 WACKER    POLYSILICON 
 Appendix B 
 General Conditions of Sale 
  

	1.	Generally: 

  

	    	All our supplies and services as well as all contracts concluded with us are exclusively subject to the following conditions of sale. Terms of the Purchaser which contradict or
which deviate from our sales terms and which are not expressly recognised by us are not valid even if we do not expressly object to them. Where a continuing business relationship exists, all future contracts, supplies and services are also subject
to our conditions of sale. 

  

	2.	Offer, Conclusion of Contract: 

  

	    	Our offers are subject to change and non-binding. Orders are only valid if confirmed by us in writing or if recognised by us through the act of delivery. Any additional verbal
agreements, supplements and modifications are also only valid if confirmed in writing. 

  

	3.	Delivery, Default: 

  

	3.1	Unless otherwise agreed, any dates quoted for delivery are non-binding. 

  

	3.2	We are entitled to make partial deliveries as far as the Purchaser must reasonably accept this in the circumstances of an individual case. The corresponding invoices issued are
payable without regard to whether complete delivery has been made. 

  

	3.3	In the event delivery is delayed, the Purchaser may set us a reasonable grace period with the notice that he rejects the acceptance of the delivery item after expiry of the grace
period. After the expiry of the grace period, the Purchaser is entitled to cancel the contract of sale through written notice or to request damages instead of performance. 

  

	    	At our request the Purchaser is obligated to state within a reasonable period whether he cancels the contract due to delay in delivery, seeks damages instead of performance or
insists on performance. 

  

	3.4	Our liability is set forth in para. 9. Furthermore in the event of slight negligence, our liability is limited to the invoice value of the respective delivery item.

  

	4.	Return of loan packaging: 

  

	    	In the event of delayed return (meaning in the event normal unloading times are exceeded) of loading equipment, loading tanks and other loan packaging we reserve the right to charge
the Purchaser for the costs incurred by us. 

  

	5.	Prices: 

  

	5.1	Unless otherwise expressly agreed, prices are quoted “ex works” excluding packaging and plus delivery and shipping costs as well as plus any applicable Value Added Tax.

  

	5.2	The prices valid on the day of dispatch shall apply. Should the latter be higher than the contractual price, the Purchaser is entitled to cancel the contract with regard to the
quantities still to be delivered. Cancellation shall be made within 14 days after notification of said price increase. 

  

	6.	Payment: 

  

	6.1	The payment shall be made in Euro to one of our bank accounts indicated on the reverse side. 

  

	6.2	Should Purchaser be in arrears with payment, interest for default shall be due and payable at 12%, but at least 8% above the respective base interest rate. We reserve the right to
claim further damages. If the interest we claim is higher than the statutory interest for delayed payment, the Purchaser has the right to demonstrate lower damages just as we have the right to show that greater damages were incurred.

  

	6.3	Should Purchaser be in arrears with payment or should there be reasonable doubts as to Purchaser’s solvency or credit rating, we are – without prejudice to our other
rights – entitled to require payment in advance for deliveries not yet made, and to require immediate payment of all our claims arising from the business relation. 

  

	6.4	Bills of exchange and cheques shall be accepted upon separate agreement and only by way of payment. All expenses incurred in this regard shall be borne by the Purchaser.

  

	6.5	Only uncontested or legally proved claims shall entitle the Purchaser to set-off or withhold payment. 

  

	7.	Force Majeure: 

  

	    	Events of Force Majeure, in particular strikes, lock outs, operation or transport interruptions, including at our suppliers, shall suspend the contractual obligations of each party
for the period of the disturbance and to the extent of its effects. Should the delays caused exceed a period of 6 weeks, both parties shall be entitled to cancel the contract, with respect to the contractual performance affected by such delays. No
other claims exist. 

  

	8.	Quality: 

  

	8.1	All our data, especially data relating to product suitability, processing and use, as well as to technical support have been compiled to the best of our knowledge. The Purchaser,
however, must still perform his own inspections and preliminary trials. 

  

	8.2	The Purchaser undertakes to examine the goods immediately after delivery with respect to any defects concerning quality and suitability of purpose and object to ascertainable
defects. Sample testing shall also be performed if this can be reasonably expected of the Purchaser. Failure to proceed in aforesaid manner shall result in the goods being regarded as accepted. 

  

	8.3	Complaints must be made within 8 days after receipt of the goods. In case of hidden faults, however complaints are to be made immediately on discovery, within one year after receipt
at the very latest. Said claims shall only be taken into consideration if and when made in writing and with the relevant documentation attached. To comply with the time limit it shall be sufficient if the complaint is sent in good time.

  

	8.4	We are not liable on the basis of public statements by us, the manufacturer or his agents, if we were not aware of the statement or were not required to have knowledge thereof, the
statement was already corrected at the time of the purchase decision or the Purchaser cannot show that the statement influenced his purchase decision. 

  

	8.5	We are not liable for defects which only marginally reduce the value or the suitability of the object. A marginal defect exists in particular if the defect can be removed by the
Purchaser himself with insignificant effort. 

  

	8.6	If the Purchaser requests replacement performance due to a defect we may choose whether we remove the defect ourselves or deliver a defect-free object as a replacement. The right to
reduce the price or cancel the contract in the event of unsuccessful replacement performance shall remain unaffected. 

  

	8.7	Where complaints are justified, the goods may only be returned to us at our expense if after we receive notice of the defect we do not offer to collect or dispose of the goods.

  

	8.8	If increased costs arise because the Purchaser has transferred the goods to a place other than his commercial place of business, we shall charge the Purchaser for the increased
costs in connection with the remedying of the defect, unless the transfer corresponds to the designated use of the object. 

  

	8.9	Damage and claims for reimbursement of expenses shall remain unaffected as far as not excluded by para. 9. 

  

	8.10	All claims due to a defect are subject to a limitation period of one year after delivery of the object. No warranty is made for used objects. The statutory limitation period for
objects which are used for a building structure in accordance with their usual manner of use, and which cause the defectiveness thereof, shall remain unaffected. 

  

	8.11	The rights of the Purchaser under §§ 478. 479 German Civil Code remain unaffected. 

  

	9.	Liability: 

  

	    	Our liability is excluded regardless of the legal grounds. 

  

	    	This shall not apply in the event of intentional actions or gross negligence by us or our legal representatives or agents or in the event of breach of material contractual duties.

  

	    	In the event of a slightly negligent breach of material contractual duties, our liability is limited to twice the invoice value of the respective delivery item. For damages due to
delayed performance para. 3.4 shall also apply. Our liability for damages due to injury to life, the body or health, the liability based on a guarantee and under mandatory statutory provisions, in particular the Product Liability Act, remain
unaffected. 

  

	10.	Reservation of Ownership: 

  

	10.1	The goods that have been sold remain our sole property until all outstanding debts arising from the business connection with the Purchaser have been paid in full. The Purchaser has
power of disposal of the purchased goods in the ordinary course of business, or he may process the goods until revocation by us. 

  

	10.2	Reservation of ownership and power of disposal, as laid down in clause 10.1, also apply to the full value of the manufactured goods produced by processing, mixing and blending or
combining our goods. In each case we qualify as the manufacturer. In cases where the goods are processed, mixed and blended or combined with those of a third party, and where the reservation of the latter continues to apply, then we acquire joint
ownership in proportion to the invoice value of those processed goods. If security rights of a third party are in fact or in low below that share, the difference will be to our benefit. 

  

	10.3	If the Purchaser resells our goods to third parties he hereby assigns the entire resulting payment claim – or in the amount of our joint share therein (see para. 10.2) –
to us. In the event the parties agree on a current account, the respective balance amounts shall be assigned. However, the Purchaser shall be entitled to collect such payment claim on our behalf until we revoke such right or until his payments are
discontinued. The Purchaser is only authorized to make assignment of these claims – even only for the purpose of collection by way or factoring – with our express written consent. 

  

	10.4	The Purchaser shall immediately give notice to us if any third party raises any claim with respect to such goods or claims which are owned by us. 

  

	10.5	If the value of the collateral exceeds our accounts receivable by more than 20% then we will release collateral on demand and at our discretion. 

  

	10.6	We are also entitled to take back goods on the basis of the reservation of title, even if we have not previously cancelled the contract. If products are taken back by way of the
exercise of the reservation of ownership, this shall not constitute cancellation of the contract. 

  

	10.7	If the laws of the country in which the goods are located after delivery do not permit the Vendor to retain the title to said goods, but allow the retention of other similar rights
to the delivery item, the Purchaser shall provide us with such other equivalent right. The Purchaser undertakes to assist us in the fulfillment of any form requirements necessary for such purpose. 

  

	11.	Place of Fulfilment, Applicable Law and Jurisdiction: 

  

	11.1	The originating point of the goods shall, in each case, be the place of fulfilment for the delivery. Munich shall be the place of fulfilment for payment. 

 

	11.2	Exclusively the laws of the Federal Republic of Germany shall apply between the parties. The application of the 1980 United Nations Convention on Contracts for the International
Sale of Goods is expressly excluded. 

  

	11.3	If the Purchaser is a merchant or does not have a general place of jurisdiction in Germany, the place of jurisdiction is Munich. We shall, however, have the right to also bring a
claim against the Purchaser at his general place of jurisdiction.

 Exhibit 10.1 
 SETTLEMENT AGREEMENT 
 This Settlement Agreement (“Settlement Agreement”) is made this 22nd
day of August 2006 (the “Effective Date”) by and among Consolidated Container Holdings LLC (“CCH”), a limited liability company organized and existing under the laws of the State of Delaware, Consolidated Container Company LP
(“CCC”), a limited partnership organized and existing under the laws of the State of Delaware, and Dean Foods Company (“Dean Foods”), a corporation organized and existing under the laws of the State of Delaware. 
 BACKGROUND 
 1. 1999 Agreements. As of
July 2, 1999, CCH and Suiza Foods Corporation (“Suiza”), now known as Dean Foods, entered into a Supply Agreement for PET Bottles (the “PET Agreement”), a Supply Agreement for HDPE Bottles (the “HDPE Agreement”)
and a Supply Agreement for Bottle Components (collectively, the “1999 Supply Agreements”) pursuant to which Suiza and CCH agreed, among other things, for CCH to provide PET and HDPE bottles and bottle components to Suiza. In connection
with the 1999 Supply Agreements, on July 1, 1999, CCH and Suiza entered into three letter agreements (the “Letter Agreements”) which addressed, among other things, (a) Suiza’s purchase of caps from CCH, (b) Suiza’s
right to audit the books and records of CCH and (c) competitive pricing under the 1999 Supply Agreements. The Letter Agreements and the 1999 Supply Agreements are collectively referred to herein as the “1999 Agreements.” 

2. Subsequent Agreements/Amendments. As of June 25, 2004, CCC, as successor in interest by assignment from CCH, and Dean Foods entered
into the Amended and Restated Supply Agreement for Bottle Components, amended as of July 1, 2006 (the “2004 Bottle Components Agreement”) pursuant to which the parties agreed, among other things, for CCC to provide bottle components
to Dean Foods. The 2004 Bottle Components Agreement superseded the 1999 Supply Agreement for Bottle Components. 
 3. Resolution of
Disputes. Recently, CCH and CCC notified Dean Foods that CCH, CCC or their Affiliates (defined herein) may have charged Suiza, Dean Foods and/or their Affiliates prices in excess of those permitted under the above-mentioned agreements. CCH, CCC
and Dean Foods have agreed to resolve and to compromise, on a permanent and final basis, all such issues and other issues that may exist between the parties, as set forth in this Settlement Agreement. 
 TERMS 
 NOW, THEREFORE, for and in
consideration of the mutual promises set forth below, and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, CCH, CCC and Dean Foods hereby agree as follows: 
 1. Payment and Guarantee. CCC hereby promises to pay ten million dollars ($10,000,000 USD) (the “Settlement Amount”), without interest,
to Dean Foods in accordance with the following schedule: four million dollars ($4,000,000 USD) on or before the Initial 
  

 - 1 - 

 Payment Date (defined below); three million dollars ($3,000,000 USD) on or before the one-year anniversary of the
Effective Date hereof, and three million dollars ($3,000,000 USD) on or before the two-year anniversary of the Effective Date hereof. If a Change of Control (defined herein) occurs before CCC has paid the Settlement Amount in full, the outstanding
balance shall be due and payable on or before the effective date of the Change of Control. For purposes hereof, a “Change of Control” shall mean the first to occur of the following events: (a) Vestar Packaging LLC and its affiliates
cease to be the “beneficial owner” (as defined in Rules 13d-3 and 13d-5 under the Securities Exchange Act of 1934, as amended), directly or indirectly, of a majority in the aggregate of the total voting power of the CCH membership units as
a result of a sale or transfer of CCH membership units in consideration for cash or marketable securities; or (b) the sale of all or substantially all of the assets of CCH. The “Initial Payment Date” shall be September 30, 2006,
unless CCC and CCH do not have at least $40 million in available funds, including without limitation cash, marketable securities, and funds available under existing credit facilities, as of such date; if CCC and CCH do not have $40 million in
available funds as of September 30, 2006, then the Initial Payment Date shall be October 31, 2006 unless CCC and CCH do not have at least $40 million in available funds as of such date; if CCC and CCH do not have $40 million in available
funds as of October 31, 2006, then the Initial Payment Date shall be November 30, 2006 unless CCC and CCH do not have at least $40 million in available funds as of such date; if CCC and CCH do not have $40 million in available funds as of
November 30, 2006, then the Initial Payment Date shall be December 31,2006. Notwithstanding anything herein, the Initial Payment Date shall in no event be later than December 31, 2006. CCH hereby guarantees payment of the Settlement
Amount to Dean Foods. 
 2. Mutual Waiver and Release 
 (a) CCH, its Affiliates including, without limitation, CCC, and each of their members, managers, shareholders, employees, agents, officers and directors (collectively, the “CCH Related Parties”) hereby
release and forever discharge all claims, charges, complaints, demands, debts, dues, sums of money, accounts, costs, controversies, liens, damages and causes of action of every kind and nature, whether known or unknown, actual or contingent, either
at law or in equity (collectively, “Claims”), that they had or may have had as of June 30, 2006, against Dean Foods, its Affiliates and each of their members, managers, shareholders, employees, agents, officers and directors (the
“Dean Related Parties”) arising from any breaches, omissions, obligations, liabilities, and damages arising under or relating to the 1999 Agreements or the 2004 Bottle Components Agreement, expressly excluding from such release and
discharge any and all Claims of CCH, its Affiliates and each of the CCH Related Parties for breach of this Settlement Agreement. The term “Affiliates” shall have the meaning assigned to the term in the 1999 Agreements. 
 (b) Dean Foods, its Affiliates and each of the Dean Related Parties hereby release and forever discharge all Claims they had or may have had as of
June 30, 2006, against CCH, its Affiliates and CCH Related Parties arising from any breaches, omissions, obligations, liabilities and damages arising under or relating to the 1999 Agreements or the 2004 Bottle Components Agreement, expressly
excluding from such release and discharge any and all Claims of Dean Foods, its Affiliates and each of the Dean Related Parties for breach of this Settlement Agreement including, without limitation, a breach of the respective obligations of CCC and
CCH for payment and for guarantee of payment of the Settlement Amount. 
  

 - 2 - 

 (c) The releases hereunder shall not constitute a release of any breaches or non-compliance by either
party or their respective Affiliates that arise under the 2004 Bottle Components Agreement on or after July 1, 2006. Any breach or non-compliance under the 2004 Bottle Components Agreement by either party or their respective Affiliates on or
after July 1, 2006, shall be deemed to constitute a new breach and/or default under the 2004 Bottle Components Agreement. Any such new breach and/or default will be subject to the terms, provisions and conditions of the 2004 Bottle Components
Agreement, including the remedies provided for in such agreement and those remedies otherwise available under applicable law, and any liabilities and/or damages relating to breaches of the 2004 Bottle Components Agreement will be limited to
liabilities and/or damages sustained or incurred after July 1, 2006 (e.g., if a party has breached a performance obligation from June 3, 2004 through July 1, 2006, and that breach continues following July 1, 2006, the other party
would have the right to seek only those damages sustained by it following July 1, 2006). 
 (d) It is understood and agreed by the
parties that this Settlement Agreement is a compromise of disputed claims. This Settlement Agreement does not constitute and shall not be construed or interpreted to constitute an admission of liability by any party hereto, which liability is
expressly denied by each party against whom liability is or may be asserted. 
 3. Effect on Other Agreements. As of July 1,
2006, the parties agree that (a) except as to the specific waivers and releases set forth above, the 2004 Bottle Components Agreement shall remain in full force and effect and (b) without further action, the PET Agreement, HDPE Agreement
and the Letter Agreements will terminate and be of no further force or effect as of June 30, 2006, except as to the confidentiality obligations referenced in Section 4 below. 
 4. Confidentiality. This Settlement Agreement and the terms contained herein shall be subject to the confidentiality obligations set forth in the
1999 Supply Agreements, which obligations shall remain in full force and effect. 
 5. Applicable Law. This Settlement Agreement will
be construed in accordance with, and the rights of the parties governed by, the laws of the State of Delaware, without regard to the choice of law provisions thereof. 
 6. Entire Agreement. This Settlement Agreement constitutes the entire understanding among and between the parties hereto concerning the subject matter set forth herein, and this Settlement Agreement supersedes
any and all prior understandings, written or oral, and any and all contemporaneous oral understandings, pertaining to the subject matter set forth herein. 
 7. Voluntary Consent. All parties represent and acknowledge that in executing this Settlement Agreement, they have been afforded full opportunity to discuss all aspects of this Settlement Agreement with their
legal counsel, carefully read and fully understand all of the provisions of this Settlement Agreement and voluntarily and knowingly signed this Settlement Agreement.

 8. Binding Effect. This Settlement Agreement shall be binding upon and inure to the benefit of the
parties and their respective agents, predecessors, successors and assigns. 
 9. Counterparts. This Settlement Agreement may be
executed in any number of counterparts, each of which shall be deemed an original and all of which taken together shall constitute one and the same instrument. The parties agree that this Settlement Agreement shall be effective and binding upon the
exchange of facsimile signatures, on the condition that each party shall provide original signatures to every other party as soon as possible thereafter. 
 10. Authority. CCH and CCC hereby represent that each entity (a) has the approval of its board of directors or equivalent thereof to enter into this Settlement Agreement and (b) does not require any
third party approvals or consents to enter into this Settlement Agreement. 
 IN WITNESS WHEREOF, CCH, CCC and Dean Foods have executed this
