NOTICE OF 2021 ANNUAL AND SPECIAL MEETING OF SHAREHOLDERS AND NOTICE OF AVAILABILITY OF MEETING MATERIALS

1 Notice of Meeting

NOTICE IS HEREBY GIVEN THAT the Annual and Special Meeting of shareholders (the "Meeting") of Liminal BioSciences Inc. (the "Company" or "Liminal BioSciences") will be conducted solely via a live webcast meeting on Friday, June 4, 2021 at 10:00 a.m. (Eastern time) at https://web.lumiagm.com/404587207. The Meeting is held for the following purposes:

1 to receive the consolidated financial statements of the Company for the financial year ended December 31, 2020 and the auditor's report thereon (for details, see subsection "Financial Statements and Auditor's Report" under the "Business of the Meeting" section of the management information circular of the Company dated April 19, 2021 (the "Management Information Circular"));

2 to elect the directors for the ensuing year (for details, see subsection "Election of Directors" under the "Business of the Meeting" section of the Management Information Circular);

3 to appoint the auditors for the ensuing year and to authorize the directors to fix their remuneration (for details, see subsection "Appointment of Auditors" under the "Business of the Meeting" section of the Management Information Circular);

4 to consider, and if deemed advisable, pass a special resolution (the "Special Resolution"), the full text of which is reproduced in Schedule "E" to the Management Information Circular, amending the articles of incorporation of the Company changing the place in Canada where the registered office is situated, from the province of Québec to Ontario, effective as at the discretion of the Board (for details, see subsection "Amendment to Articles of Incorporation" under the "Business of the Meeting" section of the Management Information Circular); and

5 to transact such other business as may properly be brought before the Meeting or any reconvened meeting following its adjournment or postponement.

Shareholders are reminded to review the Management Information Circular carefully before voting because it has been prepared to help you make an informed decision.

1.1 Notice-and-Access

This year, as permitted by Canadian securities regulators, you are receiving this notification as the Company has decided to use the "notice-and-access" mechanism for delivery to the shareholders of this notice of annual and special meeting of shareholders, the Management Information Circular and other proxy-related materials (the "Meeting Materials") as well as the annual audited consolidated financial statements of the Company for the financial year ending December 31, 2020, together with the independent auditor's report thereon and related management's discussion and analysis (together, the "Financial Statements"). Notice-and-access is a set of rules that allows issuers to post electronic versions of proxy-related materials online, via SEDAR and one other website, rather than mailing paper copies of such materials to shareholders. Under notice-and-access, shareholders still receive a proxy form or voting instruction form enabling them to vote at the Company's Meeting. However, instead of a paper copy of the Meeting Materials and the Financial Statements, shareholders receive a notice which contains information on how they may access the Meeting Materials and the Financial Statements online and how to request a paper copy. The use of notice-and-access will directly benefit the Company by substantially reducing its printing and mailing costs, is more environmentally friendly as it reduces paper use and provides more timely access to materials by shareholders.

1.3 How to request a paper copy of the Meeting Materials and of the Financial Statements

1.3.1 Before the Meeting

If your name appears on a share certificate, you are considered as a "registered shareholder." You may request paper copies of the Meeting Materials and the Financial Statements at no cost to you by calling Computershare Investor Services Inc. ("Computershare") toll-free, within North America - 1-866-962-0498 or direct, from outside of North America – 514-982-8716 and entering your control number as indicated on your form of proxy.

If your shares are listed in an account statement provided to you by an intermediary, you are considered as a "non-registered shareholder." You may request paper copies of the Meeting Materials and the Financial Statements from Broadridge at no cost to you up to one year from the date the Management Information Circular or the date of the Financial Statements was filed on SEDAR through the Internet by going to www.proxyvote.com or by telephone at 1-877-907-7643 and entering the 16-digit control number located on the voting instruction form or notification letter and following the instructions provided.

Please note that you will not receive another form of proxy or voting instruction form; please retain your current one to vote your shares.

In any case, requests should be received at least five (5) business days prior to the proxy deposit date, the time which is set for June 2, 2021 at 5:00 p.m. (Eastern time) in order to receive the Meeting Materials and the Financial Statements in advance of such date and the Meeting date. To ensure receipt of the paper copy in advance of the voting deadline and Meeting date, we estimate that your request must be received no later than 5:00 p.m. (Eastern time) on May 26, 2021.

1.3.2 After the Meeting

1.4 Participating at the Meeting

The health and safety of our communities, shareholders and employees is our priority. In light of ongoing developments regarding the coronavirus (COVID-19) pandemic, the Company is holding the Meeting as a completely virtual meeting, which will be conducted via live webcast, where all shareholders regardless of geographic location and equity ownership will have an equal opportunity to participate at the Meeting and engage with directors of the Company and management as well as other shareholders. Shareholders will not be able to attend the Meeting in person. Registered shareholders and duly appointed proxyholders will be able to attend, participate and vote at the Meeting online at https://web.lumiagm.com/404587207(meeting ID: 404-587-207). Non-registered shareholders (being shareholders who hold their shares through a

Liminal BioSciences
2021 Management Information Circular	Page | 5

broker, investment dealer, bank, trust company, custodian, nominee or other intermediary) who have not duly appointed themselves as proxyholder will not be able to attend, participate or vote at the Meeting.

A shareholder who wishes to appoint a person other than the management nominees identified on the form of proxy or voting instruction form to represent him, her or it at the Meeting may do so by inserting such person's name in the blank space provided in the form of proxy or voting instruction form and following the instructions for submitting such form of proxy or voting instruction form. This must be completed prior to registering such proxyholder, which is an additional step to be completed once you have submitted your form of proxy or voting instruction form. If you wish that a person other than the management nominees identified on the form of proxy or voting instruction form attend and participate at the Meeting as your proxy and vote your shares, including if you are a non-registered shareholder and wish to appoint yourself as proxyholder to attend, participate and vote at the Meeting, you MUST register such proxyholder after having submitted your form of proxy or voting instruction form identifying such proxyholder. Failure to register the proxyholder will result in the proxyholder not receiving a Username to participate in the Meeting. Without a Username, proxyholders will not be able to attend, participate or vote at the Meeting. To register a proxyholder, shareholders MUST visit http://www.computershare.com/Liminal and provide Computershare with their proxyholder's contact information, so that Computershare may provide the proxyholder with a Username via email.

The record date for determination of shareholders entitled to receive notice of and to vote at the Meeting is April 23, 2021.

The deadline for receiving duly completed forms of proxy or voting instruction forms or a vote using the mail, the telephone or over the Internet is 2:00 p.m. (Eastern time) on June 2, 2021.

The solicitation will be made by mail but proxies may also be solicited personally or by telephone, by directors, officers or employees of the Company. The costs of this solicitation of proxies will be borne by the Company.

In this Management Information Circular, unless otherwise specified or the context otherwise indicates, all amounts are expressed in Canadian dollars; reference to the singular shall include the plural and vice versa; the masculine shall include the feminine and vice versa.

Important Information about the Meeting

The Meeting will be held as a completely virtual meeting, which will be conducted via live webcast. Shareholders will not be able to attend the Meeting in person. A summary of the information shareholders will need to attend the Meeting online is provided below.

1 Notice-and-Access

This year, as permitted by Canadian securities regulators, the Company has decided to use the "notice-and-access" mechanism for delivery to its shareholders of the Notice of Meeting, the Circular and other proxy-related materials (the "Meeting Materials") as well as the annual audited consolidated financial statements of the Company for the financial year ending December 31, 2020 ("Financial Year 2020"), together with the independent auditor's report thereon and related management's discussion and analysis (together, the "Financial Statements"). Notice-and-access is a set of rules that allows issuers to post electronic versions of proxy-related materials online, via SEDAR and one other website, rather than mailing paper copies of such materials to shareholders. Under notice-and-access, shareholders still receive a proxy form or voting instruction form enabling them to vote at the Company's Meeting. However, instead of a paper copy of the Meeting Materials and the Financial Statements, shareholders receive a notice which contains information on how they may access the Meeting Materials and the Financial Statements online and how to request a paper copy. The use of notice-and-access will directly benefit the Company by substantially reducing its printing and mailing costs, is more environmentally friendly as it reduces paper use and provides more timely access to materials by shareholders.

2 Registered Shareholders and Non-Registered Shareholders

Registered holders of common shares of the Company ("Common Shares") (referred to in this Circular as "registered shareholders") hold Common Shares registered in their names and such Common Shares are generally evidenced by a share certificate or direct registration statement.

However, most holders of Common Shares (referred to in this Circular as "Non-Registered Shareholders"), beneficially own their Common Shares through a depositary or nominee such as a trustee, financial institution or securities broker (referred to in this Circular as "intermediaries"). If your Common Shares appear on an account statement provided by your bank, broker or financial advisor, you are, in all likelihood, a Non-Registered Shareholder. Non-Registered Shareholders should carefully follow the instructions of their intermediaries to ensure that their Common Shares are voted at the Meeting in accordance with such shareholder's instructions.

3 Voting

3.1 Voting by Proxy before the Meeting

You may vote before the Meeting by completing your form of proxy or voting instruction form in accordance with the instructions provided therein. Non-Registered Shareholders should also carefully follow all instructions provided by their intermediaries to ensure that their Common Shares are voted at the Meeting.

The persons named in the form of proxy and voting instruction form, namely Bruce Pritchard and Alek Krstajic, are the Chief Executive Officer and the Chair of the board of directors of the Company, respectively. As further described herein, you may choose another person to act as your proxyholder, including someone who is not a shareholder of the Company, by inserting such person's name in the blank space provided in the form of proxy or voting instruction form. See "Appointment of a Third Party as Proxy."

On the form of proxy, you may indicate either how you want your proxyholder to vote your Common Shares, or you can let your proxyholder decide for you. If you have specified on the form of proxy how you want your Common Shares to be voted on a particular matter, then your proxyholder must vote your Common Shares accordingly. If you have not specified on the form of proxy how you want your Shares to be voted on a particular matter, then your proxyholder can vote your Common Shares as he or she sees fit.

3.2 Voting at the Meeting

Registered shareholders may vote at the Meeting by completing a ballot online during the Meeting, as further described below. See "Attending and Participating at the Meeting."

Non-Registered Shareholders who have not duly appointed themselves as proxyholder will not be able to attend, participate or vote at the Meeting. This is because the Company and its transfer agent do not have a record of the Non-Registered Shareholders of the Company, and, as a result, will have no knowledge of your shareholdings or entitlement to vote, unless you appoint yourself as proxyholder. If you are a Non-Registered Shareholder and wish to vote at the Meeting, you have to appoint yourself as proxyholder, by inserting your own name in the space provided on the voting instruction form sent to you and must follow all of the applicable instructions provided by your intermediary. See "Appointment of a Third Party as Proxy" and "Attending and Participating at the Meeting."

4 Appointment of a Third Party as Proxy

The following applies to shareholders who wish to appoint a person (a "third party proxyholder") other than the management nominees set forth in the form of proxy or voting instruction form as

	Liminal BioSciences Inc.
Page | 8	2021 Management Information Circular

proxyholder, including Non-Registered Shareholders who wish to appoint themselves as proxyholder to attend, participate or vote at the Meeting.

Shareholders who wish to appoint a third party proxyholder to attend, participate or vote at the Meeting as their proxy and vote their Common Shares MUST submit their proxy or voting instruction form (as applicable) appointing such third party proxyholder AND register the third party proxyholder, as described below. Registering your proxyholder is an additional step to be completed AFTER you have submitted your proxy or voting instruction form. Failure to register the proxyholder will result in the proxyholder not receiving a Username to attend, participate or vote at the Meeting.

• Step 1: Submit your proxy or voting instruction form: To appoint a third party proxyholder, insert such person's name in the blank space provided in the form of proxy or voting instruction form (if permitted) and follow the instructions for submitting such form of proxy or voting instruction form. This must be completed prior to registering such proxyholder, which is an additional step to be completed once you have submitted your form of proxy or voting instruction form. If you are a Non-Registered Shareholder located in the United States, you must also provide Computershare with a duly completed legal proxy if you wish to attend, participate or vote at the Meeting or, if permitted, appoint a third party as your proxyholder. See below under this section for additional details.

• Step 2: Register your proxyholder: To register a proxyholder, shareholders MUST visit http://www.computershare.com/Liminal by 2:00 p.m. (Eastern time) on June 2, 2021 and provide Computershare with the required proxyholder contact information, so that Computershare may provide the proxyholder with a Username via email. Without a Username, proxyholders will not be able to attend, participate or vote at the Meeting.

If you are a Non-Registered Shareholder and wish to attend, participate or vote at the Meeting, you have to insert your own name in the space provided on the voting instruction form sent to you by your intermediary, follow all of the applicable instructions provided by your intermediary AND register yourself as your proxyholder, as described above. By doing so, you are instructing your intermediary to appoint you as proxyholder. It is important that you comply with the signature and return instructions provided by your intermediary. Please also see further instructions below under the heading "Attending and Participating at the Meeting."

If you are a Non-Registered Shareholder located in the United States and wish to attend, participate or vote at the Meeting or, if permitted, appoint a third party as your proxyholder, in addition to the steps described above and below under "Attending and Participating at the Meeting", you must obtain a valid legal proxy from your intermediary. Follow the instructions from your intermediary included with the legal proxy form and the voting information form sent to you, or contact your intermediary to request a legal proxy form or a legal proxy if you have not received one. After obtaining a valid legal proxy from your intermediary, you must then submit such legal proxy to Computershare. Requests for registration from Non-Registered Shareholders located in the United States that wish to attend, participate or vote at the Meeting or, if permitted, appoint a third party as their proxyholder must be sent by e-mail or by courier to: http://www.computershare.com/Liminal (if by e-mail), or Computershare Investor Services Inc., 100 University Avenue, 8th Floor, Toronto, Ontario M5J 2Y1 (if by courier), and in both cases, must be labeled as "legal proxy" and received by no later than 2:00 p.m. (Eastern time) on June 2, 2021.

The Company is holding the Meeting as a completely virtual meeting, which will be conducted via live webcast. Shareholders will not be able to attend the Meeting in person.

The restated articles of incorporation of the Company provide that the board of directors of the Company (the "Board") shall be made up of a minimum of three and a maximum of fifteen directors.

Six directors will be proposed for election at the Meeting to hold office until the next annual meeting of shareholders or until their successors are elected or appointed.

All of the nominees listed herein are current directors of the Company. See Section "Nominees for Election to the Board" for additional information on each of the nominee directors.

2.1 Majority Voting Policy

The Company has a Majority Voting Policy that applies to uncontested elections whereby any nominee for election as a director at the annual meeting of shareholders, for whom the number of votes withheld exceeds the number of votes cast in his or her favor (50 % + 1 vote), will be deemed not to have received the support of shareholders, even if he or she is elected. A director elected in such circumstances must immediately tender his or her resignation as director of the Company. Each nominee for election as a director signs a conditional letter of resignation, which automatically becomes effective following an uncontested election where said nominee receives a number of votes withheld which exceeds the number of votes cast in his or her favor (50 % + 1 vote). The Board shall accept the resignation absent the exceptional circumstances expressly described in the Majority Voting Policy regarding quorum of directors for a Board meeting. In the exceptional circumstances where the Board does not accept the resignation of the director, the director(s) who tendered their resignations will not be permitted to (i) participate in any discussions, deliberations or actions by the Board with respect to his/her own resignation and (ii) participate to any Board and/or committee meetings, unless his/her presence is required to attain quorum; and such director will not be nominated for election the following year. The Board will issue a press release announcing the resignation of the director or explaining the reasons justifying its decision not to accept the resignation.

Unless instructed to withhold the vote in the accompanying form of proxy, it is the intention of the persons named therein to vote the Common Shares represented thereby "for" the election of each of the nominees listed in the Section "Nominees for Election to the Board." Management is not aware that any of such nominees would be unwilling or unable to serve as director if elected. If any nominee becomes unable to serve as a director for any reason prior to the Meeting, and if a shareholder authorizes the persons proposed as proxies in the accompanying form of proxy to act as proxy holder at the Meeting, such persons reserve the discretionary right to vote for other management nominees, unless directed to withhold from voting.

By filling in the accompanying form of proxy, shareholders may vote for all directors or choose to withhold their vote from some or all of the directors proposed for election.

3 Appointment of Auditors

The Board recommends that PricewaterhouseCoopers LLP be appointed as auditors of the Company to hold office until the next annual meeting of shareholders or until their successors are appointed and to vote to authorize the Board to fix the auditors' remuneration. PricewaterhouseCoopers LLP was first appointed as the Company's auditor at the annual and special meeting of Liminal BioSciences held on June 19, 2019.

Unless instructed to vote against in the accompanying form of proxy, it is the intention of the persons named therein to vote the Common Shares represented thereby "FOR" the reappointment of PricewaterhouseCoopers LLP, as auditors of the Company, to hold office until the next annual meeting of shareholders and to vote to authorize the Board to fix the auditors' remuneration.

4 Amendment to Articles of Incorporation

In addition to the ordinary business to be conducted at the Meeting, approval of the Company's shareholders is being sought to consider, and if deemed advisable, pass the special resolution (the full text of which is attached to this Management Information Circular as Schedule "E" (the "Special Resolution")) amending the articles of incorporation of the Company to change the province in which its registered office is situated, from the province of Québec to the province of Ontario, effective at the discretion of the Board.

To be effective, the Canada Business Corporations Act ("CBCA") requires that the Special Resolution be approved by a special resolution of the shareholders, being a majority of not less than two-thirds (2/3) of the votes cast by shareholders present in person or by proxy at the Meeting.

Management is of the opinion that the proposed amendment of the articles of incorporation of the Company would be beneficial to the Company. The Board unanimously recommends that the Company's shareholders vote "FOR" the Special Resolution (the full text of which is reproduced in Schedule "E" hereto). Unless instructed to vote against in the accompanying form of proxy, it is the intention of the persons named therein to vote the Common Shares represented thereby "FOR" the Special Resolution.

The text of the Special Resolution authorizes the Board, at its sole discretion, to revoke the Special Resolution at any time before it is acted upon without having to obtain any further approval from shareholders.

If the Special Resolution does not receive the requisite shareholder approval, the registered office of the Company will continue to be located in the Province of Québec.

5 Other Matters

Management is not aware of any matters to be brought before the Meeting other than those set forth in the Notice accompanying this Circular.

Narrative Disclosure to Summary Compensation Table

Base Salary

We aim to provide a salary established based on the level of responsibility relative to other positions in our company and relative to base salaries paid by the organizations in our peer group as well as the performance of us and of the NEOs. It is an important component of our ability to attract and retain executives who have the leadership and management skills to drive the further growth and success of our business.

Short-Term Incentive Plan

We provide our NEOs with the STIP, which aims to engage, recognize and reward their contributions to reaching our annual objectives. Having a significant portion of all executives' annual incentive determined on the basis of the same corporate performance objectives reinforces the teamwork of the members of our executive team and motivates them to achieve widespread success for the whole organization. The corporate short-term performance objectives against which our annual performance is evaluated are established each year by the HR and corporate governance committee, in conjunction with the CEO.

The STIP targets for the NEOs are reviewed regularly to ensure that they remain competitive with those of our peer group. Target incentive levels (as a percentage of base salary) for the NEOs were the following in 2020:

Name	Short-Term Incentive Target
Bruce Pritchard	50%
Patrick Sartore	50%
Murielle Lortie	50%
Kenneth Galbraith	75%

At the beginning of 2020, corporate objectives were established for the year, each objective being assigned a relative weight. The Board, with the support of the HR and corporate governance committee was responsible for determining and approving a payout factor that would recognize our performance against the corporate objectives for the year. As a result of this assessment, the payout factor for 2020 was 25%.

The resulting payout amounts are included in the Summary Compensation Table above.

Long-Term Incentives

Long-term incentive awards are designed to reward the creation of value for our shareholders while providing a vehicle to attract and retain talented and skilled executives. Under the Omnibus Incentive Plan (the summary of which is reproduced in Schedule "B" hereto), adopted in 2019 and replacing the previous Long Term Incentive Plan, or LTIP, we grant stock options to our executives to ensure alignment of their interests with those of our shareholders, by creating focus on activities and development projects which will increase share price performance over time. It is also our practice to

Liminal BioSciences
2021 Management Information Circular	Page | 23

award an initial grant of stock options to new hires to attract qualified and skilled executives. Outstanding awards granted under the previous LTIP will continue to be governed by the terms of the LTIP until such awards are exercised, expire, or are otherwise terminated or cancelled. The previous LTIP provided stock options and RSUs.

Stock options

We granted stock options in 2020 to the NEOs at a level reflecting the executive's performance and the desired positioning of total compensation versus the comparator group in accordance with our compensation policy. Additionally, in June and August 2019, we cancelled certain outstanding options that were issued to our NEOs and employees prior to June 2019, as the exercise price of these options was significantly above the market price, such that it was highly unlikely that the options would ever be exercised. In compensation for the option holders' agreement to the cancellation, they received the new options in June 2019.

Re-pricing of stock options granted in 2019

In May 2020, we reduced in the exercise price of an aggregate amount of 1,975,289 Options originally issued on June 4, 2019 and June 19, 2019 at CA$36.00 per Common Share and CA$27.00per Common Share respectively to CA$15.21 (the "2020 Re-Pricing"). This repricing was completed to maintain the incentive nature of the stock options granted previously to the key active personnel of the Company to focus on the Company's future performance.

The value of options granted or repriced in 2020 are included in the Summary Compensation Table above.

Restricted Share Units

No RSUs were granted in 2020. All outstanding RSUs vested at the end of 2020 as they met the time-vesting criteria.

Perquisites and Other Benefits

We provide our NEOs with a competitive executive benefits package which is designed to attract and retain qualified executives. This package includes a capital accumulation retirement plan, including company contributions equal to 5% of each NEO's base salary, group insurance, reimbursement of annual medical examinations and annual professional memberships.

Director Compensation Program

The following table describes the director compensation program that is currently in effect for the 12-month period starting June 20, 2019, or the 2019-2020 Mandate, and the director compensation program that was in effect for the period spanning from May 9, 2018 through June 19, 2019, or the 2018-2019 Mandate. Due to the fact that our annual meeting of shareholders is usually held in May of each year and that the 2019 Meeting was exceptionally postponed to June 19, 2019 due to the Restructuring Transactions, an additional cash retainer representing approximately 11% of the compensation received by each director during the 2018 Financial Year was approved to compensate the directors for the additional month. Cash retainers are paid on a quarterly basis and no attendance fee is paid to the members for attending the meetings of our Board and meetings of our standing committees. Our minimum director shareholding policy was terminated on May 7, 2019.

Statement of Corporate Governance Practices

Compliance with corporate governance guidelines is a fundamental element of the manner in which the Company operates its business and seeks to enhance shareholder value. The Board is committed to high standards of corporate governance practices. Its practices are in line with those of similar Canadian companies in its sector of activity and are reviewed by the HR & Corporate Governance Committee, which makes recommendations to the Board as appropriate. The Board is of the opinion that these practices essentially comply with applicable corporate governance guidelines and ensure transparency and effective governance to the Company.

1 Board

1.1 Board Mandate

The Board is responsible for the stewardship and strategic direction of the Company. It does not actively manage but rather supervises the management of the Company's business and affairs, to ensure a consistent focus on increasing shareholder value. In exercising their powers and discharging their duties, the directors shall (a) act honestly and in good faith with a view to the best interests of the Company; and (b) exercise the care, diligence and skill that a reasonably prudent person would exercise in comparable circumstances.

To better discharge its responsibilities, the Board has established the two following standing committees: the Audit, Risk and Finance Committee and the HR & Corporate Governance Committee (collectively the "Standing Committees").

The responsibilities of the Board are fully described in the Board mandate attached as Schedule "A" to this Circular.

1.2 Independence

The Board determines the directors' independence according to Regulation 58-101 respecting disclosure of corporate governance practices as well as Regulation 52-110 respecting audit committees. Of the six nominees for election to the Board, four directors are independent being Prof. Simon Best, Neil A. Klompas, Alek Krstajic and Timothy S. Wach. The two non-independent directors are Dr. Gary Bridger and Mr. Eugene Siklos, for the following reasons:

o Dr. Gary Bridger entered into a consultancy agreement with Liminal BioSciences Limited, an indirect wholly owned subsidiary of the Company, in October 2019 as amended from time to time. Dr. Bridger is acting as Strategic Scientific Advisor to the Company.

o Mr. Eugene Siklos was designated by Structured Alpha LP ("SALP") to sit on the Board pursuant to an agreement related to the Restructuring Transaction (as defined below), which entitles SALP to designate two persons for election to the Company's Board.

While Mr. Alek Krstajic was also designated by SALP to sit on the Board, the Board determined that Mr. Krstajic is independent.

On an annual basis or as circumstance dictates, each director has to declare whether he is independent, and all such declarations are reviewed by the HR & Corporate Governance Committee, which then makes recommendations to the Board in respect of the Board's determination on the independence of the directors.

1.3 Chair of the Board & Lead Independent Director

Prof. Simon Best was appointed as Lead Independent Director on April 23, 2019 to ensure the effectiveness of the Board and that the Board functions with appropriate independence. Following the resignation of the Chair of the Board, Mr. Stefan Clulow, on September 1, 2020, Mr. Alek Krstajic was

Liminal BioSciences
2021 Management Information Circular	Page | 31

appointed Chair of the Board. Although Mr. Krstajic is an independent member, Prof. Best continued to fulfill his role as Lead Independent Director.

1.4 Directors Serving Together

For 2020, no directors of the Company served together on any other public company board.

1.5 Meetings

The Board holds regularly-scheduled meetings, special meetings and unofficial meetings to review specific matters when needed. Special meetings are held by the Board to discuss and act on matters that need attention before the following regular meeting is held or that requires additional time, such as financings, material transactions or other business concerns arising throughout the year. The number of meetings of the Board and its committees held during 2020 and members' attendance at these meetings is provided in the section "Nominees for Election to the Board."

1.6 Sessions without Management

As further described in the Board mandate (attached as Schedule "A" hereto), the directors also hold meetings without the presence of management at the end of each regularly scheduled Board or Standing Committee meeting or at other specified times during the year ("in-camera session(s)"). The directors may have in-camera session at the end of a special meeting as well, if necessary. These sessions are chaired by the Chair of the Board or the Lead Independent Director as deemed appropriate in the circumstances. There were three in-camera sessions held by the non-executive directors during the regularly scheduled meetings held during in 2020.

1.7 Sessions without Non-Independent Directors

The independent directors do not hold regularly scheduled meetings at which non-independent directors and members of management are not in attendance. Where matters discussed may involve persons having a conflict of interest or potential conflict of interest, that person may not participate in or be permitted to hear the discussion of the matter at any meeting of directors except to disclose material facts and respond to questions. A director having a conflict of interest or potential conflict of interest will be counted in determining the presence of a quorum for purposes of the vote as per the Company's articles of incorporation but will not vote on any resolution to approve such matter when the vote is taken. On occasions where it will be considered advisable, the Company's independent directors may hold meetings at which non-independent directors and members of management are not in attendance. The independent directors are able to exercise their responsibilities for independent oversight of management by virtue of forming a majority of the Board. During 2020, the independent members held one in-camera sessions during a regular Board meeting.

Board / Committees	Number of Meetings held during the 2020		Number of In- Camera Sessions(1) held during the 2020
	Regular	Special
Board	4(1)	2	3
Audit, Risk and Finance Committee	4	-	4
HR & Corporate Governance Committee(2)	4	-	3
Science and Technology Committee(4)	2	-	-

(1) In-camera sessions without management.

(2) Consists of three regular meetings and one strategic planning session. In addition, the Board holds call updates on a regular basis between regular Board meetings.

Director Tenure

The Company has not instigated a board tenure policy because the Company determined that it was not appropriate in the context of the Company, notably given, as illustrated below, the average tenure of the director nominees standing for election to the Board is 1.5 years.

Nomination of Directors

All directors may submit a list of candidates for nomination as directors to the HR & Corporate Governance Committee of the Board. Its powers in relation to new candidates for board nomination are further described in the written mandate of the HR & Corporate Governance Committee, available on the Company's website at www.liminalbiosciences.com.

If a candidacy is endorsed by the HR & Corporate Governance Committee, said nominee is submitted to the Board. The size of the Board is considered, in conjunction with the diversity of background, experience and qualifications of the directors in order to ensure that the Board functions effectively. To encourage an objective nominating process, the HR & Corporate Governance Committee seeks the input of other directors and senior management on new nominees to the Board and reviews potential candidates in light of board effectiveness assessment results.

5 Diversity

5.1 Board and Senior Management

The Company believes that drawing from a broad range and variety of perspectives is beneficial to the Company's success and helps it achieve its objectives in terms of efficiency for the benefit of its shareholders. Therefore, the Company is committed to increasing the range and variety of perspectives of its directors and senior management over time and, as such, supports initiatives aimed at identifying candidates with a broad range and variety of skills, qualifications, capabilities, talents, insights and professional and life experiences. The Company has not adopted a written diversity policy or target quota relating to the identification and nomination of directors and members of senior management. Diversity encompasses gender, age, experience, education, ethnicity, religious and cultural backgrounds as well as other dimensions such as lifestyle choices and family responsibilities (the "Designated Groups"). The Company focuses on factors such as skills, qualifications, capabilities, insights, talents, personal attributes and professional and life experiences in the director and senior management identification and selection process. Recommendations for election and appointment are made on merit, in light of the skills, experience, independence and knowledge that the Company requires to be most effective with regards to the Company's current and future plans and objectives, as well as anticipated regulatory and market developments. The Company must retain the flexibility to add qualified directors and senior management. While consideration of the number of individuals from Designated Groups who are members of the Board and members of senior management will continue to be a component of the selection process, the necessity of obtaining the right synergy and balance among directors and senior management so as to optimize the Company's ability to meet the challenges it faces is paramount.

Although there are currently no women among the Board (0%), the Company has always encouraged the representation of women on the Board. In the last seven years, the Company has had between one and three women on its Board. There are currently three women among the six senior executive officers of the Company (50%) and no less than 15 women hold a leadership position, including 8 directors, one associate director and 6 senior directors, which represents 71% of our senior leadership, assuming management responsibilities. Furthermore, we are actively engaged in discussions with potential female candidates whom we are planning on adding to the slate of nominees for election to the Board next year.

The Board is committed to equality of opportunity and to the recruitment, retention, development and promotion of qualified female candidates among its workforce, including at the highest level. In that respect, the Company has adopted an Equal Opportunities Policy by virtue of which the Company is committed to and supports the principle of equal opportunities in employment.

There are at present no Aboriginal peoples, persons with disabilities or members of visible minorities as members of the Board or senior management of the Company (0%).

5.2 Equal Opportunities Policy

The Company is committed to and supports the principle of equal opportunities in employment. The Company opposes to all forms of unlawful or unfair direct or indirect discrimination on the grounds of sex, ethnic or national origins, religion or political beliefs, disability, marital status, age and sexual orientation. The Company believes that it is in the best interest of the Company and all those who work for the Company to ensure that the talents and skills of people throughout the community are considered when employment opportunities arise.

The Company takes every step to ensure that individuals are treated equally and fairly, and decisions on recruitment and selection, training, secondment, promotion, career development and employee relations are taken solely on job-related criteria.

6 Succession Planning

The succession planning the Company is currently developing aims to ensure that there is a pipeline of leaders in the organization to drive both short-term and long-term performance and the right talent in the right roles to execute on the Company's business strategy. While the Company's succession planning used to focus more on emergency planning in case of unforeseen circumstances, such as the departure of an officer in a key leadership role, the efforts have been recently focused on developing a new succession planning program which would identify and develop key talent at the executive level in a timely manner, analyze the succession pipeline from an expertise and diversity perspective and initiate action plans to address actual or future potential gaps. The succession planning of the Company is intrinsically a continuous and evolving process.

7 Code of Ethics and Business Conduct

The Board has adopted a Code of Ethics and Business Conduct (the "Code") applicable to all directors, officers, employees and consultants of the Company and members of its group. The Code is available on request to the Corporate Secretary of the Company at its principal business office and is posted on the Company's website at www.liminalbiosciences.com as well as under the Company's profile on SEDAR at www.sedar.com and on EDGAR at www.sec.gov. The Board has the overall responsibility to monitor compliance with the Code. It generally outlines standards of conduct that must be met in carrying out one's functions, including in relation to (i) general conduct and behavior (loyalty, ethics and respectful behavior), (ii) directors' fiduciary duties, (iii) the integrity of books and records, (iv) conflict of interest principles and procedures, (v) harassment and discrimination, (vi) compliance with laws, rules and regulations including the Foreign Corrupt Practices Act, (vii) donations and contributions, (viii) the protection of intellectual property, (ix) social networks, (x) our compliance program, (xi) complaints procedures and reporting code violations, (xii) sanctions and consequences of departures from the Code, and (xiii) monitoring and waivers.

The Code contains standards of conduct to avoid or properly declare conflicts of interest. In addition, in the event that a director may have a material interest in transactions and agreements, such director is expected to declare his/her interest and otherwise act as prescribed by the CBCA, and as circumstances warrant, to abstain from voting on the approval of such transactions and agreements. The Audit, Risk and Finance Committee and the HR & Corporate Governance Committee may grant waivers of provisions of the Code to directors and senior officers, while certain members of management may grant waivers to employees. The Code is supplemented by a complaint reporting policy and a whistleblowing policy, pursuant to which persons in charge of the administration of the policy report annually to the Chair of the Audit, Risk and Finance Committee on complaints relating to accounting, audit and internal control matters and to the Chair of the HR & Corporate Governance Committee on complaints relating to other matters. During 2020, no complaints related to the Code were received, and there were no material change reports filed that pertain to any conduct of a director or executive officer that constitutes a departure from the Code.

8 Shareholder Proposals

The CBCA provides, in effect, that a registered holder or non-registered holder of Common Shares entitled to vote at an annual meeting of the Company may submit to the Company notice of any matter that the person proposes to raise at the Meeting (the "Proposal") and discuss at the Meeting any matter in respect of which the person would have been entitled to submit a Proposal. The CBCA further provides, in effect, that the Company must set out the Proposal in its management information circular along with, if so requested by the person who makes the Proposal, a statement in support of the Proposal by such person. However, the Company will not be required to set out the Proposal in its management information circular or include a supporting statement if, among other things, the Proposal is not submitted to the Company at least ninety (90) days before the anniversary date of the Notice of Meeting that was sent to the shareholders in connection with the previous annual meeting of shareholders of the Company. The deadline for submitting a proposal to the Company in connection with the next annual meeting of shareholders is February 3, 2022.

The foregoing represents a summary of certain applicable CBCA provisions and is qualified in its entirety by the full text of the CBCA. Shareholders should carefully review the provisions of the CBCArelating to any Proposals and consult with their own legal advisor with regards to such Proposals.

9 Interest of Informed Persons and Others in Material Transactions

Restructuring Transactions

In April and June 2019, we entered into a series of arrangements to restructure our outstanding indebtedness, reduce our interest and certain other payment obligations, and raise sufficient cash to build a robust balance-sheet for the next phase or our development (the "Restructuring Transaction").

On April 23, 2019, we completed transactions pursuant to a debt restructuring agreement we entered into on April 15, 2019 with SALP and certain of our subsidiaries (the "Restructuring Agreement"). Upon execution of the Restructuring Agreement, (i) SALP acquired 15,050,312 of our Common Shares (the "New Common Shares") at a price per Common Share of $15.21 (the "Transaction Price")¹, for a total purchase price of $228.9 million, which was satisfied by the cancellation of outstanding indebtedness in such amount owed by us to SALP, and (ii) certain warrants to purchase our Common Shares held by SALP were amended, with new warrants being issued (the "New Warrants"), exercisable for 168,735 Common Shares at a price per-share exercise price equal to the Transaction Price.

In connection with the Restructuring Transactions, in the event that SALP owns less than a majority of our issued and outstanding Common Shares, SALP was granted the right to (i) nominate the number of our directors to our Board that represents the same percentage of the total number of directors to be elected as the percentage of our issued and outstanding Common Shares owed by SALP at the record date for the applicable meeting of our shareholders, and (ii) nominate two directors to our Board for so long as it owns at least 10% of our issued and outstanding Common Shares. Our directors Alek Krstajic and Eugene Siklos were nominated pursuant to this right.

Debt Conversion

The New Common Shares have been issued to SALP in connection with the Restructuring Agreement. Under the Restructuring Agreement, all but $10 million of the outstanding debt we owed to SALP in the aggregate amount of $238,887,948 was converted into Common Shares. We also entered into a consolidated loan agreement with SALP on April 23, 2019, relating to future indebtedness secured against our assets (the "Consolidated Loan Agreement").

Warrant Amendments

The New Warrants have been issued to SALP in connection with the Restructuring Agreement. Prior to the closing of the transactions described above, SALP owned the following Warrants:

o 100,000 warrants, each of which entitled SALP to acquire one Common Share upon the payment of an exercise price equal to $520 per Warrant ("Warrants 1");

o 20,277 Warrants, each of which entitled SALP to acquire one Common Share upon the payment of an exercise price equal to an aggregate of $15,653,138 or the satisfaction of the loan made by SALP to us on September 10, 2013 in the principal amount of $10 million (plus interest accrued thereon) ("Warrants 2");

o 128,057 Warrants, each of which entitled SALP to acquire one Common Share upon the payment of an exercise price equal to $1,000 per Warrant ("Warrants 8"); and

¹  Such number of Common Shares and subscription price are presented following the Consolidation.

o 19,402 Warrants, each of which entitled SALP to acquire one series A preferred share of ours, or a Series A Preferred Share, upon the payment of an exercise price equal to $156.36 per Warrant ("Warrants 9").

Pursuant to the Restructuring Agreement, (i) the exercise price of Warrants 1, 2, 8 and 9 was amended to be the Transaction Price, and (ii) the terms of Warrant 9 were amended so that each Warrant 9 becomes exercisable for a Common Share instead of a Series A Preferred Share. The New Warrants may be exercised in whole or in part at SALP's option until April 23, 2027, at the Transaction Price per New Warrant.

Loan Agreement

Under the Consolidated Loan Agreement, all indebtedness we owed to SALP was reduced to a principal amount of $10 million of secured indebtedness to be used by us for the purpose of providing short-term working capital, paying transaction expenses, general corporate purposes and certain specified permitted debt payments.

On November 11, 2019, we entered into an amendment to our Consolidated Loan Agreement with SALP to provide us with a non-revolving $75.0 million secured line of credit, or the LOC. The Consolidated Loan Agreement between SALP and us dated as of April 23, 2019 has been amended to incorporate the terms of the LOC. As a result of the sale of Prometic Bioseparations Ltd, in November 2019 the LOC was reduced to $29.1 million. In September 2020, we drew down the available balance of $29.1 million under the LOC. The principal amount of $29.1 million borrowed under the LOC bears a stated interest of 10%, payable quarterly, and matures on April 23, 2024.

Registration Rights Agreement

Consonance Capital Management LP ("Consonance")

On April 23, 2019, we entered into a registration rights agreement with Consonance in connection with a private placement (the "Private Placement") of 4,931,161 Common Shares at a subscription price of $15.21 per Common Share for gross proceeds of $75 million². Pursuant to the registration rights agreement, we agreed to use our commercially reasonable efforts to have a registration statement registering the Common Shares purchased by Consonance in the Private Placement declared effective. We also agreed, among other things, to cause such registration statement to remain effective and to assist Consonance with offerings of such securities. On March 17, 2020, we amended the registration rights agreement to provide that we will use reasonable best efforts to have a registration statement declared effective by the SEC. We filed with the SEC a registration statement on Form F-1 to register the Common Shares held by Consonance Capital Master Account LP and P Consonance Opportunities Ltd., which was declared effective by the SEC on September 30, 2020. We also filed with the SEC a post-effective amendment no. 1 on Form F-3 to registration statement on Form F-1, which was effective on December 7, 2020.

We have also agreed, among other things, to indemnify each of Consonance from certain liabilities and to bear all fees and expenses incident to the registration of our Common Shares purchased by Consonance in the Private Placement, including fees, charges and disbursements of counsel to Consonance.

On October 29, 2020, we, SALP and Armistice entered into a securities purchase agreement, as amended in November 2020, and a registration right agreement. We

²  Such number of Common Shares and subscription price are presented following the Consolidation.

Liminal BioSciences
2021 Management Information Circular	Page | 41

agreed to file a resale registration statement with the SEC within 30 days of the closing of the offering for purposes of registering the resale of the Common Shares issuable in connection with the offering and the Common Shares underlying the warrants and pre-funded warrants issuable in the offering. We filed with the SEC a registration statement on Form F-3 to register the Common Shares held by SALP and Armistice, which was declared effective by the SEC on December 9, 2020.

Share Purchase Agreement with Fairhaven Pharmaceuticals Inc. ("Fairhaven")

In July 2020, we acquired all of the issued and outstanding shares in the capital of Fairhaven, a company with a preclinical research program of small molecule antagonists, and completed a concurrent private placement with each of Genesys, AmorChem LP and AmorChem II of $2.4 million aggregate principal amount of secured convertible debentures.

Under the terms of the acquisition, we will satisfy the aggregate purchase price of up to $8 million by the issuance of our Common Shares al to the shareholders of Fairhaven, being Genesys, AmorChem LP, MSBi Valorisation Inc. and The Royal Institution for the Advancement of Learning/McGill University subject to the achievement of certain pre-determined milestones. Investigational therapies developed in this program target a key chemoattractant and activator of eosinophils, which play a key role in Type 2 inflammation-driven diseases through tissue repair and resolution of inflammation, or the Fairhaven R&D Program.

In July 2020, we issued an aggregate of 202,308 of our Common Shares, representing $3.6 million of the aggregate purchase price, to the sellers, at a price per share equal to the five-trading day VWAP of our Common Shares on the Toronto Stock Exchange (the "TSX"). The remainder of the aggregate purchase price payable by us to the sellers is issuable upon, and subject to, the achievement of certain pre-determined research and development milestones prior to the fifth anniversary of the closing date of the acquisition, including $1.3 million upon the selection by us of a compound for development and $3.1 million upon the first dosing of a human in a Phase 1 clinical trial with a compound subject to the acquisition agreement. Any future shares to be issued as part of the milestone payments will be issued at a price per share equal to the five-trading day VWAP of our common shares prior to the achievement fof such milestone events.

The acquisition constitutes a "related party transaction" within the meaning of Regulation 61-101 – Protection of Minority Security Holders in Special Transactions ("Regulation 61-101"). We relied on the exemptions from the valuation and minority shareholder approval requirements contained in sections 5.5(a) and 5.7(1)(a) of Regulation 61-101 in respect of related party participation in the acquisition, as neither the fair market value of the shares distributed to, nor the consideration paid by, related parties, exceeded 25% of our market capitalization.

Each of Mr. Kenneth Galbraith and Mr. Gary Bridger, served on the board of directors of both the Company and Fairhaven prior to the closing of the acquisition. In addition, Mr. Kenneth Galbraith and Mr. Gary Bridger are officers of, and owned all of the shares in the capital of, Five Corners Capital Inc. ("FCC"), a former shareholder of Fairhaven immediately prior to the closing of the acquisition. Pursuant to a corporate reorganization of Fairhaven which occurred prior to the closing of the acquisition, Fairhaven repurchased all of the shares held by FCC in the capital of Fairhaven, such that FCC was no longer a shareholder of Fairhaven on the date of closing of the acquisition. Our independent directors reviewed and unanimously approved the acquisition.

Share Purchase Agreement with SALP and Armistice

On October 29, 2020, we, SALP and Armistice entered into a securities purchase agreement (the "Purchase Agreement"), as amended in November 2020, and a registration rights agreement, as part of a private placement. Pursuant to the Purchase Agreement, the selling shareholders purchased in a private placement an aggregate of (i) 5,757,894 Common Shares, (ii) prefunded warrants to purchase up to 557,894 Common Shares at an exercise price of US$0.001 per share and (iii) warrants

Schedule "B"
Summary of the Omnibus Incentive Plan

The Company has put in place an omnibus incentive plan which is administered by the Board (the "Omnibus Incentive Plan") on May 7, 2019, which said Omnibus Incentive Plan was approved by the Shareholders on June 19, 2019, in replacement of the Company's stock option plan and restricted share unit plan (collectively with the stock option plan, the "Prior Plans", the terms of which are summarized in Schedule "C" and Schedule "D" to this Management Information Circular) in respect of future awards, and no new awards will be granted under such Prior Plans. Outstanding awards granted pursuant to the Prior Plans will continue to be governed by the terms of such Prior Plans until such awards are exercised, expire, or are otherwise terminated or cancelled.

The Omnibus Incentive Plan is a long-term incentive plan that permits the grant of stock options, restricted share units ("RSUs") and performance share units ("PSUs," and together with the stock options and the RSUs, "awards") to directors, executive officers, employees and consultants of the Company and its subsidiaries (collectively, the "Eligible Participants"). The purpose of the Omnibus Incentive Plan is to grant awards to Eligible Participants, subject to certain conditions, in order to (a) provide a means through which the Company or a subsidiary may attract, retain and motivate qualified and able persons to advance its strategy; (b) provide an incentive to such Eligible Participants to continue their services for the Company or a subsidiary and to encourage such Eligible Participants whose skills, performance and loyalty to the objectives and interests of the Company or a subsidiary are necessary or essential to its success, image, reputation or activities; and (c) reward Eligible Participants for their performance of services while working for the Company or a subsidiary. All awards granted under the Omnibus Incentive Plan are subject to the clawback provision.

Limitation

i. The total number of Common Shares reserved for issuance, in the aggregate, under the Omnibus Incentive Plan is 3,749,714³, except that Common Shares will not be deemed to have been issued pursuant to the Omnibus Incentive Plan with respect to any portion of an award that is settled in cash;

ii. No award that can be settled in Common Shares issued from treasury may be granted if such grant would have the effect of causing the total number of Common Shares underlying awards made under the Omnibus Incentive Plan to exceed the number of Common Shares reserved for issuance; and

iii. The aggregate number of Common Shares issuable to insiders, within the meaning of Part 1 of the TSX Company Manual ("Insiders"), at any time under the Omnibus Incentive Plan and any other proposed or established share compensation arrangements, shall not exceed 10% of the issued and outstanding Common Shares, and the aggregate number of Common Shares issued to Insiders and their associates under the Omnibus Incentive Plan and any other proposed or established share compensation arrangements within any one-year period shall not exceed 10% of the issued and outstanding Common Shares.

Stock Options

The Board of the Company has the authority under the Omnibus Option Plan to establish the option price at the time each option is granted, which shall not be less than the market price of the Common Shares on the date of the grant. For purposes of the Omnibus Incentive Plan, the market price of the Common Shares as at a given date shall be the volume weighted average trading price on the TSX for the five trading days before such date.

³  Such number of Common Shares was determined following the one thousand for one consolidation of the Common Shares of the Company completed on July 5, 2019 (the "Consolidation"). The corresponding figure before the Consolidation became effective was 3,749,714,100 Common Shares.

Liminal BioSciences
2021 Management Information Circular	Page | 47

Subject to any vesting conditions set forth in a participant's grant agreement, an option shall be exercisable during a period established by the Board which shall not be more than ten years from the grant of the option. Should the expiration of the term of an option or the exercise period fall within a period during which the option holder cannot trade the Common Shares pursuant to the Company's policies (including the Company's insider trading policy) which are in effect at that time, the Omnibus Incentive Plan provides that such expiration date or exercise period shall be automatically extended without any further act or formality to that date which is the tenth (10^th) business day after the end of the blackout period, such tenth (10^th) business day to be considered the expiration of the term of such option for all purposes under the Omnibus Incentive Plan, and said "ten business day period" may not be extended by the Board.

RSUs and PSUs

Under the Omnibus Incentive Plan, the Board has the authority to grant RSUs and PSUs and to determine the terms and conditions of such grants, including the quantity, type of award, grant date, vesting conditions, vesting periods, settlement date and other terms and conditions with respect to these awards, all of which will be set out in the participant's grant agreement.

RSUs generally become vested, if at all, following a period of continuous employment, while the vesting of PSUs is generally, in whole or in part, conditioned on the attainment of specified performance metrics as may be determined by the Board.

The participant is entitled to receive, with respect to such portion of the RSUs or PSUs which has vested, (i) Common Shares (issued from treasury or purchased on the open market), (ii) cash based on the value of Common Shares or (iii) a combination thereof, as the case may be, all pursuant and subject to such restrictions and conditions as the Board may determine at the time of grant. The payout of an RSU or PSU will generally occur on the settlement date.

Dividend Equivalents

If, as the case may be, dividends (other than share dividends) are paid on the Common Shares, additional share unit equivalents will be automatically granted to each participant who holds RSUs or PSUs on the record date for such dividends, and be subject to the same vesting or other conditions applicable to the related RSUs or PSUs, as applicable.

Tax

Under the Omnibus Incentive Plan, each participant shall be responsible for paying all taxes, social security contributions (including, if the terms of the participant's option agreement so provide, and if lawful, employer social security contributions) and other liabilities arising out of or in connection with any awards or the acquisition, holding or disposal of Common Shares.

Effect of Termination

The provisions of the Omnibus Incentive Plan provide that:

i. upon a participant's ceasing to be an Eligible Participant as a result of his or her termination for cause (which includes gross misconduct, theft, fraud, breach of confidentiality or breach of the Company's code of business conduct and ethics and any other reason determined by the Company to be cause for termination in accordance with applicable law), any awards granted to such participant, whether vested or unvested on the termination date, shall terminate automatically and become void immediately on the termination date;

ii. upon a participant ceasing to be an Eligible Participant as a result of his or her resignation from the Company or a subsidiary, as applicable, or in the case of his or her termination without cause, (i) a portion of the PSUs and/or RSUs granted to such participant under the Omnibus Incentive Plan will immediately vest and be settled (based on the vesting terms up to the termination date, as determined in the final and sole discretion of the Board), (ii) all unvested options will be forfeited on the termination date, and (iii) vested options will remain exercisable until the earlier of (A) thirty (30) days after the termination date or the expiry date of the

	Liminal BioSciences Inc.
Page | 48	2021 Management Information Circular

options, after which time all options will expire, in the case of the individual's resignation or (B) ninety (90) days after the termination date or the expiry date of the options, after which time all options will expire, in the case of termination without cause; and

iii. upon a participant's termination of employment as a result of death or disability, (i) all rights, title and interest in options granted to such participant under the Omnibus Incentive Plan, which are unvested on the termination date, will continue to vest in accordance with the terms of this Omnibus Incentive Plan and the participant's grant agreement for a period of up to two years, subject to the underlying options' expiry date, (ii) vested options (including such options that vest during the period following the termination date) will remain exercisable until the earlier of (A) two years after the termination date and (B) the expiry date of the options, after which time all options will automatically expire, and (iii) a portion of PSUs and/or RSUs granted to the participant under the Omnibus Incentive Plan will immediately vest on the termination date and be settled.

Change of Control

A participant's grant agreement or any other written agreement between a participant and the Company may provide, where applicable, that unvested awards be subject to acceleration of vesting and exercisability in certain circumstances, including in the event of a Change of Control. The Board may at its discretion accelerate the vesting, where applicable, of any outstanding awards notwithstanding the previously established vesting schedule, regardless of any adverse or potentially adverse tax consequences resulting from such acceleration or, subject to applicable regulatory provisions and shareholder approval, extend the expiration date of any award, provided that the period during which an option is exercisable does not exceed ten years from the date such option is granted or that the period relating to RSUs and PSUs does not exceed three years. Similarly, in the event of a Change of Control, the Board will have the power, in its sole discretion, to modify the terms of the Omnibus Incentive Plan and/or the awards granted thereunder (including to cause the vesting of all unvested awards) to assist the participants to tender into a take-over bid or any other transaction leading to a Change of Control. In such circumstances, the Board shall be entitled to, in its sole discretion, provide that any or all awards shall terminate, provided that any such outstanding awards that have vested shall remain exercisable until consummation of such Change of Control, and/or permit participants to conditionally exercise awards, such conditional exercise to be conditional upon the take-up by such offeror of the Shares or other securities tendered to such take-over bid in accordance with the terms of such take-over bid (or the effectiveness of such other transaction leading to a Change of Control).

For purposes of the Omnibus Incentive Plan, unless otherwise defined in the employment agreement, if any, between a participant and the Company or a subsidiary, and unless otherwise defined in the participant's grant agreement or otherwise determined by the Board, "Change of Control" means the happening, in a single transaction or in a series of related transactions, of any of the following events:

i. any acquisition by a person (other than a non-arm's length party), or a combination of persons acting jointly or in concert of the direct or indirect beneficial ownership of securities of the Company representing 50% or more of the aggregate voting power of all of the Company's then issued and outstanding securities entitled to vote in the election of directors of the Company, other than any such acquisition that occurs upon the exercise or settlement of options or other securities granted by the Company under any of the Company's equity incentive plans;

ii. the sale or disposition of all or substantially all of the Company's assets, or consummation of any transaction, or series of related transactions, having similar effect;

iii. other than as a result of a solicitation by management of the Company, a change in the composition of the Board, which occurs at a single meeting of the shareholders or upon the execution of a shareholders' resolution, such that individuals who are members of the Board immediately prior to such meeting or resolution cease to constitute a majority of the Board;

iv. the dissolution, liquidation or winding up of the Company; or

v. an arrangement, amalgamation, merger, consolidation or similar transaction involving (directly or indirectly) the Company and, immediately after the consummation of such arrangement,

Liminal BioSciences
2021 Management Information Circular	Page | 49

amalgamation, merger, consolidation or similar transaction, the shareholders of the Company immediately prior thereto do not beneficially own, directly or indirectly, either (A) outstanding voting securities representing more than 50% of the combined outstanding voting power of the surviving or resulting entity in such amalgamation, merger, consolidation or similar transaction or (B) more than 50% of the combined outstanding voting power of the parent of the surviving or resulting entity in such arrangement, amalgamation merger, consolidation or similar transaction, in each case in substantially the same proportions as their beneficial ownership of the outstanding voting securities of the Company immediately prior to such transaction.

Non-Assignability of Awards

Each award granted under the Omnibus Incentive Plan is personal to the participant and shall not be assignable or transferable by the participant, whether voluntarily or by operation of law, except by will or by the laws of succession of the domicile of the deceased participant.

No award granted shall be pledged, hypothecated, charged, transferred, assigned or otherwise encumbered or disposed of on pain of nullity.

Amendments, Suspension and Discontinuation of the Omnibus Incentive Plan

The Board is entitled to suspend or terminate the Omnibus Incentive Plan at any time, or from time to time amend or revise the terms of the Omnibus Incentive Plan or of any granted award, provided that no such suspension, termination, amendment or revision will be made, (i) except in compliance with applicable law and with the prior approval, if required, of the shareholders, the TSX or any other regulatory body having authority over the Company, and (ii) if it would adversely alter or impair the rights of any participant, without the consent of the participant except as permitted by the terms of the Omnibus Incentive Plan, provided however, subject to any applicable rules of the TSX, the Board may from time to time, in its absolute discretion and without the approval of shareholders, make, amongst others, the following amendments to the Omnibus Incentive Plan or any outstanding award:

For greater certainty, the Board shall be required to obtain shareholder approval to make the following amendments:

o any increase in the maximum number of Common Shares that may be issuable pursuant to the Omnibus Incentive Plan;

o any extension of the term of an award beyond its original expiry time to the extent such amendment benefits an insider;

o any increase in the maximum number of Common Shares that may be issuable to insiders pursuant to the insider participation limit;

o any amendment to the amendment provisions of the Omnibus Incentive Plan.

Adjustment to Common Shares Subject to Outstanding Awards  

In the event of any subdivision, consolidation, reclassification, reorganization or any other change affecting the Common Shares, or any merger or amalgamation with or into another corporation, or any distribution to all security holders of cash, evidences of indebtedness or other assets not in the ordinary course, or any transaction or change having a similar effect, the Board shall in its sole discretion, subject to the required approval of any stock exchange, determine the appropriate adjustments or substitutions to be made in such circumstances in order to maintain the economic rights of the participants in respect of awards under the Omnibus Incentive Plan, including, without limitation, adjustments to the exercise price, the number and kind of securities subject to unexercised awards granted prior to such change and/or permitting the immediate exercise of any outstanding awards that are not otherwise exercisable.

The Company currently does not provide any financial assistance to participants under the Omnibus Incentive Plan.

Schedule "C"
Summary of the Stock Option Plan

The Company has put in place a stock option plan (the "Option Plan") for the benefit of eligible directors, officers, employees and service providers of the Company and its subsidiaries, as designated from time to time by the board of directors of the Company (the "Beneficiaries"), so as to encourage them to promote the business and affairs of the Company to the best of their abilities. Under the Option Plan, the Beneficiaries are granted, by means of stock options, the right to purchase common shares of the Company ("Common Shares") for cash. The Option Plan provides that the Board may grant options to Beneficiaries on terms that the Board may determine within the limitations defined in the Option Plan, including terms with respect to the vesting of options granted.

The maximum number of shares reserved for issuance under the Option Plan is 40,634,585⁴, which represents approximately 5% of the total number of Common Shares issued and outstanding as of December 31, 2018.

On August 7, 2018, the board of directors of the Company (the "Board") modified the Option Plan to (i) mainly clarify the dispositions related to the beneficiaries' retirement, and (ii) delegate to Liminal's Chief Executive Officer the ability to determine the number of options to be granted and grant such options to new hires and employees holding a position below the vice-president level, subject to respecting Liminal's guidelines on the number of options to be granted for each such position. Shareholder approval is not required for such amendments given that the Board has the full power and authority to amend the Option Plan with respect to any limitation of conditions on participation in the Option Plan as well as any amendment to any terms upon which options may be granted.

Limitation

i. The total number of Common Shares to be optioned under the Option Plan to any one individual shall not exceed five percent (5%) of the total of the issued and outstanding Common Shares;

ii. The total number of Common Shares to be optioned shall not exceed the number of Common Shares reserved for issuance under the Option Plan;

iii. The total number of Common Shares i) issued to Insiders of Liminal within any one-year period, and ii) issuable to Insiders of Liminal, at any time, under the Option Plan or when combined with all other security based compensation arrangements of Liminal (collectively, the "Share-Based Plans"), cannot exceed ten percent (10%) of the issued and outstanding Common Shares; and

iv. The total number of Common Shares issued to any one Insider under the Share-Based Plans (less Common Shares already issued as compensation to Insiders) within a one-year period shall not exceed five percent (5%) of the Common Shares outstanding on the date of issuance of such Shares.

⁴  On a pre-Consolidation basis.

Granting Procedures

Under the Compensation Policy, options to purchase Common Shares are granted to all new employees, including executives, on commencement of employment. The number of options so granted will vary depending on the Beneficiary's position and responsibilities within the Company.

Subject to the number of Common Shares available for issuance under the Option Plan and to applicable regulations, stock options are granted annually to executives by the Board based upon recommendation by the HR & Corporate Governance Committee. The purpose of these annual grants is i) to motivate and retain executives, to sustain a commitment to long-term profitability and to maximize shareholder value and ii) to recognize and reward individual performance.

The Chief Executive Officer assists the HR & Corporate Governance Committee in determining the number of options granted to Beneficiaries. The number of options granted is determined based on the Beneficiary's position and responsibility level in the Company and the Chief Executive Officer's assessment of the overall performance of each Beneficiary for the previous financial year, without taking into account the number of options already held by such Beneficiary.

The number of options to be granted to the Chief Executive Officer is recommended by the HR & Corporate Governance Committee and approved by the Board.

The strike price, the vesting conditions and the terms of options are determined by the Board at the time of the grant each year, upon recommendation by the HR & Corporate Governance Committee.

Option Price

The Board of the Company has the authority under the Option Plan to establish the option price at the time each option is granted, which may not be less than the volume-weighted average trading price of the Common Shares on the TSX, or another stock exchange where the majority of the trading volume and value of the Common Shares occurs, for the last five (5) trading days immediately preceding the day on which the option is granted, which is outside of a blackout period. The volume-weighted average trading price of the Common Shares is calculated by dividing the total value by the total volume of Common Shares traded for the relevant period.

Vesting and Term

Under the Option Plan, the period during which an option is exercisable shall not, subject to the provisions of the Plan, exceed ten (10) years from the date the option is granted. In the absence of any other specifications made by the Board at the time of the grant, an option shall expire five (5) years following its date of grant.

Should the expiration of the term of an option or the exercise period fall within a period during which the option holder cannot trade the Common Shares pursuant to the Company's insider trading policy which is in effect at that time, the Option Plan provides that such expiration date or exercise period shall be automatically extended without any further act or formality to that date which is the tenth (10^th) business day after the end of the blackout period, such tenth (10^th) business day to be considered the expiration of the term of such option for all purposes under the Option Plan, and said "ten business day period" may not be extended by the Board.

November 2012 to May 2017

All options granted by the Company between November 12, 2012 and May 18, 2017 under the Option Plan have a five-year term. These options granted under the Option Plan may be exercised in whole or in part within the periods stipulated by the Board or, failing such stipulation, on a cumulative basis staggered over a five-year period at a rate of twenty-five percent (25%) per annum calculated from the date the options are granted.

Liminal BioSciences
2021 Management Information Circular	Page | 53

Since May 2017

All options granted by the Company after May 18, 2017 under the Option Plan have a ten-year term to better reflect the long-term developing cycle of our therapeutics and provide an ability for executives to focus on longer-term value creation.

Tax

Under the Option Plan, each optionee shall be responsible for paying all income and other taxes applicable to transactions involving the options, including, without limitation, any taxes payable on exercise of the options, the sale or other disposition of the Company's Shares, or other distributions paid on the Common Shares.

Effect of Termination

The provisions of the Option Plan provide that:

i. upon a Beneficiary's employment being terminated for cause or upon a Beneficiary ceasing to be a director or an officer by reason of his being removed or becoming disqualified for cause from being a director or officer by law, any vested and unvested option granted to him shall terminate forthwith;

ii. upon a Beneficiary's employment being terminated by the Company not for cause, any option vested at the time of such termination or cessation may be exercised by the Beneficiary. Such option shall be exercisable prior to the expiration of the term of the option;

iii. upon a Beneficiary's resignation of employment before being eligible for retirement, any option vested at the time of such resignation may be exercised by the Beneficiary within ninety (90) days after such resignation or prior to the expiration of the term of the option, whichever occurs earlier;

iv. if a Beneficiary resigns while being eligible for retirement (as defined in the Option Plan) (a) for grants under which options are fully vested at the retirement date, vested options are eligible for exercise by the Beneficiary and shall expire at the term determined at the grant date; (b) for grants under which options are partially vested at the retirement date, vested options are eligible for exercise by the Beneficiary.

Schedule "D"
Summary of the RSU Plan

The Company has put in place a restricted share unit plan (the "RSU Plan") to enhance the Company's ability to attract and retain talented individuals to serve as executive officers or in key management positions within the Company and of its Subsidiaries, to reward these participants and to promote an alignment of interests between such participants and the shareholders of the Company. The Restricted Share Units ("RSUs") granted under the RSU Plan may vest solely based on time or on the achievement of future performance conditions. The performance-based RSUs are tied to achievement of certain strategic objectives over a three-year period. The three-year period starts from the 1^st day of the financial year during which a grant is made to the last day of the second financial year following the financial year during which a grant has been made (a "Cycle"). In 2018, 75% of the RSUs granted under the RSU Plan were based on performance conditions and 25% were time-based.

The maximum number of shares reserved for issuance under the RSU Plan is 38,360,248, which represents approximately 5% of the total number of Common Shares issued and outstanding as of December 31, 2018.

On March 20, 2019, the board of directors of the Company (the "Board") modified the RSU Plan to mainly clarify the dispositions related to the Participants' retirement, Shareholder approval is not required for such amendment given that the Board has the full power and authority to amend the RSU Plan with respect to any limitation of conditions on participation in the Plan as well as any amendment to any terms upon which RSUs may be granted and exercised, including the vesting conditions. Other minor amendments were brought to the RSU Plan to clarify certain dispositions, which do not require shareholders' approval as per the provisions related to the amendments of the plan under the RSU Plan.

Eligible Participants

Under the RSU Plan, the "Participants" are the, Chief Executive Officer, the chief operating officer, the chief financial officer, the chief legal officer, the chief medical officer, any vice-presidents, employee directors or employee director-level executives and any other officers or management members of the Company, or of a Subsidiary, who have been granted RSUs as designated in writing by the HR & Corporate Governance committee, upon the recommendation of the Chief Executive Officer and subject to the Board's approval. Non-executive members of the Board are not eligible to be Participants for the purposes of the RSU Plan.

The Board shall have, at all times, the power to cancel, annul, rescind or otherwise remove a participant's designation or position as qualifying as a Participant under the RSU Plan. For greater certainty, such action by the Board shall not affect any RSUs already credited to such individual's account.

Limitation

The maximum percentage of Common Shares issuable to Insiders (as such term is defined in the RSU Plan) under the RSU Plan and any other share compensation arrangements of the Company, at any time, is ten percent (10%) of the issued and outstanding Common Shares. The percentage of Common Shares issued to insiders of the Company within any one-year period, under all security-based compensation plans, cannot, in the aggregate, exceed ten percent (10%) of the issued and outstanding Common Shares of the Company.

Vesting and Term

Time-Based Vesting.Each RSU may vest and may be eligible for conversion and releaseat the rate of 33 1/3 % on each December 31^st within the Cycle. The Board may, in its discretion, permit the immediate vesting, and conversion, of all or any portion of an unvested RSU.

Conditions-Based Vesting: RSUs granted prior to May 10, 2017. At each regular Board meeting, the Board shall determine which vesting conditions of any previously granted RSUs were achieved. The relevant RSUs for which the vesting conditions were deemed to be achieved by the Board will become

Liminal BioSciences
2021 Management Information Circular	Page | 57

vested,in whole or in part, based on the level of achievement of said vesting conditions, and will be eligible for conversion and release.

Conditions-Based Vesting: RSUs granted on or after May 10, 2017. At the end of each Cycle, the Board shall determine which vesting conditions of RSUs granted were achieved. The relevant RSUs for which the vesting Conditions were deemed to be achieved by the Board will become vested,in the percentage determined by the Board based on the level of achievement of said vesting conditions, and will be eligible for conversion and release.

Regardless of the timing when RSUs were granted, the Board has until the 31^st day of March following the end of a Cycle, or 90 days following an Expiration Date (as defined in the RSU Plan), to determine which vesting conditions were achieved under the relevant Cycle or grant period (if the RSUs were granted outside of a Cycle). RSUs in respect of which the vesting conditions are not deemed to be met by these deadlines shall be automatically cancelled, unless determined otherwise by the Board.

Conversion and Release

The Participant is entitled to receive, with respect to such portion of the RSU which has vested, an amount equal to one Common Share for each RSU (the "Payout Amount"). The Payout Amount shall be satisfied by the issuance from treasury of a number of Common Shares equal to the Payout Amount, subject to any required regulatory authorities' approval. Said Common Shares may be sold on the open market at the Participant's discretion.

Tax

Each Participant shall be responsible for paying all income and other taxes applicable to transactions involving the RSUs held by the Administrative agent (as defined in the RSU Plan) on his or her behalf, including, without limitation, any taxes payable on conversion and release of the RSUs, the sale or other disposition of the Common Shares, and dividends (whether cash or otherwise) or other distribution paid on the Common Shares.

All unvested RSUs shall be cancelled as at the date of termination;

ii. in the case of a Participant's Termination because of Retirement (as defined in the RSU Plan):

(a) after the end of the second year of a Cycle or before the Expiration Date, the RSUs will continue to remain in force until the end of the Cycle, or until the Expiration Date, and will be eligible for vesting and ultimately for conversion and release for a period of 90 days following the end of such Cycle or such Expiration Date, provided that the Vesting Conditions have been met at the end of such Cycle or at such Expiration Date;

(b) after the end of the first year of a Cycle but before the end of the second year of a Cycle, (i)vesting of RSUs subject to time-based vesting will stop one full year after the Participant's last day of employment, and (ii) two-thirds (2/3rds) of RSUs subject to performance-based vesting will remain in force until the end of the Cycle, or until the Expiration Date, and will be eligible for vesting and ultimately for conversion and release for a period of 90 days following the end of such Cycle or such Expiration Date, provided that the Vesting Conditions have been met at the end of such Cycle or at such Expiration Date;

iv. in the case of a Participant's Termination for just cause or a Participant resigning from his position, all RSUs shall be cancelled immediately as of the date on which the Participant is advised of the Termination, or as of the Participant's effective resignation date, without taking into account any applicable notice period or severance payments made in lieu of such notice.

Successors and Assigns

The RSU Plan shall be binding on all successors and assigns of the Company and a Participant, including without limitation, the estate of such Participant and the executor, liquidator, administrator or trustee of such estate, or any receiver or trustee in bankruptcy or representative of the Participant's creditors.

The Meeting is held for the following purposes:

3 to appoint the auditors for the ensuing year and to authorize the directors to fix their remuneration (for details, see subsection "Appointment of Auditors" under the "Business of the Meeting" section of the Management Information Circular);

4 to consider, and if deemed advisable, pass a special resolution (the "Special Resolution"), the full text of which is reproduced in Schedule "E" to the Management Information Circular, amending the articles of incorporation of the Company changing the place in Canada where the registered office is situated, from the province of Québec to Ontario, effective as at the discretion of the Board (for details, see subsection "Amendment to Articles of Incorporation" under the "Business of the Meeting" section of the Management Information Circular); and

5 to transact such other business as may properly be brought before the Meeting or any reconvened meeting following its adjournment or postponement.

Shareholders are reminded to review the Management Information Circular carefully before voting because it has been prepared to help you make an informed decision.

1.1 Notice-and-Access

This year, as permitted by Canadian securities regulators, you are receiving this notification as the Company has decided to use the "notice-and-access" mechanism for delivery to the shareholders of this notice of annual and special meeting of shareholders, the Management Information Circular and other proxy-related materials (the "Meeting Materials") as well as the annual audited consolidated financial statements of the Company for the financial year ending December 31, 2020, together with the independent auditor's report thereon and related management's discussion and analysis (together, the "Financial Statements"). Notice-and-access is a set of rules that allows issuers to post electronic versions of proxy-related materials online, via SEDAR and one other website, rather than mailing paper copies of such materials to shareholders. Under notice-and-access, shareholders still receive a proxy form or voting instruction form enabling them to vote at the Company's Meeting. However, instead of a paper copy of the Meeting Materials and the Financial Statements, shareholders receive a notice which contains information on how they may access the Meeting Materials and the Financial Statements online and how to request a paper copy. The use of notice-and-access will directly benefit the Company by substantially reducing its printing and mailing costs, is more environmentally friendly as it reduces paper use and provides more timely access to materials by shareholders.
