Re:          Initial
Public Offering 


 


Ladies
and Gentlemen:


 


This
letter (this “Letter Agreement”) is being delivered to you in accordance with the Underwriting Agreement
(the “Underwriting Agreement”) entered into or proposed to be entered into by and between Panacea Acquisition
Corp., a Delaware corporation (the “Company”), and Cowen and Company, LLC, as the representative (“Representative”)
of the several underwriters named therein (each an “Underwriter” and collectively, the “Underwriters”),
relating to an underwritten initial public offering (the “Public Offering”), of up to 14,375,000 of
the Company’s units (including up to 1,875,000 units that may be purchased to cover the Underwriters’ option to purchase
additional units, if any) (the “Units”), each comprised of one share of Class A common stock of
the Company, par value $0.0001 per share (“Class A Common Stock”), and one-third of one redeemable
warrant (each whole warrant, a “Warrant”). Each Warrant entitles the holder thereof to purchase one
share of Class A Common Stock at a price of $11.50 per share, subject to adjustment. The Units shall be sold in the Public
Offering pursuant to a registration statement on Form S-1 and prospectus (the “Prospectus”) filed by
the Company with the Securities and Exchange Commission (the “Commission”). Certain capitalized terms
used herein are defined in paragraph 11 hereof.


 


In
order to induce the Company and the Underwriters to enter into the Underwriting Agreement and to proceed with the Public Offering
and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, EcoR1 Panacea Holdings,
LLC, a Delaware limited liability company (the “Sponsor”), PA Co-Investment LLC, a Delaware limited
liability company (“Cowen Investments” and together with the Sponsor, the “Founders”),
and the other undersigned persons (each such other undersigned persons, an “Insider” and collectively,
the “Insiders”), each hereby agrees, severally but not jointly, with the Company as follows:


 


1. The
Sponsor, Cowen Investments and each Insider agree that if the Company seeks stockholder approval of a proposed Business Combination,
then in connection with such proposed Business Combination, it, he or she shall (i) vote any Shares owned by it, him or her
in favor of any proposed Business Combination (including any proposals recommended by the Company’s Board of Directors in
connection with such Business Combination) and (ii) not redeem any Shares owned by it, him or her in connection with such
stockholder approval.


 






     


     


    

 


2. The
Sponsor, Cowen Investments and each Insider hereby agrees that in the event that the Company fails to consummate a Business Combination
within 24 months from the closing of the Public Offering, or such later period approved by the Company’s stockholders in
accordance with the Company’s amended and restated certificate of incorporation, the Sponsor, Cowen Investments and each
Insider shall take all reasonable steps to cause the Company to (i) cease all operations except for the purpose of winding up,
(ii) as promptly as reasonably possible but not more than ten (10) business days thereafter, subject to lawfully available funds
therefor, redeem 100% of the shares of Class A Common Stock sold as part of the Units in the Public Offering (the “Offering
Shares”), at a per share price, payable in cash, equal to the aggregate amount then on deposit in the Trust Account,
including interest (which interest shall be net of taxes payable and less up to $100,000 of interest to pay dissolution expenses),
divided by the number of then outstanding Offering Shares, which redemption will completely extinguish all Public Stockholders’
rights as stockholders (including the right to receive further liquidation distributions, if any) and (iii) as promptly as reasonably
possible following such redemption, subject to the approval of the Company’s remaining stockholders and the Company’s
board of directors, dissolve and liquidate, subject in each case to the Company’s obligations under Delaware law to provide
for claims of creditors and the other requirements of applicable law. The Sponsor, Cowen Investments and each Insider agree to
not propose any amendment to the Company’s amended and restated certificate of incorporation (A) to modify the substance
or timing of the Company’s obligation to allow redemption in connection with the Company’s initial Business Combination
or to redeem 100% of the Offering Shares if the Company does not complete its initial Business Combination within 24 months from
the closing of the Public Offering or (B) with respect to any other provision relating to stockholders’ rights or pre-initial
Business Combination activity, unless the Company provides its Public Stockholders with the opportunity to redeem their Offering
Shares upon approval of any such amendment at a per share price, payable in cash, equal to the aggregate amount then on deposit
in the Trust Account, including interest (which interest shall be net of taxes payable), divided by the number of then outstanding
Offering Shares.


 


The
Sponsor, Cowen Investments and each Insider acknowledge that it, he or she has no right, title, interest or claim of any kind
in or to any monies held in the Trust Account or any other asset of the Company as a result of any liquidation of the Company
with respect to the Founder Shares and Private Placement Shares held by it. The Sponsor, Cowen Investments and each Insider hereby
further waive, with respect to any Shares held by it, him or her, if any, any redemption rights it, he or she may have in connection
with (x) the consummation of a Business Combination, including, without limitation, any such rights available in the context of
a stockholder vote to approve such Business Combination or in the context of a tender offer made by the Company to purchase shares
of Class A Common Stock and (y) a stockholder vote to approve an amendment to the Company’s amended and restated certificate
of incorporation (A) to modify the substance or timing of the Company’s obligation to allow redemptions in connection with
the Company’s initial Business Combination or to redeem 100% of the Offering Shares if the Company has not consummated its
initial Business Combination within 24 months from the closing of the Public Offering or (B) with respect to any other provision
relating to stockholders’ rights or pre-initial Business Combination activity (although the Sponsor and the Insiders shall
be entitled to redemption and liquidation rights with respect to any Offering Shares it or they hold if the Company fails to consummate
a Business Combination within 24 months from the date of the closing of the Public Offering).

3. Without
limiting Cowen Investments’ obligations under paragraph 7 hereof, during the period commencing on the effective date of
the Underwriting Agreement and ending 180 days after such date, Cowen Investments shall not sell, transfer, assign, pledge or
hypothecate any of its Founder Shares or Private Placement Units (or any securities underlying the Private Placement Units, including
the Private Placement Shares and Private Placement Warrants and the shares of Class A Common Stock underlying the Private Placement
Warrants), or subject any of such securities to any hedging, short sale, derivative, put, or call transaction that would result
in the effective economic disposition of such securities, except as provided in FINRA Rule 5110(g)(2), which such restrictions
shall not be subject to release or waiver, with or without the consent of the Representative, during the period commencing on
the effective date of the Underwriting Agreement and ending 180 days after such date. Notwithstanding the provisions set forth
in paragraphs 7(a) and (b) below, during the period commencing on the effective date of the Underwriting Agreement and ending
180 days after such date, the Sponsor, Cowen Investments and each Insider shall not, without the prior written consent of the
Representative, (i) offer, pledge, sell, contract to sell, sell any option or contract to purchase, purchase any option or contract
to sell, grant any option, right or warrant to purchase, or otherwise transfer or dispose of, directly or indirectly, or file
with, or submit to, the Commission a registration statement under the Securities Act of 1933, as amended (the “Securities
Act”), relating to any Units, shares of Class A Common Stock, Founder Shares, Warrants or any securities convertible
into, or exercisable, or exchangeable for, any Units, shares of Class A Common Stock, Founder Shares, or Warrants, or publicly
disclose the intention to undertake any of the foregoing, or (ii) enter into any swap or other arrangement that transfers, in
whole or in part, any of the economic consequences of ownership of any Units, shares of Class A Common Stock, Founder Shares,
or Warrants or any such other securities, whether any such transaction described in clause (i) or (ii) above is to be settled
by delivery of units or such other securities, in cash or otherwise; provided, however, that the foregoing does
not apply to the forfeiture of any Founder Shares pursuant to their terms or any transfer of Founder Shares to any current or
future independent director of the company (as long as such current or future independent director transferee is subject to this
Letter Agreement or executes an agreement substantially identical to the terms of this Letter Agreement, as applicable to directors
and officers at the time of such transfer; and as long as, to the extent any Section 16 reporting obligation is triggered as a
result of such transfer, any related Section 16 filing includes a practical explanation as to the nature of the transfer). Each
of the Insiders and the Sponsor acknowledges and agrees that, prior to the effective date of any release or waiver, of the restrictions
set forth in this paragraph 3 or paragraph 7 below, the Company may announce the impending release or waiver by press release
through a major news service at least two business days before the effective date of the release or waiver. The provisions of
this paragraph will not apply if (i) the release or waiver is effected solely to permit a transfer of securities that is not for
consideration and (ii) the transferee has agreed in writing to be bound by the same terms described in this Letter Agreement to
the extent and for the duration that such terms remain in effect at the time of the transfer.

4. In
the event of the liquidation of the Trust Account, the Sponsor (which for purposes of clarification shall not extend to any other
stockholders, members or managers of the Sponsor) agrees to indemnify and hold harmless the Company against any and all loss,
liability, claim, damage and expense whatsoever (including, but not limited to, any and all legal or other expenses reasonably
incurred in investigating, preparing or defending against any litigation, whether pending or threatened, or any claim whatsoever)
to which the Company may become subject as a result of any claim by (i) any third party (other than the Company’s independent
registered public accounting firm) for services rendered or products sold to the Company or (ii) a prospective target business
with which the Company has discussed entering into a transaction agreement (a “Target”); provided,
however, that such indemnification of the Company by the Sponsor shall apply only to the extent necessary to ensure that
such claims by a third party for services rendered (other than the Company’s independent registered public accounting firm)
or products sold to the Company or a Target do not reduce the amount of funds in the Trust Account to below (i) $10.00 per
Offering Share or (ii) such lesser amount per Offering Share held in the Trust Account as of the date of the liquidation of the
Trust Account due to reductions in the value of the trust assets as of the date of the liquidation of the Trust Account, in each
case, net of the amount of interest which may be withdrawn to pay taxes, except as to any claims by a third party who executed
a waiver of any and all rights to seek access to the Trust Account and except as to any claims under the Company’s indemnity
of the Underwriters against certain liabilities, including liabilities under the Securities Act of 1933, as amended. In the event
that any such executed waiver is deemed to be unenforceable against such third party, the Sponsor shall not be responsible to
the extent of any liability for such third party claims. The Sponsor shall have the right to defend against any such claim with
counsel of its choice reasonably satisfactory to the Company if, within 15 days following written receipt of notice of the claim
to the Sponsor, the Sponsor notifies the Company in writing that it shall undertake such defense.


 


5. (a)
To the extent that the Underwriters do not exercise their option to purchase up to an additional 1,875,000 Units within 45 days
from the date of the Prospectus (and as further described in the Prospectus), (x) the Sponsor agrees that it shall forfeit, at
no cost, a number of Founder Shares in the aggregate equal to 375,000 multiplied by a fraction, (i) the numerator of which is
1,875,000 minus the number of Units purchased by the Underwriters upon the exercise of their option to purchase additional Units
and (ii) the denominator of which is 1,875,000 and (y) Cowen Investments agrees that it shall forfeit, at no cost, a number of
Founder Shares in the aggregate equal to 93,750 multiplied by a fraction, (i) the numerator of which is 1,875,000 minus the number
of Units purchased by the Underwriters upon the exercise of their option to purchase additional Units and (ii) the denominator
of which is 1,875,000. All references in this Letter Agreement to Founder Shares of the Company being forfeited shall take effect
as a contribution of such Founder Shares to the Company’s capital as a matter of Delaware law. The forfeiture will be adjusted
to the extent that the option to purchase additional Units is not exercised in full by the Underwriters so that the number of
Founder Shares will equal an aggregate of 20.0% of the Company’s issued and outstanding Shares after the Public Offering
(not including the Private Placement Shares). The Initial Stockholders further agree that to the extent that the size of the Public
Offering is increased or decreased, the Company will effect a capitalization or stock repurchase or redemption, as applicable,
immediately prior to the consummation of the Public Offering in such amount as to maintain the number of Founder Shares at 20.0%
of the Company’s issued and outstanding Shares upon the consummation of the Public Offering (not including the Private Placement
Shares). In connection with such increase or decrease in the size of the Public Offering, then (A) the references to 1,875,000
in the numerator and denominator of the formula in the first sentence of this paragraph shall be changed to a number equal to
15.0% of the number of shares of Class A Common Stock included in the Units issued in the Public Offering, (B) the reference to
375,000 and 93,750 in the formula set forth in the first sentence of this paragraph shall be adjusted to, respectively, the total
number of Founder Shares that the Sponsor would have to return to the Company in order for the number of Founder Shares that the
Sponsor owns (together with the Insiders) to equal an aggregate of 16.0% of the Company’s issued and outstanding Shares
after the Public Offering (not including the Private Placement Shares) and the total number of Founder Shares that Cowen Investments
would have to return to the Company in order for the number of Founder Shares that Cowen Investments owns to equal an aggregate
of 4.0% of the Company’s issued and outstanding Shares after the Public Offering (not including the Private Placement Shares).

(b) If,
in connection with the closing of a Business Combination, the Sponsor agrees to forfeit any Founder Shares or Private Placement
Units (or any securities underlying the Private Placement Units) to the Company at no cost or subject its Founder Shares or Private
Placement Units (or any securities underlying the Private Placement Units) to contractual terms or restrictions, convert its Founder
Shares into other securities or contractual rights or otherwise modify the terms of its Founder Shares or Private Placement Units
(each a “Sponsor Modification”), then Cowen Investments agrees to forfeit, subject, convert or modify
its Founder Shares or Private Placement Units (or any securities underlying the Private Placement Units) on a pro rata basis and
on the same terms as the Sponsor, and hereby grants to the Company and any representative designated by the Company without further
action by Cowen Investments a limited irrevocable power of attorney to effect such forfeiture or Sponsor Modification on behalf
of Cowen Investments, which power of attorney shall be deemed to be coupled with an interest.


 


6. The
Sponsor, Cowen Investments and each Insider hereby agree and acknowledge that: (i) the Underwriters and the Company would be irreparably
injured in the event of a breach by such Sponsor, Cowen Investments or Insider of its, his or her obligations under paragraphs
1, 2, 3, 4, 5, 7(a), 7(b), and 9 of this Letter Agreement (ii) monetary damages may not be an adequate remedy for such breach
and (iii) the non-breaching party shall be entitled to seek injunctive relief, in addition to any other remedy that such party
may have in law or in equity, in the event of such breach.


 


7. (a)
The Sponsor, Cowen Investments and each Insider agree that it, he or she shall not Transfer (as defined below) any Founder Shares
(or shares of Class A Common Stock issuable upon conversion thereof) until the earlier of (A) one year after the completion of
the Company’s initial Business Combination and (B) subsequent to the Business Combination, (x) the date on which the Company
completes a liquidation, merger, stock exchange, reorganization or other similar transaction that results in all of the Public
Stockholders having the right to exchange their shares of Common Stock for cash, securities or other property or (y) if the last
reported sale price of the Class A Common Stock equals or exceeds $12.00 per share (as adjusted for stock splits, stock dividends,
reorganizations, recapitalizations and the like) for any 20 trading days within any 30-trading day period commencing at least
150 days after the Company’s initial Business Combination (the “Founder Shares Lock-Up Period”).


 


(b) The
Sponsor, Cowen Investments and each Insider agree that it, he or she shall not Transfer any Private Placement Units, including
the Private Placement Shares and one-third of one redeemable warrant (“Private Placement Warrants”)
included therein or any shares of Class A Common Stock issued or issuable upon the conversion or exercise of the Private Placement
Warrants, until 30 days after the completion of a Business Combination (the “Private Placement Units Lock-Up Period”,
together with the Founder Shares Lock-Up Period, the “Lock-Up Periods”).

Shares, Private Placement Warrants and shares of Class A Common Stock issued or issuable upon the exercise or conversion of the
Private Placement Warrants or the Founder Shares and that are held by the Sponsor, Cowen Investments or any Insider or any of
their permitted transferees (that have complied with this paragraph 7(c)), are permitted (a) to the Company’s officers or
directors, any affiliates or family members of any of the Company’s officers or directors, any members of the Founders,
or any affiliates of the Founders, (b) in the case of an individual, by gift to a member of the individual’s immediate family
or to a trust, the beneficiary of which is a member of the individual’s immediate family or an affiliate of such person,
or to a charitable organization; (c) in the case of an individual, by virtue of laws of descent and distribution upon death of
the individual; (d) in the case of an individual, pursuant to a qualified domestic relations order; (e) by private sales or transfers
made in connection with the consummation of the Company’s Business Combination at prices no greater than the price at which
the securities were originally purchased; (f) in the event of the Company’s liquidation prior to the Company’s completion
of an initial Business Combination; (g) by virtue of the laws of Delaware or the Sponsor’s limited liability company agreement,
as amended, upon dissolution of the Sponsor; or (h) in the event of the Company’s completion of a liquidation, merger, stock
exchange, reorganization or other similar transaction which results in all of the Public Stockholders having the right to exchange
their Class A Common Stock for cash, securities or other property subsequent to the Company’s completion of an initial Business
Combination; provided, however, that in the case of clauses (a) through (e), these permitted transferees must enter
into a written agreement with the Company agreeing to be bound by the transfer restrictions and other applicable restrictions
in this Letter Agreement.


 


8. The
Sponsor, Cowen Investments and each Insider represent and warrant that it, he or she has never been suspended or expelled from

Company any finder’s fee, reimbursement, consulting fee, monies in respect of any repayment of a loan or other compensation

Combination (regardless of the type of transaction that it is).
