3. LOAN PROVISIONS.

3.1 Security Interest.

(a) Grant of Security Interest. As security for the prompt and complete payment in full of the Loans, the Company hereby grants to BSC a first priority security interest in all properties, assets and rights of the Company, wherever located, whether now owned or hereafter acquired or arising, and all proceeds and products thereof (all of the same being hereinafter called the “Collateral”), including without limitation: all personal and fixture property of every kind and nature, including, without limitation, all goods (including inventory, equipment and any accessions thereto), intellectual property (including all patents, patent applications, trade secrets, trademarks, copyrights and all other intellectual property), instruments (including promissory notes), documents, accounts, chattel paper (whether tangible or electronic), deposit accounts, letter-of-credit rights (whether or not the letter of credit is evidenced by a writing), commercial tort claims, securities and all other investment property, supporting obligations, any other contract rights or rights to the payment of money, insurance claims and proceeds, and all general intangibles (including all payment intangibles and goodwill of any kind or nature). The Company represents, warrants and agrees that, except for the security interest granted hereunder, the Company owns, and will continue to own, the Collateral free and clear of all Liens, and will not, while any Loan remains outstanding, create any Lien of any kind whatsoever on the Collateral. The Company agrees that it will assist BSC, at BSC’s request, in making such filings or taking such other actions (including, without limitation, the execution of such documents) as may be necessary or advisable for BSC to perfect its security interest hereunder (including, without limitation, executing such UCC financing statements as BSC requests and executing the Patent Security Agreement). If the Company shall be in default of the terms of the Notes, BSC shall have the rights and remedies of a secured party under the Uniform Commercial Code and any other applicable laws now or hereafter existing, all such rights and remedies being cumulative, not exclusive, and enforceable alternatively, successively or concurrently, at such time or times as BSC deems expedient.

(b) Third Party Consents. If and to the extent the Company is required to obtain a consent from one or more third parties in connection with the grant by the Company to BSC of the security interest in the Company’s contract rights, as provided in Section 3.1(a), the Company will use commercially reasonable efforts to obtain such consent(s) within one hundred eighty (180) days following the Initial Closing Date. BSC acknowledges and agrees that the Company shall not be required to obtain any such third party consents prior to the Initial Loan Closing Date or any additional Loan Closing Date. The foregoing provisions of this Section 3.1(b) shall not limit any of the other obligations of the Company or the grant by the Company of a security interest in any other assets of the Company other than contract rights.

3.2 Interest. Interest on each Loan shall accrue at the rate of ten percent (10%) per annum, compounded annually.

3.3 Repayment of Loans.

(a) Repayment. Each of the Loans shall be repayable in the manner specified in the Note for such Loan.

(b) Mandatory Prepayment. In addition, the Company shall be required to prepay the Loans as provided in this Section 3.3(b). Upon the consummation of any Qualified Financing from any Strategic Competitor, 100% of the cash proceeds from such Qualified Financing shall be applied by the Company to prepay the outstanding principal of the Loans and accrued interest thereon. Upon the consummation of any Qualified Financing from any investor other than a Strategic Competitor, 25% of the cash proceeds from such Qualified Financing shall be applied by the Company to prepay the outstanding principal of the Loans and accrued interest thereon.

3.4 Conversion. Each Note shall be convertible into shares of the Company’s capital stock in accordance with the following provisions:

(a) Optional Conversion. At the sole option of BSC, the Notes (including the entire principal amount of each of the Notes and all accrued interest then outstanding) may be converted immediately upon BSC’s delivery to the Company of written notice of its election to cause such conversion into that number of Conversion Shares as shall be equal to the Conversion Amount, calculated as of the date of receipt by the Company of such notice.

(b) Upon a Qualified Initial Public Offering or Sale of the Company. At the sole option of BSC, the Notes (including the entire principal amount of each of the Notes and all accrued interest then outstanding) may be converted, immediately prior to, and contingent upon, the consummation of a Qualified Initial Public Offering or a Sale of the Company into that number of Conversion Shares as shall be equal to the Conversion Amount. The Company shall give BSC written notice at least fifteen (15) business days prior to the consummation of a Qualified Initial Public Offering or a Sale of the Company, which notice shall describe in reasonable details the material terms of such transaction. From and after the delivery of such notice until consummation of such transaction, BSC shall be entitled to receive such other information relating to the Company and such transaction as BSC may reasonably request, and the Company agrees to provide such information to BSC promptly on request. BSC’s election to convert the Notes shall be effected by providing written notice thereof to the Company at least five (5) business days prior to the consummation of the Qualified Initial Public Offering or Sale of the Company (as the case may be).

(c) No Conversion Following a Qualified Initial Public Offering. If BSC has not elected to convert the Notes into Conversion Shares upon the consummation of a Qualified Initial Public Offering, then, notwithstanding any provision herein to the contrary, following the consummation of such Qualified Initial Public Offering, BSC shall no longer have the right to convert the Notes into Conversion Shares.

(d) Manner of Conversion. BSC shall be deemed to be the holder of the Conversion Shares in connection with a conversion pursuant to this Section 3.4 as of the date of conversion. At that time, BSC shall cease to have any rights pursuant to the Notes with respect to the principal amount and accrued interest being converted, but shall have all of the rights granted to it as a holder of the Conversion Shares into which the Notes convert. To receive a certificate representing the Conversion Shares into which the Notes convert, BSC shall surrender the Notes, or a customary affidavit of loss reasonably acceptable to the Company, to the Company (provided, that BSC shall not be required to post any bond in connection with any such affidavit of loss). As soon as practicable after the surrender of the Notes, the Company shall issue and deliver to BSC a certificate for the number of whole shares issuable upon conversion. Upon conversion of the entire principal amount and accrued but unpaid interest on the Notes into Conversion Shares as provided herein, (i) the provisions of the Notes relating to the obligations of the Company to pay principal and interest to BSC, set forth therein, shall be null and void and no payment of principal and interest shall be owed or paid by the Company to the BSC, and (ii) the security interest granted to BSC shall terminate.

(e) Covenant of the Company to Reserve Shares. At all times while there are amounts outstanding under any of the Notes, the Company covenants and agrees that it shall reserve, out of its authorized and unissued share capital, an adequate number of Conversion Shares (and any shares of any other class of share capital of the Company into which such Conversion Shares are convertible) such that, upon occurrence of a Qualified Initial Public Offering or Sale of the Company, a sufficient number of Conversion Shares may be immediately issued upon conversion pursuant to this Section 3.4.

3.5 No Obligation to Request Loan. The Company is under no obligation to request any Loan, and may elect to request any Loan, or not, in its sole discretion.

In particular, BSC is aware that the Notes and the Conversion Shares may not be sold pursuant to Rule 144 promulgated under the Securities Act unless all of the conditions of Rule 144 are met.

BSC understands that the Notes and Conversion Shares will contain appropriate state and federal legends.

the Company or any of its subsidiaries that, with other such outstanding final judgments against the Company or any of its subsidiaries that are undischarged, unsatisfied, unvacated, unbonded or unstayed, exceeds in the aggregate $500,000 in excess of insurance coverage, or (j) this Note shall be cancelled, terminated, revoked or rescinded, or any action at law, suit or in equity or other legal proceeding to cancel, revoke or rescind this Note shall be commenced by or on behalf of the Company or any of its subsidiaries party thereto or any of their respective shareholders, or any court or any other governmental or regulatory authority or agency of competent jurisdiction shall make a determination that, or issue a judgment, order, decree or ruling to the effect that, this Note is illegal, invalid or unenforceable in accordance with the terms thereof.
