WARRANT TO PURCHASE COMMON STOCK

Warrant No.:

Number of Shares of Common Stock:171,568 Date of Issuance: February 3, 2010 ("Issuance Date")

     Raser Technologies, Inc., a Delaware corporation (the "Company"), hereby certifies that, for good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, Jason Diamond, as agent (the "Agent"), for the benefit of CapStone Investments, as the registered holder hereof or its permitted assigns (the "Holder"), is entitled, on behalf of, and for the sole and exclusive benefit of, the Holder, subject to the terms set forth below, to purchase from the Company, at the Exercise Price (as defined below) then in effect, upon surrender of this Warrant to Purchase Common Stock (including any Warrants to Purchase Common Stock issued in exchange, transfer or replacement hereof, the "Warrant"), at any time or times on or after the date that is 181 days after date hereof (the "Exercisability Date"), but not after 11:59 p.m., New York time, on the Expiration Date (as defined below), 171,568 fully paid nonassessable shares of Common Stock (as defined below) (the "Warrant Shares"). Except as otherwise defined herein, capitalized terms in this Warrant shall have the meanings set forth in Section 15. This Warrant is the Warrant to purchase Common Stock (this "Warrant') issued pursuant to that certain Underwriting Agreement, dated February 3, 2010, by and between the Company and the Holder (the "Capstone Agreement").

Warrant may be exercised by the Agent on behalf of, and for the sole and exclusive benefit of, the Holder, on any day on or after the Exercisability Date, in whole or in part, by delivery of a written notice, in the form attached hereto as Exhibit A (the "Exercise Notice"), of the Agent's election to exercise this Warrant on behalf of, and for the sole and exclusive benefit of, the Holder. The Original Warrant is not required to be delivered in order to effect an exercise hereunder, but it shall be delivered within five (5) days thereafter. Execution and delivery of the Exercise Notice with respect to less than all of the Warrant Shares shall have the same effect as cancellation of the original Warrant and issuance of a new Warrant evidencing the right to purchase the remaining number of Warrant Shares. On or before the first (1st) Business Day following the date on which the Company has received the Exercise Notice, the Company shall transmit by facsimile an acknowledgment of confirmation of receipt of the Exercise Notice to the Agent and the Holder and Interwest Transfer Company, the Company's transfer Agent ("Transfer Agent"). On or before the third (3^rd) Business Day following the date on which the Company has received the Exercise Notice (the "Share Delivery Date"), the Company shall (X) provided that the Transfer Agent is participating in The Depository Trust Company ("DTC") Fast Automated Securities Transfer Program, upon the request of the Agent or the Holder, credit such aggregate number of Warrant Shares to which the Agent is entitled pursuant to such exercise to the Holder's or its designee's balance account with DTC through its Deposit Withdrawal Agent Commission system, or (Y) if the Transfer Agent is not participating in the DTC Fast Automated Securities Transfer Program, issue and dispatch by overnight courier to the address as specified in the Exercise Notice, a certificate, registered in the Company's share register in the name of the Holder or its designee, for the number of shares of Common Stock to which the Agent is entitled pursuant to such exercise. Upon delivery of the Exercise Notice, the Holder shall be deemed for all corporate purposes to have become the holder of record of the Warrant Shares with respect to which this Warrant has been exercised, irrespective of the date such Warrant Shares are credited to the Holder's DTC account or the date of delivery of the certificates evidencing such Warrant Shares, as the case may be. If this Warrant is submitted in connection with any exercise pursuant to this Section 1(a) and the number of Warrant Shares represented by this Warrant submitted for exercise is greater than the number of Warrant Shares being acquired upon an exercise, then the Company shall as soon as practicable and in no event later than three (3) Business Days after any exercise and at its own expense, issue a new Warrant (in accordance with Section 7(d)) representing the right to purchase the number of Warrant Shares purchasable immediately prior to such exercise under this Warrant, less the number of Warrant Shares with respect to which this Warrant is exercised. No fractional shares of Common Stock are to be issued upon the exercise of this Warrant, but rather the number of shares of Common Stock to be issued shall be rounded down to the nearest whole number. The Company shall pay any and all taxes which may be payable with respect to the issuance and delivery of Warrant Shares upon exercise of this Warrant.

     (b) Exercise Price. For purposes of this Warrant, "Exercise Price" means $1.275, subject to adjustment as provided herein.

     (c) Company's Failure to Timely Deliver Securities. If the Company shall fail for any reason or for no reason to issue to the Holder within three (3) Business Days of receipt of the Exercise Notice in compliance with the terms of this Section 1, a certificate for the

number of shares of Common Stock to which the Agent is entitled and register such shares of Common Stock on the Company's share register or to credit the Holder's balance account with DTC for such number of shares of Common Stock to which the Agent is entitled upon the exercise of this Warrant, and if on or after such Trading Day the Holder purchases (in an open market transaction or otherwise) shares of Common Stock to deliver in satisfaction of a sale by the Holder of shares of Common Stock issuable upon such exercise that the Holder anticipated receiving from the Company (a "Buy-In"), then the Company shall, within three (3) Business Days after the Holder's request and in the Holder's discretion, either (i) pay cash to the Holder in an amount equal to the Holder's total purchase price (including brokerage commissions, if any) for the shares of Common Stock so purchased (the "Buy-In Price"), at which point the Company's obligation to deliver such certificate (and to issue such Warrant Shares) shall terminate, or (ii) promptly honor its obligation to deliver to the Holder a certificate or certificates representing such Warrant Shares and pay cash to the Holder in an amount equal to the excess (if any) of the Buy-In Price over the product of (A) such number of shares of Common Stock, times (B) the Closing Bid Price on the date of exercise.

     (d) Payment of Exercise Price. The Company shall promptly, and in no case later than the Business Day immediately following such receipt, confirm receipt of an Exercise Notice via fax to the number specified in such Exercise Notice. The Exercise Price shall be delivered to the Company in immediately available funds upon receipt of such confirmation by the Company; provided, however, that the obligation to deliver the Exercise Price may be satisfied through a "cashless exercise," in which event the Company shall issue to the Holder the number of Warrant Shares determined as follows:

X = the number of Warrant Shares to be issued to the Holder.

Y = the number of Warrant Shares with respect to which this Warrant is being exercised.

A = the average of the Closing Prices for the five Trading Days immediately prior to (but not including) the Exercise Date.

     (e) Rule 144. For purposes of Rule 144(d) promulgated under the Securities Act, as in effect on the date hereof, it is intended that the Warrant Shares issued in a Cashless Exercise shall be deemed to have been acquired by the Holder, and the holding period for the Warrant Shares shall be deemed to have commenced, on the date this Warrant was originally issued pursuant to the Subscription Agreement.

     (f) Disputes. In the case of a dispute as to the determination of the Exercise Price or the arithmetic calculation of the Warrant Shares, the Company shall promptly issue to the Holder the number of Warrant Shares that are not disputed.

     (g) Beneficial Ownership. The Agent shall not have the right to exercise this Warrant, to the extent that after giving effect to such exercise, such Person (together with such Person's affiliates) would beneficially own in excess of 4.99% (the "Maximum Percentage") of the shares of Common Stock outstanding immediately after giving effect to such exercise. The Company shall be entitled to rely on the Holder's exercise notice as an indication that Holder will not, pursuant to such exercise, exceed the Maximum Percentage. For purposes of the foregoing sentence, the aggregate number of shares of Common Stock beneficially owned by such Person and its affiliates shall include the number of shares of Common Stock issuable upon exercise of this Warrant with respect to which the determination of such sentence is being made, but shall exclude shares of Common Stock which would be issuable upon (i) exercise of the remaining, unexercised portion of this Warrant beneficially owned by such Person and its affiliates and (ii) exercise or conversion of the unexercised or unconverted portion of any other securities of the Company beneficially owned by such Person and its affiliates (including, without limitation, any convertible notes or convertible preferred stock or warrants) subject to a limitation on conversion or exercise analogous to the limitation contained herein. Except as set forth in the preceding sentence, for purposes of this paragraph, beneficial ownership shall be calculated in accordance with Section 13(d) of the Securities Exchange Act of 1934, as amended. For purposes of this Warrant, in determining the number of outstanding shares of Common Stock, the Holder may rely on the number of outstanding shares of Common Stock as reflected in (1) the Company's most recent Form 10-K, Form 10-Q, Current Report on Form 8-K or other public filing with the Securities and Exchange Commission, as the case may be, (2) a more recent public announcement by the Company or (3) any other notice by the Company or the Transfer Agent setting forth the number of shares of Common Stock outstanding. For any reason at any time, upon the written or oral request of the Holder, the Company shall within two (2) Business Days confirm orally and in writing to the Holder the number of shares of Common Stock then outstanding. In any case, the number of outstanding shares of Common Stock shall be determined after giving effect to the conversion or exercise of securities of the Company, including this Warrant, by the Holder and its affiliates since the date as of which such number of outstanding shares of Common Stock was reported. By written notice to the Company, the Holder may from time to time increase or decrease the Maximum Percentage provided that (i) any such increase will not be effective until the sixty-first (61^st) day after such notice is delivered to the Company, and (ii) any such increase or decrease will apply only to the Holder. The provisions of this paragraph shall be construed and implemented in a manner otherwise than in strict conformity with the terms of this Section 1(f) to correct this paragraph (or any portion hereof) which may be defective or inconsistent with the intended beneficial ownership limitation herein contained or to make changes or supplements necessary or desirable to properly give effect to such limitation.

2. ADJUSTMENT OF EXERCISE PRICE AND NUMBER OF WARRANT

SHARES UPON SUBDIVISION OR COMBINATION OF COMMON STOCK. If the Company at any time on or after the Issuance Date subdivides (by any stock split, stock dividend, recapitalization, reorganization, scheme, arrangement or otherwise) one or more classes of its outstanding shares of Common Stock into a greater number of shares, the Exercise Price in effect immediately prior to such subdivision will be proportionately reduced and the number of Warrant Shares will be proportionately increased. If the Company at any time on or after the Issuance Date combines (by any stock split, stock dividend, recapitalization, reorganization, scheme, arrangement or otherwise) one or more classes of its outstanding shares of Common Stock into a smaller number of shares, the Exercise Price in effect immediately prior

to such combination will be proportionately increased and the number of Warrant Shares will be proportionately decreased. Any adjustment under this Section 2 shall become effective at the close of business on the date the subdivision or combination becomes effective.

     3. RIGHTS UPON DISTRIBUTION OF ASSETS. If the Company shall declare or make any dividend or other distribution of its assets (or rights to acquire its assets) to holders of shares of Common Stock, by way of return of capital or otherwise (including, without limitation, any distribution of cash, stock or other securities, property or options by way of a dividend, stock split, spin off, subdivision, reclassification, corporate rearrangement, scheme of arrangement or other similar transaction) (a "Distribution"), at any time after the issuance of this Warrant, then, in each such case:

     (a) any Exercise Price in effect immediately prior to the close of business on the record date fixed for the determination of holders of shares of Common Stock entitled to receive the Distribution shall be reduced, effective as of the close of business on such record date, to a price determined by multiplying such Exercise Price by a fraction of which (i) the numerator shall be the Closing Bid Price of the shares of Common Stock on the Trading Day immediately preceding such record date minus the value of the Distribution (as determined in good faith by the Company's Board of Directors) applicable to one share of Common Stock, and (ii) the denominator shall be the Closing Bid Price of the shares of Common Stock on the Trading Day immediately preceding such record date; and

     (b) the number of Warrant Shares shall be increased or decreased to a number of shares equal to the number of shares of Common Stock obtainable immediately prior to the close of business on the record date fixed for the determination of holders of shares of Common Stock entitled to receive the Distribution multiplied by the reciprocal of the fraction set forth in the immediately preceding paragraph (a).

     4. FUNDAMENTAL TRANSACTIONS. In connection with any Fundamental Transaction, the Company shall make appropriate provision so that this Warrant shall thereafter be exercisable for shares of the Successor Entity based upon the conversion ratio or other consideration payable in the Fundamental Transaction. The provisions of this Section shall apply similarly and equally to successive Fundamental Transactions and shall be applied without regard to any limitations on the exercise of this Warrant. Without limiting the foregoing, in connection with a Fundamental Transaction that constitutes a Change of Control, at the request of the Holder delivered before the 90th day after such Fundamental Transaction, the Company (or the Successor Entity) shall purchase this Warrant from the Holder by paying to the Holder, within five (5) Business Days after such request (or, if later, on the effective date of the Fundamental Transaction), cash in an amount equal to the Black Scholes Value of the remaining unexercised portion of this Warrant on the date of such Fundamental Transaction.

     In the event that any person becomes a Parent Entity of the Company, such person shall assume all of the obligations of the Company under this Warrant with the same effect as if such person had been named as the Company herein.

     5. NONCIRCUMVENTION. The Company hereby covenants and agrees that the Company will not, by amendment of its Certificate of Incorporation, Bylaws or through any

reorganization, transfer of assets, consolidation, merger, scheme of arrangement, 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 of this Warrant, and will at all times in good faith carry out all the provisions of this Warrant and take all action as may be required to protect the rights of the Holder. Without limiting the generality of the foregoing, the Company (i) shall 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, (ii) shall 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, and (iii) shall, so long as this Warrant is outstanding, take all action necessary to reserve and keep available out of its authorized and unissued shares of Common Stock, solely for the purpose of effecting the exercise of this Warrant, 100% of the number of shares of Common Stock issuable upon exercise of this Warrant then outstanding (without regard to any limitations on exercise).

     6. WARRANT HOLDER NOT DEEMED A STOCKHOLDER. Except as otherwise specifically provided herein, neither the Agent nor the Holder, solely in such Person's capacity as a holder of this Warrant, shall be entitled to vote or receive dividends or be deemed the holder of share capital of the Company for any purpose, nor shall anything contained in this Warrant be construed to confer upon the either, solely in such Person's capacity as the Agent or the Holder of this Warrant, as the case may be, any of the rights of a stockholder of the Company or any right to vote, give or withhold consent to any corporate action (whether any reorganization, issue of stock, reclassification of stock, consolidation, merger, conveyance or otherwise), receive notice of meetings, receive dividends or subscription rights, or otherwise, prior to the issuance to the Holder of the Warrant Shares which such Person is then entitled to receive upon the due exercise of this Warrant. In addition, nothing contained in this Warrant shall be construed as imposing any liabilities on the Agent or the Holder to purchase any securities (upon exercise of this Warrant or otherwise) or as a stockholder of the Company, whether such liabilities are asserted by the Company or by creditors of the Company.

     (a) Transfer of Warrant. If this Warrant is to be transferred, this Warrant shall be surrendered to the Company, whereupon the Company will forthwith issue and deliver upon the order of the Agent, on behalf of, and for the sole and exclusive benefit of, the Holder, a new Warrant (in accordance with Section 7(d)), registered as the Holder may request, representing the right to purchase the number of Warrant Shares being transferred by the Holder and, if less then the total number of Warrant Shares then underlying this Warrant is being transferred, a new Warrant (in accordance with Section 7(d)) to the Holder representing the right to purchase the number of Warrant Shares not being transferred.

     (b) Lost, Stolen or Mutilated Warrant. Upon receipt by the Company of evidence reasonably satisfactory to the Company of the loss, theft, destruction or mutilation of this Warrant, and, in the case of loss, theft or destruction, of any indemnification undertaking by the Holder to the Company in customary form and, in the case of mutilation, upon surrender and cancellation of this Warrant, the Company shall execute and deliver to the Holder on behalf of, and for the sole and exclusive benefit of, the Holder, a new Warrant (in accordance with Section 7(d)) representing the right to purchase the Warrant Shares then underlying this Warrant.

     10. GOVERNING LAW. This Warrant shall be governed by and construed and enforced in accordance with, and all questions concerning the construction, validity, interpretation and performance of this Warrant shall be governed by, the internal laws of the State of New York, without giving effect to any choice of law or conflict of law provision or rule (whether of the State of New York or any other jurisdictions) that would cause the application of the laws of any jurisdictions other than the State of New York.

In the event that the Agent shall be uncertain or believe there is some ambiguity as to its duties or

rights hereunder or shall receive instructions, claims or demands from any party hereto which, in its opinion, conflict with any of the provisions of this Warrant, it shall be entitled to refrain from taking any action until it shall be given a direction in writing by the Parties which eliminates such ambiguity or uncertainty to the satisfaction of Agent or by a final and non-appealable order or judgment of a court of competent jurisdiction. The Parties agree to pursue any redress or recourse in connection with any dispute without making the Agent a party to the same.

     (c) The Agent may at any time resign and be discharged from its duties or obligations hereunder by giving thirty (30) days advance written notice of resignation to the Company and the Holder specifying a date when such resignation will take effect. Upon receiving such notice of resignation, the Holder shall promptly appoint a successor and, upon the acceptance by the successor of such appointment and the Agent shall be released from its obligations hereunder by the Company and the Holder by written instrument, a copy of which instrument shall be delivered to the resigning Agent and the successor. If the Holder has failed to appoint a successor Agent prior to the expiration of thirty (30) days following receipt of the notice of resignation, the Agent, at the Holder's expense, may petition any court of competent jurisdiction for the appointment of a successor Agent or for other appropriate relief, and any such resulting appointment shall be binding upon all of the parties hereto.

     (d) The Holder (the "Indemnifying Party") hereby agrees to indemnify, defend and save harmless the Agent and its affiliates and their respective successors, assigns, directors, officers, agents, managers, attorneys, accountants, experts, and employees (the "Indemnitees") from and against any and all liabilities, penalties, judgments, settlements, litigation, investigations, damages, losses, claims, costs or expenses (including without limitation, the fees and expenses of outside counsel) (any or all of the foregoing herein referred to as a "Losses") arising out of or in connection with (a) the Agent's execution and performance of this Escrow Agreement, tax reporting or withholding, the enforcement of any rights or remedies under or in connection with this Warrant, or as may arise by reason of any act, omission or error of the Indemnitee, except in the case of any Indemnitee to the extent that such Losses are finally adjudicated by a court of competent jurisdiction to have been primarily caused by the gross negligence or willful misconduct of such Indemnitee, or (b) its following any instructions or directions, whether joint or singular, from the Holder, except to the extent that its following any such instruction or direction is expressly forbidden by the terms hereof. The Holder acknowledge that the foregoing indemnities shall survive the resignation, replacement or removal of the Agent or the termination of this Warrant. Anything in this Warrant to the contrary notwithstanding, in no event shall the Agent be liable for special, incidental, punitive indirect or consequential loss or damage of any kind whatsoever (including but not limited to lost profits), even if the Agent has been advised of the likelihood of such loss or damage and regardless of the form of action. The provisions of this Section shall survive the termination of this Warrant and the resignation, replacement or removal of the Agent for any reason.

     (e) In consideration of the services rendered by the Agent hereunder, (a) upon the execution of this Agreement, the Agent shall receive a fee from the Holder in the amount of Ten Dollars ($1.00), which shall be paid by the Holder, and (b) Holder shall pay or reimburse the Agent upon request for all expenses, disbursements and advances, including, without limitation reasonable attorney's fees and expenses, incurred or made by it in connection with the performance of its duties Warrant.
