 Exhibit 10.16 
  
 SUBLEASE AGREEMENT 
  
 This Sublease Agreement (“Sublease”) is made effective as of the 31st day of October, 2001, (the “Effective Date”) by and between
Entrust, Inc., a Maryland corporation (“Sublessor”), and Roxio, Inc., a Delaware corporation (“Sublessee”). Sublessor agrees to sublease to Sublessee, and Sublessee agrees to sublease from Sublessor, those certain premises
situated in the City of Santa Clara, County of Santa Clara, State of California, consisting initially of approximately 62,500 square feet of space known as 455 El Camino Real, Santa Clara, California, more particularly set forth on Exhibit
“A” hereto (the “Subleased Premises”). At such time as Sublessor vacates the Sublessor Premises the Subleased Premises shall be increased to approximately 75,000 square feet as set forth below. 
  
 ARTICLE 1 
  
 MASTER LEASE AND OTHER AGREEMENTS 
  
 1.1 Subordinate to Master Lease. Except as specifically set forth herein, this Sublease is subject and subordinate to
all of the terms and conditions of the lease (the “Original Lease”) entered into on November 14, 2000, between Sobrato Interests II, a California limited partnership (“Master Lessor”) and Sublessor as “Tenant” as
amended by that certain First Amendment to Lease dated July 26, 2001 (the “Amendment”). The Original Lease and the Amendment shall hereinafter collectively be referred to as the “Master Lease”. Sublessee hereby assumes and agrees
to perform the obligations of Lessee under the Master Lease as more particularly set forth hereafter. Unless otherwise defined, all capitalized terms used herein shall have the same meanings as given them in the Master Lease. A copy of the Master
Lease is attached hereto as Exhibit “B” and incorporated into this Sublease except to the extent excluded by this Sublease. Sublessee shall not commit or permit to be committed any act or omission which would violate any term or condition
of the Master Lease. Sublessee shall neither do nor permit anything to be done which would constitute a default (beyond applicable notice and cure periods) under the Master Lease, and Sublessee shall indemnify and hold Sublessor harmless from and
against all liability, judgments, costs, demands, claims, and damages of any kind whatsoever (including, without limitation, attorneys’ fees and court costs) by reason of such default. In the event of the termination of Sublessor’s
interest as Lessee under the Master Lease for any reason other than for Sublessor’s breach, then this Sublease shall terminate automatically upon such termination without any liability of Master Lessor or Sublessor to Sublessee except as set
forth herein. Sublessee represents and warrants to Sublessor that it has read and is familiar with the Master Lease. 
  
 Sublessor represents and warrants to Sublessee that the Master Lease is in full force and effect, the Master Lease attached as Exhibit B is a true and
complete copy of the Master Lease, and that there exists no amendments, modifications or other agreements (whether oral or written) affecting the Master Lease, that no default or event that, with the passing of time or the giving of notice or both,
would constitute a default, exists on the part of Sublessor, or, to Sublessor’s knowledge, the Master Lessor. Sublessor agrees to maintain the Master Lease in full force and effect, except to the extent that any failure to maintain the Master
Lease is due to the failure of Sublessee to comply with his obligations under this Sublease. Sublessor shall not voluntarily 
  

 1 

 terminate or amend or modify the Master Lease in such a manner as to materially adversely affect Sublessee’s use of
the Subleased Premises or increase the obligations or increase the rights of Sublessee hereunder, without the prior written consent of Sublessee, which shall not be unreasonably withheld. 
  
 1.2 Applicable Provisions. All of the terms and conditions contained in the Master Lease as they may apply to the
Subleased Premises, except those directly contradicted by the terms and conditions contained in this document, and specifically except for Paragraphs 1, 4A, 4C, 4D, 5, 6A, 6B, 13(i), the words “or vacation” in 13(ii), 14B, 17A(i) relating
to Landlord’s right to terminate lease and also then references to recapture in 17A, 18, 19C, Exhibit B, Exhibit C, Exhibit D and on the Amendment paragraphs 1, 2, and 3 are incorporated herein and shall be terms and conditions of this Sublease
(with each reference therein to “Landlord” or “Lessor”, “Tenant” or “Lessee” and “Lease” to be deemed to refer to Sublessor, Sublessee, and Sublease, respectively, as appropriate except the following
provisions that are incorporated herein, the reference to Landlord or Lessor shall mean Master Lessor only: 8A and 15), and along with all of the following terms and conditions set forth in this document, shall constitute the complete terms and
conditions of this Sublease. 
  
 1.3 Obligations of
Sublessor. Notwithstanding anything herein contained, the only services or rights to which Sublessee is entitled hereunder are those to which Sublessor is entitled under the Master Lease, and for all such services and rights Sublessee shall look
solely to the Master Lessor under the Master Lease, and the obligations of Sublessor hereunder shall be limited to using due diligence and its reasonable good faith efforts to obtain the performance by Master Lessor of its obligations. Such due
diligence and good faith efforts shall include (a) upon Sublessee’s written request, promptly notify Master Lessor of its non-performance under the Master Lease, and requesting that Master Lessor perform its obligations under the Master Lease,
and (b) upon Subtenant’s written request, if Master Lessor’s non-performance continues beyond any applicable cure periods provided in the Master Lease, commencing a lawsuit or other action against Master Lessor to obtain the performance
required from Master Lessor under the Master Lease. Sublessor shall have no liability to Sublessee or any other person for damage of any nature whatsoever as a result of the failure of Master Lessor to perform said obligations except for Master
Lessor’s termination of the Sublessor’s interest as Lessee under the Master Lease in the event of Sublessor’s breach of the Master Lease. Each party (the “Indemnifier”) shall defend, indemnify and hold the other (the
“Indemnified”) harmless from and against any damages, claims or costs (save for claims, damages or costs arising from consequential damages or damages for loss of profit) including attorneys’ fees incurred by the Indemnified
from the Indemnifier’s breach of the Master Lease. Each party’s obligations under this section shall survive the termination of this Sublease. 
  
 ARTICLE 2 
  
 TERM 
  
 2.1 Term. The term of this Sublease shall commence on the later of (i) April 1, 2002, or (ii) 30 days after the Sublease has been fully executed, the Subleased Premises are Substantially Complete (as defined herein) and Master
Lessor’s consent has been obtained pursuant to Article 10 herein. This shall be referred to as the “Commencement Date.” The term 
  

 2 

 of this Sublease shall end on November 30, 2006, unless sooner terminated pursuant to any provision of the Master Lease
applicable to the Subleased Premises or extended pursuant to Sublessee’s option to extend (the “Expiration Date”). Sublessor shall have no obligation to Sublessee to exercise any of its options to extend under the Master Lease.

  
 2.2 Option to Extend. Sublessee shall have the option
to extend the term of this Sublease for an additional period of fifty-three (53) months by giving Sublessor written notice of its intent to exercise such option to extend (the “Extension Option Notice”) at a time that is no later than six
(6) months nor earlier than eighteen (18) months prior to the initial Expiration Date. 
  
 2.3 Base Rent During the Option Period. Base rent during the option term shall be the fair market rent (“Fair Market Rent”) as agreed between the parties. If the parties cannot agree on Fair Market
Rent, it shall be determined as follows: If Sublessor and Sublessee are unable to agree on the Fair Market Rent within thirty (30) days after the date of the Extension Option Notice then Sublessor and Sublessee shall each select a licensed real
estate broker or sales person with at least seven (7) years experience in leasing comparable properties in the Santa Clara area to determine the Fair Market Rent for the Subleased Premises. Each broker shall each submit their estimate of the Fair
Market Rent within thirty (30) days of their selection to both Sublessor and Sublessee. If the Fair Market Rent each submits is with five percent (5%) of the other then the average of the two will be deemed the Fair Market Rent and will be the Base
Rent for the renewal term. If the difference is greater than five percent (5%) then a third broker shall be selected by the two previous brokers who shall then within ten (10) days of the third broker selection, determine which of the previous two
brokers’ rate is closest to the Fair Market Rent. The third broker shall notify Sublessor and Sublessee of the third brokers’ determination which shall be binding on both parties and shall be the Base Rent for the renewal term. 

 
 2.4 Sublessor’s Inability to Deliver Subleased Premises. In
the event Sublessor is unable to deliver possession of the Subleased Premises on or before the January 1, 2002, Sublessor shall not be liable for any damage caused thereby, nor shall this Sublease be void or voidable, but Sublessee shall not be
liable for Rent until such time as Sublessor offers to deliver possession of the Subleased Premises to Sublessee, but the term hereof shall not be extended by such delay. In the event Sublessor has been unable to deliver possession of the Subleased
Premises within thirty (30) days after February 1, 2002, Sublessee, at Sublessee’s sole option, may terminate this Sublease, and the Security Deposit and Prepaid Rent shall be returned to Sublessee. 
  
 2.5 Early Access. Sublessee and its vendors, consultants, contractors
and agents shall have full access to the Subleased Premises upon receipt of a fully executed Sublease and Master Lessor’s consent pursuant to Article 10 (“Early Access”). Such Early Access shall be subject to all the terms and
conditions of this Sublease, other than the payment of Rent.

Rent (April and May 2002). 
  
 3.3 Additional Rent. If
Sublessor shall be charged for additional rent or other sums pursuant to any of the provisions of the Master Lease, Sublessee shall be liable for its pro rata share (defined herein) of such additional rent or sums. Notwithstanding the foregoing or
anything to the contrary in this Sublease, Sublessee shall not be required to pay any additional rent or to perform any obligation that is (1) fairly allocable to any period of time prior to the Commencement Date or following the expiration or
sooner termination of this Sublease (for any reason other than Sublessee’s default), (2) fairly allocable to any portion of the Master Premises other than the Subleased Premises, (3) payable as a result of a default by Sublessor of any of its
obligations under the Master Lease, or as a result of the negligence or willful misconduct of Sublessor or any of its agents, employees, or contractors, or (4) incurred for the sole benefit of Sublessor. If Sublessee shall procure any additional
services from Master Lessor, or if additional rent or other sums are incurred for Sublessee’s sole benefit, Sublessee shall make such payment to Sublessor or Master Lessor, as Sublessor shall direct and such charges shall not be pro rated
between Sublessor and Sublessee. Any rent or other sums payable by Sublessee under this Article 3 shall constitute and be due as additional rent. Base Rent, Personal Property Rent and additional rent shall herein be referred to as “Rent”.

 3.4 Pro Rata Share. Sublessee’s pro rata share under this Sublease shall be calculated by
multiplying the total additional rent or other charge due by a fraction, the numerator of which shall be the approximate square footage of the Subleased Premises and the denominator of which shall be the approximate square footage of the entire
premises under the Master Lease. All measurements noted in this Section are included in the Master Lease. Sublessee acknowledges all square footage measurements noted and relied on in this Sublease and the Master Lease are estimates, and no
adjustments shall be made based upon any actual measurements which may be made. 
  
 ARTICLE 4 
  
 SECURITY
DEPOSIT 
  
 4.1 Security Deposit. Upon execution
hereof, Sublessee shall deposit with Sublessor the sum of Two Hundred Six Thousand Two Hundred Fifty and no/100 Dollars ($206,250.00) as and for a Security Deposit to secure Sublessee’s full and timely performance of all of its obligations
hereunder. If Sublessee fails to pay Rent or any other sums as and when due hereunder, or otherwise defaults with respect to any provision of this Sublease, Sublessor may (but shall not be obligated to) use, apply, or retain all or any portion of
said deposit for payment of any sum for which Sublessee is obligated or which will compensate Sublessor for any loss or damage which Sublessor may suffer thereby including, without limitation, any damage that will result in the future through the
term of the Sublease, to repair damage to the Subleased Premises or to clean the Subleased Premises at the end of the term. Any such use, application, or retention shall not constitute a waiver by Sublessor of its right to enforce its other remedies
hereunder, at law, or in equity. If any portion of said deposit is so used, applied, or retained, Sublessee shall, within ten (10) days after delivery of written demand from Sublessor, restore said deposit to its original amount. Sublessee’s
failure to do so shall constitute a material breach of this Sublease, and in such event Sublessor may elect, among or in addition to other remedies, to terminate this Sublease. Sublessor shall not be a trustee of such deposit, and shall not be
required to keep this deposit separate from its accounts. Sublessor alone shall be entitled to any interest or earnings thereon and Sublessor shall have the free use of same. If Sublessee fully and faithfully performs all of its obligations
hereunder, then so much of the deposit as remains shall be returned to Sublessee (without payment of interest or earnings thereon) within 30 days after the later of (i) expiration or sooner termination of the term hereof, or (ii) Sublessee’s
surrender of possession of the Subleased Premises to Sublessor.

consent which consent shall not be unreasonably withheld, conditioned or delayed. The consent by Sublessor and Master Lessor to any assignment or subletting shall not waive the need for Sublessee (and Sublessee’s assignee or subtenant) to
obtain the consent of Sublessor and Master Lessor to any different or further assignment or subletting. Except as set forth herein, all provisions set forth in the Master Lease regarding assignments and subletting shall apply, and to the extent

Rent and to perform all other obligations to be performed by Sublessee hereunder. The acceptance of Rent by Sublessor from any other person shall not be deemed to be a waiver by Sublessor of any provision hereof. In the event of default by any
assignee, subtenant or any other successor of Sublessee, in the performance of any of the terms hereof, Sublessor may proceed directly against Sublessee without the necessity of exhausting remedies against such assignee, subtenant or successor.

Master Lease to the contrary, Sublessor shall have no right to recapture all or any portion of the Subleased Premises in the event of a sublease or assignment by Sublessee.

permanent occupancy or its equivalent (if available) has been issued by the City or other applicable government agency for the Subleased Premises (subject only to completion of Initial Tenant Improvements, which shall be the responsibility of

 ARTICLE 13 
  
 NON-DISTURBANCE AGREEMENT & LETTER OF CREDIT 
  
 13.1 Non-Disturbance Agreement. Concurrently with the execution of the Sublease, Sublessor will provide Sublessee
with a non-disturbance agreement (“NDA”) in favor of Sublessee from the Master Lessor affecting the Subleased Premises and the Sublessor’s Premises. Any such NDA shall confirm the terms and conditions of the Sublease provided,
however, that Sublessee agrees to modify the rental provisions of the Sublease (specifically, the rent and rent increases) to reflect current fair market conditions (the “Fair Market Value”) as reasonably determined by the Master Lessor
and Sublessee, or alternatively by the same method 
  

 12 

 for determining Fair Market Rent as in Section 2.3. In addition, Master Lessor shall covenant and agree to
Sublessee’s quiet and peaceful possession of the Premises. 
  
 13.2 Letter of Credit. Concurrently with the execution of the Sublease, Sublessor shall deliver to Sublessee an irrevocable, unconditional, standby Letter of Credit (“LOC”) in the amount of $6,200,000.00 from a financial
institution reasonably approved by Sublessee (“Issuer”) to secure Sublessor’s obligation to Sublessee that it will perform all of its obligations under the Master Lease for the initial term of the Sublease and for any extended period
of attornment required by Master Lessor in its Consent to this Sublease. The LOC shall provide that draws, including partial draws, at Sublessee’s election will be honored upon the delivery to Issuer a certificate signed by Sublessee, or its
authorized agent, that Sublessee is entitled to make the requested draw pursuant to the terms of the Sublease. If Sublessor fails to pay rent or any other sums as and when due under the Master Lease, or otherwise defaults under the Master Lease,
Sublessee may, to the extent called upon by the Master Lessor to pay amounts in excess of those to be paid under this Sublease, use, apply or retain all or any portion of the LOC for payment of any sum for which Sublessor is obligated under the
Master Lease. Any draw or partial draw of the LOC shall not constitute a waiver by Sublessee of its right to enforce its other remedies hereunder, at law or in equity. The LOC shall be in effect for the entire initial term of this Sublease and for
any extended period of attornment required by Master Lessor in its Consent to this Sublease. The LOC will automatically renew each year during the Sublease term unless the beneficiary under the LOC is given at least thirty (30) days prior notice of
a non-renewal by the issuing bank and Sublessee shall be able to draw on the LOC in the event of such notice. The LOC shall be adjusted up or down on each anniversary of the Commencement Date of the Sublease to reflect the total difference
(undiscounted) between the Fair Market Value and the remaining rent due under the Sublease, except there shall be no downward adjustment if Sublessor is in default under the terms of the Master Lease. Example: Assume there are five (5) years
remaining in the term and that the average remaining rental rate is $3.09 per square foot per month. If the Sublessor and Sublessee agree that the then Fair Market Value is $4.00 per square foot per month with four percent (4%) annual increases, the
average Fair Market Value is $4.33 per square foot per month. Given these numbers, the LOC would be adjusted to $5,580,000.00 [($4.33 - $3.09) x 75,000 SF x 60 months = $5,580,000)]. Sublessee shall pay all reasonable fees associated with said LOC.

  
 13.3 Offer Letter. Not more than ninety (90) days and
not less then sixty (60) days prior to each anniversary of the Commencement Date of the Sublease, Sublessor shall deliver to Sublessee a letter (“Offer Letter”) with Sublessor’s opinion of the then Fair Market Value of the Premises to
determine the amount of the LOC for the next twelve (12) months. Sublessee shall have thirty (30) days (“Sublessee’s Review Period”) after receipt of the Offer Letter to accept or reject the Offer Letter in writing. If Sublessee
accepts the Offer Letter, Sublessor shall adjust the LOC accordingly prior to the applicable anniversary of the Sublease. If Sublessee rejects the Offer Letter, Sublessee and Sublessor shall use their best efforts to negotiate a mutually agreeable
Fair Market Value by the date that is thirty (30) days prior to the applicable anniversary date (“Outside Agreement Date”). 
  
 13.4 Arbitration. If Sublessor and Sublessee are unable to agree on the Fair Market Value on or before the Outside Agreement Date, then Sublessor
and Sublessee shall each select a licensed real estate broker or salesperson with at least seven (7) years experience in leasing 
  

 13 

 comparable properties in the Santa Clara area to determine the Fair Market Value of the Premises. Such brokers shall each
submit their Fair Market Value within thirty (30) business days of their selection to both Sublessor and Sublessee. If the Fair Market Value each submits is within five percent (5%) of the other, then the average of the two will be the Fair Market
Value used to adjust the LOC for the next twelve (12) months. If the difference is greater than five percent (5%) then a third broker shall be selected by the two previous brokers who shall then within ten (10) days of the third broker’s
selection determine which of the previous two brokers’ rate is closest to the Fair Market Rent. The third broker shall notify Sublessor and Sublessee of the third broker’s determination which shall be binding upon the parties. 

 
 ARTICLE 14 
  
 BROKER’S COMMISSIONS 
  
 14.1 Commission. Sublessor and Sublessee represent and warrant to each other that each has dealt with the following brokers: CPS/Corfac

asserted against the other by any broker, agent, finder, or other such person not identified above as Sublessor’s Broker or Sublessee’s Broker. The Commission to the Brokers is pursuant to separate agreement.

reasonable attorneys’ fees and court costs incurred by Sublessor in the litigation. 
  
 16.2 Certain Litigation Between the Parties. In the event any action or proceeding at law or in equity or any arbitration proceeding be instituted by either party, for an alleged breach of any obligation of
Sublessee under this Sublease, to recover rent, to terminate the tenancy of Sublessee at the Subleased Premises, or to enforce, protect, or establish any right or remedy of a party to this Sublease Agreement, the prevailing party (by judgment or
settlement) in such action or proceeding shall be entitled to recover as part of such action or proceeding such reasonable attorneys’ fees, expert witness fees, and court costs as may be fixed by the court or jury, but this provision shall not
apply to any cross-complaint filed by anyone other than Sublessor in such action or proceeding.
