(b)                                  Provisions of this Agreement that apply to conversion of all of a Note also apply to conversion of a portion of a Note.

(c)                                   A Holder of Notes is not entitled to any rights of a holder of Common Stock until such Holder has converted its Notes to Shares, and only to the extent such Notes are deemed to have been converted into Shares pursuant to this Section 4.

(d)                                  A Holder of Notes is not entitled to exercise the conversion right under Section 4.1(a) if the conversion would result in a violation of Section 8.2 by the Holder.

4.2                                Conversion Procedure .

(a)                                  To convert a Note, a Holder must (1) complete and manually sign the conversion notice included in the Note and deliver such notice to the Company, (2) surrender the Note to the Company, (3) furnish appropriate endorsements and transfer documents if required by the Company’s transfer agent or the Company, and (4) pay any transfer or similar tax, if required.  The date on which the Holder satisfies all of these requirements is the “ Conversion Date .”

(b)                                  A Note in respect of which a Holder has delivered a Repurchase Exercise Notice pursuant to Section 3.1 may be converted pursuant to Section 4.1 only if such notice is withdrawn by a written notice of withdrawal delivered to the Company prior to 5:00 p.m. New York City time on the second Business Day immediately preceding the Fundamental Change Repurchase Date in accordance with Section 3.1.

(c)                                   The Company shall deliver any Shares and cash in lieu of any fractional shares deliverable upon conversion to the respective Holders for their accounts no later than the third Business Day on or after the Conversion Date.

13

(d)                                  The person in whose name the certificate for the Shares is registered shall be deemed to be a stockholder of record on the Conversion Date; provided , however , that no surrender of a Note on any date when the stock transfer books of the Company shall be closed shall be effective to constitute the person or persons entitled to receive the shares of Common Stock upon such conversion as the record holder or holders of such shares of Common Stock on such date, but such surrender shall be effective to constitute the person or persons entitled to receive such shares of Common Stock as the record holder or holders thereof for all purposes at the close of business on the next succeeding day on which such stock transfer books are open; provided, further, that such conversion shall be at the Conversion Rate based on the Applicable Conversion Price in effect on the Conversion Date as if the stock transfer books of the Company had not been closed.  Upon conversion of a Note, such person shall no longer be a Holder of such Note.  No payment or adjustment will be made for dividends or distributions on shares of Common Stock issued upon conversion of a Note.

(e)                                   Except as otherwise provided in this Section 4.2, the Company’s delivery to the Holder of the full number of Shares into which the Note is convertible, together with any cash payment for such Holder’s fractional shares pursuant to Section 4.3, shall be deemed to satisfy the Company’s obligation to pay the principal amount of the Note and accrued but unpaid interest, if any, attributable to the period from the most recent interest payment date to the conversion date.  As a result, accrued but unpaid interest, if any, to the Conversion Date is deemed to be paid in full rather than cancelled, extinguished or forfeited.

In no event will the Company take any action that would require adjustment to the Applicable Conversion Price, nor will the Company adjust the Applicable Conversion Price, if such Applicable Conversion Price adjustment would require the Company to, issue, upon conversion of the Notes, a number of shares of Common Stock that would require the Company to obtain prior stockholder approval under the listing rules of the Nasdaq Stock Market, and, if applicable, the rules of any other national securities exchange on which the Common Stock is then traded, without obtaining such prior stockholder approval.

(b)                                  The Applicable Conversion Price shall be subject to adjustment, without duplication, upon the occurrence of any of the following events:

(1)                                  In the event the Company pays a dividend or makes a distribution on the Common Stock, payable exclusively in shares of Common Stock, the Applicable Conversion Price in effect immediately before the close of business on the record date fixed for determination of stockholders entitled to receive that dividend or distribution shall be decreased by multiplying:

(x)                                  the Applicable Conversion Price, by

(y)                                  a fraction, (A) the numerator of which shall be the number of shares of Common Stock outstanding immediately before the close of business on such record date, and (B) the denominator of

15

which shall be the sum of the number of shares of Common Stock outstanding immediately before the close of business on such record date and the total number of shares constituting such dividend or other distribution.

(2)                                  In the event the Company:

(A)                                subdivides or splits the outstanding shares of Common Stock into a greater number of shares, the Applicable Conversion Price shall be proportionally decreased immediately after the effective date of such subdivision or split;

(B)                                combines or reclassifies the outstanding shares of Common Stock into a smaller number of shares, the Applicable Conversion Price shall be proportionally increased immediately after the effective date of such combination or reclassification; or

(3)                                  In the event the Company distributes shares or other equity interests of any subsidiary or other entity now or hereafter owned by the Company to the stockholders of the Company pro rata, as a matter of right, without the payment or exchange of consideration by the stockholders, in addition to the Shares issuable upon conversion by the Holder of a Note pursuant to Section 4.1 the Holder also shall receive the number of shares or other equity interests of such subsidiary or other entity which the Holder would have been entitled to receive if the Holder had owned the Common Stock issuable under the Notes, which the Holder has elected to convert, immediately prior to the date of such distribution by the Company.  For purposes of this Agreement and the Note, the term “Shares” shall be deemed to include the additional equity interests provided under this subsection 4.6(b)(3) where necessary to give effect to this provision.

(c)                                   In addition to the adjustments set forth in Section 4.6(a) and (b), the Company may increase the Applicable Conversion Rate as the Board of Directors considers advisable to avoid or diminish any income tax to holders of Common Stock or rights to purchase Common Stock resulting from any dividend or distribution of Capital Stock (or rights to acquire Capital Stock) or from any event treated as such for income tax purposes.

4.7                                Notice of Adjustments of Conversion Rate .  Whenever the Applicable Conversion Price is adjusted pursuant to Section 4.6 hereof:

9.3      Other Remedies .  If an Event of Default occurs and is continuing, the Holders of at least a Majority-in-Interest of the Notes may, but shall not be obligated to, pursue any available remedy by proceeding at law or in equity to collect the payment of the principal of or interest on the Notes or to enforce the performance of any provision of the Notes or this Agreement.  A delay or omission in exercising any right or remedy accruing upon an Event of Default shall not impair the right or remedy or constitute a waiver of or acquiescence in the Event of Default.  No remedy is exclusive of any other remedy.  All available remedies are cumulative to the extent permitted by law.

9.4      Waiver of Defaults and Events of Default .  Subject to Section 9.6, the Holders of a Majority-in-Interest of the Notes then outstanding by notice to the Company may waive an existing default or Event of Default and its consequence, except a default or Event of Default in the payment of the principal of, premium, if any, or interest on any Note, a failure by the Company to convert any Notes into Shares in accordance with the provisions of the Notes and this Agreement or any default or Event of Default in respect of any provision of this Agreement or the Notes which, under Section 9.6, cannot be modified or amended without the consent of the

27

Holder of each Note affected.  When a default or Event of Default is waived, it is cured and ceases.

9.5      Limitations on Suits .  A Holder may not pursue any remedy with respect to this Agreement or the Notes (except actions for payment of overdue principal or interest or for the conversion of the Notes pursuant to Section 4) unless:

(1)           the Holder gives to the Company written notice of a continuing Event of Default; and

(2)           the Holders of at least 25% in aggregate principal amount of the then outstanding Notes make a written request to the Purchasers’ Agent to pursue the remedy.

A Holder may not use this Agreement to prejudice the rights of another Holder or to obtain a preference or priority over such other Holder.

9.6      Rights of Holders to Receive Payment and to Convert .  Notwithstanding any other provisions of this Agreement other than Section 9.2 and Section 9.4, the right of any Holder of a Note to receive payment of the principal of and interest on the Note, on or after the respective due dates expressed in the Note and this Agreement, to convert such Note in accordance with Section 4 and to bring suit for the enforcement of any such payment on or after such respective dates or the right to convert, is absolute and unconditional and shall not be impaired or affected without the consent of the Holder.

(1)                                  First, to the payment of the reasonable costs and expenses of Purchasers’ Agent and the Purchasers in exercising or enforcing their rights hereunder, including, but not limited to, costs and expenses incurred in retaking, holding or preparing the Collateral for sale, lease or other disposition, and to the payment of all expenses of the Purchasers pursuant to Section 6.4;

5

EXERCISE ANY RIGHT HEREUNDER, SHALL NOT CONSTITUTE A WAIVER OF ANY OBLIGATION OF THE COMPANY HEREUNDER, OR ANY RIGHT OF PURCHASERS’ AGENT’S OR THE PURCHASERS HEREUNDER, AND SHALL NOT AFFECT IN ANY WAY THE RIGHT TO REQUIRE FULL PERFORMANCE AT ANY TIME THEREAFTER.

5.                                       APPOINTMENT OF AGENT.

Without limiting the generality of the foregoing, Purchasers’ Agent shall be entitled under this Agreement upon the occurrence and continuation of any Event of Default (i) to ask, demand, collect, sue for, recover, receive and give receipt and discharge for amounts due and to become due under and in respect of all or any part of the Collateral; (ii) to receive; endorse and collect any instruments, documents and chattel paper in connection with clause (i) above (including any draft or check representing the proceeds of insurance or the return of unearned premiums); (iii) to file any claims or take any action or proceeding that Purchasers’ Agent may deem necessary or advisable for the collection of all or any part of the Collateral, including the collection of any compensation due and to become due under any contract or agreement with respect to all or any part of the Collateral; and (iv) to execute, in connection with any sale or disposition of the collateral under Section 4, any endorsements, assignments, bills of sale or other instruments of conveyance or transfer with respect to all or any part of the Collateral.

5.2                                Payments Pro Rata .  Purchasers’ Agent and the Purchasers agree that payments to the Purchasers under the Notes shall be made in proportion to the principal and accrued interest then outstanding under each Note on any such date of payment to each, until such obligations are paid or retired in full.

5.3                                Sharing of Payments .  If any Purchaser shall at any time receive any payment of principal, interest or other charge arising under a Note, or upon any other obligation of the Company or any sums by virtue of counterclaim, offset, or other lien that may be exercised, or from any security, other than payments made on the same date and pro rata to all the Purchasers, such Purchaser shall return such payment to Purchasers’ Agent, who shall immediately dispense such payment or payments ratably among all the Purchasers so as to maintain as near as possible the unpaid balance of the loans pro rata according to the Purchasers’ proportionate interests.

The Company shall pay interest semiannually on August 15 and February 15 of each year, commencing on August 15, 2016. Interest on the Notes shall accrue from the most recent date to which interest has been paid or, if no interest has been paid, from the Purchase Agreement Closing Date; provided , however , that if there is not an existing default in the payment of interest and if this Note is authenticated between a record date referred, to on the face hereof and the next succeeding interest payment date, interest shall accrue from such interest payment date.

If there is no pending Event of Default under the Loan Documents as of the interest payment date for which interest will be paid the Company may, however, upon 15 days’ prior written notice to the Holder or Purchaser’s Agent, pay interest due by issuing a new Note in the principal amount of the interest due, and in all other respects having terms identical to this Note, and may convert accrued and unpaid interest as of the Conversion Date into Shares in accordance with Section 2.8 of the Purchase Agreement. The Company will pay principal due upon surrender of Notes by check sent to the Holder’s address on the books and records of the Company, or, if the Holder has provided wire transfer instructions to the Company at least five Business Days prior to the payment date, in immediately available funds by wire transfer.

3.                                       PURCHASE AGREEMENT

This Note is one of a duly authorized issue of Notes of the Company designated as its 10% Senior Secured Convertible Notes Due August 15, 2018 (the “Notes”) issued under the Purchase Agreement.

This Note is secured by all of the assets of the Company in accordance with the terms and subject to the conditions of the Security Agreement dated as of the Purchase Agreement Closing Date among the Company, Purchasers’ Agent, and the Purchasers. In case of an Event of Default, the Purchasers shall have the rights set forth in the Security Agreement; provided that such rights shall be subject to such senior or contemporaneous rights of the Senior Lender as

2

may be agreed by Purchasers’ Agent and the Company with the Senior Lender as permitted under the Purchase Agreement.

5.                                       DEFAULT

If an Event of Default shall occur, the aggregate unpaid principal balance plus accrued and unpaid interest on this Note shall become or may be declared to be due and payable in the manner and with the effect provided in the Loan Documents.

6.                                       REPURCHASE OF NOTES AT OPTION OF HOLDER UPON A FUNDAMENTAL CHANGE

A.            Subject to the terms and conditions of the Purchase Agreement, if a Fundamental Change occurs at any time prior to the Maturity Date, the Holder will, upon receipt of the notice of the occurrence of a Fundamental Change, have the right to require the Company to repurchase any or all of such Holder’s Notes for cash in an amount equal to 120% of the principal amount of the Notes to be repurchased plus accrued and unpaid interest, if any, to (but not including) the Fundamental Change Repurchase Date, unless such Fundamental Change Repurchase Date falls after an interest payment record date and on or prior to the corresponding interest payment date, in which case the Fundamental Change Repurchase Price will include the full amount of accrued and unpaid interest payable on such interest payment date to the Holder of record at the close of business on the corresponding interest payment record date. Subject to Section 3.1 of the Purchase Agreement, on or before the 10 th  Business Day prior to the effective date of a Fundamental Change, or as soon as practicable after the occurrence of a Fundamental Change described in Section 1.11(c) of the Purchase Agreement, the Company will provide to the Holder and Purchasers’ Agent a notice of the occurrence of the Fundamental Change and of the resulting repurchase right.

C.            All interest shall cease to accrue on this Note (or portions thereof) immediately after such Fundamental Change Repurchase Date, and the Holder shall have no other rights as such other than the right to receive the Fundamental Change Repurchase Price upon surrender of the Note.

7.                                       OPTIONAL CONVERSION

A.            The Holder, at the Holder’s sole option, may convert the principal amount of this Note (or any portion thereof equal to $100,000 or any integral multiple of $100,000 in excess thereof) into Shares, and/or such other consideration as provided in Section 4 of the Purchase Agreement, at any time prior to the close of business on the last Business Day prior to the Maturity Date, at the Applicable Conversion Price (which is the Initial Conversion Price as adjusted from time to time in accordance with the Purchase Agreement) in effect on the

3

Conversion Date; provided, however, that, if such Note is submitted or presented for purchase pursuant to Section 3.1 of the Purchase Agreement, such conversion right shall terminate at the close of business on the Business Day immediately preceding the Fundamental Change Repurchase Date for such Note, or such earlier date as the Holder presents such Note for repurchase (unless the Company shall default in making the Fundamental Change Repurchase Price payment when due, as the case may be, in which case the conversion right shall terminate at the close of business on the date such default is cured and such Note is redeemed or purchased, as the case may be).  The Initial Conversion Price is $0.90 per Share, and the initial Conversion Rate is one Share per $0.90 principal amount of Note.  The Initial Conversion Price and the Conversion Rate are subject to adjustment as provided in the Purchase Agreement. All accrued and unpaid interest on the Note through the Business Day immediately preceding the Conversion Date shall be paid in accordance with Paragraph 2, provided that if the Company elected to pay the interest with the issuance of a new Note thereof, the full amount thereof shall be converted into additional Shares as Note principal.  Upon surrender of this Note for conversion and timely delivery to the Company of the Holder’s conversion notice (which may be submitted on Holder’s behalf by Purchaser’s Agent), the Company will issue, or will cause its transfer agent to issue, the Shares to the Holder on the requested Conversion Date.  No fractional Shares will be issued upon conversion; in lieu thereof, an amount will be paid in cash based upon the Closing Sale Price of the Common Stock on the Trading Day immediately prior to the Conversion Date.  The Shares when issued may be represented by book entry, or by certificates if so requested by Holder.

B.            To convert this Note under Paragraph 7A, the Holder must (a) complete and manually sign the conversion notice set forth below and deliver such notice to the Company at least 15 days in advance of the Conversion Date, (b) surrender the Note to the Company, (c) furnish appropriate endorsements and transfer documents if required by the transfer agent or the Company, and (d) pay any transfer or similar tax, if required.

C.            If Holder has delivered a Fundamental Change Repurchase Right Notice exercising the option of the Holder to require the Company to repurchase this Note, then this Note may be converted pursuant to Paragraph 7A only if the Fundamental Change Repurchase Right Notice is withdrawn by the Holder in accordance with the terms of the Purchase Agreement.

8.                                       DENOMINATIONS, TRANSFER, EXCHANGE

The Notes are issued without coupons in denominations of $100,000 and integral multiples of $100,000 and are recorded in the name of the Holder on the books and records of the Company. The Holder may register the transfer of or exchange of this Note in accordance with the Purchase Agreement.
