purpose without being succeeded within five Business Days by a post-effective amendment to the Shelf Registration Statement, a supplement to the Prospectus or a report filed with the Commission pursuant to Section 13(a), 13(c), 14 or 15(d) of the Exchange Act that

   (B)   in respect of any shares of Common Stock issued upon conversion of the Notes, to each holder of shares of Common Stock, (x) with respect to the first 90-day period in which a Registration

shall have occurred and be continuing, equal to 0.50% per annum of the principal amount of the Notes converted into such shares of Common Stock; provided that in no event shall Additional Amounts accrue at a rate per year exceeding 0.50% of the principal

such shares of Common Stock shall cease.  The Company agrees to deliver all notices, certificates and other documents contemplated by the Indenture in connection with the payment of Additional Amounts.

            The Additional Amounts set forth above shall be the exclusive monetary remedy available to the Holders of Transfer Restricted Securities for such
Registration Default.

Registration Procedures.

	
 


	
 

	
 

	
 

	
 

	
 


	
                (a)  In connection with the Shelf Registration
Statement, the Company shall comply with all the provisions of Section 4(b) hereof and shall use its reasonable efforts to effect such registration to permit the sale of the Transfer Restricted Securities being sold in accordance with the intended method or methods
of distribution thereof, and pursuant thereto, shall as expeditiously as possible prepare and file with the Commission a Shelf Registration Statement relating to the registration on any appropriate form under the Securities Act.


	
 

	
 

	
 

	
 

	
 


	
                (b)  In connection with the Shelf Registration
Statement and any Prospectus required by this Agreement to permit the sale or resale of Transfer Restricted Securities, the Company shall:


	
 

	
 

	
 

	
 

	
 


	
 

	
 

	
           (i)     Subject to any notice by the Company in accordance with this Section 4(b) of the existence of any fact or event of the kind
described in Section 4(b)(iii)(D) and the Company’s right to invoke a Suspension Period (as defined in below) in the manner described in this Section 4(b)(i), use its reasonable efforts to keep the Shelf Registration Statement continuously effective during the
Effectiveness Period; upon the occurrence of any event that would cause the Shelf Registration Statement or the Prospectus contained therein (A) to contain a material misstatement or omission or (B) not be effective and usable for resale of Transfer Restricted
Securities during the Effectiveness Period, unless a Suspension Period is then in effect the Company shall file promptly an appropriate amendment to the Shelf Registration Statement, a supplement to the Prospectus or a report filed with the Commission pursuant to
Section 13(a), 13(c), 14 or 15(d) of the Exchange Act, in the case of clause (A), correcting any such misstatement or omission, and, in the case of either clause (A) or (B), use its reasonable efforts to cause such amendment to be declared effective and the Shelf
Registration Statement and the related Prospectus to become usable for their intended purposes as soon as practicable thereafter.  Notwithstanding the foregoing, the Company may suspend the effectiveness of the Shelf Registration Statement by written notice to
the Holders for a period not to exceed an aggregate of 30 days in any 90-day period, or 90 days in any 360-day period (each such period, a “Suspension Period”), if:


	
 

	
 

	
 

	
 

	
 


	
6.









	
 

	
 

	
 

	
     (x)   an event occurs and is continuing as a result of which the Shelf Registration Statement would, in the Company’s reasonable judgment, contain an untrue statement of a material
fact or omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading; and

	
 


	
 

	
 

	
 

	
 

	
 


	
 

	
 

	
 

	
     (y)   the Company reasonably determines that the disclosure of such event at such time would have a material adverse effect on the business of the Company and its subsidiaries, taken as
a whole;

	
 


	
 

	
 


	
 

	
 

	
provided that, in the event the disclosure relates to a previously undisclosed proposed or pending material business transaction, the disclosure of which the Company’s board of directors determines would
impede the Company’s ability to consummate such transaction, the Company may extend a Suspension Period from 30 days to 60 days; provided, however, that Suspension Periods shall in no event exceed an aggregate of 90 days in any 360-day period.  The
Company shall not be required to specify in the written notice to the Holders the nature of the event giving rise to the Suspension Period.


	
 

	
 


	
 

	
 

	
           (ii)     Prepare and file with the Commission such amendments and post-effective amendments to the Shelf Registration Statement as may
be necessary to keep the Shelf Registration Statement effective during the Effectiveness Period; cause the Prospectus to be supplemented by any required Prospectus supplement, and as so supplemented to be filed pursuant to Rule 424 under the Securities Act, and to
comply fully with the applicable provisions of Rules 424 and 430A under the Securities Act in a timely manner; and comply with the provisions of the Securities Act with respect to the disposition of all securities covered by the Shelf Registration Statement during
the applicable period in accordance with the intended method or methods of distribution by the sellers thereof set forth in the Shelf Registration Statement or supplement to the Prospectus.


	
 

	
 


	
 

	
 

	
           (iii)     Advise the underwriter(s), if any, and selling Holders promptly (but in any event within three Business Days) and, if
requested by such Persons, to confirm such advice in writing:


	
 

	
 


	
 

	
 

	
 

	
                   (A) when the Prospectus or any Prospectus supplement or post-effective amendment has been filed, and, with
respect to the Shelf Registration Statement or any post-effective amendment thereto, when the same has become effective;

                   (C) of the issuance by the Commission of any stop order suspending the effectiveness of the Shelf
Registration Statement under the Securities Act or of the suspension by any state securities commission of the qualification of the Transfer Restricted Securities for offering or sale in any jurisdiction, or the initiation of any proceeding for any of the preceding
purposes; or

	
 


	
 

	
 

	
 

	
 

	
 


	
 

	
 

	
 

	
                   (D) of the existence of any fact or the happening of any event, during the Effectiveness Period (but not as
to the substance of any such fact or event), that makes any statement of a material fact made in the Shelf Registration Statement, the Prospectus, any amendment or supplement thereto, or any document incorporated by reference therein untrue, or that requires the
making of any additions to or changes in the Shelf Registration Statement or the Prospectus in order to make the statements therein not misleading.

	
 


	
 

	
 

	
 

	
 

	
 


	
 

	
 

	
      If at any time the Commission shall issue any stop order suspending the effectiveness of the Shelf Registration Statement, or any state securities commission or other regulatory authority
shall issue an order suspending the qualification or exemption from qualification of the Transfer Restricted Securities under state securities or Blue Sky laws, the Company shall use its reasonable efforts to obtain promptly the withdrawal or lifting of such order
and will provide to the Initial Purchasers and each Holder who is named in the Shelf Registration Statement prompt notice of the withdrawal of any such order.

	
 


	
 


	
 

	
 

	
           (iv)     If requested by any selling Holders or the underwriter(s), if any, promptly incorporate in the Shelf Registration Statement or
Prospectus, pursuant to a supplement or post‐effective amendment if necessary, such information as such selling Holders and underwriter(s), if any, may reasonably request to have included therein, including, without limitation: (1) information relating to the
“Plan of Distribution” of the Transfer Restricted Securities, (2) information with respect to the principal amount of Notes or number of shares of Common Stock issuable upon conversion of Notes being sold to such underwriter(s), (3) the purchase price

information that relates to the Transfer Restricted Securities to be sold by such selling Holder; and make all required filings of such Prospectus supplement or post‐effective amendment as soon as reasonably practicable after the Company is notified of the
matters to be incorporated in such Prospectus supplement or post‐effective amendment.

           (vi)     Deliver to each selling Holder and each of the underwriter(s), if any, without charge, as many copies of the Prospectus

           (B)     deliver such other documents and certificates as may be reasonably requested by such parties to evidence compliance with clause

           (viii)     Before any public offering of Transfer Restricted Securities, cooperate with the selling Holders, the underwriter(s), if
any, and their respective counsel in connection with the registration and qualification of the Transfer Restricted Securities under the securities or Blue Sky laws of such jurisdictions in the United States as the selling Holders or underwriter(s), if any, may
reasonably request and do any and all other acts or things necessary or advisable to enable the disposition in such jurisdictions of the Transfer Restricted Securities covered by the Shelf Registration Statement; provided, however, that the Company shall not
be required (A) to register or qualify as a foreign corporation or a dealer of securities where it is not now so qualified or to take any action that would subject it to the service of process in any jurisdiction where it is not now so subject or (B) to subject
itself to taxation in any such jurisdiction if it is not now so subject.


	
 


	
 

	
 

	
           (ix)     Cooperate with the selling Holders and the underwriter(s), if any, to facilitate the timely preparation and delivery of
certificates representing Transfer Restricted Securities to be sold and not bearing any restrictive legends (unless required by applicable securities laws); and enable such Transfer Restricted Securities to be in such denominations and registered in such names as the
Holders or the underwriter(s), if any, may request at least two Business Days before any sale of Transfer Restricted Securities made by such underwriter(s).


	
 


	
9.









	
 

	
 

	
           (x)     Use its reasonable efforts to cause the Transfer Restricted Securities covered by the Shelf Registration Statement to be
registered with or approved by such other U.S. governmental agencies or authorities as may be necessary to enable the seller or sellers thereof or the underwriter(s), if any, to consummate the disposition of such Transfer Restricted Securities.


	
 


	
 

	
 

	
           (xi)     Subject to Section 4(b)(i) hereof, if any fact or event contemplated by Section 4(b)(iii)(D) hereof shall exist or have
occurred, use its reasonable efforts to prepare a supplement or post‐effective amendment to the Shelf Registration Statement or related Prospectus or any document incorporated therein by reference or file any other required document so that, as thereafter
delivered to the purchasers of Transfer Restricted Securities, the Prospectus will not contain an untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary to make the statements therein, in light of the
circumstances in which they were made, not misleading; provided that the Company shall not be required to comply with the obligations in this Section 4(b)(xiii) during any Suspension Period.


	
 


	
 

	
 

	
           (xii)     Provide CUSIP numbers for all Transfer Restricted Securities not later than the effective date of the Shelf Registration
Statement and provide the Trustee under the Indenture with certificates for the Notes that are in a form eligible for deposit with The Depository Trust Company.


	
 


	
 

	
 

	
           (xiii)     Cooperate and assist in any filings required to be made with the NASD and the NYSE and in the performance of any due
diligence investigation by any underwriter that is required to be retained in accordance with the rules and regulations of the NASD and the NYSE.


	
 


	
 

	
 

	
           (xiv)     Otherwise use its reasonable efforts to comply with all applicable rules and regulations of the Commission and all reporting
requirements under the Exchange Act.


	
 


	
 

	
 

	
           (xv)     Cause the Indenture to be qualified under the TIA not later than the effective date of the Shelf Registration Statement
required by this Agreement, and, in connection therewith, cooperate with the Trustee and the holders of Notes to effect such changes to the Indenture as may be required for such Indenture to be so qualified in accordance with the terms of the TIA; and execute and use
its reasonable efforts to cause the Trustee thereunder to execute all documents that may be required to effect such changes and all other forms and documents required to be filed with the Commission to enable such Indenture to be so qualified in a timely
manner.


	
 


	
 

	
 

	
           (xvi)     Cause all Common Stock covered by the Shelf Registration Statement to be listed or quoted, as the case may be, on each
securities exchange or automated quotation system on which similar securities issued by the Company are then listed or quoted.


	
 


	
10.









	
                (c)  Each Holder agrees by acquisition of a Transfer Restricted Security that, upon
receipt of any notice from the Company of the existence of any fact of the kind described in Section 4(b)(iii)(D) hereof, such Holder will, and will use its reasonable efforts to cause any underwriter(s) in an Underwritten Offering to, forthwith discontinue
disposition of Transfer Restricted Securities pursuant to the Shelf Registration Statement until:


	
 


	
 

	
 

	
           (i)     such Holder has received copies of the supplemented or amended Prospectus contemplated by Section 4(b)(xiii) hereof;
or.


	
 


	
 

	
 

	
           (ii)     such Holder is advised in writing by the Company that the use of the Prospectus may be resumed, and has received copies of any
additional or supplemental filings that are incorporated by reference in the Prospectus.


	
 


	
Each Holder agrees to keep the existence and receipt of a Suspension Notice confidential.  If so directed by the Company, each Holder will deliver to the Company (at the Company’s expense) all copies, other than
permanent file copies then in such Holder’s possession, of the Prospectus covering such Transfer Restricted Securities that was current at the time of receipt of such notice of suspension.


	
 


	
                (d)  Each Holder who intends to be named as a selling Holder in the Shelf Registration
Statement shall complete the Questionnaire and deliver it to the Company within 20 Business Days after the date of a written request therefor by the Company (which request shall include a copy of the Questionnaire).  Holders who do not complete the Questionnaire
and deliver it to the Company prior to effectiveness of the Shelf Registration Statement shall not be eligible to be named as selling securityholders in the Prospectus or preliminary Prospectus included in the Shelf Registration Statement at the time of effectiveness
thereof and, therefore, shall not be permitted to sell any Transfer Restricted Securities pursuant to the Shelf Registration Statement.  Upon receipt of a completed Questionnaire following the effectiveness of the Shelf Registration Statement, the Company shall
use its reasonable efforts to file, within 10 Business Days after such Questionnaire is received, any amendments or supplements to the Shelf Registration Statement or supplements to a related Prospectus as are necessary to allow such Holder to be named as a selling
Holder in the Prospectus included therein and to permit such Holder to transfer its Transfer Restricted Securities pursuant to the Shelf Registration Statement.  The Company shall pay the Additional Amounts described in Section 3(a) to such Holder in respect of
such Holder’s Transfer Restricted Securities if the Company fails to make such filings within such period or, if such filing is a post-effective amendment, if such amendment is not declared effective within 45 days of such filing.  Notwithstanding any of
the foregoing, the Company shall not be required to file more than one post-effective amendment to the Shelf Registration Statement in any fiscal quarter.  In addition, each Holder who intends to be named as a selling Holder in the Shelf Registration Statement
shall promptly respond to the Company by providing such other information as the Company may from time to time reasonably request in writing regarding the Holder and the proposed distribution by such Holder of its Transfer Restricted Securities in connection with the
Shelf Registration Statement or Prospectus or preliminary Prospectus included therein.


	
 


	
11.









	
                (e)  Upon the effectiveness of the Shelf Registration Statement, each Holder shall
notify the Company at least three Business Days prior to any intended distribution of Transfer Restricted Securities pursuant to the Shelf Registration Statement (a “Sale Notice”), which notice shall be effective for five Business Days.  Each
Holder of Transfer Restricted Securities, by accepting the same, agrees to hold any communication by the Company in response to a Sale Notice in confidence.

                (a)  All expenses incident to the Company’s performance of or compliance with
this Agreement shall be borne by the Company regardless of whether a Shelf Registration Statement becomes effective, including, without limitation:


	
 

	
 

	
 

	
 

	
 


	
 

	
 

	
           (i)     all registration and filing fees and expenses (including filings made by any Initial Purchasers or Holders with the
NASD);

           (iii)     all expenses of printing (including printing of Prospectuses and certificates for the shares of Common Stock to be issued
upon conversion of the Notes) and the Company’s messenger and delivery services and telephone expenses;


	
 

	
 

	
 

	
 

	
 


	
 

	
 

	
           (iv)     all fees and disbursements of counsel to the Company and, subject to Section 5(b) below, the Holders of Transfer Restricted
Securities;


	
 

	
 

	
 

	
 

	
 


	
 

	
 

	
           (v)     all application and filing fees in connection with listing (or authorizing for quotation) the Common Stock issuable on
conversion of the Notes on a national securities exchange or automated quotation system pursuant to the requirements hereof; and


	
 

	
 

	
 

	
 

	
 


	
 

	
 

	
           (vi)     all fees and disbursements of independent certified public accountants of the Company (including the expenses of any special
audit and comfort letters required by or incident to such performance).


	
 


	
                The Company shall bear its internal expenses (including, without limitation, all salaries and expenses of its officers
and employees performing legal, accounting or other duties), the expenses of any annual audit and the fees and expenses of any Person, including special experts, retained by the Company.


	
 


	
                (b)  In connection with the Shelf Registration Statement required by this Agreement,
including any amendment or supplement thereto, and any other documents delivered to any Holders, the Company shall reimburse the Initial Purchasers and the Holders of Transfer Restricted Securities being registered pursuant to the Shelf Registration Statement, as
applicable, for the reasonable fees and disbursements of not more than one counsel, which shall be Simpson Thacher & Bartlett LLP, or such other counsel as may be chosen by a Majority of Holders for whose benefit the Shelf Registration Statement is being
prepared.  The Holders of Transfer Restricted Securities being registered shall be responsible for all underwriting commissions and discounts, if any, attributable to the sale of such Transfer Restricted Securities.

Indemnification and Contribution.

	
 


	
 

	
 

	
 

	
 

	
 


	
                (a)  The Company shall indemnify and hold harmless each Holder, such Holder’s officers, directors and
employees and each person, if any, who controls such Holder within the meaning of the Securities Act (each, an “Indemnified Holder”), from and against any loss, claim, damage or liability, joint or several, or any action in respect thereof
(including, but not limited to, any loss, claim, damage, liability or action relating to resales of the Transfer Restricted Securities), to which such Indemnified Holder may become subject, insofar as any such loss, claim, damage, liability or action arises out of,
or is based upon:


	
 

	
 

	
 

	
 

	
 


	
 

	
 

	
           (i)     any untrue statement or alleged untrue statement of a material fact contained in (A) the Shelf Registration Statement or
Prospectus or any amendment or supplement thereto or (B) any blue sky application or other document or any amendment or supplement thereto prepared or executed by the Company (or based upon written information furnished by or on behalf of the Company expressly for
use in such blue sky application or other document or amendment on supplement) filed in any jurisdiction specifically for the purpose of qualifying any or all of the Transfer Restricted Securities under the securities law of any state or other jurisdiction (such
application or document being hereinafter called a “Blue Sky Application”); or


	
 

	
 

	
 

	
 

	
 


	
 

	
 

	
           (ii)     the omission or alleged omission to state therein any material fact required to be stated therein or necessary to make the
statements therein, in the light of the circumstances under which they were made, not misleading,


	
 

	
 

	
 

	
 

	
 


	
and shall reimburse each Indemnified Holder promptly upon demand for any legal or other expenses reasonably incurred by such Indemnified Holder in connection with investigating or defending or preparing to defend against any
such loss, claim, damage, liability or action as such expenses are incurred; provided, however, that the Company shall not be liable in any such case to the extent that any such loss, claim, damage, liability or action arises out of, or is based upon,
(A) any untrue statement or alleged untrue statement or omission or alleged omission made in the Shelf Registration Statement or Prospectus or amendment or supplement thereto or Blue Sky Application or other document referred to in Section 6(a)(i) hereof in
reliance upon and in conformity with written information furnished to the Company by or on behalf of any Holder (or its related Indemnified Holder) specifically for use therein, or (B) the failure by the Holder or Indemnified Holder to deliver to any purchaser of its
Transfer Restricted Securities the Prospectus and any supplement or amendment thereto in the form provided to such Holder or Indemnified Holder by the Company if such Holder is required to so deliver pursuant to the prospectus delivery requirements of the Securities
Act.  The foregoing indemnity agreement is in addition to any liability which the Company may otherwise have to any Indemnified Holder.


	
 

	
 

	
 

	
 

	
 


	
                (b)  Each Holder, severally and not jointly, shall indemnify and hold harmless the
Company, its officers, directors and employees and each person, if any, who controls the Company within the meaning of the Securities Act, from and against any loss, claim, damage or liability, joint or several, or any action in respect thereof, to which the Company
or any such officer, director, employee or controlling person may become subject, insofar as any such loss, claim, damage or liability or action arises out of, or is based upon:


	
 

	
 

	
 

	
 

	
 


	
13.









	
 

	
 

	
           (i)     any untrue statement or alleged untrue statement of any material fact contained in the Shelf Registration Statement or
Prospectus or any amendment or supplement thereto or any Blue Sky Application or other document referred to in Section 6(a)(i) hereof; or


	
 

	
 

	
 

	
 

	
 


	
 

	
 

	
           (ii)     the omission or the alleged omission to state therein any material fact required to be stated therein or necessary to make the
statements therein, in light of the circumstances under which they were made, not misleading,


	
 

	
 

	
 

	
 

	
 


	
but in each case only to the extent that such untrue statement or alleged untrue statement or omission or alleged omission was made in reliance upon and in conformity with written information furnished to the Company by or on
behalf of such Holder (or its related Indemnified Holder) specifically for use therein, and shall reimburse the Company and any such officer, employee or controlling person promptly upon demand for any legal or other expenses reasonably incurred by the Company or any
such officer, employee or controlling person in connection with investigating or defending or preparing to defend against any such loss, claim, damage, liability or action as such expenses are incurred.  The foregoing indemnity agreement is in addition to any
liability which any Holder may otherwise have to the Company and any such officer, director, employee or controlling person.


	
 

	
 

	
 

	
 

	
 


	
                (c)  Promptly after receipt by an indemnified party under this Section 6 of notice of
any claim or the commencement of any action, the indemnified party shall, if a claim in respect thereof is to be made against the indemnifying party under this Section 6, notify the indemnifying party in writing of the claim or the commencement of that action;
provided, however, that the failure to notify the indemnifying party shall not relieve it from any liability which it may have under this Section 6 except to the extent it has been materially prejudiced by such failure and, provided, further, that the
failure to notify the indemnifying party shall not relieve it from any liability which it may have to an indemnified party otherwise than under this Section 6.  If any such claim or action shall be brought against an indemnified party, and it shall notify the
indemnifying party thereof, the indemnifying party shall be entitled to participate therein and, to the extent that it wishes, jointly with any other similarly notified indemnifying party, to assume the defense thereof with counsel satisfactory to the indemnified
party.  After notice from the indemnifying party to the indemnified party of its election to assume the defense of such claim or action, the indemnifying party shall not be liable to the indemnified party under this Section 6 for any legal or other expenses
subsequently incurred by the indemnified party in connection with the defense thereof other than reasonable costs of investigation; provided, however, that a Majority of Holders shall have the right to employ a single counsel to represent jointly a Majority of
Holders and their respective officers, directors, employees and controlling persons who may be subject to liability arising out of any claim in respect of which indemnity may be sought by a Majority of Holders against the Company under this Section 6, if a Majority
of Holders seeking indemnification shall have been advised by counsel that there may be one or more legal defenses available to them and their respective officers, employees and controlling persons that are different from or additional to those available to the
Company and its officers, directors, employees and controlling persons, the fees and expenses of a single separate counsel shall be paid by the Company.  No indemnifying party shall:


	
 

	
 

	
 

	
 

	
 


	
14.









	
 

	
 

	
           (i)     without the prior written consent of the indemnified parties (which consent shall not be unreasonably withheld) settle or
compromise or consent to the entry of any judgment with respect to any pending or threatened claim, action, suit or proceeding in respect of which indemnification or contribution may be sought hereunder (whether or not the indemnified parties are actual or potential
parties to such claim or action) unless such settlement, compromise or consent includes an unconditional release of each indemnified party from all liability arising out of such claim, action, suit or proceeding; or


	
 

	
 

	
 

	
 

	
 


	
 

	
 

	
           (ii)     be liable for any settlement of any such action effected without its written consent (which consent shall not be unreasonably
withheld), but if settled with its written consent or if there be a final judgment for the plaintiff in any such action, the indemnifying party agrees to indemnify and hold harmless any indemnified party from and against any loss or liability by reason of such
settlement or judgment.


	
 

	
 

	
 

	
 

	
 


	
                (d)  If the indemnification provided for in this Section 6 shall for any reason be
unavailable or insufficient to hold harmless an indemnified party under Section 6(a) or 6(b) in respect of any loss, claim, damage or liability (or action in respect thereof) referred to therein, each indemnifying party shall, in lieu of indemnifying such indemnified
party, contribute to the amount paid or payable by such indemnified party as a result of such loss, claim, damage or liability (or action in respect thereof):


	
 

	
 

	
 

	
 

	
 


	
 

	
 

	
           (i)     in such proportion as is appropriate to reflect the relative benefits received by the Company from the offering and sale of the
Transfer Restricted Securities on the one hand and a Holder with respect to the sale by such Holder of the Transfer Restricted Securities on the other; or


	
 

	
 

	
 

	
 

	
 


	
 

	
 

	
           (ii)     if the allocation provided by clause (6)(d)(i) is not permitted by applicable law, in such proportion as is appropriate to
reflect not only the relative benefits referred to in clause 6(d)(i) but also the relative fault of the Company on the one hand and the Holders on the other in connection with the statements or omissions or alleged statements or alleged omissions that resulted in
such loss, claim, damage or liability (or action in respect thereof), as well as any other relevant equitable considerations.


	
 

	
 

	
 

	
 

	
 


	
The relative benefits received by the Company on the one hand and a Holder on the other with respect to such offering and such sale shall be deemed to be in the same proportion as the total net proceeds from the offering of
the Notes purchased under the Purchase Agreement (before deducting expenses) received by the Company on the one hand, bear to the total proceeds received by such Holder with respect to its sale of Transfer Restricted Securities on the other.  The relative fault
of the parties shall be determined by reference to whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Company on the one hand or the Holders on the
other, the intent of the parties and their relative knowledge, access to information and opportunity to correct or prevent such statement or omission.   The Company and each Holder agree that it would not be just and equitable if the amount of contribution
pursuant to this Section 6(d) were determined by pro rata allocation or by any other method of allocation that does not take into account the equitable considerations referred to in the first sentence of this paragraph (d).  The amount paid or payable by
an indemnified party as a result of the loss, claim, damage or liability, or action in respect thereof, referred to above in this Section 6 shall be deemed to include, for purposes of this Section 6, any legal or other expenses reasonably incurred by such indemnified
party in connection with investigating or defending or preparing to defend any such action or claim.  Notwithstanding the provisions of this Section 6, no Holder shall be required to contribute any amount in excess of the amount by which the total price at which
the Transfer Restricted Securities purchased by it were resold exceeds the amount of any damages which such Holder has otherwise been required to pay by reason of any untrue or alleged untrue statement or omission or alleged omission.  No person guilty of
fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation.  The Holders’ obligations to contribute as provided in this
Section 6(d) are several and not joint.

7.

	
Rule 144A.  In the event the Company is not subject to Section 13 or 15(d) of the Exchange Act, the Company hereby agrees with each Holder, for so long
as any Transfer Restricted Securities remain outstanding, to make available to any Holder or beneficial owner of Transfer Restricted Securities in connection with any sale thereof and any prospective purchaser of such Transfer Restricted Securities from such Holder
or beneficial owner, the information required by Rule 144A(d)(4) under the Securities Act in order to permit resales of such Transfer Restricted Securities pursuant to Rule 144A.

Participation in Underwritten Registrations.     The Holders of Transfer Restricted Securities covered by the Shelf Registration Statement who
desire to do so may sell such Transfer Restricted Securities in an Underwritten Offering if approved by the Company in its sole discretion; provided, however, that no Holder may participate in any Underwritten Registration hereunder unless such Holder:

	
 


	
 

	
 

	
 

	
 

	
 


	
 

	
 

	
           (i)     agrees to sell such Holder’s Transfer Restricted Securities on the basis provided in any underwriting arrangements
approved by the Persons entitled hereunder to approve such arrangements; and


	
 

	
 

	
 

	
 

	
 


	
 

	
 

	
           (ii)     completes and executes all reasonable questionnaires, powers of attorney, indemnities, underwriting agreements, lock-up
letters and other documents required under the terms of such underwriting arrangements.


	
 

	
 

	
 

	
 

	
 


	
               

	
9.

	
Selection of Underwriters.    In any Underwritten Offering, the investment banker or investment bankers and manager or managers that will administer the offering
will be selected by a Majority of Holders whose Transfer Restricted Securities are included in such offering.

Miscellaneous.

	
 


	
 

	
 

	
 

	
 

	
 


	
                (a)  Remedies.  The Company acknowledges and agrees that any failure by the Company to
comply with its obligations under Section 2 hereof may result in material irreparable injury to the Initial Purchasers or the Holders for which there is no adequate remedy at law, that it will not be possible to measure damages for such injuries precisely and that,
in the event of any such failure, the Initial Purchasers or any Holder may obtain such relief as may be required to specifically enforce the Company’s obligations under Section 2 hereof; provided that specific performance shall be the sole equitable
remedy available to Holders hereunder.  The Company further agrees to waive the defense in any action for specific performance that a remedy at law would be adequate.


	
 

	
 

	
 

	
 

	
 


	
16.









	
                (b)  Actions Affecting Transfer Restricted Securities.  The Company
shall not, directly or indirectly, take any action with respect to the Transfer Restricted Securities as a class that would adversely affect the ability of the Holders of Transfer Restricted Securities to include such Transfer Restricted Securities in a registration
undertaken pursuant to this Agreement.


	
 

	
 

	
 

	
 

	
 


	
                (c)  No Inconsistent Agreements.  The Company will not, on or after
the date of this Agreement, enter into any agreement with respect to its securities that is inconsistent with the rights granted to the Holders in this Agreement or otherwise conflicts with the provisions hereof.  In addition, the Company shall not grant to any
of its security holders (other than the Holders of Transfer Restricted Securities in such capacity) the right to include any of its securities in the Shelf Registration Statement provided for in this Agreement other than the Transfer Restricted Securities.  The
Company has not previously entered into any agreement (which has not expired or been terminated) granting any registration rights with respect to its securities to any Person which rights conflict with the provisions hereof.


	
 

	
 

	
 

	
 

	
 


	
                (d)  Amendments and Waivers.  This Agreement may not be amended,
modified or supplemented, and waivers or consents to or departures from the provisions hereof may not be given, unless the Company has obtained the written consent of a Majority of Holders or such greater percentage of the Holders as required by the
Indenture.


	
 

	
 

	
 

	
 

	
 


	
                (e)  Notices.  All notices and other communications provided for or
permitted hereunder shall be made in writing by hand‐delivery, first‐class mail (registered or certified, return receipt requested), telex, facsimile transmission, or air courier guaranteeing overnight delivery:

QUANTUM CORPORATION


FORM OF SELLING SECURITYHOLDER NOTICE AND QUESTIONNAIRE


        The undersigned beneficial owner of 4.375% Convertible Subordinated Notes due 2010 (CUSIP No. 747906 AD 7) (the “Notes”), or common stock, par value $0.01
issuable upon conversion thereof (the “Common Stock” and together with the Notes, the “Transfer Restricted Securities”) of Quantum Corporation, a Delaware corporation (the “Company”), understands that the
Company has filed, or intends shortly to file, with the Securities and Exchange Commission (the “Commission”) a registration statement on Form S-3 or such other form as may be available (the “Shelf Registration Statement”), for
the registration and resale under Rule 415 of the Securities Act of 1933, as amended (the “Securities Act”), of the Transfer Restricted Securities in accordance with the terms of the Resale Registration Rights Agreement, dated as of July 30, 2003
(the “Registration Rights Agreement”) among the Company, Lehman Brothers Inc., Morgan Stanley & Co. Incorporated and McDonald Investments Inc.  A copy of the Registration Rights Agreement is available from the Company upon request at the
address set forth below.  All capitalized terms not otherwise defined herein have the meaning ascribed thereto in the Registration Rights Agreement.


        Each beneficial owner of Transfer Restricted Securities is entitled to the benefits of the Registration Rights Agreement.  In order to sell or otherwise dispose of any
Transfer Restricted Securities pursuant to the Shelf Registration Statement, a beneficial owner of Transfer Restricted Securities generally will be required to be named as a selling securityholder in the related Prospectus, deliver a Prospectus to purchasers of
Transfer Restricted Securities and be bound by those provisions of the Registration Rights Agreement applicable to such beneficial owner (including certain indemnification rights and obligations, as described below).  Beneficial owners that do not complete this
Notice and Questionnaire and deliver it to Quantum will not be permitted to be named as selling securityholders in the prospectus included in the Shelf Registration statement at the time of effectiveness thereof and, therefore, will not be permitted to sell any
Transfer Restricted Securities pursuant to the Shelf Registration Statement.  The Company has obligations to use its reasonable efforts to name beneficial owners in the Shelf Registration Statement as selling securityholders in certain other circumstances
described in the Registration Rights Agreement.  The Company has agreed to pay additional amounts pursuant to the Registration Rights Agreement under certain circumstances as set forth therein.


        Upon any sale of Transfer Restricted Securities pursuant to a Shelf Registration Statement, the undersigned beneficial owner (the “Selling Securityholder”)
will be required to deliver to the Company and the trustee for the Notes the Notice to Transfer (completed and signed) set forth in Exhibit 1 to this Notice and Questionnaire.


        Certain legal consequences arise from being named as a selling securityholder in the Shelf Registration Statement and the related Prospectus.  Accordingly, holders and
beneficial owners of Transfer Restricted Securities are advised to consult their own securities law counsel regarding the consequences of being named or not being named as a selling securityholder in the Shelf Registration Statement and the related
Prospectus.
