CUSIP No. 91531F103

SCHEDULE 13D/A

The following constitutes Amendment No. 3 (“Amendment No. 3”) to the Schedule 13D filed by the undersigned on July 8, 2013 (the “Schedule 13D”), as amended by Amendment No. 1 to the Schedule 13D filed on September 17, 2013 (“Amendment No. 1”) and Amendment No. 2 to the Schedule 13D filed on September 24, 2014 (“Amendment No. 2”). This Amendment No. 3 amends the Schedule 13D as specifically set forth herein. Capitalized terms used but not defined in this Amendment No. 3 have the meanings provided in the previously filed statement on Schedule 13D.

Item 4. Purpose of Transaction.

Item 4 is hereby amended and supplemented with the following:

The responses to Items 3, 5 and 6 of the previously filed statement on Schedule 13D, as amended by Amendment No. 1, Amendment No. 2 and this Amendment No. 3, are incorporated herein by reference.

The shares of Common Stock of the Issuer to which this Schedule 13D relates were acquired for investment purposes in the ordinary course of business.

Pursuant to the Section 7(b)(1) of the Securities Purchase Agreement between the Issuer and the Fund, dated June 28, 2013 (the “Securities Purchase Agreement”), the Fund has the right to designate one (1) member to the Issuer’s Board of Directors (the “Designated Director”) provided that such designee meets the criteria that are reasonably acceptable to the nominating committee (or equivalent committee or the full board, as applicable) of the Issuer’s Board of Directors; provided that the Fund shall only have the right to designate the Designated Director so long as the Fund (i) maintains a voting percentage equal to or greater than 5% of the total shares outstanding or (ii) maintains a voting percentage equal to or greater than 3% of the total shares outstanding and holds at least 50% of the senior secured notes issued under the Note Purchase Agreement (the “Holding Requirements”) (the right to designate the Designated Director, the “Director Designation Right”). Additionally, pursuant to Section 7(b)(2) of the Securities Purchase Agreement, from and after June 28, 2016 until such time as the Fund no longer meets the Holding Requirements, the Fund shall have the right to designate one (1) additional member to the Issuer’s Board of Directors (the “Additional Designated Director”) provided that such designee meets the criteria that are reasonably acceptable to the nominating committee (or equivalent committee or the full board, as applicable) of the Issuer’s Board of Directors. The Issuer shall have the right to block a Designated Director or an Additional Designated Director if such designee holds, or is nominated to hold, a management position or board seat at a company that the Issuer’s Board of Directors reasonably determines directly competes with the Issuer. In addition, the right to designate (and maintain the right to designate) the Designated Director and/or the Additional Designated Director shall at all times be subject to applicable rules and published guidance of The NASDAQ Stock Market LLC, including, but not limited to, listing rule 5640 (or any successor rule) and will depend in part on the designating party’s ownership percentage as of the time of the applicable designation.

A copy of the Securities Purchase Agreement was previously filed as Exhibit 2 to the original Schedule 13D filed by the Reporting Persons on July 8, 2013, and is incorporated herein by reference, and the preceding summary of the Securities Purchase Agreement is qualified in its entirety by reference thereto. This Schedule 13D does not purport to amend, qualify or in any way modify such agreement.

On September 22, 2014, the General Partner sent a letter to the Issuer on behalf of the Fund designating Andrew M. Dodge as a member of the Issuer’s Board of Directors pursuant to the Director Designation Right described above. On September 26, 2014, the Issuer’s Board of Directors appointed Mr. Dodge to the Board of Directors as a director. The appointment was effective on September 30, 2014. Mr. Dodge was reelected as a member of the Issuer’s Board of Directors at the Issuer’s annual shareholder meeting held on November 3, 2014.

On May 20, 2015, Mr. Dodge submitted a letter to the Issuer’s Board of Directors whereby he resigned as a member of the Issuer’s Board of Directors, effective immediately.

To continue support of the Board of Directors and Issuer’s management in their effort to maximize shareholder value, and in furtherance of the transactions pursuant to the Purchase Agreement and Assignment Agreement (as defined below) described in this Item 4, on May 21, 2015, the General Partner sent a letter to the Issuer on behalf of the Fund designating Peter A. Reed, a designee deemed satisfactory to the Buyer (as defined below), to replace Mr. Dodge as a member of the Issuer’s Board of Directors pursuant to the Director Designation Right described above.

Additionally, on May 21. 2015, the Fund entered into a Securities Purchase Agreement (the “Purchase Agreement”) with certain funds managed by MAST Capital Management, LLC (collectively, the “Buyer”), pursuant to which the Fund agreed to sell and the Buyer agreed to purchase, subject to the satisfaction of or waiver of certain conditions, including the Issuer acknowledging the Fund’s assignment, and the Buyer’s assumption, of the Director Designation Right, (i) 5,500,000 shares of

CUSIP No. 91531F103

SCHEDULE 13D/A

Common Stock held by the Fund at a price per share equal to $0.8829, and (ii) senior secured notes due 2018 (the “Notes”) issued by the Issuer pursuant to an Indenture dated as of June 28, 2014 (as amended from time to time, the “Indenture”) with an aggregate Note Balance (as defined in the Indenture) of $31,228,492, for a purchase price that is 109.65625% of the then current aggregate Note Balance, plus the amount of interest accrued but unpaid through the date that is the earlier of (i) consummation of the Note Transaction (as defined in the Purchase Agreement) in accordance with the terms of the Purchase Agreement and (ii) 20 business days following the date of the Purchase Agreement (the “Note Accrual Date”), determined as if the interest on the Notes were payable in cash rather than as a PIK Payment (as defined in the Indenture). All interest from and after the Note Accrual Date shall be for the account of the Buyer. Pursuant to the Purchase Agreement and the Director Designation Right Assignment Agreement, dated as of May 21, 2015, by and among the Fund and the Buyer (the “Assignment Agreement”), the Fund agreed to sell and assign to the Buyer, and the Buyer agreed to purchase and assume from the Fund, the Board Designation Right. The consummation of the assignment and assumption of the Board Designation Right is subject to the Issuer indicating its consent and acceptance of such assignment and assumption by execution of the Assignment Agreement and the satisfaction of or waiver of the same conditions precedent to the consummation of the other transactions set forth in the Purchase Agreement. The assignment and assumption of the Board Designation Right shall be effective at such time as the other transactions set forth in the Purchase Agreement are consummated. For the avoidance of doubt, the Fund maintains its right to designate an Additional Designated Director pursuant to, and in accordance with, Section 7(b)(2) of the Securities Purchase Agreement.

Copies of the Purchase Agreement and the Assignment Agreement are attached hereto as Exhibit 1 and Exhibit 2, respectively, and are incorporated herein by reference, and the preceding summaries of the Purchase Agreement and the Assignment Agreement are qualified in their entirety by reference to the full texts of the respective agreements. This Schedule 13D does not purport to amend, qualify or in any way modify such agreements.

No Reporting Person has any present plan or proposal which would relate to or result in any of the matters set forth in subparagraphs (a) - (j) of Item 4 of Schedule 13D, except as set forth herein or such as would occur upon completion of any of the actions discussed above. The Reporting Persons intend to review their investment in the Issuer on a continuing basis. Depending on various factors, the Reporting Persons may in the future take such actions with respect to their investment in the Issuer as they deem appropriate including, without limitation, engaging in discussions with management, the Board of Directors, other shareholders of the Issuer and other relevant parties, including representatives of any of the foregoing, concerning matters with respect to the Reporting Persons’ investment in the Issuer, purchasing additional Common Stock, selling some or all of their Common Stock, purchasing additional Notes, selling some or all of their Notes, engaging in hedging or similar transactions with respect to their investment in the Issuer and/or otherwise changing their intention with respect to any and all matters referred to in Item 4 of this Schedule 13D.

Item 5. Interest in Securities of the Issuer.

Items 5(a), 5(b) and 5(c) are each hereby amended and restated to read as follows:

Pursuant to Rule 13d-3 of the rules and regulations promulgated by the Commission pursuant to the Exchange Act: (i) the Fund may be deemed to beneficially own the 12,068,780 shares of Common Stock that it holds, representing approximately 10.8% of the Common Stock outstanding; (ii) in its capacity as the sole investment manager of the Fund, the Investment Manager may be deemed to beneficially own 12,068,780 shares of Common Stock, representing approximately 10.8% of the Common Stock outstanding; (iii) in its capacity as the sole general partner of the Fund, the General Partner may be deemed to beneficially own 12,068,780 shares of Common Stock, representing approximately 10.8% of the Common Stock outstanding; (iv) in its capacity as the sole general partner of the Investment Manager, IC GP may be deemed to beneficially own 12,068,780 shares of Common Stock, representing approximately 10.8% of the Common Stock outstanding; and (v) in his capacity as the sole Managing Member of IC GP and the sole Senior Managing Member of the General Partner, the Senior Managing Member may be deemed to beneficially own 12,068,780 shares of Common Stock, representing approximately 10.8% of the Common Stock outstanding.

Each of the of the Executive Officers and other partners and members of the Investment Manager and the General Partner other than the Senior Managing Member disclaims beneficial ownership of the shares of Common Stock that any of the Investment Manager, IC GP or the General Partner may be deemed to beneficially own. The Reporting Persons specifically disclaim beneficial ownership in the shares of Common Stock reported herein, and this Schedule 13D, as amended, shall not be deemed an admission that any of the Reporting Persons is the beneficial owner of such securities for purposes of Section 13(d) or for any other purpose, except to the extent any such Reporting Person actually exercises voting or investment power with respect to such securities.

ARTICLE II. REPRESENTATIONS, WARRANTIES, AND AGREEMENTS

Section 2.01 Buyer’s Representations, Warranties, and Agreements. Each of Buyer and, solely with respect to clauses (d) and (e) below, MAST, represents, warrants, and agrees as of the date hereof and as of the Transaction Settlement Date (as defined below) (and such representations, warranties, and agreements shall survive the sale and delivery of the Offered Securities hereunder for a period of two years from the Transaction Settlement Date, except that the representations, warranties, and agreements set forth in clauses (d) and (e) shall survive through the applicable statute of limitations) as follows:

(a) Buyer has carefully reviewed (i) the financial statements filed with the Securities and Exchange Commission by the Issuer, and (ii) such other information that it and its advisors deem necessary to make its decision to enter into the Transactions.

(b) Buyer possesses and has reviewed a copy of the Indenture, including but not limited to the restrictions on transfer set forth in Section 2.04 thereof. Buyer understands that the Notes may be offered, resold, pledged or otherwise transferred only as contemplated in the Indenture and the Notes.

(c) Buyer (i) has such knowledge and experience in financial and business matters as to be capable of evaluating the merits and risks of the Transactions and is consummating the Transactions with a full understanding of all of the terms, conditions, and risks and willingly assumes those terms, conditions, and risks, (ii) has adequate information concerning the Offered Securities, (iii) has adequate information concerning the business and financial condition of the Issuer and any of its affiliates, (iv) acknowledges that it has sole responsibility for its own due diligence investigation and its own investment decision and (v) it has made its own informed decision to consummate the Transactions based on its own independent review and consultations with such investment, legal, tax, accounting and other advisors as it deemed necessary and is not relying on Seller or Seller’s affiliates, and each of its and such affiliates’ respective directors, officers, employees, partners, members and agents for any investment, legal, tax or accounting advice. Buyer has made its own decision concerning the Transactions without reliance on any representation or warranty by, or advice from, Seller or Seller’s affiliates, and each of its and such affiliates’ respective directors, officers, employees, partners, members and agents regarding the Offered Securities, the Issuer and/or the Transactions (other than representations and warranties set forth in this Agreement).

(d) Seller and Indaba have informed Buyer and MAST, and Buyer and MAST each acknowledges and understands, that each of Seller and Indaba may have possession of, or may have received or obtained, confidential or material, non-public information concerning the Offered Securities and/or the Issuer (collectively, “Excluded Information”), which is not known to Buyer or MAST and, if publicly disclosed, could affect the trading price of the Offered Securities. Buyer and MAST each acknowledges and understands, based on its experience, the disadvantage to which Buyer and MAST may be subject due to any disparity of information between Buyer and MAST on the one hand and Seller and Indaba on the other. Notwithstanding any possession of Excluded Information by Seller or Indaba and the absence of disclosure thereof to Buyer or MAST, each of Buyer and MAST has deemed it appropriate, and desires, to engage in the Transactions for its own business purposes.

(e) Buyer and MAST each agrees that none of Seller, Indaba their respective affiliates, or any of their and such affiliates’ respective directors, officers, employees, partners, members and agents (collectively, the “Released Persons”) shall have any liability whatsoever to Buyer or MAST due to Seller’s or Indaba’a use and/or non-disclosure of any Excluded Information, and Buyer and MAST each hereby irrevocably (i) waives any and all actions, causes, rights or claims, whether known or unknown, contingent or matured, and whether currently existing or hereafter arising, that it may have or hereafter acquire (“Claims”) against the Released Persons, directly or indirectly, arising out of or resulting from Seller’s or Indaba’s failure to disclose any Excluded Information to Buyer or MAST, including, without limitation, Claims it may have under applicable federal and/or state securities laws, and (ii) expressly releases the Released Persons from any and all liabilities that may arise from Seller’s or Indaba’s failure to disclose any Excluded Information. Buyer and MAST each agrees that it shall not institute or maintain any cause of action, suit or complaint or other proceeding against any Released Person as a result of Seller’s failure to disclose any Excluded Information to Buyer.

(f) Buyer is:

(i) a “qualified institutional buyer” (as defined in Rule 144A under the Securities Act of 1933, as amended (the “Securities Act”)), and

(ii) a “qualified purchaser” (as defined in Section 2(a)(51)(A) of the Investment Company Act of 1940).

(g) Buyer is acquiring its interest in the Offered Securities solely for its own account for investment purposes only and not with a view towards the resale or distribution thereof in violation of the Securities Act.

(h) Except for rights to purchase the Offered Securities pursuant to this Agreement, Buyer does not own any Common Stock of the Issuer, any options or warrants to acquire such Common Stock, any securities exercisable for, convertible into, or exchangeable for such Common Stock, or own or possess any other right (contractual or otherwise) to purchase or acquire such Common Stock.

(i) Buyer (i) is duly organized, validly existing and in good standing under the laws of the jurisdiction of its organization and (ii) has all requisite power and authority to execute and deliver this Agreement and to consummate the transactions described herein.

(j) The execution and delivery by Buyer of this Agreement and the performance by Buyer of its obligations hereunder have been duly authorized by all requisite action on the part of Buyer. Assuming due authorization, execution and delivery by Seller, this Agreement is a legal, valid and binding obligation of Buyer, enforceable against Buyer in accordance with its terms, except that such enforcement (i) may be limited by bankruptcy, insolvency, moratorium or similar laws affecting creditors' rights generally and (ii) is subject to the availability of equitable remedies, as determined in the discretion of the court before which such a proceeding may be brought.

(k) The Offered Securities offered by Seller to Buyer were not offered to Buyer by means of general solicitation or general advertising within the meaning of Rule 502(c) under the Securities Act, and the rules and regulations promulgated thereunder.

(l) Buyer acknowledges and agrees that Seller is relying on Buyer’s representations, warranties, and agreements herein as a condition to proceeding with the Transactions. Without such representations, warranties, and agreements, Seller would not engage in the Transactions.

Section 2.02 Seller’s Representations, Warranties, and Agreements. Seller represents, warrants, and agrees as of the date hereof and as of the Transaction Settlement Date (and such representations, warranties, and agreements shall survive the sale and delivery of the Offered Securities hereunder for a period of two years from the Transaction Settlement Date except that the representations, warranties, and agreements set forth in clause (c) shall survive through the applicable statute of limitations) as follows:

(a) Seller possesses and has reviewed a copy of the Indenture, including but not limited to the restrictions on transfer set forth in Section 2.04 thereof. Seller understands that the Notes may be offered, resold, pledged or otherwise transferred only as contemplated in the Indenture and the Notes.

Seller has made its own decision concerning the Transactions without reliance on any representation or warranty by, or advice from, Buyer or Buyer’s affiliates, and each of its and such affiliates’ respective directors, officers, employees, partners, members and agents regarding the Offered Securities, the Issuer and/or the Transactions (other than representations and warranties set forth in this Agreement).

(c) Each of Seller and Indaba confirms that neither it nor, to its knowledge, any other person or entity acting on its behalf has provided Buyer or MAST with any information that constitutes or could reasonably be expected to constitute Excluded Information concerning the Issuer, other than information regarding the Transactions (including, without limitation, the resignation of Andrew Dodge as a member of the Issuer’s Board of Directors). Each of Seller and Indaba acknowledges and agrees that neither Buyer nor MAST has requested from Seller or Indaba, and neither Seller nor Indaba has provided to Buyer or MAST, any Excluded Information.

(e) The execution and delivery by Seller of this Agreement and the performance by Seller of its obligations hereunder have been duly authorized by all requisite action on the part of Seller.

(f) Seller is the sole record, legal and beneficial owner of the Notes and the sole beneficial owner of the Offered Shares, has good title to the Offered Securities, and Seller's right, title and interest in the Offered Securities are free and clear of all liens, claims, encumbrances, voting trusts, voting agreements, transfer restrictions and other restrictions of any nature whatsoever, other than the transfer restrictions that may be imposed under the Indenture and applicable securities laws.

(g) Other than pursuant to this Agreement, Seller has not granted, created or entered into any currently existing option, purchase agreement, redemption agreement, call or right to subscribe of any character relating to the Offered Securities.

(h) The Offered Securities offered by Seller to Buyer were not offered to Buyer by means of general solicitation or general advertising within the meaning of Rule 502(c) under the Securities Act, and the rules and regulations promulgated thereunder.
