This SECURED CREDITOR ASSET PURCHASE AGREEMENT (the “Agreement”) is entered into as of February 23, 2010, by and between SILICON VALLEY BANK, a California State Chartered Bank, as agent for itself and for Gold Hill Venture Lending 03, LP (collectively, “Seller”), and SILICON GRAPHICS INTERNATIONAL CORP., a Delaware corporation (“Purchaser”), with the consent and acknowledgement of ERIC N. GROTHE, as the Receiver (defined below) of Copan Systems, Inc. a Delaware corporation (the “Borrower”) .

RECITALS

A. On or about March 15, 2007, Borrower entered into a Loan and Security Agreement (as amended, the “Loan and Security Agreement”) with Seller and pursuant to the Loan and Security Agreement Seller advanced loans to Borrower and Borrower owes Seller approximately $5,561,090.08. The Loan and Security Agreement together with all other documents, instruments and writings which relate to the Loan and Security Agreement are collectively referred to as the “Loan Documents.”

B. On June 25, 2008, Borrower and Silicon Valley Bank (“SVB”) entered into that certain Loan and Security Agreement (as amended, the “2008 Loan Agreement”). Borrower has no remaining obligations to SVB under the 2008 Loan Agreement and SVB has released any security interest that it may have pursuant to the 2008 Loan Agreement.

C. As security for the Loan Documents, Borrower granted to Seller a security interest in all or substantially all of Borrower’s assets, and proceeds thereof, (the “Collateral”). Lender’s security interest in the Collateral is perfected by a UCC-1 Financing Statement filed March 27, 2007 against Borrower under File No. 71147502 in the Office of the Delaware Secretary of State, as amended.

D. On or about February 9, 2009, Borrower and Westbury Investment Partners SBIC, LP, for itself and as agent, (collectively, “Junior Creditors”) entered into that certain Note Purchase and Security Agreement (as amended from time to time collectively referred to as the “Junior Security Agreement”). On or about February 9, 2009, the Junior Creditors, Borrower and the Seller entered into that certain Subordination (the “Consent”) pursuant to which the Junior Creditors expressly subordinated their right to payment under the Junior Security Agreement to all of the Borrower’s obligations to Seller.

E. Borrower is in default of its obligations under the Loan Documents for failure to make payments under the Loan Documents according to their terms, among other defaults and Seller has exercised its secured creditor rights.

F. On or about February 5, 2010, Seller filed a complaint and related pleadings in the District Court, Denver County, Colorado (“Court”) seeking the appointment of a receiver to, among other things, take over the management and control of the Collateral. On February 9, 2010, the Court entered its order appointed the Eric N. Grothe as the receiver (“Receiver”) of the Borrower (“Order”). Among other things, the Order, at section 4(v), provides: “…[the] Receiver is hereby authorized to convey to title to the Collateral on behalf of [Seller] to the fullest extent as otherwise given to a foreclosing lender under the Uniform Commercial Code and the Loan Documents, provided that the Lender has otherwise complied with the applicable provisions of the Uniform Commercial Code and the Loan Documents.”

1

G. On February 10, 2010, Seller gave notice of private sale in accordance with C.R.S. § 4-9-610 and, as a result of which, Seller is authorized pursuant to C.R.S. § 4-9-617 to transfer title to the Collateral on behalf of Borrower.

H. Seller now desires to sell certain assets (which constitute a portion of the Collateral) to Purchaser, and Purchaser desires to purchase such assets from Seller through a private foreclosure sale under C.R.S. § 4-9-610 on the terms and conditions set forth in this Agreement (the “Private Sale Transaction”).

I. The parties are entering into this Agreement to effectuate the Private Sale Transaction, subject to and conditioned upon the terms set forth in this Agreement.

4. Assignee does not hereby assume nor agree to pay, perform or discharge, and the Debtor shall remain unconditionally liable for, any and all Excluded Liabilities.

5. The assumption by Assignee of the Assumed Liabilities is not intended by the parties to expand the rights and remedies of any third party against Assignee in respect of such liabilities as compared to the rights and remedies which such third party would have had against the Debtor in respect of such liabilities had Assignee not consummated the transactions contemplated by the APA. Nothing contained herein shall, or shall be construed to, prejudice the right of Assignee to contest any claim or demand with respect to any Assigned Liability assumed hereunder and Assignee shall have all rights which the Borrower may have or have had to defend or contest any such claim or demand.
