(iii) of the receipt by the Company of any notification with respect to the suspension of the qualification of the Registrable Securities included therein for sale in any jurisdiction or the initiation or threatening of any proceeding for such purpose, and

(iv) of the happening of any event that requires the making of any changes in the Registration Statement or the prospectus so that, as of such date, the statements therein are not misleading and do not omit to state a material fact required to be stated therein or necessary to make the statements therein (in the case of the prospectus, in the light of the circumstances under which they were made) not misleading (which notice will be accompanied by an instruction to suspend the use of the prospectus until such changes have been made);

(c) make every reasonable effort to obtain the withdrawal of any order suspending the effectiveness of any Registration Statement at the earliest possible time;

(d) furnish to each Holder, without charge, at least one copy of such Registration Statement and any post-effective amendment thereto, including financial statements, all exhibits (including those incorporated by reference) and schedules, if the Holder so requests in writing;

(e) during the Registration Period, deliver to each Holder, without charge, as many copies of the prospectus included in such Registration Statement and any amendment or supplement thereto as such Holder may reasonably request, and the Company consents to the use, consistent with the provisions hereof, of the prospectus or any amendment or supplement thereto by each of the selling Holders of Registrable Securities in connection with the offering and sale of the Registrable Securities covered by the prospectus or any amendment or supplement thereto;

6.6 Indemnification.

(a) To the fullest extent permitted by law, the Company shall indemnify each Holder, the officers, directors, agents and employees of each of them, each Person who controls any such Holder (within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act) and the officers, directors, agents and employees of each such controlling Person, with respect to (i) any registration, qualification or compliance effected pursuant to this Agreement against all claims, losses, damages and liabilities (or actions in respect thereof), including any of the foregoing incurred in settlement of any litigation, commenced or threatened (subject to Section 6.6(c) below), arising out of or based on any untrue statement (or alleged untrue statement) of a material fact contained in the Registration Statement, or any amendment or supplement thereof, any Prospectus or any form of prospectus or in any amendment or supplement thereto or in any preliminary prospectus, or based on any omission (or alleged omission) to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, in light of the circumstances in which they were made, or (ii) any violation or alleged violation by the Company of the Securities Act, the Exchange Act, or any rule or regulation promulgated under the Securities Act or the Exchange Act, and will reimburse each Holder for reasonable legal and other expenses reasonably incurred in connection with investigating or defending any such claim, loss, damage, liability or action as incurred; provided, that the Company will not be liable in any such case to the extent (but only to the extent) that any such claim, loss, damage, liability or action arises out of, relates to or is based upon: (A) any untrue statement or omission or allegation thereof is made in reliance upon and in conformity with written information furnished to the Company by or on behalf of such Holder and stated to be specifically for use in preparation of such Registration Statement or prospectus; or (B) the failure of the Holder to comply with the covenants and agreements contained in this Agreement respecting sales of Registrable Securities. Notwithstanding the foregoing, the Company will not be liable in any such case where the claim, loss, damage, liability or action arises out of or is related to the failure of the Holder to comply with the covenants and agreements contained in this Agreement respecting sales of Registrable Securities, and except that the foregoing indemnity agreement is subject to the condition that, insofar as it relates primarily to any such untrue statement or alleged untrue statement or omission or alleged omission made in the preliminary prospectus but eliminated or remedied in the amended prospectus on file with the Commission at the time the Registration Statement becomes effective or in the amended prospectus filed with the Commission pursuant to Rule 424(b) or in the prospectus subject to completion under Rule 434 promulgated under the Securities Act, which together meet the requirements of Section 10(a) of the Securities Act (the “Final Prospectus”), such indemnity agreement shall not inure to the benefit of any such Holder, any such underwriter or any such controlling Person, if a copy of the Final Prospectus furnished by the Company to the Holder for delivery was not furnished by the Holder to the Person or entity asserting the loss, liability, claim, damage or at or prior to the time such furnishing is required by the Securities Act and the Final Prospectus would have cured the defect giving rise to such loss, liability, claim, damage or action.

(b) Each Holder will, if Registrable Securities held by such Holder are included in the securities as to which such registration, qualification or compliance is being effected, indemnify the Company, each of its directors and officers, each underwriter of the Registrable Securities and each Person who controls the Company within the meaning of Section 15 of the Securities Act, against all claims, losses, damages and liabilities (or actions in respect thereof), including any of the foregoing incurred in settlement of any litigation, commenced or threatened (subject to Section 6.6(c) below), arising out of or based on any untrue statement (or alleged untrue statement) of a material fact contained in any registration statement or prospectus, or any amendment or supplement thereof, incident to any such registration, qualification or compliance, or based on any omission (or alleged omission) to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, in light of the circumstances in which they were made, and will reimburse the Company, such directors and officers, each underwriter of the Registrable Securities and each Person controlling the Company for reasonable legal and any other expenses reasonably incurred in connection with investigating or defending any such claim, loss, damage, liability or action as incurred, in each case to the extent, but only to the extent, that such untrue statement or omission or allegation thereof is made in reliance upon and in conformity with written information furnished to the Company by or on behalf of such Holder and stated to be specifically for use in preparation of such registration statement or prospectus. Notwithstanding the foregoing, in no event shall a Holder be liable for any such claims, losses, damages or liabilities in excess of the net proceeds received by such Holder from the sale of its Registrable Securities, except in the event of fraud by such Holder or intentional misrepresentation by such Holder.

(c) Each party entitled to indemnification under this Section 6.6 (the “Indemnified Party”) shall give notice to the party required to provide indemnification (the “Indemnifying Party”) promptly after such Indemnified Party has actual knowledge of any claim as to which indemnity may be sought, and shall permit the Indemnifying Party to assume the defense of any such claim or any litigation resulting therefrom, provided that counsel for the Indemnifying Party, who shall conduct the defense of such claim or litigation, shall be approved by the Indemnified Party (whose approval shall not unreasonably be withheld), and the Indemnified Party may participate in such defense at such Indemnified Party’s expense, and provided further that the failure of any Indemnified Party to give notice as provided herein shall not relieve the Indemnifying Party of its obligations under this Agreement, unless such failure is materially prejudicial to the Indemnifying Party in defending such claim or litigation. An Indemnifying Party shall not be liable for any settlement of an action or claim effected without its written consent (which consent will not be unreasonably withheld).

(d) If the indemnification provided for in this Section 6.6 is held by a court of competent jurisdiction to be unavailable to an Indemnified Party with respect to any loss, liability, claim, damage or expense referred to therein, then the Indemnifying Party, in lieu of indemnifying such Indemnified Party thereunder, shall contribute to the amount paid or payable by such Indemnified Party as a result of such loss, liability, claim, damage or expense in such proportion as is appropriate to reflect the relative fault of the Indemnifying Party on the one hand and of the Indemnified Party on the other in connection with the statements or omissions which resulted in such loss, liability, claim, damage or expense as well as any other relevant equitable considerations. The relative fault of the Indemnifying Party and of the Indemnified Party shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission to state a material fact relates to information supplied by the Indemnifying Party or by the Indemnified Party and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The Company and the Holders agree that it would not be just and equitable if contribution pursuant to this Section 6.6(d) was based solely upon the number of entities from whom contribution was requested or by any other method of allocation which does not take account of the equitable considerations referred to above in this Section 6.6(d). The amount paid or payable by an Indemnified

Party as a result of the losses, claims, damages and liabilities (or actions in respect thereof) referred to above in this Section 6.6(d) shall be deemed to include any legal or other expenses reasonably incurred by such Indemnified Party in connection with investigating or defending any such action or claim, subject to the provisions of Section 6.6(d) hereof. Notwithstanding the provisions of this Section 6.6(d), in no event shall a Holder be required to contribute any amount or make any other payments under this Agreement which in the aggregate exceed the net proceeds received by such Holder from the sale of Registrable Securities covered by such Registration Statement. No Person guilty of fraudulent misrepresentation (within the meaning of the Securities Act) shall be entitled to contribution from any Person who was not guilty of such fraudulent misrepresentation.

6.7 Suspension of Registration Rights.

(a) Each Holder agrees that, upon receipt of any notice from the Company of (i) the need for an amendment or supplement to the Registration Statement or the prospectus forming a part thereof or (ii) that the Board of Directors has determined in good faith that offers and sales pursuant to the prospectus forming part of the Registration Statement should not be made by reason of the presence of material undisclosed circumstances or developments with respect to which the disclosure that would be required in the Registration Statement would be premature or would have a Material Adverse Effect, each Holder will forthwith discontinue disposition of Registrable Securities pursuant to the Registration Statement contemplated by Section 6.2 until its receipt of copies of the supplemented or amended prospectus from the Company or confirmation of the filing of such report with the Commission by the Company, any such prospectus to be forwarded promptly to the Holder by the Company, and, if so directed by the Company, each Holder shall destroy or deliver to the Company all copies, other than permanent file copies then in such Holder’s possession, of the prospectus covering such Registrable Securities current at the time of receipt of such notice; provided, that the Company may suspend the disposition of Registrable Securities pursuant to the Registration Statement pursuant to clause (ii) above for the shortest reasonable period in the circumstances, not more than one time (not to exceed 45 days) during any six-month period, nor more than two times (not to exceed 90 days each) in any twelve-month period.

(b) As a condition to the inclusion of its Registrable Securities, each Holder shall furnish to the Company such information regarding such Holder and the distribution proposed by such Holder as the Company may reasonably request in writing or as shall be required in connection with any registration, qualification or compliance referred to in this Article 6, including the information required by the Registration Rights Questionnaire attached hereto as Exhibit B-2.

(c) Each Holder covenants and agrees that it will comply with the prospectus delivery requirements under the Securities Act as applicable to it in connection with sale of Registrable Securities pursuant to a Registration Statement.

(d) Each Holder acknowledges and agrees that the Registrable Securities sold pursuant to the Registration Statement described in this Section are not transferable on the books of the Company unless the stock certificate submitted to the transfer agent evidencing such Registrable Securities is accompanied by a certificate reasonably satisfactory to the Company to the effect that (i) the Registrable Securities have been sold in accordance with such Registration Statement and (ii) the requirement of delivering a current prospectus has been satisfied.

(e) Each Holder agrees not to take any action with respect to any distribution deemed to be made pursuant to such registration statement which would constitute a violation of Regulation M under the Exchange Act or any other applicable rule, regulation or law.

(f) At the end of the Registration Period, the Holders of Registrable Securities included in the Registration Statement shall discontinue sales of shares pursuant to such Registration Statement upon receipt of notice from the Company of its intention to remove from registration the shares covered by such Registration Statement that remain unsold, and such Holders shall notify the Company of the number of shares registered that remain unsold immediately upon receipt of such notice from the Company.

6.8 Company Information; Filings. With a view to making available to the Holders the benefits of certain rules and regulations of the Commission that at any time permit the sale of the Registrable Securities to the public without registration, the Company shall use commercially reasonable efforts to:

(a) make and keep public information available, as those terms are understood and defined in Rule 144 under the Securities Act, at all times;

(b) file with the Commission in a timely manner all reports and other documents required of the Company under the Exchange Act; and

(c) so long as a Holder owns any unregistered Registrable Securities, furnish to such Holder, upon any reasonable request, a written statement by the Company as to its compliance with Rule 144 under the Securities Act, and of the Exchange Act, a copy of the most recent annual or quarterly report of the Company, and such other reports and documents of the Company as such Holder may reasonably request in availing itself of any rule or regulation of the Commission allowing a Holder to sell any such securities without registration.

6.9 Assignment. The right to cause the Company to register Registrable Securities granted to the Holders by the Company under Section 6.1 may be assigned in full by a Holder in connection with a transfer by such Holder of its Registrable Securities, but only if: (i) such transfer may otherwise be effected in accordance with applicable securities laws; (ii) such Holder gives prior written notice of the proposed transfer to the Company including the name and address of such transferee and a copy of the transfer documents and agreements; (iii) such transferee agrees in writing with the Company to be bound by and comply with the terms and provisions of this Agreement; (iv) the transferee is an “accredited investor” as that term is defined in Rule 501 of Regulation D; and (v) such transfer is otherwise in compliance with this Agreement. Except as specifically permitted by this Section 6.9, the rights of a Holder with respect to Registrable Securities as set out herein shall not be transferable to any other Person, any such transfer or attempted transfer, and any such transfer or attempted transfer shall be null and void.

6.10 Listing. The Company shall use commercially reasonable efforts to cause all Registrable Securities covered by a Registration Statement to be listed on each securities exchange, interdealer quotation system or other market on which similar securities issued by the Company are then listed.

6.11 Rights of Third Parties. Neither the Company nor any of its security holders (other than the Holders in such capacity pursuant hereto) may include securities of the Company in the Registration Statement other than the Registrable Securities.

6.12 Piggyback Rights. If at any time during the period during which the Company is required to maintain the effectiveness of the Registration Statement, there is not an effective Registration Statement covering all of the Registrable Securities and the Company shall determine to prepare and file with the Commission a registration statement relating to an offering for its own account or the account of others under the Securities Act of any of its equity securities, other than on Form S-4 or Form S-8 (each

as promulgated under the Securities Act) or their then equivalents relating to equity securities to be issued solely in connection with any acquisition of any entity or business or equity securities issuable in connection with the stock option or other employee benefit plans, then the Company shall send to each Holder a written notice of such determination and, if within 15 days after the date of such notice, any such Holder shall so request in writing, the Company shall include in such registration statement all or any part of such Registrable Securities such Holder requests to be registered, subject to customary underwriter cutbacks applicable to all holders of registration rights.

6.13 Waiver; Amendment. With the written consent of the Company and the Holders holding at least 80% of the Registrable Securities that are then outstanding, any provision of this Article 6 may be waived (either generally or in a particular instance, either retroactively or prospectively and either for a specified period of time or indefinitely) or amended. Upon the effectuation of each such waiver or amendment, the Company shall promptly give written notice thereof to the Holders, if any, who have not previously received notice thereof or consented thereto in writing.

Warrant for the Purchase of Shares of

Common Stock


No. 2007 - [ ]		__________Shares

FOR VALUE RECEIVED, CHELSEA THERAPEUTICS INTERNATIONAL, LTD., a Delaware corporation (the “Company”), hereby certifies that [ ], its designee or its permitted assigns is entitled to purchase from the Company, at any time or from time to time commencing on March [ ], 2007 and prior to 5:00 P.M., New York City time, on March [ ], 2012 (the “Exercise Period”), [ ] fully paid and non-assessable shares of common stock, $0.0001 par value per share, of the Company for a purchase price per share of $[ ] [**120% of Purchase Price**]. Hereinafter, (i) said common stock, $0.0001 par value per share, of the Company, is referred to as the “Common Stock”; (ii) the shares of the Common Stock (subject to adjustment as set forth herein) purchasable hereunder or under any other Warrant (as hereinafter defined) are referred to as the “Warrant Shares”; (iii) the aggregate purchase price payable for the Warrant Shares purchasable hereunder is referred to as the “Aggregate Warrant Price”; (iv) the price payable (initially $[ ] per share subject to adjustment as set forth herein) for each of the Warrant Shares hereunder is referred to as the “Per Share Warrant Price”; (v) this Warrant, all similar Warrants issued on the date hereof and all warrants hereafter issued in exchange or substitution for this Warrant or such similar Warrants are referred to as the “Warrants”; (vi) the holder of this Warrant is referred to as the “Holder” and the holders of this Warrant and all other Warrants and Warrant Shares are referred to as the “Holders” and Holders of more than fifty percent (50%) of the Warrant Shares then issuable upon exercise of then outstanding Warrants are referred to as the “Majority of the Holders”; and (vii) the then Current Market Price per share of the Common Stock (the “Current Market Price”) shall be deemed to be the average closing sale price of the Common Stock for the ten (10) Trading Days (as defined below) immediately prior to such date or, in case no such reported sales take place on such days, the average of the last reported bid and asked prices of the Common Stock on such days, in either case on the principal national securities exchange on which the Common Stock is admitted to trading or listed, or if not listed or admitted to trading on any such exchange, the representative closing sale prices of the Common Stock as reported by NASDAQ, or other similar organization if NASDAQ is no longer reporting such information,

or, if the Common Stock is not reported on NASDAQ, the closing share prices for the Common Stock in the over-the-counter market as reported by the National Quotation Bureau or similar organization, or if not so available, the fair market value of the Common Stock as determined in good faith by the Company’s Board of Directors. A “Trading Day” shall mean any day on which shares of the Company’s Common Stock are sold on the respective exchange.

This Warrant is one in a series of related warrants constituting in the aggregate Warrants to purchase [ ] Warrant Shares, which were originally issued pursuant to a Subscription Agreement (the “Subscription Agreement”) between the Company and the investor named therein in connection with a private placement by the Company of its securities completed on March [__], 2007. The Aggregate Warrant Price is not subject to adjustment. Terms used but not otherwise defined herein shall have the meanings set forth in the Subscription Agreement.

1. Exercise of Warrant.

(a) This Warrant may be exercised in whole at any time, or in part from time to time, by the Holder during the Exercise Period.

(i) by the surrender of this Warrant (with the subscription form at the end hereof duly executed) at the address set forth in subsection 10(a) hereof, together with proper payment of the Aggregate Warrant Price, or the proportionate part thereof if this Warrant is exercised in part, with payment for the Warrant Shares made by certified or official bank check payable to the order of, or wire transfer of immediately available funds to, the Company.

(ii) If at the time of the exercise of this Warrant there is no effective registration statement (that the Holder may use) covering the resale of the Warrant Shares, then this Warrant may also be exchanged at such time, in whole or in part, by the surrender of this Warrant (with the cashless exercise form at the end hereof duly executed) (a “Cashless Exercise”) at the address set forth in subsection 10(a) hereof. Such presentation and surrender shall extinguish the Holder’s obligation to pay the Aggregate Warrant Price, or the proportionate part thereof if this Warrant is exercised in part. In the event of a Cashless Exercise, the Holder shall exchange its Warrant for that number of Warrant Shares subject to such Cashless Exercise multiplied by a fraction, the numerator of which shall be the difference between the then Current Market Price and the Per Share Warrant Price, and the denominator of which shall be the then Current Market Price.

(b) If this Warrant is exercised in part, this Warrant must be exercised for a number of whole shares of the Common Stock and the Holder is entitled to receive a new Warrant covering the Warrant Shares that have not been exercised and setting forth the proportionate part of the Aggregate Warrant Price applicable to such Warrant Shares. Upon surrender of this Warrant in connection with the exercise of this Warrant pursuant to the terms hereof, the Company will (i) issue a certificate or certificates in the name of the Holder for the number of whole shares of the Common Stock to which the Holder shall be entitled upon such exercise and, in lieu of any fractional share of the Common Stock to which the Holder shall be entitled, pay to the Holder cash in an amount equal to the fair value of such fractional share (determined in such reasonable manner as the Board of Directors of the Company shall determine), and (ii) deliver the other securities and properties receivable upon the exercise of this Warrant, or the proportionate part thereof, if this Warrant is exercised in part, pursuant to the provisions of this Warrant.

2. Reservation of Warrant Shares; Listing. The Company agrees that, prior to the expiration of this Warrant, the Company shall at all times (a) have authorized and in reserve, and shall keep available, solely for issuance and delivery upon the exercise of this Warrant, the shares of the Common Stock and other securities and properties as from time to time shall be receivable upon the exercise of this Warrant, free and clear of all restrictions on sale or transfer, other than under Federal or state securities laws, and free and clear of all preemptive rights and rights of first refusal and (b) use its commercially reasonable efforts to keep the Warrant Shares authorized for listing on the Nasdaq Capital Market and any other national securities exchange upon which the Company hereafter lists its Common Stock.

3. Certain Adjustments.

(a) If, at any time or from time to time after the date of this Warrant, the Company shall issue or distribute to all holders of shares of Common Stock by reason of their ownership thereof evidence of its indebtedness, any other securities of the Company or any cash, property or other assets (excluding a subdivision, combination or reclassification, or dividend or distribution payable in shares of Common Stock, referred to in subsection 3(b) (any such non-excluded event being herein called a “Special Dividend”)), the Per Share Warrant Price shall be adjusted (effective immediately prior to such issuance or distribution but after the record date for such issuance or distribution) by multiplying the Per Share Warrant Price then in effect by a fraction, the numerator of which shall be the Current Market Price in effect on the record date for such issuance or distribution less the fair market value (as determined in good faith by the Company’s Board of Directors) of the evidence of indebtedness, cash, securities or property, or other assets issued or distributed in such Special Dividend applicable to one share of Common Stock and the denominator of which shall be the Current Market Price in effect on the record date for such issuance or distribution. An adjustment made pursuant to this subsection 3(a) shall become effective immediately prior to the payment date but after the record date of any such Special Dividend. If such evidence of indebtedness, cash, securities or property, or other assets issued or distributed in such Special Dividend is not consummated in full, the Per Share Warrant Price shall be readjusted accordingly.

(b) In case the Company shall hereafter (i) pay a dividend or make a distribution on its Common Stock in shares of Common Stock, (ii) subdivide its outstanding shares of Common Stock into a greater number of shares or (iii) combine or reverse-split its outstanding shares of Common Stock into a smaller number of shares, then the Per Share Warrant Price and the number of Warrant Shares shall forthwith be proportionately decreased and increased, respectively, in the case of a subdivision, distribution or stock dividend, or proportionately increased and decreased, respectively, in the case of a combination or reverse stock split. The Aggregate Warrant Price payable for the then total number of Warrant Shares available for exercise under this Warrant shall remain the same. Adjustments made pursuant to this subsection 3(b) shall become effective on the record date in the case of a dividend or distribution, and shall become effective immediately after the effective date in the case of a subdivision or combination. If such dividend, distribution, subdivision or combination is not consummated in full, the Per Share Warrant Price and Warrant Shares shall be readjusted accordingly.

(c) In case of any capital reorganization or reclassification of capital stock of the Company, or any consolidation or merger to which the Company is a party other than a merger or consolidation in which the Company is the continuing corporation (and the Company shall not be deemed the survivor if the stockholders of the Company prior to the transaction do not own a majority of the voting securities of the Company after such transaction), or in case of any sale, transfer, conveyance or other disposition to another entity of all or substantially all of the assets of the Company, the Holder of this Warrant shall have the right thereafter to receive on the exercise of this Warrant the kind and amount of securities, cash or other property which the Holder would have owned or have been entitled to receive immediately after such reorganization, reclassification, consolidation, merger, statutory exchange, sale, conveyance or other disposition had this Warrant been exercised immediately prior to the effective date of such reorganization,

reclassification, consolidation, merger, statutory exchange, sale or conveyance and in any such case, if necessary, appropriate adjustment shall be made in the application of the provisions set forth in this Section 3 with respect to the rights and interests thereafter of the Holder of this Warrant to the end that the provisions set forth in this Section 3 shall thereafter correspondingly be made applicable, as nearly as may reasonably be, in relation to any shares of stock or other securities or property thereafter deliverable on the exercise of this Warrant. The above provisions of this subsection 3(c) shall similarly apply to successive reorganizations, reclassifications, consolidations, mergers, statutory exchanges, sales or conveyances. The Company shall require the issuer of any shares of stock or other securities or property thereafter deliverable on the exercise of this Warrant to be responsible for all of the agreements and obligations of the Company hereunder. Notice of any such reorganization, reclassification, consolidation, merger, statutory exchange, sale or conveyance and of said provisions so proposed to be made, shall be mailed to the Holders of the Warrants not less than twenty (20) days prior to such event. A sale of all or substantially all of the assets of the Company for a consideration consisting primarily of securities shall be deemed a consolidation or merger for the foregoing purposes.

(d) No adjustment in the Per Share Warrant Price shall be required unless such adjustment would require an increase or decrease of at least $0.0001; provided, however, that any adjustments which by reason of this subsection 3(d) are not required to be made shall be carried forward and taken into account in any subsequent adjustment; provided, further, however, that adjustments shall be required and made in accordance with the provisions of this Section 3 (other than this subsection 3(d)) not later than such time as may be required in order to preserve the tax-free nature of a distribution, if any, to the Holder of this Warrant or Common Stock issuable upon the exercise hereof. All calculations under this Section 3 shall be made to the $0.0001 or to the nearest 1/100th of a share, as the case may be. Anything in this Section 3 to the contrary notwithstanding, the Company shall be entitled to make such reductions in the Per Share Warrant Price, in addition to those required by this Section 3, as it in its discretion shall deem to be advisable in order that any stock dividend, subdivision of shares or distribution of rights to purchase stock or securities convertible or exchangeable for stock hereafter made by the Company to its stockholders shall not be taxable.

(e) Whenever the Per Share Warrant Price or the number of Warrant Shares is adjusted as provided in this Section 3 and upon any modification of the rights of a Holder of Warrants in accordance with this Section 3, the Company shall promptly prepare a brief statement of the facts requiring such adjustment or modification and the manner of computing the same and cause copies of such statement to be mailed to the Holders of the Warrants. The Company may, but shall not be obligated to unless requested in writing by a Majority of the Holders, obtain, at its expense, a certificate of a firm of independent public accountants of recognized standing selected by the Board of Directors (who may be the regular auditors of the Company) setting forth the Per Share Warrant Price and the number of Warrant Shares in effect after such adjustment or the effect of such modification, a brief statement of the facts requiring such adjustment or modification and the manner of computing the same and cause copies of such certificate to be mailed to the Holders of the Warrants.

(f) If the Board of Directors of the Company shall declare any dividend or other distribution with respect to the Common Stock, the Company shall mail notice thereof to the Holders of the Warrants not less than ten (10) days prior to the record date fixed for determining stockholders entitled to participate in such dividend or other distribution.

(g) If, as a result of an adjustment made pursuant to this Section 3, the Holder of any Warrant thereafter surrendered for exercise shall become entitled to receive shares of two or more classes of capital stock or shares of Common Stock and other capital stock of the Company, the Board of Directors (whose determination shall be conclusive and shall be described in a written notice to the Holder of any Warrant promptly after such adjustment) shall determine, in good faith, the allocation of the adjusted Per Share Warrant Price between or among shares of such classes of capital stock or shares of Common Stock and other capital stock.

(h) In case any event shall occur as to which the other provisions of this Section 3 are not strictly applicable but as to which the failure to make any adjustment would not fairly protect the purchase rights represented by this Warrant in accordance with the essential intent and principles of the adjustments set forth in this Section 3 then, in each such case, the Board of Directors of the Company shall in good faith determine the adjustment, if any, on a basis consistent with the essential intent and principles established herein, necessary to preserve the purchase rights represented by the Warrants. Upon such determination, the Company will promptly mail a copy thereof to the Holder of this Warrant and shall make the adjustments described therein.

4. Fully Paid Stock; Taxes. The shares of the Common Stock represented by each and every certificate for Warrant Shares delivered on the exercise of this Warrant shall, subject to compliance by the Holder with the terms hereof, at the time of such delivery, be duly authorized, validly issued and outstanding, fully paid and nonassessable, and not subject to preemptive rights or rights of first refusal imposed by any agreement to which the Company is a party, and the Company will take all such actions as may be necessary to assure that the par value, if any, per share of the Common Stock is at all times equal to or less than the then Per Share Warrant Price. The Company shall pay, when due and payable, any and all Federal and state stamp, original issue or similar taxes which may be payable in respect of the issue of any Warrant Share or any certificate thereof to the extent required because of the issuance by the Company of such security.

5. Registration Under Securities Act.

(a) The Holder shall have the right to participate in the registration rights granted to purchasers of the securities of the Company pursuant to Article 6 of the Subscription Agreement with respect to any Warrant Shares held by the Holder. By acceptance of this Warrant, the Holder agrees to comply with the provisions in Article 6 of the Subscription Agreement to same extent as if it were a party thereto.

(b) Until all of the Warrant Shares have been sold under a Registration Statement or pursuant to an exemption from registration under the Securities Act, including pursuant to Rule 144, so long as the Company’s Common Stock remains registered under the Exchange Act, the Company shall use its commercially reasonable best efforts to file with the Securities and Exchange Commission all current reports and the information as may be necessary to enable the Holder to effect sales of its shares in reliance upon Rule 144 promulgated under the Securities Act.

6. Investment Intent; Limited Transferability.

(a) By accepting this Warrant, the Holder represents to the Company that it understands that this Warrant and any securities obtainable upon exercise of this Warrant have not been registered for sale under Federal or state securities laws and are being offered and sold to the Holder pursuant to one or more exemptions from the registration requirements of such securities laws. In the absence of an effective registration of such securities or an exemption therefrom, any certificates for such securities shall bear the legend set forth on the first page hereof. The Holder understands that it must bear the economic risk of its investment in this Warrant and any securities obtainable upon exercise of this Warrant for an indefinite period of time, as this Warrant and such securities have not been registered under Federal or state securities laws and therefore cannot be sold unless subsequently registered under such laws, unless an exemption from such registration is available. The Holder further represents to the Company, by accepting this Warrant, that it has full power and authority to accept this Warrant and make the representations set forth herein.

(b) The Holder, by its acceptance of this Warrant, represents to the Company that it is acquiring this Warrant and will acquire any securities obtainable upon exercise of this Warrant for its own account for investment and not with a view to, or for sale in connection with, any distribution thereof in violation of the Securities Act. The Holder agrees, by acceptance of this Warrant, that this Warrant and any such securities issuable under this Warrant will not be sold or otherwise transferred unless (i) a registration statement with respect to such transfer is effective under the Securities Act and any applicable state securities laws or (ii) such sale or transfer is made pursuant to one or more exemptions from the registration requirements of the Securities Act.

(c) In addition to the limitations set forth in Section 1 and in accordance with the legend on the first page hereof, this Warrant may not be sold, transferred, assigned or hypothecated by the Holder except in compliance with the provisions of the Securities Act and the applicable state securities “blue sky” laws, and is so transferable only upon the books of the Company which the Company shall cause to be maintained for such purpose. The Company may treat the registered Holder of this Warrant as it appears on the Company’s books at any time as the Holder for all purposes. The Company shall permit any Holder of a Warrant or its duly authorized attorney, upon written request during ordinary business hours, to inspect and copy or make extracts from its books showing the registered Holder of this Warrant. All Warrants issued upon the transfer or assignment of this Warrant will be dated the same date as this Warrant, and all rights of the holder thereof shall be identical to those of the Holder unless, in each case, otherwise prohibited by applicable law.

(d) The Holder has been afforded (i) the opportunity to ask such questions as it has deemed necessary of, and to receive answers from, representatives of the Company concerning the terms and conditions of the Warrants or the exercise of the Warrants; and (ii) the opportunity to request such additional information which the Company possesses or can acquire without unreasonable effort or expense.

(e) The Holder did not (i) receive or review any advertisement, article, notice or other communication published in a newspaper or magazine or similar media or broadcast over television or radio, whether closed circuit, or generally available; or (ii) attend any seminar, meeting or investor or other conference to which the Holder was invited by any general solicitation or general advertising.

(f) The Holder is an “accredited investor” within the meaning of Regulation D under the Securities Act. Such Holder is acquiring the Warrants for its own account and not with a present view to, or for sale in connection with, any distribution thereof in violation of the registration requirements of the Securities Act, without prejudice, however, to such Holder’s right, subject to the provisions of the Subscription Agreement and this Warrant, at all times to sell or otherwise dispose of all or any part of such Warrants and Warrant Shares.

(g) Either by reason of such Holder’s business or financial experience or the business or financial experience of its professional advisors (who are unaffiliated with and who are not compensated by the Company or any affiliate, finder or selling agent of the Company, directly or indirectly), such Holder has the capacity to protect such Holder’s interests in connection with the transactions contemplated by this Warrant and the Subscription Agreement. The Holder, by its acceptance of this Warrant, represents to the Company that it is able to fend for itself, can bear the economic risk of its investment and has such knowledge and experience in financial or business matters that it is capable of evaluating the merits and risks of the investment in this Warrant. Holder also represents it has not been organized for the purpose of acquiring this Warrant.

7. Optional Redemption.

(a) In the event that the volume weighted average price of the Company’s Common Stock as reported on Nasdaq for any twenty (20) consecutive Trading Days is at least $12.00 per share (subject to adjustment for any stock splits, combinations, or similar events with respect to the Common Stock after the original issuance date of this Warrant) (the “Redemption Price”), the Company shall be entitled to redeem all, but not less than all, of the Warrants at a per Warrant redemption price of $0.0001, by providing sixty (60) business days’ written notice (the “Notice Period”) to the Holders. For the avoidance of doubt, this Warrant may be exercised in whole at any time, or in part from time to time, by the Holder during the Notice Period in accordance with Section 1 hereof. The Holder agrees to return the certificate representing the redeemed Warrants to the Company upon their redemption (or evidence reasonably satisfactory to the Company of the loss, theft, destruction or mutilation of this Warrant in accordance with Section 8 hereof).

(b) Notwithstanding Section 7(a) hereof, for so long as any Warrant Shares are not subject to a registration statement declared effective by the Commission or are not otherwise permitted to be immediately sold, in whole, pursuant to an exemption to registration for such resale, including pursuant to Rule 144 of the Securities Act, the Company shall not be entitled to exercise its redemption rights pursuant to Section 7(a) above.

8. Loss, etc., of Warrant. Upon receipt of evidence reasonably satisfactory to the Company of the loss, theft, destruction or mutilation of this Warrant, and of indemnity reasonably satisfactory to the Company, if lost, stolen or destroyed, and upon surrender and cancellation of this Warrant, if mutilated, the Company shall execute and deliver to the Holder a new Warrant of like date, tenor and denomination.

9. Warrant Holder Not Stockholder. This Warrant does not confer upon the Holder any right to vote on or consent to or receive notice as a stockholder of the Company, as such, in respect of any matters whatsoever, nor any other rights or liabilities as a stockholder, prior to the exercise hereof; this Warrant does, however, require certain notices to Holders as set forth herein.

10. Communication. No notice or other communication under this Warrant shall be effective or deemed to have been given unless, the same is in writing and is mailed by first-class mail, postage prepaid, or via recognized overnight courier with confirmed receipt, addressed to:

(a) the Company at Chelsea Therapeutics International, Ltd., 00000 Xxxxxxxxxx Xxxxxxxxx Xxxxx Xxxxx 000, Xxxxxxxxx, XX 00000, Attn: Chief Financial Officer, or other such address as the Company has designated in writing to the Holder; or

(b) the Holder at the address of the Holder set forth in the Subscription Agreement, or other such address as the Holder has designated in writing to the Company.

11. Headings. The headings of this Warrant have been inserted as a matter of convenience and shall not affect the construction hereof.

12. Applicable Law. This Warrant shall be governed by and construed in accordance with the law of the State of Delaware without giving effect to the principles of conflicts of law thereof.

13. No Impairment. The Company will not avoid or seek to avoid the observance or performance of any of the terms of this Warrant, but will at all times in good faith assist in the carrying out of all such

terms and in the taking of all such action as may be necessary or appropriate in order to protect the rights of the Holder against impairment.

If a question is inapplicable to you, please so state by inserting “N/A.” If you are in doubt whether a particular question requires an affirmative response from you, please furnish full particulars so that those persons responsible for preparing the Registration Statement and Prospectus can determine whether any disclosure based on your answer is required. Information requested in this questionnaire is as of the date you complete the questionnaire, unless otherwise indicated. Your furnishing such information does not necessarily mean that such information will be disclosed.

DEFINITIONS

Your answers to this questionnaire should be made upon the basis of the following definitions of terms used in this questionnaire:

The term “beneficial owner” of a security includes any Person who, directly or indirectly, through any contract, arrangement, understanding, relationship or otherwise has or shares (1) voting power, which includes the power to vote, or direct the voting of, such security or (2) investment power, which includes the power to dispose or direct the disposition of such security. A Person may be regarded as having voting power of a security which is owned (i) by his spouse or minor children or by any of his relatives or his spouse’s relatives who share the same home with him, (ii) a partnership of which he is a partner or (iii) a corporation of which he is a substantial shareholder. A Person is also deemed to be the beneficial owner of shares which that Person has the right to acquire within 60 days, including but not limited to any right to acquire through the exercise of an option, through conversion of a security, pursuant to the power to revoke a trust or pursuant to the automatic termination of a trust. Please also disclose any other rights, which you have to acquire securities of the Company on or before the ninetieth (90^th) day following the Closing Date.

The term “material,” when used to qualify a requirement for the furnishings of information as to any subject, limits the information required to those matters about which the average prudent investor should reasonably be informed before buying or selling the securities of the Company. If you are in doubt as to the materiality of certain information, you should relate sufficient facts to enable the Company and its advisors to reach a conclusion as to its materiality.

The term “Person” means any person, individual, corporation, limited liability company, partnership, trust or other governmental agency, court, authority or other body (whether foreign, federal, state, local or otherwise.

“The selling stockholders and any broker-dealers, agents or underwriters that participate with the selling stockholders in the distribution of the issued and outstanding shares of common stock or the shares of stock issuable upon exercise of warrants may be deemed to be “underwriters” within the meaning of the Securities Act, in which event any commissions received by these broker-dealers, agents or underwriters and any profits realized by the selling stockholders on the resales of the securities may be deemed to be underwriting commissions or discounts under the Securities Act. If the selling stockholders are deemed to be underwriters, the selling stockholders may be subject to certain statutory and regulatory liabilities, including liabilities imposed pursuant to Sections 11, 12 and 17 of the Securities Act and Rule 10b-5 under the Exchange Act.”

To the Purchasers

As identified on Exhibit A hereto

____________________________

Ladies and Gentlemen:

We have acted as counsel for Chelsea Therapeutics International, Ltd., a Delaware corporation (the “Company”), in connection with the issuance and sale of [ ] shares of common stock, $0.0001 par value per share, of the Company (the “Shares”), and warrants to purchase Company Common Stock (the “Warrants”), pursuant to those certain Subscription Agreements, dated as of March [ ], 2007 (the “Subscription Agreements”), between the Company and each of the subscribers listed therein (the “Subscribers”). Capitalized terms not otherwise defined in this opinion have the meaning given them in the Subscription Agreements. This opinion is furnished to you pursuant to Section 2.2(b) of the Subscription Agreements.

In rendering this opinion, we have examined originals or copies of such documents that we deemed relevant to render the opinions provided herein, including, but not limited to, the following documents:

The Subscription Agreements, including the representations of the Company contained therein (the “Representations”);

The certificate of incorporation of the Company, as in effect on the date hereof;

The Company’s bylaws, as in effect on the date hereof;

The resolutions adopted by the Board of Directors of the Company on March [ ], 2007 with respect to, among other things, the Subscription Agreements and the transactions contemplated thereby; and

The Warrants (and together with the Subscription Agreements, the “Transaction Documents”).

In connection with the opinions expressed herein we have made such examination of matters of law and of fact, as we considered appropriate or advisable for purposes hereof. As to matters of fact material to the opinions expressed herein, we have relied upon the Representations and upon certificates and statements of governmental officials and of officers of the Company. We have also examined originals or copies of such corporate documents or records of the Company as we have considered appropriate for the opinions expressed herein. We have assumed for the purposes of this opinion that the signatures on documents and instruments examined by us are authentic, that each document is what it purports to be, and that all documents submitted to us as copies conform with the originals, which facts we have not independently verified.

In rendering this opinion we have also assumed: (i) that the Subscription Agreements have been duly and validly executed and delivered by each of the Subscribers or on their behalf and constitute a valid, binding and enforceable obligation upon each of the Subscribers; (ii) that the representations and warranties made in the Subscription Agreements by each of the Subscribers are true and correct; (iii) that each of the Subscribers will make payment of the purchase price required pursuant to the Subscription Agreements and that any wire transfers tendered by any of the Subscribers will be honored; (iv) if a Subscriber is a corporation or other entity, that such Subscriber has filed any required state franchise, income or similar tax returns and have paid any required state franchise, income of similar taxes; (v) that there are no extrinsic agreements or understandings among the parties to the Subscription Agreements that would modify or interpret the terms of the Subscription Agreements or the respective rights or obligations of the parties thereunder; and (vi) each Subscriber has all requisite power and authority and have taken all necessary action to effect the transactions mentioned above, and we do not render an opinion upon the application of any federal or state law or regulation to the Subscribers’ power or authority.

As used in this opinion, the phrases “to our knowledge” or “we are not aware” means as to matters of fact that, based on the actual knowledge of individual attorneys within the firm who have worked on the Subscription Agreements and the transactions contemplated thereby and after such inquiries as we deemed appropriate, including an examination of documents referred to herein and inquiries of senior management of the Company, we find no reason to believe that the opinions expressed are factually incorrect; but beyond that, we have made no factual investigation for the purposes of rendering this opinion. Specifically, but without limitation, we have made no inquiries of securities holders of the Company.

This opinion relates solely to the laws of the State of North Carolina, the General Corporation Law of the State of Delaware and the federal securities laws of the United States and the securities laws of the State of New York, and we express no opinion with respect to the effect or application of any other laws. Special rulings of authorities administering such laws or opinions of other counsel have not been sought or obtained.

Based upon our examination of and reliance upon the foregoing and subject to the limitations, exceptions, qualifications and assumptions set forth below and except as set forth in the Subscription Agreements, we are of the opinion that as of the date hereof:

1. The Company has been duly incorporated and, based solely on a certificate dated [ ], 2007, from the Secretary of State of the State of Delaware, is validly existing as a corporation and in good standing in the State of Delaware, with the requisite corporate power and authority to own and use its properties and assets and to carry on its business as currently conducted. Based solely on a Certificate of Authorization dated [ ], 2007, from the Secretary of State of the State of North Carolina, the Company is qualified to do business as a foreign corporation in the State of North Carolina.

2. The Company has all requisite corporate power and authority to (a) execute, deliver and perform the Transaction Documents, (b) issue, sell and deliver the Shares and Warrants and, upon exercise of the Warrants in accordance with the terms thereof, the shares of Common Stock underlying the Warrants pursuant to the Transaction Documents and (c) carry out and perform its obligations under the Transaction Documents and consummate the transactions contemplated thereby.

3. The Transaction Documents have been duly executed and delivered by the Company and the consummation by the Company of the transactions contemplated thereby have been duly authorized

by all necessary action on the part of the Company. The Transaction Documents constitute legal, valid and binding obligations of the Company, enforceable against the Company according to their terms.

4. Except for such consents, approvals, authorizations, orders for filing as have been or we believe will be made or obtained in a timely manner, no approval, authorization, waiver, consent, registration, filing, qualification, license or permit of or with any court, regulatory, administrative or other governmental body is required for the execution and delivery of the Transaction Documents or the consummation of the transactions contemplated thereby.

5. The Securities have been duly authorized and, when paid for and issued in accordance with the Subscription Agreements and the Warrants, the Shares and the shares of Common Stock underlying the Warrants will be validly issued, fully paid and non-assessable. The shares of Common Stock underlying the Warrants have been duly authorized and reserved for issuance.

6. Based in part upon the representations made by each of the Subscribers in the Subscription Agreements, the offer and sale of the Securities to the Subscribers in accordance with the terms of the Subscription Agreements is exempt from the registration requirements of Section 5 of the Securities Act and from the securities registration and qualification requirements of all applicable state securities laws.

7. The authorized capital stock of the Company consists of 50,000,000 shares of capital stock, of which 45,000,000 are designated Common Stock and 5,000,000 of which are designated preferred stock.

8. The execution, delivery and performance by the Company, and the compliance by the Company with the terms of the Transaction Documents and the issuance, sale and delivery of the Shares and Warrants pursuant to the Transaction Documents and, upon exercise of the Warrants in accordance with the terms thereof, the shares of Common Stock underlying the Warrants will not (a) violate any provision of The Certificate of Incorporation or By-laws of the Company or (b) result in a breach of or constitute a default (or an event which with notice or lapse of time or both would become a default) under, or result in or permit the termination or modification of, any agreement or instrument that is included as an exhibit to the Public Filings, or (c) violate any order, writ, judgment or decree known to us to which the Company is a party or is subject.

Notwithstanding any other provision of this opinion letter, the opinions hereinabove expressed are specifically subject to the following limitations, exceptions, qualifications and assumptions:

A. No opinion is given, either express or implied, as to any document, agreement, instrument or certificate delivered or to be delivered in connection with the Subscription Agreements other than the documents specifically enumerated above and, with respect to such documents, only as expressly set forth and qualified and limited herein.

B. The enforceability of any instrument, document or agreement is subject to (i) applicable bankruptcy, reorganization, insolvency, moratorium, fraudulent conveyance and other federal and state laws affecting the rights and remedies of creditors generally, and (ii) general principles of equity limiting the availability of equitable remedies (including, but not limited to, the remedy of specific performance), whether considered in a proceeding at law or in equity.

C. Certain rights, remedies and waivers contained in the Subscription Agreements may be limited or rendered ineffective by applicable laws, public policy or judicial decisions; however, such laws and judicial decisions do not render the Subscription Agreements invalid as a whole. Provisions that

might be unenforceable due to public policy or other concerns or reasons include, but are not limited to, issues related to the waiver of procedural or substantive rights or other legal or equitable rights, including, without limitation, the consent by the Company to the jurisdiction or venue of any court or to service of process in any particular manner, disclaimers or limitations of liabilities or defenses, the waiver of notice requirements, and choice of law provisions.

D. No opinion is given with respect to any income, sales, withholding, personal property or other tax, assessment, penalty, charge or levy that may result from the transactions contemplated by the Subscription Agreements or any other agreement, from the payment of any sum, or from the performance of any obligation of the Company under the Subscription Agreements.

E. Certain provisions of the Subscription Agreements impose indemnification obligations on the parties thereto. Courts might apply public policy considerations in limiting the rights of parties seeking to obtain indemnification under circumstances where the conduct of such parties in the circumstances in question is determined to have constituted negligence.

F. We express no opinion as to the Company’s compliance or noncompliance with applicable federal or state anti-fraud statutes, laws, rules and regulations.

G. We express no opinion as to the effect of court decisions, invoking statutes or principles of equity, which have held that certain covenants and provisions of agreements are unenforceable where enforcement of such covenants or provisions under the circumstances would violate the enforcing party’s implied covenant of good faith and fair dealing.

H. The following are excluded from the scope of our opinion:

•

Federal Reserve Board margin regulations;

•

pension and employee benefits laws and regulations (ERISA);

•

federal and state antitrust and unfair competition laws and regulations;

This opinion is rendered as of the date first written above solely for your benefit in connection with the Subscription Agreements and may not be delivered to, quoted or relied upon by any person other than you, or for any other purpose, without our prior written consent, provided however, that it is expressly acknowledged that this opinion is also rendered for the benefit of LeerinkSwann & Company, Inc. and its affiliates (“Leerink”) and that Leerink may rely on his opinion. Our opinion is expressly limited to the matters set forth above and we render no opinion, whether by implication or otherwise, as to any other matters relating to the Company. We assume no obligation to advise you of facts, circumstances, events or developments which hereafter may be brought to our attention and which may alter, affect or modify the opinions expressed herein.
