof. Each of the following shall be deemed a "Milestone":

sequencing of the variable region of the novel melanoma Mab and filing a patent for that Mab;

creating novel Mabs against breast cancer which react with at least three different breast cancer specimen (tissue or sera) and do not cross react with a negative control (e.g. normal tissue or serum); or

creating novel Mabs against colorectal cancer which react with at least three different colorectal cancer specimen (tissue or sera) and do not cross react with a negative control (e.g. normal tissue or serum).

In the event that a Financier defaults on its commitment to exercise its portion of such warrants per Section 17(b) hereof, then, without limiting the remedies of Pubco for such breach, all of its Financing Warrants held in escrow per Section 15 hereof shall immediately expire, and its Financing Shares held in escrow per Section 15 hereof above shall be immediately transferred to Pubco. With respect to any Financier who exercised warrants as required hereunder, the Escrow Agent shall release to such Financier its shares then held in Escrow.

In the event that Pubco achieves a Milestone as per Section 17(b) hereof but does not raise the additional $950,000 as per Section 16 hereof, then, in addition to the provisions above, Pubco shall issue an additional 5,000,000 common shares to the Vendor and the Executive in a ratio as determined by them, for no additional consideration, or pro-rata if a lesser amount is raised.

While in escrow, the Financiers shall have voting rights for the Financing Shares in escrow, and distributions of stock of Pubco made in respect of such shares shall be distributed to the Escrow Agent to be held pursuant to the same terms and conditions the Escrow Agent held the Financiers' Financing Shares. All other distributions made in respect of such Financing Shares shall be distributed directly to the Financiers.
