This AGREEMENT AND PLAN OF MERGER dated as of
February 3, 2008 (this “Agreement”) is made and entered into by and
among Progen Pharmaceuticals Limited, a company organized under the laws of
Queensland, Australia (“Parent”), Progen Pharmaceuticals, Inc., a
Delaware corporation and a wholly owned subsidiary of Parent (“Sub”),
CellGate, Inc., a Delaware corporation (the “Company”), and SPROUT
CAPITAL IX, L.P., a Delaware limited partnership (the “Representative”),
solely with respect to Article II hereof and such other provisions hereof
which specifically refer to such Representative.


 


WHEREAS, the Company has its principal place
of business at 3 Twin Dolphin Drive, Redwood City, California 94065, USA, and
is a development stage biotech company whose mission is to develop and market
novel small molecule therapeutics for the treatment of cancer and related
conditions; and


 


WHEREAS, Parent has its registered office at
16 Benson Street, Toowong, Queensland 4066, Australia, and is committed to
developing and commercializing novel small molecule therapeutics for the
treatment of cancer and related conditions; and


 


WHEREAS, Sub was formed so that it would
merge with and into the Company; and


 


WHEREAS, the respective Boards of Directors
of each of Parent, Sub and the Company have determined that the merger of the
Sub with and into the Company (the “Merger”) in accordance with the
provisions of the Delaware General Corporation Law, as amended (the “DGCL”),
and subject to the terms and conditions of this Agreement, is advisable and in
the best interests of the Parent, Sub and the Company and their respective
stockholders and have approved this Agreement and the transactions contemplated
hereby; and


 


WHEREAS, Parent, Sub and the Company desire
to make certain representations, warranties, covenants and agreements in
connection with the Merger and also to prescribe various conditions to the
Merger.


 


NOW, THEREFORE, in consideration of the
mutual covenants and agreements set forth in this Agreement, and for other good
and valuable consideration, the receipt and sufficiency of which are hereby
acknowledged, the parties hereto agree as follows:


 


ARTICLE I


 


THE MERGER


 


1.01.        The
Merger. At the Effective Time (as defined in Section 1.02), upon the terms
and subject to the conditions of this Agreement, the Sub shall be merged with
and into the Company in accordance with the DGCL. The Company shall be the
surviving corporation in the Merger (the “Surviving Corporation”) and
shall be renamed Progen Pharmaceuticals, Inc. Sub and the Company are
sometimes referred to herein as the “Constituent Corporations.” As a
result of the Merger, the outstanding shares of capital stock of the
Constituent Corporations shall be converted or canceled in the manner provided
in Article II.


 
















 


1.02.        Effective Time. At the Closing (as defined in Section 1.03), a
certificate of merger (the “Certificate of Merger”) shall be duly
prepared and executed by the Surviving Corporation and thereafter delivered to
the Secretary of State of the State of Delaware (the “Secretary of State”)
for filing, as provided in Section 251 of the DGCL, on, or as soon as
practicable after, the Closing Date (as defined in Section 1.03). The
Merger shall become effective at the time of the filing of the Certificate of
Merger with the Secretary of State (such time and date being referred to herein
as the “Effective Time”).


 


1.03.        Closing. The closing of the Merger (the “Closing”) will take place
in San Francisco, California, or at such other place as the parties hereto
mutually agree, on a date and at a time to be specified by the parties, which
shall in no event be later than 10:00 a.m., local time, on the second
business day following satisfaction of the conditions set forth in Article VIII
or, if permissible, waived in accordance with this Agreement, or on such other
date and time as the parties hereto may mutually agree (the “Closing Date”).
At the Closing there shall be delivered to Parent, Sub and the Company the
certificates and other documents and instruments required to be delivered under
Article VIII.


 


1.04.        Certificate of Incorporation and Bylaws of the Surviving Corporation. At
the Effective Time, (i) the Certificate of Incorporation of the Surviving
Corporation shall be amended and restated so that it shall be the same as the
Certificate of Incorporation of Sub as in effect immediately prior to the
Effective Time and it shall be the Certificate of Incorporation of the
Surviving Corporation until thereafter amended as provided by law and such
Certificate of Incorporation and (ii) the Bylaws of Sub as in effect
immediately prior to the Effective Time shall be the Bylaws of the Surviving
Corporation until thereafter amended as provided by law, the Certificate of
Incorporation of the Surviving Corporation and such Bylaws.


 


1.05.        Directors and Officers of the Surviving Corporation. The directors of Sub
immediately prior to the Effective Time shall, from and after the Effective
Time, be the directors and officers, respectively, of the Surviving Corporation
until their successors shall have been duly elected or appointed and qualified
or until their earlier death, resignation or removal in accordance with the
Surviving Corporation’s Certificate of Incorporation and Bylaws.


 


1.06.        Effects of the Merger. Subject to the foregoing, the effects of the
Merger shall be as provided in the applicable provisions of the DGCL.


 


ARTICLE II


 


CONVERSION OF SHARES


 


2.01.        Conversion of Capital Stock. At the Effective Time, by virtue of the
Merger and without any action on the part of the holder thereof:


 


(a)           Capital Stock of Sub. Each issued and outstanding share of the common
stock, par value US$0.001 per share, of Sub (“Sub Common Stock”) shall
be converted into and become one fully paid and nonassessable share of common
stock, par value US$0.001 per share, of the Surviving Corporation (“Surviving
Corporation Common Stock”). Each certificate


 


2

















 


representing outstanding shares of Sub Common
Stock shall, without further action by the holder thereof at the Effective Time
represent shares of Surviving Corporation Common Stock.


 


(b)           Cancellation of Treasury Stock and Stock Owned by
Parent and Subsidiaries. All
shares of common stock of the Company, par value US$0.001 per share (“Company
Common Stock”), that are owned by the Company as treasury stock or
otherwise and any shares of Company Common Stock owned by Parent, Sub or any
other direct or indirect wholly-owned Subsidiary (as hereinafter defined) of
Parent shall be canceled and retired and shall cease to exist and no capital
stock of the Surviving Corporation or any other consideration shall be
delivered in exchange therefor. As used in this Agreement, the term “Subsidiary”
means, with respect to any party, any corporation or other organization, whether
incorporated or unincorporated, of which more than fifty percent (50%) of
either the equity interests in, or the voting control of, such corporation or
other organization is, directly or indirectly through Subsidiaries or
otherwise, beneficially owned by such party.


 


(c)           Exchange; Adjustment. (i) The consideration hereunder shall consist
of 756,199 validly issued, fully paid and nonassessable, ordinary shares of
Parent (“Parent Shares”), subject to adjustment as set forth in this Section 2.01.
Each issued and outstanding share of Company Common Stock (other than shares to
be canceled in accordance with Section 2.01(b)) and other than Dissenting
Shares (as defined in Section 2.01(d)), each issued and outstanding share
of the Series A Preferred Stock, US$0.001 par value (the “Series A
Preferred Stock”), of the Series B Preferred Stock, US$0.001 par value
(the “Series B Preferred Stock”) and of the Series C Preferred
Stock, US$0.001 par value (the “Series C Preferred Stock,” and
together with the Series A Preferred Stock and the Series B Preferred
Stock, collectively, the “Preferred Stock”) and each issued and
outstanding share of the Series D Preferred Stock, US$0.001 par value (the
“Series D Preferred Stock”) and of the Series E Preferred
Stock, US$0.001 par value (the “Series E Preferred Stock,” and
together with the Series D Preferred Stock, collectively, the “Senior
Preferred Stock”) shall be converted into Parent Shares in accordance with Article IV,
Section D.3. of the Fifth Amended and Restated Certificate of
Incorporation of the Company, as in effect on the date hereof and a copy of
which has been made available to Parent or its counsel, subject to adjustment
in accordance with this Section 2.01(c). The Parent Shares so issued shall
be registered and freely tradeable on the Australian Securities Exchange
without restriction no later than 45 days following the issuance thereof.


 


(i)            If, prior to the Effective Time, Parent shall pay a
dividend in (including any dividend or distribution of securities convertible
into capital stock), subdivide, combine into a smaller number of shares or
issue by reclassification of its shares, any Parent Shares, all references in
this Agreement to specified numbers of shares of Parent Shares affected
thereby, and all calculations provided for that are based upon numbers of
Parent Shares (or trading prices therefor) affected thereby, shall be equitably
adjusted to the extent necessary to provide the parties the same economic
effect as contemplated by this Agreement prior such adjustment. All such shares
of Company Common Stock, Preferred Stock and Senior Preferred Stock, other than
Dissenting Shares (as defined in Section 2.01(d)), shall no longer be
outstanding and be automatically canceled and retired and shall cease to exist,
and each holder of a certificate representing shares of Company Common Stock,
Preferred Stock or Senior Preferred Stock, as the case may be, shall cease to
have any rights with respect thereto, except the right of such holder to
receive


 


3

















 


the applicable number of Parent Shares or
cash, as the case may be, upon the surrender of such certificate in accordance
with Section 2.02, without interest, and such holder’s right to receive
cash or Parent Shares upon the achievement of the Milestones.


 


(ii)           The number of Parent Shares to be paid at the
Closing Date (the “Parent Share Consideration”) is based on the
assumption that the Net Liabilities were not more than US$1,000,000 on the
business day prior to the Closing Date. The Company will cause (A) the
accounting records of the Company to be closed as of the close of business on
the business day preceding the Closing Date and (B) a balance sheet to be
prepared in accordance with GAAP (except that such balance sheet shall not
contain the footnotes required by GAAP) as of such time (the “Closing Date
Balance Sheet”). The Closing Date Balance Sheet shall reflect all events
occurring through the close of business on the business day preceding the
Closing Date, and will include the Net Liabilities as at such date. Parent
shall have full access to accounting records, trial balances and reports from
which the Net Liabilities computation was derived.


 


(iii)          If, as set forth in the Closing Date Balance Sheet,
the Net Liabilities were more than US$1,000,000 on the business day prior to
the Closing Date, the Parent Share Consideration shall be reduced by the amount
of such deficiencies as calculated pursuant to this Section 2.01. If, as
set forth in the Closing Date Balance Sheet, the Net Liabilities are less than
US$1,0000,000, the Parent Share Consideration shall be increased by the amount
of such excess cash and/or the amount of lesser debt as calculated pursuant to
this Section 2.01, but in no event in excess of 957,464 Parent Shares. Any
remaining difference where such Net Liabilities are less than US$1,000,000 will
be paid in cash in U.S. Dollars by the Parent. In making any reduction or
increase in the Parent Shares, the value of each Parent Share shall be
converted into U.S. Dollars using the Exchange Rate for the purposes of such
calculation.


 


(iv)          If, within 45 calendar days after the Company’s
delivery of the computation of the Net Liabilities to Parent pursuant to this
Section, Parent determines in good faith that the amount of the Net Liabilities
so computed is inaccurate, Parent shall give notice to the Representative
within such 45 calendar-day period, (A) setting forth Parent’s
determination of the amount of the Net Liabilities and (B) specifying in
reasonable detail Parent’s basis for its disagreement with the Company’s
computation. The failure by Parent so to express its disagreement within such
45 calendar-day period shall constitute acceptance of the amount of the Net
Liabilities shown on the Closing Date Balance Sheet for all purposes of this
Section. A representative of Parent and the Representative shall attempt in
good faith to resolve any such disputes. If the Representative and Parent are
unable to resolve any disagreement with respect to these computations within 30
calendar days after receipt by the Representative of notice of such
disagreement, the items in dispute shall be referred for determination to a “Big
4” independent accounting firm agreed upon by the Representative and Parent
(the “Accountants”) within such 30 calendar-day period. The Accountants
shall make a determination as to each of the items in dispute, which
determination shall be (W) in writing, (X) furnished to the
Representative and Parent as promptly as practicable after the items in dispute
have been referred to the Accountants, (Y) made in accordance with GAAP
and (Z) conclusive and binding on the Parent. The fees and expenses of the


 


4

















 


Accountants shall be paid by Parent;
provided, however, that Parent shall be reimbursed for one-half of such fees
and expenses out of the Parent Share Consideration. As soon as reasonably
practicable after the final resolution of the computation of the Net
Liabilities in accordance with this Section 2.01(c), the Parent shall
cause the Exchange Agent to issue to holders of surrendered Certificates, in
accordance with Section 2.02, holding statements reflecting the shares
registered on the books of the Parent representing that number of additional
duly and validly authorized Parent Shares which such holders have the right to
receive pursuant to the provisions of this Article II, if any, after
adjustment to reflect the final computation of the Net Liabilities and any fees
and expenses owing pursuant to this Section 2.01(c) and the Holdback
Shares, and shall pay any amount of cash payable pursuant to Section 2.01(c)(iii).


 


(v)           By virtue of the approval of this Agreement by the
Company’s stockholders, and without further action of any Company stockholder,
each Company stockholder entitled to receive Parent Shares under this Agreement
shall be deemed to have irrevocably constituted and appointed Sprout Capital
IX, L.P. (and by execution and delivery of this Agreement it hereby accepts
such appointment) as agent and attorney-in-fact for and on behalf of such
stockholders, with full power of substitution, to act in the name, place and
stead of each such stockholder with respect to this Section 2.01(c) in
connection with the determination of the Net Liabilities and the taking by the
Representative of any and all actions and the making of any decisions required
or permitted to be taken by the Representative under this Article II,
including the exercise of the power to: (i) give and receive notices and
communications under this Article II; (ii) prepare and deliver to
Parent the Closing Date Balance Sheet and computation of Net Liabilities and
participate on behalf of the Company’s stockholders in the resolution of any
dispute relating thereto, including to act as the representative of the Company’s
stockholders to review and authorize all adjustments proposed hereunder and
dispute or question the accuracy thereof and to compromise on their behalf with
Parent; (iii) deliver or authorize the delivery of any consideration owing
pursuant to this Agreement; and (iv) take all actions necessary or
appropriate in the good faith judgment of the Representative for the
accomplishment of the foregoing. The power of attorney granted in this Section 2.01(c) is
coupled with an interest and is irrevocable, and shall survive the death or
incapacity of any Company stockholder. The Parent shall be entitled to deal
exclusively with the Representative on all such foregoing matters, and shall be
entitled to rely conclusively (without further evidence of any kind whatsoever)
on any document executed or purported to be executed on behalf of the Company
stockholders by the Representative regarding such matters, and on any other
action taken or purported to be taken on behalf of any Company stockholder by
the Representatives regarding such matters, as fully binding upon such Company
stockholder. No bond shall be required of the Representative, and the
Representative shall receive no compensation for services. Notices or
communications to or from the Representative shall constitute notice to or from
each of the Company’s stockholders.


 


(vi)          In performing the functions specified in this
Agreement, the Representative shall not be liable to any Company Stockholder in
the absence of gross negligence or willful misconduct on the part of the
Representative. The Representative shall not be liable to Parent for any
damages resulting from any claim because of such


 


5

















 


Representative’s position as the
Representative. Each of the Company’s stockholders shall severally (based on
each such stockholder’s pro rata share of the consideration owing pursuant to
this Agreement), and not jointly, indemnify and hold harmless the
Representative from and against any loss, liability or expense incurred without
gross negligence or willful misconduct on the part of the Representative and
arising out of or in connection with the acceptance or administration of the
Representative’s duties hereunder, including any out-of-pocket costs and expenses
and legal fees and other legal costs reasonably incurred by the Representative.


 


(d)           Dissenting Shares. (i) Notwithstanding any provision of this
Agreement to the contrary, each outstanding share of Company Common Stock,
Preferred Stock and Senior Preferred Stock, the holder of which has not voted
in favor of the Merger, has perfected such holder’s right to an appraisal of
such holder’s shares in accordance with the applicable provisions of the DGCL
and has not effectively withdrawn or lost such right to appraisal or is
entitled to and properly exercises dissenters rights pursuant to, and complies
with, Chapter 13 of the CGCL (each, a “Dissenting Share”), shall not be
converted into or represent the right to receive Parent Shares and cash
pursuant to Section 2.01(c) and such number of Parent Shares and cash
shall revert to Parent, but the holder thereof shall be entitled only to such
rights as are granted by the applicable provisions of the DGCL and the CGCL; provided,
however, that any Dissenting Share held by a person at the Effective
Time who shall, after the Effective Time, withdraw the demand for appraisal or
lose the right of appraisal, in either case pursuant to the DGCL, shall be
deemed to be converted into, as of the Effective Time, the right to receive the
appropriate number of Parent Shares and cash, as the case may be, pursuant to Section 2.01(c).


 


(ii)           The Company shall give Parent (x) prompt
notice of any written demands for appraisal, withdrawals of demands for
appraisal and any other instruments served pursuant to the applicable
provisions of the DGCL or CGCL relating to the appraisal process received by

applicable. The Company will not voluntarily make any payment with respect to
any demands for appraisal and will not, except with the prior written consent
of Parent, settle or offer to settle any such demands.


 


(e)           Company Stock Options and Warrants. On the Closing Date, each outstanding
option to purchase a share of Company Common Stock (a “Company Stock Option”)
and warrant to purchase a share of Company Common Stock (a “Company Warrant”)
that has been timely exercised shall be converted into Parent Shares and cash,
as the case may be, in accordance with Section 2.01(c)(i). On the Closing
Date, all Company Stock Options and Company Warrants not exercised before the
Closing Date shall no longer be outstanding and shall automatically be canceled
and cease to exist.


 


(f)            Holdback. At Closing 151,240 (comprising twenty
percent (20%)) of the Parent Shares issuable pursuant to Section 2.01(c)(collectively,
the “Holdback Shares”) shall be retained by Parent pursuant to Section 11.02(c).


 


(g)           Further Assurances. If, at any time before or after the Effective Time,
any of the parties hereto reasonably believes or is advised that any further
instruments, deeds, assignments


 


6

















 


or assurances are reasonably necessary to
consummate the Merger or to carry out the purposes and intent of this Agreement
at or after the Effective Time, then the Company, Parent, the Surviving
Corporation and their respective officers and directors shall execute and
deliver all such proper deeds, assignments, instruments and assurances and do
all other things reasonably necessary to consummate the Merger and to carry out
the purposes and intent of this Agreement.


 


2.02.       Exchange of Certificates.


 


(a)           Exchange Agent. At Closing Parent shall make available to the Surviving
Corporation for deposit with an exchange agent reasonably acceptable to Parent,
the Company and the Representative (the “Exchange Agent”) on behalf of
Parent, holding statements issued by the Parent’s share transfer agent
representing 604,959 duly and validly authorized and issued whole Parent Shares
to be held for the benefit of holders of Company Common Stock, Preferred Stock
and Senior Preferred Stock. The Parent shall holdback 151,240 Parent Shares as “Holdback
Shares”. Immediately following conclusion of the procedures contemplated by Section 2.01(c)(iv) above,
cash (if then payable) and holding statements issued by the Parent’s share
transfer agent representing the remaining Parent Shares then payable shall be
deposited with the Exchange Agent for the benefit of holders of Company Common
Stock, Preferred Stock and Senior Preferred Stock. The Exchange Agent shall
agree to hold such cash and Parent Shares (such cash and Parent Shares being
referred to herein as the “Exchange Fund”) as contemplated by this Section and
upon such additional terms as may be agreed upon by the Exchange Agent, the
Company and Parent before the Effective Time.


 


(b)           Exchange Procedures. As soon as reasonably practicable after the
Effective Time, the Surviving Corporation on behalf of Parent shall cause the
Exchange Agent to mail to each holder of record of a certificate or
certificates which immediately prior to the Effective Time represented
outstanding shares of Company Common Stock, Preferred Stock or Senior Preferred
Stock (the “Certificates”) whose shares are converted pursuant to Section 2.01(c) into
the right to receive Parent Shares (i) a letter of transmittal (which
shall specify that delivery shall be effected, and risk of loss and title to
the Certificates shall pass, only upon delivery of the Certificates to the
Exchange Agent and shall be in such form and have such other customary
provisions as the Surviving Corporation may reasonably specify) and (ii) instructions
for use in effecting the surrender of the Certificates in exchange for Parent
Shares and cash. Upon surrender of a Certificate for cancellation to the
Exchange Agent, together with such letter of transmittal duly executed and
completed in accordance with its terms, the holder of such Certificate shall be
entitled to receive in exchange therefore a holding statement representing
shares registered on the books of the Parent representing that number of duly
and validly authorized Parent Shares which such holder has the right to receive
at Closing pursuant to the provisions of this Article II. Thereafter,
subject to completion of the procedures specified in Section 2.01(c)(iv),
and less the Holdback Shares, such holder shall be entitled to receive a
holding statement representing the additional Parent Shares and cash, if any,
which such holder has the right to receive after final resolution of the Net
Liabilities and any increases or decreases in the Parent Share Consideration in
accordance with Section 2.01(c), as adjusted, and the Certificate so
surrendered shall forthwith be canceled. In the event of a transfer of
ownership of Company Common Stock, Preferred Stock or Senior Preferred Stock
which is not registered in the transfer records of the Company, a holding
statement representing the appropriate number of whole Parent Shares may be
issued to a transferee if the Certificate representing such Company


 


7

















 


Common Stock, Preferred Stock or Senior
Preferred Stock is presented to the Exchange Agent accompanied by all documents
required to evidence and effect such transfer and by evidence that any
applicable stock transfer taxes have been paid and that all applicable United
States and Australian federal or state securities laws have been complied with.
Until surrendered as contemplated by this Section 2.02(b), each
Certificate shall be deemed at any time after the Effective Time for all
corporate purposes of Parent, except as limited by paragraph (c) below, to
represent ownership of the number of duly and validly authorized Parent Shares
into which the number of shares of Company Common Stock, Preferred Stock or
Senior Preferred Stock, as the case may be, shown thereon have been converted
as contemplated by this Article II. In the event any Certificate shall
have been lost, stolen or destroyed, upon the making of an affidavit of that
fact by the Person claiming such Certificate to be lost, stolen or destroyed,
Parent shall, as promptly as practicable following the receipt by Parent of the
foregoing documents, issue in exchange for such lost, stolen or destroyed
Certificate that portion of the Parent Shares represented by the lost, stolen
or destroyed Certificate in exchange therefore which the Company’s stockholder
has the right to receive. The Board of Directors of Parent may in its
discretion and as a condition precedent to the issuance thereof, require the
owner of such lost, stolen or destroyed Certificate to provide to Parent an
indemnity agreement, but not a bond, against any claim that may be made against
Parent with respect to the Certificate alleged to have been lost, stolen or
destroyed.


 


(c)           Distributions with Respect to Unexchanged Shares. No dividends or other
distributions declared or made after the Effective Time with respect to Parent
Shares with a record date on or after the Effective Time shall be paid to the
holder of any unsurrendered Certificate with respect to the Parent Shares
represented thereby until the holder of record of such Certificate shall
surrender such Certificate in accordance with this Section. Subject to the
effect of applicable laws, following surrender of any such Certificate, there
shall be paid to the record holder of the Certificates representing whole
Parent Shares issued in exchange therefor, without interest, (i) at the
time of such surrender, the amount of dividends or other distributions, if any,
with a record date on or after the Effective Time which theretofore became
payable, but which were not paid by reason of the immediately preceding sentence,
with respect to such whole Parent Shares, and (ii) at the appropriate
payment date, the amount of dividends or other distributions with a record date
on or after the Effective Time but prior to surrender and a payment date
subsequent to surrender payable with respect to such whole Parent Shares.


 


(d)           No Further Ownership Rights in Company Common Stock or Preferred Stock.
All cash paid and Parent Shares issued upon the surrender for exchange of
Certificates in accordance with the terms hereof shall be deemed to have been
paid or issued, as the case may be, at the Effective Time in full satisfaction
of all rights pertaining to the shares of Company Common Stock, Preferred Stock
or Senior Preferred Stock, as the case may be, represented thereby. From and after
the Effective Time, the stock transfer books of the Company shall be closed and
there shall be no further registration of transfers on the stock transfer books
of the Surviving Corporation of the shares of Company Common Stock, Preferred
Stock or Senior Preferred Stock, as the case may be, which were outstanding
immediately prior to the Effective Time. If, after the Effective Time,
Certificates are presented to the Surviving Corporation for any reason, they
shall be canceled and exchanged as provided in this Section.


 


8

















 


(e)           No Fractional Shares. (i) No certificate or scrip representing
fractional Parent Shares will be issued in the Merger upon the surrender for
exchange of Certificates, and such fractional share interests will not entitle
the owner thereof to vote or to any rights of a stockholder of Parent.


 


(ii)           The total number of Parent Shares issued to each
holder of shares of Company Common Stock, Preferred Stock or Senior Preferred
Stock exchanged pursuant to the Merger shall be rounded down to the nearest
whole number of shares of Parent Shares. No consideration shall be paid to any
holder of capital stock of the Company with respect to any fraction of a share
of Parent Shares for which such holder would otherwise be entitled.


 


(f)            Termination of Exchange Fund. Any portion of the
Exchange Fund which remains undistributed to the holders of Company Common
Stock, Preferred Stock or Senior Preferred Stock for twelve months after the
Effective Time shall be delivered to Parent, upon demand, and any holders of
Company Common Stock, Preferred Stock or Senior Preferred Stock who have not
theretofore complied with this Article II shall thereafter look only to
Parent (subject to abandoned property, escheat and other similar laws) as
general creditors for payment of their claim for Parent Shares, cash and any
dividends or distributions with respect to Parent Shares. Parent shall be
liable to any holder of Company Common Stock, Preferred Stock or Senior
Preferred Stock, as the case may be, for Parent Shares (or dividends or
distributions with respect thereto) and cash delivered to a public official
pursuant to any applicable abandoned property, escheat or similar law.

shall be determined by multiplying ############# (or such portion thereof as is
to be paid in Parent Shares) by the Exchange Rate on the date of achievement of
the Second Milestone and dividing the product by the Thirty-Day Average Stock
Price. In the event of payment in Parent Shares, Parent shall make available to
the Representatives holding statements issued by the Parent’s share transfer
agent representing the number of duly and validly authorized whole Parent
Shares issuable in connection with the Second Milestone to be held for the
benefit of holders of Company Common Stock, Preferred Stock and Senior

cash. If the Parent pays the Fourth Milestone in whole or in part in Parent
Shares, the number of Parent Shares to be issued and delivered to the

(a)                                  Tax Returns. Parent shall prepare or cause to be prepared and file or cause to be filed,
in a manner consistent with the Company’s past practice (unless otherwise

28

















 


law), all Tax Returns for the Company (i) for
all Tax periods ending on or prior to the Closing Date which are filed after
the Closing Date and (ii) for all Tax periods beginning before and ending

on Tax Matters. The parties hereto and
the Surviving Corporation shall cooperate fully, as and to the extent
reasonably requested by another party, in connection with the filing of Tax
Returns pursuant to this Section and any audit, litigation or other
proceeding with respect to Taxes. Such cooperation shall include the retention
and (upon the other party’s request) the provision of records and information
which are reasonably relevant to any such audit, litigation or other proceeding
and making employees available on a mutually convenient basis to provide
additional information and explanation of any material provided hereunder. The

and records with respect to Tax matters pertinent to the Company relating to
any taxable period beginning before the Closing Date until the expiration of
the statute of limitations (and, to the extent notified by Parent, any
extensions thereof) of the respective taxable periods, and to abide by all
record retention agreements entered into with any taxing authority, (B) to
give the other party reasonable written notice prior to transferring,
destroying or discarding any such books and records and, if the other party so
requests, any party hereto or the Surviving Corporation, as the case may be,

request, to use their best efforts to obtain any certificate or other document
from any governmental authority or any other Person as may be necessary to
mitigate, reduce or eliminate any Tax that could be imposed (including, but not
limited to, with respect to the transactions contemplated hereby).


 


(c)                                  Certain
Taxes All transfer, documentary, sales,
use, stamp, registration and other substantially similar Taxes and fees
(including any penalties and interest) incurred in connection with this
Agreement (collectively, “Transfer Taxes”), shall be paid by the Company

Returns and other documentation with respect to all such Transfer Taxes and, if
required by applicable law, the Surviving Corporation and the Parent will, and
will cause their affiliates to, join in the execution of any such Tax Returns
and other documentation. The Representatives shall provide the Surviving

document(s) which may be required by any state taxing authority to relieve
the Parent of any obligation to withhold any portion of the payments made
pursuant to this Agreement.

Refunds. Any Tax refunds that are
received by Parent, the Surviving Corporation or any of their Subsidiaries, and
any amounts credited against Tax to which Parent, the Surviving Corporation or
any of their Subsidiaries become entitled, that relate to Tax periods or
portions thereof ending on or before the Closing Date shall be for the account
of the Company stockholders, and the Parent shall pay over to the
Representatives any such refund or the amount of any such credit within thirty
(30) days after receipt thereto. In addition, to the extent that a claim for
refund or a proceeding results in a payment or credit against Tax by a taxing
authority or other Government Authority to the Parent, Surviving Corporation or
any of their Subsidiaries


 


29

















 


of any amount that is both (i) accrued
on the Closing Date Balance Sheet and (ii) included in the calculation of
Net Liabilities, Parent shall pay such amount to the Representatives within
thirty (30) days after receipt thereto.


 


(e)                                  Tax Claims. If, subsequent to the Closing, any of Parent, the Surviving Corporation
or the Representative receives notice of a claim by any Governmental Authority,
that, if successful, might result in an indemnity payment hereunder (a “Tax
Claim”), then within fifteen (15) days after receipt of such notice, the
party receiving such notice shall give written notice of such Tax Claim to the
other parties. The Parent shall have the right to control the conduct and
resolution of any such Tax Claim; provided, however, that if the resolution of
any such Tax Claim (or any portion thereof) may affect the Taxes of the Company
for a Tax period ending on or prior to the Closing Date or a Tax period
beginning before and ending after the Closing Date, then the Representative and
Parent shall jointly control the conduct and resolution of such Tax Claim (or
portion thereof). If the Representative elects not to participate in the
conduct and resolution of any such Tax Claim, the Representative shall notify
Parent in writing and Parent shall have the right to control the conduct and
resolution of such Tax Claim; provided, however, that Parent shall keep the
Representative informed of all developments on a timely basis and Parent shall
not resolve such Tax Claim in a manner that could reasonably be expected to
have an adverse impact on the Indemnifying Party’s indemnification obligations
under this Agreement without the written consent of the Representative, which
shall not be unreasonably withheld. Each party shall bear its own costs
incurred in participating in any proceeding relating to any Tax Claim.


 


7.05.                        Regulatory and Other Approvals. Subject to the
terms and conditions of this Agreement and without limiting the provisions of
Sections 6.01, 6.02, 6.03 and 6.04, each of the Company and Parent will proceed
diligently and in good faith and will use all commercially reasonable efforts
to do, or cause to be done, all things necessary, proper or advisable to, as

the other party or such Governmental Authorities or other public or private
third parties may reasonably request.


 


7.06.                        Expenses. Except as set forth in Section 9.02,
whether or not the Merger is consummated, all costs and expenses incurred in
connection with this Agreement and the transactions contemplated hereby shall
be paid by the party incurring such cost or expense.


 


7.07.                        Notice and Cure. Each of Parent and the Company
will notify the other promptly in writing after obtaining knowledge of, and
contemporaneously will provide the other with true and complete copies of any
and all information or documents relating to, and will use all commercially
reasonable efforts to cure before the Closing, any event, transaction or
circumstance occurring after the date of this Agreement that causes or will
cause any covenant or agreement of Parent or the Company, as the case may be,
under this Agreement to be breached or that renders or will render untrue any
representation or warranty of Parent or the Company, as the case may be,
contained in this Agreement as if the same were made on or as of the date of
such event, transaction or circumstance. Each of Parent and the Company also
will notify the


 


30

















 


other promptly in writing of, and will use
all commercially reasonable efforts to cure, before the Closing, any violation
or breach of any representation, warranty, covenant or agreement made by Parent
or the Company, as the case may be, in this Agreement, whether occurring or
arising prior to, on or after the date of this Agreement. No notice given
pursuant to this Section shall have any effect on the representations,
warranties, covenants or agreements contained in this Agreement for purposes of
determining satisfaction of any condition contained herein. Notwithstanding the
foregoing provisions, the delivery of any notice pursuant to this paragraph
shall not constitute an acknowledgment or admission of a breach of this
Agreement.


 


7.08.                        Fulfillment of Conditions.  Subject to
the terms and conditions of this Agreement, each of Parent and the Company will
take or cause to be taken all commercially reasonable steps necessary or
desirable and proceed diligently and in good faith to satisfy each condition to
the other’s obligations contained in this Agreement and to consummate and make
effective the transactions contemplated by this Agreement, and except as
otherwise contemplated or permitted in this Agreement, neither Parent nor the
Company will, nor will it permit any of its Subsidiaries to, take or fail to
take any action that could be reasonably expected to result in the
non-fulfillment of any such condition.

11.01.                  Survival of Representations, Warranties, Covenants
and Agreements. The representations, warranties, covenants and agreements
contained in this Agreement shall survive for one year after the Closing Date, provided
that the representations and warranties made in Sections 3.04 shall survive for
two years after the Closing Date, the representations and warranties made in Section 3.15
shall survive for 90 days after the applicable statute of limitations and the
representation and warranty made in Section 3.11(d) shall survive for
the applicable statute of limitations for assertion of any employment claim
(the designated survival period for each representation and warranty, the “Survival
Period”); provided, however, that notwithstanding the foregoing, the
covenants and agreements of the Parent contained in Section 6.03 shall
survive for period coextensive with the term patent protection for the relevant
Specified Technology. Except for claims with respect to fraud solely against
the Person


 


41

















 


committing or alleged to have committed such
fraud, the right of each party hereto to assert indemnification claims and
receive indemnification payments pursuant to Section 11.02 shall be the
sole and exclusive right and remedy exercisable by such party with respect to
any breach by the other party hereto of any representation, warranty or
covenant in this Agreement, except that, in the event of any breach or
threatened breach by any party to this Agreement of any covenant or obligation
set forth in this Agreement for the benefit of any other party to this
Agreement, such other party shall be entitled to seek a decree or order of
specific performance or mandamus to enforce the observance and performance of
such covenant, obligation or other provision, and an injunction restraining
such breach or threatened breach.


 


11.02.                  Indemnification. (a) The Stockholders
severally and not jointly shall defend, indemnify and hold harmless the Parent
and its affiliates, officers, directors, agents and representatives (“Parent
Indemnitees”) and the Surviving Corporation from, against and in respect
of, and shall pay and reimburse the Parent Indemnitees and the Surviving
Corporation for, any and all claims, losses, costs, expenses, obligations,
liabilities, damages and recoveries, including, without limitation, reasonable
attorneys’ fees, whether or not arising from third party claims (collectively, “Losses”),
that Parent Indemnitees or the Surviving Corporation may incur, sustain or
suffer as a result of (i) subject to the expiration of the Survival
Period, any breach of or inaccuracy in any representation or warranty of the
Company contained in this Agreement or in the Disclosure Letter furnished by or
on behalf of the Company under this Agreement, or (ii) except to the
extent such Taxes are reflected in the reserve for Tax Liability (rather than
any reserve for deferred Taxes established to reflect timing differences
between book and Tax income) shown on the face of the Closing Date Balance
Sheet, Taxes of the Company or any of its Subsidiaries with respect to any
taxable year or portion thereof ending on or before the Closing Date, or (iii) any
breach of the covenants or agreements of the Company or the Company contained
in this Agreement (collectively, “Parent Losses”). No claim for recovery
of any Parent Losses under Section 11.02(a)(i) may be asserted by a
Parent Indemnitee or the Surviving Corporation after the expiration of the
applicable Survival Period; provided, however, that claims in
writing made by a Parent Indemnitee or the Surviving Corporation in good faith
and with reasonable specificity prior to the expiration of the applicable
Survival Period shall not thereafter be barred by the expiration of the
applicable Survival Period. For purposes of computing the amount of any Parent
Losses incurred by Parent: (A) there shall be deducted an amount equal to
the amount of any Tax benefit actually received or receivable by Parent or any
of its affiliates in connection with such Losses or any of the circumstances giving
rise thereto; and (B) there shall be deducted an amount equal to the
amount of any insurance proceeds, indemnification payments, contribution
payments or reimbursements actually received or receivable by Parent or any of
its affiliates in connection with such Losses or any of the circumstances
giving rise thereto. For purposes of calculating an amount described under Section 11.02(a)(ii),
in the case of any Taxes that are imposed on a periodic basis and are payable
for a Tax period that includes (but does not end on) the Closing Date, the
portion of such Tax which relates to the portion of such Tax period ending on
the Closing Date shall (x) in the case of any Taxes other than Taxes based
upon or related to income or receipts, be deemed to be the amount of such Tax
for the entire Tax period multiplied by a fraction the numerator of which is
the number of days in the Tax period ending on the Closing Date and the
denominator of which is the number of days in the entire Tax period, and (y) in
the case of any Tax based upon or related to income or receipts be deemed equal
to the amount which would be payable if the relevant Tax period ended on the
Closing Date. Any credits relating to a Tax period that begins


 


42

















 


before and ends after the Closing Date shall
be taken into account as though the relevant Tax period ended on the Closing
Date. All determinations necessary to give effect to the foregoing allocations
shall be made in a manner consistent with prior practice of the Company.


 


(b)                                 The Parent shall defend, indemnify and hold
harmless the Stockholders of the Company entitled to consideration pursuant to
this Agreement (the “Shareholder Indemnitees”) from, against and in
respect of any and all Losses that the Shareholder Indemnitees may incur,
sustain, or suffer as a result of (i) subject to the expiration of the
Survival Period, any breach of or inaccuracy in any representation or warranty
of the Parent contained in this Agreement or in the Parent Disclosure Letter
furnished by or on behalf of the Parent under this Agreement, (ii) any
breach of the covenants or agreements of the Parent contained in this Agreement
(collectively, the “Shareholder Losses”). No claim for recovery of any
Shareholder Losses under Section 11.02(b)(i) may be asserted by any
Shareholder Indemnitee after the expiration of the applicable Survival Period; provided,
however, that claims in writing made by the Shareholder Indemnitee in
good faith and with reasonable specificity prior to the expiration of the
applicable Survival Period shall not thereafter be barred by the expiration of
the applicable Survival Period.


 


(c)                                  Except with respect to any Parent Losses involving
proven fraud by the Company, the Stockholders shall not be liable to Parent
with respect to Parent Losses arising out of breaches of representations or
warranties unless and until, and then only to the extent that, the aggregate
amount of all Parent Losses shall exceed the sum of US$15,000 or equivalent
(the “Parent Basket”). The Company shall thereafter be liable for all
Parent Losses, whether or not in excess of the Parent Basket; provided, however,
that the Parent Indemnitees shall not be entitled to aggregate indemnification
under Section 11.02(a) in excess of the aggregate value of the
Holdback Shares; provided, further, however, the parties
to this Agreement agree that the Parent shall deduct from any consideration
owing pursuant to Section 2.01 (the Holdback Shares) prior to the issuance
or payment of such consideration, any indemnification amounts claimed under Section 11.02(a) and
that such deductions from the consideration owing pursuant to Section 2.01
(the Holdback Shares) shall be the sole and exclusive source of any
indemnification amounts payable to Parent pursuant to this Agreement and except
as provided in the first sentence hereof, no Stockholder of the Company shall
be personally liable for any indemnification except to the extent of having
such Stockholder’s consideration owing pursuant to this Agreement reduced by
such indemnification amounts.


 


(d)                                 Except with respect to any Shareholder Losses
involving proven fraud by the Parent, the Parent shall not be liable to the
Shareholder Indemnitees with respect to Shareholder Losses arising out of
breaches of representations and warranties unless or until, and then only to
the extent that, that aggregate amount of Shareholder Losses shall exceed the
sum of US$15,000 or equivalent (the “Shareholder Basket”). Parent shall
thereafter be liable for all Shareholder Losses whether or not in excess of the
Shareholder Basket; provided, however, that the Shareholder
Indemnitees shall not be entitled to aggregate indemnification under Section 11.02(b)(i) in
excess of US$300,000; provided, that such limitation shall not apply to any
Shareholder Losses that result because of Parent’s breach of the covenants and
agreements contained in Section 2.01, 2.02 or 6.03.


 


(e)                                  All claims for indemnification by the Parent
Indemnitees, the Surviving Corporation or the Shareholder Indemnitee (in such
capacity an “Indemnified Party”) against,


 


43

















 


respectively, the Stockholders or the Parent
(in such capacity, an “Indemnifying Party”) relating to a Third Party
Claim (as defined below) shall be asserted and resolved as set forth in this
Section:


 


(i)                                     In the event that any written claim or demand for
which an Indemnifying Party would be liable to an Indemnified Party is made
against or sought to be collected from any Indemnified Party by a third party, promptly
after the assertion of any such claim or demand (a “Third Party Claim”),
the Indemnified Party shall notify the Indemnifying Party of such Third Party
Claim; provided, however, that the failure promptly to give such
notice shall not affect any Indemnified Party’s rights hereunder except to the
extent that such failure shall adversely affect any Indemnifying Party or its
rights hereunder. The Indemnified Party shall advise the Indemnifying Party of
all facts relating to such assertion within the knowledge of the Indemnified
Party, and shall afford the Indemnifying Party the opportunity, at the
Indemnifying Party’s sole cost and expense, to participate in the defense
thereof and, if it so chooses, to assume the defense of such claims and to
settle or compromise any Third Party Claim; provided, that,
except with the prior written consent of the Indemnified Party, such consent
not to be unreasonably withheld, conditioned or delayed, no Indemnifying Party
in the defense of any such claim shall consent to entry of any judgment or
order, interim or otherwise, or enter into any settlement to the extent that it
provides for injunctive or other non-monetary relief against the Indemnified
Party. Should the Indemnifying Party so elect to assume the defense of such
Third Party Claim, the Indemnifying Party will not be liable to the Indemnified
Party for legal expenses incurred by the Indemnified Party in connection with
the defense thereof, except as specifically provided below. If the Indemnifying
Party assumes such defense, the Indemnified Party shall have the right to
participate in the defense thereof, it being understood that the Indemnifying
Party shall control such defense, and in any such action or proceeding. the
Indemnified Party shall have the right to retain its own counsel, but the fees
and expenses of such counsel shall be at its own expense unless (x) the
Indemnifying Party and the Indemnified Party mutually agree to the retention of
such counsel or (y) the named parties to any such suit, action or proceeding
(including any impleaded parties) include both the Indemnifying Party and the
Indemnified Party, and in the opinion of recognized outside counsel to the
Indemnified Party, representation of the Indemnifying Party and the Indemnified
Party by the same counsel would result in a conflict of interests between them.
Where the Shareholder Indemnitees are the Indemnifying or Indemnified Party
hereunder,, the Parent shall in any event be liable for the fees and expenses
of a single counsel for all such parties.


 


(ii)                                  The Indemnified Party shall not, without the prior
written consent of the Indemnifying Party, have the right to settle or
compromise any Third Party Claim subject to indemnification under this Section and
be indemnified therefor.


 


(iii)                               An Indemnifying Party shall not be liable under
this Section for any settlement effected without its prior written consent
of any Third Party Claim for which indemnity may be sought hereunder, which
consent shall not be unreasonably withheld. The Indemnifying Party may settle
any Third Party Claim without the consent of the Indemnified Party provided
that such settlement or release constitutes monetary damages


 


44

















 


only that are paid in full by the
Indemnifying Party. Each party shall cooperate in the defense or prosecution of
any Third Party Claim. Such cooperation shall include the retention and, upon
the request of the party defending such claim, the provision to such defending
party or records and information which are reasonably relevant to such claim
and making of employees available on a mutually convenient basis to provide
additional information and explanation of any matters relating to such claim.


 


Notwithstanding any other provision of this
Agreement, with respect to the obligation to indemnify for any Tax, (i) if
an Indemnified Party is requested to pay the Tax and sue for a refund, the
Indemnifying Party or Indemnifying Parties shall advance the full amount of the
Tax to the Indemnified Party on an interest free basis; (ii) no
Indemnifying Party shall be entitled to settle or to contest in court any claim
relating to Taxes if the settlement or an adverse court decision of the claim
would be likely, in the good faith judgment of the Indemnified Party, to cause
the Tax liability of the Indemnified Party or any affiliate to increase in any
taxable period ending after the Closing Date; and (iii) no proceedings may
be begun in any court unless the Indemnifying Party or Indemnifying Parties, if
requested by the Indemnified Party, provides a counsel’s opinion reasonably
satisfactory to the Indemnified Party that a reasonable basis exists to prevail
in those proceedings.


 


(f)                                    Any claim or demand relating to any matter for
which a party is entitled to indemnification hereunder shall be asserted by
written notice to the other party or parties from which indemnification is
sought, which notice shall specify in reasonable detail, insofar as such facts
are known to the party asserting such claim or demand, the facts and circumstances
giving rise to such claim on demand. Any amounts paid under this Article XI
will be treated as an adjustment to the aggregate consideration paid to the
holders of Company Common Stock, Preferred Stock and Senior Preferred Stock.


 


(g)                                 Notwithstanding anything in this Agreement to the
contrary, all amounts determined to be owing to Parent Indemnitees for
indemnification obligations of each of the Stockholders pursuant to this Section 11.02
shall be payable solely by offset from the Holdback Shares at the conclusion of
the procedures specified in this Section 11.02 (to the extent that the
same have not been released to the relevant Stockholder). In the event Parent
is entitled to offset against the Holdback Shares, the number of Holdback
Shares payable under Section 6.03, as the case may be, that shall be
canceled and no longer deliverable to each of the respective Stockholders shall
equal each such Stockholder’s proportional Share of Parent Losses divided by
the fair market value of the Holdback Shares with the fair market value of the
Holdback Shares being determined based on the Exchange Rate on the date of
set-off and application. On the six (6) month anniversary of the Closing
Date, Parent will transfer to the Stockholders entitled thereto (as informed by
the Representative), (i) fifty percent (50%) of the Holdback Shares (to
the extent remaining after the resolution of any claims with respect to Parent
Losses) minus (ii) the number of Holdback Shares equal to the aggregate
amount of claims by Parent pending on such date divided by the fair market
value of the Holdback Shares (determined using the Exchange Rate on the date of
determination). On the twelve (12) month anniversary of the Closing Date,
Parent will transfer to each of the Stockholders entitled thereto (as informed
by the Representative), (i) the remaining Holdback Shares of such
Stockholder (to the extent remaining after the resolution of any claims with
respect to Parent Losses and transfer pursuant to the prior sentence) minus (ii) the
number of Holdback Shares equal to the aggregate amount of claims by


 


45

















 


Parent pending on such date divided by the
fair market value of the Holdback Shares (determined based on the Exchange Rate
on the date of determination)). With respect to any pending claims referred to
in the preceding two sentences, promptly following resolution of any such
claims, the Holdback Shares, if any, which have not been offset by Parent in
connection with such resolution, and which would have been offset by Parent if
the claim had been resolved prior to the date set forth in the applicable
sentence of this Section 11.02(g), will be transferred to the Stockholders
ratably in accordance with the Ordinary Shares issuable to each Stockholder.

such releases and announcements as far in advance as practicable.


 


11.06.                  No Third Party Beneficiary. Except for the
provisions of Article 11, the terms and provisions of this Agreement are
intended solely for the benefit of each party hereto and their respective
successors or permitted assigns, and except as provided in Section 7.06 (which
is intended to be for the benefit of the persons entitled to therein, and may
be enforced by any of such persons), it is not the intention of the parties to
confer third-party beneficiary rights upon any other person.


 


11.07.                  No Assignment; Binding Effect. Neither this
Agreement nor any right, interest or obligation hereunder may be assigned by
any party hereto without the prior written consent of the other parties hereto
and any attempt to do so will be void. Subject to the preceding sentence, this Agreement
is binding upon, inures to the benefit of and is enforceable by the parties
hereto and their respective successors and assigns.


 


11.08.                  Headings. The headings used in this Agreement have
been inserted for convenience of reference only and do not define or limit the
provisions hereof.

Dollars” shall be deemed to be a reference to the legal currency of Australia.


 


47

















 


11.10.                  Invalid Provisions. If any provision of this
Agreement is held to be illegal, invalid or unenforceable under any present or
future law, and if the rights or obligations of any party hereto under this
Agreement will not be materially and adversely affected thereby, (i) such
provision will be fully severable, (ii) this Agreement will be construed
and enforced as if such illegal, invalid or unenforceable provision had never
comprised a part hereof, (iii) the remaining provisions of this Agreement
will remain in full force and effect and will not be affected by the legal,
invalid or unenforceable provision or by its severance herefrom and (iv) in
lieu of such illegal, invalid or unenforceable provision, there will be added
automatically as a part of this Agreement a legal, valid and enforceable
provision as similar in terms to such illegal, invalid or unenforceable
provision as may be possible.


 


11.11.                  Governing Law. (a) This Agreement shall be
governed by and construed in accordance with the laws of the State of Delaware
applicable to a contract executed and performed in such State without giving
effect to the conflicts of laws principles thereof. Each of the parties
irrevocably consents to the non-exclusive jurisdiction and venue of the state
and federal courts located within Santa Clara County, California and of
Queensland, Australia, in connection with any matter based upon or arising out
of this Agreement or the transactions contemplated hereby and agrees that
process may be served upon it in any manner authorized by the laws of the State
of California or Australia, as the case may be, for such persons and waives and
covenants not to assert or plead any objection which it might otherwise have to
such jurisdiction and such process.


 


(b)                            EACH OF THE PARTIES HERETO HEREBY WAIVES THE RIGHT
TO TRIAL BY JURY IN ANY PROCEEDING ARISING FROM THIS AGREEMENT OR THE

(c)                             Counterparts. This Agreement may be executed in any number of counterparts, each of
