The following constitute the provisions of the Employee Stock Purchase Plan (herein called the "Plan") of Quantum Corporation (herein called the "Company").

1. Purpose. The purpose of the Plan is to provide Employees of the Company and its Designated Subsidiaries with an opportunity to purchase Common Stock of the Company through accumulated payroll deductions or other contributions. It is the intention of the Company to have the Plan qualify as an "Employee Stock Purchase Plan" under Section 423 of the Code, although the Company makes no undertaking or representation to maintain such qualification. The provisions of the Plan shall, accordingly, be construed so as to extend and limit participation in a manner consistent with the requirements of that section of the Code. In addition, this Plan document authorizes the purchase of Common Stock under a Non-423(b) Component, pursuant to rules, procedures or sub-plans adopted by the Board or a committee appointed by the Board and designed to achieve tax, securities law or other objectives.

The Board or a committee appointed by the Board shall have the discretion to determine what constitutes Compensation for Employees outside of the United States.

(g) "Continuous Status as an Employee" shall mean the absence of any interruption or termination of service as an Employee. Continuous Status as an Employee shall not be considered interrupted in the case of: (i) a leave of absence agreed to in writing by the Company, provided that such leave is for a period of not more than 90 days or re-employment upon the expiration of such leave is guaranteed by contract or statute; or (ii) notification by the Company of termination under a reduction-in-force. Termination in the case of a reduction-in-force shall be considered to have occurred at the end of the employee's continuation period.

(i) "Employee" means any person, including an officer, who is employed by the Company or one of its Designated Subsidiaries. The Board or a committee appointed by the Board, in its discretion, from time to time may, prior to an Enrollment Date for all options to be granted on such Enrollment Date, determine (on a uniform and nondiscriminatory basis) that the definition of Employee will or will not include an individual if he or she: (i) has not completed at least two (2) years of service since his or her last hire date (or such lesser period of time as may be determined by the Board or a committee appointed by the Board in its discretion), (ii)  is an officer or other manager, or (iii) is a highly compensated employee under Section 414(q) of the Code.

(m) "Non-423(b) Component" means the grant of an option under the Plan which is not intended to meet the requirements set forth in Section 423(b) of the Code, as amended.

(n) "Offering Period" shall mean a period commencing on an Enrollment Date and ending on the Exercise Date, approximately six (6) months later, or as otherwise set forth in Section 4 hereof.

3. Eligibility

(a) Any Employee (as defined in Section 2) who shall be employed by the Company or one of its Designated Subsidiaries on the date his or her participation in the Plan is effective shall be eligible to participate in the Plan, unless the Company, in its own discretion, decides that such participation would infringe any U.S. or foreign law, rules or regulations.

(b) Any provisions of the Plan to the contrary notwithstanding, no Employee shall be granted an option under the Plan (i) if, immediately, after the grant, such Employee (or any other person whose stock would be attributed to such Employee pursuant to Section 424(d) of the Code) would own shares and/or hold outstanding options to purchase stock possessing five percent (5%) or more of the total combined voting power or value of all classes of stock of the Company or of any Subsidiary, or (ii) which permits his or her rights to purchase shares under all employee stock purchase plans (as defined in Section 423 of the Code) of the Company and its Subsidiaries to accrue at a rate which exceeds Twenty-Five Thousand Dollars (US$25,000) of the fair market value of the shares (determined at the time such option is granted) for each calendar year in which such option is outstanding at any time.

(c) No employee of the Company or a Designated Subsidiary shall be eligible to participate in the Non-423(b) Component of the Plan if he or she is an officer or director of the Company subject to the requirements of Section 16 of the U.S. Securities Exchange Act of 1934, as amended (the "Act").

4. Offering Dates. The Plan shall be implemented by consecutive Offering Periods with a new Offering Period commencing on an Enrollment Date, and shall continue thereafter until terminated in accordance with Section 19 hereof. The Board or a committee appointed by the Board shall have the power to change the duration of Offering Periods with respect to future offerings without stockholder approval if such change is announced at least fifteen (15) days prior to the scheduled beginning of the first Offering Period to be affected. In no event shall the duration of an Offering Period exceed nine (9) months. Notwithstanding the foregoing, no offers hereunder shall be made until compliance with all applicable securities law has been obtained.

5. Participation.

(a) An eligible Employee may become a participant in the Plan by completing a subscription agreement authorizing payroll deductions on the form provided by the Company and filing it with the Company prior to the applicable Enrollment Date, unless a later time for filing the subscription agreement is set by the Board or a committee appointed by the Board for all eligible Employees with respect to a given Offering Period. The Company, in its discretion, may decide that an Employee may submit contributions to the Plan by means other than payroll deductions.

(b) Payroll deductions to the Plan for a participant shall commence on the first payroll following the Enrollment Date and shall end on the last payroll date in the Offering Period to which such authorization is applicable, unless sooner terminated by the participant as provided in Section 10. If participants are permitted or required to contribute to the Plan by other means, the Company, in its discretion, will determine the procedure for providing the contributions prior to the Exercise Date.

6. Payroll Deductions/Contributions.

(a) At the time a participant files his or her subscription agreement, he or she shall elect to contribute to the Plan (in the form of payroll deductions or otherwise) on each payday during the Offering Period at a rate not exceeding ten percent (10%) of the Compensation which he or she received on such payday, and the aggregate of such payroll deductions pursuant to the Plan during the Offering Period shall not exceed ten percent (10%) of his or her aggregate Compensation during said Offering Period. A participant's subscription agreement shall remain in effect for successive Offering Periods unless terminated as provided in Section 10 hereof.

(b) All contributions made for a participant shall be credited to his or her account under the Plan.

(c) A participant may discontinue participation in the Plan as provided in Section 10, or may change the rate of payroll deductions or other contributions by submitting written notice to the Company in the form and manner prescribed by the Board or a committee appointed by the Board (or its designee) authorizing a change in the participant's payroll deduction or contribution rate. The change rate shall be effective (i) in the case of a decrease in rate, with the first payroll period following the Company's receipt of the notice of rate change, and (ii) in the case of an increase in rate at the beginning of the next Offering Period following the Company's receipt of the notice of rate change. If a participant has not followed the procedures prescribed by the Board or a committee appointed by the Board (or its designee) to change the rate of payroll deductions or other contributions, the rate of his or her payroll deductions or other contributions will continue at the originally elected rate throughout the Offering Period and future Offering Periods (unless terminated as provided in Section 10). The Board or a committee appointed by the Board may, in its sole discretion, limit the nature and/or number of payroll deduction or contribution rate changes that may be made by participants during any Offering Period.

7. Grant of Option.

(a) On the Enrollment Date of each Offering Period, each eligible Employee participating in such Offering Period shall be granted an option to purchase on the Exercise Date during such Offering Period up to a number of shares of the Company's Common Stock determined by dividing such Employee's contributions to the Plan accumulated during the Offering Period ending on such Exercise Date by the lower of (i) eighty-five percent (85%) of the Fair Market Value of a share of the Company's Common Stock on the Enrollment Date, or (ii) eighty-five (85%) of the Fair Market Value of a share of the Company's Common Stock on the Exercise Date; provided that in no event shall an Employee be permitted to purchase in one calendar year more than a number of shares determined by dividing US$25,000 by the Fair Market Value of a share of the Company's Common Stock (determined at the time such option is granted), and provided further that such purchase shall be subject to the limitations set forth in Sections 3(b) and 12 hereof. The option shall be automatically exercised on the Exercise Date during the Offering Period, unless the participant has withdrawn pursuant to Section 10, and shall expire on the last day of the Offering Period.

(b) The purchase price per share of the shares offered in a given offering Period shall be the lower of: (i) 85% of the Fair Market Value of a share of the Common Stock of the Company on the Enrollment Date; or (ii) 85% of the Fair Market Value of a share of the Common Stock of the Company on the Exercise Date (such price, the "Purchase Price").

(c) Notwithstanding the foregoing, to the extent necessary to comply with Section 423(b)(8) of the Code and Section 3(b) herein, a participant's contributions may be decreased to 0% at such time during any Offering Period which is scheduled to end during the current calendar year that the aggregate of all contributions accumulated with respect to such Offering Period and any other Offering Period ending within the same calendar year equal $21,250. Contributions shall recommence at the rate provided in such participant's subscription scheduled to end in the following calendar year, unless terminated by the participant as provided in Section 10.

(d) If the Board or a committee appointed by the Board determines, in its sole discretion, that the exercise of an option or the disposition of Common Stock issued under the Plan will result in tax liability for which the Company or a Designated Subsidiary will have an obligation to withhold, the participant must make adequate provision for the payment of such federal, state, local and foreign income, social insurance, employment and any other applicable taxes. At any time, the Company or the Designated Subsidiary may, but will not be obligated to, withhold from the participant's compensation the amount necessary for the Company or the Designated Subsidiary to meet applicable withholding obligations, including any withholding required to make available to the Company or the Designated Subsidiary any tax deductions or benefits attributable to the sale or early disposition of Common Stock by the eligible Employee.

8. Exercise of Option. The participant's option for the purchase of shares will be exercised automatically on each Exercise Date of each Offering Period and the maximum number of full shares subject to option will be purchased for such participant at the applicable Purchase Price with the accumulated payroll deductions or other contributions in his or her account unless prior to such Exercise Date the participant has withdrawn from the Offering Period as provided in Section 10. During a participant's lifetime, a participant's option to purchase shares hereunder is exercisable only by the participant. No fractional shares shall be purchased; any payroll deductions or other contributions accumulated in a participant's account which are not sufficient to purchase a full share, or which would cause the limitations under Sections 3 or 7 hereof to be exceeded, shall be returned to the participant after the Exercise Date.

9. Delivery. As promptly as practicable after each Exercise Date, the Company shall arrange the delivery to each participant, as appropriate, the shares of Common Stock purchased upon exercise of the option. The Company may permit or require that shares be deposited directly with a broker designated by the Company or to a designated agent of the Company, and the Company may utilize electronic or automated methods of share transfer. The Company may require that shares be retained with such broker or agent for a designated period of time and/or may establish other procedures to permit tracking of disqualifying dispositions of such shares. No participant will have any voting, dividend, or other stockholder rights with respect to shares of Common Stock subject to any option granted under the Plan until such shares have been purchased and delivered to the participant as provided in this Section 9.

10. Withdrawal; Termination of Employment.

(a) A participant may withdraw all but not less than all the contributions credited to his or her account under the Plan at any time prior to the end of the Offering Period by giving written notice to the Company in the form and manner prescribed by the Board or a committee appointed by the Board for such purpose. All of the participant's contributions credited to his or her account will be paid to him or her promptly after receipt of his or her notice of withdrawal and his or her option for the current Offering Period will be automatically terminated, and no further contributions for the purchase of shares will be made during the Offering Period. If a participant withdraws from an Offering Period, contributions may not resume at the beginning of the succeeding Offering Period unless the participant delivers to the Company a new subscription agreement.

(b) Upon termination of the participant's employment prior to the end of the Offering Period for any reason, including retirement or death, the contributions credited to his or her account will be returned to him or, in the case of his or her death, to the person or persons entitled thereto under Section 14, and his or her option will be automatically terminated; provided that if an Employee shall take a leave of absence approved by the Company in accordance with Section 2(g) of this Plan during an Offering Period in which the Employee is a participant, the participant will be deemed to have his or her contributions reduced to 0% during such leave of absence, but he or she shall continue to be a participant in the applicable Offering Period and upon his or her return to employment with the Company shall be eligible to participate fully in any remaining portion of the applicable Offering Period. If the participant fails to return to employment with the Company at the end of such authorized leave of absence, or if his or her employment is otherwise terminated earlier, he or she shall be deemed to have withdrawn from participation in the Plan.

(c) A participant's withdrawal from an Offering Period will not have any effect upon his or her eligibility to participate in any similar plan which may hereafter be adopted by the Company or in succeeding Offering Periods.

11. Interest. No interest shall accrue on the contributions of a participant in the Plan, unless required by applicable law.

12. Stock.

(a) The maximum number of shares of the Company's Common Stock which shall be made available for sale under the Plan shall be 13,734,637, subject to adjustment upon changes in capitalization of the Company as provided in Section 18. If the total number of shares which would otherwise be subject to options granted pursuant to Section 7(a) hereof at the beginning of an Offering Period exceeds the number of shares then available under the Plan (after deduction of all shares for which options have been exercised or are then outstanding), the Company shall make a pro rata allocation of the shares remaining available for option grant in as uniform a manner as shall be practicable and as it shall determine to be equitable. In such event, the Company shall give written notice of such reduction of the number of shares subject to the option to each Employee affected thereby and shall similarly reduce the rate of contributions, if necessary.

(b) Until the shares are issued (as evidenced by the appropriate entry on the books of the Company or of a duly authorized transfer agent of the Company), a participant will only have the rights of an unsecured creditor with respect to such shares, and no right to vote or receive dividends or any other rights as a stockholder will exist with respect to such shares.

(c) Shares to be delivered to a participant under the Plan will be registered in the name of the participant or in the name of the participant and his or her spouse, or as otherwise directed by the participant.

13. Administration. The Plan shall be administered by the Board of Directors of the Company or a committee appointed by the Board. The administration, interpretation or application of the Plan by the Board or its committee shall be final, conclusive and binding upon all participants. Members of the Board who are eligible Employees are permitted to participate in the Plan, provided that:

(a) Members of the Board who are eligible to participate in the Plan may not vote on any matter affecting the administration of the Plan or the grant of any option pursuant to the Plan.

(b) If a committee is established by the Board to administer the Plan, no member of the Board who is eligible to participate in the Plan may be a member of the committee.

Notwithstanding any provision to the contrary in this Plan, the Board or a committee appointed by the Board may adopt rules, procedures or sub-plans relating to the operation and administration of the Plan to accommodate the specific requirements of local laws and procedures for jurisdictions outside of the United States. Without limiting the generality of the foregoing, the Board or a committee appointed by the Board is specifically authorized to adopt rules, procedures or sub-plans regarding eligibility to participate, the definition of Compensation, handling of payroll deductions, making of contributions to the Plan (including, without limitation, in forms other than payroll deductions), establishment of bank or trust accounts to hold payroll deductions, payment of interest, conversion of local currency, obligations to pay payroll tax, determination of beneficiary designation requirements, withholding procedures and handling of stock certificates which vary with local requirements.

14. Designation of Beneficiary.

(a) Unless otherwise determined by the Company, a participant may file a written designation of a beneficiary who is to receive any shares and cash, if any, from the participant's account under the Plan in the event of such participant's death subsequent to the end of the Offering Period but prior to delivery to him of such shares and cash. In addition, unless otherwise determined by the Company, a participant may file a written designation of a beneficiary who is to receive any cash from the participant's account under the Plan in the event of such participant's death prior to the end of the Offering Period.

(b) Unless otherwise determined by the Company, such designation of beneficiary may be changed by the participant at any time by written notice to the Company in the form and manner prescribed by the Board or a committee appointed by the Board for such purpose. In the event of the death of a participant and in the absence of a beneficiary validly designated under the Plan who is living at the time of such participant's death, the Company shall deliver such shares and/or cash to the executor or administrator of the estate of the participant, or if no such executor or administrator has been appointed (to the knowledge of the Company), the Company, in its discretion, may deliver such shares and/or cash to the spouse or to any one or more dependents or relatives of the participant, or if no spouse, dependent or relative is known to the Company, then to such other person as the Company may designate or determine to be the appropriate recipients of the shares and/or cash under applicable law.

(c) All beneficiary designations will be in such form and manner as the Board or a committee appointed by the Board may prescribe from time to time.

15. Transferability. Neither contributions credited to a participant's account nor any rights with regard to the exercise of an option or to receive shares under the Plan may be assigned, transferred, pledged or otherwise disposed of in any way (other than by will, the laws of descent and distribution or as provided in Section 14 hereof) by the participant. Any such attempt at assignment, transfer, pledge or other disposition shall be without effect, except that the Company may treat such act as an election to withdraw funds in accordance with Section 10.

16. Use of Funds. All contributions received or held by the Company under the Plan may be used by the Company for any corporate purpose, and the Company shall not be obligated to segregate such contributions, unless required by applicable law. Until shares of Common Stock are issued, participants will only have the rights of an unsecured creditor with respect to such shares.

17. Reports. Individual accounts will be maintained for each participant in the Plan. Statements of account will be given to participating Employees at least annually as promptly as practically feasible following an Exercise Date, which statements will set forth the amounts of contributions, the per share Purchase Price, the number of shares purchased and the remaining cash balance, if any.

18. Adjustments Upon Changes in Capitalization. In the event that any dividend or other distribution (whether in the form of cash, shares of Common Stock, other securities, or other property), recapitalization, stock split, reverse stock split, reorganization, merger, consolidation, split-up, spin-off, combination, repurchase, or exchange of shares of Common Stock or other securities of the Company, or other change in the corporate structure of the Company that affects the shares of Common Stock, then the Board or a committee appointed by the Board shall, in such manner as it may deem equitable, adjust the number and class of shares of Common Stock (or other securities, property or cash) that may be delivered under the Plan, and the number, class, and price of shares of Common Stock subject to any option under the Plan which has not yet been exercised, as determined by the Board or a committee appointed by the Board (in its sole discretion) to be appropriate in order to prevent dilution or enlargement of the benefits or potential benefits intended to be made available under the Plan.

19. Amendment or Termination.

(a) The Board of Directors of the Company may at any time and for any reason terminate or amend the Plan. Except as provided in Section 18 hereof, no such termination can affect options previously granted, provided that an Offering Period may be terminated by the Board of Directors or a committee appointed by the Board on an Exercise Date if the Board or its committee, as applicable, determines that the termination of the Offering Period or the Plan is in the best interests of the Company and its shareholders. Except as provided in Section 18 and this Section 19 hereof, no amendment may make any change in any option theretofore granted which adversely affects the rights of any participant. To the extent necessary to comply with Section 423 of the Code (or any successor rule or provision or any other applicable law, regulation or stock exchange rule), the Company shall obtain shareholder approval in such a manner and to such a degree as required.

(b) Without shareholder consent and without regard to whether any participant rights may be considered to have been "adversely affected," the Board (or its committee) shall be entitled to change the Offering Periods, limit the frequency and/or number of changes in the amount withheld during an Offering Period, establish the exchange ratio applicable to amounts withheld in a currency other than U.S. dollars, permit payroll withholding or contributing to the Plan in excess of the amount designated by a participant in order to adjust for delays or mistakes in the Company's processing of properly completed withholding elections, establish reasonable waiting and adjustment periods and/or accounting and crediting procedures to ensure that amounts applied toward the purchase of Common Stock for each participant properly correspond with amounts withheld from the participant's Compensation, and establish such other limitations or procedures as the Board (or its committee) determines in its sole discretion advisable which are consistent with the Plan.

(c) Notwithstanding anything to the contrary in this Plan, in the event the Board (or its committee) determines that the ongoing operation of the Plan may result in unfavorable financial accounting consequences, the Board (or its committee) may, in its discretion and, to the extent necessary or desirable, modify or amend the Plan to reduce or eliminate such accounting consequence including, but not limited to:

Such modifications or amendments shall not require stockholder approval or the consent of any Plan participants.

20. Notices. All notices or other communications by a participant to the Company under or in connection with the Plan shall be deemed to have been duly given when received in the form specified by the Company at the location, or by the person, designated by the Company for the receipt thereof.

21. Stockholder Approval. If required by Section 19, any amendment to the Plan shall be subject to approval by the stockholders of the Company within twelve months before or after the date such amendment is adopted. If such stockholder approval is obtained at a duly held stockholders' meeting, it may be obtained by the affirmative vote of the holders of a majority of the outstanding shares of the Company present or represented and entitled to vote thereon, which approval shall be:

(a) solicited substantially in accordance with Section 14(a) of the Act and the rules and regulations promulgated thereunder, or (2) solicited after the Company has furnished in writing to the holders entitled to vote substantially the same information concerning the Plan as that which would be required by the rules and regulations in effect under Section 14(a) of the Act at the time such information is furnished; and

(b) obtained at or prior to the first annual meeting of stockholders held subsequent to the later of (i) the first registration of Common Stock under Section 12 of the Act, or (ii) the acquisition of an equity security for which exemption is claimed.

In the case of approval by written consent, it must be obtained in accordance with applicable state law.

22. Conditions Upon Issuance of Shares. Shares shall not be issued with respect to an option unless the exercise of such option and the issuance and delivery of such shares pursuant thereto shall comply with all applicable provisions of law, domestic or foreign, including, without limitation, the U.S. Securities Act of 1933, as amended, the Act, the rules and regulations promulgated thereunder, and the requirements of any stock exchange upon which the shares may then be listed, and shall be further subject to the approval of counsel for the Company with respect to such compliance.

As a condition to the exercise of an option, the Company may require the person exercising such option to represent and warrant at the time of any such exercise that the shares are being purchased only for investment and without any present intention to sell or distribute such shares if, in the opinion of counsel for the Company, such a representation is required by any of the aforementioned applicable provisions of law.

23. Dissolution or Liquidation. In the event of the proposed dissolution or liquidation of the Company, the Offering Period then in progress shall be shortened by setting a new Exercise Date (the "New Exercise Date"), and shall terminate immediately prior to the consummation of such proposed dissolution or liquidation, unless provided otherwise by the Board or a committee appointed by the Board.  The New Exercise Date shall be before the date of the Company's proposed dissolution or liquidation.  The Board or a committee appointed by the Board shall notify each participant in writing, at least ten (10) business days prior to the New Exercise Date, that the Exercise Date for the participant's option has been changed to the New Exercise Date and that the participant's option shall be exercised automatically on the New Exercise Date, unless prior to such date the participant has withdrawn from the Offering Period as provided in Section 10 hereof.

24. Merger or Asset Sale.  In the event of a merger of the Company with or into another corporation or the sale of substantially all of the assets of the Company, each outstanding option shall be assumed or an equivalent option substituted by the successor corporation or a Parent or Subsidiary of the successor corporation.  In the event that the successor corporation refuses to assume or substitute for the option, the Offering Period then in progress shall be shortened by setting a New Exercise Date and such Offering Period shall end on the New Exercise Date.  The New Exercise Date shall be before the date of the Company's proposed merger or asset sale. The Board or a committee appointed by the Board shall notify each participant in writing, at least ten (10) business days prior to the New Exercise Date, that the Exercise Date for the participant's option has been changed to the New Exercise Date and that the participant's option shall be exercised automatically on the New Exercise Date, unless prior to such date the participant has withdrawn from the Offering Period as provided in Section 10 hereof.

25. Code Section 409A. The Code Section 423(b) Plan is exempt from the application of Section 409A of the Code. The Non-423(b) Component is intended to be exempt from Section 409A of the Code under the short-term deferral exception and any ambiguities shall be construed and interpreted in accordance with such intent. In the case of a participant who would otherwise be subject to Section 409A of the Code, to the extent an option to purchase shares of Common Stock or the payment, settlement or deferral thereof is subject to Section 409A of the Code, the option to purchase shares of Common Stock shall be granted, paid, exercised, settled or deferred in a manner that will comply with Section 409A of the Code, including the final regulations and other guidance issued with respect thereto, except as otherwise determined by the Board or a committee appointed by the Board. Notwithstanding the foregoing, the Company shall have no liability to a participant or any other party if the option to purchase Common Stock under the Plan that is intended to be exempt from or compliant with Section 409A of the Code is not so exempt or compliant or for any action taken by the Board or a committee appointed by the Board with respect thereto.

26. Governing Law. Except to the extent that provisions of this Plan are governed by applicable provisions of the Code or any other substantive provision of federal law, this Plan shall be construed in accordance with, and shall be governed by, the substantive laws of the State of California without regard to any provisions of California law relating to the conflict of laws.
