Interest shall accrue on the Accreted Principal Amount at an annual rate equal to 11.50% (or, from and after any extension of the maturity date of this Note under Section 2.1 below, 9.50%) per annum, of which amount (a) 6.50% shall be payable in cash on each Interest Payment Date and (b) 5.0% (or, from and after any extension of the maturity date of this Note under Section 2.1 below, 3.0%) shall be payable by adding such interest to the Accreted Principal Amount on each Interest Payment Date (as defined below), and on the final maturity hereof (the "PIK Amount"). At any time, the outstanding principal amount of this Note, including all PIK Amounts and Default PIK Amounts (as defined below) added thereto through such time, is referred to in this Note as the "Accreted Principal Amount" (in each case computed on the basis of a 365/366-day year and the actual number of days elapsed in any year) on the unpaid principal amount of this Note outstanding from time to time, or (if less) at the highest rate then permitted under applicable law. The Company shall pay to the holder of this Note all accrued interest (including Contingent Additional Interest as described below) on the first day of each July and January (each, an "Interest Payment Date" ) and on the final maturity date of this Note. Any accrued cash interest which for any reason has not theretofore been paid shall increase the principal of the Note and be paid in full on the date on which the final principal payment on this Note is made (the "Default PIK Amounts"); provided that any such reason shall not affect or waive any Event of Default that arises due to the failure to make such payment in cash. Interest shall accrue on any principal payment due under this Note (including as to accrued interest added to the principal) until such time as payment therefore is actually delivered to the holder of this Note.

However, if the Failure Term runs for more than three months, the additional monthly cash interest payable thereafter shall increase, to the extent permitted by law, to the greater of $10,000 or 1% of the outstanding principal balance on this Note as of the last day of the prior month.

Notwithstanding any provision in this Section 4.1(a) to the contrary (x) the Company shall not be prohibited from making, and the holder(s) of the Note shall not be prohibited from receiving, payments of interest upon the Note under clause (iii) of the preceding sentence for more than aggregate of 180 days within any period of 365 consecutive days; (y) no Company Default existing on the date any Senior Non-Payment Default Notice is given pursuant to this Section 4.1(a) shall, unless the same shall have ceased to exist for a period of at least 30 consecutive days, be used as the basis for any subsequent such notice; and (z) the failure of the Company to make any payment with respect to the Note by reason of the operation of this Section 4.1(a) shall not be construed as preventing the occurrence of a default under any loan agreement, credit agreement, security agreement, letter of credit, reimbursement agreement or other document or instrument evidencing or securing the Note.

  (b) If any cash payment is made on the Note at a time when the holders are not entitled to receive cash payments on the Note, the payment or distribution shall be delivered directly to the Agent for application against the Senior Indebtedness, unless and until all principal and interest on the Senior Indebtedness has been paid in full and the commitments, if any, of the holders of the Senior Indebtedness to extend credit accommodations to Quantum or the Company have expired, except that

  • • (i) no such delivery shall be made of stock or obligations issued by the Company or any corporation succeeding to the Company or acquiring its property and assets, pursuant to reorganization proceedings or dissolution or liquidation proceedings or upon any merger, consolidation, sale, lease, transfer or other disposal, if such stock or obligations are subordinate and junior at least to the extent provided hereunder to the payment of Senior Indebtedness to the extent then outstanding and to the payment of any stock or obligations which are concurrently therewith issued in exchange for Senior Indebtedness to the extent then outstanding, and

      (ii) if any holder of Senior Indebtedness receives any payment or distribution that, except for the provisions of this Section 4.1, would have been payable or deliverable with respect to the Note, the holders of the Note shall (after all principal and interest owing on such Senior Indebtedness has been paid in full and the commitments, if any, of the holders of the Senior Indebtedness to extend credit accommodations to Quantum or the Company have expired) be subrogated to the rights of such holders of such Senior Indebtedness against the Company.

  (c) Until all Senior Indebtedness has been paid in full and the commitments, if any, of the holders of the Senior Indebtedness to extend credit accommodations to Quantum or the Company have expired, the holders of the Note shall not, without the prior written consent of the Agent, take any Enforcement Action with respect to the

4

• Notes or any Collateral, until the earlier to occur of the following and in any event no earlier than ten (10) days after the Agent’s receipt of written notice from such holder of the Note of its intention to take such Enforcement Action (which notice may be issued during the 180 day period referred to in clause (iii) below with respect to an Enforcement Action that such holder of the Note has the right to commence upon the expiration of said 180 day period):

Notwithstanding the foregoing, but subject in all events to the provisions of Section 4.4, any holder of the Note may file proofs of claim against the Company in any Insolvency Proceeding involving the Company. Except for distributions of the type specified in Section 4(b)(i), any distributions or other proceeds of any Enforcement Action obtained by any holder of the Note shall in any event be held in trust by it for the benefit of the holders of the Senior Indebtedness and promptly paid or delivered to the Agent in the form received until all Senior Indebtedness has been paid in full and the commitments, if any, of the holders of the Senior Indebtedness to extend credit accommodations to Quantum or the Company have expired. Notwithstanding anything contained herein to the contrary, if following the acceleration of the Senior Indebtedness, such acceleration is rescinded (whether or not any existing Company Default has been cured or waived), then all Enforcement Actions taken by any holder of the Note shall likewise be rescinded if such Enforcement Action is based solely on clause (i) of this Section 4.1(c). Notwithstanding anything herein to the contrary, no provision herein shall prevent any holder of the Note from initiating a legal action or proceeding solely to the extent necessary to prevent the running of any applicable statute of limitation or similar restriction on claims.

      (iii) any amendment increasing the interest rate payable with respect to the Note to an interest rate that is 200 basis points more than the interest rate applicable to the Note on the date of issuance of the Note, except in connection with the imposition of a default rate of interest in accordance with the terms of the Note or the Purchase Agreement as they are in effect on the date hereof.

  (e) Each holder of the Note agrees that each holder of Senior Indebtedness may, at any time and from time to time hereafter without the consent of or notice to any holder of the Note, change the manner or time of payment or renew or alter any of the terms of such Senior Indebtedness, or amend in any manner any agreement, note, guaranty or other instrument evidencing or securing or otherwise relating to such Senior Indebtedness, provided that no holder of Senior Indebtedness shall (or shall not have the benefit of this Article IV to the extent it shall):

      (iii) add or modify any existing restrictions on the ability of Quantum, the Company, any guarantor or any subsidiary to repay the Note in addition to those set forth in such Senior Indebtedness as in effect on the date hereof (provided that any modification of any existing covenants or defaults, which has the effect of making them more restrictive, shall not be deemed, in and of itself, to be an additional restriction on the payment of the Note), or

      (iv) shorten the final scheduled maturity dates of any portion of such Senior Indebtedness, except to the extent permissible under such Senior Indebtedness as a consequence of a default thereunder, or

      (v) extend the final scheduled maturity dates of such Senior Indebtedness by more than one year beyond those set forth in such Senior Indebtedness in effect on the date hereof.

Each holder of the Note agrees that that, except as otherwise provided in Section 4.4 hereof, they shall have no right to undertake any Enforcement Action with respect to any of the Collateral, unless and until all of the holder(s) of Bank Indebtedness shall have been paid in full and the commitments thereunder and the commitments, if any, of the holders of the Senior Indebtedness to extend credit accommodations to Quantum or the Company have expired (and in any event subject to the limitations set forth in Section 4.4 hereof with respect to any Enforcement Action taken in connection with any Insolvency Proceeding).

  (b) Notwithstanding any Lien in the Collateral now or hereafter acquired by any holder of the Note, the holder(s) of the Bank Indebtedness may take possession of, sell, dispose of, and otherwise deal with all or any part of the Collateral, and may enforce any right or remedy available to it with respect to the Collateral, all without notice to or consent of the holder(s) of the Note except as specifically required by applicable law.

All proceeds received by the holder(s) of the Senior Indebtedness with respect to any Collateral shall be applied by the holder(s) of the Senior Indebtedness to the Senior Indebtedness secured by such Collateral in such order of application as the holder(s) of the Senior Indebtedness may choose.

  (d) Notwithstanding anything to the contrary in the Note or the Purchase Agreement, unless and until all of the holder(s) of the Senior Indebtedness shall have been paid in full and the commitments, if any, of the holders of the Bank Indebtedness to extend credit accommodations to Quantum or the Company have expired, no holder of

Section 4.3 Rights not Subordinated . The provisions of Article IV are for the purpose of defining the relative rights of the holders of Senior Indebtedness on the one hand and the holder of the Note on the other hand. As between the Company and the holder of the Note, nothing herein shall impair the Company’s obligation to the holder of the Note to pay to the holder both principal and interest in accordance with the terms of the Note. Except as provided in Article IV, as between the Company and the holder of the Note nothing herein shall be construed to prevent the holder of the Note from exercising all rights and remedies otherwise available under the Note or the Purchase Agreement or under applicable law upon the occurrence of an Event of Default. No provision of Article IV shall be deemed to subordinate, to any extent, any claim or right of any holder of the Note to any claim against the Company by any creditor or any other Person except to the extent expressly provided in Article IV.

Section 4.4 Enforcement and Bankruptcy . No objection, directly or indirectly, will be raised by any holder of the Note to any motion by the Agent for relief from automatic stay in any Insolvency Proceeding (including the automatic stay under 11 U.S.C. §362 or any successor statute) to foreclose on, sell or otherwise realize upon, or enforce rights and remedies with respect to, any Collateral or to prohibit use of cash that is part of the Collateral. Notwithstanding any other provision of this Agreement, if the Agent shall desire to permit the use by the Company of any of the Collateral that constitutes "cash collateral" under 11 U.S.C. §363 or any successor statute or similar statute, no objection, directly or indirectly, will be raised by any holder of the Note to any such use of cash collateral on the grounds of a failure to provide adequate protection for any Collateral, whether or not the Company shall have granted a lien or security interest of any kind on any Collateral in connection with the Agent’s permission to the Company to use cash collateral. No objection, directly or indirectly, will be raised by any holder of the Note to any sale, transfer or other disposition of any Collateral under 11 U.S.C. §363, or any successor statute, to which the Agent shall have consented, provided that such sale or other disposition shall be subject to a procedure to elicit higher and better bids, subject to full preservation without modification of the Agent’s rights that are provided under 11 U.S.C. §363(k). No holder of the Note shall, without express prior written consent of the Agent, file,

If the Agent files a plan or similar proposal in an Insolvency Proceeding, no holder of the Note shall elect application of 11 U.S.C. §1111(b)(2) (the "Election") without the Agent’s prior written consent. Without derogating from any of the foregoing, no holder of the Note generally shall take any action in connection with any Insolvency Proceeding that any such holder of the Note party would not otherwise be permitted to take under the Note or the Purchase Agreement.

ARTICLE VI

CONVERSION

Section 6.1 Conversion Procedure .

• (a) At any time and from time to time after November 24, 2007, and prior to the payment of this Note in full, the holder of this Note may convert all or any portion of the outstanding principal and/or accrued interest amount of this Note into a number of Common Shares (excluding any fractional share) determined by dividing the principal and/or accrued interest amount designated by such holder to be converted, by the Conversion Price then in effect; provided, that in no event shall any amount of accrued interest due on the Note be converted to Common Shares without the Company’s prior written consent, which it may withhold in its absolute discretion.

13

• (b) Except as otherwise expressly provided herein, each conversion of this Note shall be deemed to have been effected as of the close of business on the date on which this Note has been surrendered for conversion at the principal office of the Company. At such time as such conversion has been effected, the rights of the holder of this Note as such holder to the extent of the conversion shall cease, and the Person or Persons in whose name or names any certificate or certificates for Common Shares are to be issued upon such conversion shall be deemed to have become the holder or holders of record of the Common Shares represented thereby.

  (c) Notwithstanding any other provision hereof, if a conversion of any portion of this Note is to be made in connection with a registered public offering or a sale of the Company, the conversion of any portion of this Note may, at the election of the holder hereof, be conditioned upon the consummation of the public offering or the sale of the Company, in which case such conversion shall not be deemed to be effective until the consummation of such transaction.

  (d) As soon as possible after a conversion has been effected (but in any event within five (5) business days in the case of clause (i) below), the Company shall deliver to the converting holder:

  • • (i) a certificate or certificates representing the number of Common Shares (excluding any fractional share) issuable by reason of such conversion in such name or names and such denomination or denominations as the converting holder has specified;

      (ii) payment in an amount equal to the sum of all accrued interest with respect to the principal amount converted, which is not also being converted and has not been paid prior thereto, plus the amount payable under subsection (e) below; and

      (iii) a new Note representing any portion of the principal amount which was represented by the Note surrendered to the Company in connection with such conversion but which was not converted or which could not be converted because it would have required the issuance of a fractional share of Common Shares.

  (e) If any fractional share of Common Shares would, except for the provisions hereof, be deliverable upon conversion of this Note, the Company, in lieu of delivering such fractional share, shall in the event the conversion is being consummated in connection with repayment in full of the Note, pay in cash an amount equal to the Market Price of such fractional share as of the date of such conversion.

  (f) The issuance of certificates for Common Shares upon conversion of this Note shall be made without charge to the holder hereof for any issuance tax in respect thereof or other cost incurred by the Company in connection with such conversion and

14

• the related issuance of Common Shares. Upon conversion of this Note, the Company shall take all such actions as are necessary in order to insure that the Common Shares issuable with respect to such conversion shall be validly issued, fully paid and nonassessable.

  (g) The Company shall not close its books against the transfer of

Common Shares issued or issuable upon conversion of this Note in any manner which interferes with the timely conversion of this Note.

• (h) (i) Despite anything above to the contrary, the holder may not convert this Note into Common Shares under this Article 6 during the time period and to the extent that the shares of the Company’s Common Stock that the holder could acquire upon the conversion would cause holder’s (or its controlling Person’s) Beneficial Ownership of the Company’s Common Shares to exceed 4.99% of the Company’s outstanding Common Shares (including Common Shares, if any, that holder has acquired, or, by exercise by the Company of its rights to effect payment in kind under Article 9, that holder has the right to acquire, under Article 9). The holder will, at the request of the Company, from time to time, notify the Company of holder’s computation of holder’s or its controlling Person’s Beneficial Ownership.

The parties shall compute "Beneficial Ownership" of the Company’s Common Shares in accordance with Commission Rule 13d-3. Notwithstanding the foregoing, the limitation of 4.99% set forth in this paragraph shall not apply and a limitation of 9.99% shall, instead, apply on the same terms and conditions (i) during the period commencing with the Company’s provision of notice of an Organic Change pursuant to Section 6.5(b)(iii) and ending on the earlier of (a) the date holder gives notice to the Company that it waives irrevocably such temporary increase in its right to acquire Common Shares in respect of such Organic Change, (b) notice from the Company that it has determined in good faith that such Organic Change will not occur or (c) the date 30 days after such Organic Change; and (ii) at and after April 1, 2009. To the extent the holder requests conversion of principal or, with Company consent, accrued interest on the Note, and the Common Shares issuable upon such conversion would exceed the applicable limitation set forth in this Section 6.1(h)(i), then, first, the amount representing accrued interest, and, second (at the election of the Company, if prior to maturity), the amount representing principal, that, in either case, if converted would cause Common Shares in excess of such limitation to be issued, shall, instead, be paid in cash in the actual amounts outstanding (and not based on the value of Common Shares otherwise issuable).

• • • (ii) Unless the Company obtains the approval of its voting shareholders to such issuance in accordance with the rules of Nasdaq (in effect on the date hereof) with which the Company shall be required to comply (but only to the extent required thereby), the Company shall not issue Common Shares upon conversion of the Note, which when added to the number of shares of Common Shares previously issued by the Company (i) upon conversion of the Note and (ii) in payment of the Note pursuant to Article 9 below, would exceed the greater (i) 19.99% of the number of shares of the Company’s Common Shares which

15

• • • were issued and outstanding on the Closing Date or (ii) such number of Common Shares as shall have been expressly authorized by action of the Company’s shareholders in accordance with the Nasdaq marketplace rules (the "Maximum Issuance Amount"). In the event that the holder requests conversion of the Note such that would require the Company to issue shares of Common Shares in excess of the Maximum Issuance Amount, the Company shall honor such conversion request by (i) converting the Note into the number of shares of Common Shares stated in the conversion notice up to, but not in excess of, the Maximum Issuance Amount, and (ii) redeeming the number of shares of Common Shares stated in the conversion notice in excess of the Maximum Issuance Amount in cash at a price equal to the then-current fair market value (i.e., the closing bid price of the Company’s Common Stock on the Nasdaq System, or if not then traded on the Nasdaq System, then on the OTC Bulletin Board as reported by bigcharts.com, or if this service is discontinued, such other reporting service acceptable to the holder) on the date of redemption.

Section 6.2 Conversion Price . The initial Conversion Price shall be $2.36. To address dilution of the conversion rights granted under the Notes, the Conversion Price shall be subject to adjustment from time to time pursuant to Sections 6.3, 6.4 and 6.5.

Section 6.3 Adjustment of Conversion Price upon Issuance of Common Stock .

• (a) If and whenever on or after the date hereof, the Company issues or sells, or in accordance with this Section 6.3 is deemed to have issued or sold, any shares of Common Stock (including the issuance or sale of shares of Common Stock owned or held by or for the account of the Company) for a consideration per share (the "New Issuance Price") less than a price (the "Applicable Price") equal to $1.50 (the foregoing a "Dilutive Issuance"), then immediately after such Dilutive Issuance the Conversion Price then in effect shall be reduced to a price (calculated to the nearest one-hundredth of a cent) determined in accordance with the following formula:

CP ₂ = CP ₁ * (A + B) ÷ (A + C).

For purposes of the foregoing formula, the following definitions shall apply:

• • • " CP ₂ " shall mean the Conversion Price in effect immediately after such Dilutive Issuance;

      " CP ₁ " shall mean the Conversion Price in effect immediately prior to such Dilutive Issuance;

      " A " shall mean the number of shares of Common Stock outstanding immediately prior to such Dilutive Issuance;

      " B " shall mean the number of shares of Common Stock that would have been issued in such Dilutive Issuance if shares of Common Stock had been issued at a price per share equal to CP ₁ (determined by dividing the aggregate consideration received by the Company in respect of such issue by CP ₁ ); and

16

• • • " C " shall mean the number of shares of Common Stock issued or deemed to be issued in such Dilutive Issuance.

  (b) For purposes of determining the adjusted Conversion Price under this Section 6.3, the following shall be applicable:

  • • (i) Issuance of Rights or Options . In case at any time the Company shall in any manner grant (directly and not by assumption in a merger or otherwise) any warrants or other rights to subscribe for or to purchase, or any options for the purchase of, Common Stock or any stock or security convertible into or exchangeable for Common Stock (such warrants, rights or options being called "Options" and such convertible or exchangeable stock or securities being called "Convertible Securities") whether or not such Options or the right to convert or exchange any such Convertible Securities are immediately exercisable, and the price per share for which Common Stock is issuable upon the exercise of such Options or upon the conversion or exchange of such Convertible Securities (determined by dividing (i) the sum (which sum shall constitute the applicable consideration) of (x) the total amount, if any, received or receivable by the Company as consideration for the granting of such Options, plus (y) the aggregate amount of additional consideration payable to the Company upon the exercise of all such Options, plus (z), in the case of such Options which relate to Convertible Securities, the aggregate amount of additional consideration, if any, payable upon the issue or sale of such Convertible Securities and upon the conversion or exchange thereof, by (ii) the total maximum number of shares of Common Stock issuable upon the exercise of such Options or upon the conversion or exchange of all such Convertible Securities issuable upon the exercise of such Options) shall be less than the Conversion Price in effect immediately prior to the time of the granting of such Options, then the total number of shares of Common Stock issuable upon the exercise of such Options or upon conversion or exchange of the total amount of such Convertible Securities issuable upon the exercise of such Options shall be deemed to have been issued for such price per share as of the date of granting of such Options or the issuance of such Convertible Securities and thereafter shall be deemed to be outstanding for purposes of adjusting the Conversion Price. Except as otherwise provided in Section 6.3(b)(iii), no adjustment of the Conversion Price shall be made upon the actual issue of such Common Stock or of such Convertible Securities upon exercise of such Options or upon the actual issue of such Common Stock upon conversion or exchange of such Convertible Securities.

      (ii) Issuance of Convertible Securities . In case the Company shall in any manner issue (directly and not by assumption in a merger or otherwise) or sell any Convertible Securities, whether or not the rights to exchange or convert any such Convertible Securities are immediately exercisable, and the price per share

17

• • • for which Common Stock is issuable upon such conversion or exchange (determined by dividing (i) the sum (which sum shall constitute the applicable consideration) of (x) the total amount received or receivable by the Company as consideration for the issue or sale of such Convertible Securities, plus (y) the aggregate amount of additional consideration, if any, payable to the Company upon the conversion or exchange thereof, by (ii) the total number of shares of Common Stock issuable upon the conversion or exchange of all such Convertible Securities) shall be less than the Conversion Price in effect immediately prior to the time of such issue or sale, then the total maximum number of shares of Common Stock issuable upon conversion or exchange of all such Convertible Securities shall be deemed to have been issued for such price per share as of the date of the issue or sale of such Convertible Securities and thereafter shall be deemed to be outstanding for purposes of adjusting the Conversion Price, provided that (a) except as otherwise provided in Section 6.3(b)(iii), no adjustment of the Conversion Price shall be made upon the actual issuance of such Common Stock upon conversion or exchange of such Convertible Securities and (b) no further adjustment of the Conversion Price shall be made by reason of the issue or sale of Convertible Securities upon exercise of any Options to purchase any such Convertible Securities for which adjustments of the Conversion Price have been made pursuant to the other provisions of Section 6.3.

      (iii) Change in Option Price or Conversion Rate . Upon the happening of any of the following events, namely, if the purchase price provided for in any Option referred to in Section 6.3(b)(i) hereof, the additional consideration, if any, payable upon the conversion or exchange of any Convertible Securities referred to in Section 6.3(b)(i) or Section 6.3(b)(ii), or the rate at which Convertible Securities referred to in Section 6.3(b)(i) or Section 6.3(b)(ii) are convertible into or exchangeable for Common Stock shall change at any time (including, but not limited to, changes under or by reason of provisions designed to protect against dilution), the Conversion Price in effect at the time of such event shall forthwith be readjusted to the Conversion Price which would have been in effect at such time had such Options or Convertible Securities still outstanding provided for such changed purchase price, additional consideration or conversion rate, as the case may be, at the time initially granted, issued or sold. On the termination of any Option for which any adjustment was made pursuant to this Section 6.3 or any right to convert or exchange Convertible Securities for which any adjustment was made pursuant to this Section 6.3 (including without limitation upon the redemption or purchase for consideration of such Convertible Securities by the Company), the Conversion Price then in effect hereunder shall forthwith be changed to the Conversion Price which would have been in effect at the time of such termination had such Option or Convertible Securities, to the extent outstanding immediately prior to such termination, never been issued.

      (iv) Stock Dividends . Subject to the provisions of this Section 6.3, in case the Company shall declare a dividend or make any other distribution upon any stock of the Company (other than the Common Stock) payable in Common

18

• • • Stock, Options or Convertible Securities, then any Common Stock, Options or Convertible Securities, as the case may be, issuable in payment of such dividend or distribution shall be deemed to have been issued or sold without consideration.

      (v) Consideration for Stock . In case any shares of Common Stock, Options or Convertible Securities shall be issued or sold for cash, the consideration received therefor shall be deemed to be the net amount received by the Company therefor, after deduction therefrom of any expenses incurred or any underwriting commissions or concessions paid or allowed by the Company in connection therewith. In case any shares of Common Stock, Options or Convertible Securities shall be issued or sold for a consideration other than cash, the amount of the consideration other than cash received by the Company shall be deemed to be the fair value of such consideration as determined in good faith by the Board of Directors of the Company, after deduction of any expenses incurred or any underwriting commissions or concessions paid or allowed by the Company in connection therewith. In case any Options shall be issued in connection with the issue and sale of other securities of the Company, together comprising one integral transaction in which no specific consideration is allocated to such Options by the parties thereto, such Options shall be deemed to have been issued for such consideration as determined in good faith by the Board of Directors of the Company. If Common Stock, Options or Convertible Securities shall be issued or sold by the Company and, in connection therewith, other Options or Convertible Securities (the "Additional Rights") are issued, then the consideration received or deemed to be received by the Company shall be reduced by the fair market value of the Additional Rights (as determined using the Black-Scholes option pricing model or another method mutually agreed to by the Company and the Holder). The Board of Directors of the Company shall respond promptly, in writing, to an inquiry by the Holder as to the fair market value of the Additional Rights. In the event that the Board of Directors of the Company and the Holder are unable to agree upon the fair market value of the Additional Rights, the Company and the Holder shall jointly select an appraiser, who is experienced in such matters. The decision of such appraiser shall be final and conclusive, and the cost of such appraiser shall be borne evenly by the Company and the Holder.

      (vi) Record Date . In case the Company shall take a record of the holders of its Common Stock for the purpose of entitling them (i) to receive a dividend or other distribution payable in Common Stock, Options or Convertible Securities or (ii) to subscribe for or purchase Common Stock, Options or Convertible Securities, then such record date shall be deemed to be the date of the issue or sale of the shares of Common Stock deemed to have been issued or sold upon the declaration of such dividend or the making of such other distribution or the date of the granting of such right of subscription or purchase, as the case may be.

  (c) Notwithstanding the foregoing, no adjustment will be made under this Section 6.3 as a result of: (i) the issuance of securities upon the exercise or conversion of any

19

• Common Stock Equivalents issued by the Company prior to the date of this Note (but will apply to any amendments, modifications and reissuances thereof), (ii) the grant of options or warrants, or the issuance of additional securities, under any duly authorized company stock option, stock incentive plan, restricted stock plan or stock purchase plan in existence as of the date of this Note or (iii) the issuance of securities in connection with an acquisition or strategic transaction, the primary purposes of which, in the reasonable judgment of the Board of Directors, is not to raise additional capital.

Section 6.4 Subdivision or Combination of Common Stock . If the Company at any time subdivides (by any share split, share dividend or otherwise) one or more classes of its outstanding Common Shares into a greater number of shares, the Conversion Price in effect immediately prior to such subdivision shall be proportionately reduced, and if the Company at any time combines (by reverse share split or otherwise) one or more classes of its outstanding Common Shares into a smaller number of shares, the Conversion Price in effect immediately prior to such combination shall be proportionately increased.

Section 6.5 Reorganization, Reclassification, Consolidation, Merger or Sale . Any recapitalization, reorganization, reclassification, consolidation, merger, sale of all or substantially all of the Company’s assets or other transaction, which in each case is effected in such a manner that holders of Common Shares are entitled to receive (either directly or upon subsequent liquidation) stock, securities or assets with respect to or in exchange for Common Shares is referred to herein as an "Organic Change." Prior to the consummation of any Organic Change, the Company shall make lawful and adequate provision (in form and substance satisfactory to the holder of the Note) to insure that the holder of the Note shall thereafter have the right to acquire and receive, in lieu of or addition to (as the case may be) Common Shares immediately theretofore acquirable and receivable upon the conversion of the holder’s Note, such shares of stock, securities or assets as may be issued or payable with respect to or in exchange for the number of Common Shares immediately theretofore acquirable and receivable upon conversion of the holder’s Note had such Organic Change not taken place. In any such case, appropriate provision (in form and substance satisfactory to the holder of the Note) shall be made with respect to the holder’s rights and interests to insure that the provisions of this Article 6 shall thereafter be applicable in relation to any shares of stock, securities or assets thereafter deliverable upon the conversion of the Note (including, in the case of any such consolidation, merger or sale in which the successor entity or purchasing entity is other than the Company, an immediate adjustment of the Conversion Price to the value for the Common Shares reflected by the terms of such consolidation, merger or sale, and a corresponding immediate adjustment in the number of Common Shares acquirable and receivable upon conversion of the Note, if the value so reflected is less than the Conversion Price in effect immediately prior to such consolidation, merger or sale). The Company shall not effect any such consolidation, merger or sale, unless prior to the consummation thereof, the successor entity (if other than the Company) resulting from consolidation or merger or the entity purchasing such assets assumes by written instrument (in form reasonably satisfactory to the holder of the Note), the obligation to deliver to each the holder such shares of stock, securities or assets as, in accordance with the foregoing provisions, the holder may be entitled to acquire.

(a) Upon the date of the purchase and sale of the Bank Indebtedness, the holders of the Notes shall (i) pay to the Agent as the purchase price therefor the full amount of all the Bank Indebtedness then outstanding and unpaid (including principal, interest, fees and expenses, including reasonable attorneys’ fees and legal expenses), (ii) furnish cash collateral to the Agent in such amounts as the Agent determines are reasonably necessary to secure the Agent in connection with any issued and outstanding letters of credit provided by the Agent to Quantum or any subsidiary (but not in any event in an amount greater than 105% of the aggregate undrawn face amount of such letters of credit), and (iii) agree to reimburse the Agent for any out-of-pocket loss, cost, damage or expense (including reasonable attorneys’ fees and legal expenses) incurred within 90 days after the purchase and sale of the Bank Indebtedness and in connection any checks or other payments provisionally credited to the Bank Indebtedness, and/or as to which the Agent has not yet received final payment.

The Purchase Agreement contains terms governing the rights of the

holder of this Note, and all provisions of the Purchase Agreement are hereby incorporated herein in full by reference. Unless otherwise indicated herein, capitalized terms used in this Note have the same meanings set forth in the Purchase Agreement.

ARTICLE I

PAYMENT OF INTEREST; CONTINGENT INTEREST

Interest shall accrue on the Accreted Principal Amount at an annual rate equal to 11.50% (or, from and after any extension of the maturity date of this Note under Section 2.1 below, 9.50%) per annum, of which amount (a) 6.50% shall be payable in cash on each Interest Payment Date and (b) 5.0% (or, from and after any extension of the maturity date of this Note under Section 2.1 below, 3.0%) shall be payable by adding such interest to the Accreted Principal Amount on each Interest Payment Date (as defined below), and on the final maturity hereof (the "PIK Amount"). At any time, the outstanding principal amount of this Note, including all PIK Amounts and Default PIK Amounts (as defined below) added thereto through such time, is referred to in this Note as the "Accreted Principal Amount" (in each case computed on the basis of a 365/366-day year and the actual number of days elapsed in any year) on the unpaid principal amount of this Note outstanding from time to time, or (if less) at the highest rate then permitted under applicable law. The Company shall pay to the holder of this Note all accrued interest (including Contingent Additional Interest as described below) on the first day of each July and January (each, an "Interest Payment Date" ) and on the final maturity date of this Note. Any accrued cash interest which for any reason has not theretofore been paid shall increase the principal of the Note and be paid in full on the date on which the final principal payment on this Note is made (the "Default PIK Amounts"); provided that any such reason shall not affect or waive any Event of Default that arises due to the failure to make such payment in cash. Interest shall accrue on any principal payment due under this Note (including as to accrued interest added to the principal) until such time as payment therefore is actually delivered to the holder of this Note.

In the event that the Company fails by September 10, 2004 (the "Filing Deadline") to file the Registration Statement with the Commission, or fails by January 8, 2005 (the "Registration Deadline") to obtain effectiveness under the Securities Act and applicable state securities laws of the Registration Statement (as required by the terms of a Registration Rights Agreement between the Company and Purchaser of this date) registering all of the shares of Common Shares issuable as payment under or upon conversion of this Note as provided therein, then for each full month thereafter (prorated for partial months) that this failure continues (the "Failure Term"), and to the extent permitted by law, the Company shall pay in arrears in cash, with the next otherwise scheduled payment of interest pursuant to the above paragraph (or if the last scheduled interest payment has been made, then monthly on the same day of each succeeding month), additional interest (the "Contingent Additional Interest") equal to the greater of $5,000 or 0.5% of the outstanding principal balance on this Note as of the last day of the prior month. However, if the Failure Term runs for more than three months, the additional monthly cash interest payable thereafter shall increase, to the extent permitted by law, to the greater of $10,000 or 1% of the outstanding principal balance on this Note as of the last day of the prior month.

SUBORDINATION

Section 4.1 Debt Subordination . The indebtedness evidenced by the Note is subordinate and junior to any and all Indebtedness constituting Senior Indebtedness within the meaning of the Purchase Agreement ("Senior Indebtedness"). The Note is subordinate to Senior Indebtedness only to the extent and in the manner hereinafter set forth.

• (a) During the continuance of any Company Default and so long as any Company Default remains which has not been cured or waived by the holder of the Senior Indebtedness under which the Company Default arises, no payment of principal or interest shall be made on the Note, unless (and, if applicable, to the extent permitted by clause 4.1(b)(i), below) such payment is made in kind in the form of Common Shares as provided in Article 6 or Article 9; provided , that the Company may pay and the holder(s) of the Note may accept scheduled payments of interest upon the Note so long as (i) no Insolvency Proceeding has occurred, (ii) no Company Default that is a default in the payment of any principal, interest or any other amount on the Senior Indebtedness has occurred (each, a "Payment Default"), and (iiii)(A) the holder(s) of the Note have not received a written notice (a "Senior Non-Payment Default Notice") that a Company Default (other than a Payment Default) has occurred and is continuing or will occur as a

3

• result of or immediately following such payment, (B) each such Company Default has not been waived or cured in accordance with the terms of the Senior Documents, and (C) 180 days have not elapsed (each such 180 day period shall be referred to herein as a "Blockage Period") since the date the Senior Non-Payment Default Notice was received. Notwithstanding any provision in this Section 4.1(a) to the contrary (x) the Company shall not be prohibited from making, and the holder(s) of the Note shall not be prohibited from receiving, payments of interest upon the Note under clause (iii) of the preceding sentence for more than aggregate of 180 days within any period of 365 consecutive days; (y) no Company Default existing on the date any Senior Non-Payment Default Notice is given pursuant to this Section 4.1(a) shall, unless the same shall have ceased to exist for a period of at least 30 consecutive days, be used as the basis for any subsequent such notice; and (z) the failure of the Company to make any payment with respect to the Note by reason of the operation of this Section 4.1(a) shall not be construed as preventing the occurrence of a default under any loan agreement, credit agreement, security agreement, letter of credit, reimbursement agreement or other document or instrument evidencing or securing the Note.

  (b) If any cash payment is made on the Note at a time when the holders are not entitled to receive cash payments on the Note, the payment or distribution shall be delivered directly to the Agent for application against the Senior Indebtedness, unless and until all principal and interest on the Senior Indebtedness has been paid in full and the commitments, if any, of the holders of the Senior Indebtedness to extend credit accommodations to Quantum or the Company have expired, except that

  • • (i) no such delivery shall be made of stock or obligations issued by the Company or any corporation succeeding to the Company or acquiring its property and assets, pursuant to reorganization proceedings or dissolution or liquidation proceedings or upon any merger, consolidation, sale, lease, transfer or other disposal, if such stock or obligations are subordinate and junior at least to the extent provided hereunder to the payment of Senior Indebtedness to the extent then outstanding and to the payment of any stock or obligations which are concurrently therewith issued in exchange for Senior Indebtedness to the extent then outstanding, and

      (ii) if any holder of Senior Indebtedness receives any payment or distribution that, except for the provisions of this Section 4.1, would have been payable or deliverable with respect to the Note, the holders of the Note shall (after all principal and interest owing on such Senior Indebtedness has been paid in full and the commitments, if any, of the holders of the Senior Indebtedness to extend credit accommodations to Quantum or the Company have expired) be subrogated to the rights of such holders of such Senior Indebtedness against the Company.

  (c) Until all Senior Indebtedness has been paid in full and the commitments, if any, of the holders of the Senior Indebtedness to extend credit accommodations to Quantum or the Company have expired, the holders of the Note shall not, without the prior written consent of the Agent, take any Enforcement Action with respect to the

4

• Notes or any Collateral, until the earlier to occur of the following and in any event no earlier than ten (10) days after the Agent’s receipt of written notice from such holder of the Note of its intention to take such Enforcement Action (which notice may be issued during the 180 day period referred to in clause (iii) below with respect to an Enforcement Action that such holder of the Note has the right to commence upon the expiration of said 180 day period):

      (iii) the passage of 180 days from the delivery by the holder of a Note to the Agent of notice of an event of default under the Subordinated Documents if any default described therein shall not have been cured or waived within such period.

Notwithstanding the foregoing, but subject in all events to the provisions of Section 4.4, any holder of the Note may file proofs of claim against the Company in any Insolvency Proceeding involving the Company. Except for distributions of the type specified in Section 4(b)(i), any distributions or other proceeds of any Enforcement Action obtained by any holder of the Note shall in any event be held in trust by it for the benefit of the holders of the Senior Indebtedness and promptly paid or delivered to the Agent in the form received until all Senior Indebtedness has been paid in full and the commitments, if any, of the holders of the Senior Indebtedness to extend credit accommodations to Quantum or the Company have expired. Notwithstanding anything contained herein to the contrary, if following the acceleration of the Senior Indebtedness, such acceleration is rescinded (whether or not any existing Company Default has been cured or waived), then all Enforcement Actions taken by any holder of the Note shall likewise be rescinded if such Enforcement Action is based solely on clause (i) of this Section 4.1(c). Notwithstanding anything herein to the contrary, no provision herein shall prevent any holder of the Note from initiating a legal action or proceeding solely to the extent necessary to prevent the running of any applicable statute of limitation or similar restriction on claims.

• (d) Each holder of the Note waives notice of the creation of the Senior Indebtedness and notice of acceptance by the holder(s) of Senior Indebtedness of the subordination and other provisions set forth herein. The holder of the Note agrees that, so long as the Credit Agreement remains in effect, the subordination provisions of the Note and the Purchase Agreement may not be modified or amended without the prior written consent of the Agent and that any amendment or modification entered into without such consent shall be null and void and that it will not agree to:

  • • (i) any amendment of the Note or the Purchase Agreement that would shorten the due dates of any principal or interest payments upon the Note;

      (ii) any amendment of the covenants, events of default or other material provisions of the Note or the Purchase Agreement to make them more

5

      (iii) any amendment increasing the interest rate payable with respect to the Note to an interest rate that is 200 basis points more than the interest rate applicable to the Note on the date of issuance of the Note, except in connection with the imposition of a default rate of interest in accordance with the terms of the Note or the Purchase Agreement as they are in effect on the date hereof.

  (e) Each holder of the Note agrees that each holder of Senior Indebtedness may, at any time and from time to time hereafter without the consent of or notice to any holder of the Note, change the manner or time of payment or renew or alter any of the terms of such Senior Indebtedness, or amend in any manner any agreement, note, guaranty or other instrument evidencing or securing or otherwise relating to such Senior Indebtedness, provided that no holder of Senior Indebtedness shall (or shall not have the benefit of this Article IV to the extent it shall):

  • • (i) increase the principal amount of such Senior Indebtedness to an amount that would cause the sum of the total Senior Indebtedness to exceed $35,000,000,

      (ii) increase the interest rate margins or any fixed interest rate with respect to such Senior Indebtedness by more than 200 basis points above the margin currently in effect under such Senior Indebtedness, except in connection with the imposition of a default rate of interest in accordance with the terms of such Senior Indebtedness as in effect on the date hereof,

      (iii) add or modify any existing restrictions on the ability of Quantum, the Company, any guarantor or any subsidiary to repay the Note in addition to those set forth in such Senior Indebtedness as in effect on the date hereof (provided that any modification of any existing covenants or defaults, which has the effect of making them more restrictive, shall not be deemed, in and of itself, to be an additional restriction on the payment of the Note), or

      (iv) shorten the final scheduled maturity dates of any portion of such Senior Indebtedness, except to the extent permissible under such Senior Indebtedness as a consequence of a default thereunder, or

      (v) extend the final scheduled maturity dates of such Senior Indebtedness by more than one year beyond those set forth in such Senior Indebtedness in effect on the date hereof.

  (f) Each holder of the Note consents and agrees that all Senior Indebtedness shall be deemed to have been made, incurred and/or continued in reliance upon the subordination provisions set forth herein and in the Purchase Agreement and each holder

6

• of any Senior Indebtedness is an intended third party beneficiary of the subordination and other provisions of this Article 4. This Article IV shall bind and enure to the benefit of all holders of the Note and the Senior Indebtedness existing on the date of the Note or arising after such date (and all holders of Senior Indebtedness, by extending such Senior Indebtedness, shall be deemed to be bound by this Article IV)

  (g) Each holder of the Note agrees that it shall not accept any prepayment of the Note until the Senior Indebtedness has been paid in full and the commitments, if any, of the holders of the Senior Indebtedness to extend credit accommodations to Quantum or the Company have expired, unless (and, if applicable, to the extent permitted by clause 4.1(b)(i) above) such payment is made in kind in the form of Common Shares as provided in Article 6 or Article 9).

  (h) Subject to Section 4.1(e) hereof, all rights and interest of the holders of the Senior Indebtedness hereunder, and all agreements and obligations of the holder of the Note hereunder, shall remain in full force and effect irrespective of:

Each holder of the Note agrees that that, except as otherwise provided in Section 4.4 hereof, they shall have no right to undertake any Enforcement Action with respect to any of the Collateral, unless and until all of the holder(s) of Bank Indebtedness shall have been paid in full and the commitments thereunder and the commitments, if any, of the holders of the Senior Indebtedness to extend credit accommodations to Quantum or the Company have expired (and in any event subject to the limitations set forth in Section 4.4 hereof with respect to any Enforcement Action taken in connection with any Insolvency Proceeding).

  (b) Notwithstanding any Lien in the Collateral now or hereafter acquired by any holder of the Note, the holder(s) of the Bank Indebtedness may take possession of, sell, dispose of, and otherwise deal with all or any part of the Collateral, and may enforce any right or remedy available to it with respect to the Collateral, all without notice to or consent of the holder(s) of the Note except as specifically required by applicable law.

All proceeds received by the holder(s) of the Senior Indebtedness with respect to any Collateral shall be applied by the holder(s) of the Senior Indebtedness to the Senior Indebtedness secured by such Collateral in such order of application as the holder(s) of the Senior Indebtedness may choose.

  (d) Notwithstanding anything to the contrary in the Note or the Purchase Agreement, unless and until all of the holder(s) of the Senior Indebtedness shall have been paid in full and the commitments, if any, of the holders of the Bank Indebtedness to extend credit accommodations to Quantum or the Company have expired, no holder of

Section 4.3 Rights not Subordinated . The provisions of Article IV are for the purpose of defining the relative rights of the holders of Senior Indebtedness on the one hand and the holder of the Note on the other hand. As between the Company and the holder of the Note, nothing herein shall impair the Company’s obligation to the holder of the Note to pay to the holder both principal and interest in accordance with the terms of the Note. Except as provided in Article IV, as between the Company and the holder of the Note nothing herein shall be construed to prevent the holder of the Note from exercising all rights and remedies otherwise available under the Note or the Purchase Agreement or under applicable law upon the occurrence of an Event of Default. No provision of Article IV shall be deemed to subordinate, to any extent, any claim or right of any holder of the Note to any claim against the Company by any creditor or any other Person except to the extent expressly provided in Article IV.

Section 4.4 Enforcement and Bankruptcy . No objection, directly or indirectly, will be raised by any holder of the Note to any motion by the Agent for relief from automatic stay in any Insolvency Proceeding (including the automatic stay under 11 U.S.C. §362 or any successor statute) to foreclose on, sell or otherwise realize upon, or enforce rights and remedies with respect to, any Collateral or to prohibit use of cash that is part of the Collateral. Notwithstanding any other provision of this Agreement, if the Agent shall desire to permit the use by the Company of any of the Collateral that constitutes "cash collateral" under 11 U.S.C. §363 or any successor statute or similar statute, no objection, directly or indirectly, will be raised by any holder of the Note to any such use of cash collateral on the grounds of a failure to provide adequate protection for any Collateral, whether or not the Company shall have granted a lien or security interest of any kind on any Collateral in connection with the Agent’s permission to the Company to use cash collateral. No objection, directly or indirectly, will be raised by any holder of the Note to any sale, transfer or other disposition of any Collateral under 11 U.S.C. §363, or any successor statute, to which the Agent shall have consented, provided that such sale or other disposition shall be subject to a procedure to elicit higher and better bids, subject to full preservation without modification of the Agent’s rights that are provided under 11 U.S.C. §363(k). No holder of the Note shall, without express prior written consent of the Agent, file,

9

join in, support directly or indirectly, vote to accept, or fail to object to, any plan of reorganization that provides for the Senior Indebtedness to be impaired (as defined under 11 U.S.C. §1124), whether or not any such holder of the Note shall have made the Election (defined in the next sentence). If the Agent files a plan or similar proposal in an Insolvency Proceeding, no holder of the Note shall elect application of 11 U.S.C. §1111(b)(2) (the "Election") without the Agent’s prior written consent. Without derogating from any of the foregoing, no holder of the Note generally shall take any action in connection with any Insolvency Proceeding that any such holder of the Note party would not otherwise be permitted to take under the Note or the Purchase Agreement.

Section 4.5 Defined Terms . For purposes of this Article IV, the following terms shall have the meanings set forth below:

ARTICLE VI

CONVERSION

Section 6.1 Conversion Procedure .

• (a) At any time and from time to time after November 24, 2007, and prior to the payment of this Note in full, the holder of this Note may convert all or any portion of the outstanding principal and/or accrued interest amount of this Note into a number of Common Shares (excluding any fractional share) determined by dividing the principal and/or accrued interest amount designated by such holder to be converted, by the Conversion Price then in effect; provided, that in no event shall any amount of accrued interest due on the Note be converted to Common Shares without the Company’s prior written consent, which it may withhold in its absolute discretion.

13

• (b) Except as otherwise expressly provided herein, each conversion of this Note shall be deemed to have been effected as of the close of business on the date on which this Note has been surrendered for conversion at the principal office of the Company. At such time as such conversion has been effected, the rights of the holder of this Note as such holder to the extent of the conversion shall cease, and the Person or Persons in whose name or names any certificate or certificates for Common Shares are to be issued upon such conversion shall be deemed to have become the holder or holders of record of the Common Shares represented thereby.

  (c) Notwithstanding any other provision hereof, if a conversion of any portion of this Note is to be made in connection with a registered public offering or a sale of the Company, the conversion of any portion of this Note may, at the election of the holder hereof, be conditioned upon the consummation of the public offering or the sale of the Company, in which case such conversion shall not be deemed to be effective until the consummation of such transaction.

  (d) As soon as possible after a conversion has been effected (but in any event within five (5) business days in the case of clause (i) below), the Company shall deliver to the converting holder:

  • • (i) a certificate or certificates representing the number of Common Shares (excluding any fractional share) issuable by reason of such conversion in such name or names and such denomination or denominations as the converting holder has specified;

      (ii) payment in an amount equal to the sum of all accrued interest with respect to the principal amount converted, which is not also being converted and has not been paid prior thereto, plus the amount payable under subsection (e) below; and

      (iii) a new Note representing any portion of the principal amount which was represented by the Note surrendered to the Company in connection with such conversion but which was not converted or which could not be converted because it would have required the issuance of a fractional share of Common Shares.

  (e) If any fractional share of Common Shares would, except for the provisions hereof, be deliverable upon conversion of this Note, the Company, in lieu of delivering such fractional share, shall in the event the conversion is being consummated in connection with repayment in full of the Note, pay in cash an amount equal to the Market Price of such fractional share as of the date of such conversion.

  (f) The issuance of certificates for Common Shares upon conversion of this Note shall be made without charge to the holder hereof for any issuance tax in respect thereof or other cost incurred by the Company in connection with such conversion and

14

• the related issuance of Common Shares. Upon conversion of this Note, the Company shall take all such actions as are necessary in order to insure that the Common Shares issuable with respect to such conversion shall be validly issued,
