purpose. Nothing in this Agreement shall be deemed as preventing either Party from seeking injunctive relief (or any other provisional remedy) from any court having jurisdiction over the Parties and the subject matter of the dispute at any time as deemed necessary to protect either Party’s name or reputation, proprietary information, trade secrets, know-how or any other right.

(c)Each of the Parties hereby irrevocably and unconditionally waives any right it may have to a trial by jury in respect of any legal action arising out of or relating to this Agreement, the other Transaction Documents or the transactions contemplated hereby or thereby.

(d)EACH PARTY IRREVOCABLY CONSENTS TO THE SERVICE OF ANY DOCUMENT OR LEGAL PROCESS IN ANY ACTION OR PROCEEDING RELATING TO ANY DISPUTE OR THE TRANSACTIONS CONTEMPLATED BY THIS AGREEMENT OR ANY OTHER TRANSACTION DOCUMENT, ON BEHALF OF ITSELF OR ITS PROPERTY, BY THE PERSONAL DELIVERY OF COPIES OF SUCH PROCESS TO SUCH PARTY IN THE MANNER PROVIDED FOR NOTICES IN SECTION 13.4. NOTHING IN THIS SECTION 10.10 SHALL AFFECT THE RIGHT OF ANY PARTY TO SERVE LEGAL PROCESS IN ANY OTHER MANNER PERMITTED BY APPLICABLE LAW.

13.15Schedules, Exhibits and Attachments.

13.16Publicity. The Parties agree that KalVista shall be permitted to make a single public announcement of the execution of this Agreement which shall be in the form of the press release attached as Exhibit H. Either Party shall have the right to disclose all or a portion of such press release at any time. Any further written publication, news release or other written public announcement relating to this Agreement, any other Transaction Document or the performance hereunder or thereunder shall require mutual agreement and first be reviewed and approved by both Parties; provided, however, that, subject to the last paragraph of Section 10.3, any disclosure which is required by Applicable Law as advised by the disclosing Party’s counsel may be made without the prior consent of the other Party, although the other Party shall be given prompt notice of any such legally required disclosure and the disclosing Party shall use commercially reasonable efforts to provide the other Party an opportunity to discuss and comment on the proposed disclosure and consider such comments in good faith before making such disclosure. Except as provided by the foregoing, neither Party shall use the name(s) of the other Party or the other Party’s personnel who have participated in this Agreement or any other Transaction Document, or any abbreviation or variant thereof, in any press release or commercial advertisement or similar material, unless such Party obtains in advance the written consent of the named Party.

Equitable Remedies; Specific Performance

13.20. The rights and remedies of the Parties shall be cumulative and not alternative, except as expressly provided in any Transaction Document. Each of the Parties agrees that this Agreement and the other Transaction Documents are intended to be legally binding and specifically enforceable pursuant to their respective terms and that the Parties would be irreparably harmed if any of the provisions of this Agreement or the other Transaction Documents are not performed in accordance with their specific terms and that monetary damages would not provide adequate remedy in such event. Accordingly, in addition to any other remedy to which a non-breaching Party may be entitled at law, a non-breaching Party shall be entitled to seek injunctive relief to prevent breaches of this Agreement or the other Transaction Documents and to specifically enforce the terms and provisions hereof and thereof. Each Party hereby irrevocably waives (a) any requirement that the other Party post a bond or other security as a condition for obtaining such relief and (b) any defenses based on adequacy of any other remedy, whether at law or in equity, that might be asserted as a bar to the remedy of specific performance of any of the terms or provisions hereof or thereof or injunctive relief in any action brought therefor by any other Party.

Closing

. Subject to the terms and conditions of this Agreement, the consummation of the transactions contemplated by this Agreement (the “Closing”) shall take place at the Washington, D.C. offices of Covington & Burling LLP, at 10:00 a.m. local time, on the third (3rd) Business Day after all of the conditions to the Closing set forth in Article VII are either satisfied or, to the extent permitted by Applicable Law, waived (other than conditions which, by their nature, are to be satisfied on the Closing Date, but subject to the satisfaction or waiver of such conditions), or at such other date, time or place as may be mutually agreed in writing by the Parties.

preceding clauses (i) through (v) (collectively, the “Transfer Activities”). KalVista and Merck shall initiate the Transfer Activities promptly after the Closing Date and as specified in the Transition Plan.

[***]Confidential Treatment Requested.

(a)Threshold. Notwithstanding anything to the contrary herein, no Merck Indemnified Party or KalVista Indemnified Party may recover Losses pursuant to Section 8.2(a) or Section 8.3(a), respectively, [***]; provided, however, that this Section 8.4(a) shall not apply to any claims for fraud or inaccuracy in or breach of the KalVista Fundamental Representations or Merck Fundamental Representations.

(b)KalVista Cap. [***] This Section 8.4(b) shall not apply to any claims for fraud.

(c)Merck Cap. [***] This Section 8.4(c) shall not apply to any claims for fraud.

(d)No Effect of Materiality. For purposes of this Article VIII, for calculating the amount of any Losses with respect to any inaccuracy in or breach of any representation or warranty, any materiality, Material Adverse Effect or other similar qualification contained in or otherwise applicable to such representation or warranty shall be disregarded.

(e)No Duplication of Recovery. Notwithstanding anything to the contrary in this Agreement, no Person shall be entitled to recover more than once for any Loss or be indemnified under this Agreement for Losses for which such Person has been otherwise compensated under any other Transaction Document.

(f)Limitation on Liability. IN NO EVENT SHALL A PARTY OR ITS AFFILIATES, OR THEIR DIRECTORS, OFFICERS, EMPLOYEES OR AGENTS BE LIABLE TO THE OTHER PARTY FOR ANY INDIRECT, INCIDENTAL, SPECIAL, EXEMPLARY OR CONSEQUENTIAL DAMAGES, WHETHER BASED UPON A CLAIM OR ACTION OF CONTRACT, WARRANTY, NEGLIGENCE, STRICT LIABILITY OR OTHER TORT, OR OTHERWISE ARISING OUT OF THIS AGREEMENT, EXCEPT WITH RESPECT TO ANY SUCH LOSSES (i) ACTUALLY AWARDED TO A THIRD PARTY IN RESPECT OF THIRD PARTY CLAIMS INDEMNIFIED HEREUNDER OR (ii) RISING OUT OF OR BASED ON A PARTY’S FRAUD OR WILLFUL MISCONDUCT OR A PARTY’S BREACH OF ITS OBLIGATIONS UNDER SECTION 6.3.

Indemnification Procedures

. The Party making a claim under this Article VIII is referred to as the “Indemnified Party” and the Party against whom such claim is asserted under this Article VIII is referred to as the “Indemnifying Party”.

(a)Third Party Claims - Notice. In the event that an Indemnified Party is seeking indemnification under this Article VIII in respect of any Action made or brought by a Third Party (a “Third Party Claim”), it shall inform the Indemnifying Party of such Third Party Claim as soon as reasonably practicable after it receives notice of such Third Party Claim (such notice, the “Claim Notice”); provided, however, the failure to inform the Indemnifying Party as soon as reasonably practicable shall not relieve the Indemnifying Party of its indemnification obligations, except and to the extent that the Indemnifying Party is actually prejudiced by reason of such failure. Such Claim Notice shall describe the Third Party Claim in reasonable detail, shall include copies of all material written evidence thereof and shall indicate the estimated amount of the Loss that has been or may be sustained by the Indemnified Party.

[***]Confidential Treatment Requested.

(b)Third Party Claims - Control. Subject to Merck’s right to control any Actions relating to the Intellectual Property Rights included in the Purchased Assets (even where KalVista is the Indemnifying Party), the Indemnifying Party shall have the right, exercisable by notice to the Indemnified Party within ten (10) Business Days after receipt of a Claim Notice, to assume direction and control of the defense, litigation, settlement, appeal or other disposition of the Third Party Claim with counsel selected by the Indemnifying Party and reasonably acceptable to the Indemnified Party; provided that the Indemnifying Party shall not be entitled to assume the defense of any Third Party Claim if such Third Party Claim (i) seeks any relief other than monetary damages, (ii) has been brought by or on behalf of any Governmental Authority or in connection with taxes or any criminal or regulatory enforcement action, (iii) is reasonably likely to result in a regulatory enforcement action by a Governmental Authority against the Indemnified Party, or (iv) relates to the intellectual property rights of the Indemnified Party (the conditions set forth in clauses (i), (ii), (iii) and (iv) above are collectively referred to as the “Defense Conditions”). Within ten (10) Business Days after the Indemnifying Party has given notice to the Indemnified Party of its exercise of its right to defend a Third Party Claim, the Indemnified Party will give notice to the Indemnifying Party of any objection thereto based upon the Defense Conditions. If the Indemnified Party reasonably so objects, the Indemnified Party will continue to defend the Third Party Claim, at the expense of the Indemnifying Party, until such time as such objection is withdrawn. If no such notice is given, or if any such objection is withdrawn, the Indemnifying Party will be entitled, at its sole cost and expense, to assume direction and control of such defense. During such time as the Indemnifying Party is controlling the defense of such Third Party Claim, the Indemnified Party will cooperate, and will cause its Affiliates and Representatives to cooperate upon request of the Indemnifying Party, in the defense or prosecution of the Third Party Claim, including by furnishing such records, information and testimony and attending such conferences, discovery proceedings, hearings, trials or appeals as may reasonably be requested by the Indemnifying Party. Notwithstanding anything to the contrary contained in this Section 8.5(b), the Indemnified Party or its Affiliates shall not be required to furnish any information or provide any testimony if such furnishing or provision would (A) violate Applicable Law or (B) jeopardize any attorney/client privilege or other established legal privilege, provided that the Indemnified Party and its Affiliates use their reasonable best efforts to furnish such information or testimony in a manner that would not violate Applicable Law or jeopardize any such legal privilege. In the event that the Defense Conditions are not satisfied or the Indemnifying Party does not notify the Indemnified Party of the Indemnifying Party’s intent to defend any Third Party Claim within ten (10) Business Days after receipt of the Claim Notice, the Indemnified Party may (without further notice to the Indemnifying Party) undertake the defense thereof with counsel of its choice and at the Indemnifying Party’s expense (including reasonable, out-of-pocket attorneys’ fees and costs and expenses of enforcement or defense). The Indemnifying Party or the Indemnified Party, as the case may be, will have the right, at its own expense, to participate in (including the right to conduct discovery, interview and examine witnesses and participate in all settlement conferences), but not control, the defense of any Third Party Claim that the other Party is defending as provided in this Agreement.

[***]Confidential Treatment Requested.

Indemnified Party will have the sole and exclusive right to settle any Third Party Claim, on such terms and conditions as it deems reasonably appropriate, to the extent such Third Party Claim involves equitable or other non-monetary relief solely against the Indemnified Party, but will not have the right to settle such Third Party Claim to the extent such Third Party Claim involves monetary damages or equitable or other non-monetary relief against the Indemnifying Party without the prior written consent of the Indemnifying Party (such consent not to be unreasonably withheld, conditioned or delayed). Neither the Indemnifying Party nor the Indemnified Party will make any admission of liability in respect of any Third Party Claim without the prior written consent of the other Party.

(d)Direct Claims. Any Action by an Indemnified Party on account of a Loss which does not result from a Third Party Claim (a “Direct Claim”) shall be asserted by the Indemnified Party by informing the Indemnifying Party of such claim as soon as reasonably practicable (an “Indemnification Demand”); provided, however, that the failure to inform the Indemnifying Party as soon as reasonably practicable shall not relieve the Indemnifying Party of its indemnification obligations, except and to the extent that the Indemnifying Party is actually prejudiced by reason of such failure. Such Indemnification Demand by the Indemnified Party shall describe the Direct Claim in reasonable detail, shall include copies of all material written evidence thereof and shall indicate the estimated amount of the Loss that has been or may be sustained by the Indemnified Party. The Indemnified Party shall allow the Indemnifying Party and its professional advisors to reasonably investigate the matter or circumstance alleged to give rise to the Direct Claim, and whether and to what extent any amount is payable in respect of the Direct Claim and the Indemnified Party shall assist the Indemnifying Party’s investigation by giving such information and assistance (including access to the Indemnified Party’s premises and personnel and the right to examine and copy any accounts, documents or records) as the Indemnifying Party or any of its professional advisors may reasonably request. Notwithstanding anything to the contrary contained in this Section 8.5(d), the Indemnified Party shall not be required to furnish any information or provide any such access if such furnishing or access would (i) violate Applicable Law or (ii) jeopardize any attorney/client privilege or other established legal privilege, provided that the Indemnified Party uses its reasonable best efforts to furnish such information in a manner that would not violate Applicable Law or jeopardize any such legal privilege. If the Indemnifying Party fails to notify the Indemnified Party within thirty (30) days following receipt of an Indemnification Demand that it disputes such Direct Claim set forth therein, the Direct Claim set forth in the Indemnification Demand shall be conclusively deemed a Loss to be indemnified under this Agreement, and the Indemnified Party shall be indemnified for the amount of the Loss stated in such Indemnification Demand on demand or, in the case of any Indemnification Demand in which the amount of such Loss (or any portion thereof) are estimated, on such later date when the amount of such Loss (or such portion thereof) becomes finally determined; provided, however, that the lack of final determination of the amount of estimated Loss (or any portion thereof) shall not limit the right of Merck to set off any claims against the Milestone Payments or the Royalty Payments in accordance with Section 8.8 in the amount of the estimated Losses set forth in the applicable Indemnification Demand. If an Indemnifying Party notifies the Indemnified Party that it disputes any such Direct Claim, the Indemnifying Party and the Indemnified Party shall attempt in good faith for a period of thirty (30) days following the Indemnified Party’s receipt of such notice to agree upon a resolution and determination of the amount of the indemnified Loss with respect to such Direct Claim. If no such agreement with respect to the Direct Claim can be reached

[***]Confidential Treatment Requested.

after such thirty (30)-day period of good faith negotiation (subject to further extensions of such time period for negotiation as mutually agreed upon in writing by the Parties), either the Indemnifying Party or the Indemnified Party may seek resolution pursuant to Section 13.14(b) of the Option Agreement (as incorporated herein pursuant to Section 10.1) for purposes of having the Direct Claim resolved in accordance with the terms of this Agreement.

Payments

. Once a Loss (a) is agreed to by the Indemnifying Party, (b) is conclusively deemed to be an indemnifiable Loss after the Indemnifying Party fails to dispute an Indemnification Demand pursuant to Section 8.5(d), or (c) is finally determined in accordance with Section 13.14(b) of the Option Agreement (as incorporated herein pursuant to Section 10.1), the Indemnifying Party shall satisfy its obligations to pay the amount of such Loss to the Indemnified Party within fifteen (15) Business Days after determination of such Loss, by wire transfer of immediately available funds.

Source of Recovery

. The Merck Indemnified Parties’ sources for payment of indemnification obligations hereunder shall be satisfied (a) first, from seeking recovery from the Escrow Amount pursuant to the Escrow Agreement, (b) second, if and to the extent a Milestone Payment or Royalty Payment is then due and payable hereunder, by set off pursuant to Section 8.8 against any such Milestone Payment or Royalty Payment that is then due and payable, or (c) third, by seeking recovery directly from KalVista or Parent. KalVista shall provide the Escrow Agent with any instructions required by the Escrow Agreement in order for the Escrow Agent to release any portion of the Escrow Amount to Merck in satisfaction of any amounts owed to any Merck Indemnified Party under this Article VIII.

Right of Set-Off

(a)Merck is expressly authorized to set off any Losses for which it is finally determined in accordance with Section 8.6 to be entitled to indemnification hereunder against any Milestone Payment or Royalty Payment that becomes due and payable under the Transaction Documents.

(b)Notwithstanding Section 6.3 and Section 6.5 of the Option Agreement, if at the time any Milestone Payment or Royalty Payment is due and payable there shall be any outstanding indemnification claim pursuant to Section 8.2 in which the amount of Losses with respect thereto shall not have been finally determined in accordance with Section 8.6, then the amount of such Milestone Payment or Royalty Payment shall be reduced by the amount of Losses that the Merck Indemnified Party reasonably estimates to be subject to such indemnification claim and that is set forth in the Claim Notice or the Indemnification Demand (taking into account the information then available to the Merck Indemnified Party). If the final amount of Losses for such indemnification claim is less than the amount by which such Milestone Payment or Royalty Payment was reduced for such claim, then Merck shall promptly deliver the difference to KalVista.

Tax Treatment of Indemnification Payments

. All indemnification payments made under this Agreement shall be treated by the Parties as an adjustment to the Purchase Price for Tax purposes, unless otherwise required by Applicable Law.

[***]Confidential Treatment Requested.

Effect of Investigation

(a). The representations, warranties and covenants of the Indemnifying Party, and the Indemnified Party’s right to indemnification with respect thereto, shall not be affected or deemed waived by reason of any investigation made by or on behalf of the Indemnified Party (including by any of its Representatives) or by reason of the fact that the Indemnified Party or any of its Representatives knew or should have known that any such representation or warranty is, was or might be inaccurate or by reason of the Indemnified Party's waiver of any condition set forth in Section 7.2 or Section 7.3, as the case may be.

Exclusive Remedies

. Subject to Section 13.19 of the Option Agreement (as incorporated herein pursuant to Section 10.1), the Parties acknowledge and agree that, following the Closing, their sole and exclusive monetary remedy with respect to any and all claims (other than claims arising from fraud on the part of a Party in connection with the transactions contemplated by this Agreement) for any breach of any representation, warranty, covenant, agreement or obligation set forth herein shall be pursuant to the indemnification provisions set forth in this Article VIII; provided that, subject to Section 8.4, the foregoing shall not limit any Party’s remedies under any other Transaction Document. Nothing in this Section 8.11 shall limit any Person's right to seek and obtain any equitable relief to which any Person shall be entitled or to seek any remedy on account of any Person’s fraudulent conduct.

Article IX
TERMINATION

Termination

. This Agreement may be terminated at any time prior to the Closing:

(a)by the mutual written consent of KalVista and Merck;

(b)by either Merck or KalVista, in the event that (i) there shall be any Applicable Law that makes consummation of the transactions contemplated by this Agreement illegal or otherwise prohibited or (ii) any Governmental Authority shall have issued a Governmental Order restraining or enjoining the transactions contemplated by this Agreement, and such Governmental Order shall have become final and non-appealable;

(c)by Merck (provided that Merck is not then in material breach of any of its representations, warranties, covenants, or other agreements contained in this Agreement), in the event of a breach by KalVista of any of its representations, warranties, covenants, or agreements contained in this Agreement if such breach (i) would give rise to the failure of a condition set forth in Section 7.1 or Section 7.2 and (ii) cannot be or has not been cured by KalVista within the earlier of (x) [***] after the delivery of written notice to KalVista of such breach and (y) the third (3rd) Business Day prior to the End Date;

(d)by KalVista (provided that KalVista is not then in material breach of any of its representations, warranties, covenants, or other agreements contained in this Agreement), in the event of a breach by Merck of any of its representations, warranties, covenants, or agreements contained in this Agreement if such breach (i) would give rise to the failure of a condition set forth in Section 7.1 or Section 7.3 and (ii) cannot be or has not been cured by Merck within the earlier of

[***]Confidential Treatment Requested.

(x) [***] after the delivery of written notice to Merck of such breach and (y) the third (3rd) Business Day prior to the End Date; or

(e)by either Merck or KalVista by providing written notice to the other at any time after the Agreement Date if the Closing has not occurred by reason of the failure of any condition set forth in Section 7.1 or Section 7.2, in the case of Merck’s termination right, or Section 7.1 or Section 7.3, in the case of KalVista’s termination right, to be satisfied prior to the date that is [***] after the Agreement Date; provided that if the condition set forth in Section 7.1(a) is the only condition in Article VII (other than any condition in Article VII that by its terms can be satisfied only at the Closing) not to be satisfied by such date, such date shall be automatically be extended until the earlier of (i) the date that is [***] after the Agreement Date and (ii) [***] following the date on which the condition set forth in Section 7.1(a) is satisfied (the applicable date, the “End Date”) provided, however, that the right to terminate this Agreement under this Section 9.1(e) shall not be available to any Party (A) whose failure to fulfill any obligation under this Agreement has been the cause of, or resulted in, the failure of the transactions contemplated by this Agreement to be consummated on or before the End Date or (B) if the other Party has commenced an action for specific performance to cause the Closing to occur pursuant to Section 13.19 of the Option Agreement (as incorporated herein pursuant to Section 10.1).

Effect of Termination

(a)In the event of the termination of this Agreement in accordance with this Article IX, this Agreement shall forthwith become void and of no further force or effect, and there shall be no Liability on the part of any Party; provided, however, that this Section 9.2 (Effect of Termination) and Article X (Miscellaneous) shall survive the termination of this Agreement and shall remain in full force and effect in accordance with their respective terms, and (b) neither KalVista nor Merck shall be relieved of any Liability arising from any fraud or willful and knowing breach by such Party of any provision of this Agreement prior to the date of such termination. A “willful and knowing breach” by a Party of a provision of this Agreement shall mean that such party knowingly undertook an action, or failed to undertake an action, with the understanding that the action, or the failure to act, was a breach by such Party of the applicable provisions of this Agreement.

(b)As soon as practicable following a termination of this Agreement in accordance with this Article IX for any reason, but in no event more than [***] after such termination, Merck and KalVista shall, to the extent practicable, withdraw all filings, applications and other submissions relating to the transactions contemplated by this Agreement filed or submitted by or on behalf of such Person, any Governmental Authority or other Person.

Notwithstanding anything to the contrary contained in this Section 8.5(b), the Indemnified Party or its Affiliates shall not be required to furnish any information or provide any testimony if such furnishing or provision would (A) violate Applicable Law or (B) jeopardize any attorney/client privilege or other established legal privilege, provided that the Indemnified Party and its Affiliates use their reasonable best efforts to furnish such information or testimony in a manner that would not violate Applicable Law or jeopardize any such legal privilege. In the event that the Defense Conditions are not satisfied or the Indemnifying Party does not notify the Indemnified Party of the Indemnifying Party’s intent to defend any Third Party Claim within ten (10) Business Days after receipt of the Claim Notice, the Indemnified Party may (without further notice to the Indemnifying Party) undertake the defense thereof with counsel of its choice and at the Indemnifying Party’s expense (including reasonable, out-of-pocket attorneys’ fees and costs and expenses of enforcement or defense). The Indemnifying Party or the Indemnified Party, as the case may be, will have the right, at its own expense, to participate in (including the right to conduct discovery, interview and examine witnesses and participate in all settlement conferences), but not control, the defense of any Third Party Claim that the other Party is defending as provided in this Agreement.

Notwithstanding anything to the contrary contained in this Section 8.5(d), the Indemnified Party shall not be required to furnish any information or provide any such access if such furnishing or access would (i) violate Applicable Law or (ii) jeopardize any attorney/client privilege or other established legal privilege, provided that the Indemnified Party uses its reasonable best efforts to furnish such information in a manner that would not violate Applicable Law or jeopardize any such legal privilege. If the Indemnifying Party fails to notify the Indemnified Party within thirty (30) days following receipt of an Indemnification Demand that it disputes such Direct Claim set forth therein, the Direct Claim set forth in the Indemnification Demand shall be conclusively deemed a Loss to be indemnified under this Agreement, and the Indemnified Party shall be indemnified for the amount of the Loss stated in such Indemnification Demand on demand or, in the case of any Indemnification Demand in which the amount of such Loss (or any portion thereof) are estimated, on such later date when the amount of such Loss (or such portion thereof) becomes finally determined; provided, however, that the lack of final determination of the amount of estimated Loss (or any portion thereof) shall not limit the right of Merck to set off any claims against the Milestone Payments or the Royalty Payments in accordance with Section 8.8 in the amount of the estimated Losses set forth in the applicable Indemnification Demand. If an Indemnifying Party notifies the Indemnified Party that it disputes any such Direct Claim, the Indemnifying Party and the Indemnified Party shall attempt in good faith for a period of thirty (30) days following the Indemnified Party’s receipt of such notice to agree upon a resolution and determination of the amount of the indemnified Loss with respect to such Direct Claim. If no such agreement with respect to the Direct Claim can be reached after such thirty (30)-day period of good faith negotiation (subject to further extensions of such time period for negotiation as mutually agreed upon in writing by the Parties), either the Indemnifying Party or the Indemnified Party may seek resolution pursuant to Section 13.14(b) of the Option Agreement (as incorporated herein pursuant to Section 10.1) for purposes of having the Direct Claim resolved in accordance with the terms of this Agreement.

KalVista Pharmaceuticals Announces Collaboration with Merck

– Covers Development of Investigational Plasma Kallikrein Inhibitors for Treatment of Diabetic Macular Edema –

– $37 Million Upfront Fee Plus Potential Milestone Payments and Sales Royalties –

– Merck Acquires 9.9% Stake in KalVista in Private Placement–

– Investigational Intravitreal DME Candidate KVD001 Phase 2 Clinical Trial Still Planned to Initiate in 2017 –

Cambridge, MA, October 10, 2017 – KalVista Pharmaceuticals, Inc. (NASDAQ: KALV), a clinical stage pharmaceutical company focused on the discovery, development, and commercialization of small molecule protease inhibitors, today announced that it has entered into a collaboration agreement with Merck, known as MSD outside the United States and Canada, through a subsidiary, for KVD001, the Company’s investigational intravitreal (IVT) injection candidate currently in development for potential treatment of diabetic macular edema (DME), as well as future oral DME compounds based upon plasma kallikrein inhibition.

“We are pleased to collaborate with Merck for the continuing development of KVD001 and future oral programs for patients with DME,” said Andrew Crockett, Chief Executive Officer of KalVista. “Plasma kallikrein inhibition is a novel approach to the treatment of DME that we believe may offer benefit to a significant number of patients, and an oral therapy particularly would represent a groundbreaking advance for treatment of this indication. We have always believed that development and commercialization of our DME therapies would require the resources of a large pharmaceutical company, and we believe Merck has the wherewithal and resources to help us advance development of our DME drug candidates. Importantly for KalVista, this collaboration also meets our strategic objectives of maintaining control of our oral HAE portfolio that we plan to develop independently. We look forward to providing more details about the Phase 2 trial for KVD001 in DME patients as the trial commences.”

Under the terms of the agreement, KalVista has granted to Merck certain rights including an option to acquire KVD001 through a period following completion of the Phase 2 proof-of-concept trial that KalVista intends to commence later this year. KalVista also has granted to Merck a similar option to acquire investigational orally delivered molecules for DME that KalVista will continue to develop as part of its ongoing research and development activities. As consideration for the agreement, Merck will pay to KalVista a $37 million non-refundable

[***]Confidential Treatment Requested.

upfront fee. KalVista is further eligible to receive payments associated with the exercise of the options by Merck and the achievement of milestones for each program that potentially total up to $715 million. KalVista also will receive tiered royalties on net sales for therapeutic candidates commercialized under this agreement. KalVista will fund and retain control over the planned Phase 2 clinical trial of KVD001 as well as development of the investigational oral DME compounds through Phase 2, unless Merck exercises its options earlier.

In addition to the collaboration, KalVista has entered into a separate $9.1 million private placement transaction with Merck under which Merck has acquired 1,070,589 shares of KalVista, representing a 9.9% ownership stake, at a price of $8.50 per share. This private placement closed concurrent with execution of the Option Agreement.

“The KalVista team has already made important progress in advancing this candidate into the clinic. At Merck, we look forward to the opportunity to apply our expertise and resources upon the achievement of proof of concept for KVD001,” said Ben Thorner, senior vice president and Head of Business Development & Licensing Merck Research Laboratories. “Merck is seeking to collaborate on the development of candidates that we believe have the potential to transform practice in areas where there is a clear need for new and improved therapeutic options.”

The agreement with Merck covers only the investigational IVT and oral plasma kallikrein inhibitor programs for DME. KalVista retains full rights to its oral hereditary angioedema (HAE) portfolio, and will have the opportunity to select and develop future oral HAE compounds. KalVista intends to continue to aggressively pursue its efforts to develop a best-in-class oral therapy for HAE, as well as additional programs focused on other proteases.

About KalVista Pharmaceuticals, Inc.

KalVista Pharmaceuticals, Inc. is a pharmaceutical company focused on the discovery, development, and commercialization of small molecule protease inhibitors for diseases with significant unmet need. The initial focus is on inhibitors of plasma kallikrein, which is an important component of the body’s inflammatory response and which, in excess, can lead to increased vascular permeability, edema and inflammation. KalVista has developed a proprietary portfolio of novel, small molecule plasma kallikrein inhibitors initially targeting hereditary angioedema (HAE) and diabetic macular edema (DME). The Company has created a structurally diverse portfolio of oral plasma kallikrein inhibitors from which it plans to select multiple drug candidates to advance into clinical trials for HAE. The first candidate of this planned portfolio, KVD818, is currently in a first-in-human study and additional program candidates are in preclinical development. KalVista’s most advanced program, an intravitreally administered plasma kallikrein inhibitor known as KVD001, has successfully completed its first‑in‑human study in patients with DME and is being prepared for Phase 2 studies in 2017.
