NGAS Resources, Inc.

Convertible Note

					
	 	 	 	 	 
	Issuance Date: December 14, 2005
	 	
	Principal: U.S. $[___]

          FOR VALUE RECEIVED, NGAS Resources, Inc., a British Columbia corporation, (the “Company”),
hereby promises to pay to [KINGS ROAD INVESTMENTS LTD.] [OTHER BUYERS] or registered assigns
(“Holder”) the amount set out above as the Principal (as reduced pursuant to the terms hereof
pursuant to redemption, conversion or otherwise, the “Principal”) when due, whether upon the
Maturity Date, (each, as defined herein), acceleration, redemption or otherwise (in each case in
accordance with the terms hereof) and to pay interest (“Interest”) on any outstanding Principal at
the rate of 6.0% per annum (the “Interest Rate”), from the date set out above as the Issuance Date
(the “Issuance Date”) until the same becomes due and payable, whether upon an Interest Date (as
defined below), the Maturity Date, acceleration, conversion, redemption or otherwise (in each case,
in accordance with the terms hereof). This Convertible Note (including all Convertible Notes
issued in exchange, transfer or replacement hereof, this “Note”) is one of an issue of Convertible
Notes issued pursuant to the Securities Purchase Agreement (as defined below) on the Closing Date
(collectively, the “Notes” and such other Convertible Notes, the “Other Notes”). Certain
capitalized terms used herein are defined in Section 29.

     1. MATURITY. 

          (a) On the Maturity Date, the Holder shall surrender the Note to the Company and the Company
shall pay to the Holder, (i) an amount in Common Shares, or, at the option of the Company, in cash,
representing all outstanding Principal and (ii) an amount in cash equal to the accrued and unpaid
Interest thereon; provided that Principal shall be payable in Common Shares on the Maturity Date
if, and only if, there has been no Equity Conditions Failure during the applicable period. On or
prior to the tenth (10th) Trading Day prior to the Maturity Date (the “Maturity Election
Notice Due Date”), the Company shall deliver a written notice to the Holder (x) specifying whether
the Principal shall not be paid on the Maturity Date in Common Shares but rather in cash and (y)
certifying that there has been no Equity Conditions Failure. Principal to be paid on the Maturity
Date in Common Shares shall be paid in a number of fully paid and non-assessable (rounded to the
nearest whole share in accordance with Section 3(a)) Common Shares. If the Company shall pay the
Principal on the Maturity Date in Common Shares, then on the Maturity Date (i) (A) provided that
the Company’s transfer agent (the “Transfer Agent”) is participating in the Depository Trust
Company (“DTC”) Fast Automated Securities Transfer Program,

 

 

the Company shall, or shall cause the Transfer Agent to, credit a number of Common Shares
equal to the quotient of the outstanding Principal due on such date and the Maturity Conversion
Price (the “Maturity Conversion Shares”) to which the Holder shall be entitled to the Holder’s or
its designee’s balance account with DTC through its Deposit Withdrawal Agent Commission system, or
(B) if the foregoing shall not apply, the Company shall issue and deliver, to the address set forth
in the register maintained by the Company for such purpose pursuant to the Securities Purchase
Agreement or to such address as specified by the Holder in writing to the Company at least three
(3) Trading Days prior to the Maturity Date, a certificate, registered in the name of the Holder or
its designee, for the number of Maturity Conversion Shares to which the Holder shall be entitled
and (ii) the Company shall pay to the Holder, in cash by wire transfer of immediately available
funds, the amount of any accrued and unpaid interest on such Principal. If the Principal shall be
paid in cash, then the Company shall make such payment on the Maturity Date, together with the
amount of any accrued and unpaid interest on such Principal, by wire transfer of immediately
available funds to an account designated in writing by the Holder.

               (b) Notwithstanding anything to the contrary herein, the Company shall not be entitled to pay
any portion of the Principal on the Maturity Date in Common Shares under this Section 1 in excess
of the Holder’s Pro Rata Amount of the applicable Volume Limitation; provided, however, if the
Company is prohibited from paying any portion of the Principal in Common Shares (the “Maturity
Deficiency Shares”) due to the Volume Limitation, the Maturity Date with respect to the delivery of
those Maturity Deficiency Shares shall be automatically extended in 30-day increments until such
date when the Company shall have delivered to the Holder, following application of the applicable
Volume Limitation, all of the Maturity Deficiency Shares; provided, further, however, that in the
event that the Holder has not received all of the Maturity Deficiency Shares after three (3) such
30-day extensions, the Holder may, at its option, require the Company to deliver cash to the Holder
for the Principal amount (including any unpaid interest thereon) of this Note represented by the
undelivered Maturity Deficiency Shares.

          2. INTEREST; INTEREST RATE. Interest on this Note shall commence accruing on the Issuance
Date and shall be computed on the basis of a 360-day year comprised of twelve 30-day months and
shall be payable in arrears for each Calendar Quarter on the first day of the succeeding Calendar
Quarter during the period beginning on the Issuance Date and ending on, and including, the Maturity
Date (each, an “Interest Date”) with the first Interest Date being April 1, 2006 (each, an
“Interest Date”). Interest shall be payable on each Interest Date in cash. Prior to the payment
of Interest on an Interest Date, Interest on this Note shall accrue at the Interest Rate and be
payable in cash upon any conversion in accordance with Section 3(b)(i). Upon the occurrence and
during the continuance of an Event of Default, the Interest Rate shall be increased to twelve
percent (12.0%) per annum (the “Default Rate”). In the event that such Event of Default is
subsequently cured, the adjustment referred to in the preceding sentence shall cease to be
effective as of the date of such cure; provided that the Interest as calculated at such increased
rate during the continuance of such Event of Default shall continue to apply to the extent relating
to the days after the occurrence of such Event of Default through and including the date of cure of
such Event of Default. Interest on overdue interest shall accrue at the same rate compounded
quarterly.

          3. CONVERSION OF NOTES. This Note shall be convertible into common shares of the Company,
without par value (the “Common Shares”), on the terms and conditions set forth in this Section 3.

          (a) Conversion Right. Subject to the provisions of Section 3(d), at any time or times on or
after the Issuance Date, the Holder shall be entitled to convert any portion of the outstanding and
unpaid Conversion Amount (as defined below) into fully paid and nonassessable Common Shares in
accordance with Section 3(c), at the Conversion Rate (as defined below). The Company shall not
issue any fraction of a Common Share upon any conversion. If the issuance would result in the
issuance of a fraction of a Common Share, the Company shall round such fraction of a Common Share
up to the nearest whole share.

          (b) Conversion Rate. The number of Common Shares issuable upon conversion of any
Conversion Amount pursuant to Section 3(a) shall be determined by dividing (x) such Conversion
Amount by (y) the Conversion Price (such number of shares, the “Conversion Rate”).

                    (i) “Conversion Amount” means the portion of the Principal to be converted, redeemed or
otherwise with respect to which this determination is being made.

2

 

                    (ii) “Conversion Price” means, as of any Conversion Date (as defined below) or other date of
determination a price equal to $14.34, subject to adjustment as provided herein.

               (c) Mechanics of Conversion.

                    (i) Optional Conversion. To convert any Conversion Amount into Common Shares on any
date (a “Conversion Date”), the Holder shall (A) transmit by facsimile (or otherwise deliver), for
receipt on or prior to 11:59 p.m., New York Time, on such date, a copy of an executed notice of
conversion in the form attached hereto as Exhibit I (the “Conversion Notice”) to the
Company and (B) if required by Section 3(c)(iv), surrender this Note to a common carrier for
delivery to the Company as soon as practicable on or following such date (or an indemnification
undertaking with respect to this Note in the case of its loss, theft or destruction). On or before
the first (1st) Trading Day following the date of receipt of a Conversion Notice, the
Company shall transmit by facsimile a confirmation of receipt of such Conversion Notice to the
Holder and the Transfer Agent. On or before the third (3rd) Trading Day following the
date of receipt of a Conversion Notice (the “Share Delivery Date”), the Company shall (1) (x)
provided that the Transfer Agent is participating in the DTC Fast Automated Securities Transfer
Program, credit such aggregate number of Common Shares to which the Holder shall be entitled to the
Holder’s or its designee’s balance account with DTC through its Deposit Withdrawal Agent Commission
system or (y) if the Transfer Agent is not participating in the DTC Fast Automated Securities
Transfer Program, issue and deliver to the address as specified in the Conversion Notice, a
certificate, registered in the name of the Holder or its designee, for the number of Common Shares
to which the Holder shall be entitled, (2) pay to the Holder in cash an amount equal to the accrued
and unpaid Interest on the Conversion Amount up to and including the Conversion Date and (3) for
any conversions prior to the second (2nd) anniversary of the Issuance Date, pay any
applicable Make-Whole Amount in accordance with Section 3(c)(ii). If this Note is physically
surrendered for conversion as required by Section 3(c)(iv) and the outstanding Principal of this
Note is greater than the Principal portion of the Conversion Amount being converted, then the
Company shall as soon as practicable and in no event later than five (5) Trading Days after receipt
of this Note and at its own expense, issue and deliver to the holder a new Note (in accordance with
Section 17(d)) representing the outstanding Principal not converted. The Person or Persons
entitled to receive the Common Shares issuable upon a conversion of this Note shall be treated for
all purposes as the record holder or holders of such Common Shares on the Conversion Date.

                    (ii) Make-Whole Amount.

                    (1) If prior to the second (2nd) anniversary of the Issuance Date, the Holder
converts all or any portion of this Note pursuant to Section 3(c)(i), then upon such conversion,
the Holder shall receive the Make-Whole Amount; provided, however, that in the event that the
Closing Sale Price of the Common Shares exceeds 160% of the Conversion Price then in effect for
each of twenty (20) Trading Days out of the thirty (30) consecutive Trading Day period ended on the
Trading Day immediately prior to the Conversion Date, then the Holder shall not be entitled to
receive the Make-Whole Amount. The Company shall pay the Make-Whole Amount in Common Shares or, at
the Company’s option, in cash. Following receipt of any Conversion Notice during the period when a
Holder is entitled to receive a Make-Whole Amount hereunder, the Company shall, in its confirmation
of receipt of such Conversion Notice as required by Section 3(c)(i) (the “Conversion Notice
Confirmation”), (x) specify whether the Make-Whole Amount shall not be paid in Common Shares but
rather in cash and (y) certify that there has been no Equity Conditions Failure. Any Make-Whole
Amount to be paid upon a conversion in Common Shares shall be paid in a number of fully paid and
nonassessable Common Shares equal to the quotient of (A) the Make-Whole Amount and (B) the
Make-Whole Conversion Price. If the Make-Whole Amount shall be paid in Common Shares on the Share
Delivery Date, the Company shall (I) provided the Transfer Agent is participating in the DTC Fast
Automated Securities Transfer Program, credit such aggregate number of Common Shares to which the
Holder shall be entitled to the Holder or its designee’s balance account with DTC through its
Deposit Withdrawal Agent Commission system, or (II) if the Transfer Agent is not participating in
the DTC Fast Automated Securities Transfer Program, issue and deliver to the address as specified
in the Conversion Notice or in the register maintained by the Company for such purpose pursuant to
the Securities Purchase Agreement, a certificate, registered in the name of the Holder or its
designee, for the number of Common Shares to which the Holder shall be entitled. If the Make-Whole
Amount shall be paid in cash, then the Company shall make such payment on the Share Delivery Date
by wire transfer of immediately available funds to an account designated in writing by the Holder.
Notwithstanding the foregoing the Company shall not be entitled to pay the Make-Whole Amount in
Common Share and shall be required to pay such Make-Whole Amount in cash on the applicable Share

3

 

Delivery Date, if, unless consented to in writing by the Holder, during the period commencing
on the applicable Conversion Date through the applicable Share Delivery Date, the Equity Conditions
have not been satisfied.

                    (2) Notwithstanding anything to the contrary herein, the Company shall not be entitled to pay
any portion of the Make-Whole Amount in Common Shares under this Section 2(c)(ii) in excess of the
Holder’s Pro Rata Amount of the applicable Volume Limitation; provided, however, if the Company is
prohibited from paying any portion of the Make-Whole Amount in Common Shares (the “Make-Whole
Deficiency Shares”) due to the Volume Limitation, the Share Delivery Date with respect to delivery
of those Make-Whole Deficiency Shares shall be automatically extended in 30-day increments until
such date when the Company shall have delivered to the Holder, following application of the
applicable Volume Limitation, all of the Make-Whole Deficiency Shares; provided, further, however,
that in the event that the Holder has not received all of the Make-Whole Deficiency Shares after
three (3) such 30-day extensions, the Holder may, at its option, require the Company to deliver
cash to the Holder for the Principal amount (including any unpaid interest thereon) of this Note
represented by the undelivered Make-Whole Deficiency Shares.

                    (iii) Failure to Timely Convert. If the Company shall fail to issue a certificate to
the Holder or credit the Holder’s balance account with DTC for the number of Common Shares to which
the Holder is entitled upon conversion of any Conversion Amount on or prior to the date which is
three (3) Trading Days after the Conversion Date (a “Conversion Failure”), then (A) the Company
shall pay damages to the Holder for each day of such Conversion Failure in an amount equal to 1.5%
of the product of (I) the sum of the number of Common Shares not issued to the Holder on or prior
to the Share Delivery Date and to which the Holder is entitled, and (II) the Closing Sale Price of
the Common Shares on the Share Delivery Date and (B) the Holder, upon written notice to the
Company, may void its Conversion Notice with respect to, and retain or have returned, as the case
may be, any portion of this Note that has not been converted pursuant to such Conversion Notice;
provided that the voiding of a Conversion Notice shall not affect the Company’s obligations
to make any payments which have accrued prior to the date of such notice pursuant to this Section
3(c)(iii) or otherwise. In addition to the foregoing, if within three (3) Trading Days after the
Company’s receipt of the facsimile copy of a Conversion Notice, the Company shall fail to issue and
deliver a certificate to the Holder or credit the Holder’s balance account with DTC for the number
of Common Shares to which the Holder is entitled upon such holder’s conversion of any Conversion
Amount, and if on or after such Trading Day the Holder purchases (in an open market transaction or
otherwise) Common Shares to deliver in satisfaction of a sale by the Holder of Common Shares
issuable upon such conversion that the Holder anticipated receiving from the Company (a “Buy-In”),
then the Company shall, within three (3) Trading Days after the Holder’s request and in the
Holder’s discretion, either (i) pay cash to the Holder in an amount equal to the Holder’s total
purchase price (including brokerage commissions and other out-of-pocket expenses, if any) for the
Common Shares so purchased (the “Buy-In Price”), at which point the Company’s obligation to deliver
such certificate (and to issue such Common Shares) shall terminate, or (ii) promptly honor its
obligation to deliver to the Holder a certificate or certificates representing such Common 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 Common Shares times (B) the Closing Bid Price on the Conversion Date.

                    (iv) Book-Entry. Notwithstanding anything to the contrary set forth herein, upon
conversion of any portion of this Note in accordance with the terms hereof, the Holder shall not be
required to physically surrender this Note to the Company unless (A) the full Conversion Amount
represented by this Note is being converted or (B) the Holder has provided the Company with prior
written notice (which notice may be included in a Conversion Notice) requesting reissuance of this
Note upon physical surrender. The Holder and the Company shall maintain records showing the
Principal converted and the dates of such conversions or shall use such other method, reasonably
satisfactory to the Holder and the Company, so as not to require physical surrender of this Note
upon conversion.

                    (v) Pro Rata Conversion; Disputes. In the event that the Company receives a
Conversion Notice from more than one holder of Notes for the same Conversion Date and the Company
can convert some, but not all, of such portions of the Notes submitted for conversion, the Company,
subject to Section 3(d), shall convert from each holder of Notes electing to have Notes converted
on such date a pro rata amount of such holder’s portion of its Notes submitted for conversion based
on the principal amount of Notes submitted for conversion on such date by such holder relative to
the aggregate principal amount of all Notes submitted for conversion on such date. In the event of
a dispute as to the number of Common Shares issuable to the Holder in

4

 

connection with a conversion of this Note, the Company shall issue to the Holder the number of
Common Shares not in dispute and resolve such dispute in accordance with Section 22.

               (d) Limitations on Conversions.

                    (i) Beneficial Ownership. The Company shall not effect any conversion of this Note,
and the Holder of this Note shall not have the right to convert any portion of this Note pursuant
to Section 3(a), to the extent that after giving effect to such conversion, the Holder (together
with the Holder’s affiliates) would beneficially own in excess of 9.99% (the “Maximum Percentage”)
of the number of Common Shares outstanding immediately after giving effect to such conversion. For
purposes of the foregoing sentence, the number of Common Shares beneficially owned by the Holder
and its affiliates shall include the number of Common Shares issuable upon conversion of this Note
with respect to which the determination of such sentence is being made, but shall exclude the
number of Common Shares which would be issuable upon (A) conversion of the remaining, nonconverted
portion of this Note beneficially owned by the Holder or any of its affiliates and (B) exercise or
conversion of the unexercised or nonconverted portion of any other securities of the Company
(including, without limitation, any Other Notes or warrants) subject to a limitation on conversion
or exercise analogous to the limitation contained herein beneficially owned by the Holder or any of
its affiliates. Except as set forth in the preceding sentence, for purposes of this Section
3(d)(i), beneficial ownership shall be calculated in accordance with Section 13(d) of the
Securities Exchange Act of 1934, as amended. For purposes of this Section 3(d)(i), in determining
the number of outstanding Common Shares, the Holder may rely on the number of outstanding Common
Shares as reflected in (x) the Company’s most recent Form 10-KSB,Form 10-K, Form 10-QSB, Form 10-Q
or Form 8-K, as the case may be (y) a more recent public announcement by the Company or (z) any
other notice by the Company or the Transfer Agent setting forth the number of Common Shares
outstanding. For any reason at any time, upon the written or oral request of the Holder, the
Company shall within one (1) Trading Day confirm orally and in writing to the Holder the number of
Common Shares then outstanding. In any case, the number of outstanding Common Shares shall be
determined after giving effect to the conversion or exercise of securities of the Company,
including this Note, by the Holder or its affiliates since the date as of which such number of
outstanding Common Shares was reported. By written notice to the Company, the Holder may from time
to time increase or decrease the Maximum Percentage to any other percentage not in excess of 9.99%
specified in such notice; provided that (i) any such increase will not be effective until the
sixty-first (61st) day after such notice is delivered to the Company, and (ii) any such
increase or decrease will apply only to the Holder and not to any other holder of Notes.

                    (ii) Principal Market Regulation. The Company shall not be obligated to issue any
Common Shares upon conversion of this Note and the Holder of this Note shall not have the right to
receive upon conversion of this Note any Common Shares if the issuance of such Common Shares would
exceed the aggregate number of Common Shares which the Company may issue upon conversion or
exercise, as applicable, of the Notes and Warrants or otherwise under the Notes without breaching
the Company’s obligations under the rules or regulations of the Principal Market (the “Exchange
Cap”), except that such limitation shall not apply in the event that the Company (A) obtains the
approval of its shareholders as required by the applicable rules of the Principal Market for
issuances of Common Shares in excess of such amount or (B) obtains a written opinion from outside
counsel to the Company that such approval is not required, which opinion shall be reasonably
satisfactory to the Required Holders. Until such approval or written opinion is obtained, no
purchaser of the Notes pursuant to the Securities Purchase Agreement (the “Purchasers”) shall be
issued in the aggregate, upon conversion or exercise, as applicable, of Notes or Warrants, Common
Shares in an amount greater than the product of the Exchange Cap multiplied by a fraction, the
numerator of which is the principal amount of Notes issued to each Purchaser pursuant to the
Securities Purchase Agreement on the Closing Date and the denominator of which is the aggregate
principal amount of all Notes issued to the Purchasers pursuant to the Securities Purchase
Agreement on the Closing Date (with respect to each Purchaser, the “Exchange Cap Allocation”). In
the event that any Purchaser shall sell or otherwise transfer any of such Purchaser’s Notes, the
transferee shall be allocated a pro rata portion of such Purchaser’s Exchange Cap Allocation, and
the restrictions of the prior sentence shall apply to such transferee with respect to the portion
of the Exchange Cap Allocation allocated to such transferee. In the event that any holder of Notes
shall convert all of such holder’s Notes into a number of Common Shares which, in the aggregate, is
less than such holder’s Exchange Cap Allocation, then the difference between such holder’s Exchange
Cap Allocation and the number of Common Shares actually issued to such holder shall be allocated to
the respective Exchange Cap Allocations of the remaining holders of Notes on a pro rata basis in
proportion to the aggregate principal amount of the Notes then held by each such holder.

5

 

          4. RIGHTS UPON EVENT OF DEFAULT.

               (a) Event of Default. Each of the following events shall constitute an “Event of
Default”:

                    (i) the failure of the applicable Registration Statement required to be filed pursuant to the
Registration Rights Agreement to be declared effective by the SEC on or prior to the date that is
sixty (60) days after the applicable Effectiveness Deadline (as defined in the Registration Rights
Agreement), or, while the applicable Registration Statement is required to be maintained effective
pursuant to the terms of the Registration Rights Agreement, the effectiveness of the applicable
Registration Statement lapses for any reason (including, without limitation, the issuance of a stop
order) or is unavailable to any holder of the Notes for sale of all of such holder’s Registrable
Securities (as defined in the Registration Rights Agreement) in accordance with the terms of the
Registration Rights Agreement, and such lapse or unavailability continues for a period of ten (10)
consecutive days or for more than an aggregate of thirty (30) days in any 365-day period (other
than days during an Allowable Grace Period (as defined in the Registration Rights Agreement));

                    (ii) the suspension from trading or failure of the Common Shares to be listed on an Eligible
Market for a period of five (5) consecutive Trading Days or for more than an aggregate of ten (10)
Trading Days in any 365-day period;

                    (iii) the Company’s (A) failure to cure a Conversion Failure by delivery of the required
number of Common Shares within ten (10) Trading Days after the applicable Conversion Date or (B)
notice, written or oral, to any holder of the Notes, including by way of public announcement or
through any of its agents, at any time, of its intention not to comply with a request for
conversion of any Notes into Common Shares that is tendered in accordance with the provisions of
the Notes;

                    (iv) at any time following the tenth (10th) consecutive Trading Day that the number
of Common Shares that are available for issuance to the Holder is less than the number of Common
Shares that the Holder would be entitled to receive upon a conversion of the full Conversion Amount
of this Note (without regard to any limitations on conversion set forth in Section 3(d) or
otherwise);

                    (v) the Company’s failure to pay to the Holder any amount of Principal (including, without
limitation, the Company’s failure to pay any redemption or make-whole payments), Interest or other
amounts when and as due under this Note or any other Transaction Document (as defined in the
Securities Purchase Agreement), except, in the case of a failure to pay Interest when and as due,
in which case only if such failure continues for a period of at least three (3) Trading Days;

                    (vi) the occurrence of any default under, redemption of or acceleration prior to maturity of
Indebtedness of the Company or any of its Subsidiaries (as defined in Section 3(a) of the
Securities Purchase Agreement) that, individually or in the aggregate, has a principal amount equal
to or exceeding $100,000, other than with respect to any Other Notes;

                    (vii) the Company or any of its Subsidiaries, pursuant to or within the meaning of Title 11,
U.S. Code, or any similar U.S. or Canadian Federal, foreign, state or provincial law for the
relief of debtors (collectively, “Bankruptcy Law”), (A) commences a voluntary case, (B) consents to
the entry of an order for relief against it in an involuntary case, (C) consents to the appointment
of a receiver, trustee, assignee, liquidator or similar official (a “Custodian”), (D) makes a
general assignment for the benefit of its creditors or (E) admits in writing that it is generally
unable to pay its debts as they become due;

                    (viii) a court of competent jurisdiction enters an order or decree under any Bankruptcy Law
that (A) is for relief against the Company or any of its Subsidiaries in an involuntary case, (B)
appoints a Custodian of the Company or any of its Subsidiaries or (C) orders the liquidation of the
Company or any of its Subsidiaries;

6

 

                    (ix) a final judgment or judgments for the payment of money aggregating in excess of $100,000
are rendered against the Company or any of its Subsidiaries and which judgments are not, within
sixty (60) days after the entry thereof, bonded, discharged or stayed pending appeal, or are not
discharged within sixty (60) days after the expiration of such stay; provided, however, that any
judgment which is covered by insurance or an indemnity from a credit worthy party shall not be
included in calculating the $100,000 amount set forth above so long as the Company provides the
Holder a written statement from such insurer or indemnity provider (which written statement shall
be reasonably satisfactory to the Holder) to the effect that such judgment is clearly covered by
insurance or an indemnity and the Company will receive the proceeds of such insurance or indemnity
within thirty (30) days of the issuance of such judgment;

                    (x) the Company breaches any representation, warranty, covenant or other term or condition of
any Transaction Document, except, in the case of a breach of a covenant which is curable, only if
such breach continues for a period of at least fifteen (15) consecutive Trading Days; or

                    (xi) any Event of Default (as defined in the Other Notes) occurs with respect to any Other
Notes.

               (b) Redemption Right. Promptly after the occurrence of an Event of Default with
respect to this Note or any Other Note, the Company shall deliver written notice thereof via
facsimile and overnight courier (an “Event of Default Notice”) to the Holder. At any time after
the earlier of the Holder’s receipt of an Event of Default Notice and the Holder becoming aware of
an Event of Default, the Holder may require the Company to redeem all or any portion of this Note
by delivering written notice thereof (the “Event of Default Redemption Notice”) to the Company,
which Event of Default Redemption Notice shall indicate the portion of this Note the Holder is
electing to redeem. Each portion of this Note subject to redemption by the Company pursuant to
this Section 4(b) shall be redeemed by the Company at a price equal to the greater of (i) the
product of (x) the Conversion Amount to be redeemed and (y) the Redemption Premium and (ii) the
product of (A) the Conversion Rate with respect to such Conversion Amount in effect at such time as
the Holder delivers an Event of Default Redemption Notice and (B) the Closing Sale Price of the
Common Shares on the date immediately preceding such Event of Default (the “Event of Default
Redemption Price”). Redemptions required by this Section 4(b) shall be made in accordance with the
provisions of Section 12. To the extent redemptions required by this Section 4(b) are deemed or
determined by a court of competent jurisdiction to be prepayments of the Note by the Company, such
redemptions shall be deemed to be voluntary prepayments. The parties hereto agree that in the
event of the Company’s redemption of any portion of the Note under this Section 4(b), the Holder’s
damages would be uncertain and difficult to estimate because of the parties’ inability to predict
future interest rates and the uncertainty of the availability of a suitable substitute investment
opportunity for the Holder. Accordingly, any Redemption Premium due under this Section 4(b) is
intended by the parties to be, and shall be deemed, a reasonable estimate of the Holder’s actual
loss of its investment opportunity and not as a penalty.

          5. RIGHTS UPON FUNDAMENTAL TRANSACTION AND CHANGE OF CONTROL.

               (a) Assumption. The Company shall not enter into or be party to a Fundamental
Transaction unless (i) the Successor Entity assumes in writing all of the obligations of the
Company under this Note and the other Transaction Documents in accordance with the provisions of
this Section 5(a) pursuant to written agreements in form and substance satisfactory to the Required
Holders and approved by the Required Holders prior to such Fundamental Transaction, including
agreements to deliver to each holder of Notes in exchange for such Notes a security of the
Successor Entity evidenced by a written instrument substantially similar in form and substance to
the Notes, including, without limitation, having a principal amount and interest rate equal to the
Principal amounts and the Interest Rates of the Notes held by such holder, having similar
conversion rights as the Notes, having similar ranking to the Notes, and satisfactory to the
Required Holders and (ii) the Successor Entity is a publicly traded corporation whose common shares
are quoted on or listed for trading on an Eligible Market. Upon the occurrence of any Fundamental
Transaction, the Successor Entity shall succeed to, and be substituted for (so that from and after
the date of such Fundamental Transaction, the provisions of this Note referring to the “Company”
shall refer instead to the Successor Entity), and may exercise every right and power of the Company
and shall assume all of the obligations of the Company under this Note with the same effect as if
such Successor Entity had been named as the Company herein. Upon consummation of the Fundamental
Transaction, the Successor Entity (if other than the Company) shall deliver to the Holder
confirmation that there shall be issued upon conversion or

7

 

redemption of this Note at any time after the consummation of the Fundamental Transaction, in
lieu of the Company’s Common Shares (or other securities, cash, assets or other property)
purchasable upon the conversion or redemption of the Notes prior to such Fundamental Transaction,
such publicly traded common shares (or their equivalent) of the Successor Entity, as adjusted in
accordance with the provisions of this Note. The provisions of this Section shall apply similarly
and equally to successive Fundamental Transactions and shall be applied without regard to any
limitations on the conversion or redemption of this Note.

               (b) Redemption Right. No sooner than fifteen (15) days nor later than ten (10) days
prior to the consummation of a Change of Control, but not prior to the public announcement of such
Change of Control, the Company shall deliver written notice thereof via facsimile and overnight
courier to the Holder (a “Change of Control Notice”). At any time during the period (the “Change
of Control Period”) beginning after the Holder’s receipt of a Change of Control Notice and ending
on the date that is twenty (20) Trading Days after the consummation of such Change of Control, the
Holder may require the Company to redeem all or any portion of this Note by delivering written
notice thereof (“Change of Control Redemption Notice”) to the Company, which Change of Control
Redemption Notice shall indicate the Conversion Amount the Holder is electing to redeem. The
portion of this Note subject to redemption pursuant to this Section 5 shall be redeemed by the
Company in cash at a price equal to the greater of (x) 110% of the sum of (1) the Conversion Amount
being redeemed and (2) the amount of any accrued but unpaid Interest thereon through the date of
such redemption payment and (y) 110% of the sum of (1) the product of (A) the Conversion Amount
being redeemed multiplied by (B) the quotient determined by dividing (I) the aggregate cash
consideration and the aggregate cash value of any non-cash consideration per Common Share to be
paid to the holders of the Common Shares upon consummation of the Change of Control (any such
non-cash consideration consisting of marketable securities to be valued at the higher of the
Closing Sale Price of such securities as of the Trading Day immediately prior to or the Trading Day
following the public announcement of such proposed Change of Control) by (II) the Conversion Price
plus (2) the amount of any accrued but unpaid Interest on such Conversion Amount being redeemed
through the date of such redemption payment (the “Change of Control Redemption Price”).
Redemptions required by this Section 5 shall be made in accordance with the provisions of Section
12 and shall have priority to payments to shareholders in connection with a Change of Control. To
the extent redemptions required by this Section 5(b) are deemed or determined by a court of
competent jurisdiction to be prepayments of the Note by the Company, such redemptions shall be
deemed to be voluntary prepayments. Notwithstanding anything to the contrary in this Section 5,
until the Change of Control Redemption Price (together with any interest thereon) is paid in full,
the Conversion Amount submitted for redemption under this Section 5(c) may be converted, in whole
or in part, by the Holder into Common Shares, or in the event the Conversion Date is after the
consummation of the Change of Control, shares or equity interests of the Successor Entity
substantially equivalent to the Company’s Common Shares pursuant to Section 3. The parties hereto
agree that in the event of the Company’s redemption of any portion of the Note under this Section
5(b), the Holder’s damages would be uncertain and difficult to estimate because of the parties’
inability to predict future interest rates and the uncertainty of the availability of a suitable
substitute investment opportunity for the Holder. Accordingly, any redemption premium due under
this Section 5(b) is intended by the parties to be, and shall be deemed, a reasonable estimate of
the Holder’s actual loss of its investment opportunity and not as a penalty.

          6. RIGHTS UPON ISSUANCE OF PURCHASE RIGHTS AND OTHER CORPORATE EVENTS.

               (a) Purchase Rights. If at any time the Company grants, issues or sells any Options,
Convertible Securities or rights to purchase shares, warrants, securities or other property pro
rata to all record holders of any class of Common Shares (the “Purchase Rights”), then the Holder
will be entitled to acquire, upon the terms applicable to such Purchase Rights, the aggregate
Purchase Rights which the Holder could have acquired if the Holder had held the number of Common
Shares acquirable upon complete conversion of this Note (without taking into account any
limitations or restrictions on the convertibility of this Note) immediately before the date on
which a record is taken for the grant, issuance or sale of such Purchase Rights, or, if no such
record is taken, the date as of which the record holders of Common Shares are to be determined for
the grant, issue or sale of such Purchase Rights.

               (b) Other Corporate Events. In addition to and not in substitution for any other
rights hereunder, prior to the consummation of any Fundamental Transaction pursuant to which
holders of Common Shares are entitled to receive securities or other assets with respect to or in
exchange for Common Shares (a

8

 

“Corporate Event”), the Company shall make appropriate provision to insure that the Holder
will thereafter have the right to receive upon a conversion of this Note, at the Holder’s option,
(i) in addition to the Common Shares receivable upon such conversion, such securities or other
assets to which the Holder would have been entitled with respect to such Common Shares had such
Common Shares been held by the Holder upon the consummation of such Corporate Event (without taking
into account any limitations or restrictions on the convertibility of this Note) or (ii) in lieu of
the Common Shares otherwise receivable upon such conversion, such securities or other assets
received by the holders of Common Shares in connection with the consummation of such Corporate
Event in such amounts as the Holder would have been entitled to receive had this Note initially
been issued with conversion rights for the form of such consideration (as opposed to Common Shares)
at a conversion rate for such consideration commensurate with the Conversion Rate. Provision made
pursuant to the preceding sentence shall be in a form and substance satisfactory to the Required
Holders. The provisions of this Section shall apply similarly and equally to successive Corporate
Events and shall be applied without regard to any limitations on the conversion or redemption of
this Note.

          7. RIGHTS UPON ISSUANCE OF OTHER SECURITIES.

               (a) Adjustment of Conversion Price upon Issuance of Common Shares. If and whenever on
or after the Subscription Date, the Company issues or sells, or in accordance with this Section
7(a) is deemed to have issued or sold, any Common Shares (including the issuance or sale of Common
Shares owned or held by or for the account of the Company, but excluding Common Shares deemed to
have been issued or sold by the Company in connection with any Excluded Security) for a
consideration per share (the “New Issuance Price”) less than a price (the “Applicable Price”) equal
to the Conversion Price in effect immediately prior to such issue or sale or deemed issuance or
sale (the foregoing a “Dilutive Issuance”), then immediately after such Dilutive Issuance, the
Conversion Price then in effect shall be reduced to an amount equal to the product of (A) the
Conversion Price in effect immediately prior to such Dilutive Issuance and (B) the quotient
determined by dividing (1) the sum of (I) the product derived by multiplying the Conversion Price
in effect immediately prior to such Dilutive Issuance and the number of Common Shares Deemed
Outstanding immediately prior to such Dilutive Issuance plus (II) the consideration, if any,
received by the Company upon such Dilutive Issuance, by (2) the product derived by multiplying (I)
the Conversion Price in effect immediately prior to such Dilutive Issuance by (II) the number of
Common Shares Deemed Outstanding immediately after such Dilutive Issuance. For purposes of
determining the adjusted Conversion Price under this Section 7(a), the following shall be
applicable:

                    (i) Issuance of Options. If the Company in any manner grants or sells any Options and
the lowest price per share for which one Common Share is issuable upon the exercise of any such
Option or upon conversion or exchange or exercise of any Convertible Securities issuable upon
exercise of such Option is less than the Applicable Price, then such Common Share shall be deemed
to be outstanding and to have been issued and sold by the Company at the time of the granting or
sale of such Option for such price per share. For purposes of this Section 7(a)(i), the “lowest
price per share for which one Common Share is issuable upon the exercise of any such Option or upon
conversion or exchange or exercise of any Convertible Securities issuable upon exercise of such
Option” shall be equal to the sum of the lowest amounts of consideration (if any) received or
receivable by the Company with respect to any one Common Share upon granting or sale of the Option,
upon exercise of the Option and upon conversion or exchange or exercise of any Convertible Security
issuable upon exercise of such Option. No further adjustment of the Conversion Price shall be made
upon the actual issuance of such Common Shares or of such Convertible Securities upon the exercise
of such Options or upon the actual issuance of such Common Shares upon conversion or exchange or
exercise of such Convertible Securities.

                    (ii) Issuance of Convertible Securities. If the Company or the Company in any manner
issues or sells any Convertible Securities and the lowest price per share for which one Common
Share is issuable upon such conversion or exchange or exercise thereof is less than the Applicable
Price, then such Common Share shall be deemed to be outstanding and to have been issued and sold by
the Company at the time of the issuance or sale of such Convertible Securities for such price per
share. For the purposes of this Section 7(a)(ii), the “lowest price per share for which one Common
Share is issuable upon such conversion or exchange or exercise” shall be equal to the sum of the
lowest amounts of consideration (if any) received or receivable by the Company with respect to any
one Common Share upon the issuance or sale of the Convertible Security and upon the conversion or
exchange or exercise of such Convertible Security. No further adjustment of the Conversion Price
shall be made upon the actual issuance of such Common Shares upon conversion or exchange or
exercise of such

9

 

Convertible Securities, and if any such issue or sale of such Convertible Securities is made
upon exercise of any Options for which adjustment of the Conversion Price had been or are to be
made pursuant to other provisions of this Section 7(a), no further adjustment of the Conversion
Price shall be made by reason of such issue or sale.

                    (iii) Change in Option Price or Rate of Conversion. If the purchase price provided
for in any Options, the additional consideration, if any, payable upon the issue, conversion,
exchange or exercise of any Convertible Securities, or the rate at which any Convertible Securities
are convertible into or exchangeable or exercisable for Common Shares changes at any time, the
Conversion Price in effect at the time of such change shall be adjusted to the Conversion Price
which would have been in effect at such time had such Options or Convertible Securities provided
for such changed purchase price, additional consideration or changed conversion rate, as the case
may be, at the time initially granted, issued or sold. For purposes of this Section 7(a)(iii), if
the terms of any Option or Convertible Security that was outstanding as of the Subscription Date
are changed in the manner described in the immediately preceding sentence, then such Option or
Convertible Security and the Common Shares deemed issuable upon exercise, conversion or exchange
thereof shall be deemed to have been issued as of the date of such change. No adjustment shall be
made if such adjustment would result in an increase of the Conversion Price then in effect.

                    (iv) Calculation of Consideration Received. In case any Option is issued in
connection with the issue or sale of other securities of the Company, together comprising one
integrated transaction in which no specific consideration is allocated to such Options by the
parties thereto, the Options will be deemed to have been issued for a consideration of $.01. If
any Common Shares, Options or Convertible Securities are issued or sold or deemed to have been
issued or sold for cash, the consideration received therefor will be deemed to be the net amount
received by the Company therefor. If any Common Shares, Options or Convertible Securities are
issued or sold for a consideration other than cash, the amount of the consideration other than cash
received by the Company will be the fair value of such consideration, except where such
consideration consists of securities, in which case the amount of consideration received by the
Company will be the closing sale price of such securities on the date of receipt. If any Common
Shares, Options or Convertible Securities are issued to the owners of the non-surviving entity in
connection with any merger in which the Company is the surviving entity, the amount of
consideration therefor will be deemed to be the fair value of such portion of the net assets and
business of the non-surviving entity as is attributable to such Common Shares, Options or
Convertible Securities, as the case may be. The fair value of any consideration other than cash or
securities will be determined jointly by the Company and the Required Holders. If such parties are
unable to reach agreement within ten (10) days after the occurrence of an event requiring valuation
(the “Valuation Event”), the fair value of such consideration will be determined within five (5)
Trading Days after the tenth (10th) day following the Valuation Event by an independent, reputable
appraiser jointly selected by the Company and the Required Holders. The determination of such
appraiser shall be deemed binding upon all parties absent manifest error and the fees and expenses
of such appraiser shall be borne by the Company.

                    (v) Record Date. If the Company takes a record of the holders of Common Shares for
the purpose of entitling them (A) to receive a dividend or other distribution payable in Common
Shares, Options or in Convertible Securities or (B) to subscribe for or purchase Common Shares,
Options or Convertible Securities, then such record date will be deemed to be the date of the issue
or sale of the Common Shares deemed to have been issued or sold upon the declaration of such
dividend or the making of such other distribution or the date of the granting of such right of
subscription or purchase, as the case may be.

               (b) Adjustment of Conversion Price upon Subdivision or Combination of Common Shares.
If the Company at any time on or after the Subscription Date subdivides (by any share split, share
dividend, recapitalization or otherwise) one or more classes of its outstanding Common Shares into
a greater number of shares, the Conversion Price in effect immediately prior to such subdivision
will be proportionately reduced. If the Company at any time on or after the Subscription Date
combines (by combination, reverse share split or otherwise) one or more classes of its outstanding
Common Shares into a smaller number of shares, the Conversion Price in effect immediately prior to
such combination will be proportionately increased.

               (c) Other Events. If any event occurs of the type contemplated by the provisions of
this Section 7 but not expressly provided for by such provisions (including, without limitation,
the granting of share appreciation rights, phantom share rights or other rights with equity
features), then the Company’s Board of Directors will make an appropriate adjustment in the
Conversion Price so as to protect the rights of the Holder under

10

 

this Note; provided that no such adjustment will increase the Conversion Price as otherwise
determined pursuant to this Section 7.

          8. OPTIONAL REDEMPTION AT THE COMPANY’S ELECTION. 

               (a) General. If at any time from and after the second (2nd) anniversary of
the Issuance Date (the “Optional Redemption Eligibility Date”), (i) the Closing Sale Price of the
Common Shares exceeds 160% of the Conversion Price then in effect for each of twenty (20) Trading
Days out of any thirty (30) consecutive Trading Days following the Optional Redemption Eligibility
Date (the “Optional Redemption Condition”) and (ii) there has been no Equity Conditions Failure,
the Company shall have the right, provided the Optional Redemption Condition is also met on and as
of the Optional Redemption Date, to redeem all or any portion of the Conversion Amount then
remaining under this Note (the “Optional Redemption Amount”) as designated in the Optional
Redemption Notice, as of the Optional Redemption Date (an “Optional Redemption”). The portion of
this Note subject to redemption pursuant to this Section 8 shall be redeemed by the Company in cash
at a price equal to the Conversion Amount being redeemed plus any accrued and unpaid interest
threreon through the Optional Redemption Date (the “Optional Redemption Price”) on the Optional
Redemption Date. The Company may exercise its right to require redemption under this Section 8 by
delivering a written notice thereof by facsimile and overnight courier to all, but not less than
all, of the holders of Notes (the “Optional Redemption Notice” and the date all of the holders
received such notice is referred to as the “Optional Redemption Notice Date”) and each Optional
Redemption Notice shall be irrevocable. The Optional Redemption Notice shall state (A) the date on
which the Optional Redemption shall occur (the “Optional Redemption Date”) which date shall be not
less than ten (10) Trading Days nor more than thirty (30) Trading Days after the Optional
Redemption Notice Date, and (B) the aggregate Conversion Amount of the Notes which the Company has
elected to be subject to Optional Redemption from all of the holders of the Notes pursuant to this
Section 8 (and analogous provisions under the Other Notes) on the Optional Redemption Date;
provided, however, that the Company shall not redeem a Conversion Amount under this Section in
excess of the Holder’s Pro Rata Amount of the aggregate dollar trading volume (as reported on
Bloomberg) of the Common Shares over the ten (10) consecutive Trading Day period ending on the
Trading Day immediately preceding the Optional Redemption Notice Date. The Company may not effect
more than one Optional Redemption during any consecutive thirty (30) Trading Day period.
Notwithstanding anything to the contrary in this Section 8, until the Optional Redemption Price is
paid, in full, the Optional Redemption Amount may be converted, in whole or in part, by the Holders
into Common Shares pursuant to Section 3. All Conversion Amounts converted by the Holder after the
Optional Redemption Notice Date shall reduce the Optional Redemption Amount of this Note required
to be redeemed on the Optional Redemption Date. Redemptions made pursuant to this Section 8 shall
be made in accordance with Section 12.

               (b) Pro Rata Redemption Requirement. If the Company elects to cause an Optional
Redemption pursuant to Section 8(a), then it must simultaneously take the same action with respect
to the Other Notes. If the Company elects to cause an Optional Redemption pursuant to Section 8(a)
(or similar provisions under the Other Notes) with respect to less than all of the Conversion
Amounts of the Notes then outstanding, then the Company shall require redemption of a Conversion
Amount from each of the holders of the Notes equal to the product of (i) the aggregate Conversion
Amount of Notes which the Company has elected to cause to be redeemed pursuant to Section 8(a),
multiplied by (ii) the fraction, the numerator of which is the sum of the aggregate initial
principal amount of the Notes purchased by such holder of outstanding Notes and the denominator of
which is the sum of the aggregate initial principal amount of the Notes purchased by all holders
holding outstanding Notes (such fraction with respect to each holder is referred to as its
“Redemption Allocation Percentage”, and such amount with respect to each holder is referred to as
its “Pro Rata Redemption Amount”); provided, however that in the event that any holder’s Pro Rata
Redemption Amount exceeds the outstanding Principal amount of such holder’s Note, then such excess
Pro Rata Redemption Amount shall be allocated amongst the remaining holders of Notes in accordance
with the foregoing formula. In the event that the initial holder of any Notes shall sell or
otherwise transfer any of such holder’s Notes, the transferee shall be allocated a pro rata portion
of such holder’s Redemption Allocation Percentage and Pro Rata Redemption Amount.

          9. TAXES.

               (a) Any and all payments made by the Company hereunder, including any amounts received on a
conversion or redemption of the Note and any amounts on account of interest or deemed interest,
must

11

 

be made by it without any Tax Deduction, unless a Tax Deduction is required by law. If the
Company is aware that it must make a Tax Deduction (or that there is a change in the rate or the
basis of a Tax Deduction), it must notify the Holder promptly.

               (b) If a Tax Deduction is required by law to be made by the Company, subject to Section 9(a)
above, the amount of the payment due from the Company will be increased to an amount which (after
making the Tax Deduction) leaves an amount equal to the payment which would have been due if no Tax
Deduction had been required. If the Company is required to make a Tax Deduction, it must make the
minimum Tax Deduction allowed by law and must make any payment required in connection with that Tax
Deduction within the time allowed by law.

               (c) As soon as practicable after making a Tax Deduction or a payment required in connection
with a Tax Deduction, the Company must deliver to the Holder any official receipt or form, if any,
provided by or required by the taxing authority to whom the Tax Deduction was paid.

               (d) In addition, the Company agrees to pay in accordance with applicable law any present or
future stamp or documentary taxes or any other excise or property taxes, charges or similar levies
that arise from any payment made hereunder or in connection with the execution, delivery,
registration or performance of, or otherwise with respect to, this Note (“Other Taxes”). As soon
as practicable after making a payment of Other Taxes, the Company must deliver to the Holder any
official receipt or form, if any, provided by or required by the taxing authority to whom the Tax
Deduction was paid.

               (e) The obligations of the Company under this Section 9 shall survive the termination of this
Note and the payment of the Note and all other amounts payable hereunder.

          10. NONCIRCUMVENTION. The Company hereby covenants and agrees that the Company will not,
by amendment of its Notice of Articles, Articles or through any reorganization, transfer of assets,
consolidation, merger, scheme of arrangement, dissolution, issue or sale of securities, or any
other voluntary action, avoid or seek to avoid the observance or performance of any of the terms of
this Note, and will at all times in good faith carry out all of the provisions of this Note and
take all action as may be required to protect the rights of the Holder of this Note. 

          11. RESERVATION OF AUTHORIZED SHARES.

               (a) Reservation. The Company shall have sufficient authorized and unissued Common
Shares for each of the Notes equal to 150% of the number of Common Shares necessary to effect the
conversion at the Conversion Rate with respect to the Conversion Amount of each such Note as of the
Issuance Date. So long as any of the Notes are outstanding, the Company shall take all action
necessary to reserve and keep available out of its authorized and unissued Common Shares, solely
for the purpose of effecting the conversion of the Notes, 150% of the number of Common Shares as
shall from time to time be necessary to effect the conversion of all of the Notes then outstanding;
provided that at no time shall the number of Common Shares so available be less than the number of
shares required to be reserved by the previous sentence (without regard to any limitations on
conversions) (the “Required Amount”).

               (b) Insufficient Authorized Shares. If at any time while any of the Notes remain
outstanding the Company does not have a sufficient number of authorized and unissued Common Shares
to satisfy its obligation to have available for issuance upon conversion of the Notes at least a
number of Common Shares equal to the Required Amount (an “Authorized Share Failure”), then the
Company shall as promptly as practicable take all action necessary to increase the Company’s
authorized Common Shares to an amount sufficient to allow the Company to have available the
Required Amount for the Notes then outstanding.

          12. HOLDER’S REDEMPTIONS.

               (a) Mechanics. The Company shall deliver the applicable Event of Default Redemption
Price to the Holder within five (5) Trading Days after the Company’s receipt of the Holder’s Event
of Default

12

 

Redemption Notice. If the Holder has submitted a Change of Control Redemption Notice in
accordance with Section 5(b), the Company shall deliver the applicable Change of Control Redemption
Price to the Holder concurrently with the consummation of such Change of Control if such notice is
received prior to the consummation of such Change of Control and within five (5) Trading Days after
the Company’s receipt of such notice otherwise (the “Change of Control Redemption Date”). The
Company shall deliver the Optional Redemption Price to the Holder on the Optional Redemption Date.
In the event of a redemption of less than all of the Conversion Amount of this Note, the Company
shall promptly cause to be issued and delivered to the Holder a new Note (in accordance with
Section 17(d)) representing the outstanding Principal which has not been redeemed. In the event
that the Company does not pay the applicable Redemption Price to the Holder within the time period
required, at any time thereafter and until the Company pays such unpaid Redemption Price in full,
the Holder shall have the option, in lieu of redemption, to require the Company to promptly return
to the Holder all or any portion of this Note representing the Conversion Amount that was submitted
for redemption and for which the applicable Redemption Price has not been paid. Upon the Company’s
receipt of such notice, (x) the Redemption Notice shall be null and void with respect to such
Conversion Amount, (y) the Company shall immediately return this Note, or issue a new Note (in
accordance with Section 17(d)) to the Holder representing such Conversion Amount and (z) the
Conversion Price of this Note or such new Notes shall be adjusted to the lesser of (A) the
Conversion Price as in effect on the date on which the Redemption Notice is voided and (B) the
lowest Closing Bid Price of the Common Shares during the period beginning on and including the date
on which the Redemption Notice is delivered to the Company and ending on and including the date on
which the Redemption Notice is voided.

               (b) Redemption by Other Holders. Upon the Company’s receipt of notice from any of the
holders of the Other Notes for redemption or repayment as a result of an event or occurrence
substantially similar to the events or occurrences described in Section 4(b) or Section 5(b) (each,
an “Other Redemption Notice”), the Company shall immediately, but no later than one (1) Trading Day
of its receipt thereof, forward to the Holder by facsimile a copy of such notice. If the Company
receives a Redemption Notice and one or more Other Redemption Notices, during the seven (7) Trading
Day period beginning on and including the date which is three (3) Trading Days prior to the
Company’s receipt of the Holder’s Redemption Notice and ending on and including the date which is
three (3) Trading Days after the Company’s receipt of the Holder’s Redemption Notice and the
Company is unable to redeem all principal, interest and other amounts designated in such Redemption
Notice and such Other Redemption Notices received during such seven (7) Trading Day period, then
the Company shall redeem a pro rata amount from each holder of the Notes (including the Holder)
based on the principal amount of the Notes submitted for redemption pursuant to such Redemption
Notice and such Other Redemption Notices received by the Company during such seven (7) Trading Day
period.

          13. VOTING RIGHTS. The Holder shall have no voting rights as the holder of this Note,
except as provided by law, the Business Corporations Act (British Columbia) and as expressly
provided in this Note.

          14. RIGHTS UPON DISTRIBUTION OF ASSETS. Subject to the provisions of Section 4(j) of
the Securities Purchase Agreement, if the Company shall declare or make any dividend or other
distribution of its assets (or rights to acquire its assets) to holders of Common Shares, by way of
return of capital or otherwise (including, without limitation, any distribution of cash, shares or
other securities, property or options by way of a dividend, spin off, reclassification, corporate
rearrangement, scheme of arrangement or other similar transaction) (a “Distribution”), at any time
after the issuance of this Note, then, in each such case any Conversion Price in effect immediately
prior to the close of business on the record date fixed for the determination of holders of Common
Shares entitled to receive the Distribution shall be reduced, effective as of the close of business
on such record date, to a price determined by multiplying such Conversion Price by a fraction of
which (i) the numerator shall be the Closing Bid Price of the Common Shares on the trading day
immediately preceding such record date minus the value of the Distribution (as determined in good
faith by the Company’s Board of Directors) applicable to one Common Share, and (ii) the denominator
shall be the Closing Bid Price of the Common Shares on the trading day immediately preceding such
record date.

          15. VOTE TO ISSUE, OR CHANGE THE TERMS OF, NOTES. The affirmative vote, at a meeting
duly called for such purpose or the written consent without a meeting, of the Required Holders
shall be required for any change or amendment to this Note or the Other Notes. Any change or
amendment so approved shall be binding upon all existing and future holders of this Note and any
Other Notes.

13

 

          16. TRANSFER. This Note and any Common Shares issued upon conversion of this Note may be
offered, sold, assigned or transferred by the Holder without the consent of the Company, subject
only to the provisions of Section 2(f) of the Securities Purchase Agreement.

          17. REISSUANCE OF THIS NOTE.

               (a) Transfer. If this Note is to be transferred, the Holder shall surrender this Note
to the Company, whereupon the Company will forthwith issue and deliver upon the order of the Holder
a new Note (in accordance with Section 17(d)), registered as the Holder may request, representing
the outstanding Principal being transferred by the Holder and, if less then the entire outstanding
Principal is being transferred, a new Note (in accordance with Section 17(d)) to the Holder
representing the outstanding Principal not being transferred. The Holder and any assignee, by
acceptance of this Note, acknowledge and agree that, by reason of the provisions of Section
3(c)(iv) following conversion or redemption of any portion of this Note, the outstanding Principal
represented by this Note may be less than the Principal stated on the face of this Note.

               (b) Lost, Stolen or Mutilated Note. Upon receipt by the Company of evidence
reasonably satisfactory to the Company of the loss, theft, destruction or mutilation of this Note,
and, in the case of loss, theft or destruction, of any indemnification undertaking by the Holder to
the Company in customary form and, in the case of mutilation, upon surrender and cancellation of
this Note, the Company shall execute and deliver to the Holder a new Note (in accordance with
Section 17(d)) representing the outstanding Principal.

Warrant To Purchase Common Stock

Warrant No.:                    

Number of Shares of Common Stock:___

Date of Issuance: December 14, 2005 (“Issuance Date”)

          NGAS RESOURCES, INC., a corporation incorporated under the laws of the Province of British of
Columbia (the “Company”), hereby certifies that, for good and valuable consideration, the receipt
and sufficiency of which are hereby acknowledged, [KINGS ROAD INVESTMENTS LTD.] [OTHER BUYERS], the
registered holder hereof or its permitted assigns (the “Holder”), is entitled, subject to the terms
set forth below, to purchase from the Company, at the Exercise Price (as defined below) then in
effect, upon surrender or exercise of this Warrant to Purchase Common Stock (including any Warrants
to Purchase Common Stock issued in exchange, transfer or replacement hereof, the “Warrant”), at any
time or times on or after the date hereof, but not after 11:59 p.m., New York Time, on the
Expiration Date (as defined below), ___fully paid nonassessable shares of Common Stock
(as defined below) (the “Warrant Shares”). Except as otherwise defined herein, capitalized terms
in this Warrant shall have the meanings set forth in Section 15. This Warrant is one of the
Warrants to purchase Common Stock (the “SPA Warrants”) issued pursuant to Section 1 of that certain
Securities Purchase Agreement, dated as of December 13, 2005 (the “Subscription Date”), by and
among the Company and the investors (the “Buyers”) referred to therein (the “Securities Purchase
Agreement”).

     1. EXERCISE OF WARRANT.

               (i) Mechanics of Exercise. Subject to the terms and conditions hereof (including,
without limitation, the limitations set forth in Section 1(f)), this Warrant may be exercised by
the Holder on any day on or after the date hereof, in whole or in part, by (i) delivery of a
written notice, in the form attached hereto as Exhibit A (the “Exercise Notice”), of the
Holder’s election to exercise this Warrant and (ii) (A) payment to the Company of an amount equal
to the applicable Exercise Price multiplied by the number of Warrant Shares as to which this
Warrant is being exercised (the “Aggregate Exercise Price”) in cash or wire transfer of immediately
available funds or (B) by notifying the Company that this Warrant is being exercised pursuant to a
Cashless Exercise (as defined in Section 1(d)). 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 with respect to less than all of the Warrant Shares shall have the same effect as
cancellation of the original Warrant and issuance of a new Warrant evidencing the right to purchase
the remaining number of Warrant Shares. On or before the first Business Day following the date on
which the Company has received each of the Exercise Notice and the Aggregate Exercise Price (or
notice of a Cashless Exercise) (the “Exercise Delivery Documents”), the Company shall transmit by
facsimile an acknowledgment of confirmation of receipt of the Exercise Delivery Documents to the
Holder and the Company’s transfer agent (the “Transfer Agent”). On or before the third Business
Day following the date on which the Company has received all of the Exercise Delivery Documents
(the “Share Delivery Date”), the Company shall (X)

 

 

provided that the Transfer Agent is participating in The Depository Trust Company (“DTC”) Fast
Automated Securities Transfer Program, upon the request of the Holder, credit such aggregate number
of shares of Common Stock to which the Holder is entitled pursuant to such exercise to the Holder’s
or its designee’s balance account with DTC through its Deposit Withdrawal Agent Commission system,
or (Y) if the Transfer Agent is not participating in the DTC Fast Automated Securities Transfer
Program, issue and dispatch by overnight courier to the address as specified in the Exercise
Notice, a certificate, registered in the Company’s share register in the name of the Holder or its
designee, for the number of shares of Common Stock to which the Holder is entitled pursuant to such
exercise. Upon delivery of the Exercise Notice and Aggregate Exercise Price referred to in clause
(ii)(A) above or notification to the Company of a Cashless Exercise referred to in Section 1(d),
the Holder shall be deemed for all corporate purposes to have become the holder of record of the
Warrant Shares with respect to which this Warrant has been exercised, irrespective of the date of
delivery of the certificates evidencing such Warrant Shares. If this Warrant is submitted in
connection with any exercise pursuant to this Section 1(a) and the number of Warrant Shares
represented by this Warrant submitted for exercise is greater than the number of Warrant Shares
being acquired upon an exercise, then the Company shall as soon as practicable and in no event
later than three Business Days after any exercise and at its own expense, issue a new Warrant (in
accordance with Section 7(d)) representing the right to purchase the number of Warrant Shares
purchasable immediately prior to such exercise under this Warrant, less the number of Warrant
Shares with respect to which this Warrant is exercised. No fractional shares of Common Stock are
to be issued upon the exercise of this Warrant, but rather the number of shares of Common Stock to
be issued shall be rounded up to the nearest whole number. The Company shall pay any and all taxes
which may be payable with respect to the issuance and delivery of Warrant Shares upon exercise of
this Warrant.

          (ii) Exercise Price. For purposes of this Warrant, “Exercise Price” means $13.04,
subject to adjustment as provided herein.

          (iii) Company’s Failure to Timely Deliver Securities. If the Company shall fail for
any reason or for no reason to issue to the Holder within three (3) Business Days of receipt of the
Exercise Delivery Documents, a certificate for the number of shares of Common Stock to which the
Holder is entitled and register such shares of Common Stock on the Company’s share register or to
credit the Holder’s balance account with DTC for such number of shares of Common Stock to which the
Holder is entitled upon the Holder’s exercise of this Warrant, then, in addition to all other
remedies available to the Holder, the Company shall pay in cash to the Holder on each day after
such third Business Day that the issuance of such shares of Common Stock is not timely effected an
amount equal to 1.5% of the product of (A) the sum of the number of shares of Common Stock not
issued to the Holder on a timely basis and to which the Holder is entitled and (B) the Closing Sale
Price of the shares of Common Stock on the trading day immediately preceding the last possible date
which the Company could have issued such shares of Common Stock to the Holder without violating
Section 1(a). In addition to the foregoing, if within three (3) Business Days after the Company’s
receipt of the facsimile copy of a Exercise Notice the Company shall fail to issue and deliver a
certificate to the Holder and register such shares of Common Stock on the Company’s share register
or credit the Holder’s balance account with DTC for the number of shares of Common Stock to which
the Holder is entitled upon such holder’s exercise hereunder, and if on or after such Business Day
the Holder purchases (in an open market transaction or otherwise) shares of Common Stock to deliver
in satisfaction of a sale by the Holder of shares of Common Stock issuable upon such exercise that
the Holder anticipated receiving from the Company (a
“Buy-In”), then the Company shall, within
three (3) Business Days after the Holder’s request and in the Holder’s discretion, either (i) pay
cash to the Holder in an amount equal to the Holder’s total purchase price (including brokerage
commissions, if any) for the shares of Common Stock so purchased (the “Buy-In Price"), at which
point the Company’s obligation to deliver such certificate (and to issue such shares of Common
Stock) shall terminate, or (ii) promptly honor its obligation to deliver to the Holder a
certificate or certificates representing such shares of Common Stock and pay cash to the Holder in
an amount equal to the excess (if any) of the Buy-In Price over the product of (A) such number of
shares of Common Stock, times (B) the Closing Bid Price on the date of exercise.

          (iv) Cashless Exercise. Notwithstanding anything contained herein to the contrary, if
a Registration Statement (as defined in the Registration Rights Agreement) covering the Warrant
Shares that are the subject of the Exercise Notice (the “Unavailable Warrant Shares”) is not
available for the resale of such Unavailable Warrant Shares, the Holder may, in its sole
discretion, exercise this Warrant in whole or in part and, in lieu of making the cash payment
otherwise contemplated to be made to the Company upon such exercise in payment of the Aggregate
Exercise Price, elect instead to receive upon such exercise the “Net Number” of shares of Common
Stock determined according to the following formula (a “Cashless Exercise”):

2

 

	 	 	 	 	 	 	 
	 

	 	Net Number =
	 	(A x B) - (A x C)
	 	 
	 

	 	 	 	B	 	 

          For purposes of the foregoing formula:

A= the total number of shares with respect to which this Warrant is then being
exercised.

B= the Closing Sale Price of the shares of Common Stock (as reported by Bloomberg)
on the date immediately preceding the date of the Exercise Notice.

C= the Exercise Price then in effect for
the applicable Warrant Shares at the time of such
exercise.

               (v) Disputes. In the case of a dispute as to the determination of the Exercise Price
or the arithmetic calculation of the Warrant Shares, the Company shall promptly issue to the Holder
the number of Warrant Shares that are not disputed and resolve such dispute in accordance with
Section 12.

               (vi) Limitations on Exercises.

(i) Beneficial Ownership. The Company shall not effect the exercise
of this Warrant, and the Holder shall not have the right to exercise this
Warrant, to the extent that after giving effect to such exercise, such
Person (together with such Person’s affiliates) would beneficially own in
excess of 9.99% of the shares of Common Stock outstanding immediately after
giving effect to such exercise. For purposes of the foregoing sentence, the
aggregate number of shares of Common Stock beneficially owned by such Person
and its affiliates shall include the number of shares of Common Stock
issuable upon exercise of this Warrant with respect to which the
determination of such sentence is being made, but shall exclude shares of
Common Stock which would be issuable upon (i) exercise of the remaining,
unexercised portion of this Warrant beneficially owned by such Person and
its affiliates and (ii) exercise or conversion of the unexercised or
unconverted portion of any other securities of the Company beneficially
owned by such Person and its affiliates (including, without limitation, any
convertible notes or convertible preferred stock or warrants) subject to a
limitation on conversion or exercise analogous to the limitation contained
herein. Except as set forth in the preceding sentence, for purposes of this
paragraph, beneficial ownership shall be calculated in accordance with
Section 13(d) of the Securities Exchange Act of 1934, as amended. For
purposes of this Warrant, in determining the number of outstanding shares of
Common Stock, the Holder may rely on the number of outstanding shares of
Common Stock as reflected in (1) the Company’s most recent Form 10-K, Form
10-Q, Current Report on Form 8-K or other public filing with the Securities
and Exchange Commission, as the case may be, (2) a more recent public
announcement by the Company or (3) any other notice by the Company or the
Transfer Agent setting forth the number of shares of Common Stock
outstanding. For any reason at any time, upon the written or oral request
of the Holder, the Company shall within one Business Day confirm orally and
in writing to the Holder the number of shares of Common Stock then
outstanding. In any case, the number of outstanding shares of Common Stock
shall be determined after giving effect to the conversion or exercise of
securities of the Company, including the SPA Securities and the SPA
Warrants, by the Holder and its affiliates since the date as of which such
number of outstanding shares of Common Stock was reported. By written
notice to the Company, the Holder may increase or decrease the Maximum
Percentage to any other percentage not in excess of 9.99% specified in such
notice; provided that (i) any such increase will not be effective until the
sixty-first (61st) day after such notice is delivered to the
Company, and (ii) any such increase or decrease will apply only to the
Holder and not to any other holder of SPA Warrants.

3

 

(ii) Principal Market Regulation. The Company shall not be
obligated to issue any shares of Common Stock upon exercise of this Warrant
if the issuance of such Common Stock would exceed that number of shares of
Common Stock which the Company may issue upon exercise of this Warrant
(including, as applicable, any shares of Common Stock issued upon conversion
or exercise of the SPA Securities) without breaching the Company’s
obligations under the rules or regulations of the Principal Market (the
“Exchange Cap”), except that such limitation shall not apply in the event
that the Company (A) obtains the approval of its stockholders as required by
the applicable rules of the Principal Market for issuances of shares of
Common Stock in excess of such amount or (B) obtains a written opinion from
outside counsel to the Company that such approval is not required, which
opinion shall be reasonably satisfactory to the Required Holders. Until
such approval or written opinion is obtained, no Buyer shall be issued, upon
exercise or conversion, as applicable, of any SPA Warrants or SPA
Securities, shares of Common Stock in an amount greater than the product of
the Exchange Cap multiplied by a fraction, the numerator of which is the
total number of shares of Common Stock issued to the Buyer pursuant to the
Securities Purchase Agreement on the Issuance Date and the denominator of
which is the aggregate number of shares of Common Stock issued to the Buyers
pursuant to the Securities Purchase Agreement on the Issuance Date (with
respect to each Buyer, the “Exchange Cap Allocation”). In the event that
any Buyer shall sell or otherwise transfer any of the Buyer’s SPA Warrants,
the transferee shall be allocated a pro rata portion of such Buyer’s
Exchange Cap Allocation, and the restrictions of the prior sentence shall
apply to such transferee with respect to the portion of the Exchange Cap
Allocation allocated to such transferee. In the event that any holder of
SPA Warrants shall exercise all of such holder’s SPA Warrants into a number
of shares of Common Stock which, in the aggregate, is less than such
holder’s Exchange Cap Allocation, then the difference between such holder’s
Exchange Cap Allocation and the number of shares of Common Stock actually
issued to such holder shall be allocated to the respective Exchange Cap
Allocations of the remaining holders of SPA Warrants on a pro rata basis in
proportion to the shares of Common Stock underlying the SPA Warrants then
held by each such holder.

          2. ADJUSTMENT OF EXERCISE PRICE AND NUMBER OF WARRANT SHARES. The Exercise Price and the
number of Warrant Shares shall be adjusted from time to time as follows:

               (i) Adjustment Upon Issuance of Shares of Common Stock. If and whenever on or after
the Subscription Date the Company issues or sells, or in accordance with this Section 2 is deemed
to have issued or sold, any shares of Common Stock (including the issuance or sale of shares of
Common Stock owned or held by or for the account of the Company, but excluding shares of Common
Stock deemed to have been issued by the Company in connection with any Excluded Securities (as
defined in the SPA Securities)) for a consideration per share less than a price (the “Applicable
Price”) equal to the Exercise Price in effect immediately prior to such issue or sale or deemed
issuance or sale (the foregoing a “Dilutive Issuance”), then immediately after such Dilutive
Issuance, the Exercise Price then in effect shall be reduced to an amount equal to the product of
(A) the Exercise Price in effect immediately prior to such Dilutive Issuance and (B) the quotient
determined by dividing (1) the sum of (I) the product derived by multiplying the Exercise Price in
effect immediately prior to such Dilutive Issuance and the number of shares of Common Stock Deemed
Outstanding immediately prior to such Dilutive Issuance plus (II) the consideration, if any,
received by the Company upon such Dilutive Issuance, by (2) the product derived by multiplying (I)
the Exercise Price in effect immediately prior to such Dilutive Issuance by (II) the number of
shares of Common Stock Deemed Outstanding immediately after such Dilutive Issuance. Upon each such
adjustment of the Exercise Price hereunder, the number of Warrant Shares shall be adjusted to the
number of shares of Common Stock determined by multiplying the Exercise Price in effect immediately
prior to such adjustment by the number of Warrant Shares acquirable upon exercise of this Warrant
immediately prior to such adjustment and dividing the product thereof by the Exercise Price
resulting from such adjustment. For purposes of determining the adjusted Exercise Price under this
Section 2(a), the following shall be applicable:

(i) Issuance of Options. If the Company in any manner grants any
Options and the lowest price per share for which one share of Common Stock
is issuable upon the exercise of any such Option or upon conversion,
exercise or exchange of any Convertible

4

 

Securities issuable upon exercise of any such Option is less than the
Applicable Price, then such share of Common Stock shall be deemed to be
outstanding and to have been issued and sold by the Company at the time of
the granting or sale of such Option for such price per share. For purposes
of this Section 2(a)(i), the “lowest price per share for which one share of
Common Stock is issuable upon exercise of such Options or upon conversion,
exercise or exchange of such Convertible Securities” shall be equal to the
sum of the lowest amounts of consideration (if any) received or receivable
by the Company with respect to any one share of Common Stock upon the
granting or sale of the Option, upon exercise of the Option and upon
conversion, exercise or exchange of any Convertible Security issuable upon
exercise of such Option. No further adjustment of the Exercise Price or
number of Warrant Shares shall be made upon the actual issuance of such
            shares of Common Stock or of such Convertible Securities upon the exercise
of such Options or upon the actual issuance of such shares of Common Stock
upon conversion, exercise or exchange of such Convertible Securities.

(ii) Issuance of Convertible Securities. If the Company in any
manner issues or sells any Convertible Securities and the lowest price per
share for which one share of Common Stock is issuable upon the conversion,
exercise or exchange thereof is less than the Applicable Price, then such
share of Common Stock shall be deemed to be outstanding and to have been
issued and sold by the Company at the time of the issuance or sale of such
Convertible Securities for such price per share. For the purposes of this
Section 2(a)(ii), the “lowest price per share for which one share of Common
Stock is issuable upon the conversion, exercise or exchange” shall be equal
to the sum of the lowest amounts of consideration (if any) received or
receivable by the Company with respect to one share of Common Stock upon the
issuance or sale of the Convertible Security and upon conversion, exercise
or exchange of such Convertible Security. No further adjustment of the
Exercise Price or number of Warrant Shares shall be made upon the actual
issuance of such shares of Common Stock upon conversion, exercise or
exchange of such Convertible Securities, and if any such issue or sale of
such Convertible Securities is made upon exercise of any Options for which
adjustment of this Warrant has been or is to be made pursuant to other
provisions of this Section 2(a), no further adjustment of the Exercise Price
or number of Warrant Shares shall be made by reason of such issue or sale.

(iii) Change in Option Price or Rate of Conversion. If the purchase
price provided for in any Options, the additional consideration, if any,
payable upon the issue, conversion, exercise or exchange of any Convertible
Securities, or the rate at which any Convertible Securities are convertible
into or exercisable or exchangeable for shares of Common Stock increases or
decreases at any time, the Exercise Price and the number of Warrant Shares
in effect at the time of such increase or decrease shall be adjusted to the
Exercise Price and the number of Warrant Shares which would have been in
effect at such time had such Options or Convertible Securities provided for
such increased or decreased purchase price, additional consideration or
increased or decreased conversion rate, as the case may be, at the time
initially granted, issued or sold. For purposes of this Section 2(a)(iii),
if the terms of any Option or Convertible Security that was outstanding as
of the date of issuance of this Warrant are increased or decreased in the
manner described in the immediately preceding sentence, then such Option or
Convertible Security and the shares of Common Stock deemed issuable upon
exercise, conversion or exchange thereof shall be deemed to have been issued
as of the date of such increase or decrease. No adjustment pursuant to this
Section 2(a) shall be made if such adjustment would result in an increase of
the Exercise Price then in effect or a decrease in the number of Warrant
Shares.

(iv) Calculation of Consideration Received. In case any Option is
issued in connection with the issue or sale of other securities of the
Company, together comprising one integrated transaction in which no specific
consideration is allocated to such Options

5

 

by the parties thereto, the Options will be deemed to have been issued for a
consideration of $0.01. If any shares of Common Stock, Options or
Convertible Securities are issued or sold or deemed to have been issued or
sold for cash, the consideration received therefor will be deemed to be the
net amount received by the Company therefor. If any shares of Common Stock,
Options or Convertible Securities are issued or sold for a consideration
other than cash, the amount of such consideration received by the Company
will be the fair value of such consideration, except where such
consideration consists of securities which are listed on a securities
exchange or stock market, in which case the amount of consideration received
by the Company will be the Closing Sale Price of such security on the date
of receipt. If any shares of Common Stock, Options or Convertible
Securities are issued to the owners of the non-surviving entity in
connection with any merger in which the Company is the surviving entity, the
amount of consideration therefor will be deemed to be the fair value of such
portion of the net assets and business of the non-surviving entity as is
attributable to such shares of Common Stock, Options or Convertible
Securities, as the case may be. The fair value of any consideration other
than cash or securities will be determined jointly by the Company and the
Required Holders. If such parties are unable to reach agreement within ten
(10) days after the occurrence of an event requiring valuation (the
“Valuation Event”), the fair value of such consideration will be determined
within five (5) Business Days after the tenth day following the Valuation
Event by an independent, reputable appraiser jointly selected by the Company
and the Required Holders. The determination of such appraiser shall be
final and binding upon all parties absent manifest error and the fees and
expenses of such appraiser shall be borne by the Company.

(v)
Record Date. If the Company takes a record of the holders of shares of Common Stock for the purpose of entitling them (A) to receive a
dividend or other distribution payable in shares of Common Stock, Options or
in Convertible Securities or (B) to subscribe for or purchase shares of
Common Stock, Options or Convertible Securities, then such record date will
be deemed to be the date of the issue or sale of the shares of Common Stock
deemed to have been issued or sold upon the declaration of such dividend or
the making of such other distribution or the date of the granting of such
right of subscription or purchase, as the case may be.

               (ii) Adjustment upon Subdivision or Combination of Shares of Common Stock. If the
Company at any time on or after the Subscription Date subdivides (by any stock split, stock
dividend, recapitalization or otherwise) one or more classes of its outstanding shares of Common
Stock into a greater number of shares, the Exercise Price in effect immediately prior to such
subdivision will be proportionately reduced and the number of Warrant Shares will be
proportionately increased. If the Company at any time on or after the Subscription Date combines
(by combination, reverse stock split or otherwise) one or more classes of its outstanding shares of
Common Stock into a smaller number of shares, the Exercise Price in effect immediately prior to
such combination will be proportionately increased and the number of Warrant Shares will be
proportionately decreased. Any adjustment under this Section 2(b) shall become effective at the
close of business on the date the subdivision or combination becomes effective.

               (iii) Other Events. If any event occurs of the type contemplated by the provisions of
this Section 2 but not expressly provided for by such provisions (including, without limitation,
the granting of stock appreciation rights, phantom stock rights or other rights with equity
features), then the Company’s Board of Directors will make an appropriate adjustment in the
Exercise Price and the number of Warrant Shares so as to protect the rights of the Holder; provided
that no such adjustment pursuant to this Section 2(c) will increase the Exercise Price or decrease
the number of Warrant Shares as otherwise determined pursuant to this Section 2.

6

 

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

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

               (ii) the number of Warrant Shares shall be increased to a number of shares equal to the number
of shares of Common Stock obtainable immediately prior to the close of business on the record date
fixed for the determination of holders of shares of Common Stock entitled to receive the
Distribution multiplied by the reciprocal of the fraction set forth in the immediately preceding
paragraph (a); provided that in the event that the Distribution is of shares of Common Stock (or
common stock) (“Other Shares of Common Stock”) of a company whose common shares are traded on a
national securities exchange or a national automated quotation system, then the Holder may elect to
receive a warrant to purchase Other Shares of Common Stock in lieu of an increase in the number of
Warrant Shares, the terms of which shall be identical to those of this Warrant, except that such
warrant shall be exercisable into the number of shares of Other Shares of Common Stock that would
have been payable to the Holder pursuant to the Distribution had the Holder exercised this Warrant
immediately prior to such record date and with an aggregate exercise price equal to the product of
the amount by which the exercise price of this Warrant was decreased with respect to the
Distribution pursuant to the terms of the immediately preceding paragraph (a) and the number of
Warrant Shares calculated in accordance with the first part of this paragraph (b).

          4. PURCHASE RIGHTS; FUNDAMENTAL TRANSACTIONS.

          (i) Purchase Rights. In addition to any adjustments pursuant to Section 2 above, if
at any time the Company grants, issues or sells any Options, Convertible Securities or rights to
purchase stock, warrants, securities or other property pro rata to the record holders of any class
of shares of Common Stock (the “Purchase Rights”), then the Holder will be entitled to acquire,
upon the terms applicable to such Purchase Rights, the aggregate Purchase Rights which the Holder
could have acquired if the Holder had held the number of shares of Common Stock acquirable upon
complete exercise of this Warrant (without regard to any limitations on the exercise of this
Warrant) immediately before the date on which a record is taken for the grant, issuance or sale of
such Purchase Rights, or, if no such record is taken, the date as of which the record holders of
shares of Common Stock are to be determined for the grant, issue or sale of such Purchase Rights.

          (ii) Fundamental Transactions. The Company shall not enter into or be party to a
Fundamental Transaction unless (i) the Successor Entity assumes in writing all of the obligations
of the Company under this Warrant and the other Transaction Documents in accordance with the
provisions of this Section (4)(b) pursuant to written agreements in form and substance satisfactory
to the Required Holders and approved by the Required Holders prior to such Fundamental Transaction,
including agreements to deliver to each holder of Warrants in exchange for such Warrants a security
of the Successor Entity evidenced by a written instrument substantially similar in form and
substance to this Warrant, including, without limitation, an adjusted exercise price equal to the
value for the shares of Common Stock reflected by the terms of such Fundamental Transaction, and
exercisable for a corresponding number of shares of capital stock equivalent to the shares of
Common Stock acquirable and receivable upon exercise of this Warrant (without regard to any
limitations on the exercise of this Warrant) prior to such Fundamental Transaction, and
satisfactory to the Required Holders and (ii) the Successor Entity (including its Parent Entity) is
a publicly traded corporation whose common stock is quoted on or listed for trading on an Eligible
Market. Upon the occurrence of any Fundamental Transaction, the Successor Entity shall succeed to,
and be substituted for (so that from and after the date of such Fundamental Transaction, the
provisions of

7

 

this Warrant referring to the “Company” shall refer instead to the Successor Entity), and may
exercise every right and power of the Company and shall assume all of the obligations of the
Company under this Warrant with the same effect as if such Successor Entity (including its Parent
Entity) had been named as the Company herein. Upon consummation of the Fundamental Transaction,
the Successor Entity shall deliver to the Holder confirmation that there shall be issued upon
exercise of this Warrant at any time after the consummation of the Fundamental Transaction, in lieu
of the shares of the Common Stock (or other securities, cash, assets or other property) purchasable
upon the exercise of the Warrant prior to such Fundamental Transaction, such shares of the publicly
traded common stock (or its equivalent) of the Successor Entity (including its Parent Entity), as
adjusted in accordance with the provisions of this Warrant. In addition to and not in substitution
for any other rights hereunder, prior to the consummation of any Fundamental Transaction pursuant
to which holders of shares of Common Stock are entitled to receive securities or other assets with
respect to or in exchange for shares of Common Stock (a “Corporate Event”), the Company shall make
appropriate provision to insure that the Holder will thereafter have the right to receive upon an
exercise of this Warrant at any time after the consummation of the Fundamental Transaction but
prior to the Expiration Date, in lieu of the shares of the Common Stock (or other securities, cash,
assets or other property) purchasable upon the exercise of the Warrant prior to such Fundamental
Transaction, such shares of stock, securities, cash, assets or any other property whatsoever
(including warrants or other purchase or subscription rights) which the Holder would have been
entitled to receive upon the happening of such Fundamental Transaction had the Warrant been
exercised immediately prior to such Fundamental Transaction. Provision made pursuant to the
preceding sentence shall be in a form and substance reasonably satisfactory to the Required
Holders. The provisions of this Section shall apply similarly and equally to successive
Fundamental Transactions and Corporate Events and shall be applied without regard to any
limitations on the exercise of this Warrant.

               (iii) Notwithstanding the foregoing and the provisions of Section 4(b) above, in the event of
a Fundamental Transaction, if the Holder has not exercised the Warrant in full prior to the
consummation of the Fundamental Transaction, then the Holder shall have the right to require such
Successor Entity to purchase this Warrant from the Holder by paying to the Holder, simultaneously
with the consummation of the Fundamental Transaction and in lieu of the warrant referred to in
Section 4(b), cash in an amount equal to the value of the remaining unexercised portion of this
Warrant on the date of such consummation, which value shall be determined by use of the Black and
Scholes Option Pricing Model reflecting (i) a risk-free interest rate corresponding to the U.S.
Treasury rate for a period equal to the remaining term of this Warrant as of such date of request
and (ii) an expected volatility equal to the greater of 60% and the 100 day volatility obtained
from the HVT function on Bloomberg.

          F. NONCIRCUMVENTION. The Company hereby covenants and agrees that the Company will
not, by amendment of its Articles of Incorporation, Bylaws or through any reorganization, transfer
of assets, consolidation, merger, scheme of arrangement, dissolution, issue or sale of securities,
or any other voluntary action, avoid or seek to avoid the observance or performance of any of the
terms of this Warrant, and will at all times in good faith carry out all the provisions of this
Warrant and take all action as may be required to protect the rights of the Holder. Without
limiting the generality of the foregoing, the Company (i) shall not increase the par value of any
shares of Common Stock receivable upon the exercise of this Warrant above the Exercise Price then
in effect, (ii) shall take all such actions as may be necessary or appropriate in order that the
Company may validly and legally issue fully paid and nonassessable shares of Common Stock upon the
exercise of this Warrant, and (iii) shall, so long as any of the SPA Warrants are outstanding, take
all action necessary to reserve and keep available out of its authorized and unissued shares of
Common Stock, solely for the purpose of effecting the exercise of the SPA Warrants, 150% of the
number of shares of Common Stock as shall from time to time be necessary to effect the exercise of
the SPA Warrants then outstanding (without regard to any limitations on exercise).

          5. WARRANT HOLDER NOT DEEMED A STOCKHOLDER. Except as otherwise specifically provided
herein, the Holder, solely in such Person’s capacity as a holder of this Warrant, shall not be
entitled to vote or receive dividends or be deemed the holder of share capital of the Company for
any purpose, nor shall anything contained in this Warrant be construed to confer upon the Holder,
solely in such Person’s capacity as the Holder of this Warrant, any of the rights of a shareholder
of the Company or any right to vote, give or withhold consent to any corporate action (whether any
reorganization, issue of stock, reclassification of stock, consolidation, merger, conveyance or
otherwise), receive notice of meetings, receive dividends or subscription rights, or otherwise,
prior to the issuance to the Holder of the Warrant Shares which such Person is then entitled to
receive upon the due exercise of this Warrant. In addition, nothing contained in this Warrant
shall be construed as imposing any liabilities on the Holder to purchase any securities (upon
exercise of this Warrant or otherwise) or as a shareholder

8

 

of the Company, whether such liabilities are asserted by the Company or by creditors of the
Company. Notwithstanding this Section 6, the Company shall provide the Holder with copies of the
same notices and other information given to the shareholders of the Company generally,
contemporaneously with the giving thereof to the shareholders.

          6. REISSUANCE OF WARRANTS.

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

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

               (iii) Exchangeable for Multiple Warrants. This Warrant is exchangeable, upon the
surrender hereof by the Holder at the principal office of the Company, for a new Warrant or
Warrants (in accordance with Section 7(d)) representing in the aggregate the right to purchase the
number of Warrant Shares then underlying this Warrant, and each such new Warrant will represent the
right to purchase such portion of such Warrant Shares as is designated by the Holder at the time of
such surrender; provided, however, that no Warrants for fractional shares of Common Stock shall be
given.

               (iv) Issuance of New Warrants. Whenever the Company is required to issue a new
Warrant pursuant to the terms of this Warrant, such new Warrant (i) shall be of like tenor with
this Warrant, (ii) shall represent, as indicated on the face of such new Warrant, the right to
purchase the Warrant Shares then underlying this Warrant (or in the case of a new Warrant being
issued pursuant to Section 7(a) or Section 7(c), the Warrant Shares designated by the Holder which,
when added to the number of shares of Common Stock underlying the other new Warrants issued in
connection with such issuance, does not exceed the number of Warrant Shares then underlying this
Warrant), (iii) shall have an issuance date, as indicated on the face of such new Warrant which is
the same as the Issuance Date, and (iv) shall have the same rights and conditions as this Warrant.

          7. NOTICES. Whenever notice is required to be given under this Warrant, unless
otherwise provided herein, such notice shall be given in accordance with Section 9(f) of the
Securities Purchase Agreement. The Company shall provide the Holder with prompt written notice of
all actions taken pursuant to this Warrant, including in reasonable detail a description of such
action and the reason therefore. Without limiting the generality of the foregoing, the Company
will give written notice to the Holder (i) immediately upon any adjustment of the Exercise Price,
setting forth in reasonable detail, and certifying, the calculation of such adjustment and (ii) at
least fifteen days prior to the date on which the Company closes its books or takes a record (A)
with respect to any dividend or distribution upon the shares of Common Stock, (B) with respect to
any grants, issuances or sales of any Options, Convertible Securities or rights to purchase stock,
warrants, securities or other property to holders of shares of Common Stock or (C) for determining
rights to vote with respect to any Fundamental Transaction, dissolution or liquidation, provided in
each case that such information shall be made known to the public prior to or in conjunction with
such notice being provided to the Holder.

          8. AMENDMENT AND WAIVER. Except as otherwise provided herein, the provisions of this
Warrant may be amended and the Company may take any action herein prohibited, or omit to perform
any act herein required to be performed by it, only if the Company has obtained the written consent
of the Required Holders; provided that no such action may increase the exercise price of any SPA
Warrant or decrease the number of shares or class of stock obtainable upon exercise of any SPA
Warrant without the written consent of the Holder. No such amendment shall be effective to the
extent that it applies to less than all of the holders of the SPA Warrants then outstanding.

9

 

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

          10. CONSTRUCTION; HEADINGS. This Warrant shall be deemed to be jointly drafted by the
Company and all the Buyers and shall not be construed against any person as the drafter hereof.
The headings of this Warrant are for convenience of reference and shall not form part of, or affect
the interpretation of, this Warrant.

          11. DISPUTE RESOLUTION. In the case of a dispute as to the determination of the
Exercise Price or the arithmetic calculation of the Warrant Shares, the Company shall submit the
disputed determinations or arithmetic calculations via facsimile within two Business Days of
receipt of the Exercise Notice giving rise to such dispute, as the case may be, to the Holder. If
the Holder and the Company are unable to agree upon such determination or calculation of the
Exercise Price or the Warrant Shares within three Business Days of such disputed determination or
arithmetic calculation being submitted to the Holder, then the Company shall, within two Business
Days submit via facsimile (a) the disputed determination of the Exercise Price to an independent,
reputable investment bank selected by the Company and approved by the Holder or (b) the disputed
arithmetic calculation of the Warrant Shares to the Company’s independent, outside accountant. The
Company shall cause at its expense the investment bank or the accountant, as the case may be, to
perform the determinations or calculations and notify the Company and the Holder of the results no
later than ten Business Days from the time it receives the disputed determinations or calculations.
Such investment bank’s or accountant’s determination or calculation, as the case may be, shall be
binding upon all parties absent demonstrable error.

          12. REMEDIES, OTHER OBLIGATIONS, BREACHES AND INJUNCTIVE RELIEF. The remedies
provided in this Warrant shall be cumulative and in addition to all other remedies available under
this Warrant and the other Transaction Documents, at law or in equity (including a decree of
specific performance and/or other injunctive relief), and nothing herein shall limit the right of
the Holder right to pursue actual damages for any failure by the Company to comply with the terms
of this Warrant. The Company acknowledges that a breach by it of its obligations hereunder will
cause irreparable harm to the Holder and that the remedy at law for any such breach may be
inadequate. The Company therefore agrees that, in the event of any such breach or threatened
breach, the holder of this Warrant shall be entitled, in addition to all other available remedies,
to an injunction restraining any breach, without the necessity of showing economic loss and without
any bond or other security being required.

          13. TRANSFER. This Warrant may be offered for sale, sold, transferred or assigned
without the consent of the Company, except as may otherwise be required by Section 2(f) of the
