      Warrant No. A-18
	
      Original Issue Date: August 22,
      2007



     EMISPHERE
TECHNOLOGIES, INC., a Delaware corporation (the “Company”), hereby certifies
that, for value received, Fort Mason Master, L.P. or its permitted registered
assigns (the “Holder”), is entitled to purchase from the Company up to a total
of 93,044 shares of common stock, $0.01 par value (the “Common Stock”), of the
Company (each such share, a “Warrant Share” and all such shares, the “Warrant
Shares”) at an exercise price equal to $3.948 per share (as adjusted from time
to time as provided herein, the “Exercise Price”), at any time and from time to
time on or after the date occurring six months after the Closing Date (the
“Trigger Date”) and through and including August 21, 2012 (the “Expiration
Date”), and subject to the following terms and conditions:

     This Warrant is one of a series of
warrants issued pursuant to those certain Subscription Agreements, each dated
August 16, 2007, by and between the Company and each the purchasers identified
therein (the “Subscription Agreements”). All such warrants are referred to
herein, collectively, as the “Warrants.” The original issuance of the Warrants
by the Company pursuant to the Subscription Agreements has been registered
pursuant to a Registration Statement on Form S-3 (File No. 333-133087) (together
with any registration statement filed by the Company pursuant to Rule 462(b)
under the Securities Act, the “Registration Statement”). 

1. Definitions. In addition to the
terms defined elsewhere in this Warrant, capitalized terms that are not
otherwise defined herein have the meanings given to such terms in the
Subscription Agreements. As used herein, the term
"Affiliate" of a person means a person that, directly or indirectly through one
or more intermediaries, controls, is controlled by, or is under common control
with, the person specified. 

2. List of Warrant Holders. The Company
shall register this Warrant, upon records to be maintained by the Company for
that purpose (the “Warrant Register”), in the name of the record Holder (which
shall include the initial Holder or, as the case may be, any registered assignee
to which this Warrant is permissibly assigned hereunder from time to time). The
Company may deem and treat the registered Holder of this Warrant as the absolute
owner hereof for the purpose of any exercise hereof or any distribution to the
Holder, and for all other purposes, absent actual notice to the
contrary.

3. List of Transfers; Restrictions on
Transfer.

     (a) This
Warrant and the Warrant Shares are subject to the restrictions on transfer set
forth in this Section 3. 

     (b) The
Company shall register any such transfer of all or any portion of this Warrant
in the Warrant Register, upon surrender of this Warrant, with the Form of
Assignment attached hereto duly completed and signed, to the Company at its
address specified herein. Upon any such registration or transfer, a new Warrant
to purchase Common Stock, in substantially the form of this Warrant (any such
new Warrant, a “New Warrant”), evidencing the portion of this Warrant so
transferred shall be issued to the transferee and a New Warrant evidencing the
remaining portion of this Warrant not so transferred, if any, shall be issued to
the transferring Holder. The acceptance of the New Warrant by the transferee
thereof shall be deemed the acceptance by such transferee of all of the rights
and obligations in respect of the New Warrant that the Holder has in respect of
this Warrant.




     (c) If,
at the time of the surrender of this Warrant in connection with any transfer of
this Warrant, the transfer of this Warrant shall not be registered pursuant to
an effective registration statement under the Securities Act and under
applicable state securities or blue sky laws, the Company may require, as a
condition of allowing such transfer (i) that the Holder or transferee of this
Warrant, as the case may be, furnish to the Company a written opinion of counsel
(which opinion shall be in form, substance and scope customary for opinions of
counsel in comparable transactions) to the effect that such transfer may be made
without registration under the Securities Act and under applicable state
securities or blue sky laws, (ii) that the holder or transferee execute and
deliver to the Company an investment letter in form and substance acceptable to
the Company and (iii) that the transferee be an “accredited investor” as defined
in Rule 501(a) promulgated under the Securities Act. 

4. Exercise and Duration of
Warrants.

     (a) All
or any part of this Warrant shall be exercisable by the registered Holder in any
manner permitted by Section 10 of this Warrant at any time and from time to time
on or after the Trigger Date and through and including the Expiration Date.
Subject to Section 11 hereof, at 5:00 p.m., New York City time, on the
Expiration Date, the portion of this Warrant not exercised prior thereto shall
be and become void and of no value and this Warrant shall be terminated and no
longer outstanding. In addition, if cashless exercise would be permitted under
Section 10(b) of this Warrant, then all or part of this Warrant may be exercised
by the registered Holder utilizing such cashless exercise provisions at any
time, or from time to time, on or after the Trigger Date and through and
including the Expiration Date. 

     (b) The
Holder may exercise this Warrant by delivering to the Company (i) an exercise
notice, in the form attached hereto (the “Exercise Notice”), completed and duly
signed, and (ii) if such Holder is not utilizing the cashless exercise
provisions set forth in this Warrant, payment of the Exercise Price for the
number of Warrant Shares as to which this Warrant is being exercised. The date
such items are delivered to the Company (as determined in accordance with the
notice provisions hereof) is an “Exercise Date.” The Holder shall not be
required to deliver the original Warrant in order to effect an exercise
hereunder. Execution and delivery of the Exercise Notice 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.


5. Delivery of Warrant
Shares.

     (a) Upon
exercise of this Warrant, the Company shall promptly (but in no event later than
three Trading Days after the Exercise Date) issue or cause to be issued and
cause to be delivered to or upon the written order of the Holder and in such
name or names as the Holder may designate (provided that, if the Registration
Statement is not then effective and the Holder directs the Company to deliver a
certificate for the Warrant Shares in a name other than that of the Holder or an
Affiliate of the Holder, it shall deliver to the Company on the Exercise Date an
opinion of counsel reasonably satisfactory to the Company to the effect that the
issuance of such Warrant Shares in such other name may be made pursuant to an
available exemption from the registration requirements of the Securities Act and
all applicable state securities or blue sky laws), a certificate for the Warrant
Shares issuable upon such exercise, free of restrictive legends unless the
Registration Statement is not then effective or the Warrant Shares are not
freely transferable without volume restrictions pursuant to Rule 144(k) under
the Securities Act. The Holder, or any Person permissibly so designated by the
Holder to receive Warrant Shares, shall be deemed to have become the holder of
record of such Warrant Shares as of the Exercise Date. If the Warrant Shares can
be issued without restrictive legends, the Company shall, upon the written
request of the Holder, use its best efforts to deliver, or cause to be
delivered, Warrant Shares hereunder electronically through the Depository Trust
and Clearing Corporation or another established clearing corporation performing
similar functions, if available; provided, that, the Company may, but will not
be required to, change its transfer agent if its current transfer agent cannot
deliver Warrant Shares electronically through the Depository Trust and Clearing
Corporation. 




     (b) If by the close of the third Trading Day after delivery of
an Exercise Notice, the Company fails to deliver to the Holder a certificate
representing the required number of Warrant Shares in the manner required
pursuant to Section 5(a), and if after such third Trading Day and prior to the
receipt of such Warrant Shares, 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 the Warrant Shares which the
Holder anticipated receiving upon such exercise (a “Buy-In”), then the Company
shall, within three Trading Days after the Holder’s request and in the Holder’s
sole discretion, either (1) pay in cash to the Holder 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 Warrant Shares, times (B) the closing bid
price on the date of the event giving rise to the Company’s obligation to
deliver such certificate.

     (c) To
the extent permitted by law, the Company’s obligations to issue and deliver
Warrant Shares in accordance with the terms hereof are absolute and
unconditional, irrespective of any action or inaction by the Holder to enforce
the same, any waiver or consent with respect to any provision hereof, the
recovery of any judgment against any Person or any action to enforce the same,
or any setoff, counterclaim, recoupment, limitation or termination, or any
breach or alleged breach by the Holder or any other Person of any obligation to
the Company or any violation or alleged violation of law by the Holder or any
other Person, and irrespective of any other circumstance that might otherwise
limit such obligation of the Company to the Holder in connection with the
issuance of Warrant Shares. Nothing herein shall limit a Holder’s right to
pursue any other remedies available to it hereunder, at law or in equity
including, without limitation, a decree of specific performance and/or
injunctive relief with respect to the Company’s failure to timely deliver
certificates representing shares of Common Stock upon exercise of the Warrant as
required pursuant to the terms hereof.

6. Charges, Taxes and Expenses.
Issuance and delivery of certificates for shares of Common Stock upon exercise
of this Warrant shall be made without charge to the Holder for any issue or
transfer tax, withholding tax, transfer agent fee or other incidental tax or
expense in respect of the issuance of such certificates, all of which taxes and
expenses shall be paid by the Company; provided, however, that the Company shall
not be required to pay any tax that may be payable in respect of any transfer
involved in the registration of any certificates for Warrant Shares or Warrants
in a name other than that of the Holder. The Holder shall be responsible for all
other tax liability that may arise as a result of holding or transferring this
Warrant or receiving Warrant Shares upon exercise hereof.

7. Replacement of Warrant. If this
Warrant is mutilated, lost, stolen or destroyed, the Company shall issue or
cause to be issued in exchange and substitution for and upon cancellation
hereof, or in lieu of and substitution for this Warrant, a New Warrant, but only
upon receipt of evidence reasonably satisfactory to the Company of such loss,
theft or destruction and customary and reasonable indemnity (which shall not
include a surety bond), if requested. Applicants for a New Warrant under such
circumstances shall also comply with such other reasonable regulations and
procedures and pay such other reasonable third-party costs as the Company may
prescribe. If a New Warrant is requested as a result of a mutilation of this
Warrant, then the Holder shall deliver such mutilated Warrant to the Company as
a condition precedent to the Company’s obligation to issue the New
Warrant.

8. Reservation of Warrant Shares. The
Company covenants that it will at all times reserve and keep available out of
the aggregate of its authorized but unissued and otherwise unreserved Common
Stock, solely for the purpose of enabling it to issue Warrant Shares upon
exercise of this Warrant as herein provided, the number of Warrant Shares that
are then issuable and deliverable upon the exercise of this entire Warrant, free
from preemptive rights or any other contingent purchase rights of persons other
than the Holder (taking into account the adjustments and restrictions of Section
9). The Company covenants that all Warrant Shares so issuable and deliverable
shall, upon issuance and the payment of the applicable Exercise Price in
accordance with the terms hereof, be duly and validly authorized, issued and
fully paid and nonassessable.




9. Certain Adjustments. The Exercise
Price and number of Warrant Shares issuable upon exercise of this Warrant are subject to adjustment from time to time as set
forth in this Section 9.

     (a) Stock Dividends and Splits. If the Company, at any time
while this Warrant is outstanding, (i) pays a stock dividend on its Common Stock
or otherwise makes a distribution on any class of capital stock that is
payable in shares of Common Stock, (ii) subdivides outstanding shares of Common
Stock into a larger number of shares, or (iii) combines outstanding shares of
Common Stock into a smaller number of shares, then in each such case the
Exercise Price shall be multiplied by a fraction of which the numerator shall be
the number of shares of Common Stock outstanding immediately before such event
and of which the denominator shall be the number of shares of Common Stock
outstanding immediately after such event. Any adjustment made pursuant to clause
(i) of this paragraph shall become effective immediately after the record date
for the determination of stockholders entitled to receive such dividend or
distribution, and any adjustment pursuant to clause (ii) or (iii) of this
paragraph shall become effective immediately after the effective date of such
subdivision or combination.

     (b) Pro
Rata Distributions. If the Company, at any time while this Warrant is
outstanding, distributes to all holders of Common Stock for no consideration (i)
evidences of its indebtedness, (ii) any security (other than a distribution of
Common Stock covered by the preceding paragraph), (iii) rights or warrants to
subscribe for or purchase any security, or (iv) any other asset (in each case,
“Distributed Property”), then, upon any exercise of this Warrant that occurs
after the record date fixed for determination of stockholders entitled to
receive such distribution, the Holder shall be entitled to receive, in addition
to the Warrant Shares otherwise issuable upon such exercise (if applicable), the
Distributed Property that such Holder would have been entitled to receive in
respect of such number of Warrant Shares had the Holder been the record holder
of such Warrant Shares immediately prior to such record date. 

     (c)
Fundamental Transactions. If, at any time while this Warrant is outstanding (i)
the Company effects any merger or consolidation of the Company with or into
another Person, in which the shareholders of the Company as of immediately prior
to the transaction own less than a majority of the outstanding stock of the
surviving entity, (ii) the Company effects any sale of all or substantially all
of its assets in one or a series of related transactions, (iii) any tender offer
or exchange offer (whether by the Company or another Person) is completed
pursuant to which holders of Common Stock are permitted to tender or exchange
their shares for other securities, cash or property, or (iv) the Company effects
any reclassification of the Common Stock or any compulsory share exchange
pursuant to which the Common Stock is effectively converted into or exchanged
for other securities, cash or property (each, a “Fundamental Transaction”), then
the Holder shall have the right thereafter to receive, upon exercise of this
Warrant, the same amount and kind of securities, cash or property as it would
have been entitled to receive upon the occurrence of such Fundamental
Transaction if it had been, immediately prior to such Fundamental Transaction,
the holder of the number of Warrant Shares then issuable upon exercise in full
of this Warrant (the “Alternate Consideration”). The Company shall not effect
any such Fundamental Transaction unless prior to or simultaneously with the
consummation thereof, any successor to the Company, surviving entity or the
corporation purchasing or otherwise acquiring such assets or other appropriate
corporation or entity shall assume the obligation to deliver to the Holder, such
Alternate Consideration 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 paragraph (c) shall similarly apply to
subsequent transactions analogous to a Fundamental Transaction.

     (d)
Number of Warrant Shares. Simultaneously with any adjustment to the Exercise
Price pursuant to paragraph (a) of this Section 9, the number of Warrant Shares
that may be purchased upon exercise of this Warrant shall be increased or
decreased proportionately, so that after such adjustment the aggregate Exercise
Price payable hereunder for the adjusted number of Warrant Shares shall be the
same as the aggregate Exercise Price in effect immediately prior to such
adjustment.

     (e)
Calculations. All calculations under this Section 9 shall be made to the nearest
cent or the nearest 1/100th of a share, as applicable. The number of shares of
Common Stock outstanding at any given time shall not include shares owned or
held by or for the account of the Company, and the disposition of any such
shares shall be considered an issue or sale of Common Stock.




     (f) Notice of Adjustments. Upon the occurrence of each
adjustment pursuant to this Section 9, the Company at its expense will, at the
written request of the Holder, promptly compute such adjustment in accordance
with the terms of this Warrant and prepare a certificate setting forth such
adjustment, including a statement of the adjusted Exercise Price and adjusted
number or type of Warrant Shares or other securities issuable upon
exercise of this Warrant (as applicable), describing the transactions giving
rise to such adjustments and showing in detail the facts upon which such
adjustment is based. Upon written request, the Company will promptly deliver a
copy of each such certificate to the Holder and to the Company’s Transfer
Agent.

     (g)
Notice of Corporate Events. If, while this Warrant is outstanding, the Company
(i) declares a dividend or any other distribution of cash, securities or other
property in respect of its Common Stock, including without limitation any
granting of rights or warrants to subscribe for or purchase any capital stock of
the Company or any Subsidiary, (ii) authorizes or approves, enters into any
agreement contemplating or solicits stockholder approval for any Fundamental
Transaction or (iii) authorizes the voluntary dissolution, liquidation or
winding up of the affairs of the Company, then, except if such notice and the
contents thereof shall be deemed to constitute material non-public information,
the Company shall deliver to the Holder a notice describing the material terms
and conditions of such transaction at least 10 Trading Days prior to the
applicable record or effective date on which a Person would need to hold Common
Stock in order to participate in or vote with respect to such transaction, and
the Company will take all reasonable steps to give Holder the practical
opportunity to exercise this Warrant prior to such time; provided, however, that
the failure to deliver such notice or any defect therein shall not affect the
validity of the corporate action required to be described in such
notice.

10. Payment of Exercise Price. The
Holder may pay the Exercise Price in one of the following manners:

     (a) Cash Exercise. The Holder may
deliver immediately available funds; or

     (b)
Cashless Exercise. If an Exercise Notice is delivered at a time when the
Registration Statement (or, in lieu thereof, a resale registration statement on
Form S-3 covering the resale of the Warrant Shares) is not then effective, then
the Holder may notify the Company in an Exercise Notice of its election to
utilize cashless exercise, in which event the Company shall issue to the Holder
the number of Warrant Shares determined as follows:

     X = Y [(A-B)/A]

               where:

     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.

     B = the Exercise Price.

     For purposes of Rule 144 promulgated
under the Securities Act, it is intended, understood and acknowledged that the
Warrant Shares issued in a cashless exercise transaction 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.

     If, but only if, at any time after
the Trigger Date there is no effective Registration Statement registering the
Warrant Shares, the Company shall use its best efforts to file a new
Registration Statement on Form S-3 pursuant to General Instruction I.B.4(a)(3)
(including compliance with General Instruction I.B.4(b) and I.B.4(c) as required
thereby) registering the Warrant Shares issuable upon exercise of the Warrant.





11. Limitations on Exercise.

     (a) Notwithstanding anything to the contrary contained herein,
the number of Warrant Shares that may be acquired by the Holder upon any
exercise of this Warrant (or otherwise in respect hereof) shall be
limited to the extent necessary to insure that, following such exercise
(or other issuance), the total number of shares of Common Stock then
beneficially owned by such Holder and its Affiliates and any other Persons whose
beneficial ownership of Common Stock would be aggregated with the Holder’s for
purposes of Section 13(d) of the Exchange Act, does not exceed 4.999% of the
total number of issued and outstanding shares of Common Stock (including for
such purpose the shares of Common Stock issuable upon such exercise). For such
purposes, beneficial ownership shall be determined in accordance with Section
13(d) of the Exchange Act and the rules and regulations promulgated thereunder.
Each delivery of an Exercise Notice hereunder will constitute a representation
by the Holder that it has evaluated the limitation set forth in this Section and
determined that issuance of the full number of Warrant Shares requested in such
Exercise Notice is permitted under this Section. The Company’s obligation to
issue shares of Common Stock in excess of the limitation referred to in this
Section shall be suspended (and, except as provided below, shall not terminate
or expire notwithstanding any contrary provisions hereof) until such time, if
any, as such shares of Common Stock may be issued in compliance with such
limitation; provided, that, if, as of 5:00 p.m., New York City time, on the
Expiration Date, the Company has not received written notice that the shares of
Common Stock may be issued in compliance with such limitation, the Company’s
obligation to issue such shares shall terminate. This provision shall not
restrict the number of shares of Common Stock that a Holder may receive or
beneficially own in order to determine the amount of securities or other
consideration that such Holder may receive in the event of a Fundamental
Transaction as contemplated in Section 9 of this Warrant. By written notice to
the Company, the Holder may waive the provisions of this Section but any such
waiver will not be effective until the 61st day after such notice is delivered
to the Company, nor will any such waiver effect any other Holder. This provision
shall not apply to Holders who, together with their Affiliates, as of the
Closing Date beneficially own (as determined in accordance with Section 13(d) of
the Exchange Act and the rules and regulations promulgated thereunder) in excess
of 5% of the total number of issued and outstanding shares of Common Stock.


     (b) Notwithstanding anything to the
contrary contained herein, the number of Warrant Shares that may be acquired by
the Holder upon any exercise of this Warrant (or otherwise in respect hereof)
shall be limited to the extent necessary to insure that, following such exercise
(or other issuance), the total number of shares of Common Stock then
beneficially owned by such Holder and its Affiliates and any other Persons whose
beneficial ownership of Common Stock would be aggregated with the Holder’s for
purposes of Section 13(d) of the Exchange Act, does not exceed 9.999% of the
total number of issued and outstanding shares of Common Stock (including for
such purpose the shares of Common Stock issuable upon such exercise). For such
purposes, beneficial ownership shall be determined in accordance with Section
13(d) of the Exchange Act and the rules and regulations promulgated thereunder.
Each delivery of an Exercise Notice hereunder will constitute a representation
by the Holder that it has evaluated the limitation set forth in this Section and
determined that issuance of the full number of Warrant Shares requested in such
Exercise Notice is permitted under this Section. The Company’s obligation to
issue shares of Common Stock in excess of the limitation referred to in this
Section shall be suspended (and, except as provided below, shall not terminate
or expire notwithstanding any contrary provisions hereof) until such time, if
any, as such shares of Common Stock may be issued in compliance with such
limitation; provided, that, if, as of 5:00 p.m., New York City time, on the
Expiration Date, the Company has not received written notice that the shares of
Common Stock may be issued in compliance with such limitation, the Company’s
obligation to issue such shares shall terminate. This provision shall not
restrict the number of shares of Common Stock that a Holder may receive or
beneficially own in order to determine the amount of securities or other
consideration that such Holder may receive in the event of a Fundamental
Transaction as contemplated in Section 9 of this Warrant. By written notice to
the Company, the Holder may waive the provisions of this Section but any such
waiver will not be effective until the 61st day after such notice is delivered
to the Company, nor will any such waiver effect any other Holder. This provision
shall not apply to Holders who, together with their Affiliates, as of the
Closing Date beneficially own (as determined in accordance with Section 13(d) of
the Exchange Act and the rules and regulations promulgated thereunder) in excess
of 10% of the total number of issued and outstanding shares of Common Stock.


12. No Fractional Shares. No fractional
Warrant Shares will be issued in connection with any exercise of this Warrant.
In lieu of any fractional shares that would otherwise be issuable, the Company
shall pay cash equal to the product of such fraction multiplied by the closing
price of one Warrant Share as reported by the applicable Trading Market on the
Exercise Date.




13. Notices. Any and all notices or
other communications or deliveries hereunder (including, without limitation, any
Exercise Notice) shall be in writing and shall be deemed given and effective on
the earliest of (i) the date of transmission, if such notice or communication is
delivered via facsimile at the facsimile number specified in this Section at or
prior to 5:00 p.m. (New York City time) on a Trading Day, (ii) the next Trading
Day after the date of transmission, if such notice or communication is delivered
via facsimile at the facsimile number specified in this Section on a day that is
not a Trading Day or later than 5:00 p.m. (New York City time) on any Trading
Day, (iii) the Trading Day following the date of mailing, if sent by nationally
recognized overnight courier service, or (iv) upon actual receipt by the party
to whom such notice is required to be given. The addresses for such notices or
communications shall be: if to the Company, to Emisphere Technologies, Inc., 765
Old Saw Mill River Road, Tarrytown, New York 10591. Attention: Chief Executive
Officer, Facsimile No.: (914) 593-8253 (or such other address as the Company
shall indicate in writing in accordance with this Section) or (ii) if to the
Holder, to the address or facsimile number appearing on the Warrant Register (or
such other address as the Company shall indicate in writing in accordance with
this Section).

14. Warrant Agent. The Company shall
serve as warrant agent under this Warrant. Upon 30 days’ notice to the Holder,
the Company may appoint a new warrant agent. Any corporation into which the
Company or any new warrant agent may be merged or any corporation resulting from
any consolidation to which the Company or any new warrant agent shall be a party
or any corporation to which the Company or any new warrant agent transfers
substantially all of its corporate trust or shareholders services business shall
be a successor warrant agent under this Warrant without any further act. Any
such successor warrant agent shall promptly cause notice of its succession as
warrant agent to be mailed (by first class mail, postage prepaid) to the Holder
at the Holder’s last address as shown on the Warrant Register.

15. Miscellaneous.

     (a) This
Warrant shall be binding on and inure to the benefit of the parties hereto and
their respective successors and assigns. Subject to the preceding sentence,
nothing in this Warrant shall be construed to give to any Person other than the
Company and the Holder any legal or equitable right, remedy or cause of action
under this Warrant. This Warrant may be amended only in writing signed by the
Company and the Holder, or their successors and assigns.

     (b) All
questions concerning the construction, validity, enforcement and interpretation
of this Warrant shall be governed by and construed and enforced in accordance
with the internal laws of the State of New York, without regard to the
principles of conflicts of law thereof. Each party agrees that all legal
proceedings concerning the interpretations, enforcement and defense of this
Warrant and the transactions herein contemplated (“Proceedings”) (whether
brought against a party hereto or its respective Affiliates, employees or
agents) shall be commenced exclusively in the New York Courts. Each party hereto
hereby irrevocably submits to the exclusive jurisdiction of the New York Courts
for the adjudication of any dispute hereunder or in connection herewith or with
any transaction contemplated hereby or discussed herein, and hereby irrevocably
waives, and agrees not to assert in any Proceeding, any claim that it is not
personally subject to the jurisdiction of any New York Court, or that such
Proceeding has been commenced in an improper or inconvenient forum. Each party
hereto hereby irrevocably waives personal service of process and consents to
process being served in any such Proceeding by mailing a copy thereof via
registered or certified mail or overnight delivery (with evidence of delivery)
to such party at the address in effect for notices to it under this Warrant and
agrees that such service shall constitute good and sufficient service of process
and notice thereof. Nothing contained herein shall be deemed to limit in any way
any right to serve process in any manner permitted by law. Each party hereto
hereby irrevocably waives, to the fullest extent permitted by applicable law,
any and all right to trial by jury in any legal proceeding arising out of or
relating to this Warrant or the transactions contemplated hereby. If either
party shall commence a Proceeding to enforce any provisions of this Warrant,
then the prevailing party in such Proceeding shall be reimbursed by the other
party for its attorney’s fees and other costs and expenses incurred with the
investigation, preparation and prosecution of such Proceeding. 

     (c) The
headings herein are for convenience only, do not constitute a part of this
Warrant and shall not be deemed to limit or affect any of the provisions
hereof.




     (d) In
case any one or more of the provisions of this Warrant shall be invalid or
unenforceable in any respect, the validity and enforceability of the remaining
terms and provisions of this Warrant shall not in any way be affected or
impaired thereby and the parties will attempt in good faith to agree upon a
valid and enforceable provision which shall be a commercially reasonable
substitute therefore, and upon so agreeing, shall incorporate such substitute
provision in this Warrant.

     (e) Prior to exercise of this
Warrant, the Holder hereof shall not, by reason of by being a Holder, be
entitled to any rights of a stockholder with respect to the Warrant
Shares
