3.                            GSK Consents.

3.2                 Subject to the Spin-Off being completed on the terms set forth in, and the effectiveness as of the Spin-Off Date of, the TRC LLC Agreement, the Spin-Off Documents (other than the Theravance Biopharma Rights Agreement), the Theravance Agreements Amendments and the Theravance Biopharma/GSK Agreements, GSK hereby (a) consents to: (i) the assignments by Theravance to TRC of the Strategic Alliance Agreement and specified portions of the Collaboration Agreement as set forth in the TRC LLC Agreement; (ii) the contribution by Theravance of all Class B Units (as defined in the TRC LLC Agreement) of TRC and 6,375 Class C Units (as defined in the TRC LLC Agreement) of TRC to Theravance Biopharma; and (iii) the pro rata dividend of Theravance Biopharma ordinary shares to Theravance stockholders, in the case of each of clauses (i), (ii) and (iii), as set forth in, and pursuant to and in accordance with the terms of the Spin-Off Documents and the TRC LLC Agreement; and (b) agrees that the terms of the TRC LLC Agreement (including Section 12.1 of the TRC LLC Agreement) and the Spin-Off Documents do not violate the GSK Agreements, as amended by the Theravance Agreements Amendments.  This consent is limited to the terms set forth herein and the consent set forth herein shall not be deemed a consent to, waiver of, or estoppel with respect to, any subsequent or other matter.

3.3                 From and after the Spin-Off Date, without GSK’s prior written consent, neither Theravance nor Theravance Biopharma shall, and each shall cause its respective affiliates not to, directly or indirectly, waive, amend, revise or modify, or grant any consent under or with respect to, or take any other action or inaction having the effect of any of the foregoing, any of the Theravance/Theravance Biopharma Agreements or the TRC LLC Agreement, except in each case solely to reflect any Permitted Changes.  For the avoidance of doubt, the admissions of new members to TRC in connection with a Transfer (which for the avoidance of doubt includes the redomestication of a Member) permitted by and in compliance with the provisions of the TRC LLC Agreement are Permitted Changes.

3.4                 Except as expressly permitted by Section 3.2 and/or Section 3.9 of this Agreement or by Section 12.1 of the TRC LLC Agreement, neither Theravance nor Theravance Biopharma may directly or indirectly Transfer (as defined in the TRC LLC Agreement) all or any portion of its Interests with respect to the Class A Units, Class B Units or Class C Units (as each term is defined in the TRC LLC Agreement).  In addition, without the prior written consent of GSK, TRC shall not, except for the Units (as defined in the TRC LLC Agreement) authorized in accordance with Sections 3.1 and 3.2 of the TRC LLC Agreement and Transfers permitted by Article XII of the TRC LLC Agreement and Section 3.9 of this Agreement, issue, sell, deliver or transfer any Units (as defined in the TRC LLC

4

Agreement) or any other interests of any kind in TRC or any options, warrants, rights, calls, claims or other commitments (contingent or otherwise), conversion rights, rights of exchange or any other interests exchangeable for, convertible into or evidencing a right to subscribe for or purchase any Units.  Any attempted Transfer, sale, issuance or delivery in violation of this Section 3.4 will be void ab initio and be deemed a breach of this Agreement.

3.5                 Neither Theravance nor Theravance Biopharma (nor any of their respective affiliates), in their capacities as holders of Units or otherwise, shall voluntarily dissolve TRC, except for dissolutions in which all of TRC’s interests in the GSK Agreements are distributed to Theravance or an affiliate of Theravance.  Without limiting the foregoing sentence or Section 3.4 above, each of Theravance and Theravance Biopharma shall use all commercially reasonable efforts to ensure that any distribution of the assets of TRC in the event of the dissolution or winding up of TRC is in accordance with, and subject to, the GSK Agreements in all respects (including, for the avoidance of doubt, any limitations or restrictions on assignment therein).

3.6                 Each party hereto agrees that it shall not seek to indirectly accomplish that which it is not permitted to accomplish directly under this Agreement, and any such attempted circumvention will be void ab initio and be deemed a breach of this Agreement.

3.7                 The parties acknowledge and agree that the provisions in this Section 3 are a material inducement to them entering into this Agreement and the other agreements contemplated herein and, notwithstanding anything else to the contrary in the Spin-Off Documents or the TRC LLC Agreement, in the event of a conflict between this Section 3 and the Spin-Off Documents or the TRC LLC Agreement, this Section 3 shall govern as between the parties hereto.

3.8                 Except as expressly set forth herein and in the Theravance Agreements Amendments and the Extension Agreement, the Collaboration Agreement and the Strategic Alliance Agreement (as amended by the Theravance Agreements Amendments and the Extension Agreement) remain in full force and effect in accordance with their terms, and the consent set forth herein shall not operate as a consent to, waiver of, or estoppel with respect to, any subsequent or other matter thereunder.  Without limiting the generality of the foregoing but subject to Section 5 below, each of Theravance and GSK expressly agree that the provisions relating to Confidential Information set forth in Article 10 of each of the Collaboration Agreement and the Strategic Alliance Agreement shall continue to apply in accordance with their terms, and no such Confidential Information may be provided by Theravance or TRC to Theravance Biopharma in violation of such

5

Article 10.  Notwithstanding the assignment to TRC contemplated hereby and in the TRC LLC Agreement, Theravance hereby agrees that it remains fully liable for all obligations of Theravance and of TRC under the Collaboration Agreement and the Strategic Alliance Agreement and, without limiting the foregoing, fully, unconditionally and irrevocably guarantees the performance of all such obligations by TRC.

3.9                 Following the Spin-Off Date, (a) the grant of Pre-Agreed Covenants (as defined below) with respect to any monetization of any interest in any Retained Product (as defined in the TRC LLC Agreement) or any of Theravance’s and its permitted transferees’, successors’ and permitted assigns’ Class A Units or Class C Units by Theravance and its permitted transferees, successors and permitted assigns (as applicable), (b) the grant of Pre-Agreed Covenants (as defined below) with respect to any monetization of any interest in any Assigned Product (as defined in the TRC LLC Agreement) (including, without limitation, any of Theravance’s and its permitted transferees’, successors’ and permitted assigns’ Class A Units or Class C Units, but excluding any of Theravance Biopharma’s Class B Units or Class C Units) by Theravance, TRC, or their permitted transferees, successors and permitted assigns (as applicable), and (c) the grant of Defined Covenants (as defined in the TRC LLC Agreement) in connection with the monetization of any interest in any Class B Units or Class C Units by Theravance Biopharma and its permitted transferees, successors and permitted assigns (as applicable) shall not constitute a violation of the GSK Agreements.  Notwithstanding the foregoing, each of Theravance, TRC and Theravance Biopharma (on behalf of themselves and their permitted transferees, successors and permitted assigns) agrees that, as a condition to the granting of any such Pre-Agreed Covenants or such Defined Covenants: (i)  Theravance, TRC, Theravance Biopharma and/or their permitted transferees, successors or permitted assigns (as applicable) shall obtain a certification from the original third party recipient of such Pre-Agreed Covenant or Defined Covenants, as applicable, that it is not a Restricted Party (as defined below); and (ii) any notes, securities or other instruments subject to such covenants shall provide that (a) they may not be held by a Restricted Party and if, notwithstanding such prohibition, such notes, securities or other instruments come to be held by a Restricted Party, such Restricted Party shall not be entitled to enforce or vote to enforce such Pre-Agreed Covenants or Defined Covenants, (b) any holder of such notes, securities or other instruments seeking to enforce or to vote to enforce such Pre-Agreed Covenants or Defined Covenants must provide a certificate for the benefit of the issuer that such holder is not a Restricted Party, and (c) the restriction set forth in the preceding sections (a) and (b) and this section (c) may not be waived or amended.  Any notes, securities or other instruments subject to such Pre-Agreed Covenants or Defined Covenants issued in

6

physical form shall bear a legend referencing the provisions set forth in (a), (b) and (c) of the foregoing sentence.  The parties expressly agree that no inference shall be drawn as to whether any other grant of any covenants constitutes an assignment under any GSK Agreement or a “Transfer” under this Agreement or the TRC LLC Agreement from the fact of the agreements with respect to Pre-Agreed Covenants or Defined Covenants.  Without limiting the foregoing, GSK agrees that Theravance and TRC may seek GSK’s consent that granting covenants other than Pre-Agreed Covenants under this Agreement would not violate the GSK Agreements and, provided that any such grant of covenants is subject to the conditions with respect to Restricted Parties set forth in this Section 3.9, GSK will not unreasonably withhold, condition or delay such consent.  TRC is an intended third-party beneficiary of this Section 3.9.
