(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 (except if the
Company is not then eligible to register for resale the Registrable Securities on Form S-3, in which case such registration shall
be on another appropriate form in accordance herewith, subject to the provisions of Section 2(e)) 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. Subject to the terms of this Agreement, the Company shall use its reasonable best 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 reasonable best efforts to keep such Registration Statement continuously effective under the Securities Act until 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 Company shall immediately 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).


 




    	 	4	 



     


    

 


(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, subject to the provisions of Section 2(e); 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.


 


(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:


 


		a.	First, the Company shall reduce or eliminate any securities to be included by any Person other
than a Holder;



 


		b.	Second, the Company shall reduce Registrable Securities held by any person/entity who received
such Registrable Securities pursuant to the Diogenix Agreement



 


		c.	Third, the Company shall reduce Registrable Securities represented by Warrant Shares and Other
Warrant Shares (applied, in the case that some Warrant Shares and Other Warrant Shares may be registered, to the Holders on a pro
rata basis based on the total number of unregistered Warrant Shares and Other Warrant Shares held by such Holders); and



 


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



 



    	 	5	 



     


    

 


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 best 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.


 


(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) calendar 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 3.0% multiplied by
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.

(e)          If
Form S-3 is not available for the registration of the resale of Registrable Securities hereunder, the Company shall (i) register
the resale of the Registrable Securities on another appropriate form and (ii) undertake to register the Registrable Securities
on Form S-3 as soon as such form is available, provided that the Company shall maintain the effectiveness of the Registration
Statement then in effect until such time as a Registration Statement on Form S-3 covering the Registrable Securities has been declared
effective by the Commission.


 


		3.	Registration Procedures.



 


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


 


(a)          Not

to the filing of any related Prospectus or any amendment or supplement thereto (including 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. Notwithstanding the above, the Company shall not be obligated to provide the Holders
advance copies of any universal shelf registration statement registering securities in addition to those required hereunder, or
any Prospectus prepared thereto. 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 five (5) 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 B (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 fourth (4th) Trading Day following the date on which
such Holder receives draft materials in accordance with this Section.


 




    	 	7	 



     


    

 


(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.


 




    	 	8	 



     


    

 


(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, and (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,
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 reasonable best 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.


 


(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).


 




    	 	9	 



     


    

 


(h)          The
Company shall cooperate with any broker-dealer through which a Holder proposes to resell its Registrable Securities in effecting
a filing with the FINRA Corporate Financing Department pursuant to FINRA Rule 5110, as requested by any such Holder, and the Company
shall pay the filing fee required by such filing within two (2) Business Days of request therefor.


 


(i)           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.


 


(j)           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.


 


(k)          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 best 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(k) 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.

(l)           Comply
with all applicable rules and regulations of the Commission.


 


(m)         The
Company shall use its reasonable best efforts to maintain eligibility for use of Form S-3 (or any successor form thereto) for the
registration of the resale of Registrable Securities.


 


(n)          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.


 


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,

with respect to any filing that may be required to be made by any broker through which a Holder intends to make sales of Registrable
Securities with FINRA pursuant to FINRA Rule 5110, so long as the broker is receiving no more than a customary brokerage commission
in connection with such sale, (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

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

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
and actually used herein, 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, threat 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).


 




    	 	12	 



     


    

 


(b)          Indemnification
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 arising out of or based solely upon: (x) such Holder’s
failure to comply with any applicable prospectus delivery requirements of the Securities Act through no fault of the Company or
(y) 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 and such information was actually used therein or (ii)
to the extent, but only to the extent, that such information relates to 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
(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 any selling Holder under this Section 5(b) be greater in amount than the dollar amount of the net
proceeds received by such Holder upon the sale of the Registrable Securities giving rise to such indemnification obligation.


 




    	 	13	 



     


    

 


(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.


 


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.


 




    	 	14	 



     


    

 


(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. Notwithstanding the provisions of this Section 5(d), no Holder shall be required to contribute
pursuant to this Section 5(d), in the aggregate, any amount in excess of the amount by which the net proceeds actually received
by such Holder from the sale of the Registrable Securities subject to the Proceeding exceeds the amount of any damages that such
Holder has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission.


 


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 would 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 and no bond or
similar items shall be requested to be posted.


 






    	 	15	 



     


    

 


(b)          No
Piggyback on Registrations; Prohibition on Filing Other Registration Statements. Except for shares of Common Stock that were
(i) issued and/or (ii) are issuable upon exercise, conversion and/or exchange of securities exercisable, convertible and/or exchangeable
into shares of Common Stock pursuant to the Diogenix Agreement, 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 until all Registrable Securities are registered
pursuant to a Registration Statement that is declared effective by the Commission, provided that this Section 6(b) (i) shall not
prohibit the Company from filing amendments to registration statements filed prior to the date of this Agreement and (ii) shall
not prohibit the Company from filing a shelf registration statement on Form S-3 for a primary offering by the Company, provided
that the Company makes no offering of securities pursuant to such shelf registration statement prior to the effective date of the
Registration Statement required hereunder that includes all of the Registrable Securities.


 


(c)          Compliance.
Each Holder covenants and agrees that it will comply with the prospectus delivery requirements of the Securities Act as applicable
to it (unless an exemption therefrom is available) in connection with sales of Registrable Securities pursuant to a Registration
Statement.


 


(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 best 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).


 




    	 	16	 



     


    

 


(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.


 


(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 67% or more of the then outstanding Registrable Securities (for purposes of clarification, this
includes any Registrable Securities issuable upon exercise or conversion of any Security). 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.


 


(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 5.7 of the Purchase Agreement.


 




    	 	17	 



     


    

 


(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 governed
by and construed and enforced in accordance with the internal laws of the State of New York, without regard to the principles of
conflict of laws thereof.  Each party agrees that all legal proceedings concerning the interpretation, enforcement and defense
of the transactions contemplated by this Agreement (whether brought against a party hereto or its respective Affiliates, directors,
officers, shareholders, employees or agents) shall be commenced in the state and federal courts sitting in the City of New York,
Borough of Manhattan (the “New York Courts”).  Each party hereto hereby irrevocably submits to the exclusive
jurisdiction of the New York Courts for the adjudication of any dispute hereunder or in connection herewith or with any transaction
contemplated hereby or discussed herein (including but not limited to, with respect to the enforcement of this Agreement), and
hereby irrevocably waives, and agrees not to assert in any suit, action or proceeding, any claim that it is not personally subject
to the jurisdiction of such New York Courts, or such New York Courts are improper or inconvenient venue for such proceeding. 
Each party hereby irrevocably waives personal service of process and consents to process being served in any such suit, action
or proceeding by mailing a copy thereof via registered or certified mail or overnight delivery (with evidence of delivery) to such
party at the address in effect for notices to it under this Note and agrees that such service shall constitute good and sufficient
service of process and notice thereof.  Nothing contained herein shall be deemed to limit in any way any right to serve process
in any other manner permitted by applicable law. Each party hereto hereby irrevocably waives, to the fullest extent permitted by
applicable law, any and all right to trial by jury in any legal proceeding arising out of or relating to this Agreement or the
transactions contemplated hereby. If any party shall commence an action or proceeding to enforce any provisions of this Note, then
the prevailing party in such action or proceeding shall be reimbursed by the other party for its attorneys fees and other costs
and expenses incurred in the investigation, preparation and prosecution of such action or proceeding.


 




    	 	18	 



     


    

 


(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.


 


(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 asset 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.


 


(p)          Lock-up.
As a condition precedent to each Diogenix Person including their Registrable Securities in a Registration Statement, each such
Diogenix Person shall enter into a Lock-Up Agreement in the form substantially similar as annexed hereto as Exhibit A.

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 OTC Bulletin Board 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 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 brokers-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.


 


Because Selling Stockholders
may be deemed to be “underwriters” within the meaning of the Securities Act, they will be subject to the prospectus
delivery requirements of the Securities Act including Rule 172 thereunder. In addition, any securities covered by this prospectus
which qualify for sale pursuant to Rule 144 under the Securities Act may be sold under Rule 144 rather than under this prospectus.
The Selling Stockholders have advised us that there is no underwriter or coordinating broker acting in connection with the proposed
sale of the resale securities by the Selling Stockholders.


 


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 securities 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).
