3.    Manner of Payment.  All amounts due and payable under this Note shall be paid in U.S. Dollars and shall be paid to Lender by wire transfer of immediately available funds in accordance with the instructions set forth on the signature page hereto.  Lender may modify such instructions by delivering notice thereof to Borrower in accordance with Section 13.
Borrower shall be entitled to deduct and withhold from any payment, such amounts as may be required to be deducted and withheld under applicable Law, including, without limitation, any such deduction and withholding with respect to the making of such payment under the Internal Revenue Code of 1986, as amended, and all rules and regulations promulgated thereunder or any other applicable tax law or regulation.
If any payment under this Note shall become due and payable on a Saturday, Sunday, or a bank or legal holiday, then such payment shall be made on the next succeeding Business Day, without additional interest, premium or penalty.
4.    Redemption.  Borrower may redeem all or any part of the then issued and OPKO Notes (the “Redemption Right”).  Borrower may exercise the Redemption Right by delivering notice to all Holders of Borrower’s exercise of the Redemption Right (the “Redemption Notice”), which Redemption Notice shall contain the following:  (i) the date on which Borrower will redeem the OPKO Notes, which shall be a date no fewer than 30 days, and no more than 60 days, immediately following the date of the Redemption Notice (the “Redemption Date”); (ii) the aggregate principal amount of OPKO Notes to be redeemed; (iii) the Redemption Price, including a reasonably detailed calculation thereof; and (iv) instructions for a Holder to deliver such Holder’s OPKO Notes to Borrower and receive in exchange therefor the Redemption Price for each $1,000 principal amount of such Holder’s OPKO Notes so delivered.  At any time prior to 5:00 p.m. New York time on the date immediately preceding the Redemption Date, a Holder may elect to convert such Holder’s Notes in accordance with Section 5(b).  Any Redemption Notices shall be applied ratably to the Holders of all OPKO Notes issued based on each Holder’s then-current OPKO Note holdings, provided that any voluntary conversions by a Holder subsequent to the date of the Redemption Notice and prior to the Redemption Date shall be applied against such Holder’s pro rata allocation, thereby decreasing the aggregate amount redeemed hereunder if less than all of the OPKO Notes are redeemed.
5.    Note Conversion; Redemption.
(a)    Conversion.  Subject to the terms and provisions hereof, this Note shall convert into shares of Borrower’s common stock, par value $0.01 (“Common Stock”), as set forth in this Section ‎5.
(b)    Optional Conversion.  At any time prior to the Maturity Date, Lender may deliver to Borrower written notice of Lender’s election to convert all or any portion of the principal amount of this Note, together with accrued but unpaid interest thereon, into shares of Common Stock (a “Conversion Notice”), in which case such aggregate principal amount of this Note, together with such accrued and unpaid interest thereon, indicated in the Conversion Notice (the “Conversion Amount”) shall convert into a number of shares of Common Stock equal to the Conversion Amount, divided by the Conversion Price then in effect.
(c)    Method of Conversion.  Conversion of this Note pursuant to Section ‎5 shall take place at any time during the usual business hours of Borrower at its principal office or at such other time 


-2-
MIA 186341270v6





and place as Borrower and Lender may agree, by the surrender for cancellation of this Note and, if so required, by a written instrument or instruments of transfer in form reasonably satisfactory to Borrower duly executed by Lender.  Borrower shall pay any applicable transfer tax.  This Note shall be deemed to have been converted as of the close of business on the Conversion Date, and Lender shall be treated for all purposes as the holder of record of such number of Common Stock, as provided in this Section ‎5, on Borrower’s books and records as of the close of business on the Conversion Date.
(d)    Share Issuance.  Borrower shall issue and deliver, on or prior to the fifth (5th) Business Day after the Conversion Date, to Lender or to the nominee of Lender, at the address of Lender on the books of Borrower or as otherwise directed by Lender in writing, a certificate evidencing the Common Stock to which Lender shall be entitled, and Borrower shall register such Common Stock in its share registry.
(e)    Reserved Common Stock.  Borrower shall at all times keep authorized and approved under its Amended and Restated Certificate of Incorporation, as may be amended from time to time, solely for the purpose of effecting the conversion of this Note and the other OPKO Notes, such number of shares of Common Stock issuable upon the conversion of this Note and the other OPKO Notes in accordance with their terms, and shall take all such action as may be required from time to time in order that it may validly and legally issue the Common Stock upon such conversion.  
(f)    Adjustment to Conversion Price.  
(i)    Adjustment for Share Splits and Combinations.  If Borrower shall at any time or from time to time after the date hereof effect a subdivision of the outstanding shares of Common Stock, then the Conversion Price in effect immediately before such subdivision shall be multiplied by a fraction (i) the numerator of which is the total number of shares of Common Stock issued and outstanding immediately prior to the time of such subdivision, and (ii) the denominator of which is the total number of shares of Common Stock issued and outstanding immediately following such subdivision.  Conversely, if Borrower shall at any time or from time to time after the date hereof combine the outstanding shares of Common Stock into a smaller number of shares, then the Conversion Price in effect immediately before the combination shall be multiplied by a fraction (i) the numerator of which is the total number of shares of Common Stock issued and outstanding immediately prior to the time of such combination, and (ii) the denominator of which is the total number of shares of Common Stock issued and outstanding immediately following such combination.  Any adjustment pursuant to this Section 5(f)(i) shall become effective at the close of business on the date the subdivision or combination becomes effective.
(ii)    Adjustment for Dividends and Distributions.  If Borrower at any time or from time to time after the date hereof makes, or fixes a record date for the determination of holders of Common Stock entitled to receive, a dividend or other distribution payable in Common Stock, then, in each such event, the Conversion Price that is then in effect shall be decreased as of the time of such issuance or, in the event such record date is fixed, as of the close of business on such record date, by multiplying the Conversion Price then in effect by a fraction (i) the numerator of which is the total number of shares of Common Stock issued and outstanding immediately prior to the time of such issuance or the close of business on such record date, and (ii) the denominator of which is the total number of shares Common Stock issued and outstanding immediately prior to the time of such issuance or the close of business on such record date 


-3-
MIA 186341270v6





plus the number of shares of Common Stock issued or issuable in payment of such dividend or distribution; provided, however, that if such record date is fixed and such dividend is not fully paid or if such distribution is not fully made on the date fixed therefor, then the Conversion Price shall be recomputed accordingly as of the close of business on such record date, and thereafter the Conversion Price shall be adjusted pursuant to this Section 5(f)(ii) to reflect the actual payment of such dividend or distribution.
(iii)    Adjustment for Reclassification, Exchange and Substitution.  If at any time or from time to time after the date hereof the Common Stock issuable upon the conversion of this Note is changed into the same or a different number of shares of any class or classes of shares, whether by recapitalization, reclassification or otherwise (other than an acquisition or asset transfer or a subdivision or combination of shares or share dividend or a reorganization, merger, consolidation or sale of assets provided for elsewhere in this Section 5(f)), then in any such event Lender, upon conversion of this Note in circumstances in which Common Stock would otherwise be issuable, shall instead be entitled to receive upon such conversion, the kind and amount of shares and other securities and property receivable upon such recapitalization, reclassification or other change by holders of the number of shares of Common Stock into which this Note would have been converted (assuming the conversion thereof) immediately prior to such recapitalization, reclassification or change, all subject to further adjustment as provided herein or with respect to such other securities or property by the terms thereof.
(iv)    Reorganizations, Mergers, Consolidations or Sales of Assets.  If any Organic Change shall be effected in such a way that holders of Common Stock shall be entitled to receive (either directly or upon subsequent liquidation) shares, securities or assets in respect of or in exchange for their shares of Common Stock, then lawful and adequate provisions shall be made whereby Lender shall thereupon have the right to receive, upon the basis and upon the terms and conditions specified herein and in lieu of Common Stock immediately theretofore receivable upon the conversion of this Note, such shares, securities or assets as may be issued or payable in respect of or in exchange for the number of outstanding shares of Common Stock that would have been immediately theretofore receivable upon conversion of this Note had such Organic Change not taken place, and in the case of any reorganization or reclassification appropriate provisions shall be made with respect to the rights and interests of Lender whereby the provisions hereof (including, without limitation, provisions for adjustments to the Conversion Price) shall thereafter be applicable, as nearly as may be, in relation to any shares, securities or assets thereafter deliverable upon the exercise of such conversion rights.
(v)    Certificate of Adjustment.  In each case of an adjustment or readjustment of the Conversion Price pursuant to Section 5(f), Borrower, at its expense, shall compute such adjustment or readjustment in accordance with the provisions hereof and prepare a certificate showing such adjustment or readjustment, and shall mail such certificate, by first class mail, postage prepaid, to Lender at in accordance with Section ‎13.  The certificate shall set forth such adjustment or readjustment, showing in reasonable detail the facts upon which such adjustment or readjustment is based.
(g)    Fractional Shares; Aggregation.  No fractional shares of Common Stock shall be issued upon conversion of this Note.  If conversion of this Note would result in the issuance of any fractional 


-4-

shares of Common Stock, then Borrower shall, in lieu of issuing any fractional share, round up to the nearest whole share.
6.    Representations and Warranties.  Borrower represents and warrants to Lender, on the date hereof, that:

(c)    This Note constitutes the legal, valid and binding obligations of Borrower, enforceable against Borrower in accordance with its terms, except as the enforcement hereof may be limited by bankruptcy, insolvency, or other Laws affecting the enforcement of creditors’ rights generally and subject to the applicability of general principles of equity; and
(d)    Except for such filings or other actions that have been made or taken on or prior to the date hereof, no consent, approval or authorization of, or registration, declaration or filing with, any Governmental Authority or other Person is required as a condition to or in connection with the due and valid execution, delivery and performance by Borrower of this Note.
7.    Affirmative Covenants.  So long as this Note remains outstanding, Borrower shall:
(a)    comply in all material respects with applicable Laws, such compliance to include, without limitation, paying before the same become delinquent all taxes, assessments and governmental charges imposed upon it or upon its property, except for good faith contests for which adequate reserves are maintained or any noncompliance which would not reasonably be expected to have a material adverse effect on Borrower;
