2.1    Use of the Loan. The Company may use the Loan only for the purpose of funding the Project as described in the Project Plan. The Costs Schedule attached at Schedule 2 sets out how the Parties envisage the Facility Amount will be used for the Project. Any other use of the Loan is subject to the prior written consent of Wellcome.

2.2    Drawdown: In order to draw down the Loan:

(a)    the Company must provide Wellcome with the Drawdown Documents; and

(c)    Drawdowns can be made quarterly.

2.3    Facility cancellation.

(b)    If no Drawdown Notice has been received by Wellcome within six (6) months of the Effective Date, the Facility shall be cancelled unless agreed otherwise in writing by Wellcome.

2.4    Milestones and subsequent tranches of the Facility

(a)    On the achievement of any Milestone by the relevant Milestone Date, the Company shall promptly provide Wellcome with a report setting out how the Milestone was achieved (a “Milestone Report”) together with the Drawdown Documents if drawdown is required.

(b)    Within twenty (20) Business Days of receipt of the Milestone Report and the relevant Drawdown Documents, Wellcome shall confirm to the Company in writing:

(i)    whether Wellcome is satisfied, acting reasonably, that the relevant Milestone has been achieved by the relevant Milestone Date. In such circumstances, Wellcome’s confirmation shall trigger payment of the relevant tranche of the Facility to the Company in accordance with Clause 2.5;

(ii)    whether Wellcome is not satisfied, acting reasonably, that the relevant Milestone has been achieved by the relevant Milestone Date. In such circumstances, the relevant tranche of the Facility will not be paid by Wellcome to the Company (subject to the remainder of this Clause 2.4(b)(ii)) and Wellcome shall provide the Company with reasonable details of the grounds on which it has reached this decision. Wellcome may, at its sole discretion, grant the Company a reasonable period of time (“Milestone Extension”), in order to address the reasons why Wellcome has judged that a particular Milestone has not been met. Upon the expiry of a Milestone Extension, Wellcome shall, at its sole discretion, decide whether or not to pay any further tranches of the Loan to the Company, but Wellcome shall not be obliged to do so.

2.5    Payment of Facility tranches. Subject always to the satisfaction of the Loan Conditions, Wellcome shall release the relevant tranche of the Facility within twenty-five (25) Business Days of the date that Wellcome receives a Drawdown Notice. Drawdowns can be requested quarterly, up to the value of the relevant approved Milestone. Drawdowns will be capped to the total of the relevant Milestone, until, subject to Clause 2.4(b)(ii), the date that Wellcome agrees that the next relevant Milestone has been achieved.

If the Loan Conditions are not met because the contents of any Drawdown Documents are not in compliance with the terms of this Agreement, the relevant tranche of the Facility will not be released, in which case Wellcome shall provide the Company with reasonable details of the grounds on which it has reached this decision. If the Company cures the issues identified by Wellcome within a reasonable period of time, and in any event prior to the expiry of the Drawdown Period, Wellcome shall release the relevant tranche of

the Facility within fifteen (15) Business Days of confirmation that such issues have been cured. In case the Company is unable to cure the issues identified by Wellcome and Wellcome formally conveys the same to the Company, this event shall constitute an Event of Default under Clause 9.1(c).

2.6    End of Award reporting. The Company shall complete and submit an End of Award Report and Final Expenditure Report to Wellcome, within three (3) months following completion of the Project (or such other date as may be agreed by the Company and Wellcome). Wellcome will evaluate the End of Award Report and Final Expenditure Report and will notify the Company within twenty (20) Business Days of receipt whether these reports are acceptable to Wellcome, such approval not to be unreasonably withheld. If the End of Award Report or Final Expenditure Report is not acceptable to Wellcome, Wellcome shall notify the Company of its reasons at the same time, which may include that the reports (or either of them) are incomplete or insufficiently detailed.

Such withholding and payment shall fully discharge the Party making the payment and no further payment shall be required by the payor to the payee. The Party withholding or making such payment shall furnish the other Party with appropriate documents to secure application of the most favourable rate of withholding tax under applicable law.

3    INTEREST

3.1    Interest. Interest is payable on repayment of the Loan in accordance with Clause 3.2. Interest is not payable on any amount(s) of the Loan converted into Conversion Stock. On the conversion of any amount of the Loan into Conversion Stock any Accrued Interest in respect of such Conversion Amount falls away and is not repayable.

3.2    Interest calculation on repayment. Accrued Interest shall be deemed to have accrued on a daily basis (by reference to a year of three hundred and sixty-five (365) days) on the amount of the Loan from time to time outstanding at a rate of two percent (2%) per annum above the Sterling Overnight Index Average

(SONIA) from time to time, provided that at any time such rate is equal to or likely to exceed nine percent (9%), the Parties shall meet and discuss adjusting the interest rate (e.g., either by adjusting the percentage above SONIA, or setting a ceiling on the maximum applicable interest rate). Accrued Interest shall be added to the principal amount of the Loan annually on each Anniversary Date and on each Repayment Date (if the relevant Repayment Date is not an Anniversary Date).

3.3    Default interest. Where the Company fails to pay any amount due under this Agreement on the relevant due date, interest shall accrue on the overdue amount from the due date up to the date of actual payment (both before and after judgement) at a rate which is the sum of three percent (3%) per annum and the rate which would have been payable if the overdue amount had constituted a loan in an amount equal to such overdue amount on the same terms as the Loan. Any interest accruing under this Clause 3.3 shall be immediately payable by the Company on demand.

If such funding or support has not been provided by Wellcome by the expiry of such period, the Company shall be free to obtain such funding or support from elsewhere without restriction. The Company is not restricted from raising general funding for the operation of its business provided that such funds are not specifically earmarked for the Project.

15.2    If at any time the Company is seeking to obtain funding from Institutional Investors, the Company shall inform Wellcome in good time prior to entering into any term sheet and Wellcome will discuss with the Company the possibility of repayment of the Loan (and Accrued Interest if relevant) or conversion prior to completion of such investment.

18    ENTIRE AGREEMENT/VARIATIONS

18.1    This Agreement, together with the Application and any agreement entered into pursuant to the Agreement constitutes the entire agreement and understanding between the Parties relating to the matters dealt with in this Agreement and supersedes all prior discussions and agreements covering the subject matter of this Agreement.

18.2    The Agreement may only be amended by agreement of the Parties in writing.

19    ANNOUNCEMENTS

19.1    Except as set out in this Agreement or as required by law or any competent regulatory authority, including pursuant to any rule or regulation of the Securities and Exchange Commission and/or the New York Stock Exchange (or any other exchange on which the Company’s shares may be listed), no announcement concerning this Agreement or its subject matter shall be made by either Party without the prior written approval of the other Party.

19.2    Wellcome is permitted to publish a summary description of the Project including: the name of the Principal Investigator, the name of the Company, the title of the Project, the maximum amount of the Facility and the following description of the Project: “Bipolar disorder is a severe, life-long psychiatric condition associated with a high burden of disability and risk of suicide. The only approved treatments for its depressive phase (BD-D) are antipsychotic medications, which carry many side effects. As BD-D is defined by clinical phenomenology rather than by biology, successful development of new treatment options will most likely come by targeting biologically defined patient subgroups characterized by relevant pathophysiology (i.e. a precision psychiatry approach). Extensive data show neuroplasticity-related abnormalities in the brains of BD-D patients that can be clinically identified as deficits in memory, commonly seen in BD-D. A drug that enhances hippocampal neuroplasticity therefore holds promise specifically for memory-impaired BD-D patients. ALTO-100 is an orally active small molecule with a novel pro-neurogenesis/neuroplasticity mechanism of action. We have shown that MDD or PTSD patients with poor memory respond better to ALTO-100 than those with intact cognition. Here, we propose taking a precision psychiatry approach through a poor memory-stratified Phase 2b trial of ALTO-100 in BD-D, following closely the already FDA-reviewed design of an ongoing MDD Phase 2b. A successful outcome could accelerate this drug into Phase 3, potentially providing a groundbreaking new option for a highly underserved clinical population.”

19.3    Wellcome’s contribution must be acknowledged in all scientific publications concerning the Project, quoting the Award reference number 306439/Z/23/Z.

19.4    A copy of all research publications that relate to the Project must be deposited into PubMed Central (or Europe PubMed Central) upon publication in accordance with Wellcome’s open access policy set out in Schedule 8.
