FIFTH AMENDMENT TO SUBLEASE

THIS FIFTH AMENDMENT TO SUBLEASE (this “Fifth Amendment”) is made and entered
into as of July 10, 2013, by and between LUDLOW TECHNICAL PRODUCTS CORPORATION,
a New York corporation (“Sublandlord”), and SYNACOR, INC., a Delaware
corporation (“Subtenant”).

WITNESSETH:

A. Sublandlord is the tenant under that certain Property Lease dated March 13,
1998, with Waterfront Associates, LLC (“Landlord”), as landlord, covering
Building No. 3, Waterfront Village Center, 40 La Riviere Drive, Buffalo, New
York 14202 (the “Building”), as amended by that certain First Amendment to Lease
dated April 29, 1998, that Second Amendment to Lease dated April 21, 1999, that
Third Amendment to Lease dated July 30, 1999, and that Fourth Amendment to Lease
dated December 30, 2007 (collectively, the Property Lease and amendments thereto
are the “Lease”).

B. Under the terms and conditions of that certain Sublease dated as of March 3,
2006 (the “Original Sublease”), as amended by that certain First Amendment to
Sublease (“First Amendment”) dated September 25, 2006, that certain Second
Amendment to Sublease (“Second Amendment”) dated February 27, 2007, that certain
Third Amendment to Sublease (“Third Amendment”) dated June 3 0, 2010, and that
certain Fourth Amendment to Sublease (“Fourth Amendment”) dated May 21, 2013
(collectively, the “Sublease”), Subtenant subleased from Sublandlord
approximately 38,772 rentable square feet of space located on the first and
third floors of the Building (the “Existing Premises”), which Existing Premises
is more particularly described in the Sublease as the Premises.

C. Under the terms and conditions of the Sublease, Subtenant desires to sublease
additional space on the first floor of the Building, which additional space
contains approximately 6,284 rentable square feet of space and is more
particularly depicted as “Suite C” on Exhibit A, attached hereto and
incorporated herein (the “Suite C Premises”); and Sublandlord has agreed to
sublease such Suite C Premises to Subtenant on the terms and conditions of the
Sublease, as modified herein.

NOW THEREFORE, in consideration of the mutual covenants set forth herein, and
for other good and valuable consideration, the receipt and sufficiency of which
are hereby acknowledged, Sublandlord and Subtenant agree as follows:

1. Suite C Premises. Conditioned upon receipt by Sublandlord of Landlord’s
written consent executed in substantially the form attached hereto as Exhibit B,
Sublandlord hereby subleases to Subtenant, and Subtenant hereby subleases from
Sublandlord, the Suite C Premises on the terms and conditions of the Sublease,
as modified hereby. Accordingly, from and after the Effective Date (hereinafter
defined), the term “Premises” will refer collectively to the Existing Premises
and the Suite C Premises; the Premises will contain approximately 45,056
rentable square feet of space; and Subtenant’s Share shall be increased to
43.82%, which is the percentage obtained by dividing the number of rentable
square feet in the Premises (45,056) by the number of rentable square feet in
the Building (102,816). Sublandlord and Subtenant

 

Page 1 of 9

--------------------------------------------------------------------------------

stipulate that the number of rentable square feet in the Existing Premises, the
Suite C Premises, and the Building is correct.

2. Term for Suite C Premises. The term for the Suite C Premises shall begin on
the Effective Date and shall expire on the Expiration Date as set forth in
Section 2.3 of the Original Sublease (i.e., March 31, 2016). As used herein, the
“Effective Date” shall mean the earlier of (a) the date on which Subtenant
occupies any portion of the Suite C Premises and begins conducting business
therein, or (b) the date on which Sublandlord delivers to Subtenant possession
of the Suite C Premises. Subtenant shall accept possession of the Suite C
Premises on the date when Sublandlord tenders possession thereof to Subtenant.

Subtenant shall execute and deliver to Sublandlord, within ten days after
Sublandlord has requested the same, a letter confirming (i) the Effective Date,
and (ii) Subtenant has accepted the Suite C Premises.

3. Rent for Suite C Premises. The annual fixed rent due under the Sublease for
the Suite C Premises shall be $14.00 per rentable square foot in the Suite C
Premises, payable in equal monthly installments of $7,331.33 per month,
beginning on the Effective Date. Thus, commencing on the Effective Date, the
total monthly fixed rent due under the Sublease for the Premises shall be
$52,565.33.

4. Securitv Deposit. Contemporaneously with the execution hereof, and as a
condition to the effectiveness of this Fifth Amendment, Subtenant shall deliver
to Sublandlord an additional $7,331.33 to be held as part of the Security
Deposit under the Sublease. After such additional deposit, the Security Deposit
will total $52,565.33.

5. AS-IS Condition. Subtenant hereby accepts the Suite C Premises in their
presently existing “AS-IS” condition. Subtenant acknowledges that (a) it was
given a full opportunity to inspect the Suite C Premises; (b) as of the
Effective Date, Subtenant has inspected the Suite C Premises; and (c) neither
Sublandlord nor its agents or employees has made any representations or
warranties as to the condition of the Suite C Premises, or the suitability or
fitness of the Suite C Premises for the conduct of Subtenant’s business or for
any other purpose. Sublandlord has no obligation to perform any work,
alterations, or tenant improvements in the Suite C Premises (including without
limitation demolition of any improvements existing therein or construction of
any tenant finish-work or other improvements therein); and Sublandlord shall not
be obligated to reimburse Subtenant or provide an allowance for any costs
related to the demolition or construction of improvements therein.

6. Alterations. Subtenant shall not without Landlord and Sublandlord’s prior
written consent, which consent shall not be unreasonably withheld, make or
perform any alterations, additions, or improvements to the Premises
(collectively, “Alterations”). Subtenant shall request Sublandlord’s consent at
least thirty (30) days before the commencement of any construction, and
Subtenant shall provide, in connection with such consent request, plans and
specifications for such Alterations, which plans and specifications are subject
to Sublandlord’s approval, which shall not be unreasonably withheld as set forth
above. All Alterations shall be performed at Subtenant’s expense.

 

Page 2 of 9

--------------------------------------------------------------------------------

All Alterations performed by or on behalf of Subtenant shall be done in a good
and workmanlike manner by contractors reasonably approved by Sublandlord and in
accordance with Article 8 of the Original Sublease. Subtenant shall, at
Subtenant’s expense, before making any Alterations, (i) obtain all permits and
approvals required by any governmental authority and (upon completion thereof)
certificates of occupancy and any other certificates of final approval thereof,
and shall promptly deliver to Sublandlord copies of such permits and approvals;
and (ii) provide Sublandlord with certificates evidencing appropriate builder’s
risk, liability, and worker’s compensation insurance coverage in commercially
reasonable amounts during the performance of any such Alterations.

Any and all Alterations made by or on behalf of Subtenant in, to or upon the
Premises shall become the property of Sublandlord and shall remain upon and be
surrendered with the Premises unless Sublandlord elects to relinquish
Sublandlord’s right thereto and to have them removed by Subtenant, in which
event the same shall be removed from the Premises by Subtenant prior to the
Expiration Date, at Subtenant’s expense. Nothing in this Section shall be
construed to give Sublandlord title to or to prevent Subtenant’s removal of
trade fixtures or moveable office furniture or equipment, but upon removal of
any of the same or upon removal of other Alterations as may be required by
Sublandlord, Subtenant shall repair any damage to the Building or the Premises
caused by such removal, except structural damage, which, at Sublandlord’s
option, shall be repaired by Sublandlord at Subtenant’s expense. All Alterations
permitted or required to be removed by Subtenant remaining in the Premises after
the end of the Term shall be deemed abandoned and may, at the election of
Sublandlord, either be retained as Sublandlord’s property or removed from the
Premises by Sublandlord.

7. Right of First Offer. Subtenant and Sublandlord hereby acknowledge and agree
that the right of first offer set forth in Article 16 of the Original Sublease,
Section 5 of the First Amendment, Section 5 of the Second Amendment, Section 7
and Exhibit D of the Third Amendment, and Section 8 of the Fourth Amendment
(captioned “Right of First Offer”) is hereby deleted and has no further force or
effect.

Subject to then-existing renewal or expansion options of other subtenants, and
provided no default by Subtenant exists, Sublandlord shall, before offering the
same to any party (other than the then-current subtenant therein), first offer
to lease to Subtenant the space commonly known as Suite 200, which space
contains approximately 33,237 square feet of space, is located on the second
floor of the Building (the “Offer Space”) in an “AS-IS” condition; such offer
shall be in writing and specify the lease terms for the Offer Space, including
the rent to be paid for the Offer Space and the date on which the Offer Space
shall be included in the Premises (the “Offer Notice”). Sublandlord shall use
good faith in determining the rent amount for the Offer Space. The Offer Notice
shall be substantially similar to the Offer Notice attached to the Original
Sublease as Exhibit E. Subtenant shall notify Sublandlord in writing whether
Subtenant elects to lease the entire Offer Space on the terms set forth in the
Offer Notice, within ten (10) days after Sublandlord delivers to Subtenant the
Offer Notice. If Subtenant timely elects to lease the Offer Space, then
Sublandlord and Subtenant shall execute an amendment to this Sublease, effective
as of the date the Offer Space is to be included in the Premises, on the terms
set forth in the Offer Notice and, to the extent not inconsistent with the Offer
Notice terms, the terms of the Sublease; however, Subtenant shall accept the
Offer Space in an “AS-IS” condition. Notwithstanding the foregoing, if before
Sublandlord’s delivery to Subtenant of the Offer Notice, Sublandlord has

 

Page 3 of 9

--------------------------------------------------------------------------------

received an offer to lease all or part of the Offer Space from a third party (a
“Third Party Offer”) and such Third Party Offer includes space in excess of the
Offer Space, Subtenant must exercise its rights hereunder, if at all, as to all
of the space contained in the Third Party Offer.

If Subtenant fails or is unable to timely exercise its right hereunder, then
such right shall lapse, time being of the essence with respect to the exercise
thereof (it being understood that Subtenant’s right of first offer hereunder is
a one-time right only with respect to each Offer Space), and Sublandlord may
lease all or a portion of the Offer Space to third parties on such terms as
Sublandlord may elect. Subtenant may not exercise its rights under this Section
7 if a default exists or Subtenant is not then occupying the entire Premises.
For purposes hereof, if an Offer Notice is delivered for less than all of the
Offer Space but such notice provides for an expansion, right of first refusal,
or other preferential right to lease some of the remaining portion of the Offer
Space, then such remaining portion of the Offer Space shall thereafter be
excluded from the provisions of this Sublease. In no event shall Sublandlord be
obligated to pay a commission with respect to any space leased by Subtenant
under this Section 7, and Subtenant and Sublandlord shall each indemnify the
other against all costs, expenses, attorneys’ fees, and other liability for
commissions or other compensation claimed by any broker or agent claiming the
same by, through, or under the indemnifying party.

Subtenant’s rights under this Section 7 shall terminate if (a) this Sublease or
Subtenant’s right to possession of the Premises is terminated, (b) Subtenant
assigns any of its interest in this Sublease or sublets any portion of the
Premises, or (c) less than two full calendar years remain in the initial Term of
this Sublease.

8. Parking. Sublandlord and Subtenant acknowledge and agree that Subtenant’s
parking rights in connection with the Premises are set forth in Section 9 of the
Fourth Amendment and that no additional rights to use the Parking Facilities are
granted to Subtenant in connection with this Fifth Amendment.

9. Landlord Consent. Sublandlord’s execution of this Fifth Amendment and the
effectiveness of this Fifth Amendment are conditioned upon receipt by
Sublandlord of Landlord’s written consent executed in substantially the form
attached hereto as Exhibit B (“Landlord’s Consent”).

10. Brokerage. Sublandlord and Subtenant each warrant to the other that it has
not dealt with any broker or agent in connection with the negotiation or
execution of this Fifth Amendment other than CBRE. Subtenant shall indemnify
Sublandlord against all costs, expenses, attorneys’ fees, and other liability
for commissions or other compensation claimed by any other broker or agent
claiming the same by, through, or under Subtenant. Sublandlord shall indemnify
Subtenant against all costs, expenses, attorneys’ fees, and other liability for
commissions or other compensation claimed by any other broker or agent claiming
the same by, through, or under Sublandlord.

11. Binding Effect; Governing Law; Recitals. Except as modified hereby, the
Sublease shall remain in full effect, and the Sublease and this Fifth Amendment
shall be binding upon Sublandlord and Subtenant and their respective successors
and assigns. If any inconsistency exists or arises between the terms of this
Fifth Amendment and the terms of the

 

Page 4 of 9

--------------------------------------------------------------------------------

Sublease, the terms of this Fifth Amendment shall prevail. This Fifth Amendment
shall be governed by the laws of the State of New York. The recitals at the
beginning of this Fifth Amendment are hereby incorporated as if fully set forth
herein. Capitalized terms used herein but not defined shall have the meaning
given such terms under the Sublease.

12. Counterparts. This Fifth Amendment may be executed in multiple counterparts,
each of which shall constitute an original, with the same effect as if the
signatures thereto and hereto were upon the same instrument. If any signature to
this Fifth Amendment is delivered by facsimile transmission or by e-mail
delivery of a portable document format (.pdf or similar format) data file, then
such signature shall create a valid and binding obligation of the party
executing (or on whose behalf such signature is executed) with the same force
and effect as if such facsimile or “.pdf” signature page were an original
thereof. This Fifth Amendment shall become effective when both Sublandlord and
Subtenant have received a counterpart hereof signed by the other, subject to
receipt of Landlord’s Consent.
