WITNESSETH:
WHEREAS, MEMC Singapore is a wholly owned subsidiary of MEMC; and
WHEREAS, on (or as of) October 25, 2007, MEMC and Conergy entered into that

valuable consideration, the receipt and sufficiency of which are hereby

ARTICLE I
TERMINATION TRANSACTIONS

- 1 -
62075904_4

--------------------------------------------------------------------------------

1.1    Wafer Supply Contract Termination.
(a)    The Wafer Supply Contract shall be terminated, and the Wafer Supply
Contract shall cease to have any further force or effect, in each case
automatically (i) upon receipt by MEMC Singapore of payment of the Outstanding
Demand (as defined in Section 1.1(c) below); and (ii) upon receipt by MEMC
Singapore of the letter of credit pursuant to Section 1.1(d) hereof.  Upon the
occurrence of the events identified in (i) and (ii) of the foregoing sentence,
the termination of the Wafer Supply Contract shall have retroactive effect to
the date hereof.  MEMC Singapore and Conergy acknowledge that, except as
specified in Section 1.1(d) hereof, there are no outstanding purchase orders
under the Wafer Supply Contract.
(b)     MEMC Singapore currently holds a Refundable Capacity Reservation Deposit
in the amount of $21,300,000 (the “Existing RCRD”). Not later than noon, New
York City Time, on September 26, 2012, MEMC Singapore shall wire transfer an
amount equal to the Existing RCRD (without any setoff or deduction of any nature
whatsoever) to the Escrow Agent, to be held in escrow (pursuant to the Escrow
Agreement) pending, and to be released to Conergy upon, (i) if the Escrow Agent
is Commerzbank, New York Branch, the earlier of (x) receipt by Commerzbank, New
York Branch of a Fedwire tracking number or Fed reference number in respect of
the payment of the Outstanding Demand to MEMC Singapore (which, for the
avoidance of doubt, includes payment of the Outstanding Demand in accordance
with MEMC Singapore’s instructions), or (y) notice from MEMC or MEMC Singapore
to the effect that payment of the Outstanding Demand has been received, or (ii)
if the Escrow Agent is other than Commerzbank, New York Branch, the Escrow
Agent’s receipt of either (x) notice from Commerzbank, New York Branch to the
effect set forth in clause (i)(x), or (y) notice from MEMC or MEMC Singapore to
the effect that payment of the Outstanding Demand has been received (such
release to Conergy to be deemed to constitute the refund of the entire Existing
RCRD to Conergy).  The MEMC Parties, jointly and severally, covenant immediately
upon receipt of payment of the Outstanding Demand to notify the Escrow Agent
thereof. The Parties shall use their respective best efforts to retain the
Escrow Agent, and enter into the Escrow Agreement, as soon as possible after the
execution and delivery hereof (and, in any event, prior to noon, New York City
Time, on September 26, 2012).
(c)    Conergy has caused two letters of credit to be delivered to MEMC
Singapore by Commerzbank (or Commerzbank, New York Branch) pursuant to the Wafer
Supply Contract, one (number 150STB08300366) in the amount of $21,200,000 (the
“Original Letter of Credit”) and one (number 150STB12300168) in the amount of
$8,308,906.25 (the “New Letter of Credit”). Conergy acknowledges that the MEMC
Parties made a valid demand based on justified claims on the Original Letter of
Credit on September 17, 2012 (the “Outstanding Demand”) prior to its expiration
and that Commerzbank has acknowledged the validity of the Outstanding Demand and
will make payment in full thereunder to MEMC Singapore on September 27, 2012.
The MEMC Parties agree that the New Letter of Credit is hereby cancelled, with
immediate effect. MEMC Singapore shall deliver the executed originals of each of
the Original Letter of Credit and (to the extent the same was delivered to MEMC
Singapore or MEMC) the New Letter of Credit to Conergy or, at MEMC Singapore’s
option, directly to Commerzbank, New York Branch, without undue delay after the
execution and delivery hereof.

--------------------------------------------------------------------------------

MEMC Singapore represents and warrants to Conergy that neither of the MEMC
Parties has made any draw on the New Letter of Credit and covenants that neither
MEMC nor MEMC Singapore shall hereafter make any draw on the New Letter of
Credit. MEMC Singapore shall execute and deliver to Commerzbank, New York Branch
(with a copy to Conergy) a letter in the form of Annex A hereto by the close of
business in New York City on September 25, 2012. Without limitation of the
foregoing, MEMC Singapore forthwith shall execute and deliver to Commerzbank,
New York Branch such further instruments, and take such further actions, as
Commerzbank, New York Branch reasonably may request in order to effect or
evidence MEMC Singapore’s irrevocable consent to the cancellation of the New
Letter of Credit (including all rights to make any draw thereunder). Nothing in
this Agreement shall be read or construed to affect in any way the scheduled
payment to MEMC Singapore by Commerzbank of the Outstanding Demand on September
27, 2012.
(d)    As of the date hereof, the invoices (for product delivered by MEMC
Singapore to Conergy pursuant to the Wafer Supply Contract) listed in Annex B
hereto remain (disregarding the deduction/setoff notice in respect thereof dated
September 5, 2012 delivered by Conergy to MEMC Singapore, which notice MEMC
Singapore disputes and has not recognized) outstanding in the aggregate amount
of $5,499,564.00 (collectively, the “Outstanding Payables”). The Parties agree
that the Outstanding Payables shall become due on July 1, 2013 and shall carry
interest of 8% per annum calculated on a 360 days basis from the original due
dates thereof as set forth in Annex B. As security for the payment of the
Outstanding Payables when due, Conergy shall deliver to MEMC Singapore (by
delivery to its counsel, Bryan Cave, in Frankfurt, Germany) a new letter of
credit in the amount of $5,500,000 and in substantially the form of Annex C
hereto not later than the close of business in Frankfurt, Germany on September
25, 2012.
1.2    Transfer of Conergy’s Operations & Maintenance Business.
(a)    Conergy’s indirectly wholly owned German subsidiary Conergy Services GmbH
(“Conergy Services”) is currently a party to approximately 260 contracts with
third party customers under which Conergy Services is obliged against monetary
consideration to provide certain operations and maintenance services to such
customers (the “German O&M Customer Contracts”). The German O&M Customer
Contracts represent solar power plants in an aggregate output volume of
approximately 120MW. Conergy Services fulfills its duties under the German O&M
Customer Contracts either by itself or via third party subcontractors with which
Conergy Services has concluded subcontractor agreements (regarding field service
and maintenance tasks) for monetary consideration (the “German O&M Subcontractor
Contracts”) (the German O&M Customer Contracts together with the German O&M
Subcontractor Contracts together the “German O&M Contracts”).
(b)    In addition, Conergy’s indirectly wholly owned Italian subsidiary Conergy
Italia S.P.A. (“Conergy Italy”) is currently a party to approximately 30
contracts with third party customers under which Conergy Italy is obliged
against monetary consideration to provide certain operations and maintenance
services to such customers (the “Italian O&M Customer Contracts”). The Italian
O&M Customer Contracts represent solar power plants in an aggregate

--------------------------------------------------------------------------------

output volume of approximately 25MW. Conergy Italy fulfills its duties under the
Italian O&M Customer Contracts either by itself or via third party
subcontractors with which Conergy Italy has concluded subcontractor agreements
(regarding field service and maintenance tasks) for monetary consideration (the
“Italian O&M Subcontractor Contracts”) (the Italian O&M Customer Contracts
together with the Italian O&M Subcontractor Contracts together the “Italian O&M
Contracts”).
(c)    Finally, Conergy’s indirectly wholly owned Spanish subsidiary Conergy
Espana S.L.U. (“Conergy Spain”) is currently a party to approximately 10
contracts with third party customers under which Conergy Spain is obliged
against monetary consideration to provide certain operations and maintenance
services to such customers (the “Spanish O&M Customer Contracts”). The Spanish
O&M Customer Contracts represent solar power plants in an aggregate output
volume of approximately 30MW. Conergy Spain fulfills its duties under the
Spanish O&M Customer Contracts either by itself or via third party
subcontractors with which Conergy Spain has concluded subcontractor agreements
(regarding field service and maintenance tasks) for monetary consideration (the
“Spanish O&M Subcontractor Contracts”).
(Spanish O&M Customer Contracts together with the Spanish O&M Subcontractor
Contracts together the “Spanish O&M Contracts”).
(Conergy Services, Conergy Italy and Conergy Spain, each a “Conergy Company” and
together the “Conergy Companies”).
(German O&M Customer Contract, Italian O&M Customer Contracts and Spanish O&M
Customer Contracts together the “Conergy O&M Customer Contracts”).
(German O&M Subcontractor Contracts, Italian O&M Subcontractor Contracts and
Spanish O&M Subcontractor Contracts together the “Conergy O&M Subcontractor
Contracts”).
(German O&M Contracts, Italian O&M Contracts and Spanish O&M Contracts together
“Conergy O&M Contracts”).
(d)    The Parties have agreed that, as consideration to MEMC Singapore for the
termination of the Wafer Supply Contract, Conergy shall assign and transfer the
entire current Conergy O&M Contracts portfolio to MEMC subject to the following
terms and conditions:
(A)    Without undue delay and as far as legally and contractually permissible,
after the end of the Due Diligence Period (as defined in Section 1.2(d)(E)(ii)
below), and after MEMC has identified for the Conergy Parties the Conergy O&M
Contracts MEMC intends to assume (as described in Section 1.2(d)(E)(ii) below)
by providing to the Conergy Parties the list of Assumed Contracts that MEMC
determines to assume or reject (as described in Section 1.2(d)(E)(ii) below),
and subject in any event to Section 1.2(d)(E)(ii)(VI), Conergy shall cause the
Conergy Companies to assign and transfer each of such Assumed Contracts to MEMC
or an assignee denominated by MEMC (the “MEMC Assignee”). The Conergy Companies
and

--------------------------------------------------------------------------------

MEMC or the MEMC Assignee, respectively, shall enter or be caused to enter into
individual transfer agreements with respect to the individual Assumed Contracts
under applicable local laws without undue delay (the “O&M Contract Transfer
Agreements”) after receipt of the list of Assumed Contracts from MEMC. The O&M
Contract Transfer Agreements shall be governed by the laws of Germany, Italy or
Spain, respectively, and shall include only (x) language required for the
assignment of the Conergy O&M Contracts and (y) the terms expressly agreed in
this Section 1.2(d).
(B)    MEMC hereby undertakes towards Conergy that MEMC and/or the MEMC
Assignee, respectively, will assume the Assumed Contracts by way of assumption
of contract with effect as per the individual transfer date; it being understood
that Conergy and/or the respective Conergy Company remains fully liable for all
obligations prior to the individual transfer date, and the MEMC Parties assume
no liability for any actions or inactions by the Conergy Companies prior to such
date, including any obligation or liability for any breaches of contract or any
injury or damage caused by products manufactured or sold, or by services
rendered, by Conergy or the Conergy Companies prior to the individual transfer
date (including any obligations and liabilities under product warranties or
product liability for such products supplied prior to the individual transfer
date). Conergy accepts such undertaking on its own behalf and on behalf of the
Conergy Companies. On the other hand, MEMC shall take, and shall cause the MEMC
Assignees to take, such action (including turnover to the Conergy Companies of
payments received pursuant to the Assumed Contracts) as is necessary so that, as
between the Conergy Companies, on the one hand, and MEMC and the MEMC Assignees,
on the other hand, the Conergy Companies, as opposed to MEMC and the MEMC
Assignees, receive all payments and other benefits under the Assumed Contracts
attributable to work performed (including goods supplied or services provided)
prior to the relevant individual transfer dates.
(C)    The Parties, the Conergy Companies and the MEMC Assignee, respectively,
shall mutually use or caused to be used by the Parties reasonable best efforts
to obtain any consent of any third party legally or contractually required for
the transfer and assumption of any of the Assumed Contracts in accordance with
Sections 1.2(d)(A) and 1.2(d)(B) (provided that no Party shall be obligated to
offer any money or any other consideration to any such third party in order to
secure such consent (although a Party may unilaterally offer or pay money or any
other consideration to any such third party in order to secure such consent if
the Party chooses to do so)).
(D)    Only with respect to the Conergy Subcontractor Contracts constituting
Assumed Contracts:
(i)    If the consent of a third party to a transfer and assumption of a
particular Conergy Subcontractor Contract cannot be obtained pursuant to Section
1.2(d)(C), the relevant Conergy Company shall assign (and MEMC or the relevant
MEMC Assignee, as the case may be, shall accept such assignment), as far as
legally possible and contractually permitted (but only as far as legally
possible and contractually permitted), all claims, rights and obligations under
such Conergy Subcontractor Contract, and the respective Conergy Company and MEMC

--------------------------------------------------------------------------------

or the relevant MEMC Assignee, as the case may be, shall jointly notify such
third party of such assignment and assumption.
(ii)    Furthermore, if the consent of a third party to a transfer and
assumption of a particular Conergy Subcontractor Contract cannot be obtained
pursuant to Section 1.2(d)(C), the relevant Conergy Company party to such
Conergy Subcontractor Contract will, in respect of the external relationship,
remain the party to the relevant Conergy Subcontractor Contract for as long as
such third party consent cannot be obtained. The relevant Conergy Company and
MEMC or the relevant MEMC Assignee, as the case may be, respectively, for the
purposes of their internal relationship, shall behave and treat each other as if
consent had been obtained and the assumption and transfer had been effected. In
particular, the relevant Conergy Company shall continue to administer such
Conergy Subcontractor Contract and the rights and obligations related thereto
(in each case, as far as they have not been assigned to MEMC or the relevant
MEMC Assignee in accordance with Section 1.2(d)(D)(i)) in its own name but for
the account of MEMC or the relevant MEMC Assignee, in accordance with the
instructions of MEMC or the relevant MEMC Assignee. MEMC or the MEMC Assignee
shall indemnify and hold harmless the respective Conergy Company with regard to
any claims or any costs incurred as from the individual transfer date of a
Conergy Subcontractor Contract, if and to the extent the respective Conergy
Company does comply with the instructions of MEMC or the MEMC Assignee.
(iii)    If any arrangement pursuant to Section 1.2(d)(D)(ii) is not permitted
under the terms of any Conergy Subcontractor Contract, and/or the relevant third
party subcontractor does not grant its consent to the transfer and assumption of
the respective Conergy Subcontractor Contract within 6 months of the end of the
Due Diligence Period, the respective Conergy Company may terminate such Conergy
Subcontractor Contract in accordance with its terms at its own discretion, with
at least 10 Business Days advance notice to MEMC.
(iv)    For the avoidance of doubt, this Section 1.2(d)(D) above shall not apply
to any Conergy O&M Customer Contract constituting an Assumed Contract. If a
third party approval is required for the assignment and assumption of any such
Conergy O&M Customer Contract pursuant to this Section 1.2(d), such assignment
and assumption will not occur unless and until such third party approval has
been obtained. If such third party approval cannot be obtained within 6 months
of the end of the Due Diligence Period, the relevant Conergy O&M Customer
Contract shall not be assigned and assumed pursuant to this Section 1.2(d) but
shall instead remain with the respective Conergy Company for its own benefit for
good. This Section 1.2(d)(D)(iv) does not affect Section 1.2(d)(C).
(E)    Additional Terms with respect to the Assignment and Transfer of the
Conergy O&M Contracts; Due Diligence Period; Assumed Contracts.
(i)    The proposed assignment and transfer of the Conergy O&M Contracts set
forth herein shall expressly only include the Conergy O&M Contracts. For the
avoidance of doubt it shall expressly not include any employee, officer or
director, software infrastructure, IP rights and any monitoring systems engaged
or maintained by any of the Conergy Companies nor any shares in any Conergy
Company; provided however, that if a

--------------------------------------------------------------------------------

monitoring system has been installed in respect of any of the Conergy O&M
Contracts and if MEMC so requests, Conergy for a period of up to 12 months after
the date hereof agrees to continue to provide such monitoring services and
facilitate the migration of such monitoring services to MEMC or an MEMC Assignee
in respect of such Contract at the request of MEMC and upon the agreement of
MEMC to pay Conergy a reasonable fee for such monitoring system services, which
shall include reasonable cost of migration. In case that any of the employment
relationships with any employees of Conergy will be transferred to any MEMC
Party by statutory law, all obligations and liabilities relating to such
employees, including reasonable costs of termination of their employment, shall
exclusively be borne by Conergy and the Conergy Companies, unless MEMC elects to
take over such transferred employees. In case MEMC does not elect to take over
such employees, MEMC undertakes to terminate the respective employment
relationship by giving notice of termination with effect to the earliest
possible date. In case of litigation in court in respect of an employment
relationship so terminated, MEMC shall obtain Conergy’s prior written consent
before taking any legally binding and/or cost incurring measures, in particular
but not limited to procedural acts and agreements of any kind.
(ii)    
(I)    Subject to the remaining provisions of this Section 1.2(d)(E)(ii), the
proposed assignment and transfer of the Conergy O&M Contracts shall expressly
encompass the entire current list of Conergy O&M Contracts as of the date of
this Agreement. Subject to the remaining provisions of this Section
1.2(d)(E)(ii), Conergy shall not be entitled to withhold any current Conergy O&M
Contract from its obligation to assign and transfer all current Conergy O&M
Contracts to MEMC or the MEMC Assignee as set forth in this Section 1.2(d)
above. MEMC shall be entitled to review each of the Conergy O&M Contracts and
conduct appropriate and reasonable due diligence with respect to each of such
contracts over a period commencing on the date of this Agreement and continuing
for a period of ninety (90) calendar days after the date hereof (the “Due
Diligence Period”).
(II)    During the Due Diligence Period, as far as legally and contractually
permitted, Conergy agrees to make available to MEMC all reasonably requested
information in respect of the Conergy O&M Contracts, including information in
respect of historical performance under the Conergy O&M Contracts by all parties
to such contracts. MEMC will enter into a separate confidentiality agreement
with Conergy enabling MEMC to conduct such due diligence.
(III)    MEMC may, in accordance with (and only in accordance with) the
remaining provisions of this Section 1.2(d)(E)(ii), reject the assignment and
transfer of individual Conergy O&M Contracts, on a contract-by-contract basis,
in its sole discretion and shall not be deemed to have assumed any Conergy O&M
Contract so rejected. For those Conergy O&M Contracts that MEMC has not rejected
the assignment and transfer thereof in accordance with the remaining provisions
of this Section 1.2(d)(E)(ii), such contracts shall, subject to Section
1.2(d)(E)(ii)(VI) below, constitute an “Assumed Contract” under this Agreement.
For the avoidance of doubt, no Conergy O&M Contract other than Assumed Contracts
shall be assigned or transferred to MEMC or any MEMC Assigned pursuant to this
Section 1.2(d).

--------------------------------------------------------------------------------

(IV)    Not later than the 60th calendar day of the Due Diligence Period, MEMC
shall provide Conergy with a tentative list of the Conergy O&M Contracts (if
any) that MEMC elects to reject. If MEMC does not so elect tentatively to reject
any of the Conergy O&M Contracts prior to or on such 60th calendar day, then the
Due Diligence Period shall be deemed to have ended on such 60th calendar day and
no Conergy O&M Contracts shall be rejected.
(V)    If, not later than such 60th calendar day, MEMC so delivers a tentative
list of rejected Conergy O&M Contracts, then Conergy shall have the right to
accept MEMC’s tentative list of rejected Conergy O&M Contracts or to deliver to
MEMC, not later than the 75th calendar day of the Due Diligence Period, a
modified list of rejected Conergy O&M Contracts. Conergy’s modified list may
delete Conergy O&M Contracts that were on MEMC’s tentative list of rejected
Conergy O&M Contracts. If Conergy fails so to timely deliver such a modified
list to MEMC, Conergy shall be deemed to have accepted MEMC’s tentative list. If
Conergy accepts, or is deemed to have accepted, MEMC’s tentative list of
rejected Conergy O&M Contracts, then MEMC’s tentative list of rejected Conergy
O&M Contracts shall become final and the Due Diligence Period shall be deemed to
have ended on the date of such acceptance or deemed acceptance, as the case may
be.
(VI)    If, not later than such 75th calendar day, Conergy delivers a modified
list of rejected Conergy O&M Contracts to MEMC, then the Parties shall spend at
least the next 14 calendar days negotiating in good faith the modified list of
rejected Conergy O&M Contracts in order to try to come to an agreement on the
list. At the end of that negotiation period (should it occur), MEMC shall have
the right, by notice to such effect to Conergy delivered prior to the last day
of the Due Diligence Period, to: (i) accept Conergy’s modified list, after such
negotiation period, in which case such modified list (as negotiated) shall be
the final list of rejected Conergy O&M Contracts for all purposes of this
Section 1.2(d), (ii) elect that there shall be no rejected Conergy O&M
Contracts, in which case there shall be no such rejected Conergy O&M Contracts,
or (iii) elect to receive a $3,000,000 cash payment (the “O&M Cash Payment”). If
MEMC fails to timely make one of such elections, then MEMC shall be deemed to
have accepted Conergy’s modified list (as may have been further negotiated). If
MEMC elects the O&M Cash Payment, then, any term of this Section 1.2(d) to the
contrary notwithstanding, (x) none of the Conergy O&M Contracts shall constitute
an “Assumed Contract” (and no such Conergy O&M Contract shall be assigned and
transferred to MEMC or any MEMC Assignee) and (y) Conergy instead shall pay MEMC
Singapore the O&M Cash Payment in three equal installments, each such
installment being due and payable on the last business day of June, September
and December of 2013. As security for the payment of the O&M Cash Payment when
due (if applicable), Conergy shall deliver to MEMC (by delivery to its counsel,
Bryan Cave, in New York City) a letter of credit (drawn on Commerzbank, New York
Branch, or such other New York bank reasonably acceptable to MEMC) for the O&M
Cash Payment no later than noon, New York City Time, on September 26, 2012 (the
“O&M Letter of Credit”). Upon payment by Conergy of each installment of the O&M
Cash Payment, MEMC shall cooperate with Conergy in ensuring that a respective
reduction of the O&M Letter of Credit is actually effected and to make any
declarations, in particular vis-à-vis the bank issuing the O&M Letter of

--------------------------------------------------------------------------------

Credit, necessary or useful for ensuring such reduction of the amount of the O&M
Letter of Credit.
(VII)    The Parties acknowledge that it is their mutual intent to keep the
number of rejected Conergy O&M Contracts to the lowest amounts mutually
commercially reasonable. Without limitation of the foregoing, MEMC acknowledges
that it is being given the right to reject the assignment and transfer of
individual Conergy O&M Contracts not to enable MEMC to “cherry-pick” the most
attractive of the Conergy O&M Contracts, but rather to avoid MEMC having to
assume individual Conergy O&M Contracts that, for reasons other than the basic
economics thereof, would be unreasonable, impractical or unduly burdensome for
MEMC to assume, and MEMC shall exercise its right to reject the assignment and
transfer of individual Conergy O&M Contracts in a manner that is consistent with
the foregoing. Conversely, Conergy shall have the right to submit modified list
of rejected Conergy O&M Contracts only if Conergy concludes, in good faith and
having earnestly considered adjustments to its business plan that might permit
Conergy to avoid such a burdensome effect, that it would be burdensome to
Conergy (to a non-de minimus extent) to continue to have to perform the Conergy
O&M Contracts specified in MEMC’s tentative list of rejected Conergy O&M
Contracts if the other Conergy O&M Contracts are transferred to MEMC (or one or
more MEMC Assignees). For the avoidance of doubt, MEMC’s tentative list of
rejected Conergy O&M Contracts may take the form of a list of specific Conergy
O&M Contracts that MEMC elects to have transferred to it, in which case MEMC
shall be deemed to have designated each other Conergy O&M Contract in effect on
the date hereof as a rejected Conergy O&M Contract.
(iii)    The assignment and transfer of the Conergy O&M Contracts shall
expressly only encompass the entire current Conergy O&M Contracts, i.e., the
Conergy O&M Contracts that are in force at the date hereof. Any other future O&M
contract of any company within the Conergy group after the date of this
Agreement shall not be affected by this Agreement, nor shall any Conergy group
company be restricted in any way to engage in any O&M business in any country in
the future; provided, however, that as to the specific solar power plants
represented by the Conergy O&M Contracts transferred hereunder, Conergy agrees
to not solicit future O&M business as to those specific solar power plants only
for a period of three (3) years after the date of this Agreement.
