AGREEMENT

 

NOW, THEREFORE,
in consideration of the foregoing premises and the mutual covenants and agreements contained herein, and for other good and valuable
consideration, the receipt and sufficiency of which are hereby acknowledged, the Parties, intending to be legally bound hereby,
agree as follows:

 

Section 1. Board Composition and Related
Agreements.

 

(a) Board Appointment.

 

(i)    
Following the execution of this Agreement and prior to the Closing Date, but conditional and effective upon the Closing
Date, the Board and all applicable committees thereof shall take all necessary actions to appoint Paul B. Manning (the “New
Director”) as a director of the Company. Mr. Manning shall serve as Class III director for a term expiring at the Company’s
2021 annual meeting of stockholders, and until his successor is elected and qualified, or until such director’s earlier resignation,
removal or death. Following the execution of this Agreement and prior to the Closing Date, one of the current members of the Board
will resign, conditional and effective upon the Closing Date, and Mr. Manning will fill the vacancy created by such resignation.
The size of the Board shall not exceed nine (9) directors during the Cooperation Period (as defined below) unless at least two-thirds
of the members of the Board approve an increase in the size of the Board.

 

(ii)     The
Parties acknowledge that, at all times while serving as a member of the Board (and as a condition to such service), the New
Director shall be subject to all policies, codes, guidelines and reasonable requests applicable to Board members generally,
each as may be amended from time to time, including the Company’s Code of Conduct, and shall have the same rights and
benefits, including with respect to insurance, indemnification, compensation, fees and reimbursement of expenses, as are
applicable to all non-employee directors of the Company.

 

     

     

    

 

(iii)    
Subject to any applicable corporate governance documents of the Company and applicable stock exchange rules, concurrently
with the New Director’s appointment to the Board, Mr. Manning shall be appointed to the Nominating and Corporate Governance
Committee of the Board and, the Company agrees to maintain such committee appointment during the term of this Agreement, as long
as such New Director (or, as applicable, their Replacement Designee (as defined below)) continues to serve on the Board.

 

(iv)    
During the Cooperation Period, as long as the New Company Investor owns at least 66% of the Company’s Voting Securities
owned by the New Company Investor as of the Closing Date (and subject to adjustment for stock splits, reclassifications, combinations,
buybacks or similar transactions) and in the event that the New Director (or any Replacement Designee (as defined below), as applicable)
becomes unwilling or unable to serve as a director and ceases to be a director, resigns as a director or is removed as a director,
or for any other reason fails to serve or is not serving as a director at any time prior to the end of the Cooperation Period,
then the members of the New Company Investor shall be entitled to designate, subject to the approval (not to be unreasonably withheld)
of the applicable committee of the Board, a candidate for replacement of such New Director (such replacement, a “Replacement
Designee”). Any Replacement Designee shall qualify as an independent director of the Company under applicable rules of
the SEC, the rules of any stock exchange on which the Company is traded and applicable governance policies of the Company. Following
the approval of a candidate for Replacement Designee by the applicable committee of the Board, the Board shall promptly appoint
such Replacement Designee to the Board. Upon his or her appointment to the Board, such Replacement Designee shall be deemed a New
Director for all purposes under this Agreement.

 

(v)    
So long as the New Director (or any Replacement Designee) serves on the Board
in accordance with the terms of this Agreement, within a reasonable time prior to the filing
with the SEC of the Company’s proxy statement or information statement with
respect to each annual or special meeting of the stockholders of the Company (each, a “Stockholder Meeting”),
the Company shall provide the New Company Investor with the reasonable opportunity
to review the filing and comment on the information contained in such proxy or information statement applicable to the New Company
Investor and the Company shall take into consideration all reasonable comments from the New Company Investor.

 

(b) Additional Agreements.

 

(i)    
The New Company Investor agrees (A) to cause its Affiliates and Representatives (each as defined below) to comply with the
terms of this Agreement and (B) that it shall be responsible for any breach of this Agreement by any such Affiliate or Representative.
A breach of this Agreement by an Affiliate or Representative of the New Company Investor, if such Affiliate or Representative is
not a Party hereto, shall be deemed to occur if such Affiliate or Representative engages in conduct that would constitute a breach
of this Agreement if such Affiliate or Representative were a Party hereto to the same extent as the New Company Investor.

 

(ii)    
During the Cooperation Period, each New Company Investor agrees that it shall, and shall cause each of its Affiliates to,
appear in person or by proxy at each Stockholder Meeting and vote all Voting Securities beneficially owned, directly or indirectly,
by the New Company Investor or such Affiliate (or which the New Company Investor or such Affiliate has the right or ability to
vote as of the applicable record date) at such meeting (A) in favor of the slate of directors recommended by the Board, (B) against
the election of any nominee for director not approved, recommended and nominated by the Board for election at any such Stockholder
Meeting and (C) in accordance with the Board’s recommendation with respect to any other matter presented at such Stockholder
Meeting; provided, that each New Company Investor shall be permitted to vote in its sole discretion with respect to
any proposals relating to (i) an Extraordinary Transaction (as defined below) with a third party that is not an Affiliate of the
New Company Investor, or (ii) amendments to the Company’s Certificate of Incorporation, Bylaws, or other governing documents
of the Company that materially diminish stockholder rights.

(iii)    
 During the Cooperation Period, upon reasonable written request from the Company, the New Company Investor will promptly
provide the Company with information regarding the amount of Voting Securities then beneficially owned by the New Company Investor.
Such information provided to the Company will be kept strictly confidential unless required to be disclosed pursuant to law, legal
process, subpoena, the rules of any stock exchange or any legal requirement or as part of a response to a request for information
from any governmental authority with jurisdiction over the Company.

 

(iv)    
Each Party (as defined below) agrees that, during the Cooperation Period, it shall not institute, solicit, join or assist
in any litigation, arbitration or other proceeding (each, a “Legal Proceeding”) against or involving the other
Party, any Affiliate of the other Party or any of their respective current or former directors or officers (including derivative
actions), other than (A) to enforce the provisions of this Agreement, (B) to make counterclaims with respect to any proceeding
initiated by, or on behalf of one Party or its Affiliates against the other Party or its Affiliates, (C) to bring bona fide commercial
disputes that do not relate to the subject matter of this Agreement, (D) in connection with the Merger Agreement or any Ancillary
Agreement (as defined in the Merger Agreement); or (E) to exercise statutory appraisal rights; provided, that the foregoing
shall not prevent any Party or any of its Representatives from responding to oral questions, interrogatories, requests for information
or documents, subpoenas, civil investigative demands or similar processes (each, a “Legal Requirement”) in connection
with any Legal Proceeding if such Legal Proceeding has not been initiated by, on behalf of or at the suggestion of such Party; provided, further,
that in the event that any Party or any of its Representatives receives such Legal Requirement, such Party shall give prompt written
notice of such Legal Requirement to the other Party (except where such notice would be legally prohibited or not practicable).
Each Party represents and warrants that neither it nor any assignee has filed any lawsuit against the other Party.

Committee in connection with the Company’s 2021 Annual Meeting of Stockholders, the Company’s 2022 Annual Meeting of

which the Board may accept or reject in its sole and absolute discretion, so long as any such request is not publicly disclosed

email and reasonably in advance when such “open window” director trading periods begin and end. The Company acknowledges

court within the State of Delaware) (the “Chosen Courts”). Each Party hereby irrevocably submits with regard

or its property is exempt or immune from jurisdiction of any Chosen Court or from any legal process commenced in the Chosen Courts
(whether through service of notice, attachment prior to judgment, attachment in aid of execution of judgment, execution of judgment
or otherwise) and (c) to the fullest extent permitted by applicable legal requirements, any claim that (i) the suit, action or
proceeding in any Chosen Court is brought in an inconvenient forum, (ii) the venue of such suit, action or proceeding is improper
or (iii) this Agreement, or the subject matter hereof, may not be enforced in or by the Chosen Courts. EACH PARTY HERETO HEREBY
IRREVOCABLY WAIVES ANY AND ALL RIGHT TO TRIAL BY JURY IN ANY LEGAL PROCEEDING ARISING OUT OF OR RELATED TO THIS AGREEMENT.

Section 14. Non-Disparagement.

 

(a) Subject
to applicable law, each of the Parties covenants and agrees that during the period commencing upon the execution of this Agreement
and ending on the earlier of (i) the conclusion of the Cooperation Period and (ii) such time as the other Party or any of its Affiliates,
Representatives, successors or assigns shall have breached this Section 14(a), neither it nor any of its respective
Affiliates or any Representatives acting on their behalf, or its successors or assigns, shall in any way disparage, slander, attempt
to discredit, call into disrepute, defame, make or cause to be made any statement or announcement that constitutes an ad

(including any current or former officer of a Party or a Party’s subsidiaries), directors (including any current or former
director of a Party or a Party’s subsidiaries) or Representatives.

 

(b) Nothing

complying with its respective disclosure obligations under law, legal process, subpoena, the rules of any stock exchange or any
legal requirement or as part of a response to a request for information from any governmental authority with jurisdiction over
the Party from whom information is sought.

 

Section 15. Termination.
The obligations of the Parties under this Agreement will terminate on the date that is the end date of the Cooperation Period,
unless another period is specifically set forth herein or otherwise mutually agreed in writing by each Party. The obligations of
the New Company Investor pursuant to Sections 1 and 2 shall terminate in the event that the Company materially breaches
its obligations to the New Company Investor pursuant to Section 1 or the representations and warranties in Section 3
of this Agreement (as they pertain to the Company) and such breach (if capable of being cured) has not been cured within thirty
(30) calendar days following written notice of such breach from the New Company Investor, or, if impossible to cure within 30 calendar
days, the Company has not taken substantive action to correct within thirty (30) calendar days following written notice of such
breach from the New Company Investor. Notwithstanding the foregoing, (a) Section 7 through Section 13,
this Section 15, and Section 16 through Section 20 of this Agreement
will survive the termination of this Agreement; and (b) no termination of this Agreement will relieve any Party of liability for
any breach of this Agreement arising prior to such termination.

 

Section 16. No Waiver.
Any waiver by any Party of a breach of any provision of this Agreement shall not operate as or be construed to be a waiver of any
other breach of such provision or of any breach of any other provision of this Agreement. The failure of a Party to insist upon
strict adherence to any term of this Agreement on one or more occasions shall not be considered a waiver of, or deprive that Party
of the right thereafter to insist upon strict adherence to, that term or any other term of this Agreement.

 

Section 17. Entire
Agreement; Amendments. This Agreement contains the entire understanding of the Parties with respect to the subject matter hereof.
This Agreement may only be amended pursuant to a written agreement executed by the Company, Liquidia and the New Company Investor.

 

Section 18. Successors
and Assigns. This Agreement may not be transferred or assigned by any Party without the prior written consent of the other
Party. Any purported assignment without such consent is null and void. Subject to the foregoing, this Agreement shall be binding

Party Beneficiaries. This Agreement is solely for the benefit of the Parties and is not enforceable by any other person.

Liquidia to Acquire RareGen, LLC, and
Expand Presence in PAH

 

		·	Acquisition Bolsters Liquidia’s Capabilities in Pulmonary Arterial Hypertension (PAH) and Commercial Readiness for
LIQ861, if Approved

 

		·	Two New Directors, - Roger Jeffs, Ph.D. and Paul Manning, to Join Board Concurrent with Acquisition Close

 

RESEARCH TRIANGLE PARK, N.C., June
29, 2020 - Liquidia Technologies, Inc. (NASDAQ: LQDA), a late-stage clinical biopharmaceutical company focused on
the development and commercialization of novel products using its proprietary PRINT® technology, announced
it has entered into a definitive agreement to acquire RareGen, LLC, a portfolio company of PBM Capital, through an all-stock merger.
Liquidia and RareGen will consolidate under a new holding company, to be named Liquidia Corporation, which is expected to trade
on the Nasdaq Capital Market under the ticker symbol “LQDA,” as the successor to Liquidia Technologies. RareGen provides
strategy, investment, and commercialization for rare disease pharmaceutical products. RareGen has a small, targeted sales force
focused on PAH.

 

RareGen acquired the right to promote
Sandoz’s first-to-file generic of Remodulin® (treprostinil) for the treatment of patients with PAH. In March 2019, Sandoz
and RareGen launched their generic treprostinil injection, making it the first generic of Remodulin® to market. Liquidia Corporation
will assume RareGen’s responsibilities under the agreement with Sandoz following closing of the merger transaction.

 

This acquisition reinforces Liquidia’s
commitment to the PAH community and continued pursuit to address the unmet needs of patients and the healthcare professionals who
treat them. The potential introduction of LIQ861 as a more convenient inhaled treprostinil over the currently available inhaled
option, combined with RareGen’s parenteral treprostinil options emphasize Liquidia’s commitment to addressing the patient
continuum of treatment. In addition, these combined entities further enhance the organization’s knowledge base, customer
reach and commercial planning in preparation for the potential launch of LIQ861, if approved.

 

“The acquisition of RareGen creates
tremendous value for Liquidia’s stockholders and, most importantly, patients,” stated Neal Fowler, Chief Executive
Officer of Liquidia. “RareGen offers a knowledgeable team and scalable sales force, coupled with rights to commercialize
an important PAH product that complements Liquidia’s lead product candidate in PAH, LIQ861. The acquisition of RareGen bolsters
Liquidia’s ability to advance much needed treatment options for the PAH community."

Following the closing of the merger
transaction, Liquidia and RareGen will be wholly owned operating subsidiaries of Liquidia Corporation. Under the terms of the merger
agreement, Liquidia will acquire 100 percent ownership of RareGen for 6,166,666 shares of Liquidia Corporation common stock. RareGen
members are entitled to receive between 1,458,333 and 2,708,333 shares of additional Liquidia Corporation common stock if certain
RareGen net sales thresholds are met in 2021. The transaction was approved by the boards of directors of Liquidia and RareGen and
is expected to close in the fourth quarter of 2020, subject to customary closing conditions, including approval by Liquidia Technologies
stockholders and a registration statement on Form S-4 being declared effective by the Securities and Exchange Commission (SEC). Under
the terms of the merger agreement, at the close of the transaction Liquidia Technologies stockholders will receive an identical
number of shares of Liquidia Corporation common stock in exchange for their Liquidia Technologies common stock.

 

At the closing of the merger transaction,
two of RareGen’s current directors, Paul B. Manning, of PBM Capital Group, a current investor in Liquidia and beneficial
owner of a majority of RareGen’s equity, and Roger A. Jeffs, Ph.D., former Co-CEO of United Therapeutics, will join the Liquidia
Corporation Board of Directors and one member of the current Liquidia Board of Directors will resign, resulting in a nine member
board of directors post-closing.

 

“The combined company formed
through this transaction aims to expand access and treatment options for PAH patients,” said Paul Manning, President
and CEO of PBM Capital Group. “We are excited about LIQ861 and think it will offer a more convenient, and portable treatment
option for inhaled Treprostinil. RareGen’s commitment to, and knowledge in the PAH space will amplify Liquidia’s efforts
to support this difficult-to-treat patient group.

 

Certain of Liquidia’s stockholders,
representing approximately 38.5 percent of its current outstanding common stock, have agreed to vote in favor of the merger agreement.

 

Jefferies LLC acted as exclusive financial advisor, and DLA
Piper LLP acted as legal counsel, to Liquidia in connection with the transaction.

Cautionary Statements Regarding
Forward-Looking Statements

This communication contains “forward-looking
statements” within the meaning of the federal securities laws, including Section 27A of the Securities Act of 1933,
as amended, and Section 21E of the Securities Exchange Act of 1934, as amended. In this context, forward-looking statements often
address expected future business and financial performance and financial condition, and often contain words such as “expect,”
“anticipate,” “intend,” “plan,” “believe,” “seek,” “see,”
“will,” “would,” “target,” similar expressions, and variations or negatives of these words.
Forward-looking statements by their nature address matters that are, to different degrees, uncertain, such as statements about
the potential timing or consummation of the proposed merger transaction or the anticipated benefits thereof, including, without
limitation, future financial and operating results. We caution readers that these and other forward-looking statements are not
guarantees of future results and are subject to risks, uncertainties and assumptions that could cause actual results to differ
materially from those expressed in any forward-looking statements. Important risk factors that may cause such a difference include,
but are not limited to risks and uncertainties related to (i) the ability to obtain Liquidia Technologies stockholder and regulatory
approvals, or the possibility that they may delay the merger transaction or that such regulatory approval may result in the imposition
of conditions that could cause the parties to abandon the merger transaction, (ii) the risk that a condition to closing of the
merger transaction may not be satisfied; (iii) the ability of Liquidia Technologies and RareGen to integrate their businesses
successfully and to achieve anticipated cost savings and other synergies, (iv) the possibility that other anticipated benefits
of the proposed merger transaction will not be realized, including without limitation, anticipated revenues, expenses, earnings
and other financial results, and growth and expansion of the new combined company’s operations, and the anticipated tax
treatment, (v) potential litigation relating to the proposed merger transaction that could be instituted against Liquidia, RareGen
or their respective officers or directors, (vi) possible disruptions from the proposed merger transaction that could harm Liquidia
Technologies’ or RareGen’s business, including current plans and operations, (vii) the ability of Liquidia Technologies
or RareGen to retain, attract and hire key personnel, (viii) potential adverse reactions or changes to relationships with employees,
customers, suppliers, licensees, collaborators, business partners or other parties resulting from the announcement or completion
of the merger transaction, (ix) potential business uncertainty, including changes to existing business relationships, during the
pendency of the merger transaction that could affect Liquidia’s and/or RareGen’s financial performance, (x) certain
restrictions during the pendency of the merger transaction that may impact Liquidia Technologies’ or RareGen’s ability
to pursue certain business opportunities or strategic transactions, (xi) continued availability of capital and financing and rating
agency actions, (xii) legislative, regulatory and economic developments and (xiii) unpredictability and severity of catastrophic
events, including, but not limited to, global pandemics such as coronavirus, acts of terrorism or outbreak of war or hostilities,
as well as management’s response to any of the aforementioned factors. These risks, as well as other risks associated with
the proposed merger transaction, will be more fully discussed in the proxy statement/prospectus that will be included in the registration
statement on Form S-4 that will be filed with the SEC in connection with the proposed merger transaction. While the list of factors
presented here is, and the list of factors to be presented in the registration statement on Form S-4 are, considered representative,
no such list should be considered to be a complete statement of all potential risks and uncertainties. Unlisted factors may present
significant additional obstacles to the realization of forward-looking statements. Consequences of material differences in results
as compared with those anticipated in the forward-looking statements could include, among other things, business disruption, operational
problems, financial loss, legal liability to third parties and similar risks, any of which could have a material adverse effect
on Liquidia Technologies’ or RareGen’s consolidated financial condition, results of operations, credit rating or liquidity.
Neither Liquidia Technologies nor RareGen assumes any obligation to provide revisions or updates to any forward-looking statements,
whether as a result of new information, future developments or otherwise, should circumstances change, except as otherwise required
by securities and other applicable laws.

AGREEMENT

 

NOW, THEREFORE,
in consideration of the foregoing premises and the mutual covenants and agreements contained herein, and for other good and valuable
consideration, the receipt and sufficiency of which are hereby acknowledged, the Parties, intending to be legally bound hereby,
agree as follows:

 

Section 1. Board Composition and Related
Agreements.

 

(a) Board Appointment.

 

(i)    
Following the execution of this Agreement and prior to the Closing Date, but conditional and effective upon the Closing
Date, the Board and all applicable committees thereof shall take all necessary actions to appoint Roger A. Jeffs, Ph.D. (the “New
Director”) as a director of the Company. Dr. Jeffs shall serve as Class I director for a term expiring at the Company’s
2022 annual meeting of stockholders, and until his successor is elected and qualified, or until such director’s earlier resignation,
removal or death. Following the execution of this Agreement and prior to the Closing Date, one of the current members of the Board
will resign, conditional and effective upon the Closing Date, and Dr. Jeffs will fill the vacancy created by such resignation.
The size of the Board shall not exceed nine (9) directors during the Cooperation Period (as defined below) unless at least two-thirds
of the members of the Board approve an increase in the size of the Board.

 

(ii)     The
Parties acknowledge that, at all times while serving as a member of the Board (and as a condition to such service), the New
Director shall be subject to all policies, codes, guidelines and reasonable requests applicable to Board members generally,
each as may be amended from time to time, including the Company’s Code of Conduct, and shall have the same rights and
benefits, including with respect to insurance, indemnification, compensation, fees and reimbursement of expenses, as are
applicable to all non-employee directors of the Company.

 

     

     

    

 

(iii)    
Subject to any applicable corporate governance documents of the Company and applicable stock exchange rules, concurrently
with the New Director’s appointment to the Board, Dr. Jeffs shall be appointed to the Compensation Committee of the Board
and, the Company agrees to maintain such committee appointment during the term of this Agreement, as long as such New Director
(or, as applicable, their Replacement Designee (as defined below)) continues to serve on the Board.

 

(iv)    
During the Cooperation Period, as long as the New Company Investor owns at least 66% of the Company’s Voting Securities
owned by the New Company Investor as of the Closing Date (and subject to adjustment for stock splits, reclassifications, combinations,
buybacks or similar transactions) and in the event that the New Director (or any Replacement Designee (as defined below), as applicable)
becomes unwilling or unable to serve as a director and ceases to be a director, resigns as a director or is removed as a director,
or for any other reason fails to serve or is not serving as a director at any time prior to the end of the Cooperation Period,
then the members of the New Company Investor shall be entitled to designate, subject to the approval (not to be unreasonably withheld)
of the applicable committee of the Board, a candidate for replacement of such New Director (such replacement, a “Replacement
Designee”). Any Replacement Designee shall qualify as an independent director of the Company under applicable rules of
the SEC, the rules of any stock exchange on which the Company is traded and applicable governance policies of the Company. Following
the approval of a candidate for Replacement Designee by the applicable committee of the Board, the Board shall promptly appoint
such Replacement Designee to the Board. Upon his or her appointment to the Board, such Replacement Designee shall be deemed a New
Director for all purposes under this Agreement.

 

(v)    
So long as the New Director (or any Replacement Designee) serves on the Board
in accordance with the terms of this Agreement, within a reasonable time prior to the filing
with the SEC of the Company’s proxy statement or information statement with
respect to each annual or special meeting of the stockholders of the Company (each, a “Stockholder Meeting”),
the Company shall provide the New Company Investor with the reasonable opportunity
to review the filing and comment on the information contained in such proxy or information statement applicable to the New Company
Investor and the Company shall take into consideration all reasonable comments from the New Company Investor.

 

(b) Additional Agreements.

 

(i)    
The New Company Investor agrees (A) to cause its Affiliates and Representatives (each as defined below) to comply with the
terms of this Agreement and (B) that it shall be responsible for any breach of this Agreement by any such Affiliate or Representative.
A breach of this Agreement by an Affiliate or Representative of the New Company Investor, if such Affiliate or Representative is
not a Party hereto, shall be deemed to occur if such Affiliate or Representative engages in conduct that would constitute a breach
of this Agreement if such Affiliate or Representative were a Party hereto to the same extent as the New Company Investor.

factual statement as required by applicable legal process, subpoena or legal requirement from any governmental authority with competent
jurisdiction over the party from whom information is sought (so long as such request did not arise as a result of action by the
New Company Investor). For the avoidance of doubt, nothing in this Section 2 shall be deemed to limit the exercise in good
faith by a New Director of his fiduciary duties in his capacity as a director of the Company.

Section 14. Non-Disparagement.

 

(a) Subject
to applicable law, each of the Parties covenants and agrees that during the period commencing upon the execution of this Agreement
and ending on the earlier of (i) the conclusion of the Cooperation Period and (ii) such time as the other Party or any of its Affiliates,
Representatives, successors or assigns shall have breached this Section 14(a), neither it nor any of its respective
Affiliates or any Representatives acting on their behalf, or its successors or assigns, shall in any way disparage, slander, attempt
to discredit, call into disrepute, defame, make or cause to be made any statement or announcement that constitutes an ad
hominem attack on the other Party or such other Party’s subsidiaries, Affiliates, successors, assigns, officers
(including any current or former officer of a Party or a Party’s subsidiaries), directors (including any current or former
director of a Party or a Party’s subsidiaries) or Representatives.

legal requirement or as part of a response to a request for information from any governmental authority with jurisdiction over
the Party from whom information is sought.

 

Section 15. Termination.
The obligations of the Parties under this Agreement will terminate on the date that is the end date of the Cooperation Period,
unless another period is specifically set forth herein or otherwise mutually agreed in writing by each Party. The obligations of
the New Company Investor pursuant to Sections 1 and 2 shall terminate in the event that the Company materially breaches
its obligations to the New Company Investor pursuant to Section 1 or the representations and warranties in Section 3
of this Agreement (as they pertain to the Company) and such breach (if capable of being cured) has not been cured within thirty
(30) calendar days following written notice of such breach from the New Company Investor, or, if impossible to cure within 30 calendar
days, the Company has not taken substantive action to correct within thirty (30) calendar days following written notice of such
breach from the New Company Investor. Notwithstanding the foregoing, (a) Section 7 through Section 13,
this Section 15, and Section 16 through Section 20 of this Agreement
will survive the termination of this Agreement; and (b) no termination of this Agreement will relieve any Party of liability for
any breach of this Agreement arising prior to such termination.

 

Section 16. No Waiver.
Any waiver by any Party of a breach of any provision of this Agreement shall not operate as or be construed to be a waiver of any
other breach of such provision or of any breach of any other provision of this Agreement. The failure of a Party to insist upon
strict adherence to any term of this Agreement on one or more occasions shall not be considered a waiver of, or deprive that Party
of the right thereafter to insist upon strict adherence to, that term or any other term of this Agreement.

 

Section 17. Entire
Agreement; Amendments. This Agreement contains the entire understanding of the Parties with respect to the subject matter hereof.
This Agreement may only be amended pursuant to a written agreement executed by the Company, Liquidia and the New Company Investor.

 

Section 18. Successors
and Assigns. This Agreement may not be transferred or assigned by any Party without the prior written consent of the other
Party. Any purported assignment without such consent is null and void. Subject to the foregoing, this Agreement shall be binding

said independent counsel. Each Party and its counsel cooperated and participated in the drafting and preparation of this
Agreement and the documents referred to herein, and any and all drafts relating thereto exchanged among the parties shall be
deemed the work product of all of the Parties and may not be construed against any Party by reason of its drafting or

Agreement against any Party that drafted or prepared it is of no application and is hereby expressly waived by each Party,

Liquidia
to Acquire RareGen, LLC, and Expand Presence in PAH

 

		·	Acquisition Bolsters Liquidia’s Capabilities in Pulmonary Arterial Hypertension (PAH) and Commercial Readiness for
LIQ861, if Approved

 

		·	Two New Directors, - Roger Jeffs, Ph.D. and Paul Manning, to Join Board Concurrent with Acquisition Close

 

RESEARCH TRIANGLE PARK, N.C., June
29, 2020 - Liquidia Technologies, Inc. (NASDAQ: LQDA), a late-stage clinical biopharmaceutical company focused on
the development and commercialization of novel products using its proprietary PRINT® technology, announced
it has entered into a definitive agreement to acquire RareGen, LLC, a portfolio company of PBM Capital, through an all-stock merger.
Liquidia and RareGen will consolidate under a new holding company, to be named Liquidia Corporation, which is expected to trade
on the Nasdaq Capital Market under the ticker symbol “LQDA,” as the successor to Liquidia Technologies. RareGen provides
strategy, investment, and commercialization for rare disease pharmaceutical products. RareGen has a small, targeted sales force
focused on PAH.

 

RareGen acquired the right to promote
Sandoz’s first-to-file generic of Remodulin® (treprostinil) for the treatment of patients with PAH. In March 2019, Sandoz
and RareGen launched their generic treprostinil injection, making it the first generic of Remodulin® to market. Liquidia Corporation
will assume RareGen’s responsibilities under the agreement with Sandoz following closing of the merger transaction.

 

This acquisition reinforces Liquidia’s
commitment to the PAH community and continued pursuit to address the unmet needs of patients and the healthcare professionals who
treat them. The potential introduction of LIQ861 as a more convenient inhaled treprostinil over the currently available inhaled
option, combined with RareGen’s parenteral treprostinil options emphasize Liquidia’s commitment to addressing the patient
continuum of treatment. In addition, these combined entities further enhance the organization’s knowledge base, customer
reach and commercial planning in preparation for the potential launch of LIQ861, if approved.

 

“The acquisition of RareGen creates
tremendous value for Liquidia’s stockholders and, most importantly, patients,” stated Neal Fowler, Chief Executive
Officer of Liquidia. “RareGen offers a knowledgeable team and scalable sales force, coupled with rights to commercialize
an important PAH product that complements Liquidia’s lead product candidate in PAH, LIQ861. The acquisition of RareGen bolsters
Liquidia’s ability to advance much needed treatment options for the PAH community."

 

Following
the closing of the merger transaction, Liquidia and RareGen will be wholly owned operating subsidiaries of Liquidia
Corporation. Under the terms of the merger agreement, Liquidia will acquire 100 percent ownership of RareGen for 6,166,666
shares of Liquidia Corporation common stock. RareGen members are entitled to receive between 1,458,333 and 2,708,333 shares
of additional Liquidia Corporation common stock if certain RareGen net sales thresholds are met in 2021. The transaction was
approved by the boards of directors of Liquidia and RareGen and is expected to close in the fourth quarter of 2020, subject
to customary closing conditions, including approval by Liquidia Technologies stockholders and a registration statement on
Form S-4 being declared effective by the Securities and Exchange Commission (SEC). Under the terms of the merger
agreement, at the close of the transaction Liquidia Technologies stockholders will receive an identical number of shares of
Liquidia Corporation common stock in exchange for their Liquidia Technologies common stock.

At the closing of the merger transaction,
two of RareGen’s current directors, Paul B. Manning, of PBM Capital Group, a current investor in Liquidia and beneficial
owner of a majority of RareGen’s equity, and Roger A. Jeffs, Ph.D., former Co-CEO of United Therapeutics, will join the Liquidia
Corporation Board of Directors and one member of the current Liquidia Board of Directors will resign, resulting in a nine member
board of directors post-closing.

 

“The combined company formed
through this transaction aims to expand access and treatment options for PAH patients,” said Paul Manning, President
and CEO of PBM Capital Group. “We are excited about LIQ861 and think it will offer a more convenient, and portable treatment
option for inhaled Treprostinil. RareGen’s commitment to, and knowledge in the PAH space will amplify Liquidia’s efforts
to support this difficult-to-treat patient group.

 

Certain of Liquidia’s stockholders,
representing approximately 38.5 percent of its current outstanding common stock, have agreed to vote in favor of the merger agreement.

 

Jefferies LLC acted as exclusive financial advisor, and DLA
Piper LLP acted as legal counsel, to Liquidia in connection with the transaction.

Cautionary Statements Regarding
Forward-Looking Statements

 

This communication
contains “forward-looking statements” within the meaning of the federal securities laws, including Section 27A
of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended. In this context,
forward-looking statements often address expected future business and financial performance and financial condition, and often
contain words such as “expect,” “anticipate,” “intend,” “plan,” “believe,”
“seek,” “see,” “will,” “would,” “target,” similar expressions, and
variations or negatives of these words. Forward-looking statements by their nature address matters that are, to different degrees,
uncertain, such as statements about the potential timing or consummation of the proposed merger transaction or the anticipated
benefits thereof, including, without limitation, future financial and operating results. We caution readers that these and other
forward-looking statements are not guarantees of future results and are subject to risks, uncertainties and assumptions that could
cause actual results to differ materially from those expressed in any forward-looking statements. Important risk factors that
may cause such a difference include, but are not limited to risks and uncertainties related to (i) the ability to obtain Liquidia
Technologies stockholder and regulatory approvals, or the possibility that they may delay the merger transaction or that such
regulatory approval may result in the imposition of conditions that could cause the parties to abandon the merger transaction,
(ii) the risk that a condition to closing of the merger transaction may not be satisfied; (iii) the ability of Liquidia Technologies
and RareGen to integrate their businesses successfully and to achieve anticipated cost savings and other synergies, (iv) the possibility
that other anticipated benefits of the proposed merger transaction will not be realized, including without limitation, anticipated
revenues, expenses, earnings and other financial results, and growth and expansion of the new combined company’s operations,
and the anticipated tax treatment, (v) potential litigation relating to the proposed merger transaction that could be instituted
against Liquidia, RareGen or their respective officers or directors, (vi) possible disruptions from the proposed merger transaction
that could harm Liquidia Technologies’ or RareGen’s business, including current plans and operations, (vii) the ability
of Liquidia Technologies or RareGen to retain, attract and hire key personnel, (viii) potential adverse reactions or changes to
relationships with employees, customers, suppliers, licensees, collaborators, business partners or other parties resulting from
the announcement or completion of the merger transaction, (ix) potential business uncertainty, including changes to existing business
relationships, during the pendency of the merger transaction that could affect Liquidia’s and/or RareGen’s financial
performance, (x) certain restrictions during the pendency of the merger transaction that may impact Liquidia Technologies’
or RareGen’s ability to pursue certain business opportunities or strategic transactions, (xi) continued availability of
capital and financing and rating agency actions, (xii) legislative, regulatory and economic developments and (xiii) unpredictability
and severity of catastrophic events, including, but not limited to, global pandemics such as coronavirus, acts of terrorism or
outbreak of war or hostilities, as well as management’s response to any of the aforementioned factors. These risks, as well
as other risks associated with the proposed merger transaction, will be more fully discussed in the proxy statement/prospectus
that will be included in the registration statement on Form S-4 that will be filed with the SEC in connection with the proposed
merger transaction. While the list of factors presented here is, and the list of factors to be presented in the registration statement
on Form S-4 are, considered representative, no such list should be considered to be a complete statement of all potential risks
and uncertainties. Unlisted factors may present significant additional obstacles to the realization of forward-looking statements.
Consequences of material differences in results as compared with those anticipated in the forward-looking statements could include,
among other things, business disruption, operational problems, financial loss, legal liability to third parties and similar risks,
any of which could have a material adverse effect on Liquidia Technologies’ or RareGen’s consolidated financial condition,
results of operations, credit rating or liquidity. Neither Liquidia Technologies nor RareGen assumes any obligation to provide
revisions or updates to any forward-looking statements, whether as a result of new information, future developments or otherwise,
should circumstances change, except as otherwise required by securities and other applicable laws.
