2.             Shelf
Registration.

 

(a)            On
or prior to each Filing Date, the Company shall prepare and file with the Commission a Registration Statement covering the resale
of all of the Registrable Securities that are not then registered on an effective Registration Statement for an offering to be
made on a continuous basis pursuant to Rule 415. Each Registration Statement filed hereunder shall be on Form S-3, if
available, or on Form S-1 if Form S-3 is unavailable, and shall contain (unless otherwise directed by at least 85% in
interest of the Holders) substantially the “Plan of Distribution” attached hereto as Annex A and substantially
the “Selling Stockholder” section attached hereto as Annex B; provided, however, that no
Holder shall be required to be named as an “underwriter” without such Holder’s express prior written consent.
Subject to the terms of this Agreement, the Company shall use its commercially reasonable efforts to cause a Registration Statement
filed under this Agreement (including, without limitation, under Section 3(c)) to be declared effective under the Securities
Act as promptly as possible after the filing thereof, but in any event no later than the applicable Effectiveness Date, and shall
use its commercially reasonable efforts to keep such Registration Statement continuously effective under the Securities Act until
the date that all Registrable Securities covered by such Registration Statement (i) have been sold, thereunder or pursuant
to Rule 144, or (ii) may be sold without volume or manner-of-sale restrictions pursuant to Rule 144 and without
the requirement for the Company to be in compliance with the current public information requirement under Rule 144, as determined
by the counsel to the Company pursuant to a written opinion letter to such effect, addressed and acceptable to the Transfer Agent
and the affected Holders (the “Effectiveness Period”). The Company shall telephonically request effectiveness
of a Registration Statement as of 5:00 p.m. Eastern Time on a Trading Day. The Company shall promptly notify the Holders via
facsimile or by e-mail of the effectiveness of a Registration Statement on the same Trading Day that the Company telephonically
confirms effectiveness with the Commission, which shall be the date requested for effectiveness of such Registration Statement.
The Company shall, by 9:30 a.m. Eastern Time on the Trading Day after the effective date of such Registration Statement, file
a final Prospectus with the Commission as required by Rule 424. Failure to so notify the Holder within one (1) Trading
Day of such notification of effectiveness or failure to file a final Prospectus as foresaid shall be deemed an Event under Section 2(d).

 

(b)            Notwithstanding
the registration obligations set forth in Section 2(a), if the Commission informs the Company that all of the Registrable
Securities cannot, as a result of the application of Rule 415, be registered for resale as a secondary offering on a single
registration statement, the Company agrees to promptly inform each of the Holders thereof and use its commercially reasonable efforts
to file amendments to the Initial Registration Statement as required by the Commission, covering the maximum number of Registrable
Securities permitted to be registered by the Commission, on Form S-3 or such other form available to register for resale the
Registrable Securities as a secondary offering; with respect to filing on Form S-3 or other appropriate form, and subject
to the provisions of Section 2(d) with respect to the payment of liquidated damages; provided, however,
that prior to filing such amendment, the Company shall be obligated to use diligent efforts to advocate with the Commission for
the registration of all of the Registrable Securities in accordance with the SEC Guidance, including without limitation, Compliance
and Disclosure Interpretation 612.09.

 

    4

     

    

 

(c)            Notwithstanding
any other provision of this Agreement and subject to the payment of liquidated damages pursuant to Section 2(d), if the Commission
or any SEC Guidance sets forth a limitation on the number of Registrable Securities permitted to be registered on a particular
Registration Statement as a secondary offering (and notwithstanding that the Company used diligent efforts to advocate with the
Commission for the registration of all or a greater portion of Registrable Securities), unless otherwise directed in writing by
a Holder as to its Registrable Securities, the number of Registrable Securities to be registered on such Registration Statement
will be reduced as follows:

 

		i.	First, the Company shall reduce or eliminate any securities
to be included other than Registrable Securities; and

 

		ii.	Second, the Company shall reduce Registrable Securities (applied,
in the case that some Registrable Securities may be registered, to the Holders on a pro rata basis based on the total number of
Registrable Securities held by such Holders).

 

In
the event of a cutback hereunder, the Company shall give the Holder at least five (5) Trading Days prior written notice along
with the calculations as to such Holder’s allotment. In the event the Company amends the Initial Registration Statement in
accordance with the foregoing, the Company will use its commercially reasonable efforts
to file with the Commission, as promptly as allowed by Commission or SEC Guidance provided to the Company or to registrants of
securities in general, one or more registration statements on Form S-3 or such other form available to register for resale
those Registrable Securities that were not registered for resale on the Initial Registration Statement, as amended.

 

    5

     

    

 

(d)            If:
(i) the Initial Registration Statement is not filed on or prior to its Filing Date (if the Company files the Initial Registration
Statement without affording the Holders the opportunity to review and comment on the same as required by Section 3(a) herein,
the Company shall be deemed to have not satisfied this clause (i)), or (ii) the Company fails to file with the Commission
a request for acceleration of a Registration Statement in accordance with Rule 461 promulgated by the Commission pursuant
to the Securities Act, within five Trading Days of the date that the Company is notified (orally or in writing, whichever is earlier)
by the Commission that such Registration Statement will not be “reviewed” or will not be subject to further review,
or (iii) prior to the effective date of a Registration Statement, the Company fails to file a pre-effective amendment and
otherwise respond in writing to comments made by the Commission in respect of such Registration Statement within ten (10) Trading
Days after the receipt of comments by or notice from the Commission that such amendment is required in order for such Registration
Statement to be declared effective, or (iv) a Registration Statement registering for resale all of the Registrable Securities
is not declared effective by the Commission by the Effectiveness Date of the Initial Registration Statement, or (v) after
the effective date of a Registration Statement, such Registration Statement ceases for any reason to remain continuously effective
as to all Registrable Securities included in such Registration Statement, or the Holders are otherwise not permitted to utilize
the Prospectus therein to resell such Registrable Securities, for more than ten (10) consecutive calendar days or more than
an aggregate of fifteen (15) calendar days (which need not be consecutive calendar days) during any 12-month period (any such failure
or breach being referred to as an “Event”, and for purposes of clauses (i) and (iv), the date on which
such Event occurs, and for purpose of clause (ii) the date on which such five (5) Trading Day period is exceeded, and
for purpose of clause (iii) the date which such ten (10) calendar day period is exceeded, and for purpose of clause (v) the
date on which such ten (10) or fifteen (15) calendar day period, as applicable, is exceeded being referred to as “Event
Date”), then, in addition to any other rights the Holders may have hereunder or under applicable law, on each such Event
Date and on each monthly anniversary of each such Event Date (if the applicable Event shall not have been cured by such date) until
the applicable Event is cured, the Company shall pay to each Holder an amount in cash, as partial liquidated damages and not as
a penalty, equal to the product of 1.0% multiplied by the aggregate Subscription Amount paid by such Holder pursuant to the Purchase
Agreement. The parties agree that the maximum aggregate liquidated damages payable to a Holder under this Agreement shall be 6.0%
of the aggregate Subscription Amount paid by such Holder pursuant to the Purchase Agreement. If the Company fails to pay any partial
liquidated damages pursuant to this Section in full within seven days after the date payable, the Company will pay interest
thereon at a rate of 18% per annum (or such lesser maximum amount that is permitted to be paid by applicable law) to the Holder,
accruing daily from the date such partial liquidated damages are due until such amounts, plus all such interest thereon, are paid
in full. The partial liquidated damages pursuant to the terms hereof shall apply on a daily pro rata basis for any portion of a
month prior to the cure of an Event. Notwithstanding the foregoing, the Company shall not owe any liquidated damages to any Holder
pursuant to this Section 2(d) if, at the time of the Event, such Holder may sell the Registrable Securities held by such
Holder pursuant to Rule 144 without volume restrictions or current public information requirements.

 

(e)            Notwithstanding
anything to the contrary contained herein, in no event shall the Company be permitted to name any Holder or affiliate of a Holder
as any Underwriter without the prior written consent of such Holder.

3.            Registration
Procedures.

 

In connection with
the Company’s registration obligations hereunder, the Company shall:

 

(a)            Not
less than five (5) Trading Days prior to the filing of each Registration Statement and not less than one (1) Trading
Day prior to the filing of any related Prospectus or any amendment or supplement thereto (excluding any document that would be
incorporated or deemed to be incorporated therein by reference), the Company shall (i) furnish to each Holder copies of all
such documents proposed to be filed, which documents (other than those incorporated or deemed to be incorporated by reference)
will be subject to the review of such Holders, and (ii) cause its officers and directors, counsel and independent registered
public accountants to respond to such inquiries as shall be necessary, in the reasonable opinion of respective counsel to each
Holder, to conduct a reasonable investigation within the meaning of the Securities Act. The Company shall not file a Registration
Statement or any such Prospectus or any amendments or supplements thereto to which the Holders of a majority of the Registrable
Securities shall reasonably object in good faith, provided that, the Company is notified of such objection in writing no later
than three (3) Trading Days after the Holders have been so furnished copies of a Registration Statement or one (1) Trading
Day after the Holders have been so furnished copies of any related Prospectus or amendments or supplements thereto. Each Holder
agrees to furnish to the Company a completed questionnaire in the form attached to this Agreement as Annex C (a “Selling
Stockholder Questionnaire”) on a date that is not less than two (2) Trading Days prior to the Filing Date or by
the end of the third (3rd) Trading Day following the date on which such Holder receives draft materials in accordance
with this Section.

 

(b)            (i) Prepare
and file with the Commission such amendments, including post-effective amendments, to a Registration Statement and the Prospectus
used in connection therewith as may be necessary to keep a Registration Statement continuously effective as to the applicable Registrable
Securities for the Effectiveness Period and prepare and file with the Commission such additional Registration Statements in order
to register for resale under the Securities Act all of the Registrable Securities, (ii) cause the related Prospectus to be
amended or supplemented by any required Prospectus supplement (subject to the terms of this Agreement), and, as so supplemented
or amended, to be filed pursuant to Rule 424, (iii) respond as promptly as reasonably possible to any comments received
from the Commission with respect to a Registration Statement or any amendment thereto and provide as promptly as reasonably possible
to the Holders true and complete copies of all correspondence from and to the Commission relating to a Registration Statement (provided
that, the Company shall excise any information contained therein which would constitute material non-public information regarding
the Company or any of its Subsidiaries), and (iv) comply in all material respects with the applicable provisions of the Securities
Act and the Exchange Act with respect to the disposition of all Registrable Securities covered by a Registration Statement during
the applicable period in accordance (subject to the terms of this Agreement) with the intended methods of disposition by the Holders
thereof set forth in such Registration Statement as so amended or in such Prospectus as so supplemented.

 

(c)            If
during the Effectiveness Period, the number of Registrable Securities at any time exceeds 100% of the number of shares of Common
Stock then registered in a Registration Statement, then the Company shall file as soon as reasonably practicable, but in any case
prior to the applicable Filing Date, an additional Registration Statement covering the resale by the Holders of not less than the
number of such Registrable Securities.

 

    7

     

    

 

(d)            Notify
the Holders of Registrable Securities to be sold (which notice shall, pursuant to clauses (iii) through (vi) hereof,
be accompanied by an instruction to suspend the use of the Prospectus until the requisite changes have been made) as promptly as
reasonably possible (and, in the case of (i)(A) below, not less than one (1) Trading Day prior to such filing) and (if
requested by any such Person) confirm such notice in writing no later than one (1) Trading Day following the day: (i)(A) when
a Prospectus or any Prospectus supplement or post-effective amendment to a Registration Statement is proposed to be filed, (B) when
the Commission notifies the Company whether there will be a “review” of such Registration Statement and whenever the
Commission comments in writing on such Registration Statement, or (C) with respect to a Registration Statement or any post-effective
amendment, when the same has become effective; (ii) of any request by the Commission or any other federal or state governmental
authority for amendments or supplements to a Registration Statement or Prospectus or for additional information; (iii) of
the issuance by the Commission or any other federal or state governmental authority of any stop order suspending the effectiveness
of a Registration Statement covering any or all of the Registrable Securities or the initiation of any Proceedings for that purpose;
(iv) of the receipt by the Company of any notification with respect to the suspension of the qualification or exemption from
qualification of any of the Registrable Securities for sale in any jurisdiction, or the initiation or threatening of any Proceeding
for such purpose; (v) of the occurrence of any event or passage of time that makes the financial statements included in a
Registration Statement ineligible for inclusion therein or any statement made in a Registration Statement or Prospectus or any
document incorporated or deemed to be incorporated therein by reference untrue in any material respect or that requires any revisions
to a Registration Statement, Prospectus or other documents so that, in the case of a Registration Statement or the Prospectus,
as the case may be, it will not contain any untrue statement of a material fact or omit to state any material fact required to
be stated therein or necessary to make the statements therein, in light of the circumstances under which they were made, not misleading;
and (vi) of the occurrence or existence of any pending corporate development with respect to the Company that the Company
believes may be material and that, in the determination of the Company, makes it not in the best interest of the Company to allow
continued availability of a Registration Statement or Prospectus, provided, however, that in no event shall any such
notice contain any information which would constitute material, non-public information regarding the Company or any of its Subsidiaries.

 

(e)            Use
its commercially reasonable efforts to avoid the issuance of, or, if issued, obtain the withdrawal of (i) any order stopping
or suspending the effectiveness of a Registration Statement, or (ii) any suspension of the qualification (or exemption from
qualification) of any of the Registrable Securities for sale in any jurisdiction, at the earliest practicable moment.

 

    8

     

    

 

(f)             Furnish
to each Holder, without charge, at least one conformed copy of each such Registration Statement and each amendment thereto, including
financial statements and schedules, all documents incorporated or deemed to be incorporated therein by reference to the extent
requested by such Person, and all exhibits to the extent requested by such Person (including those previously furnished or incorporated
by reference) promptly after the filing of such documents with the Commission; provided, that any such item which is available
on the EDGAR system (or successor thereto) need not be furnished in physical form.

 

(g)            Subject
to the terms of this Agreement, the Company hereby consents to the use of such Prospectus and each amendment or supplement thereto
by each of the selling Holders in connection with the offering and sale of the Registrable Securities covered by such Prospectus
and any amendment or supplement thereto, except after the giving of any notice pursuant to Section 3(d).

 

(h)            Prior
to any resale of Registrable Securities by a Holder, use its commercially reasonable efforts to register or qualify or cooperate
with the selling Holders in connection with the registration or qualification (or exemption from the Registration or qualification)
of such Registrable Securities for the resale by the Holder under the securities or Blue Sky laws of such jurisdictions within
the United States as any Holder reasonably requests in writing, to keep each registration or qualification (or exemption therefrom)
effective during the Effectiveness Period and to do any and all other acts or things reasonably necessary to enable the disposition
in such jurisdictions of the Registrable Securities covered by each Registration Statement; provided, that, the Company shall not
be required to qualify generally to do business in any jurisdiction where it is not then so qualified, subject the Company to any
material tax in any such jurisdiction where it is not then so subject or file a general consent to service of process in any such
jurisdiction.

 

(i)            If
requested by a Holder, cooperate with such Holder to facilitate the timely preparation and delivery of certificates representing
Registrable Securities to be delivered to a transferee pursuant to a Registration Statement, which certificates shall be free,
to the extent permitted by the Purchase Agreement, of all restrictive legends, and to enable such Registrable Securities to be
in such denominations and registered in such names as any such Holder may request.

 

    9

     

    

 

(j)             Upon
the occurrence of any event contemplated by Section 3(d), as promptly as reasonably possible under the circumstances taking
into account the Company’s good faith assessment of any adverse consequences to the Company and its stockholders of the premature
disclosure of such event, prepare a supplement or amendment, including a post-effective amendment, to a Registration Statement
or a supplement to the related Prospectus or any document incorporated or deemed to be incorporated therein by reference, and file
any other required document so that, as thereafter delivered, neither a Registration Statement nor such Prospectus will contain
an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the
statements therein, in light of the circumstances under which they were made, not misleading. If the Company notifies the Holders
in accordance with clauses (iii) through (vi) of Section 3(d) above to suspend the use of any Prospectus until
the requisite changes to such Prospectus have been made, then the Holders shall suspend use of such Prospectus. The Company will
use its commercially reasonable efforts to ensure that the use of the Prospectus may be resumed as promptly as is practicable.
The Company shall be entitled to exercise its right under this Section 3(j) to suspend the availability of a Registration
Statement and Prospectus, subject to the payment of partial liquidated damages otherwise required pursuant to Section 2(d),
for a period not to exceed 60 calendar days (which need not be consecutive days) in any 12-month period.

 

(k)            Otherwise
use commercially reasonable efforts to comply with all applicable rules and regulations of the Commission under the Securities
Act and the Exchange Act, including, without limitation, Rule 172 under the Securities Act, file any final Prospectus, including
any supplement or amendment thereof, with the Commission pursuant to Rule 424 under the Securities Act, promptly inform the
Holders in writing if, at any time during the Effectiveness Period, the Company does not satisfy the conditions specified in Rule 172
and, as a result thereof, the Holders are required to deliver a Prospectus in connection with any disposition of Registrable Securities
and take such other actions as may be reasonably necessary to facilitate the registration of the Registrable Securities hereunder.

 

(l)            The
Company may require each selling Holder to furnish to the Company a certified statement as to the number of shares of Common Stock
beneficially owned by such Holder and, if required by the Commission, the natural persons thereof that have voting and dispositive
control over the shares. During any periods that the Company is unable to meet its obligations hereunder with respect to the registration
of the Registrable Securities solely because any Holder fails to furnish such information within three Trading Days of the Company’s
request, any liquidated damages that are accruing at such time as to such Holder only shall be tolled and any Event that may otherwise
occur solely because of such delay shall be suspended as to such Holder only, until such information is delivered to the Company.

 

    10

     

    

 

4.              Registration
Expenses. All fees and expenses incident to the performance of or compliance with, this Agreement by the Company shall be borne
by the Company whether or not any Registrable Securities are sold pursuant to a Registration Statement. The fees and expenses referred
to in the foregoing sentence shall include, without limitation, (i) all registration and filing fees (including, without limitation,
fees and expenses of the Company’s counsel and independent registered public accountants) (A) with respect to filings
made with the Commission, (B) with respect to filings required to be made with any Trading Market on which the Common Stock
is then listed for trading, and (C) in compliance with applicable state securities or Blue Sky laws reasonably agreed to by
the Company in writing (including, without limitation, fees and disbursements of counsel for the Company in connection with Blue
Sky qualifications or exemptions of the Registrable Securities); (ii) printing expenses (including, without limitation, expenses
of printing certificates for Registrable Securities); (iii) messenger, telephone and delivery expenses; (iv) fees and
disbursements of counsel for the Company; (v) Securities Act liability insurance, if the Company so desires such insurance;
and (vi) fees and expenses of all other Persons retained by the Company in connection with the consummation of the transactions
contemplated by this Agreement. In addition, the Company shall be responsible for all of its internal expenses incurred in connection
with the consummation of the transactions contemplated by this Agreement (including, without limitation, all salaries and expenses
of its officers and employees performing legal or accounting duties), the expense of any annual audit and the fees and expenses
incurred in connection with the listing of the Registrable Securities on any securities exchange as required hereunder. In no event
shall the Company be responsible for any broker or similar commissions of any Holder or, except to the extent provided for in the
Transaction Documents, any legal fees or other costs of the Holders.

 

5.              Indemnification.

 

(a)            Indemnification
by the Company. The Company shall, notwithstanding any termination of this Agreement, indemnify and hold harmless each Holder,
the officers, directors, members, partners, agents, brokers (including brokers who offer and sell Registrable Securities as principal
as a result of a pledge or any failure to perform under a margin call of Common Stock), investment advisors and employees (and
any other Persons with a functionally equivalent role of a Person holding such titles, notwithstanding a lack of such title or
any other title) of each of them, each Person who controls any such Holder (within the meaning of Section 15 of the Securities
Act or Section 20 of the Exchange Act) and the officers, directors, members, stockholders, partners, agents and employees
(and any other Persons with a functionally equivalent role of a Person holding such titles, notwithstanding a lack of such title
or any other title) of each such controlling Person, to the fullest extent permitted by applicable law, from and against any and
all losses, claims, damages, liabilities, costs (including, without limitation, reasonable attorneys’ fees) and expenses
(collectively, “Losses”), as incurred, arising out of or relating to (1) any untrue or alleged untrue statement
of a material fact contained in a Registration Statement, any Prospectus or any form of prospectus or in any amendment or supplement
thereto or in any preliminary prospectus, or arising out of or relating to any omission or alleged omission of a material fact
required to be stated therein or necessary to make the statements therein (in the case of any Prospectus or supplement thereto,
in light of the circumstances under which they were made) not misleading, or (2) any violation or alleged violation by the
Company of the Securities Act, the Exchange Act or any state securities law, or any rule or regulation thereunder, in connection
with the performance of its obligations under this Agreement, except to the extent, but only to the extent, that (i) such
untrue statements or omissions are based solely upon information regarding such Holder furnished in writing to the Company by such
Holder expressly for use therein, or to the extent that such information relates to such Holder or such Holder’s proposed
method of distribution of Registrable Securities and was reviewed and expressly approved in writing by such Holder expressly for
use in a Registration Statement, such Prospectus or in any amendment or supplement thereto (it being understood that the Holder
has approved Annex A hereto for this purpose), or (ii) in the case of an occurrence of an event of the type specified in Section 3(d)(iii)-(vi),
the use by such Holder of an outdated, defective or otherwise unavailable Prospectus after the Company has notified such Holder
in writing that the Prospectus is outdated, defective or otherwise unavailable for use by such Holder and prior to the receipt
by such Holder of the Advice contemplated in Section 6(d), but only if and to the extent that following the receipt of the
Advice the misstatement or omission giving rise to such Loss would have been corrected. The Company shall notify the Holders promptly
of the institution or assertion of any Proceeding arising from or in connection with the transactions contemplated by this Agreement
of which the Company is aware. Such indemnity shall remain in full force and effect regardless of any investigation made by or
on behalf of such indemnified person and shall survive the transfer of any Registrable Securities by any of the Holders in accordance
with Section 6(h).

 

    11

by Holders. Each Holder shall, severally and not jointly, indemnify and hold harmless the Company, its directors, officers,
agents and employees, each Person who controls the Company (within the meaning of Section 15 of the Securities Act and Section 20
of the Exchange Act), and the directors, officers, agents or employees of such controlling Persons, to the fullest extent permitted
by applicable law, from and against all Losses, as incurred, to the extent based solely upon: any untrue or alleged untrue statement
of a material fact contained in any Registration Statement, any Prospectus, or in any amendment or supplement thereto or in any
preliminary prospectus, or arising out of or relating to any omission or alleged omission of a material fact required to be stated
therein or necessary to make the statements therein (in the case of any Prospectus or supplement thereto, in light of the circumstances
under which they were made) not misleading (i) to the extent, but only to the extent, that such untrue statement or omission
is contained in any information so furnished in writing by such Holder to the Company expressly for inclusion in such Registration
Statement or such Prospectus, or (ii) to the extent, but only to the extent, that such information relates to such Holder’s
information provided in the Selling Stockholder Questionnaire or the proposed method of distribution of Registrable Securities
and was reviewed and expressly approved in writing by such Holder expressly for use in a Registration Statement (it being understood
that the Holder has approved Annex A hereto for this purpose), such Prospectus or in any amendment or supplement thereto, or (iii) in
the case of an occurrence of an event of the type specified in Section 3(d)(iii)-(vi), to the extent, but only to the extent,
related to the use by such Holder of an outdated, defective or otherwise unavailable Prospectus after the Company has notified
such Holder in writing that the Prospectus is outdated, defective or otherwise unavailable for use by such Holder and prior to
the receipt by such Holder of the Advice contemplated in Section 6(d), but only if and to the extent that following the receipt
of the Advice the misstatement or omission giving rise to such Loss would have been corrected. In no event shall the liability
of a selling Holder be greater in amount than the dollar amount of the proceeds (net of all expenses paid by such Holder in connection
with any claim relating to this Section 5 and the amount of any damages such Holder has otherwise been required to pay by
reason of such untrue statement or omission) received by such Holder upon the sale of the Registrable Securities included in the
Registration Statement giving rise to such indemnification obligation.

 

    12

     

    

 

(c)            Conduct
of Indemnification Proceedings. If any Proceeding shall be brought or asserted against any Person entitled to indemnity hereunder
(an “Indemnified Party”), such Indemnified Party shall promptly notify the Person from whom indemnity is sought
(the “Indemnifying Party”) in writing, and the Indemnifying Party shall have the right to assume the defense
thereof, including the employment of counsel reasonably satisfactory to the Indemnified Party and the payment of all fees and expenses
incurred in connection with defense thereof; provided, that, the failure of any Indemnified Party to give such notice shall not
relieve the Indemnifying Party of its obligations or liabilities pursuant to this Agreement, except (and only) to the extent that
it shall be finally determined by a court of competent jurisdiction (which determination is not subject to appeal or further review)
that such failure shall have materially and adversely prejudiced the Indemnifying Party.

 

An Indemnified
Party shall have the right to employ separate counsel in any such Proceeding and to participate in the defense thereof, but the
fees and expenses of such counsel shall be at the expense of such Indemnified Party or Parties unless: (1) the Indemnifying
Party has agreed in writing to pay such fees and expenses, (2) the Indemnifying Party shall have failed promptly to assume
the defense of such Proceeding and to employ counsel reasonably satisfactory to such Indemnified Party in any such Proceeding,
or (3) the named parties to any such Proceeding (including any impleaded parties) include both such Indemnified Party and
the Indemnifying Party, and counsel to the Indemnified Party shall reasonably believe that a material conflict of interest is likely
to exist if the same counsel were to represent such Indemnified Party and the Indemnifying Party (in which case, if such Indemnified
Party notifies the Indemnifying Party in writing that it elects to employ separate counsel at the expense of the Indemnifying Party,
the Indemnifying Party shall not have the right to assume the defense thereof and the reasonable fees and expenses of no more than
one separate counsel shall be at the expense of the Indemnifying Party). The Indemnifying Party shall not be liable for any settlement
of any such Proceeding effected without its written consent, which consent shall not be unreasonably withheld or delayed. No Indemnifying
Party shall, without the prior written consent of the Indemnified Party, effect any settlement of any pending Proceeding in respect
of which any Indemnified Party is a party, unless such settlement includes an unconditional release of such Indemnified Party from
all liability on claims that are the subject matter of such Proceeding.

 

    13

     

    

 

Subject to
the terms of this Agreement, all reasonable fees and expenses of the Indemnified Party (including reasonable fees and expenses
to the extent incurred in connection with investigating or preparing to defend such Proceeding in a manner not inconsistent with
this Section) shall be paid to the Indemnified Party, as incurred, within ten Trading Days of written notice thereof to the Indemnifying
Party; provided, that, the Indemnified Party shall promptly reimburse the Indemnifying Party for that portion of such fees and
expenses applicable to such actions for which such Indemnified Party is finally determined by a court of competent jurisdiction
(which determination is not subject to appeal or further review) not to be entitled to indemnification hereunder.

 

(d)            Contribution.
If the indemnification under Section 5(a) or 5(b) is unavailable to an Indemnified Party or insufficient to hold
an Indemnified Party harmless for any Losses, then each Indemnifying Party shall contribute to the amount paid or payable by such
Indemnified Party, in such proportion as is appropriate to reflect the relative fault of the Indemnifying Party and Indemnified
Party in connection with the actions, statements or omissions that resulted in such Losses as well as any other relevant equitable
considerations. The relative fault of such Indemnifying Party and Indemnified Party shall be determined by reference to, among
other things, whether any action in question, including any untrue or alleged untrue statement of a material fact or omission or
alleged omission of a material fact, has been taken or made by, or relates to information supplied by, such Indemnifying Party
or Indemnified Party, and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent
such action, statement or omission. The amount paid or payable by a party as a result of any Losses shall be deemed to include,
subject to the limitations set forth in this Agreement, any reasonable attorneys’ or other fees or expenses incurred by such
party in connection with any Proceeding to the extent such party would have been indemnified for such fees or expenses if the indemnification
provided for in this Section was available to such party in accordance with its terms.

 

The parties
hereto agree that it would not be just and equitable if contribution pursuant to this Section 5(d) were determined by
pro rata allocation or by any other method of allocation that does not take into account the equitable considerations referred
to in the immediately preceding paragraph. In no event shall the contribution obligation of a Holder of Registrable Securities
be greater in amount than the dollar amount of the proceeds (net of all expenses paid by such Holder in connection with any claim
relating to this Section 5 and the amount of any damages such Holder has otherwise been required to pay by reason of such
untrue or alleged untrue statement or omission or alleged omission) received by it upon the sale of the Registrable Securities
giving rise to such contribution obligation.

 

    14

     

    

 

The indemnity
and contribution agreements contained in this Section are in addition to any liability that the Indemnifying Parties may have
to the Indemnified Parties.

 

6.             Miscellaneous.

 

(a)           Remedies.
In the event of a breach by the Company or by a Holder of any of their respective obligations under this Agreement, each Holder
or the Company, as the case may be, in addition to being entitled to exercise all rights granted by law and under this Agreement,
including recovery of damages, shall be entitled to specific performance of its rights under this Agreement. Each of the Company
and each Holder agrees that monetary damages may not provide adequate compensation for any losses incurred by reason of a breach
by it of any of the provisions of this Agreement and hereby further agrees that, in the event of any action for specific performance
in respect of such breach, it shall not assert or shall waive the defense that a remedy at law would be adequate.

 

(b)           No
Piggyback on Registrations; Prohibition on Filing Other Registration Statements. Except as set forth on Schedule 6(b) attached
hereto, neither the Company nor any of its security holders (other than the Holders in such capacity pursuant hereto) may include
securities of the Company in any Registration Statements other than the Registrable Securities. The Company shall not file any
other registration statements (other than on Form S-8) until all Registrable Securities are registered pursuant to a Registration
Statement that is declared effective by the Commission, provided that this Section 6(b) shall not prohibit the Company
from filing amendments to registration statements filed prior to the date of this Agreement.

 

(c)           [Reserved]

 

(d)           Discontinued
Disposition. By its acquisition of Registrable Securities, each Holder agrees that, upon receipt of a notice from the Company
of the occurrence of any event of the kind described in Section 3(d)(iii) through (vi), such Holder will forthwith discontinue
disposition of such Registrable Securities under a Registration Statement until it is advised in writing (the “Advice”)
by the Company that the use of the applicable Prospectus (as it may have been supplemented or amended) may be resumed. The Company
will use its commercially reasonable efforts to ensure that the use of the Prospectus may be resumed as promptly as is practicable.
The Company agrees and acknowledges that any periods during which the Holder is required to discontinue the disposition of the
Registrable Securities hereunder shall be subject to the provisions of Section 2(d).

 

    15

     

    

 

(e)           Piggy-Back
Registrations. If, at any time during the Effectiveness Period, there is not an effective Registration Statement covering all
of the Registrable Securities and the Company shall determine to prepare and file with the Commission a registration statement
relating to an offering for its own account or the account of others under the Securities Act of any of its equity securities,
other than on Form S-4 or Form S-8 (each as promulgated under the Securities Act) or their then equivalents relating
to equity securities to be issued solely in connection with any acquisition of any entity or business or equity securities issuable
in connection with the Company’s stock option or other employee benefit plans, then the Company shall deliver to each Holder
a written notice of such determination and, if within fifteen days after the date of the delivery of such notice, any such Holder
shall so request in writing, the Company shall include in such registration statement all or any part of such Registrable Securities
such Holder requests to be registered; provided, however, that the Company shall not be required to register any Registrable Securities
pursuant to this Section 6(e) that are eligible for resale pursuant to Rule 144 (without volume restrictions or
current public information requirements) promulgated by the Commission pursuant to the Securities Act or that are the subject of
a then effective Registration Statement that is available for resales or other dispositions by such Holder.

 

(f)            Amendments
and Waivers. The provisions of this Agreement, including the provisions of this sentence, may not be amended, modified or supplemented,
and waivers or consents to departures from the provisions hereof may not be given, unless the same shall be in writing and signed
by the Company and the Holders of a majority of the then outstanding Registrable Securities (for purposes of clarification, this
includes any Registrable Securities issuable upon exercise or conversion of any Security), provided that, if any amendment, modification
or waiver disproportionately and adversely impacts a Holder (or group of Holders), the consent of such disproportionately impacted
Holder (or group of Holders) shall be required. If a Registration Statement does not register all of the Registrable Securities
pursuant to a waiver or amendment done in compliance with the previous sentence, then the number of Registrable Securities to be
registered for each Holder shall be reduced pro rata among all Holders and each Holder shall have the right to designate which
of its Registrable Securities shall be omitted from such Registration Statement. Notwithstanding the foregoing, a waiver or consent
to depart from the provisions hereof with respect to a matter that relates exclusively to the rights of a Holder or some Holders
and that does not directly or indirectly affect the rights of other Holders may be given only by such Holder or Holders of all
of the Registrable Securities to which such waiver or consent relates; provided, however, that the provisions of
this sentence may not be amended, modified, or supplemented except in accordance with the provisions of the first sentence of this
Section 6(f). No consideration shall be offered or paid to any Person to amend or consent to a waiver or modification of any
provision of this Agreement unless the same consideration also is offered to all of the parties to this Agreement.

 

(g)           Notices.
Any and all notices or other communications or deliveries required or permitted to be provided hereunder shall be delivered as
set forth in the Purchase Agreement.

 

    16

     

    

 

(h)           Successors
and Assigns. This Agreement shall inure to the benefit of and be binding upon the successors and permitted assigns of each
of the parties and shall inure to the benefit of each Holder. The Company may not assign (except by merger) its rights or obligations
hereunder without the prior written consent of all of the Holders of the then outstanding Registrable Securities. Each Holder may
assign their respective rights hereunder in the manner and to the Persons as permitted under Section 5.8 of the Purchase Agreement.

 

(i)            No
Inconsistent Agreements. Neither the Company nor any of its Subsidiaries has entered, as of the date hereof, nor shall the
Company or any of its Subsidiaries, on or after the date of this Agreement, enter into any agreement with respect to its securities,
that would have the effect of impairing the rights granted to the Holders in this Agreement or otherwise conflicts with the provisions
hereof. Except as set forth on Schedule 6(i), neither the Company nor any of its Subsidiaries has previously entered into
any agreement granting any registration rights with respect to any of its securities to any Person that have not been satisfied
in full.

 

(j)            Execution
and Counterparts. This Agreement may be executed in two or more counterparts, all of which when taken together shall be considered
one and the same agreement and shall become effective when counterparts have been signed by each party and delivered to the other
party, it being understood that both parties need not sign the same counterpart. In the event that any signature is delivered by
facsimile transmission or by e-mail delivery of a “.pdf” format data file, such signature shall create a valid and
binding obligation of the party executing (or on whose behalf such signature is executed) with the same force and effect as if
such facsimile or “.pdf” signature page were an original thereof.

 

(k)            Governing
Law. All questions concerning the construction, validity, enforcement and interpretation of this Agreement shall be determined
in accordance with the provisions of the Purchase Agreement.

 

(l)            Cumulative
Remedies. The remedies provided herein are cumulative and not exclusive of any other remedies provided by law.

 

(m)          Severability.
If any term, provision, covenant or restriction of this Agreement is held by a court of competent jurisdiction to be invalid, illegal,
void or unenforceable, the remainder of the terms, provisions, covenants and restrictions set forth herein shall remain in full
force and effect and shall in no way be affected, impaired or invalidated, and the parties hereto shall use their commercially
reasonable efforts to find and employ an alternative means to achieve the same or substantially the same result as that contemplated
by such term, provision, covenant or restriction. It is hereby stipulated and declared to be the intention of the parties that
they would have executed the remaining terms, provisions, covenants and restrictions without including any of such that may be
hereafter declared invalid, illegal, void or unenforceable.

 

    17

     

    

 

(n)           Headings.
The headings in this Agreement are for convenience only, do not constitute a part of the Agreement and shall not be deemed to limit
or affect any of the provisions hereof.

 

(o)           Independent
Nature of Holders’ Obligations and Rights. The obligations of each Holder hereunder are several and not joint with the
obligations of any other Holder hereunder, and no Holder shall be responsible in any way for the performance of the obligations
of any other Holder hereunder. Nothing contained herein or in any other agreement or document delivered at any closing, and no
action taken by any Holder pursuant hereto or thereto, shall be deemed to constitute the Holders as a partnership, an association,
a joint venture or any other kind of group or entity, or create a presumption that the Holders are in any way acting in concert
or as a group or entity with respect to such obligations or the transactions contemplated by this Agreement or any other matters,
and the Company acknowledges that the Holders are not acting in concert or as a group, and the Company shall not assert any such
claim, with respect to such obligations or transactions. Each Holder shall be entitled to protect and enforce its rights, including
without limitation the rights arising out of this Agreement, and it shall not be necessary for any other Holder to be joined as
an additional party in any proceeding for such purpose. The use of a single agreement with respect to the obligations of the Company
contained was solely in the control of the Company, not the action or decision of any Holder, and was done solely for the convenience
of the Company and not because it was required or requested to do so by any Holder. It is expressly understood and agreed that
each provision contained in this Agreement is between the Company and a Holder, solely, and not between the Company and the Holders
collectively and not between and among Holders.

Annex A

 

Plan of Distribution

 

Each Selling Stockholder
(the “Selling Stockholders”) of the securities and any of their pledgees, assignees and successors-in-interest
may, from time to time, sell any or all of their securities covered hereby on the Nasdaq Stock Market or any other stock exchange,
market or trading facility on which the securities are traded or in private transactions. These sales may be at fixed or negotiated
prices. A Selling Stockholder may use any one or more of the following methods when selling securities:

 

		·	ordinary brokerage transactions and transactions in which the broker-dealer solicits purchasers;

 

		·	block trades in which the broker-dealer will attempt to sell the securities as agent but may position and resell a portion
of the block as principal to facilitate the transaction;

 

		·	purchases by a broker-dealer as principal and resale by the broker-dealer for its account;

 

		·	an exchange distribution in accordance with the rules of the applicable exchange;

 

		·	privately negotiated transactions;

 

		·	settlement of short sales;

 

		·	in transactions through broker-dealers that agree with the Selling Stockholders to sell a specified number of such securities
at a stipulated price per security;

 

		·	through the writing or settlement of options or other hedging transactions, whether through an options exchange or otherwise;

 

		·	a combination of any such methods of sale; or

 

		·	any other method permitted pursuant to applicable law.

 

The Selling Stockholders
may also sell securities under Rule 144 or any other exemption from registration under the Securities Act of 1933, as amended
(the “Securities Act”), if available, rather than under this prospectus.

 

Broker-dealers engaged
by the Selling Stockholders may arrange for other broker-dealers to participate in sales. Broker-dealers may receive commissions
or discounts from the Selling Stockholders (or, if any broker-dealer acts as agent for the purchaser of securities, from the purchaser)
in amounts to be negotiated, but, except as set forth in a supplement to this Prospectus, in the case of an agency transaction
not in excess of a customary brokerage commission in compliance with FINRA Rule 2440; and in the case of a principal transaction
a markup or markdown in compliance with FINRA IM-2440.

 

    

     

    

 

In connection with
the sale of the securities or interests therein, the Selling Stockholders may enter into hedging transactions with broker-dealers
or other financial institutions, which may in turn engage in short sales of the securities in the course of hedging the positions
they assume. The Selling Stockholders may also sell securities short and deliver these securities to close out their short positions,
or loan or pledge the securities to broker-dealers that in turn may sell these securities. The Selling Stockholders may also enter
into option or other transactions with broker-dealers or other financial institutions or create one or more derivative securities
which require the delivery to such broker-dealer or other financial institution of securities offered by this prospectus, which
securities such broker-dealer or other financial institution may resell pursuant to this prospectus (as supplemented or amended
to reflect such transaction).

 

The Selling Stockholders
and any broker-dealers or agents that are involved in selling the securities may be deemed to be “underwriters” within
the meaning of the Securities Act in connection with such sales. In such event, any commissions received by such broker-dealers
or agents and any profit on the resale of the securities purchased by them may be deemed to be underwriting commissions or discounts
under the Securities Act. Each Selling Stockholder has informed the Company that it does not have any written or oral agreement
or understanding, directly or indirectly, with any person to distribute the securities.

 

The Company is required
to pay certain fees and expenses incurred by the Company incident to the registration of the securities. The Company has agreed
to indemnify the Selling Stockholders against certain losses, claims, damages and liabilities, including liabilities under the
Securities Act.

 

We agreed to keep this
prospectus effective until the earlier of (i) the date on which the securities may be resold by the Selling Stockholders without
registration and without regard to any volume or manner-of-sale limitations by reason of Rule 144, without the requirement
for the Company to be in compliance with the current public information under Rule 144 under the Securities Act or any other
rule of similar effect, or (ii) all of the securities have been sold pursuant to this prospectus or Rule 144 under
the Securities Act or any other rule of similar effect. The resale securities will be sold only through registered or licensed
brokers or dealers if required under applicable state securities laws. In addition, in certain states, the resale securities covered
hereby may not be sold unless they have been registered or qualified for sale in the applicable state or an exemption from the
registration or qualification requirement is available and is complied with.

 

    2

     

    

 

Under applicable rules and
regulations under the Exchange Act, any person engaged in the distribution of the resale securities may not simultaneously engage
in market making activities with respect to the common stock for the applicable restricted period, as defined in Regulation M,
prior to the commencement of the distribution. In addition, the Selling Stockholders will be subject to applicable provisions of
the Exchange Act and the rules and regulations thereunder, including Regulation M, which may limit the timing of purchases
and sales of the common stock by the Selling Stockholders or any other person. We will make copies of this prospectus available
to the Selling Stockholders and have informed them of the need to deliver a copy of this prospectus to each purchaser at or prior
to the time of the sale (including by compliance with Rule 172 under the Securities Act).

Annex B

 

Selling Stockholders

 

The common stock being
offered by the Selling Stockholders are those previously issued to the Selling Stockholders, and those issuable to the Selling
Stockholders, upon conversion of the preferred shares. For additional information regarding the issuances of those shares of common
stock and preferred stock, see "Private Placement of Common Shares and Preferred Stock" above. We are registering the
shares of common stock in order to permit the Selling Stockholders to offer the shares for resale from time to time. Except for
the ownership of the shares of common stock, the preferred stock and the purchase of securities in prior financings in the case
of some Selling Stockholders, the Selling Stockholders have not had any material relationship with us within the past three years.

 

The table below lists
the Selling Stockholders and other information regarding the beneficial ownership of the shares of common stock by each of the
Selling Stockholders. The second column lists the number of shares of common stock beneficially owned by each Selling Stockholder,
based on its ownership of the shares of common stock and preferred stock, assuming conversion of the preferred stock held by the
Selling Stockholders.

 

The third column lists
the shares of common stock being offered by this prospectus by the Selling Stockholders.

 

In accordance with
the terms of a registration rights agreement with the Selling Stockholders, this prospectus generally covers the resale of the
sum of (i) the number of shares of common stock issued to the Selling Stockholders in the private placement and (ii) the
maximum number of shares of common stock issuable upon conversion of the preferred stock, determined as if the outstanding shares
of preferred stock were converted in full as of the trading day immediately preceding the date this registration statement was
initially filed with the SEC, each as of the trading day immediately preceding the applicable date of determination and all subject
to adjustment as provided in the registration right agreement, without regard to any limitations on the conversion of the shares
of preferred stock.

 

The fourth column assumes
the sale of all of the shares offered by the Selling Stockholders pursuant to this prospectus.

 

Under the terms of
the preferred stock, a Selling Stockholder may not convert the shares of preferred stock to the extent such conversion would cause
such Selling Stockholder, together with its affiliates and attribution parties, to beneficially own a number of shares of common
stock which would exceed 4.99% (or at the election of the Selling Stockholder, 9.99%) of our then outstanding common stock following
such conversion, excluding for purposes of such determination shares of common stock issuable upon conversion of the preferred
stock which have not been converted. The number of shares in the second column does not reflect this limitation. The Selling Stockholders
may sell all, some or none of their shares in this offering. See "Plan of Distribution."

RECITALS:

 

WHEREAS, because of the liquidity
constraints the General Partner and the Company are facing as a result of the coronavirus pandemic, they have been engaging in
ongoing discussions with the Initial Preferred LP regarding strategic and liquidity alternatives, and the failure of these discussions,
as well as the potential consequences of the exercise of related rights or other resulting actions that could be taken by the Initial
Preferred LP, or the failure to obtain additional capital from another source, could materially and adversely affect the General
Partner and the Company; and

 

WHEREAS, in order to assist in facilitating
the successful outcome of these discussions, the General Partner and the Initial Preferred LP desire to amend the Partnership
Agreement to convert the Cash C Cash Distribution Amount payable on December 31, 2020 into distributions payable in additional
Class C Units.

 

     

     

    

 

NOW, THEREFORE, in consideration
of the premises made hereunder, and for good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged,
the General Partner and the Initial Limited Partner, intending to be legally bound, hereby agree as follows:

 

1.             Amendments.

 

(a)            The
defined term “Class C Cash Distribution Amount” in the Partnership Agreement is hereby amended and
restated in its entirety as follows:

 

“Class C Cash Distribution
Amount” means, with respect to a Class C Unit and as of any Distribution Date (other than the Distribution Date

Preference, accrued on the basis of twelve (12) thirty (30)-day months and a three hundred sixty (360)-day year compounding quarterly
commencing on the Issue Date for such Class C Unit, and accruing on each Distribution Date (other than the Distribution Date
occurring on December 31, 2020) whether or not declared and whether or not there are profits, surplus, Available Cash or other
Legally Available Funds of the Company for the payment of such amounts; provided, that, subject to the delivery by the Company
of the 12/31/20 PIK Distribution Amount to the Holders of Class C Units, (i) no Class C Cash Distribution Amount
shall accrue or become payable on the Distribution Date occurring on December 31, 2020 and for the Quarter ended thereon,
and (ii) any failure by the Company to pay any amounts with respect to the Class C Cash Distribution Amount on the Distribution
Date occurring on December 31, 2020 shall not be a Material Breach; provided, further, for the avoidance of
doubt, that the Class C Cash Distribution Amount calculated in respect of the Distribution Date occurring on March 31,
2021 shall take into account all of the Class C Units issued in respect of the 12/31/20 PIK Distribution Amount (including
the 3/31/21 Redeemed Units, prior to giving effect to the redemption required pursuant to Section 16.5(a)(iii)); provided,
further, that if the full amount of the Class C Cash Distribution Amount is not distributed with respect to any Class C
Unit on any Distribution Date (other than the Distribution Date occurring on December 31, 2020) for any reason, including
if Legally Available Funds or Available Cash are not available therefor, or if a Recapitalization Agreement is not executed and
delivered on or before the Distribution Date occurring on March 31, 2021 and the Company does not redeem the 3/31/21 Redeemed
Units because it is not required to do so pursuant the proviso to the first sentence of Section 16.5(a)(iii), the Class C
Cash Distribution Amount for such Class C Unit (including any 3/31/21 Redeemed Units that has not been redeemed) shall thereafter
accrue at the rate of 10.0% per annum on such Class C Unit’s Liquidation Preference (which will include any accrued
and unpaid Class C Cash Distribution Amounts) from and after such Distribution Date until the accrued and unpaid Class C
Cash Distribution Amounts with respect to such Class C Unit is reduced to zero or, if applicable, such Class C Unit is
redeemed.

 

(b)            The
defined term “Full Redemption Amount” in the Partnership Agreement is hereby amended and restated in
its entirety as follows:

 

“Full Redemption Amount”
means the aggregate amounts due pursuant to the applicable Notices of Redemption delivered to the Company by Holders of Class C
Units or OP Units or required to be paid with respect to any redemption pursuant to Section 16.5(a)(iii), and all other amounts

as well as, as the context requires, a Specified Redemption Date pursuant to Section 8.6(a).

 

(e)            The
following new defined terms are hereby added to the Partnership Agreement:

    3

     

    

 

In addition to the Class C Cash Distribution
Amount and subject to Section 15.14, with respect to each Class C Unit and as of any Distribution Date, each Holder of
Class C Units shall be entitled to receive, and the Company shall deliver, in the form of additional Class C Units, distributions
in an amount accrued at the rate of 5.0% per annum on such Class C Unit’s Liquidation Preference, accrued on the basis
of twelve (12) thirty (30)-day months and a three hundred sixty (360)-day year compounding quarterly commencing on the Issue Date
for such Class C Unit and payable on each Distribution Date (such amount, the “PIK Distribution Amount”
and such distributions, the “PIK Distributions”); provided, that, as of the Distribution Date occurring
on December 31, 2020, each Holder of Class C Units shall instead be entitled to receive, and the Company shall deliver,
in the form of additional Class C Units, PIK Distributions in an amount accrued at the rate of 12.5% per annum on such Class C
Unit’s Liquidation Preference, accrued on the basis of twelve (12) thirty (30)-day months and a three hundred sixty (360)-day
year compounding quarterly for such Class C Unit and payable on such Distribution Date (such amount, the “12/31/20
PIK Distribution Amount”); provided, further, for the avoidance of doubt, that the PIK Distribution Amount
and PIK Distributions calculated in respect of the Distribution Date occurring on March 31, 2021 shall take into account all
of the Class C Units issued in respect of the 12/31/20 PIK Distribution Amount (including the 3/31/21 Redeemed Units, prior
to giving effect to the redemption required pursuant to Section 16.5(a)(iii)). The number of Class C Units, which for
the avoidance of doubt, may include a fraction of a Class C Unit, delivered in respect of the PIK Distribution Amount on any
Distribution Date shall be equal to the number obtained by dividing the PIK Distribution Amount by the Unit Price. Upon the occurrence
of a Nonredemption Event, the accrual rate for purposes of determining the PIK Distribution Amount shall increase, beginning on
the date that is ninety (90) days after the delivery by a Class C Unit Holder of a Notice of Redemption in respect of such
Nonredemption Event, and through the first Distribution Date thereafter, from a per annum rate of 5.0% to a per annum rate of 7.5%
compounding quarterly, and shall further increase as of the day immediately following each subsequent Distribution Date, beginning
on the date immediately after such first Distribution Date, by 1.25% per annum for the next four quarterly periods thereafter,
up to a maximum per annum rate of 12.5%, accruing on each Class C Unit set forth in such Notice of Redemption that remains
outstanding until a Full Redemption has occurred.

 

(h)            Section 16.5(a)(iii) of
the Partnership Agreement is hereby amended and restated in its entirety as follows:

 

If a Recapitalization Agreement is not executed
and delivered on or before the Distribution Date occurring on March 31, 2021, without derogating from the Company’s
obligation to pay the Class C Cash Distribution Amount on that Distribution Date (including, for the avoidance of doubt, in
respect of all of the Class C Units issued in respect of the 12/31/20 PIK Distribution Amount (including the 3/31/21 Redeemed
Units, prior to giving effect to the redemption required pursuant to this Section 16.5(a)(iii))), the Company shall also be
required, automatically and without any notice or other action required on the part of the Initial Preferred LP, on March 31,
2021, to redeem from the Initial Preferred LP a number of Class C Units equal to sixty percent (60%) of the 12/31/20 PIK Distribution
Amount (the “3/31/21 Redeemed Units”) for an amount per 3/31/21 Redeemed Unit in cash equal to the Liquidation
Preference of such 3/31/21 Redeemed Unit; provided, however that the Company shall not be required to redeem any
3/31/21 Redeemed Unit if (1) the Company has no Legally Available Funds (in which case the Company shall not be permitted
to withhold payments based upon a claim of no Legally Available Funds unless it shall have delivered to the Class C Unit Holders
a certificate signed by the Chief Executive Officer, the Chief Financial Officer or any other employee performing a similar function
for the Company or the General Partner setting forth such determination in reasonable detail as of the date of such claim) to pay
the full amount required to redeem such 3/31/21 Redeemed Units, or (2) no cash is available to make such payment after taking
into account the actual cost of PIPs and contractual reserves, in each case, to the extent specifically approved pursuant to Section 16.3
 ‎hereof and, with respect to both of clauses (1) and (2) immediately above without requiring the Company to incur
additional Debt, issue additional Securities or consummate asset sales. The limitations on the amount and number of Class C
Units that may be redeemed set forth in Section 16.5(a)(vi) shall not apply to any redemption pursuant to this Section 16.5(a)(iii).
The impact of any redemption pursuant to this Section 16.5(a)(iii) shall be the same as if such redemption were effected
pursuant to the delivery of a Notice of Redemption, and, on March 31, 2021: (A) the 3/31/21 Redeemed Units shall be delivered
to the Company in accordance with Section 16.5(b); (B) all Class C Cash Distribution Amounts on the 3/31/21 Redeemed
Units (but, for the avoidance of doubt, not with respect to any Class C Units remaining outstanding and held by the Initial
Preferred LP or any other Holder of Class C Units) will cease to accrue, the 3/31/21 Redeemed Units will be deemed to be no
longer outstanding and all of the rights of the Initial Preferred LP with respect to the 3/31/21 Redeemed Units (but, for the avoidance
of doubt, not with respect to any Class C Units remaining outstanding and held by the Initial Preferred LP or any other Holder
of Class C Units, in accordance with the terms of this Agreement) shall cease; and (C) the redemption price will be paid
to the Initial Preferred LP in accordance with this Section 16.5(a)(iii) and the 3/31/21 Redeemed Units will be promptly
cancelled by the Company after giving effect to the redemption of the 3/31/21 Redeemed Units.

 

    4

     

    

 

(i)             Section 16.5(a)(v) of
the Partnership Agreement is hereby amended and restated in its entirety as follows:

 

Such redemption payments shall be due and
owing as of the Redemption Date regardless of the availability of cash, including Available Cash, to pay such amounts. In the event
any redemption payment is not made when due because cash is not available therefor including by operation of legal prohibitions
imposed by operation of Section 17-607 of the Act, then the Class C Units shall continue to accrue Class C Cash
Distribution Amounts and PIK Distributions. Except with respect to a redemption pursuant to Sections 16.5(a)(iii), in which case
the Redemption Date shall be March 31, 2021, the Redemption Date shall be specified in a Notice of Redemption, and, (A) in
the case of any redemption request made pursuant to Sections 16.5(a)(i) and (ii), shall be not less than sixty (60) days after
the delivery of such Notice of Redemption, and (B) in the case of any redemption request made pursuant to Section 16.5(a)(iv),
shall be not less than one hundred fifty (150) days after the delivery of such Notice of Redemption.

 

2.             Miscellaneous.

 

(a)            The
parties acknowledge and agree that the execution and delivery of this Amendment by the Initial Preferred LP shall, to the extent
such approval is required pursuant to Section 16.3 of the Partnership Agreement, be deemed to be the approval by the affirmative
vote of the Holders of at least a majority of the Class C Units of this Amendment and all transactions contemplated hereby.

 

    5

     

    

 

(b)            This
Amendment may be executed (including by electronic transmission) with counterpart signature pages or in counterparts, all
of which together shall constitute one agreement binding on all of the parties hereto, notwithstanding that all such parties are
not signatories to the original or the same counterpart. Each party shall become bound by this Amendment immediately upon affixing
its signature hereto.

 

(c)            This
Amendment shall be construed and enforced in accordance with and governed by the laws of the State of Delaware, without regard
to the principles of conflicts of laws thereof.

 

(d)            If
any provision of this Amendment is or becomes invalid, illegal or unenforceable in any respect, the validity, legality and enforceability
of the remaining provisions contained herein shall not be affected thereby.

 

(e)            This
Amendment contains the entire understanding and agreement among the parties hereto with respect to the subject matter hereof and
supersedes any other prior written or oral understandings or agreements among them with respect thereto.

 

(f)             The
Partnership Agreement (as amended by this Amendment) shall continue to be in full force and effect and is hereby in all respects
ratified and confirmed.
