SECTION .  Certain Covenants of Pledgor

Pledgor agrees that, so long as any of the Company’s obligations under the Notes
remain outstanding:

(a)

Pledgor shall ensure at all times that a Collateral Event of Default shall not
occur, and shall pledge additional Collateral in the manner described in
Sections 6(a) and 6(b) as necessary to cause such requirement to be met.

(b)

Pledgor shall, at the expense of Pledgor and in such manner and form as the
Collateral Agent may require, give, execute, deliver, file and record any
financing statement, notice, instrument, document, agreement or other papers
that may be necessary or desirable in order to create, preserve, perfect,
substantiate or validate any security interest granted (on a first priority
basis) pursuant hereto or to enable the Collateral Agent to exercise and enforce
its rights and the rights of the Secured Parties hereunder with respect to such
security interest.  To the extent permitted by applicable law, Pledgor hereby
authorizes the Collateral Agent to execute and file, in the name of Pledgor or
otherwise, UCC financing or continuation statements (which may be carbon,
photographic, photostatic or other reproductions of this Agreement or of a
financing statement relating to this Agreement) that the Collateral Agent in its
sole discretion may deem necessary or appropriate to further perfect, or
maintain the perfection of, the Security Interests.

(c)

Pledgor shall warrant and defend its title to the Collateral, subject to the
rights of the Collateral Agent and Secured Parties, against the claims and
demands of all persons.  The Collateral Agent and the Secured Parties (or, as
they may agree, one of them) may elect, but without an obligation to do so, to
discharge any Lien of any third party on any of the Collateral.

(d)

Pledgor agrees that it shall not change (1) its name or identity in any manner
or (2) its Location, unless in either case (A) it shall have given the
Collateral Agent not less than fifteen (15) days’ prior notice thereof and (B)
such change shall not cause any of the Security Interests to become unperfected
or subject any Collateral to any other Lien.

(e)

Pledgor agrees that so long as the Notes are outstanding it shall not (1) create
or permit to exist any Lien (other than the Security Interests) upon or with
respect to the Collateral, (2) sell or otherwise dispose of, or grant any option
with respect to, any of the Collateral or (3) enter into or consent to any
agreement pursuant to which any person other than the Pledgor, the Collateral
Agent, the Secured Parties and any securities intermediary through whom any of
the Collateral is held (but in the case of any such securities intermediary only
in respect of Collateral held through it) has or will have control (within the
meaning of Section 8-106 or 9-104 of the UCC) in respect of any Collateral.

(f)

Pledgor agrees to notify the Collateral Agent in writing immediately, and in any
event within two (2) Business Days following the acquisition by the Pledgor of
any additional shares of Common Stock after the date of this Agreement.

(g)

6

SECTION .  Administration of the Collateral and Delivery of Additional
Collateral.

(a)

Pledgor may pledge substitute Collateral hereunder at any time and shall pledge
additional Collateral if at any time additional Notes are issued pursuant to the
terms of the Note as set forth in Section 1(c) hereof or if the Pledgor acquires
any additional shares of Common Stock after the date of this Agreement.  If any
such additional Notes are issued, such Pledgor shall deliver additional
Collateral to the Collateral Agent no later than the closing date with respect
to the issuance of such additional Notes.  If any additional Collateral is
required to be delivered pursuant to Section 1(c) (other than as a result of the
issuance of additional Notes),Pledgor shall deliver such additional Collateral
to the Collateral Agent within five (5) Business Days of receipt by the Pledgor.
 Concurrently with the delivery of any additional or substitute Collateral,
Pledgor shall deliver to the Collateral Agent a certificate of Pledgor
substantially in the form of Exhibit A hereto and dated the date of such
delivery, (A) identifying the additional items of Collateral being pledged and
(B) certifying that with respect to such items of additional Collateral the
representations and warranties contained in Section 3 are true and correct with
respect to such Collateral and otherwise on and as of the date thereof.  In the
event of more than one Pledgor, the obligations of each Pledgor to deliver
additional Collateral hereunder shall be joint and several and the failure of
any Pledgor to pledge additional Collateral shall not discharge the obligation
of any other Pledgor.  If any substitute Collateral (rather than additional
Collateral) is pledged pursuant to this Section 6(a), the Collateral Agent shall
release a number of shares of Common Stock from the Security Interests created
hereunder equivalent to such substitute Collateral and return such shares of
Common Stock to the Pledgor.

(b)

Any delivery of Common Stock as Collateral to the Collateral Agent by Pledgor
shall be effected (A) in the case of Collateral consisting of certificated
Common Stock registered in the name of Pledgor, by delivery of certificates
representing such Common Stock to the Collateral Agent, accompanied by any
required transfer tax stamps, and indorsed and otherwise in suitable form for
transfer by delivery or accompanied by duly executed instruments of transfer or
assignment in blank, with signatures appropriately guaranteed, all in form and
substance satisfactory to the Collateral Agent, (B) in the case of Collateral
consisting of uncertificated Common Stock registered in the name of Pledgor, by
transmission by Pledgor of an instruction to the issuer of such Common Stock
instructing such issuer to reg ister such Common Stock in the name of the
Collateral Agent or its nominee, accompanied by any required transfer tax
stamps, and the issuer’s compliance with such instructions or (C) in the case of
Common Stock in respect of which security entitlements are held by Pledgor, by
the crediting of such Common Stock, accompanied by any required transfer tax
stamps, to a segregated account of the Collateral Agent.  Upon delivery of any
such Pledged Item under this Agreement, the Collateral Agent shall examine such
Pledged Item and any certificates delivered pursuant to Section 6(a) or
otherwise pursuant to the terms hereof in connection therewith to confirm that
they comply as to form with the requirements for Collateral.

(c)

If on any Business Day the Collateral Agent determines that a Collateral Event
of Default shall have occurred, the Collateral Agent shall promptly notify
Pledgor and Secured Parties of such determination by telephone call to Pledgor
and to each Secured Party followed by a written confirmation of such call.

(d)

7

(e)

In the event of an Event of Default, the Collateral Agent shall, upon request of
Secured Parties holding a majority of the aggregate principal amount of the
outstanding Notes, cause any or all of the Common Stock pledged hereunder
registered in the name of Pledgor or its nominee to be transferred of record
into the name of the Collateral Agent or its nominee.  Pledgor shall promptly
give to the Collateral Agent and Secured Parties copies of any notices or other
communications received by Pledgor with respect to Common Stock pledged
hereunder registered, or held through a securities intermediary, in the name of
Pledgor or its nominee and the Collateral Agent shall promptly give to Pledgor
and Secured Parties copies of any notices and communications received by the
Collateral Agent with respect to Common Stock pledged hereunder registered, or
held through a securities intermediary, in the name of the Collateral Agent or
its nominee.

(f)

Pledgor agrees that it shall forthwith upon demand pay to the Collateral Agent
or the Secured Parties, as the case may be:

(i)

amount of any taxes that the Collateral Agent or such Secured Party may have
been required to pay by reason of the Security Interests or to free any of the
Collateral from any Lien thereon, and

(ii)

the amount of any and all out-of-pocket expenses, including the fees and
disbursements of counsel and of any other experts, that the Collateral Agent or
such Secured Party may incur in connection with (A) the enforcement of this
Agreement or the Notes, including such expenses as are incurred to preserve the
value of the Collateral and the validity, perfection, rank and value of the
Security Interests, (B) the collection, sale or other disposition of any of the
Collateral, (C) the exercise by the Collateral Agent of any of the rights
conferred upon it hereunder or (D) any Event of Default.

Any such amount not paid on demand shall bear interest (computed on the basis of
a year of 360 days and payable for the actual number of days elapsed) at a rate
per annum equal to 5% plus the rate reported by Bloomberg Financial L.P. as the
prime rate.

SECTION .  Income and Voting Rights in Collateral

(a)

The Collateral Agent shall have the right to receive and retain as Collateral
hereunder, for the benefit of the Secured Parties, all proceeds of the
Collateral and Pledgor shall take all such action as the Collateral Agent shall
deem necessary or appropriate to give effect to such right.  All such proceeds,
including, without limitation, all dividends and other payments and
distributions that are received by Pledgor, shall be received in trust for the
benefit of the Collateral Agent and Secured Parties and, if the Collateral Agent
so directs shall be segregatedfrom other funds of Pledgor and shall, forthwith
upon demand by the Collateral Agent be paid over to the Collateral Agent as
Collateral in the same form as received (with any necessary endorsement).  

(b)

Unless an Event of Default shall have occurred and be continuing, Pledgor shall
have the right, from time to time, to vote and to give consents, ratifications
and waivers with respect to the Collateral, and the Collateral Agent shall, upon
receiving a written request from

8

Pledgor, accompanied by a certificate of the Company stating that no Event of
Default has occurred and is continuing, deliver to Pledgor, or as specified in
such request, such proxies, powers of attorney, consents, ratifications and
waivers in respect of any of the Collateral that is registered, or held through
a securities intermediary, in the name of the Collateral Agent or its nominee,
as shall be specified in such request, and shall be in form and substance
satisfactory to the Collateral Agent.

(c)

If an Event of Default shall have occurred and be continuing, the Collateral
Agent shall have the right, to the extent permitted by law, and Pledgor shall
take all such action as may be necessary or appropriate to give effect to such
right, to vote and to give consents, ratifications and waivers, and to take any
other action with respect to any or all of the Collateral with the same force
and effect as if the Collateral Agent were the absolute and sole owner thereof.

SECTION .  Remedies upon Events of Default

(a)

If any Event of Default shall have occurred and be continuing, the Collateral
Agent may exercise on behalf of the Secured Parties holding a majority of the
outstanding principal of the Notes (and shall so exercise at the direction of
such Secured Parties) all the rights of a secured party under the Uniform
Commercial Code (whether or not in effect in the jurisdiction where such rights
are exercised) and, in addition, without being required to give any notice,
except as herein provided or as may be required by mandatory provisions of law,
shall, at the direction of such Secured Parties, sell all of the Collateral, or
such lesser portion thereof as may be necessary to generate proceeds sufficient
to satisfy in full all of the obligations of the Company under the Notes or
hereunder, at public or private sale or at any broker’s board or on any
securities exchange, for cash, upon credit or for future delivery, and at such
price or prices as the Collateral Agent may deem commercially reasonable.
 Pledgor covenants and agrees that it will execute and deliver such documents
and take such other action as the Collateral Agent deems necessary or advisable
in order that any such sale may be made in compliance with law.  Upon any such
sale, the Collateral Agent shall have the right to deliver, assign and transfer
to the buyer thereof the Collateral so sold.  Each buyer at any such sale shall
acquire the Collateral so sold absolutely and free from any claim or right of
whatsoever kind, including any equity or right of redemption of Pledgor that may
be waived or any other right or claim of Pledgor.  The notice (if any) of such
sale required by Section 9-613 of the UCC shall (1) in case of a public sale,
state the time and place fixed for such sale, (2) in case of sale at a broker’s
board or on a securities exchange, state the board or exchange at which such
sale is to be made and the day on which the Collateral, or the portion thereof
so being sold, will first be offered for sale at such board or exchange, and (3)
in the case of a private sale, state the day after which such sale may be
consummated.  Any such public sale shall be held at such time or times within
ordinary business hours and at such place or places as the Collateral Agent may
fix in the notice of such sale.  At any such sale the Collateral may be sold in
one lot as an entirety or in separate parcels, as the Collateral Agent may
determine.  The Collateral Agent shall not be obligated to make any such sale
pursuant to any such notice.  The Collateral Agent may, without notice or
publication, adjourn any public or private sale or cause the same to be
adjourned from time to time by announcement at the time and place fixed for the
sale, and such sale may be made at any time or place to which the same may be so
adjourned.  In case of any sale of all or any part of the Collateral on credit
or for future delivery, the Collateral so sold may be retained by the Collateral
Agent until the selling price is paid by the buyer thereof, but the Collateral
Agent shall

9

not incur any liability in case of the failure of such buyer to take up and pay
for the Collateral so sold and, in case of any such failure, such Collateral may
again be sold upon like notice.  The Collateral Agent, instead of exercising the
power of sale herein conferred upon it, may proceed by a suit or suits at law or
in equity to foreclose the Security Interests and sell the Collateral, or any
portion thereof, under a judgment or decree of a court or courts of competent
jurisdiction.  The Collateral Agent or any other Secured Party or any of their
respective affiliates may be the purchaser, licensee, assignee or recipient of
the Collateral or any part thereof at any such sale and shall be entitled, for
the purpose of bidding and making settlement or payment of the purchase price
for all or any portion of the Collateral sold, assigned or licensed at such
sale, to use and apply any of the obligations secured hereunder owed to such
Person as a credit on account of the purchase price of the Collateral or any
part thereof payable by such Person at such sale.

The Pledgor recognizes that, by reason of certain prohibitions contained in the
Securities Act of 1933, as amended (the “Securities Act”), and applicable state
securities laws or other prohibitions contained in laws, rules and regulations
of governmental authorities, the Collateral Agent may be compelled, with respect
to any sale of all or any part of the Collateral, to limit purchasers to those
who will certify, among other things, that they are acquiring the Collateral for
their own account, for investment and not with a view to the distribution or
resale thereof or that otherwise satisfy the requirements of such governmental
authorities. The Pledgor acknowledges that any such private sales may be at
prices and on terms less favorable to the Collateral Agent that those obtainable
through a public sale without such restrictions (including, without limitation,
a public offering made pursuant to a registration statement under the Securities
Act), and, notwithstanding such circumstances, agrees that any private sale
shall be deemed to have been made in a commercially reasonable manner and that
the Collateral Agent shall have no obligation to engage in public sales and no
obligation to delay the sale of any Collateral for the period of time necessary
to permit the issuer thereof to register it for a form of public sale requiring
registration under the Securities Act or under applicable state securities laws,
even if the Pledgor or the issuer, as the case may be, would agree to do so.  If
the Collateral Agent determines to exercise its right to sell any or all of the
Collateral, upon written request, Pledgor shall from time to time furnish to the
Collateral Agent all such information as the Collateral Agent may request in
order to determine the number of securities included in the Collateral which may
be sold by the Collateral Agent as exempt transactions under the Securities Act
and the rules of the Securities and Exchange Commission thereunder, as the same
are from time to time in effect.

(b)

Pledgor hereby irrevocably appoints the Collateral Agent its true and lawful
attorney, with full power of substitution, in the name of Pledgor, the
Collateral Agent or any Secured Party or otherwise, for the sole use and benefit
of the Collateral Agent and the Secured Parties, but at the expense of Pledgor,
to the extent permitted by law, to exercise, at any time and from time to time
while an Event of Default has occurred and is continuing, all or any of the
following powers to be performed at the sole direction of the Secured Parties
holding a majority of the outstanding principal amount of the Notes with respect
to all or any of the Collateral:

(i)

to demand, sue for, collect, receive and give acquittance for any and all monies
due or to become due upon or by virtue thereof;

(ii)

10

(iii)

to settle, compromise, compound, prosecute or defend any action or proceeding
with respect thereto;

(iv)

to sell, transfer, assign or otherwise deal in or with the same or the proceeds
or avails thereof, as fully and effectually as if the Collateral Agent were the
absolute owner thereof (including, without limitation, the giving of
instructions and entitlement orders in respect thereof);

(v)

withdraw all moneys, instruments, securities and other property in any bank,
financial securities account, deposit or other account of the Pledgor
constituting Collateral for application to the obligations secured by this
Agreement;

(vi)

retain and apply any distributions on the Collateral to the obligations secured
by this Agreement; and

(vii)

exercise any and all rights as beneficial and legal owner of the Collateral,
including perfecting assignment of and exercising any and all voting, consensual
and other rights and powers with respect to the Collateral.

provided that the Collateral Agent shall give Pledgor at least ten (10) days’
prior written notice of the time and place of any sale or other intended
disposition of any of the Collateral, except any Collateral that threatens to
decline speedily in value, including, without limitation, equity securities, or
is of a type customarily sold on a recognized market.  The Collateral Agent and
Pledgor agree that such notice constitutes “reasonable notification” within the
meaning of Section 9-612 of the UCC.

(a)

Upon any delivery or sale of all or any part of any Collateral made either under
the power of delivery or sale given hereunder or under judgment or decree in any
judicial proceedings for foreclosure or otherwise for the enforcement of this

order of priorities:

first, to the payment to the Collateral Agent and any Secured Party of the
expenses of such sale or other realization, including compensation to the
Collateral Agent based upon the Collateral Agent’s hourly rates for its
professionals then in effect and such Secured Party and their respective agents
and counsel, and all expenses, liabilities and advances incurred or made by the
Collateral Agent or any Secured Party in connection therewith, including
brokerage fees in connection with the sale by the Collateral Agent or any
Secured Party of any Collateral;

second, to the payment to the Secured Parties, ratably, of all of the Company’s
obligations under the Note; and

finally, if all of the obligations of Pledgor hereunder and of the Company under
the Note have been fully discharged or sufficient funds have been set aside by
the Collateral Agent at the request of Pledgor for the discharge thereof, any
remaining proceeds shall be released to Pledgor.

SECTION .  The Collateral Agent

(a)

Each Secured Party hereby irrevocably appoints and authorizes the Collateral
Agent to take such action as agent on its behalf and to exercise such powers
under this Agreement as are delegated to the Collateral Agent by the terms
hereof, together with all such powers as are reasonably incidental thereto.

(b)

The obligations of the Collateral Agent hereunder are only those expressly set
forth in this Agreement.

(c)

The Collateral Agent may consult with legal counsel, independent public
accountants and other experts selected by it and shall not be liable for any
action taken or omitted to be taken by it in good faith in accordance with the
advice of such counsel, accountants or experts.

(d)

Neither the Collateral Agent nor any of its principals, directors, officers,
agents or employees shall be liable for any action taken or not taken by it in
connection with this Agreement (1) with the consent or at the request of any
Secured Parties holding a majority of the outstanding principal amount of the
Notes or (2) in the absence of its own willful misconduct, i.e. misappropriation
of the Collateral for its own benefit.  The Collateral Agent shall not incur any
liability by acting in reliance upon any notice, consent, certificate,
statement, or other writing(which may be a bank wire, telex or similar writing)
believed by it to be genuine or to be signed by the proper party or parties.

(e)

12

(f)

Pledgor shall indemnify the Collateral Agent against any cost, expense
(including counsel fees and disbursements), claim, demand, action, loss or
liability (except such as result from the Collateral Agent’s  willful
misconduct, i.e. misappropriation of the Collateral for its own benefit) that
the Collateral Agent may suffer or incur in connection with this Agreement or
any action taken or omitted by the Collateral Agent hereunder.

(g)

Beyond the exercise of reasonable care in the custody thereof, the Collateral
Agent shall have no duty as to any Collateral in its possession or control or in
the possession or control of any agent, bailee, clearing corporation or
securities intermediary or any income thereon or as to the preservation of
rights against prior parties or any other rights pertaining thereto.  The
Collateral Agent shall be deemed to have exercised reasonable care in the
custody and preservation of the Collateral if the Collateral is accorded
treatment substantially equal to that which it accords its own property, and
shall not be liable or responsible for any loss or damage to any of the
Collateral, or for any diminution in the value thereof, by reason of the act or
omission of any agent, bailee, clearing corporation or securities intermediary
selected by the Collateral Agent with diligent care in good faith (or selected
by an agent, bailee, clearing corporation or securities intermediary so selected
by the Collateral Agent or by any agent, bailee, clearing corporation or
securities intermediary selected in accordance with this parenthetical phrase).

(h)

Any corporation or association into which the Collateral Agent may be converted
or merged, or with which it may be consolidated, or to which it may sell or
transfer its agency business and assets as a whole or substantially as a whole,
or any corporation or association resulting from any such conversion, sale,
merger, consolidation or transfer to which it is a party, shall be and become a
successor Collateral Agent hereunder and vested with all of the title to the
Collateral and all of the powers, discretions, immunities, privileges and other
matters as was its predecessor without, except as provided above, the execution
or filing of any instrument or any further act, deed or conveyance on the part
of any of the parties hereto, anything herein to the contrary notwithstanding.

(i)

The Collateral Agent may be replaced and a successor Collateral Agent may be
appointed by the Pledgor and the Secured Parties holding a majority of the
outstanding principal amount of the Notes. If, however, there has been an Event
of Default, the Collateral Agent may be replaced and a successor Collateral
Agent may be appointed by the Secured Parties holding a majority of the
outstanding principal amount of the Notes.Upon the acceptance of any appointment
as the Collateral Agent by a successor Collateral Agent, that successor
Collateral Agent shall thereupon succeed to and become vested with all the
rights, powers, privileges and duties of the retiring Collateral Agent under
this Agreement, and the retiring Collateral Agent shall thereupon be discharged
from its duties and obligations under this Agreement. After any retiring
Collateral Agent’s resignation, the provisions hereof shall inure to its benefit
as to any actions taken or omitted to be taken by it under this Agreement while
it was the Collateral Agent.  The Collateral Agent’s responsibilities as
Collateral Agent hereunder shall terminate if the Collateral Agent shall resign
by giving ten (10) days’ written notice to the Company.  In the event of any
such resignation, the Pledgor and the Secured Parties holding a majority of the
outstanding principal amount of the Notes shall appoint a successor collateral
agent and the Collateral Agent shall deliver to such successor collateral agent
any Collateral held by the Collateral Agent.  If no successor collateral agent
is appointed by the end of the ten (10) day

13

notice period, the Collateral Agent’s sole responsibility shall be to safe-keep
the Collateral pending the appointment of a successor collateral agent.  In the
alternative, and at its own option, the Collateral Agent shall be entitled to
petition a court of competent jurisdiction to appoint a successor collateral
agent.

(j)

The Collateral Agent shall be compensated for its services in connection with
this Agreement as follows: (a) the Pledgor shall pay Collateral Agent a
non-refundable fee of $5,000 on the first closing of the Offering and (b) the
Pledgor shall pay Collateral Agent its regular hourly rates for any work
performed by the Collateral Agent as a result of a Collateral Event of Default
or an Event of Default including, but not limited to, any action taken by
Collateral Agent pursuant to Section 8 or 9 of this Agreement.  The Pledgor
shall pay the Collateral Agent promptly upon request but in no event later than
ten (10) days following the Collateral Agent’s delivery of an invoice to
Pledgor.

SECTION .  Miscellaneous.

(a)

This Agreement is not intended and shall not be construed to create any rights
in any person other than the Collateral Agent and the Secured Parties and their
respective successors and assigns and no other person shall assert any rights as
third party beneficiary hereunder.  Whenever any of the parties hereto is
referred to, such reference shall be deemed to include the successors and
assigns of such party.  All the covenants and agreements herein contained by or
on behalf of Pledgor and the Collateral Agent shall bind, and inure to the
benefit of, their respective successors and assigns whether so expressed or not,
and shall be enforceable by and inure to the benefit of the Secured Parties and
their respective successors and assigns.  Without limiting the generality of the
foregoing, any Secured Party may assign or otherwise transfer any indebtedness
held by it secured by this Agreement to any other Person, and such other Person
shall thereupon become vested with all the benefits in respect thereof granted
to such Secured Party, herein or otherwise. Neither the Pledgor nor the
Collateral Agent may assign its rights or obligations under this Agreement
without the prior written consent of Secured Parties holding a majority of the
aggregate principal amount of the outstanding Notes.

(b)

To the extent permitted by law, the unenforceability or invalidity of any
provision or provisions of this Agreement shall not render any other provision
or provisions herein contained unenforceable or invalid so long as this
Agreement as so modified continues to express, without material change, the
original intentions of the parties as to the subject matter of this Agreement
and the deletion of such portion of this Agreement will not substantially impair
the respective benefits or expectations of the parties hereto.

(c)

Any provision of this Agreement may be amended or waived if, and only if, such
amendment or waiver is in writing and signed, in the case of an amendment, by
Pledgor, the Collateral Agent and Secured Parties holding a majority of the
outstanding principal amount of the Notes or, in the case of a waiver, by the
party against whom the waiver is to be effective.  No failure or delay by either
party in exercising any right, power or privilege hereunder shall operate as a
waiver thereof nor shall any single or partial exercise thereof preclude any
other or further exercise thereof or the exercise of any other right, power or
privilege.  The rights and remedies herein provided shall be cumulative and not
exclusive of any rights or remedies provided by law.

at the time of such termination shall be fully released and discharged from the
Security Interests and delivered to Pledgor by the Collateral Agent, all at the
request and expense of Pledgor. Notwithstanding the foregoing, Pledgor agrees
that its obligations hereunder and the security interest created hereunder shall
continue to be effective or be reinstated, as applicable, if at any time
