CRYOPORT, INC.

COMMON STOCK PURCHASE WARRANT

1. Issuance; Certain Definitions. In consideration of good and valuable consideration, the receipt of which is hereby acknowledged by CryoPort, Inc., a Nevada corporation (the “Company”), [INVESTOR] or registered assigns (the “Holder”) is hereby granted the right to purchase at any time until 5:00 p.m., New York City time, on February __, 2016, ______________________ (_____) fully paid and nonassessable shares of the Company’s Common Stock, $0.001 par value per share (the “Common Stock”), at an initial exercise price per share (the “Exercise Price”) of $0.77 per share, subject to further adjustment as set forth herein. This Warrant is being issued pursuant to that certain Securities Purchase Agreement, as amended, and Registration Rights Agreement, each by and between the Company and the Holder, and each of even date herewith.

2. Exercise of Warrants.

     2.1 Method of Exercise.

(a)

This Warrant is exercisable in whole or in part at any time and from time to time. Such exercise shall be effectuated by submitting to the Company (either by delivery to the Company or by facsimile transmission as provided in Section 8 hereof) a completed and duly executed Notice of Exercise (substantially in the form attached to this Warrant) as provided in this paragraph. The date such Notice of Exercise is faxed to the Company shall be the “Exercise Date,” provided that the Holder of this Warrant tenders this Warrant Certificate to the Company within five (5) business days thereafter. The Notice of Exercise shall be executed by the Holder of this Warrant and shall indicate the number of shares then being purchased pursuant to such exercise. Upon surrender of this Warrant Certificate, together with appropriate payment of the Exercise Price for the shares of Common Stock purchased, the Holder shall be entitled to receive a certificate or certificates for the shares of Common Stock so purchased. The Exercise Price shall be paid cash pursuant to Section 2.1(b) below.

	(b)		The Exercise Price per share of Common Stock for the shares then being exercised shall be payable in cash or by certified or official bank check. Notwithstanding the foregoing, if, at any time following the date which is six (6) months from the date hereof, the Company does not have an effective registration statement covering the resale of the shares issuable upon exercise of this Warrant at the time a Notice of Exercise is delivered to the Company, the Holder may elect to exercise on “cashless” basis. Upon such election to effect a “cashless exercise”, the Holder shall thereby be entitled to receive a number of shares of Common Stock equal to (x) the excess of the Current Market Value (as defined below) over the total cash exercise price of the portion of the Warrant then being exercised, divided by (y) the Market Price of the Common Stock as of the trading day immediately prior to the Exercise Date. For the purposes of this Warrant, the terms (Q) “Current Market Value” shall be an amount equal to the Market Price of the Common Stock as of the trading day immediately prior to the Exercise Date, multiplied by the number of shares of Common Stock specified in such Notice of Exercise Form, and (R) “Market Price of the Common Stock” shall be the closing price of the Common Stock as reported by the OTC Bulletin Board, or if listed on a national securities exchange or quoted on an automated quotation service, such national securities exchange or automated quotation service, for the relevant date. If the Common Stock is not then listed on a national stock exchange or quoted on the OTC Bulletin Board or such other quotation system or association, the fair market value of one share of Common Stock as of the date of determination, as determined in good faith by the Board of Directors of the Company and the Holder. If the Common Stock is not then listed on a national securities exchange, the OTC Bulletin Board or such other quotation system or association, the Board of Directors of the Company shall respond promptly, in writing, to an inquiry by the Holder prior to the exercise hereunder as to the fair market value of a share of Common Stock as determined by the Board of Directors of the Company. In the event that the Board of Directors of the Company and the Holder are unable to agree upon the fair market value, the Company and the Holder shall jointly select an appraiser, who is experienced in such matters. The decision of such appraiser shall be final and conclusive, and the cost of such appraiser shall be borne equally by the Company and the Holder. Such adjustment shall be made successively whenever such a payment date is fixed.
	(c)		The Holder shall be deemed to be the holder of the shares issuable to it in accordance with the provisions of this Section 2.1 on the Exercise Date

     2.2 Limitation on Exercise. Notwithstanding the provisions of this Warrant or the Securities Purchase Agreement, in no event (except (i) as specifically provided in this Warrant as an exception to this provision, (ii) while there is outstanding a tender offer for any or all of the shares of the Company’s Common Stock, or (iii) at the Holder’s option, on at least sixty-five (65) days’ advance written notice from the Holder) shall the Holder be entitled to exercise this Warrant, or shall the Company have the obligation to issue shares upon such exercise of all or any portion of this Warrant to the extent that, after such exercise the sum of (1) the number of shares of Common Stock beneficially owned by the Holder and its affiliates (other than shares of

Common Stock which may be deemed beneficially owned through the ownership of the unexercised portion of the Warrants or other rights to purchase Common Stock), and (2) the number of shares of Common Stock issuable upon the exercise of the Warrants with respect to which the determination of this proviso is being made, would result in beneficial ownership by the Holder and its affiliates of more than 9.99% of the outstanding shares of Common Stock (after taking into account the shares to be issued to the Holder upon such exercise). For purposes of the proviso to the immediately preceding sentence, beneficial ownership shall be determined in accordance with Section 13(d) of the Securities Exchange Act of 1934, as amended (the “1934 Act”), except as otherwise provided in clause (1) of such sentence. The Holder, by its acceptance of this Warrant, further agrees that if the Holder transfers or assigns any of the Warrants, such assignment shall be made subject to the transferee’s or assignee’s specific agreement to be bound by the provisions of this Section 2.2 as if such transferee or assignee were the original Holder hereof.

3. Reservation of Shares. The Company hereby agrees that at all times during the term of this Warrant there shall be reserved for issuance upon exercise of this Warrant such number of shares of its Common Stock as shall be required for issuance upon exercise of this Warrant (the “Warrant Shares”). The Company agrees that all Warrant Shares issued upon due exercise of the Warrant shall be, at the time of delivery of the certificates for such Warrant Shares, duly authorized, validly issued, fully paid and non-assessable shares of Common Stock of the Company.

4. Mutilation or Loss of Warrant. Upon receipt by the Company of evidence satisfactory to it of the loss, theft, destruction or mutilation of this Warrant, and (in the case of loss, theft or destruction) receipt of reasonably satisfactory indemnification, and (in the case of mutilation) upon surrender and cancellation of this Warrant, the Company will execute and deliver a duplicate Warrant and any such lost, stolen, destroyed or mutilated Warrant shall thereupon become void.

5. Rights of the Holder. The Holder shall not, by virtue hereof, be entitled to any rights of a stockholder in the Company, either at law or equity, and the rights of the Holder are limited to those expressed in this Warrant and are not enforceable against the Company except to the extent set forth herein.

6. Protection Against Dilution and Other Adjustments.

     6.1 Adjustment Mechanism. If an adjustment of the Exercise Price is required pursuant to this Section 6, the Holder shall be entitled to purchase such number of additional shares of Common Stock as will cause (i) the total number of shares of Common Stock Holder is entitled to purchase pursuant to this Warrant, multiplied by (ii) the adjusted Exercise Price per share, to equal (iii) the dollar amount of the total number of shares of Common Stock Holder is entitled to purchase before adjustment multiplied by the total Exercise Price immediately before adjustment.

     6.2 Dividends; Distributions. If the Company shall, at any time or from time to time while this Warrant is outstanding, pay a dividend or make a distribution on its Common Stock in shares of Common Stock, subdivide its outstanding shares of Common Stock into a greater

number of shares or combine its outstanding shares of Common Stock into a smaller number of shares or issue by reclassification of its outstanding shares of Common Stock any shares of its capital stock (including any such reclassification in connection with a consolidation or merger in which the Company is the continuing corporation), then (i) the Exercise Price in effect immediately prior to the date on which such change shall become effective shall be adjusted by multiplying such Exercise Price by a fraction, the numerator of which shall be the number of shares of Common Stock outstanding immediately prior to such change and the denominator of which shall be the number of shares of Common Stock outstanding immediately after giving effect to such change and (ii) the number of Warrant Shares purchasable upon exercise of this Warrant shall be adjusted by multiplying the number of Warrant Shares purchasable upon exercise of this Warrant immediately prior to the date on which such change shall become effective by a fraction, the numerator of which is shall be the Exercise Price in effect immediately prior to the date on which such change shall become effective and the denominator of which shall be the Exercise Price in effect immediately after giving effect to such change, calculated in accordance with clause (i) above. Such adjustments shall be made successively whenever any event listed above shall occur.

     6.3. Reorganization; Reclassification; Merger; Consolidation. If any capital reorganization, reclassification of the capital stock of the Company, consolidation or merger of the Company with another corporation in which the Company is not the survivor, or sale, transfer or other disposition of all or substantially all of the Company’s assets to another corporation shall be effected, then, as a condition of such reorganization, reclassification, consolidation, merger, sale, transfer or other disposition, lawful and adequate provision shall be made whereby each Holder shall thereafter have the right to purchase and receive upon the basis and upon the terms and conditions herein specified and in lieu of the Warrant Shares immediately theretofore issuable upon exercise of the Warrant, such shares of stock, securities or assets as would have been issuable or payable with respect to or in exchange for a number of Warrant Shares equal to the number of Warrant Shares immediately theretofore issuable upon exercise of the Warrant, had such reorganization, reclassification, consolidation, merger, sale, transfer or other disposition not taken place, and in any such case appropriate provision shall be made with respect to the rights and interests of each Holder to the end that the provisions hereof (including, without limitation, provision for adjustment of the Exercise Price) shall thereafter be applicable, as nearly equivalent as may be practicable in relation to any shares of stock, securities or assets thereafter deliverable upon the exercise hereof. The Company shall not effect any such consolidation, merger, sale, transfer or other disposition unless prior to or simultaneously with the consummation thereof the successor corporation (if other than the Company) resulting from such consolidation or merger, or the corporation purchasing or otherwise acquiring such assets or other appropriate corporation or entity shall assume the obligation to deliver to the Holder, at the last address of the Holder appearing on the books of the Company, such shares of stock, securities or assets as, in accordance with the foregoing provisions, the Holder may be entitled to purchase, and the other obligations under this Warrant. The provisions of this Section 6.3 shall similarly apply to successive reorganizations, reclassifications, consolidations, mergers, sales, transfers or other dispositions.

     6.4 Distributions to Holders of Common Stock. In case the Company shall fix a payment date for the making of a distribution to all holders of Common Stock (including any such distribution made in connection with a consolidation or merger in which the Company is

the continuing corporation) of evidences of indebtedness or assets (other than cash dividends or cash distributions payable out of consolidated earnings or earned surplus or dividends or distributions referred to in Section 6.2, or subscription rights or warrants), the Exercise Price to be in effect after such payment date shall be determined by multiplying the Exercise Price in effect immediately prior to such payment date by a fraction, the numerator of which shall be the total number of shares of Common Stock outstanding multiplied by the Current Market Value per share of Common Stock immediately prior to such payment date, less the fair market value (as determined by the Company’s Board of Directors in good faith) of said assets or evidences of indebtedness so distributed, or of such subscription rights or warrants, and the denominator of which shall be the total number of shares of Common Stock outstanding multiplied by such Current Market Value per share of Common Stock immediately prior to such payment date.

7. Transfer to Comply with the Securities Act; Registration Rights.

     7.1 Transfer. This Warrant has not been registered under the Securities Act of 1933, as amended, (the “Act”) and has been issued to the Holder for investment and not with a view to the distribution of either the Warrant or the Warrant Shares. Except for transfers to officers, employees and affiliates of the Holder, neither this Warrant nor any of the Warrant Shares or any other security issued or issuable upon exercise of this Warrant may be sold, transferred, pledged or hypothecated in the absence of an effective registration statement under the Act relating to such security or an opinion of counsel satisfactory to the Company that registration is not required under the Act. Each certificate for the Warrant, the Warrant Shares and any other security issued or issuable upon exercise of this Warrant shall contain a legend on the face thereof, in form and substance satisfactory to counsel for the Company, setting forth the restrictions on transfer contained in this Section.
