		7.7	Royalty Payments



 


		7.7.1	Royalty Term



 


Roche shall pay to lcagen royalties on Net Sales of Products on a Product-by-Product
and country-by-country basis during the Royalty Term. The licenses granted to Roche shall become fully paid up, irrevocable and royalty-free
on a Product-by-Product and country-by-country basis on the expiration of the Royalty Term.


 


		7.7.2	Royalty Rates



 


The following royalty rates shall apply to the respective tiers of
aggregate Calendar Year Net Sales of a Product in the Territory, on an incremental basis, as follows:

	[***]	 	[***]
	[***]	 	[***]
	[***]	 	[***]
	[***]	 	[***]
	[***]	 	[***]


 


For example, if Net Sales of a Product in the Territory, for a given
Calendar Year, are US$3,500 million, then royalties owed to lcagen on such Net Sales of such Product for that Calendar Year shall
equal US$ [***] (US$ [***]) calculated as follows: [[***]] = US$[***] royalty payment.


 


		7.7.3	Relative Commercial Value of the Product



 


lf Roche or its Affiliates intend to sell a Combination Product in
a particular country, and the Combination Product includes a Compound that is being commercialized separately from the Combination Product
in


 






    	 	19	 



     


    

 


such country, then the Net Sales to reflect the relative commercial
value contributed by the Compound to the Combination Product in such country shall be calculated by multiplying the Net Sales of such
Combination Product by the fraction A/B, where “A” is the price of the Compound included in such Combination Product when
sold separately from any other products or services included in the Combination product and “B” is the price of the Combination
Product. lf Roche or its Affiliates intend to sell a Combination Product and the Combination Product includes a Compound that is not being
commercialized separately from the Combination Product, then the Parties shall meet approximately [***] prior to the anticipated First
Commercial Sale of such Combination Product in the Territory to negotiate in good faith and agree on how to calculate the Net Sales to
reflect the relative commercial value contributed by the Compound to the Combination Product (the “Relative Commercial Value”).
lf, after such good faith negotiations not to exceed [***], the Parties cannot agree on the Relative Commercial Value, the dispute shall
be initially referred to the executive officers of the Parties in accordance with Section 18.2.


 


lf the Parties are unable to agree on the Relative Commercial Value
within [***] of such referral, then the Relative Commercial Value shall be determined by the following procedure. Roche will select one
(1) individual who would qualify as an Expert, lcagen will select (1) [***], and those [***] (the “Expert Committee”),
each with a single deciding vote. The Expert Committee will promptly hold a meeting to review the issue under review, at which it will
consider memoranda submitted by each Party at least [***] before the meeting, as well as reasonable presentations that each Party may
present at the meeting. The determination of the Expert Committee as to the issue under review will be binding on both Parties. The Parties
will share equally in the costs of the Expert Committee. Unless otherwise agreed to by the Parties, the Expert Committee may not decide
on issues outside the scope mandated under terms of this Agreement.


 


For the purpose of calculating royalties of a Product, Calendar Year
Net Sales and the royalty rates shall be subject to the following adjustments, as applicable:


 


		7.7.4	No Valid Claim or Generic Competition



 


For a given Product, if in a given country within the Territory there
is no Composition of Matter Claim that Covers such Product then the royalty payments due to lcagen based on the applicable royalty rates
pursuant to Section 7.7.2 for such Product in such country shall be reduced by [***].


 


For a given Product, if in a given country in the Territory there is
entry of a Generic Product and if in any [***] at any time after entry of a Generic Product there has been a decline of the Sales of the
applicable Product in such country greater than [***] of the level of the Sales of such Product achieved in any of the four Calendar Quarters
immediately prior to such entry, then the royalty payments due to lcagen for such Product in such country shall be reduced by [***].


 


		7.7.5	Third Party Payments



 


Roche shall be responsible for and pay or have paid any consideration
owed to any Third Party in relation to Third Party intellectual property rights necessary to make, use or sell Products. Roche shall have
the right to deduct a maximum of [***] of such consideration actually paid to a Third Party to avoid such infringement of such Third Party
intellectual property rights solely with respect to the composition of matter or methods of use for such Product by the use, having used,
making, having made, importing, having imported, exporting, having exported, marketing, having marketed, distributing, having distributed,
selling and having sold Products in the Field in the Territory from any payments otherwise due and payable by Roche to lcagen under Section 7.5,
Section 7.6 or Section 7.7; provided that such deductions shall not exceed [***] of the amounts otherwise payable to lcagen
in any Calendar Quarter with respect to such Product; and provided, further, that any amounts not deducted in any Calendar
Quarter shall be deductible against amounts due to lcagen under Section 7.5, Section 7.6 or Section 7.7 in the future Calendar
Quarters until the full amount that Roche is entitled to deduct from amounts payable to lcagen is fully deducted. lf any deduction remains
at the time of termination of this Agreement, then any such remaining deduction shall be paid by lcagen to Roche within [***] after the
effective date of termination. Each deduction under this Section 7.7.5 shall be permitted on a Product-by-Product and country-by-country

		7.7.6	Apportionment of Compulsory Sublicensee Consideration



 


Compulsory Sublicense Compensation received by the Roche Group from
a Compulsory Sublicensee during the Royalty Term shall be shared with lcagen on an equivalent profit share percentage (the “Compulsory
Profit Share Percentage”) calculated for the respective Calendar Year as follows:


 


	[***] x 	(royalties payable to lcagen for the Product in the Territory)
	(Net Sales related to the royalties payable for the Product in the Territory)


 


At the end of the Calendar Year, Roche shall pay to lcagen the Compulsory
Sublicense Compensation under a given country or region of the Territory multiplied by the Compulsory Profit Share Percentage. For clarity,
any sales or payments by Compulsory Sublicensees under a Compulsory Sublicense shall not be considered as Net Sales and shall not give
rise to any royalty payment under Section 7.7.2 of this Agreement.


 


		7.8	Disclosure of Payments



 


lcagen acknowledges that Roche may be obligated to disclose this financial
arrangement, including all fees, payments and transfers of value, as may be advisable or required under Applicable Law, including the

		8.2	Late Payment



 


Any payment under this Agreement that is not paid on or before the
date such payment is due shall bear interest, to the extent permitted by Applicable Law, at [***] percentage points above the average
one-month Euro lnterbank Offered Rate (EURlBOR), as reported by Reuters from time to time, calculated on the number of days such payment
is overdue.


 


		8.3	Method of Payment



 


Royalties on Net Sales and all other amounts payable by Roche hereunder
shall be paid by Roche in US dollars (the “Payment Currency”) to account(s) designated by lcagen.


 


		8.4	Currency Conversion



 


When calculating the Sales of any Product that occur in currencies
other than the Payment Currency, Roche shall convert the amount of such sales into Swiss Francs and then into the Payment Currency using
Roche’s then-current internal foreign currency translation method actually used on a consistent basis in preparing its audited financial
statements (at the Effective Date, YTD average rate as reported by Reuters).


 


		8.5	Blocked Currency



 


ln a given country, if proceeds related to Net Sales are received in
a local currency that cannot be removed from such country (for example due to governmental restrictions on foreign exchange trade), then
Roche may, it its discretion, notify lcagen in writing and


 


		(a)	lcagen will have the right to receive the applicable royalties of Net Sales in such country in local currency by deposit in a local
bank designated by lcagen, or



 






    	 	21	 



     


    

 


		(b)	if such local currency payment is not allowed by reason of Applicable Law or if otherwise requested by lcagen, then the royalties
related to such Net Sales in such country shall continue to be accrued and shall continue to be reported, but such royalties will not
be paid until the sales proceeds related to such Net Sales may be removed from such country. At such time as Roche, its Affiliates or
their Sublicensees, as the case may be, is able to remove the sales proceeds related to such Net Sales from such country, Roche shall
also pay such accrued royalties in Payment Currency using the actual exchange rate which is used to remove such sales proceeds from such
country.

		(b)	Net Sales in Swiss Francs;



 


		(c)	exchange rate used for the conversion of Net Sales from Swiss Francs to the Payment Currency pursuant to Section 8.4;



 


		(d)	Sales and Net Sales in the Payment Currency;



 


		(e)	royalty rate pursuant to Section 7.7.2;



 


		(f)	adjustments made pursuant to Sections 7.7.4 - 7.7.5; and



 


		(g)	total royalty payable in the Payment Currency after adjustments made pursuant to Sections 7.7.4 - 7.7.5.



 


		9.	Taxes



 


lcagen shall pay all sales, turnover, income, revenue, value added,
and other taxes levied on account of any payments made to lcagen under this Agreement.


 


To the extent permitted by applicable law, all payments to lcagen under
this Agreement shall be made by lcagen free and clear of and without deduction or withholding for any taxes. lf provision is made in law
or regulation of any country for withholding of taxes of any type, levies or other charges with respect to any royalty or other amounts
payable under this Agreement to lcagen, then Roche shall promptly pay such tax, levy or charge for and on behalf of lcagen to the proper
governmental authority, and shall promptly furnish lcagen with receipt of payment. Roche shall be entitled to deduct any such tax, levy
or charge actually paid from royalty or other payment due lcagen or be promptly reimbursed by lcagen if no further payments are due to
lcagen. Each Party agrees to reasonably assist the other Party in claiming exemption from and/or minimizing such deductions or withholdings
under double taxation or similar agreement or treaty from time to time in force.

kept. Such audit shall be limited to results in the [***] Calendar Years prior to audit notification, and if lcagen requests an audit
for a given Calendar Year, no additional audits may be conducted in the Territory for such Calendar Year unless a discrepancy exceeding
[***] percent ([***]%) of the aggregate amount of royalty payments owed with regard to the royalty statements subject to the audit has
previously been discovered. lf lcagen does not request an audit of a given Calendar Year on or before the [***] anniversary of the end
of such Calendar Year, then lcagen will be deemed to have accepted the royalty payments and reports in such Calendar Year.

lcagen and before the final audit report is issued. The final audit report shall be shared with Roche at the same time it is shared with
lcagen.


 


		10.3	Over-or Underpayment



 


lf the audit reveals an overpayment, lcagen shall reimburse Roche for
the amount of the overpayment within [***] after the issuance of the final audit report. lf the audit reveals an underpayment, Roche shall
make up such underpayment with the next royalty payment or, if no further royalty payments are owed by Roche, Roche shall reimburse lcagen
for the amount of the underpayment within [***] after the issuance of the final audit report. Roche shall pay for the audit costs if the
underpayment of Roche exceeds [***] percent ([***]%) of the aggregate amount of royalty payments owed with regard to the royalty statements
subject to the audit. Section 8.2 shall apply to this Section 10.3.

		11.7	CREATE Act



 


lt is the intention of the Parties that this Agreement is a “joint
research agreement” as that phrase is defined in 35 USC §103(c)(3).


 


		11.8	lnfringement



 


Each Party shall promptly provide written notice to the other Party
during the Agreement Term of any (i) known infringement or suspected infringement by a Third Party of any lcagen Patent Rights, or
Joint Patent Rights, or (ii) known or suspected unauthorized use or misappropriation by a Third Party of any lcagen Know-How, Roche
Know-How or Joint Know-How, and shall provide the other Party with all evidence in its possession supporting such infringement or unauthorized
use or misappropriation.


 


Within [***] after Roche provides or receives such written notice (“Decision
Period”), Roche, in its sole discretion, shall decide whether or not to initiate a suit or action in the Territory regarding
such infringement or unauthorized use or misappropriation and shall notify lcagen of its decision in writing (“Suit Notice”).


 


lf Roche decides to bring a suit or take action, once Roche provides
Suit Notice, Roche may immediately commence such suit or take such action. ln the event that Roche (i) does not in writing advise
lcagen within the Decision Period that Roche will commence suit or take action, or (ii) fails to commence suit or take action within
a reasonable time after providing Suit Notice, lcagen shall thereafter have the right (subject to Roche’s written consent, not to
be unreasonably withheld) to commence suit or take action in the Territory and shall provide written notice to Roche of any such suit
commenced or action taken by lcagen.


 


Upon written request, the Party bringing suit or taking action (“lnitiating
Party”) shall keep the other Party informed of the status of any such suit or action and shall provide the other Party with
copies, to the extent the lnitiating Party is lawfully permitted to do so, of all substantive documents or communications filed in such
suit or action. The lnitiating Party shall have the sole and exclusive right to select counsel for any such suit or action.


 


The lnitiating Party shall, except as provided below, pay all expenses
of the suit or action, including the lnitiating Party’s attorneys’ fees and court costs. Unless otherwise agreed by the Parties,
and subject to the Parties’ respective obligations under Article 13, all monies recovered upon the final judgment or settlement
of any action described in this Section 11.8 shall be used as follows:


 


		(a)	First, to reimburse the lnitiating Party for its costs and, if any remains, to the other Party for any advisory counsel fees and costs;
and



 


		(b)	Second,



 


		(i)	if a member of the Roche Group is the lnitiating Party,



 


		(A)	any remaining amount that represents compensation for lost sales, a reasonable royalty or lost profits, shall be retained by or paid
to the lnitiating Party; provided, however, any such amount (after relevant adjustment to convert to Net Sales of Products shall be subject
to the royalty obligations set forth in Section 7.7; and



 






    	 	26	 



     


    

 


		(B)	any remaining amount that represents additional damages (e.g., enhanced or punitive damages) shall be allocated to the lnitiating
Party; and



 


		(ii)	if lcagen is the lnitiating Party, the balance, if any, shall be allocated [***] percent ([***]%) to the lnitiating Party, and [***]
percent ([***]%) to the other Party.



 


lf the lnitiating Party believes it is reasonably necessary or desirable
to obtain an effective remedy, upon written request the other Party agrees to be joined as a party to the suit or action but shall be
under no obligation to participate except to the extent that such participation is required as the result of its being a named party to
the suit or action. At the lnitiating Party’s written request, the other Party shall offer reasonable assistance to the lnitiating
Party in connection therewith at no charge to the lnitiating Party except for reimbursement of reasonable out-of-pocket expenses incurred
by the other Party in rendering such assistance. The other Party shall have the right to participate and be represented in any such suit
or action by its own counsel at its own expense.


 


The lnitiating Party may settle, consent judgment or otherwise voluntarily
dispose of the suit or action (“Settlement”) without the written consent of the other Party but only if such Settlement
can be achieved without adversely affecting the other Party (including any of its Patent Rights). lf a Settlement could adversely affect
the other Party, then the written consent of the other Party would be required, which consent shall not be unreasonably withheld.


 


For any patent that is not a lcagen Patent Right, Roche, in its sole
discretion, shall decide whether or not to initiate such suit or action in the Territory. Roche shall have full discretion as to how it
wishes to handle such suit and may reach Settlement and retain all damages, settlement fees or other consideration under any terms and
conditions it desires and retain whatever. Only if a Settlement could adversely affect lcagen shall the written consent of lcagen be required,
which consent shall not be unreasonably withheld.


 


		11.9	Defense



 


lf an action for infringement is commenced against either Party, its
licensees or its sublicensees related to lcagen’s conduct of a Research Program within the scope of the relevant Research Plan or
the discovery, development, manufacture, use or sale of a Product, then Roche shall have the right (but not the obligation) to defend
such action at its own expense, and lcagen shall assist and cooperate with Roche, at Roche’s expense, to the extent necessary in
the defense of such suit. Roche shall have the right to settle the suit or consent to an adverse judgment thereto, in its sole discretion,
so long as such settlement or adverse judgment does not adversely affect the rights of lcagen and its Affiliates (including any patent
rights Controlled by any of them). Subject to Section 7.7.5, Roche shall assume full responsibility for the payment of any award
for damages, or any amount due pursuant to any settlement entered into by it with such Third Party.


 


		11.10	Common lnterest Disclosures



 


With regard to any information or opinions disclosed pursuant to this
Agreement by one Party to each other regarding intellectual property and/or technology owned by Third Parties, the Parties agree that
they have a common legal interest in determining whether, and to what extent, Third Party intellectual property rights may affect the
conduct of a Research Program and/or Compounds and/or Products, and have a further common legal interest in defending against any actual
or prospective Third Party claims based on allegations of misuse or infringement of intellectual property rights relating to the conduct
of the relevant Research Program and/or Compounds and/or Products. Accordingly, the Parties agree that all such information and materials
obtained by lcagen and Roche from each other will be used solely for purposes of the Parties’ common legal interests with respect
to the conduct of the Agreement. All information and materials will be treated as protected by the attorney-client privilege, the work
product privilege, and any other privilege or immunity that may otherwise be applicable. By sharing any such information and materials,
neither Party intends to waive or limit any privilege or immunity that may apply to the shared information and materials. Neither Party
shall have the authority to waive any privilege or immunity on behalf of the other Party without such other Party’s prior written
consent, nor shall the waiver of privilege or immunity resulting from the conduct of one Party be deemed to apply against any other Party.

		15.	Obligation Not to Disclose Confidential lnformation



 


		15.1	Non-Use and Non-Disclosure



 


During the Agreement Term and for [***] thereafter, a Receiving Party
shall (i) treat Confidential lnformation provided by Disclosing Party as it would treat its own information of a similar nature,
(ii) take all reasonable precautions not to disclose such Confidential lnformation to Third Parties, without the Disclosing Party’s
prior written consent, and (iii) not use such Confidential lnformation other than for fulfilling its obligations under this Agreement.


 


		15.2	Permitted Disclosure



 


Notwithstanding the obligation of non-use and non-disclosure set forth
in Section 15.1, the Parties recognize the need for certain exceptions to this obligation, specifically set forth below, with respect
to press releases, patent rights, publications, and certain commercial considerations and as required by Applicable Law, including the
rules and regulations pertaining to lcagen under the Securities Exchange Act of 1934, as amended.


 


		15.3	Press Releases



 


lcagen may issue a press release for each respective Research Program
announcing the existence and selected key terms of this Agreement applicable to such respective Research Program, in a form substantially
similar to the template attached as Appendix 15.3.


 


Roche shall issue press releases in accordance with its internal policy
that typically does not issue a second press release until human proof of concept has been achieved for a Compound. Roche shall provide
lcagen with a copy of any draft press release related to the activities contemplated by this Agreement at least [***] prior to its intended
publication for lcagen’s review. lcagen may provide Roche with suggested modification to the draft press release. Roche shall consider
lcagen’s suggestions in issuing its press release. No press release shall include Confidential lnformation of the other Party without
such other Party’s prior written consent.


 






    	 	30	 



     


    

 


lcagen shall only issue press releases related to the activities contemplated
by this Agreement that either (i) have been approved by Roche or (ii) are required to be issued by lcagen as a matter of law
or regulatory compliance and lcagen has a competent legal opinion to that effect. ln all circumstances, lcagen shall provide Roche with
a draft press release at least [***] prior to its intended publication for Roche’s review. During such period, Roche shall (i) approve
the draft press release and permit lcagen to issue the press release, (ii) contact lcagen to discuss modification to the draft press
release, or (iii) contact lcagen and disapprove the press release. lf Roche asks for modification, then lcagen shall either make
such modification or work with Roche to arrive at a press release that Roche approves. lf lcagen issues a press release without Roche’s
approval, then lcagen must obtain a competent legal opinion that the release was required to be issued by lcagen as a matter of law.


 


To ensure communication alignment, responses (if any) to inquiries
by media or other Third Parties after issuance of a permitted press release by lcagen (solely or jointly with Roche) shall consist solely
of the press release language or shall follow the response guidelines that may be mutually developed by the Parties. Once approved for
disclosure, any disclosure consented to in any press release or other announcement shall be deemed to be consented to in future press
releases or other announcements.


 


		15.4	Publications



 


During the Agreement Term, the following restrictions shall apply with
respect to disclosure by any Party of Confidential lnformation relating to the Product in any publication or presentation:


 


		a)	Both Parties acknowledge that it is their policy for the studies and results thereof to be registered and published in accordance
with their internal guidelines. Roche, in accordance with its internal policies and procedures, shall have the right to publish all studies,
clinical trials and results thereof on the clinical trial registries that are maintained by or on behalf of Roche provided that it does
not include any lcagen Confidential lnformation (unless required by Applicable Law or regulatory compliance). lcagen shall not publish
any studies, clinical trials or results thereof on its clinical trial registry.



 


		b)	A Party (“Publishing Party”) shall provide the other Party with a copy of any proposed publication or presentation
at least [***] prior to submission for publication so as to provide such other Party with an opportunity to recommend any changes it reasonably
believes are necessary to continue to maintain the Confidential lnformation disclosed by the other Party to the Publishing Party in accordance
with the requirements of this Agreement. The incorporation of such recommended changes shall not be unreasonably refused; and if such
other Party notifies (“Publishing Notice”) the Publishing Party in writing, within [***] after receipt of the copy
of the proposed publication or presentation, that such publication or presentation in its reasonable judgment (i) contains an invention,
solely or jointly conceived and/or reduced to practice by the other Party, for which the other Party reasonably desires to obtain patent
protection or (ii) could be expected to have a material adverse effect on the commercial value of any Confidential lnformation disclosed
by the other Party to the Publishing Party, the Publishing Party shall prevent such publication or delay such publication for a mutually
agreeable period of time. ln the case of inventions, a delay shall be for a period reasonably sufficient to permit the timely preparation
and filing of a patent application(s) on such invention, and in no event less than [***] from the date of the Publishing Notice.



 


		15.5	Commercial Considerations



 


Nothing in this Agreement shall prevent Roche or its Affiliates from
disclosing Confidential lnformation of lcagen to (i) governmental agencies to the extent required or desirable to secure government
approval for the development, manufacture or sale of Product in the Territory, (ii) Third Parties acting on behalf of Roche, to the
extent reasonably necessary for the development, manufacture or sale of Product in the Territory, provided such Third Parties are bound
to maintain the confidentiality of such Confidential lnformation of


 






    	 	31	 



     


    

 


lcagen to the same extent as the provisions contained in this Agreement,
(iii) Third Parties requesting clinical trial data information (in accordance with Roche’s then-current data sharing policy)
or (iv) Third Parties to the extent reasonably necessary to market the Product in the Territory. The Receiving Party may disclose
Confidential lnformation of the Disclosing Party to the extent that such Confidential lnformation is required to be disclosed by the Receiving
Party to comply with Applicable Law, to defend or prosecute litigation or to comply with governmental regulations, provided that the Receiving
Party provides prior written notice of such disclosure to the Disclosing Party and, to the extent practicable, takes reasonable and lawful
actions to minimize the degree of such disclosure.

Roche shall have no obligation to transfer such Pll/Samples unless necessary for the continued development of the Product, in which case
Roche shall not be obliged to transfer any Pll/Samples that Roche in good faith believes would be prohibited or would subject Roche to
potential liability by reason of Applicable Law, contractual restrictions or insufficient patient consent. lf Roche transfers any such
Pll/Samples, lcagen shall use for the sole purpose of developing and commercializing the Product, and lcagen shall be responsible for
the correct use of the Pll/Samples in line with the informed consent forms (including but not limited to potential re-consenting of the
patients at lcagen’s costs).

Ligand Announces Icagen’s Expansion of Collaboration with
Roche to Develop and Commercialize Therapies for Neurological Diseases


 


		·	Collaboration initiates second Roche program utilizing



 


		·	Icagen’s Ion Channel Drug Discovery Platform



 


SAN
DIEGO (May 29, 2020)—Ligand Pharmaceuticals Incorporated (NASDAQ: LGND) and Icagen, a Ligand Company announced today
the expansion of Icagen’s license agreement with Roche to develop and commercialize small molecule ion channel modulators for the
treatment of neurological disorders, by adding a second program to the agreement. The new program incorporates Icagen’s ion channel
technology and expertise and is directed at a specific novel ion channel target relevant to neurodegenerative disease. The new program
is in addition to on-going work on another novel CNS target.


 


“Icagen’s collaboration with Roche was a key value-driver
in the acquisition of the Icagen business, and we are very pleased to see this expansion and extension of the relationship,” said
John Higgins, Chief Executive Officer of Ligand. “This type of deal fits perfectly within the Ligand strategy to establish and leverage
partnerships with global leaders in the industry as they look to access our technology for their drug discovery and development needs.
The Icagen team has been a great addition to Ligand’s business.”


 


“We are pleased to extend and expand our collaboration with Roche
and its drug discovery team in Basel,” said Icagen Site Head Douglas Krafte, PhD. “Our initial neurology program with Roche
continues to make great progress and we hope to assist Roche in bringing multiple meaningful therapies to patients in areas of neurological
disease with major unmet needs through both our initial and this new program.”


 


Terms of Expanded Icagen and Roche Collaboration


 


Under the terms of the license agreement, Roche made a cash upfront
payment and will provide research funding to Icagen. In addition, Icagen is eligible to potentially receive development and commercial
milestone payments of up to $274 million and royalty payments should a drug be commercialized from any of the collaboration’s
programs.


 


Icagen will be responsible for most preclinical activities up to lead
optimization with both Icagen and Roche applying resources to identify candidates for entry into IND-enabling studies. Roche will be responsible
for the further development and commercialization of the program.

 “believes,” “expects,” “anticipates,” and “will,” and similar expressions, are intended
to identify forward-looking statements. These forward-looking statements include, without limitation, statements regarding: the potential
benefits of the Icagen/Roche license and collaboration agreement programs; Ligand’s belief that recent events in its partnered programs
will enhance value; whether Ligand’s pipeline will provide a source of growth and future diversified cash flow; the potential entry

Actual events or results may differ from Ligand’s expectations due to risks and uncertainties inherent in Ligand’s business,
including, without limitation: there can be no assurance that either the original or expansion Roche program with Icagen will be able
to successfully identify any desirable drug candidates or that any drug candidates developed in such programs would be clinically or commercially
successful, all of which might result in the potential milestone payments and royalties not being earned; Ligand may not receive expected
revenue from royalties, Captisol sales, contract and service revenue; the COVID-19 pandemic has disrupted Ligand’s and its partners’
business, including delaying manufacturing, pre-clinical studies and clinical trials and product sales, and impairing global economic
activity, all of which could materially and adversely impact Ligand’s results of operations and financial condition; Ligand and
its partners may not be able to timely or successfully advance any product(s) in its internal or partnered pipeline; Ligand may not
achieve its guidance for 2020; development of product candidates by Ligand partners may not be successful; Ligand may not be able to create
future revenues and cash flows by developing innovative therapeutics; results of any clinical study may not be timely, favorable or confirmed
by later studies; products under development by Ligand or its partners may not receive regulatory approval; there may not be a market
for the product(s) even if successfully developed and approved; Ligand or its partners may not be able to protect their intellectual
property and patents covering certain products and technologies may be challenged or invalidated; Ligand’s partners may terminate
any of its agreements or development or commercialization of any of its products; Ligand may not generate expected revenues under its
existing license agreements; Ligand and its partners may experience delays in the commencement, enrollment, completion or analysis of
