THE SECURITIES REPRESENTED HEREBY MAY NOT BE OFFERED, SOLD OR TRANSFERRED IN THE ABSENCE OF AN EFFECTIVE REGISTRATION STATEMENT FOR THE SECURITIES UNDER APPLICABLE SECURITIES LAWS UNLESS OFFERED, SOLD OR TRANSFERRED PURSUANT TO AN AVAILABLE EXEMPTION FROM THE REGISTRATION REQUIREMENTS OF THOSE LAWS. Right to Purchase __________ Shares of Common Stock, par value $.001 per share Date: June 29, 2001 FORM OF VIROLOGIC, INC. STOCK PURCHASE WARRANT [The Schedule of Warrantholders is attached hereto as Addendum A.] THIS CERTIFIES THAT, for value received, ______________________________, or its registered assigns, is entitled to purchase from ViroLogic, Inc., a corporation organized under the laws of the State of Delaware (the "COMPANY"), at any time or from time to time during the period specified in Section 2 hereof, ______________________________________________________ (________) fully paid and nonassessable shares of the Company's common stock, par value $.001 per share (the "COMMON STOCK"), at an exercise price per share (the "EXERCISE PRICE") equal to $2.805. The number of shares of Common Stock purchasable hereunder (the "WARRANT SHARES") and the Exercise Price are subject to adjustment as provided in Section 4 hereof. The term "WARRANTS" means this Warrant and the other warrants of the Company issued pursuant to that certain Securities Purchase Agreement, dated as of June 29, 2001, by and among the Company and the other signatories thereto (the "SECURITIES PURCHASE AGREEMENT"). 1 2 This Warrant is subject to the following terms, provisions and conditions: 1. Manner of Exercise; Issuance of Certificates; Payment for Shares. Subject to the provisions hereof, including, without limitation, the limitations contained in Section 7 hereof, this Warrant may be exercised by the holder hereof, in whole or in part, by the surrender of this Warrant, together with a completed exercise agreement in the form attached hereto (the "EXERCISE AGREEMENT"), to the Company during normal business hours on any business day at the Company's principal executive offices (or such other office or agency of the Company as it may designate by notice to the holder hereof), and (i) payment to the Company in cash, by certified or official bank check or by wire transfer for the account of the Company, of the Exercise Price for the Warrant Shares specified in the Exercise Agreement or (ii) if the holder is effectuating a Cashless Exercise (as defined in Section 11(c) hereof) pursuant to Section 11(c) hereof, delivery to the Company of a written notice of an election to effect a Cashless Exercise for the Warrant Shares specified in the Exercise Agreement. The Warrant Shares so purchased shall be deemed to be issued to the holder hereof or such holder's designee, as the record owner of such shares, as of the close of business on the date on which this Warrant shall have been surrendered, the completed Exercise Agreement shall have been delivered, and payment shall have been made for such shares as set forth above or, if such date is not a business date, on the next succeeding business date. The Warrant Shares so purchased, representing the aggregate number of shares specified in the Exercise Agreement, shall (by the Company or through its transfer agent) be delivered (i.e., deposited with a nationally-recognized overnight courier service postage prepaid) to the holder hereof within a reasonable time, not exceeding two business days, after this Warrant shall have been so exercised (the "DELIVERY PERIOD"). If the Company's transfer agent is participating in the Depository Trust Company ("DTC") Fast Automated Securities Transfer program, and so long as the certificates therefor do not bear a legend (pursuant to the terms of the Securities Purchase Agreement) and the holder is not obligated to return such certificate for the placement of a legend thereon (pursuant to the terms of the Securities Purchase Agreement), the Company shall cause its transfer agent to electronically transmit the Warrant Shares so purchased to the holder by crediting the account of the holder or its nominee with DTC through its Deposit Withdrawal Agent Commission system ("DTC TRANSFER"). If the aforementioned conditions to a DTC Transfer are not satisfied, the Company shall deliver as provided herein to the holder physical certificates representing the Warrant Shares so purchased. Further, the holder may instruct the Company to deliver to the holder physical certificates representing the Warrant Shares so purchased in lieu of delivering such shares by way of DTC Transfer. Any certificates so delivered shall be in such denominations as may be reasonably requested by the holder hereof, shall be registered in the name of such holder or such other name as shall be designated by such holder and, following the date on which the Warrant Shares have been registered under the Securities Act pursuant to that certain Registration Rights Agreement, dated as of June 29, 2001, by and between the Company and the other signatories thereto (the "REGISTRATION RIGHTS AGREEMENT") or otherwise may be sold by the holder pursuant to Rule 144 promulgated under the Securities Act (or a successor rule), shall not bear any restrictive legend. If this Warrant shall have been exercised only in part, then the Company shall, at its expense, at the time of delivery of such certificates, deliver to the holder a new Warrant representing the number of shares with respect to which this Warrant shall not then have been exercised. 2 3 If, at any time, a holder of this Warrant submits this Warrant, an Exercise Agreement and payment to the Company of the Exercise Price for each of the Warrant Shares specified in the Exercise Agreement (including pursuant to a Cashless Exercise), and the Company fails for any reason to deliver, on or prior to the fourth business day following the expiration of the Delivery Period for such exercise, the number of shares of Common Stock to which the holder is entitled upon such exercise (an "EXERCISE DEFAULT"), then the Company shall pay to the holder payments ("EXERCISE DEFAULT PAYMENTS") for an Exercise Default in the amount of (a) (N/365), multiplied by (b) the amount by which the Market Price (as defined in Section 4(l) hereof) on the date the Exercise Agreement giving rise to the Exercise Default is transmitted in accordance with this Section 1 (the "EXERCISE DEFAULT DATE") exceeds the Exercise Price in respect of such Warrant Shares, multiplied by (c) the number of shares of Common Stock the Company failed to so deliver in such Exercise Default, multiplied by (d) .18, where N = the number of days from the Exercise Default Date to the date that the Company effects the full exercise of this Warrant which gave rise to the Exercise Default. The accrued Exercise Default Payment for each calendar month shall be paid in cash or shall be convertible into Common Stock, at the holder's option, as follows: (a) In the event holder elects to take such payment in cash, cash payment shall be made to holder by the fifth day of the month following the month in which it has accrued; and (b) In the event holder elects to take such payment in Common Stock, the holder may convert such payment amount into Common Stock (in accordance with the terms, conditions and limitations contained in Article IV of the Certificate of Designations, Preferences and Rights (the "CERTIFICATE OF DESIGNATION") governing the Company's Series A Convertible Preferred Stock (the "SERIES A PREFERRED STOCK")) at the lower of the Exercise Price or the Market Price (as defined in Section 4(l)) (as in effect at the time of conversion) at any time after the fifth day of the month following the month in which it has accrued. Nothing herein shall limit the holder's right to pursue actual damages for the Company's failure to maintain a sufficient number of authorized shares of Common Stock as required pursuant to the terms of Section 3(b) hereof or to otherwise issue shares of Common Stock upon exercise of this Warrant in accordance with the terms hereof, and the holder shall have the right to pursue all remedies available at law or in equity (including a decree of specific performance and/or injunctive relief). 2. Period of Exercise. This Warrant is immediately exercisable, at any time or from time to time on or after the date of initial issuance of this Warrant (the "ISSUE DATE") and before 5:00 p.m., New York City time, on the fourth anniversary of the Issue Date (the "EXERCISE PERIOD"). The Exercise Period shall automatically be extended by one (1) day for each day on which the Company does not have a number of shares of Common Stock reserved for issuance upon exercise hereof at least equal to the number of shares of Common Stock issuable upon exercise hereof. 3. Certain Agreements of the Company. The Company hereby covenants and agrees as follows: 3 4 (a) Shares to be Fully Paid. All Warrant Shares will, upon issuance in accordance with the terms of this Warrant, be validly issued, fully paid, and nonassessable and free from all taxes, liens, claims and encumbrances. (b) Reservation of Shares. During the Exercise Period, the Company shall at all times have authorized, and reserved for the purpose of issuance upon exercise of this Warrant, a sufficient number of shares of Common Stock to provide for the exercise in full of this Warrant (without giving effect to the limitations on exercise set forth in Section 7(g) hereof). (c) Listing. The Company shall promptly secure the listing of the shares of Common Stock issuable upon exercise of this Warrant upon each national securities exchange or automated quotation system, if any, upon which shares of Common Stock are then listed or become listed (subject to official notice of issuance upon exercise of this Warrant) and shall maintain, so long as any other shares of Common Stock shall be so listed, such listing of all shares of Common Stock from time to time issuable upon the exercise of this Warrant; and the Company shall so list on each national securities exchange or automated quotation system, as the case may be, and shall maintain such listing of, any other shares of capital stock of the Company issuable upon the exercise of this Warrant if and so long as any shares of the same class shall be listed on such national securities exchange or automated quotation system. (d) Certain Actions Prohibited. The Company will not, by amendment of its charter or through 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 to be observed or performed by it hereunder, but will at all times in good faith assist in the carrying out of all the provisions of this Warrant and in the taking of all such action as may reasonably be requested by the holder of this Warrant in order to protect the economic benefit inuring to the holder hereof and the exercise privilege of the holder of this Warrant against dilution or other impairment, consistent with the tenor and purpose of this Warrant. Without limiting the generality of the foregoing, the Company (i) will not increase the par value of any shares of Common Stock receivable upon the exercise of this Warrant above the Exercise Price then in effect, and (ii) will take all such actions as may be necessary or appropriate in order that the Company may validly and legally issue fully paid and nonassessable shares of Common Stock upon the exercise of this Warrant. (e) Successors and Assigns. This Warrant will be binding upon any entity succeeding to the Company by merger, consolidation, or acquisition of all or substantially all of the Company's assets. (f) Blue Sky Laws. The Company shall, on or before the date of issuance of any Warrant Shares, take such actions as the Company shall reasonably determine are necessary to qualify the Warrant Shares for, or obtain exemption for the Warrant Shares for, sale to the holder of this Warrant upon the exercise hereof under applicable securities or "blue sky" laws of the states of the United States, and shall provide evidence of any such action so taken to the holder of this Warrant prior to such date; provided, however, that the Company shall not be required in connection therewith or as a condition thereto to (a) qualify to do business in any jurisdiction where it would 4 5 not otherwise be required to qualify but for this Section 3(f), (b) subject itself to general taxation in any such jurisdiction or (c) file a general consent to service of process in any such jurisdiction. 4. Antidilution Provisions. During the Exercise Period, the Exercise Price and the number of Warrant Shares issuable hereunder shall be subject to adjustment from time to time as provided in this Section 4. In the event that any adjustment of the Exercise Price as required herein results in a fraction of a cent, such Exercise Price shall be rounded up or down to the nearest cent. (a) Adjustment of Exercise Price. Except as otherwise provided in Sections 4(c) and 4(e) hereof, if and whenever prior to the second anniversary of the Issue Date the Company issues or sells, or in accordance with Section 4(b) hereof is deemed to have issued or sold, any shares of Common Stock for no consideration or for a consideration per share less than the Exercise Price on the Measurement Date (as such terms are hereinafter defined) (a "DILUTIVE ISSUANCE"), then effective immediately upon the Dilutive Issuance, the Exercise Price will be adjusted to equal the per share amount of such shares of Common Stock issued or sold, or deemed to have been issued of sold, in such Dilutive Issuance. Notwithstanding the foregoing, no adjustment shall be made pursuant to this Section 4(a) if such adjustment would result in an increase in the Exercise Price. (b) Effect on Exercise Price of Certain Events. For purposes of determining the adjusted Exercise Price under Section 4(a) hereof, the following will be applicable: (i) Issuance of Rights or Options. If the Company in any manner issues or grants any warrants, rights or options, whether or not immediately exercisable, to subscribe for or to purchase Common Stock or other securities exercisable, convertible into or exchangeable for Common Stock ("CONVERTIBLE SECURITIES") (such warrants, rights and options to purchase Common Stock or Convertible Securities are hereinafter referred to as "OPTIONS") and the price per share for which Common Stock is issuable upon the exercise of such Options (and the price of any conversion of Convertible Securities, if applicable) is less than the Exercise Price in effect on the Measurement Date of such securities ("BELOW MARKET OPTIONS"), then the maximum total number of shares of Common Stock issuable upon the exercise of all such Below Market Options (assuming full exercise, conversion or exchange of Convertible Securities, if applicable) will, as of the date of the issuance or grant of such Below Market Options, be deemed to be outstanding and to have been issued and sold by the Company for such price per share. For purposes of the preceding sentence, the "price per share for which Common Stock is issuable upon the exercise of such Below Market Options" is determined by dividing (i) the total amount, if any, received or receivable by the Company as consideration for the issuance or granting of all such Below Market Options, plus the minimum aggregate amount of additional consideration, if any, payable to the Company upon the exercise of all such Below Market Options, plus, in the case of Convertible Securities issuable upon the exercise of such Below Market Options, the minimum aggregate amount of additional consideration payable upon the exercise, conversion or exchange thereof (determined in accordance with the calculation method set forth in (b)(ii) below) at the time such Convertible Securities first become exercisable, convertible or exchangeable, by (ii) the maximum total number of shares of 5 6 Common Stock issuable upon the exercise of all such Below Market Options (assuming full conversion of Convertible Securities, if applicable). No further adjustment to the Exercise Price will be made upon the actual issuance of such Common Stock upon the exercise of such Below Market Options or upon the exercise, conversion or exchange of Convertible Securities issuable upon exercise of such Below Market Options. If, in any case, the total number of shares of Common Stock issuable upon exercise of any Below Market Options or upon exercise, conversion or exchange of any Convertible Securities is not, in fact, issued and the rights to exercise such option or to exercise, convert or exchange such Convertible Securities shall have expired or terminated, the Exercise Price then in effect will be readjusted to the Exercise Price which would have been in effect at the time of such expiration or termination had such Below Market Options or Convertible Securities, to the extent outstanding immediately prior to such expiration or termination (other than in respect of the actual number of shares of Common Stock issued upon exercise or conversion thereof), never been issued. (ii) Issuance of Convertible Securities. (A) If the Company in any manner issues or sells any Convertible Securities, which Convertible Securities do not have a fluctuating conversion or exercise price or exchange ratio, whether or not immediately convertible (other than where the same are issuable upon the exercise of Options) and the price per share for which Common Stock is issuable upon such exercise, conversion or exchange (as determined pursuant to Section 4(b)(ii)(B) if applicable) is less than the Exercise Price in effect on the Measurement Date, then the maximum total number of shares of Common Stock issuable upon the exercise, conversion or exchange of all such Convertible Securities will, as of the date of the issuance of such Convertible Securities, be deemed to be outstanding and to have been issued and sold by the Company for such price per share. For the purposes of the preceding sentence, the "price per share for which Common Stock is issuable upon such exercise, conversion or exchange" is determined by dividing (i) the total amount, if any, received or receivable by the Company as consideration for the issuance or sale of all such Convertible Securities, plus the minimum aggregate amount of additional consideration, if any, payable to the Company upon the exercise, conversion or exchange thereof at the time such Convertible Securities first become exercisable, convertible or exchangeable, by (ii) the maximum total number of shares of Common Stock issuable upon the exercise, conversion or exchange of all such Convertible Securities. No further adjustment to the Exercise Price will be made upon the actual issuance of such Common Stock upon exercise, conversion or exchange of such Convertible Securities. (B) If the Company in any manner issues or sells any Convertible Securities with a fluctuating conversion or exercise price or exchange ratio (a "VARIABLE RATE CONVERTIBLE SECURITY"), then the "price per share for which Common Stock is issuable upon such exercise, conversion or exchange" for purposes of the calculation contemplated by Section 4(b)(ii)(A) shall be deemed to be the lowest price per share which would be applicable (assuming all holding period and other conditions to any discounts contained in such Convertible Security have been satisfied) if the Exercise Price on the Measurement Date of such Convertible Security was 75% of the Exercise Price on such date (the "ASSUMED VARIABLE EXERCISE PRICE"). Further, if the Exercise Price at any time or times thereafter is less then or equal to the Assumed Variable Exercise 6 7 Price last used for making any adjustment under this Section 4 with respect to any Variable Rate Convertible Security, the Exercise Price in effect at such time shall be readjusted to equal the Exercise Price which would have resulted if the Assumed Variable Exercise Price at the time of issuance of the Variable Rate Convertible Security had been 75% of the Exercise Price existing at the time of the adjustment required by this sentence. (iii) Change in Option Price or Conversion Rate. If there is a change at any time in (i) the amount of additional consideration payable to the Company upon the exercise of any Options; (ii) the amount of additional consideration, if any, payable to the Company upon the exercise, conversion or exchange of any Convertible Securities; or (iii) the rate at which any Convertible Securities are convertible into or exchangeable for Common Stock (in each such case, other than under or by reason of provisions designed to protect against dilution and except when an adjustment is made pursuant to (ii)(B) above), the Exercise Price in effect at the time of such change will be readjusted to the Exercise Price which would have been in effect at such time had such Options or Convertible Securities still outstanding provided for such changed additional consideration or changed conversion rate, as the case may be, at the time initially granted, issued or sold. (iv) Calculation of Consideration Received. If any Common Stock, Options or Convertible Securities are issued, granted or sold for cash, the consideration received therefor for purposes of this Warrant will be the amount received by the Company therefor, after deduction of all commissions, underwriting discounts or allowances and other expenses paid or incurred by the Company in connection with such issuance, grant or sale. In case any Common Stock, Options or Convertible Securities are issued or sold for a consideration part or all of which shall be other than cash, including in the case of a strategic or similar arrangement in which the other entity will provide services to the Company, purchase services from the Company or otherwise provide intangible consideration to the Company, the amount of the consideration other than cash received by the Company (including the net present value of the consideration expected by the Company for the provided or purchased services) will be the fair market value of such consideration, except where such consideration consists of securities, in which case the amount of consideration received by the Company will be the Market Price thereof as of the date of receipt. In case any Common Stock, Options or Convertible Securities are issued in connection with any merger or consolidation in which the Company is the surviving corporation, the amount of consideration therefor will be deemed to be the fair market value of such portion of the net assets and business of the non-surviving corporation as is attributable to such Common Stock, Options or Convertible Securities, as the case may be. Notwithstanding anything else herein to the contrary, if Common Stock, Options or Convertible Securities are issued, granted or sold in conjunction with each other as part of a single transaction or in a series of related transactions, the holder of this Warrant may elect to determine the amount of consideration deemed to be received by the Company therefore by deducting the fair value of any type of securities (the "DISREGARDED SECURITIES") issued, granted or sold in such transaction or series of transactions. If the holder makes an election pursuant to the immediately preceding sentence, no adjustment to the Exercise Price shall be made pursuant to this Section 4 for the issuance of the Disregarded Securities or upon any conversion or exercise thereof. For example, if the Company were to issue convertible notes having a face value of $1,000,000 and warrants to purchase shares of Common Stock at an exercise price equal to the market price of the 7 8 Common Stock on the date of issuance of such warrants in exchange for $1,000,000 of consideration, the fair value of the warrants would be subtracted from the $1,000,000 of consideration received by the Company for the purposes of determining whether the shares of Common Stock issuable upon conversion of the convertible notes shall be deemed to be issued at a price per share below market price and, if so, for purposes of determining any adjustment to the Exercise Price hereunder as a result of the issuance of the Convertible Securities. The Company shall calculate, using standard commercial valuation methods appropriate for valuing such assets, the fair market value of any consideration other than cash or securities; provided, however, that if the holder hereof does not agree to such fair market value calculation within three business days after receipt thereof from the Company, then such fair market value will be determined in good faith by an investment banker or other appropriate expert of national reputation selected by the Company and reasonably acceptable to the holder hereof, with the costs of such appraisal to be borne by the Company. (v) Issuances Pursuant to Existing Securities. If the Company, at any time during the Exercise Period, issues (or becomes obligated to issue) shares of Common Stock pursuant to any antidilution or similar adjustments contained in a security or instrument outstanding as of the date hereof but not included on Schedule 3(d) of the Securities Purchase Agreement, then all shares of Common Stock so issued shall be deemed to have been issued for no consideration. If the Company, at any time during the Exercise Period, issues (or becomes obligated to issue) shares of Common Stock pursuant to any antidilution or similar adjustments contained in a security or instrument included on Schedule 3(d) of the Securities Purchase Agreement as a result of the issuance of the Preferred Shares or Warrants and the number of shares that the Company issues (or is obligated to issue) as a result of such initial issuance exceeds the amount specified on Schedule 3(d) of the Securities Purchase Agreement, such excess shares shall be deemed to have been issued for no consideration. (vi) Exceptions to Adjustment of Exercise Price. No adjustment to the Exercise Price will be made (i) except as otherwise provided in Section 4(b)(v), upon the exercise of any warrants, options or convertible securities issued and outstanding on the Issue Date that are set forth on Schedule 3(d) of the Securities Purchase Agreement in accordance with the terms of such securities as of such date; (ii) upon the grant or exercise of any stock or options which may hereafter be granted to or exercised by any employee, director or consultant under any employee benefit plan of the Company now existing or to be implemented in the future, so long as the issuance of such stock or options is approved by a majority of the Board of Directors of the Company or a majority of the members of a committee of non-employee directors established for such purpose; (iii) upon the issuance of any shares of Series A Preferred Stock or Warrants issued or issuable in accordance with the terms of the Securities Purchase Agreement; (iv) upon conversion of the Series A Preferred Stock or exercise of the Warrants, (v) the issuance of securities in connection with strategic business partnerships or joint ventures (including, without limitation, such transactions with major pharmaceutical lab or life sciences companies), the primary purpose of which, in the reasonable judgment of the Board of Directors, is not to raise additional capital, or (vii) the issuance of securities pursuant to any equipment financing from a bank or similar financial or lending institution approved by the Board of Directors. 8 9 (c) Subdivision or Combination of Common Stock. If the Company, at any time during the Exercise Period, subdivides (by any stock split, stock dividend, recapitalization, reorganization, reclassification or otherwise) its shares of Common Stock into a greater number of shares, then, after the date of record for effecting such subdivision, the Exercise Price in effect immediately prior to such subdivision will be proportionately reduced. If the Company, at any time during the Exercise Period, combines (by reverse stock split, recapitalization, reorganization, reclassification or otherwise) its shares of Common Stock into a smaller number of shares, then, after the date of record for effecting such combination, the Exercise Price in effect immediately prior to such combination will be proportionately increased. (d) Adjustment in Number of Shares. Upon each adjustment of the Exercise Price pursuant to the provisions of this Section 4, the number of shares of Common Stock issuable upon exercise of this Warrant at each such Exercise Price shall be adjusted by multiplying a number equal to the Exercise Price in effect immediately prior to such adjustment by the number of shares of Common Stock issuable upon exercise of this Warrant at such Exercise Price immediately prior to such adjustment and dividing the product so obtained by the adjusted Exercise Price. (e) Consolidation, Merger or Sale. In case of any consolidation of the Company with, or merger of the Company into, any other corporation, or in case of any sale or conveyance of all or substantially all of the assets of the Company other than in connection with a plan of complete liquidation of the Company at any time during the Exercise Period, then as a condition of such consolidation, merger or sale or conveyance, adequate provision will be made whereby the holder hereof will have the right to acquire and receive upon exercise of this Warrant in lieu of the shares of Common Stock immediately theretofore acquirable upon the exercise of this Warrant, such shares of stock, securities, cash or assets as may be issued or payable with respect to or in exchange for the number of shares of Common Stock immediately theretofore acquirable and receivable upon exercise of this Warrant had such consolidation, merger or sale or conveyance not taken place. In any such case, the Company will make appropriate provision to insure that the provisions of this Section 4 hereof will thereafter be applicable as nearly as may be in relation to any shares of stock or securities thereafter deliverable upon the exercise of this Warrant. The Company will not effect any consolidation, merger or sale or conveyance unless prior to the consummation thereof, the successor corporation (if other than the Company) assumes by written instrument the obligations under this Warrant and the obligations to deliver to the holder hereof such shares of stock, securities or assets as, in accordance with the foregoing provisions, the holder may be entitled to acquire. Notwithstanding the foregoing, in the event of any consolidation of the Company with, or merger of the Company into, any other corporation, or the sale or conveyance of all or substantially all of the assets of the Company, at any time during the Exercise Period, the holder hereof shall, at its option, have the right to receive, in connection with such transaction, cash consideration equal to the fair market value of this Warrant as determined in accordance with customary valuation methodology used in the investment banking industry. (f) Distribution of Assets. In case the Company shall declare or make any distribution of its assets (or rights to acquire its assets) to holders of Common Stock as a partial liquidating dividend, stock repurchase by way of return of capital or otherwise (including any dividend or distribution to the Company's stockholders of cash or shares (or rights to acquire shares) 9 10 of capital stock of a subsidiary) (a "DISTRIBUTION"), at any time during the Exercise Period, then the holder hereof shall be entitled upon exercise of this Warrant for the purchase of any or all of the shares of Common Stock subject hereto, to receive the amount of such assets (or rights) which would have been payable to the holder had such holder been the holder of such shares of Common Stock on the record date for the determination of stockholders entitled to such Distribution. If the Company distributes rights, warrants, options or any other form of convertible securities and the right to exercise or convert such securities would expire in accordance with their terms prior to the expiration of the Exercise Period, then the terms of such securities shall provide that such exercise or convertibility right shall remain in effect until 30 days after the date the holder hereof receives such securities pursuant to the exercise hereof. (g) Notice of Adjustment. Upon the occurrence of any event which requires any adjustment of the Exercise Price, then, and in each such case, the Company shall give notice thereof to the holder hereof, which notice shall state the Exercise Price resulting from such adjustment and the increase or decrease in the number of Warrant Shares purchasable at such price upon exercise, setting forth in reasonable detail the method of calculation and the facts upon which such calculation is based. Such calculation shall be certified by the chief financial officer of the Company. (h) Minimum Adjustment of Exercise Price. No adjustment of the Exercise Price shall be made in an amount of less than $.01, but any such lesser adjustment shall be carried forward and shall be made at the time and together with the next subsequent adjustment which, together with any adjustments so carried forward, shall amount to not less than $.01. (i) No Fractional Shares. No fractional shares of Common Stock are to be issued upon the exercise of this Warrant, but the Company shall pay a cash adjustment in respect of any fractional share which would otherwise be issuable in an amount equal to the same fraction of the Market Price of a share of Common Stock on the date of such exercise. (j) Other Notices. In case at any time: (i) the Company shall declare any dividend upon the Common Stock payable in shares of stock of any class or make any other distribution (other than dividends or distributions payable in cash out of retained earnings consistent with the Company's past practices with respect to declaring dividends and making distributions) to the holders of the Common Stock; (ii) the Company shall offer for subscription pro rata to the holders of the Common Stock any additional shares of stock of any class or other rights; (iii) there shall be any capital reorganization of the Company, or reclassification of the Common Stock, or consolidation or merger of the Company with or into, or sale of all or substantially all of its assets to, another corporation or entity; or (iv) there shall be a voluntary or involuntary dissolution, liquidation or winding-up of the Company; 10 11 then, in each such case, the Company shall give to the holder of this Warrant (a) notice of the date or estimated date on which the books of the Company shall close or a record shall be taken for determining the holders of Common Stock entitled to receive any such dividend, distribution, or subscription rights or for determining the holders of Common Stock entitled to vote in respect of any such reorganization, reclassification, consolidation, merger, sale, dissolution, liquidation or winding-up and (b) in the case of any such reorganization, reclassification, consolidation, merger, sale, dissolution, liquidation or winding-up, notice of the date (or, if not then known, a reasonable estimate thereof by the Company) when the same shall take place. Such notice shall also specify the date on which the holders of Common Stock shall be entitled to receive such dividend, distribution, or subscription rights or to exchange their Common Stock for stock or other securities or property deliverable upon such reorganization, reclassification, consolidation, merger, sale, dissolution, liquidation, or winding-up, as the case may be. Such notice shall be given at least fifteen (15) days prior to the record date or the date on which the Company's books are closed in respect thereto. Failure to give any such notice or any defect therein shall not affect the validity of the proceedings referred to in clauses (i), (ii), (iii) and (iv) above. Notwithstanding the foregoing, the Company shall publicly disclose the substance of any notice delivered hereunder prior to delivery of such notice to the holder hereof. (k) Certain Events. If, at any time during the Exercise Period, any event occurs of the type contemplated by the adjustment provisions of this Section 4 but not expressly provided for by such provisions, the Company will give notice of such event as provided in Section 4(g) hereof, and an appropriate adjustment in the Exercise Price and the number of shares of Common Stock acquirable upon exercise of this Warrant at each such Exercise Price shall be made so that the rights of the holder shall be neither enhanced nor diminished by such event. (l) Certain Definitions. (i) "MARKET PRICE," as of any date, (i) means the average of the closing sales prices for the shares of Common Stock on the Nasdaq National Market or other trading market where such security is listed or traded as reported by Bloomberg Financial Markets (or a comparable reporting service of national reputation selected by the Company and reasonably acceptable to the holders if Bloomberg Financial Markets is not then reporting sales prices of such security)(collectively, "BLOOMBERG") for the ten (10) consecutive trading days immediately preceding such date, or (ii) if the Nasdaq National Market is not the principal trading market for the shares of Common Stock, the average of the reported sales prices reported by Bloomberg on the principal trading market for the Common Stock during the same period, or, if there is no sales price for such period, the last sales price reported by Bloomberg for such period, or (iii) if the foregoing do not apply, the last sales price of such security in the over-the-counter market on the pink sheets or bulletin board for such security as reported by Bloomberg, or if no sales price is so reported for such security, the last bid price of such security as reported by Bloomberg, or (iv) if market value cannot be calculated as of such date on any of the foregoing bases, the Market Price shall be the average fair market value as reasonably determined by an investment banking firm selected by the Company and reasonably acceptable to the holder, with the costs of the appraisal to be borne by the Company. The manner of determining the Market Price of the Common Stock set forth in the foregoing definition 11 12 shall apply with respect to any other security in respect of which a determination as to market value must be made hereunder. (ii) "COMMON STOCK," for purposes of this Section 4, includes the Common Stock and any additional class of stock of the Company having no preference as to dividends or distributions on liquidation, provided that the shares purchasable pursuant to this Warrant shall include only Common Stock in respect of which this Warrant is exercisable, or shares resulting from any subdivision or combination of such Common Stock, or in the case of any reorganization, reclassification, consolidation, merger, or sale of the character referred to in Section 4(e) hereof, the stock or other securities or property provided for in such Section. (iii) "MEASUREMENT DATE" means (i) for purposes of any private offering of securities under Section 4(2) of the Securities Act of 1933, as amended, the date that the Company enters into legally binding definitive agreements for the issuance and sale of such securities and (ii) for purposes of any other issuance of securities, the date of issuance thereof. 5. Issue Tax. The issuance of certificates for Warrant Shares upon the exercise of this Warrant shall be made without charge to the holder of this Warrant or such shares for any issuance tax or other costs in respect thereof, provided that the Company shall not be required to pay any tax which may be payable in respect of any transfer involved in the issuance and delivery of any certificate in a name other than the holder of this Warrant. 6. No Rights or Liabilities as a Stockholder. This Warrant shall not entitle the holder hereof to any voting rights or other rights as a stockholder of the Company. No provision of this Warrant, in the absence of affirmative action by the holder hereof to purchase Warrant Shares, and no mere enumeration herein of the rights or privileges of the holder hereof, shall give rise to any liability of such holder for the Exercise Price or as a stockholder of the Company, whether such liability is asserted by the Company or by creditors of the Company. 7. Transfer, Exchange and Replacement of Warrant. (a) Restriction on Transfer. This Warrant and the rights granted to the holder hereof are transferable, in whole or in part, upon surrender of this Warrant, together with a properly executed assignment in the form attached hereto, at the office or agency of the Company referred to in Section 7(e) below, provided, however, that any transfer or assignment shall be subject to the conditions set forth in Sections 7(f) and (g) hereof and to the provisions of Sections 2(f) and 2(g) of the Securities Purchase Agreement.

Notwithstanding anything to the contrary contained herein, the registration rights described in Section 8 hereof are assignable only in accordance with the provisions of the Registration Rights Agreement. 12 13 (b) Warrant Exchangeable for Different Denominations. This Warrant is exchangeable, upon the surrender hereof by the holder hereof at the office or agency of the Company referred to in Section 7(e) below, for new Warrants of like tenor of different denominations representing in the aggregate the right to purchase the number of shares of Common Stock which may be purchased hereunder, each of such new Warrants to represent the right to purchase such number of shares (at the Exercise Price therefor) as shall be designated by the holder hereof at the time of such surrender. (c) Replacement of Warrant. Upon receipt of evidence reasonably satisfactory to the Company of the loss, theft, destruction, or mutilation of this Warrant and, in the case of any such loss, theft, or destruction, upon delivery of an indemnity agreement reasonably satisfactory in form and amount to the Company, or, in the case of any such mutilation, upon surrender and cancellation of this Warrant, the Company, at its expense, will execute and deliver, in lieu thereof, a new Warrant of like tenor. (d) Cancellation; Payment of Expenses. Upon the surrender of this Warrant in connection with any transfer, exchange, or replacement as provided in this Section 7, this Warrant shall be promptly canceled by the Company. The Company shall pay all taxes (other than securities transfer taxes) and all other expenses (other than legal expenses, if any, incurred by the Holder or transferees) and charges payable in connection with the preparation, execution, and delivery of Warrants pursuant to this Section 7. (e) Warrant Register. The Company shall maintain, at its principal executive offices (or such other office or agency of the Company as it may designate by notice to the holder hereof), a register for this Warrant, in which the Company shall record the name and address of the person in whose name this Warrant has been issued, as well as the name and address of each transferee and each prior owner of this Warrant. (f) Exercise or Transfer Without Registration. If, at the time of the surrender of this Warrant in connection with any exercise, transfer, or exchange of this Warrant, this Warrant (or, in the case of any exercise, the Warrant Shares issuable hereunder), shall not be registered under the Securities Act and under applicable state securities or blue sky laws, the Company may require, as a condition of allowing such exercise, transfer, or exchange, (i) that the holder or transferee of this Warrant, as the case may be, furnish to the Company a written opinion of counsel (which opinion shall be in form, substance and scope customary for opinions of counsel in comparable transactions) to the effect that such exercise, transfer, or exchange may be made without registration under the Securities Act and under applicable state securities or blue sky laws (the cost of which shall be borne by the Company if the Company's counsel renders such an opinion and up to $500 of such cost shall be borne by the Company if the holder's counsel is requested to render such opinion), (ii) that the holder or transferee execute and deliver to the Company an investment letter in form and substance acceptable to the Company and (iii) that the transferee be an "ACCREDITED INVESTOR" as defined in Rule 501(a) promulgated under the Securities Act; provided that no such opinion, letter, or status as an "accredited investor" shall be required in connection with a transfer pursuant to Rule 144 under the Securities Act. 13 14 (g) Additional Restrictions on Exercise or Transfer. In no event shall the holder hereof have the right to exercise any portion of this Warrant for shares of Common Stock or to dispose of any portion of this Warrant to the extent that such right to effect such exercise or disposition would result in the holder or any of its affiliates beneficially owning more than 4.99% of the outstanding shares of Common Stock. For purposes of this Section 7(g), beneficial ownership shall be determined in accordance with Section 13(d) of the Securities Exchange Act of 1934, as amended, and Regulation 13D-G thereunder. The restriction contained in this Section 7(g) may not be altered, amended, deleted or changed in any manner whatsoever unless the holders of a majority of the outstanding shares of Common Stock and the holder hereof shall approve, in writing, such alteration, amendment, deletion or change. In addition, in no event will the Company issue a number of shares of Common Stock upon exercise of this Warrant in excess of such holder's pro rata Cap Amount (as defined in the Certificate of Designation). In the event the Company is prohibited from issuing such shares upon exercise of this Warrant due to the Cap Amount, the holder shall have the remedies set forth in the Certificate of Designation with respect to the shares that cannot be issued. 8. Registration Rights. The initial holder of this Warrant (and certain assignees thereof) is entitled to the benefit of such registration rights in respect of the Warrant Shares as are set forth in the Registration Rights Agreement, including the right to assign such rights to certain assignees, as set forth therein. 9. Notices. Any notices required or permitted to be given under the terms of this Warrant shall be sent by certified or registered mail (return receipt requested) or delivered personally or by courier or by confirmed telecopy, and shall be effective five days after being placed in the mail, if mailed, or upon receipt or refusal of receipt, if delivered personally or by courier, or by confirmed telecopy, in each case addressed to a party. The addresses for such communications shall be: If to the Company: ViroLogic, Inc. 270 East Grand Avenue South San Francisco, California 94080 Telephone: (650) 635-1100 Attn: Chief Executive Officer with a copy simultaneously transmitted by like means to: Cooley Godward LLP 4365 Executive Drive, Suite 1100 San Diego, California 92121 Telephone: (858) 550-6000 Attn: Christopher J.

If to the holder, at such address as such holder shall have provided in writing to the Company, or at such other address as such holder furnishes by notice given in accordance with this Section 9. 14 15 10. Governing Law; Jurisdiction. This Warrant shall be governed by and construed in accordance with the laws of the State of Delaware. The Company irrevocably consents to the jurisdiction of the United States federal courts and state courts located in the State of Delaware in any suit or proceeding based on or arising under this Warrant and irrevocably agrees that all claims in respect of such suit or proceeding may be determined in such courts. The Company irrevocably waives any objection to the laying of venue and the defense of an inconvenient forum to the maintenance of such suit or proceeding. The Company further agrees that service of process upon the Company mailed by certified or registered mail shall be deemed in every respect effective service of process upon the Company in any such suit or proceeding. Nothing herein shall affect the holder's right to serve process in any other manner permitted by law. The Company agrees that a final non-appealable judgment in any such suit or proceeding shall be conclusive and may be enforced in other jurisdictions by suit on such judgment or in any other lawful manner. 11. Miscellaneous. (a) Amendments. Except as provided in Section 7(g) hereof, this Warrant and any provision hereof may only be amended by an instrument in writing signed by the Company and the holder hereof. (b) Descriptive Headings. The descriptive headings of the several Sections of this Warrant are inserted for purposes of reference only, and shall not affect the meaning or construction of any of the provisions hereof. (c) Cashless Exercise. This Warrant may be exercised at any time after the first anniversary of the Issue Date and before the expiration of the Exercise Period by presentation and surrender of this Warrant to the Company at its principal executive offices with a written notice of the holder's intention to effect a cashless exercise, including a calculation of the number of shares of Common Stock to be issued upon such exercise in accordance with the terms hereof (a "CASHLESS EXERCISE"). In the event of a Cashless Exercise, in lieu of paying the Exercise Price in cash, the holder shall surrender this Warrant for that number of shares of Common Stock determined by multiplying the number of Warrant Shares to which it would otherwise be entitled by a fraction, the numerator of which shall be the difference between the then current Market Price of a share of the Common Stock on the date of exercise and the Exercise Price, and the denominator of which shall be the then current Market Price per share of Common Stock. (d) Trading Day. For purposes of this Warrant, the term "trading day" means any day on which the principal United States securities exchange or trading market where the Common Stock is then listed is open for trading. (e) Redemption of Warrant by Company. (i) Provided that (x) all shares of Common Stock issuable upon exercise of the Warrants are then (A) authorized and reserved for issuance, (B) registered under the Securities Act of 1933, as amended, for resale by the holders of the Warrants, (C) eligible to be traded on the Nasdaq National Market or its successor, (y) all of the Required Conditions (as defined in the Certificate of Designation) are satisfied, and (z) the Closing Bid Price (as defined in the Certificate 15 16 of Designation) of the Common Stock is greater than 200% of the Exercise Price as in effect on the Issue Date for twenty (20) or more consecutive trading days immediately prior to the delivery by the Company of a Redemption Notice (as defined below), the Company may elect, upon delivery of at least twenty (20) days' prior written notice (the "REDEMPTION NOTICE") to the holder hereof, to redeem all or a portion of the Warrants for a redemption amount equal to the number of Warrant Shares issuable upon the exercise of all or a portion of this Warrant that is being redeemed multiplied by $.10 (the "REDEMPTION AMOUNT"). For example, if the Company elects to redeem Warrants exercisable for 10,000 shares of Common Stock, the Company will pay the holder a Redemption Amount equal to $1,000. In the event the Company elects to redeem only some of the outstanding Warrants pursuant to this Section 11(e), such Warrants shall be redeemed pro rata among all the holders of the Warrants based upon the percentage of Warrants held by such holders against the total outstanding Warrants. Notwithstanding the foregoing, the Company may only redeem Warrants exercisable for no more than 400,000 shares of Common Stock in any 30 day period. (ii) The Company may not deliver a Notice of Redemption unless on or prior to the date of delivery of a Notice of Redemption, the Company shall have segregated on the books and records of the Company an amount of cash sufficient to pay all amounts to which holders of the Warrants that are being redeemed are entitled pursuant to Section 11(e)(i). Any Notice of Redemption delivered shall be irrevocable and shall be accompanied by a statement executed by a duly authorized officer of the Company. (iii) The Redemption Amount shall be paid to the holder within three (3) business days of the date of redemption set forth in the Notice of Redemption; provided, however, that the Company shall not be obligated to deliver any portion of the Redemption Amount until either this Warrant is delivered to the Company or the holder notifies the Company that the Warrant has been lost, stolen or destroyed and delivers the documentation in accordance with Section 7(c) hereof. In the event only a portion of this Warrant is being redeemed, the Company shall issue , at its expense, a new Warrant representing the number of shares with respect to which this Warrant shall not then have been redeemed or exercised. (iv) Notwithstanding the delivery of a Redemption Notice, the holder may exercise all or a portion of this Warrant subject to such Redemption Notice by the delivery prior to the date of redemption set forth in such notice of an Exercise Agreement pursuant to the procedures set forth in Section 1. (f) Indemnification by Company. (i) The Company shall hold harmless and indemnify the holder of this Warrant from and against, and shall compensate and reimburse such holder for, any damages which are directly or indirectly suffered or incurred by such holder or to which such holder may otherwise become subject (regardless of whether or not such damages relate to any third-party claim) and which arise from or as a result of, or are directly or indirectly connected with any breach of any of the Company's covenants set forth herein. 16 17 (ii) In the event of the assertion or commencement by any person of any claim or legal proceeding with respect to which the holder may have indemnification rights pursuant to this Section 11(f)(i), the holder shall promptly notify the Company thereof in writing, but the failure to so notify the Company will not limit the holder's rights to indemnification hereunder, except to the extent the Company demonstrates that the defense of such action is prejudiced by the failure to so give such notice. 17 18 IN WITNESS WHEREOF, the Company has caused this Warrant to be signed by its duly authorized officer.
