shall cause a notice to be mailed to Holders of the Notes, with a copy to the Trustee for the Notes, describing the transaction or transactions that constitute or may constitute the Change of Control Triggering Event and offering to repurchase the
Notes on the date specified in the notice, which date shall be no earlier than 30 days and no later than 60 days from the date such notice is mailed (the “Change of Control Payment Date”), pursuant to the procedures required by the
Notes and described in such notice. The notice shall, if mailed prior to the date of consummation of the Change of Control, state that the offer to purchase is conditioned on the Change of Control Triggering Event occurring on or prior to the Change
of Control Payment Date. Upon 10 Business Days’ advance notice to the Trustee, the Company may request the Trustee to mail the notice to Holders described in this Section 2.8(b) in the name of and at the expense of the Company. 

(c) The Company shall comply with the requirements of Rule 14e-1 under the Exchange Act and any other securities laws and regulations thereunder to
the extent such laws and regulations are applicable in connection with the repurchase of Notes as a result of a Change of Control Triggering Event. To the extent that the provisions of any such securities laws or regulations conflict with this
Section 2.8, the Company shall comply with those securities laws and regulations and shall not be deemed to have breached its obligations under this Section 2.8 by virtue of such conflict. 
 (d) On the Change of Control Payment Date, the Company shall, to the extent lawful:

Officer’s Certificate stating the aggregate principal amount of Notes or portions of Notes being purchased by the Company. 
 (e) The
Paying Agent shall promptly mail, to each Holder who properly tendered Notes, the purchase price for such Notes, and the Trustee shall promptly authenticate and mail (or cause to be transferred by book entry) to each such Holder a new Note equal in
principal amount to any unpurchased portion of the Notes surrendered, if any; provided that each new Note will be in a principal amount of $2,000 or an integral multiple of $1,000 in excess thereof. 
 (f) The Company shall not be required to make a Change of Control Offer upon a Change of Control Triggering Event if a third party makes a Change of
Control Offer in the manner, at the times and otherwise in compliance with the requirements set forth in this Fourth Supplemental Indenture applicable to a Change of Control Offer made by the Company and purchases all Notes properly tendered and not
withdrawn under such Change of Control Offer. In the event that such third party terminates or defaults on its Change of Control Offer, the Company shall be required to make a Change of Control Offer treating the date of such termination or default
as though it were the date of the Change of Control Triggering Event. 
 (g) The Company shall not be required to purchase any Notes if there
has occurred and is continuing on the Change of Control Payment Date an Event of Default under the Indenture, other than a default in the payment of the Change of Control Payment.

Significant Subsidiary then existing or thereafter created which is not subordinated to the Notes) equally and ratably with (or, at the Company’s option, prior to) such secured Indebtedness. 
 The foregoing restriction, however, shall not require the Company to secure the Notes if the Lien consists of either of the following:

Redemption Date; or

the Optional Redemption Price of and accrued interest on the Notes to be redeemed on that date. If less than all of the Notes are to be redeemed, the Notes to be redeemed shall be selected by the Trustee pro rata or by lot or by a method the Trustee
deems to be fair and appropriate; provided that if at the time of redemption the Notes to be redeemed are registered as one or more Global Securities, the Depositary shall determine, in accordance with its procedures, the principal amount of
the Notes to be redeemed held by each Holder of such Notes.

 [FORM OF REVERSE OF SECURITY] 
 This Security is one of a duly authorized issue of securities of the Company (herein called the “Securities”), issued and to be issued
in one or more series under a Senior Debt Indenture, dated as of August 12, 2008 (the “Base Indenture”), as supplemented by the Fourth Supplemental Indenture, dated as of February 9, 2009 (the “Supplemental
Indenture” and, together with the Base Indenture, the “Indenture”), between the Company and U.S. Bank National Association, as Trustee (herein called the “Trustee,” which term includes any successor trustee
under the Indenture), and reference is hereby made to the Indenture for a statement of the respective rights, limitations of rights, duties and immunities thereunder of the Company, the Trustee and the Holders of the Securities and of the terms upon
which the Securities are, and are to be, authenticated and delivered. This Security is one of the series designated on the face hereof initially limited in aggregate principal amount to $750,000,000, provided that the Company may, without the
consent of any Holder, at any time and from time to time increase the initial principal amount. 
 The Securities of this series are subject
to redemption as provided in Section 4.1 of the Supplemental Indenture and Article XI of the Base Indenture. 
 This Security will not
be subject to any sinking fund. 
 The Indenture contains provisions for defeasance at any time of the entire indebtedness of this Security
or certain restrictive covenants and Events of Default with respect to this Security, in each case upon compliance with certain conditions set forth in the Indenture. 
 If an Event of Default with respect to Securities of this series shall occur and be continuing, the principal of, and premium, if any, plus accrued and unpaid interest on the Securities of this series may be declared
due and payable in the manner and with the effect provided in the Indenture. 
 The Indenture permits, with certain exceptions as therein
provided, the amendment thereof and the modification of the rights and obligations of the Company and the rights of the Holders of the Securities of each series to be affected under the Indenture at any time by the Company and the Trustee with the
consent of the Holders of a majority in principal amount of the Securities at the time Outstanding of each series to be affected. The Indenture also contains provisions permitting the Holders of not less than a majority in principal amount of the
Securities of each series at the time Outstanding, on behalf of the Holders of all Securities of such series, to waive compliance by the Company with certain provisions of the Indenture and certain past defaults under the Indenture and their
consequences. Any such consent or waiver by the Holder of this Security shall be conclusive and binding upon such Holder and upon all future Holders of this Security and of any Security issued upon the registration of transfer hereof or in exchange
herefor or in lieu hereof, whether or not notation of such consent or waiver is made upon this Security. 
 As provided in and subject to the
provisions of the Indenture, the Holder of this Security shall not have the right to institute any proceeding with respect to the Indenture or for the appointment of a receiver or trustee or for any other remedy thereunder, unless such Holder shall
have previously given the Trustee written notice of a continuing Event of Default with respect to the Securities of this series, the Holders of not less than 25% in principal amount of the Securities of this series at the time Outstanding shall have
made written request to the Trustee to institute proceedings in respect of such Event of Default as Trustee and offered the Trustee reasonable indemnity, and the Trustee shall not have received from the Holders of a majority in principal amount of
Securities of this series at the time Outstanding a direction inconsistent with such request, and shall have failed to institute any such proceeding, for 60 days after receipt of such notice, request and offer of indemnity. The foregoing shall not
apply to any suit instituted by the Holder of this Security for the enforcement of any payment of principal hereof or any premium or interest hereon on or after the respective due dates expressed herein. 
 No reference herein to the Indenture and no provision of this Security or of the Indenture shall alter or impair the obligation of the Company, which is
absolute and unconditional, to pay the principal of and any premium and interest on this Security at the times, place and rate, and in the coin or currency, herein prescribed. 
  

 A-R-1 

 As provided in the Indenture and subject to certain limitations therein set forth, the transfer of this
Security is registrable in the Security Register, upon surrender of this Security for registration of transfer at the office or agency of the Company in any place where the principal of and any premium and interest on this Security are payable, duly
endorsed by, or accompanied by a written instrument of transfer in form satisfactory to the Company and the Security Registrar duly executed by, the Holder hereof or his attorney duly authorized in writing, and thereupon one or more new Securities
of this series and of like tenor, of authorized denominations and for the same aggregate principal amount, will be issued to the designated transferee or transferees. 
 The Securities of this series are issuable only in registered form without coupons in minimum denominations of $2,000 and integral multiples of $1,000 in excess thereof. As provided in the Indenture and subject to
certain limitations therein set forth, Securities of this series are exchangeable for a like aggregate principal amount of Securities of this series and of like tenor of a different authorized denomination, as requested by the Holder surrendering
the same. 
 No service charge shall be made for any such registration of transfer or exchange, but the Company may require payment of a sum
sufficient to cover any tax or other governmental charge payable in connection therewith. 
 Prior to due presentment of this Security for
registration of transfer, the Company, the Trustee and any agent of the Company or the Trustee may treat the Person in whose name this Security is registered as the owner hereof for all purposes, whether or not this Security be overdue, and neither
the Company, the Trustee nor any such agent shall be affected by notice to the contrary. 
 This Security and all the obligations of the

 BakBone is entitled to terminate this Agreement for Cause or without Cause at any time with no less than
two (2) days notice. If terminated for Cause, BakBone shall only be responsible to pay to you any and all base salary and accrued PTO, less all applicable withholdings and deductions, that has been earned prior to the effective date of
termination, and, if applicable, payment in lieu of such notice (“Notice Payment”) of the base salary and accrued PTO amounts entitled to for such two (2) day period. 
 If employment is terminated without Cause by BakBone and provided that you enter into a settlement
and release agreement with BakBone within thirty (30) days following the date of your termination, which agreement shall be negotiated in good faith by both parties, BakBone shall only be responsible to pay to you (a) any and all base
salary and accrued PTO, less all applicable withholdings and deductions, that has been earned prior to the effective date of termination, and (b) six (6) month’s base pay as severance pay, less all applicable withholdings and
deductions. This amount shall be paid in a lump sum no later than the date that is 2  1/2 months following the end of the
calendar year in which you are terminated. 
 You are entitled to terminate
this Agreement for Good Reason or without Good Reason at any time with no less than two (2) days notice, (provided, that BakBone has thirty (30) days following your notice of non-acquiescence to cure its failure to perform under this
Agreement). If employment is terminated for Good Reason by you, and provided that you enter into a settlement and release agreement with BakBone within thirty (30) days following the date your termination of employment, which agreement shall be
negotiated in good faith by both parties, BakBone shall only be responsible to pay to you (a) any and all base salary and accrued PTO, less all applicable withholdings and deductions, that has been earned prior to the effective date of
termination, and (b) six (6) month’s base pay as severance pay, less all applicable withholdings and deductions. If employment is terminated without Good Reason by you, BakBone shall only be responsible to pay to you any and all base

 Upon any termination of employment, you will also remain entitled to reimbursement of all appropriate expenses incurred during the performance of your employment duties for BakBone. The following provisions shall be
in effect for any reimbursements to which you are entitled to under this Agreement, in order to assure that such reimbursements do not create a deferred compensation arrangement subject to Section 409A of the Internal Revenue Code of 1986, as
amended (“Code”): 
 (a) The amount of reimbursements to which you may become entitled in any one calendar year shall not affect
the amount of expenses eligible for reimbursement hereunder in any other calendar year. 
  

 -3- 

 (b) Each reimbursement to which you become entitled shall be made by BakBone as soon as administratively
practicable following your submission of the supporting documentation, but in no event later than the close of business of the calendar year following the calendar year in which the reimbursable expense is incurred. 
 (c) Your right to reimbursement cannot be liquidated or exchanged for any other benefit or payment. 
 Notwithstanding any inconsistent provision of this Agreement, if you are a “specified employee” within the meaning of Code Section 409A at
the time of your termination, then the portion of your severance pay, together with any other severance payments or benefits that, in each case, may be considered deferred compensation under Code Section 409A, that would otherwise be payable
within the six (6) month period following your termination will be paid in a lump sum on the date six (6) months and one (1) day following the date of your termination (or the next business day if such date is not a business day) or,
if earlier, the date of death, provided you have complied with the requirements for such payment. Notwithstanding anything herein to the contrary, no actions taken pursuant to this paragraph shall reduce the total amount of payments and benefits
owed to you and to be paid to you under this offer of employment. 
 Notwithstanding any of the above in this Termination Provisions section,
if your employment is terminated as described in the Change in Control Letter Agreement that accompanies this Agreement, then this Termination Provisions section is of no force or effect and does not apply and the terms and conditions stated in the
Change of Control Letter Agreement shall be controlling. 
 Arbitration 
 We each agree that, to the extent permitted by law, all claims or disputes between you and BakBone, or its officers, employees or affiliates, will be
resolved by final, binding arbitration, in accordance with the employment dispute resolution rules of American Arbitration Association. This Agreement includes disputes of any nature, including, without limitation, all claims for any alleged
unlawful employment practice, discrimination, harassment, termination of employment, or any other disputes which may hereafter advise. The arbitration provision does not apply, however, to actions to obtain injunctive relief with respect to the
accompanying Terms of Employment agreement or to unemployment compensation or worker’s compensation. You will cooperate with BakBone in selecting a neutral arbitrator. The arbitrator shall apply California law without reference to conflicts of
law principles. The arbitration shall be held in San Diego, California. You and BakBone will be permitted to conduct discovery as would otherwise be permitted pursuant to the California Code of Civil Procedure. BakBone will pay the administrative
costs and arbitrator’s fees associated with the 

  

 -4- 

 
arbitration, provided however, that, unless the arbitrator rules otherwise under the provision below entitled “Attorney’s Fees”, you and
BakBone will each bear your own attorneys’ fees and costs associated with the arbitration. The arbitrator may not modify or change this Agreement in any way unless any provision is found to be unenforceable, in which case the arbitrator may
sever it. You understand and agree that the arbitrator’s decision shall be in writing with sufficient explanation to allow for such meaningful judicial review as may be permitted by law. Any award issued as a result of such arbitration shall be
final and binding and shall be enforceable by any court having jurisdiction over the party against whom enforcement is sought, provided, however, that no action to enforce an arbitration award shall be filed with the court until thirty
(30) days has passed after issuance of an award and the award has remained unpaid. You and BakBone acknowledge and understand that by signing this offer letter and by initialing the arbitration provision, each has read and understood the
arbitration provision; each agrees to be bound by it; and each is waiving their respective rights to have a dispute between them adjudicated by a court or by a jury.

 In the event any legal action is instituted to construe or enforce this Agreement or any provision hereof, the prevailing party shall

 At-Will Employment 
 At BakBone, employment is at-will. This means that BakBone or you may terminate your employment at any time, with or without cause or notice. This at-will
employment relationship exists regardless of any written statements or policies contained in the employee handbook or any other Company documents, or any verbal statement to the contrary. This at-will provision cannot be modified except in a written
agreement, signed by a Company officer and the employee, specifying a clear intent to alter the at-will nature of the employment relationship.

personnel acknowledgements, including, but not limited to BakBone’s Terms of Employment agreement as well as Parent’s Insider Trading Compliance Policy, Code of Business Conduct and Ethics Policy and Bakbone’s Employee Resource Manual
that are required of all employees and management. This offer of employment is also conditional in all respects to verification, as is acceptable to BakBone, including, but not limited to your authorization to work in the United States. BakBone is
an equal opportunity employer and does not discriminate based on any category protected by California or Federal law. All salary, bonuses, and allowances referred to in this Agreement will be considered normal income and will be subject to
applicable state and federal income taxes.
