1.2(b)2. Event of Reversion - In the event Investor fails to fund any Successive Closing pursuant to Schedule “A-2” (each failure to fund, an “Event of Reversion”), then any IP Interest previously acquired by the Investor shall as of that date be irrevocably and unconditionally relinquished and automatically forfeited by the Investor and shall automatically revert back to the Company as of the date of the Unfunded Closing. Investor, however, shall still have the obligation to fund any and all Successive Closing(s) and shall have the right to acquire any IP Interest associated with any such Successive Closing(s), only. Notwithstanding any failure to fund by the Investor, Investor shall still be entitled to receive payments of Principal and Interest pursuant to Sections 2 and 2.a of the Note, for all funds received by the Company regardless of when the funding occurs. By participating in this Agreement, each Investor hereby acknowledges and agrees that there shall be no excuse of performance of Investor’s obligation to fund any and all Successive Closings, time being of the essence. Investor further acknowledges and agrees that the Company will not send any notices to perform under this Agreement, it being specifically understood and agreed that it is the Investor’s responsibility to perform and fund all Successive Closings agreed to in this Agreement without any further notice from the Company.

1.2(b)3. Event of Termination – In the event the Qualcomm litigation is fully and finally resolved or settled, or in the event of a final judgment in the Qualcomm litigation, or in the event of dismissal of the Qualcomm litigation for any reason, no Investor under the Option A-2 Investment Schedule shall have any further right to loan any further funds to the company pursuant to any future Note or Successive Closing. For the avoidance of doubt, if the Qualcomm litigation were to be settled or otherwise finally disposed of in November 2010, Investor would no longer have the right to invest in a Third Note or a Fourth Note or any other Successive Closing.

Initials: ______

1.2(b)4. Right to Terminate - In the event the Company has failed to obtain new lead trial counsel acceptable to the Company’s Board of Directors in connection with the Company’s representation in the Qualcomm litigation on or before the Second Closing (as defined herein), then the Option A-2 Investors shall have the right to terminate the Second, Third or Fourth Closings by providing 30 days written notice to the Company, without forfeiture of any IP Interest previously acquired by the Investor during a previous Closing held under this Agreement.

1.3 Sale and Issuance of Notes at Second, Third and Fourth Closings. Subject to this Section 1.3, after the Initial Closing, the Company shall deliver additional IP Interest to the Initial Investors who have elected to fund the Promissory Note pursuant to the Option A-2 Investment Schedule: (i) in the amount of funds stated in the Promissory Note, at a second closing which shall take place at the Closing Location, on or before Noon Central Time, on August 23, 2010, but in no event sooner than five (5) business days prior to said date (which time and place is designated as the “Second Closing”); (ii) in the amount of funds stated in the Promissory Note, at a third closing which shall take place at the Closing Location, on or before Noon Central Time, on February 23, 2011, but in no event sooner than five (5) business days prior to said date (which time and place is designated as the “Third Closing,”); and (iii) in the amount of funds stated in the Promissory Note, at a fourth closing which shall take place at the Closing Location, on or before Noon Central Time, on August 23, 2011, but in no event sooner than five (5) business days prior to said date (which time and place is designated as the “Fourth Closing” and collectively referred to herein along with the Initial, Second and Third Closings as the “Closings,” or, as applicable, each individually as the “Second Closing”, the “Third Closing”, or the “Fourth Closing”). In the event Investor fails to make a purchase on or before any “Second Closing” date, “Third Closing” date, or “Fourth Closing” date (“Unfunded Closing”), then the provisions of sub-paragraph 1.2(b)2 shall apply. The Second, Third and Fourth Closings are sometimes herein referred to each individually as a “Successive Closing” and collectively as “Successive Closings.”

1.4 Investor Covenants. The representations and warranties of the Company set forth in Section 2 hereof shall be reaffirmed and in full force and effect as of the date of each Closing, and the representations and warranties of each applicable Investor in Section 3 hereof shall be reaffirmed and in full force and effect as of the date of the Closing. At the Closing, the Company shall deliver to each Investor the original Note that such Investor purchases at the Closing upon confirmation of receipt of payment of the Purchase Price therefore, which Purchase Price shall equal the principal amount of the Note purchased, and shall be paid in cash by wire transfer to the Company, pursuant to the instructions attached hereto as Exhibit “B”.

Promissory Note Purchase Agreement

$____________

March____, 2010

FOR VALUE RECEIVED, the undersigned, Gabriel Technologies Corporation, a Delaware corporation (“Company”), promises to pay to the order of ______________________ (“Lender”) the principal sum of _________________________ Dollars ($____________) (the “Principal”), pursuant to the Promissory Note Purchase Agreement executed by Lender contemporaneously herewith, at the Interest Rate hereinafter defined, which amount shall be due and payable in lawful money of the United States of America at such place as Lender may from time to time designate, at the time and in accordance with the terms and conditions provided in Sections 2 below.

1. Interest Rate and Maturity Date. Interest shall accrue on the Principal at six percent (6.00%) per annum (the “Interest Rate”) commencing on the date of this Note. Interest shall be computed on the actual number of days elapsed based on a 365-day year. The balance of the Principal sum and all Interest thereon shall be due and payable on the funding of the IP Event (as defined below) (the “Maturity Date”). For the purposes of this Note, “IP Event” is defined as the recovery and/or receipt by the Company or any of its subsidiaries of any amount paid or to be paid by or on behalf of any person, entity, defendant or third party, or the amount of other value received, including the present fair market value of any business/non-monetary consideration, which amounts relate directly or indirectly to the Qualcomm Dispute, as defined below, regardless of whether such payments are made in cash, stock, by payment or assumption of Company liabilities, or otherwise, and regardless of whether such payment is styled as an amount paid in settlement, a royalty, a licensing fee, a purchase price for the sale or transfer of stock or assets of the Company or any of its subsidiaries, merger consideration or otherwise. The “Qualcomm Dispute” is defined as, without limitation, all claims asserted by the Company in Civil Action No. 3:08-CV-1992 pending in the United States District Court for the Southern District of California, San Diego Division.

A-1

2. Payments of Principal and Interest. To the extent funds are available from the Net Proceeds (as hereinafter defined) of an IP Event, and to the extent Lender is not in Breach of the Note Purchase Agreement, or to the extent this Agreement is not Terminated [ie: Event of Termination, as defined in the Note Purchase Agreement, para. 1.2(b)3] or to the extent an Investor has not exercised his Right to Terminate [ie: Right of Termination, as defined in the Note Purchase Agreement, para. 1.2(b)4], the Company shall pay to each Lender (on a pro-rata basis) in this round of financing, payments of Principal and Interest, with all payment amounts being applied first to accrued Interest and then to Principal, from the “Net Proceeds” of the IP Event which for purposes of this Note shall mean IP Event proceeds after deduction of all company expenses and obligations required to be paid by the company (“Expenses”), which include but are not limited to: IP Event expenses, fees, court costs, any and all financing expenses , litigation costs, all attorneys fees (but not including any Qualcomm Dispute IP Event percentage/contingent attorneys fees), obligations to the IRS and other Federal, State and local tax authorities, employee wages, secured loans, judgments and all company debts. If full repayment of Interest and Principal is not made after the payment to Lender from the first IP Event, then Lender shall be paid from each successive IP Event in proportion to the amount of the funding received by the Company (i.e. if the Company receives the IP Event funding in five (5) separate fundings, then the Investor(s) shall receive the total amounts due to them in five (5) separate fundings with each payment to the Investor(s) in equal proportion to the amount received by the Company), until Lender is paid all Interest and Principal due and owing.

2.a. Modification of Definition of “Expenses” and “Net Proceeds”. In the event of an IP Event recognizing an amount less than $150,000,000.00 in proceeds (“Minimum IP Threshold”), the definition of “Expenses” in Section 2 above shall include Qualcomm Dispute IP Event percentage/contingent attorneys fees, and the resulting “Modified Net Proceeds” shall be adjusted accordingly.

2.1 Lien. To the extent Lender is not in Breach of the Note Purchase Agreement (ie: Event of Reversion as defined in the Note Purchase Agreement), Lender shall have a lien, for all unpaid sums due under this Note, on all claims or causes of action that are the subject of any event set forth above in this Section 2. This lien shall attach to any recovery, whether by settlement, award, verdict, judgment, or other order.

2.2 Additional Benefits. In addition to the Principal amount and Interest on this Note, in return for every $100,000.00 loaned by a Lender to the Company, to the extent funds are available following the deduction of all Expenses (i.e., from Net Proceeds or Modified Net Proceeds as the case may be), and the repayment of all Principal and accrued Interest (“Net Profit” defined as Net Proceeds or Modified Net Proceeds minus all Principal and accrued Interest), Lender shall have the right to receive eight tenths of one percent (0.80%) of the Net Profit (the “Additional Benefit”) [“Additional Benefit” is also referred to as “IP Interest” in the Promissory Note Purchase Agreement]. In the event a Lender loans the Company an amount less than $100,000.00 pursuant to this Note, said Lender shall receive a pro-rata portion of the aforementioned Additional Benefit. Payment of the Additional Benefits described in this Section 2.2 shall be made no later than ten (10) business days after the final and complete funding by the funding party of the IP Event.

A-2

3. Attorney’s Fees. If the indebtedness represented by this Note or any part thereof is collected in bankruptcy, receivership or other judicial proceedings or if this Note is placed in the hands of attorneys for collection after default, the Company agrees to pay, in addition to the Principal and Interest payable hereunder, reasonable attorney’s fees and costs incurred by Lender.

4. Pari Passu; Notes, Subordination. The Lender acknowledges and agrees that the payment of all or any portion of the outstanding Principal amount of this Note and all Interest hereon shall be pari passu in right of payment and in all other respects to the other Notes. In the event the Lender receives payments in excess of the Lender’s pro rata share of the Company’s payments to the holders of all of the Notes outstanding, then the Lender shall hold in trust all such excess payments for the benefit of the holders of the other Notes and shall pay such amounts held in trust to such other holders upon demand by such holders. The Lender acknowledges and agrees that this Note will be subordinate in priority and right of payment to all current and future indebtedness of the Company to banks and other financial institutions which may be required for secured financing in the future, and that no other writing shall be required to affect same.

5. Surrender of Note. The Lender shall surrender this Note pursuant to the foregoing provisions.

EXHIBIT “C”

GABRIEL TECHNOLOGIES CORPORATION CORPORATE DISCLOSURE DOCUMENT

1.	Withdrawal of Former Attorneys

Gabriel came to the end of its relationship with its former attorneys in the Qualcomm case and in other Gabriel corporate, patent, etc. matters at the end of 2009. Gabriel is now in arbitration with its former attorneys on the matter of attorneys' fees and potentially other matters. Gabriel's directors believe that the termination of this relationship was/is in the best interests of Gabriel in general, and particularly in its efforts against Qualcomm. We expect Gabriel's California counsel to remain involved in the Qualcomm case for the foreseeable future.

2.	New Gabriel Attorneys For Qualcomm Case

After a diligent search, Gabriel is working to engage one of several well-qualified law firms to succeed our former attorneys in the Qualcomm case. We hope to make an announcement in the next month or so that a new law firm is representing Gabriel as lead trial counsel against Qualcomm.

3.	Next Stages of Qualcomm Lawsuit

Gabriel's Fourth Amended Complaint in the Qualcomm lawsuit was med January 11, 2010. Qualcomm's Answer to Gabriel's Fourth Amended Complaint was filed on or about January 21. We expect discovery to begin as soon as parties meet and confer to establish a discovery plan - likely within the next 30 to 60 days.

4.	Gabriel Historical Financial Statements

Under the management of its former officer and directors, Gabriel did not file reports with the SEC, including historical financial statements, since 2006. The current management has prepared Gabriel's 2007 annual financial statements, and is working with the Gabriel auditors to formalize them. We intend to file Gabriel's historical annual financial statements with the SEC and make them public when this work is completed. As part of the audit process, Gabriel's auditors will be examining financial statements filed by Gabriel in 2006 and before - to assure the accuracy of those previously filed financial statements. The current Gabriel management and directors cannot verify as accurate the previously filed financial statements of Gabriel, until this audit process is complete.

C-1

5.	Action Against Select Former Gabriel Officers, Directors and Third Parties

An action against select former Gabriel officers and directors, and certain third parties, was filed in 2008 at the direction of the former directors of Gabriel. The current Gabriel directors have been assessing this lawsuit, and believe that it may be insufficient in its naming of alleged defendants and in the causes of action alleged. Gabriel's primary goal in this lawsuit is to possibly recapture for Gabriel monies, securities, and/or interests in the Qualcomm case from persons/entities who may have received them improperly. New counsel has been retained to reassess this lawsuit and to make recommendations to the directors as to the possible filing of an amended complaint.

6.	Gabriel Operations Financing Transaction

Although approximately $5.7 million was invested in Gabriel in late 2007 and early 2008, when the new Gabriel directors were appointed in June of 2009 Gabriel had little or no cash on hand, and was more than $800,000 past due in its payments to its attorneys, its landlord, its insurers, and other creditors. An investment group, including several of Gabriel's current directors, furnished Gabriel approximately $1 million of financing in 2009; however, this financing is insufficient to pay for future operations of Gabriel. Therefore, Gabriel recently completed a $500,000 short-term debt transaction to provided needed funds to pay continuing operations of the Company, and Gabriel is now working with its investment bankers on a possible means of securing long-term financing of Gabriel's operations. Any and all long-term operations financing transactions entered into by Gabriel will be completed only as necessary, only on the most favorable terms available to Gabriel, and only upon advice and approval of Gabriel's investment bankers and other advisors that such transactions are fair to the shareholders of Gabriel. There can be no assurance, however, whether or on what terms, Gabriel will be able to complete a long-term financing.

7.	Assignment of Interests in Possible Proceeds of Qualcomm Lawsuit

In connection with certain financing transactions by Gabriel, and to pay Gabriel's creditors, Gabriel's former directors began the practice, several years ago, of assigning percentage interests in a settlement amount or favorable judgment, if any, that may be obtained by Gabriel in its action against Qualcomm. We are currently reevaluating this practice. In the meantime, you should be aware that we estimate that the total percentage interests in the possible proceeds from the Qualcomm lawsuit that previously have been committed by Gabriel, and that might be committed by Gabriel to third parties, etc. in the foreseeable future, will be not less than seventy-five percent (75%) and may be as much as ninety-five percent (95%). This estimate includes the possible percentage interests that we may assign in connection with the engagement of new lead trial counsel, to obtain litigation financing, and to procure long-term financing for Gabriel. These interests of third parties in any proceeds from the Qualcomm lawsuit effectively reduce the amount of such proceeds, if any, that will be available to Gabriel and its shareholders. Of course, there can be no assurance that Gabriel will be able financially to continue to prosecute the Qualcomm lawsuit or, if so, that it will achieve a favorable outcome or receive any significant proceeds from that lawsuit.

8. Actions Taken Prior To Appointment of New Gabriel Directors

Prior to the current Gabriel directors appointment earlier this year, actions taken at Gabriel over the past several years include, but were not limited to:

A. Issuance of all sixty million authorized shares of Gabriel’s stock (and possibly more than sixty million authorized shares of Gabriel’s stock), in the form of stock, and/or stock warrants, and/or Stock Equivalent Units, and or otherwise;

B. Subsequent to the issuance of all authorized stock/warrants, the issuance of stock equivalency units, or SEUs, which are the equivalent of common stock. The total amount of SEUs issued is being ascertained, as there is no transfer agent for such securities as SEUs to track their issuance;

C. Investment in Gabriel of $5.7 million in short-term notes, some of which are redeemable by the note holders for double their face value beginning in January 2011;

D. Expenditures by Gabriel on corporate matters alone (i.e. not including attorneys fees to prosecute the Company’s legal action with Qualcomm) with Gabriel’s former attorneys - in excess of $1 million;

E. The former directors’ issuance to themselves of percentage interests in the result of Gabriel’s action against Qualcomm;

F. The failure to hold an annual shareholders meeting within the past three years. A Company annual shareholders meeting still cannot be held due to the failure to have current financials filed with the SEC. This fact continues to hamper Gabriel’s efforts to raise financing for the Company, since additional Gabriel stock cannot be authorized by Delaware State authorities without such a shareholders meeting approving such additional stock authorization. This requires the Gabriel directors to continue to rely on the possible proceeds, if any, of Gabriel’s action against Qualcomm to obtain needed financing for the Company.

9. No Lead Trial Counsel and No Litigation Funding for Action vs Qualcomm – The Company is currently searching for both lead trial counsel and funding to prosecute its action vs Qualcomm. The Company cannot represent nor guarantee that the Company will obtain either lead trial counsel or funding to prosecute its action vs Qualcomm.

C-3

10. Arbitration Action By Former Company President and COO – The Company was recently served (on or about 2/3/10) with a Demand For Arbitration by Ron Gillum (the “Demand”), the Company’s former President and CEO. The Company believes it has sufficient defenses to the Demand to overcome its claims, but there is no guarantee of a successful outcome of the Demand in favor of the Company. The primary claims of the Demand are severance pay, repayment of loans made by Mr. Gillum, and other claims. The total monetary amount of the Demand is approximately two hundred and fifty thousand dollars ($250,000).
