1.2           Patent
License; Sublicense Rights; Covenant Not To Sue.


 


(a)          As
of the Effective Date, Licensor shall automatically be deemed to grant, and does hereby grant, to RPX the Patent License, which
Patent License shall include:


 


(i)       the
non-exclusive and irrevocable (except as otherwise expressly provided in Sections 1.2(f) and 1.2(g)) right of RPX to grant to each
of Apple, Blackberry, Cisco, Google, Huawei, Ericsson, Microsoft, and Sony (each an “RPX Licensee”) a non-sublicensable,
non-transferrable sublicense under the Patent License and a release from all claims for damages for past, present and future infringement
of the Patents; provided that in no event will RPX have the right to grant to Apple, Blackberry, Huawei, Ericsson, Microsoft, or
Sony the rights with respect to the Patents to the extent that such rights are duplicative of rights granted to Apple, Blackberry,
Huawei, Ericsson, Microsoft, or Sony prior to the Effective Date (by way of non-limiting example, RPX will not have the right to
grant to Huawei a sublicense under the Patent License with respect to any Patents under which Huawei has received a perpetual license
prior to the Effective Date); and


 


(ii)       the
non-exclusive and irrevocable (except as otherwise expressly provided in Sections 1.2(f) and 1.2(h)) right of RPX to grant to Juniper
a non-sublicensable, non-transferrable sublicense under the Litigation Patent License and a release from all claims for damages
for past, present and future infringement of the Litigation Patents.


 




     

     


    




 


(b)          Any
sublicense (and release) granted to an RPX Licensee pursuant to Section 1.2(a)(i) shall be deemed to be an automatic, non-sublicensable,
non-transferrable sublicense (and release) to such RPX Licensee’s Affiliates (“RPX Licensee Affiliates”),
and such RPX Licensees’ and RPX Licensee Affiliates’ direct and indirect customers, Have-Made Vendors, developers,
distributors, suppliers, other contractors, licensees, and end users (each, a “Covered Third Party”), solely
to the extent such third parties make, have made, use, have used, sell, lease, have leased, import, offer for sale, have offered
for sale, have sold, copy, develop, have developed, operate, market, have marketed, import, have imported, own, order, design,
purchase, practice, obtain, keep, acquire, receive, build, deliver, host, distribute, have distributed, provide, supply, export,
have exported, and otherwise commercially exploit or dispose of any Licensed Product and Service. For clarity, the sublicense granted
in this Section 1.2(b) shall not extend to those activities of a future RPX Licensee Affiliate that occurred prior to the RPX Licensee
Affiliate being Controlled by an RPX Licensee. Notwithstanding the foregoing, to the extent that any Entity set forth on Exhibit
G or any Affiliates thereof supply off-the-shelf hardware or components to an RPX Licensee or RPX Licensee Affiliate (an “Excluded
Supplier”), such Excluded Supplier will not be deemed a “Covered Third Party” hereunder with respect to such
off-the-shelf hardware or components supplied to an RPX Licensee or RPX Licensee Affiliate.  For the avoidance of doubt, in
no event will the foregoing limitation with respect to Excluded Suppliers affect the rights that any Entity set forth on Exhibit
G or any Affiliates thereof would otherwise receive under this Agreement as a direct or indirect customer, Have-Made Vendor,
developer, distributor, other contractor, licensee, or end user of any Licensed Product and Service.


 


(c)          Any
sublicense (and release) granted to Juniper pursuant to Section 1.2(a)(ii) shall be deemed to be an automatic, non-sublicensable,
non-transferrable sublicense (and release) to Juniper’s Affiliates, and Juniper’s and Juniper’s Affiliates’
direct and indirect customers, Have-Made Vendors, developers, distributors, suppliers, other contractors, licensees, and end users
(each, a “Limited Covered Third Party”), solely to the extent such third parties make, have made, use, have
used, sell, lease, have leased, import, offer for sale, have offered for sale, have sold, copy, develop, have developed, operate,
market, have marketed, import, have imported, own, order, design, purchase, practice, obtain, keep, acquire, receive, build, deliver,
host, distribute, have distributed, provide, supply, export, have exported, and otherwise commercially exploit or dispose of any
Litigation Licensed Product and Service. For clarity, the sublicense granted in this Section 1.2(c) shall not extend to those activities
of a future Juniper Affiliate that occurred prior to the Juniper Affiliate being Controlled by Juniper. Notwithstanding the foregoing,
to the extent that any Entity set forth on Exhibit G or any Affiliates thereof supply off-the-shelf hardware or components
to Juniper or a Juniper Affiliate (a “Limited Excluded Supplier”), such Limited Excluded Supplier will not be
deemed a “Limited Covered Third Party” hereunder with respect to such off-the-shelf hardware or components supplied
to Juniper or a Juniper Affiliate.  For the avoidance of doubt, in no event will the foregoing limitation with respect to
Limited Excluded Suppliers affect the rights that any Entity set forth on Exhibit G or any Affiliates thereof would otherwise
receive under this Agreement as a direct or indirect customer, Have-Made Vendor, developer, distributor, other contractor, licensee,
or end user of any Litigation Licensed Product and Service.


 




     

     


    

  


(d)          If
RPX grants a sublicense as described in Section 1.2(a)(i), RPX shall provide written notice to Licensor identifying the RPX Licensee
that has been granted such sublicense. Upon receipt of such written notice, Licensor shall, within five (5) business days, complete
the Release and Dismissal Obligations with respect to such RPX Licensee and its Affiliates if the RPX Licensee and/or its Affiliates
are or were Licensor Litigation Defendants.


 


(e)          If
RPX grants any sublicense as described in Section 1.2(a)(ii), RPX shall provide written notice to Licensor that RPX has granted
such sublicense. Upon receipt of such written notice, Licensor shall, within five (5) business days, complete the Limited Release
and Dismissal Obligations with respect to Juniper and its Affiliates if the Juniper and/or its Affiliates are or were Licensor
Litigation Defendants.


 


(f)          Within
five (5) business days of the Effective Date, each of the RPX Licensees, RPX Licensee Affiliates, Juniper, and Juniper Affiliates
that has filed a petition requesting inter partes re-examination (“IPR”) of any Patent with the Patent
Trial and Appeal Board of the United States Patent and Trademark Office (the “Board”) shall file a request with
the Board to request authorization to file a motion to terminate the pending IPR petitions (the “Petitions”)
and, after receiving the Board’s authorization to file a motion to terminate the Petitions, shall submit a motion to terminate,
within five (5) business days or sooner if required by the Board, and shall further file a copy of this Agreement, pursuant to
35 U.S.C. § 317 and 37 C.F.R. § 42.74 and must request that this Agreement be treated as business confidential information
to be kept separate from the files of the involved patent pursuant to 35 U.S.C. § 317(b) and 37 C.F.R. § 42.74(c), and
shall take all other necessary steps as may be required to terminate the Petitions, and to cooperate in affecting termination of
such proceedings (provided that Licensor itself takes all necessary steps as may be required to terminate the Petitions and to
cooperate in affecting termination of such proceedings); and (ii) each of the RPX Licensees, RPX Licensee Affiliates, Juniper,
and Juniper Affiliates that has asserted litigation counterclaims or declaratory judgment actions with respect to the Patents shall
agree to the Form of Dismissal and shall otherwise take all other necessary steps as may be required to dismiss such claims and
actions concomitantly with the dismissal of each applicable Licensor Litigation. In the event any RPX Licensee, RPX Licensee Affiliate,
Juniper, or Juniper Affiliate materially breaches the obligations set forth in this Section 1.2(f), Licensor may terminate the
Patent License solely with respect to such RPX Licensee, RPX Licensee Affiliate, Juniper or Juniper Affiliate (provided that Licensor
itself has not materially breached this Section 1.2(f) or otherwise materially breached this Agreement).


 


(g)          In
the event that an RPX Licensee or any of its Affiliates challenges the validity, enforceability, or patentability of any Patent
in any court or administrative agency having jurisdiction to consider the issue, Licensor may terminate the Patent License solely
with respect to such RPX Licensee and its Affiliates unless such challenge is in response to an assertion of infringement of a
Patent against any of the RPX Licensee’s or RPX Licensee Affiliate’s Licensed Products and Services or Combined Licensed
Products and Services.


 


(h)          In
the event that Juniper or any of its Affiliates challenges the validity, enforceability, or patentability of any Litigation Patent
in any court or administrative agency having jurisdiction to consider the issue, Licensor may terminate the Litigation Patent License
unless such challenge is in response to an assertion of infringement of a Litigation Patent against any of Juniper’s or Juniper’s
Affiliate’s Licensed Products and Services or Combined Licensed Products and Services.


 




     

     


    




 


1.3           Standstill.         For
the period beginning on the Effective Date and continuing for the six (6) month period thereafter (the “Standstill Period”),
the Parties hereby covenant and agree that (a) neither Licensor nor any of its Affiliates will sue or threaten to sue (or instruct,
encourage, or aid a third party to sue or threaten to sue) any of the Entities or Affiliates of such Entities set forth in a separate
agreement between the Parties (the “Standstill Recipients”) for direct or indirect infringement (including,
without limitation, inducement, or contributory infringement) under any Patent; (b) neither Licensor nor any of its Affiliates
will divest, transfer, or exclusively license any Patents during the Standstill Period; (c) neither RPX nor any RPX Affiliate
will challenge, or knowingly and intentionally assist others in challenging, the validity, enforceability, or patentability of
any Patent in any court or administrative agency having jurisdiction to consider the issue; and (d) the Parties will engage in
good faith negotiations regarding the grant of additional licenses or other rights under the Patents to the Standstill Recipients
((a), (b), (c) and (d) collectively, the “Standstill”). Notwithstanding the foregoing, the Entities listed
on Exhibit H and their Affiliates are not “Standstill Recipients” for purposes of this Agreement.


 


1.4           Divestments
of RPX Licensees and RPX Licensee Affiliates. If an RPX Licensee or any Affiliate of an RPX Licensee divests itself of (a)
Control in, or (b) all or a substantial portion of the assets of, any Affiliate, line of business, business or operating unit or
division or any other organizational component of an RPX Licensee or an RPX Licensee Affiliate (excluding any transaction wherein
a third party obtains Control of an RPX Licensee or ownership of all or substantially all of the business or assets of an RPX Licensee,
which shall be governed by Section 5.1) (any of the foregoing a “Spin-Out”), the Patent License, releases, immunities
and covenants not to sue granted herein will continue with respect to such Spin-Out’s Licensed Products and Services and
Combined Licensed Products and Services as of the date of the Spin-Out and any improvements thereto and natural growth and evolutions
thereof; provided, however, that any Entity (and any Affiliates thereof other than the Spin-Out itself) that acquires the Spin-Out

such acquisition of the Spin-Out except with respect to any Licensed Products and Services and Combined Licensed Products and Services

(and release and covenant) granted by RPX or Licensor (as applicable) in accordance with Section 1;


 


(c)          it

to sue) RPX, any RPX Affiliate, any RPX Licensee, any RPX Licensee Affiliate, or any other Entity that has been granted a sublicense
under the Patent License (including Covered Third Parties), unless the sublicense of the applicable RPX Licensee, RPX Licensee
Affiliate, or other Entity has been terminated pursuant to Sections 1.2(f) or 1.2(g), for direct or indirect infringement (including,
without limitation, inducement, or contributory infringement) under any Patent, and, except with respect to any Excluded Supplier’s
supply of off-the-shelf hardware or components to an RPX Licensee or RPX Licensee Affiliate, neither Licensor nor its Affiliates
will sue or threaten to sue (or instruct, encourage, or aid a third party to sue or threaten to sue) any such RPX Licensee’s,
or RPX Licensee Affiliate’s customers, suppliers, manufacturers or distributors for direct or indirect infringement (including,
without limitation, inducement, or contributory infringement) under any Patent, with respect to any such RPX Licensee’s,
or RPX Licensee Affiliate’s Licensed Product and Service, unless the sublicense of the applicable RPX Licensee, RPX Licensee

Section 4.          Disclaimers,
Indemnification and Releases


 


4.1           Disclaimer.
NEITHER PARTY MAKES ANY REPRESENTATION OR WARRANTY EXCEPT AS EXPRESSLY SET FORTH IN SECTIONS 2 AND 3 ABOVE, AND EACH PARTY DISCLAIMS
ALL IMPLIED WARRANTIES, INCLUDING, WITHOUT LIMITATION, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.
EXCEPT AS EXPRESSLY SET FORTH IN SECTIONS 2 AND 3, NEITHER PARTY GIVES THE OTHER PARTY ANY ASSURANCE:


 


(A) REGARDING THE PATENTABILITY
OF ANY CLAIMED INVENTION IN, OR THE VALIDITY, OF ANY PATENT, OR


 


(B) THAT THE MANUFACTURE,
USE, SALE, OFFERING FOR SALE, IMPORTATION, EXPORTATION, OR OTHER DISTRIBUTION OF ANY LICENSED PRODUCT AND SERVICE DISCLOSED AND
CLAIMED IN ANY PATENT BY ANY LICENSEE, SUBLICENSEE OR ANYONE ELSE WILL OR WILL NOT CONSTITUTE AN INFRINGEMENT OF SUCH RIGHTS OR
ANY INTELLECTUAL PROPERTY RIGHTS OF ANY OTHER PERSONS OR ENTITIES.


 


4.2           Release.


 


(a)          As
of the Effective Date, Licensor shall automatically be deemed to, and does hereby, forever waive and release all Claims, known
or unknown, that Licensor may have against RPX, any RPX Affiliate, any RPX Licensee and any RPX Licensee Affiliate. As of the date
Licensor receives written notice contemplated under Section 1.2(e), Licensor shall automatically be deemed to, and does hereby,
forever waive and release all Litigation Claims, known or unknown, that Licensor may have against Juniper or any applicable Juniper
Affiliate.


 




     

     


    




 


(b)          Licensor
understands and agrees that the releases set forth in Section 4.2(a) shall extend to any and all Claims and Litigation Claims (as
applicable) described in Section 4.2(a) of every nature and kind whatsoever, whether such Claims or Litigation Claims (as applicable)
are known or unknown, suspected or unsuspected, and any and all rights that may exist under Section 1542 of the California Civil
Code (“Section 1542”) within the scope of the release set forth in Section 4.2(a) are expressly waived. Licensor
expressly acknowledges that it has read Section 1542, which provides as follows:


 


A
general release does not extend to claims which the creditor does not know or suspect to exist in his or her favor at the time
of executing the release, which if known by him or her, must have materially affected his or her settlement with the debtor.


 


Licensor understands and agrees that Section
1542, if applicable herein, gives it the right not to release existing Claims of which it is not now aware of and does not suspect
to exist, unless it voluntarily chooses to waive this right. Even though Licensor is aware of this right, it nevertheless hereby
voluntarily waives the right described in Section 1542, and elects to assume all risks for Claims and Litigation Claims (as applicable)
with respect to the Patents and Litigation Patents (as applicable) that now exist in its favor, known or unknown, arising from
the subject matter of the release set forth in Section 4.2(a), and expressly waives any rights under any other statutes or common
law principles of similar effect. If, contrary to the specific intent of Licensor, any Claims or Litigation Claims (as applicable)
with respect to the Patents or Litigation Patents (as applicable) released under Section 4.2(a) are deemed to exist or survive
despite the releases given in Section 4.2(a) above, Licensor hereby forever, expressly and irrevocably waives entitlement to all
such released Claims and Litigation Claims (as applicable) with respect to the Patents and Litigation Patents (as applicable),
known and unknown, prior to the Effective Date, and it is expressly agreed that the provisions of Section 1542 do not apply.

5.6           Confidentiality.
Neither Party hereto shall disclose the terms of this Agreement to any third party, without the prior written consent of the other
Party. This obligation is subject to the following exceptions: (a) disclosure by the Parties and their Affiliates is permissible
if required by government or court order, discovery request, or subpoena in pending Licensor Litigations, provided that: (i) the
disclosing Party first gives the other Party prior written notice in order to enable that Party to seek a protective order or motion
to quash (or other equivalent protection), such permissible disclosure limited to the terms legally required to be disclosed, and
(ii) any such disclosure is subject to protective order, with such permissible disclosure protected under an “Outside Attorneys
Eyes Only” or higher confidentiality designation; (b) disclosure by the Parties and their Affiliates is permissible if otherwise
required by any applicable securities laws or stock exchange requirements,
provided that the Parties will use their commercially reasonable efforts to limit the disclosure of the contents of this agreement
(including but not limited to any exhibits to this Agreement) to the extent legally permissible, as determined in each Party’s
reasonable discretion; (c) the Parties and their Affiliates may disclose
this Agreement or its contents to the extent reasonably necessary, on a confidential basis, to its accountants, attorneys, and

5.7           Publicity.
RPX may issue a press release after the Effective Date subject to the prior written approval of Licensor, not to be unreasonably
withheld. Licensor may issue a press release after the Effective Date in the form approved by RPX in writing prior to the Effective
Date. Notwithstanding anything to the contrary herein, except as expressly provided in this Section 5.7, neither Party may issue
a press release or make any similar public announcement with respect to this Agreement (whether orally or in writing) that identifies
the other Party hereto or the Entities granted a sublicense by RPX under Section 1.2, unless such other Party or Entity consents
in writing to such press release or similar public announcement. In addition, in no event will the Entities granted a sublicense
by RPX under Section 1.2 of this Agreement be subject to the foregoing restrictions set forth in this Section 5.7. For the sake
of clarity, any filings made with the SEC by Licensor that contain disclosures required to be made under relevant securities laws,
including the Securities Act of 1933 or the Securities Exchange Act of 1934, each as amended, and the rules and regulations thereunder,
shall not constitute a press release or similar public announcement under this Section 5.7.


 


5.8           Entire
Agreement. This Agreement, including Exhibits A-1 through I attached hereto, embodies the entire understanding of and
agreement between the Parties with respect to the Patents and merges and supersedes all prior agreements, understandings, negotiations,
and discussions between the Parties. Neither Party shall be bound by any condition, definition, warranty, understanding or representation
with respect to the subject matter hereof other than as expressly provided herein.


 


5.9           Counterparts.
This Agreement may be executed by the Parties in one or more counterparts, each of which shall be an original and all of which
shall together constitute one and the same instrument.


 




     

     


    




 


5.10         Relationship
of the Parties. Nothing contained herein, or done in pursuance of this Agreement, will constitute the Parties entering into
a joint venture or partnership or will constitute either Party hereto being the agent for the other Party for any purpose or in
any sense whatsoever.


 


5.11         Licenses
of Intellectual Property. All rights, licenses and releases granted by Licensor directly or indirectly to RPX, RPX Affiliates,
RPX Licensees, or RPX Limited Licensees (including each such Entity’s Affiliates) are, and shall otherwise be deemed to be,
for the purpose of Section 365(n) of the United States Bankruptcy Code, as amended (the “Bankruptcy Code”),
licenses of rights to “intellectual property” as defined under Section 101 of the Bankruptcy Code. The Parties hereto
agree that RPX, RPX Affiliates, RPX Licensees or RPX Limited Licensees (including each such Entity’s Affiliates), as licensees
or sublicensees of rights granted in this Agreement, shall retain and may fully exercise all their rights and elections under the
Bankruptcy Code. The Parties hereto further agree that, in the event that any proceeding shall be instituted by or against Licensor
seeking to adjudicate it as bankrupt or insolvent, or seeking liquidation, winding up, reorganization, arrangement, adjustment,
protection, relief or composition of it or its debts under any law relating to bankruptcy, insolvency, or reorganization or relief
of debtors, or seeking an entry of an order for relief or the appointment of a receiver, trustee or other similar official for
it or any substantial part of its property or it shall take any action to authorize any of the foregoing actions, the opposite
Parties shall have the right to retain and enforce their rights under this Agreement, provided that they remain in full compliance
with the terms and conditions of this Agreement.


 


5.12         Authorship.
Neither Party shall be considered the author of this Agreement for the purpose of interpreting any provision herein.


 


5.13         Acknowledgement.
Licensor acknowledges that nothing in this Agreement shall require or shall be construed to require RPX or any RPX Affiliate to
sue or threaten to sue (or instruct, encourage, or aid a third party to sue or threaten to sue) any Entity.


 


5.14         Termination
and Survival. Those provisions that by their nature are intended to survive termination or expiration of this Agreement shall
so survive. For the avoidance of doubt, the Patent License (including the Litigation Patent License) granted by Licensor to RPX
hereunder, RPX’s right to grant sublicenses in accordance with Section 1, all sublicenses granted by RPX in accordance with
Section 1, and all releases, covenants, representations and warranties given by Licensor shall survive termination or expiration
of this Agreement.
