without the consent of the Holders, withdraw such registration statement prior to its becoming effective if the Company or such
other stockholders have elected to abandon the proposal to register the securities proposed to be registered thereby. Notwithstanding
the foregoing, Piggyback Registration will not apply to any shares which can be sold without limitation under Rule 144.

    	5

    	 

    

(c)       Underwriting.
If a Piggyback Registration is for a registered public offering that is to be made by an underwriting, the Company shall so advise
the Holders of the Registrable Securities eligible for inclusion in such Registration Statement pursuant to Sections 3(b). In
that event, the right of any Holder to Piggyback Registration shall be conditioned upon such Holder’s participation in such
underwriting and the inclusion of such Holder’s Registrable Securities in the underwriting to the extent provided herein.
All Holders proposing to sell any of their Registrable Securities through such underwriting shall (together with the Company and
any other stockholders of the Company selling their securities through such underwriting) enter into an underwriting agreement
in customary form with the underwriter selected for such underwriting by the Company or the selling stockholders, as applicable.
Notwithstanding any other provision of this Section, if the underwriter or the Company determines that marketing factors require
a limitation on the number of shares of Common Stock or the amount of other securities to be underwritten, the underwriter may
exclude some or all Registrable Securities from such registration and underwriting. The Company shall so advise all Holders (except
those Holders who failed to timely elect to include their Registrable Securities through such underwriting or have indicated to
the Company their decision not to do so), and indicate to each such Holder the number of shares of Registrable Securities that
may be included in the registration and underwriting, if any. The number of shares of Registrable Securities to be included in
such registration and underwriting shall be allocated among such Holders as follows:

(i)If
the Piggyback Registration was initiated by the Company, the number of shares that may be included in the registration and underwriting
shall be allocated first to the Company and then, subject to obligations and commitments existing as of the date hereof, to all
selling stockholders, including the Holders, who have requested to sell in the registration on a pro rata basis according to the
number of shares requested to be included therein; and

(ii)If
the Piggyback Registration was initiated by the exercise of demand registration rights by a stockholder or stockholders of the
Company (other than the Holders), then the number of shares that may be included in the registration and underwriting shall be
allocated first to such selling stockholders who exercised such demand and then, subject to obligations and commitments existing
as of the date hereof, to all other selling stockholders, including the Holders, who have requested to sell in the registration
on a pro rata basis according to the number of shares requested to be included therein.

No
Registrable Securities excluded from the underwriting by reason of the underwriter’s marketing limitation shall be included
in such registration. If any Holder disapproves of the terms of any such underwriting, such Holder may elect to withdraw such
Holder’s Registrable Securities therefrom by delivering a written notice to the Company and the underwriter. The Registrable
Securities so withdrawn from such underwriting shall also be withdrawn from such registration; provided, however, that, if by
the withdrawal of such Registrable Securities, a greater number of Registrable Securities held by other Holders may be included
in such registration (up to the maximum of any limitation imposed by the underwriters), then the Company shall offer to all Holders
who have included Registrable Securities in the registration the right to include additional Registrable Securities pursuant to
the terms and limitations set forth herein in the same proportion used above in determining the underwriter limitation.

    	6

    	 

    

(d)        Occurrence
of Registration Event. If a Registration Event occurs, then the Company will make payments to each Holder of Registrable Securities
(a “Qualified Purchaser”), as liquidated damages for the amount of damages to the Qualified Purchaser by reason thereof,
at a rate equal to one percent (1.00%) of the purchase price per share paid by such Qualified Purchaser for the Registrable Securities
(including, without limitation, Bridge Note conversion amounts) for the Registrable Securities then held by each Qualified Purchaser
for each full period of 30 days of the Registration Default Period (which shall be pro rated for any period less than 30 days);
provided, however, if a Registration Event occurs (or is continuing) on a date more than one-year after the Company filed a Current
Report on Form 8-K relating to the Merger and the PPO and providing Form 10 information with respect thereto, liquidated damages
shall be paid only with respect to that portion of the Qualified Purchaser’s Registrable Securities that cannot then be
immediately resold in reliance on Rule 144. Notwithstanding the foregoing, the maximum amount of liquidated damages that may be
paid to any Qualified Purchaser pursuant to this Section 3(d) shall be an amount equal to ten percent (10%) of the purchase price
per share paid by such Qualified Purchaser for the Registrable Securities held by such Qualified Purchaser at the time of the
first occurrence of a Registration Event. Each such payment shall be due and payable within five days after the end of each full
30-day period of the Registration Default Period until the termination of the Registration Default Period and within five days
after such termination. Such payments shall constitute the Qualified Purchaser’s exclusive remedy for such events. If the
Company fails to pay any partial liquidated damages or refund pursuant to this Section in full within seven days after the date
payable, the Company will pay interest thereon at a rate of 8% 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 Registration Default Period shall terminate upon (i) the filing of the Registration
Statement in the case of clause (a) of the definition of Registration Event, (ii) the SEC Effective Date in the case of clause
(b) of the definition of Registration Event, (iii) the ability of the Qualified Purchaser to effect sales pursuant to the Registration
Statement in the case of clause (c) of the definition of Registration Event, (iv) the listing or inclusion and/or trading of the
Common Stock on an Approved Market, as the case may be, in the case of clause (d) of the definition of Registration Event, and
(v) in the case of the events described in clauses (b) and (c) of the definition of Registration Event, the earlier termination
of the Registration Default Period. The amounts payable as liquidated damages pursuant to this Section 3(d) shall be payable in
lawful money of the United States.

    	7

    	 

    

(e)         Notwithstanding
the provisions of Section 3(d) above, (a) if the Commission does not declare the Registration Statement effective on or before
the Registration Default Date, or (b) if the Commission allows the Registration Statement to be declared effective at any time
before or after the Registration Default Date, subject to the withdrawal of certain Registrable Securities from the Registration
Statement, and the reason for (a) or (b) is the Commission’s determination that (x) the offering of any of the Registrable
Securities constitutes a primary offering of securities by the Company, (y) Rule 415 may not be relied upon for the registration
of the resale of any or all of the Registrable Securities, and/or (z) a Holder of any Registrable Securities must be named as
an underwriter, the Holders understand and agree that in the case of (b) the Company may reduce, on a pro rata basis, the total
number of Registrable Securities to be registered on behalf of each such Holder, and in the case of (a) or (b), a Holder shall
not be entitled to any liquidated damages with respect to the Registrable Securities not registered for the reason set forth in
(a), or so reduced on a pro rata basis as set forth in (b). In any such pro rata reduction, the number of Registrable Securities
to be registered on such Registration Statement will first be reduced by the Registrable Securities represented by the Registrable
Warrant Shares (applied, in the case that some Registrable Warrant Shares may be registered, to the Holders on a pro rata basis
based on the total number of unregistered Registrable Warrant Shares held by such Holders on a fully diluted basis), and second
by the Registrable Securities represented by the Registrable Shares (applied, in the case that some Registrable Shares may be
registered, to the Holders on a pro rata basis based on the total number of unregistered Registrable Shares held by such Holders).
In addition, any such affected Holder shall be entitled to Piggyback Registration rights after the Registration Statement is declared
effective by the Commission until the earlier of such time as: (AA) all Registrable Securities have been registered pursuant to
an effective Registration Statement, (BB) the Registrable Securities may be resold without restriction pursuant to Rule 144 of
the Securities Act, or (CC) the Holder agrees to be named as an underwriter in any such registration statement. The Holders acknowledge
and agree the provisions of this paragraph may apply to the Registration Statement and Piggyback Registrations.

4.Registration
Procedures for Registrable Securities.  The Company will keep each Holder reasonably advised as to the filing and
effectiveness of the Registration Statement. At its expense with respect to the Registration Statement, the Company will:

(a)        prepare
and file with the Commission with respect to the Registrable Securities, a Registration Statement on Form S-1, or any other form
for which the Company then qualifies or which counsel for the Company shall deem appropriate and which form shall be available
for the sale of the Registrable Securities in accordance with the intended methods of distribution thereof, and use its commercially
reasonable efforts to cause such Registration Statement to become effective and shall remain effective for a period of two years
or for such shorter period ending on the earlier to occur of (i) the date as of which all of the Holders as selling stockholders
thereunder may sell all of the Registrable Securities registered for resale thereon without restriction pursuant to Rule 144 (or
any successor rule thereto) promulgated under the Securities Act or (ii) the date when all of the Registrable Securities registered
thereunder shall have been sold (the “Effectiveness Period”); thereafter, the Company shall be entitled to withdraw
such Registration Statement and the Holders shall have no further right to offer or sell any of the Registrable Securities registered
for resale thereon pursuant to the respective Registration Statement (or any prospectus relating thereto);

the Registration Statement is subject to review by the Commission, promptly respond to all comments and diligently pursue resolution

the Securities Act) as such Holders may reasonably request, in conformity with the requirements of the Securities Act, to the
extent required in order for the Holder to meet any prospectus delivery requirement applicable to the disposition of the Registrable
Securities owned by such Holder, but only during the Effectiveness Period;

(e)     use
its commercially reasonable efforts to register or qualify such registration under such other applicable securities laws of such
jurisdictions in the United States as any Holder of Registrable Securities covered by such Registration Statement reasonably requests
and as may be necessary for the marketability of the Registrable Securities (such request to be made by the time the applicable
Registration Statement is deemed effective by the Commission) and do any and all other acts and things necessary to enable such
Holder to consummate the disposition in such jurisdictions of the Registrable Securities owned by such Holder; provided, that
the Company shall not be required to (i) qualify generally to do business in any jurisdiction where it would not otherwise be
required to qualify but for this paragraph, (ii) subject itself to taxation in any such jurisdiction, or (iii) consent to general
service of process in any such jurisdiction.

(f)      notify
each Holder of Registrable Securities, the disposition of which requires delivery of a prospectus relating thereto under the Securities
Act, of the happening of any event (as promptly as practicable after becoming aware of such event), which comes to the Company’s
attention, that will after the occurrence of such event cause the prospectus included in such Registration Statement, if not amended
or supplemented, to contain an untrue statement of a material fact or an omission to state a material fact required to be stated
therein or necessary to make the statements therein not misleading and the Company shall promptly thereafter prepare and furnish
to such Holder a supplement or amendment to such prospectus (or prepare and file appropriate reports under the Exchange Act) so
that, as thereafter delivered to the purchasers of such Registrable Securities, such prospectus shall not contain an 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
not misleading, unless suspension of the use of such prospectus otherwise is authorized herein or in the event of a Blackout Period,
in which case no supplement or amendment need be furnished (or Exchange Act filing made) until the termination of such suspension
or Blackout Period;

and continue to comply during the Effectiveness Period, in all material respects with the Securities Act and the Exchange Act
and with all applicable rules and regulations of the Commission with respect to the disposition of all securities covered by such

the Company are then listed or traded;

a transfer agent and registrar, which may be a single entity, for the shares of Common Stock at all times;

(k)     If
requested by the Holders, cooperate with the Holders to facilitate the timely preparation and delivery of certificates representing

denominations and registered in such names as any such Holders may request;

(l)      during
the Effectiveness Period, refrain from bidding for or purchasing any Common Stock or any right to purchase Common Stock or attempting
to induce any person to purchase any such security or right if such bid, purchase or attempt would in any way limit the right
of the Holders to sell Registrable Securities by reason of the limitations set forth in Regulation M of the Exchange Act; and

(m)     take
all other reasonable actions necessary to expedite and facilitate the disposition by the Holders of the Registrable Securities
pursuant to the Registration Statement.

event of the kind described in Section 4(f) hereof or of the commencement of a Blackout Period, such Holder shall discontinue
the disposition of Registrable Securities included in the Registration Statement until such Holder’s receipt of the copies
of the supplemented or amended prospectus contemplated by Section 4(f) hereof or notice of the end of the Blackout Period, and,

covering such Registrable Securities current at the time of receipt of such notice.

without limitation, all registration, filing, stock exchange fees, printing expenses, all fees and expenses of complying with
applicable securities laws, and the fees and disbursements of counsel for the Company and of its independent accountants; provided,
that, in any registration, each party shall pay for its own underwriting discounts and commissions and transfer taxes. Except
as provided in this Section and Section 9, the Company shall not be responsible for the expenses of any attorney or other advisor
employed by a Holder.

7.          Assignment

of the Company; provided, however, that any Holder may assign its rights under this Agreement without such consent to a Permitted
Assignee as long as (a) such transfer or assignment is effected in accordance with applicable securities laws; (b) such transferee
or assignee agrees in writing to become subject to the terms of this Agreement; and (c) such Holder notifies the Company in writing

claims, damages or liabilities, joint or several, and expenses to which the Holder or any such director, officer, partner or underwriter
or controlling person may become subject under the Securities Act, the Exchange Act, or any other federal or state law, insofar
as such losses, claims, damages, liabilities or expenses (or actions or proceedings, whether commenced or threatened, in respect

in connection with this Agreement; and the Company shall reimburse the Holder, and each such director, officer, partner, underwriter
and controlling person for any legal or any other expenses reasonably incurred by them in connection with investigating, defending
or settling any such loss, claim, damage, liability, action or proceeding; provided, that such indemnity agreement found in this
Section 9(a) shall in no event exceed the net proceeds from the PPO (which includes the proceeds from the sale of the Bridge Notes),
as applicable, received by the Company; and provided further, that the Company shall not be liable in any such case (i) to the
extent that any such loss, claim, damage, liability (or action or proceeding in respect thereof) or expense arises out of or is
based upon (a) an untrue statement in or omission from such registration statement, any such preliminary prospectus, final prospectus,
summary prospectus, amendment or supplement in reliance upon and in conformity with written information furnished to the Company
by the Holder specifically for use in the preparation thereof or (b) any failure of a Holder to distribute Registrable Securities
in accordance with applicable laws, or (ii) if the person asserting any such loss, claim, damage, liability (or action or proceeding
in respect thereof) who purchased the Registrable Securities that are the subject thereof did not receive a copy of an amended
preliminary prospectus or the final prospectus (or the final prospectus as amended or supplemented) at or prior to the written
confirmation of the sale of such Registrable Securities to such person because of the failure of such Holder or underwriter to
so provide such amended preliminary or final prospectus and the untrue statement or omission of a material fact made in such preliminary
prospectus was corrected in the amended preliminary or final prospectus (or the final prospectus as amended or supplemented).
Such indemnity shall remain in full force and effect regardless of any investigation made by or on behalf of the Holders, or any
such director, officer, partner, underwriter or controlling person and shall survive the transfer of such shares by the Holder.

    	11

    	 

    

(b)        As
a condition to including Registrable Securities in any registration statement filed pursuant to this Agreement, each Holder agrees
to be bound by the terms of this Section 9 and to indemnify and hold harmless, to the fullest extent permitted by law, the Company,
its directors and officers, and each other person, if any, who controls the Company within the meaning of Section 15 of the Securities
Act, against any losses, claims, damages or liabilities, joint or several, to which the Company or any such director or officer
or controlling person may become subject under the Securities Act, the Exchange Act, or any other federal or state law, to the
extent arising out of or based upon: (x) such Holder’s failure to comply with the prospectus delivery requirements of the
Securities Act, (y) any failure of a Holder to distribute Registrable Securities in accordance with applicable laws, or (z) any
untrue or alleged untrue statement of a material fact contained in any 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 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 specifically for inclusion in the registration statement or such prospectus or (ii) to
the extent that (1) such untrue statements or omissions are based 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 the Registration Statement, such prospectus or such form of prospectus or in any amendment or
supplement thereto or (2) in the case of an occurrence of an event of the type specified in Section 4(f) hereof, the use by such
Holder of an outdated or defective prospectus after the Company has notified such Holder in writing that the prospectus is outdated
or defective and prior to the receipt by such Holder of the advice contemplated in Section 4(f). In no event shall the liability
of any selling Holder hereunder 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.   

  

    	12

    	 

    
     

(c)          Promptly
after receipt by an indemnified party of notice of the commencement of any action or proceeding involving a claim referred to
in this Section (including any governmental action), such indemnified party shall, if a claim in respect thereof is to be made
against an indemnifying party, give written notice to the indemnifying party of the commencement of such action; provided, that
the failure of any indemnified party to give notice as provided herein shall not relieve the indemnifying party of its obligations
under this Section, except to the extent that the indemnifying party is actually prejudiced by such failure to give notice. In
case any such action is brought against an indemnified party, unless in the reasonable judgment of counsel to such indemnified
party a conflict of interest between such indemnified and indemnifying parties may exist or the indemnified party may have defenses
not available to the indemnifying party in respect of such claim, the indemnifying party shall be entitled to participate in and
to assume the defense thereof, with counsel reasonably satisfactory to such indemnified party and, after notice from the indemnifying
party to such indemnified party of its election so to assume the defense thereof, the indemnifying party shall not be liable to
such indemnified party for any legal or other expenses subsequently incurred by the latter in connection with the defense thereof,
unless in such indemnified party’s reasonable judgment a conflict of interest between such indemnified and indemnifying
parties arises in respect of such claim after the assumption of the defenses thereof or the indemnifying party fails to defend
such claim in a diligent manner, other than reasonable costs of investigation. Neither an indemnified nor an indemnifying party
shall be liable for any settlement of any action or proceeding effected without its consent. No indemnifying party shall, without
the consent of the indemnified party, consent to entry of any judgment or enter into any settlement, which does not include as
an unconditional term thereof the giving by the claimant or plaintiff to such indemnified party of a release from all liability
in respect of such claim or litigation. Notwithstanding anything to the contrary set forth herein, and without limiting any of
the rights set forth above, in any event any party shall have the right to retain, at its own expense, counsel with respect to
the defense of a claim.

(d)If
an indemnifying party does or is not permitted to assume the defense of an action pursuant to Sections 9(c) or in the case of
the expense reimbursement obligation set forth in Sections 9(a) and (b), the indemnification required by Sections 9(a) and 9(b)
shall be made by periodic payments of the amount thereof during the course of the investigation or defense, as and when bills
received or expenses, losses, damages, or liabilities are incurred.

(e)           If
the indemnification provided for in Section 9(a) or 9(b) is held by a court of competent jurisdiction to be unavailable to an
indemnified party with respect to any loss, liability, claim, damage or expense referred to herein, the indemnifying party, in
lieu of indemnifying such indemnified party hereunder, shall (i) contribute to the amount paid or payable by such indemnified
party as a result of such loss, liability, claim, damage or expense as is appropriate to reflect the proportionate relative fault
of the indemnifying party on the one hand and the indemnified party on the other (determined by reference to, among other things,
whether the untrue or alleged untrue statement of a material fact or omission relates to information supplied by the indemnifying
party or the indemnified party and the parties’ relative intent, knowledge, access to information and opportunity to correct
or prevent such untrue statement or omission), or (ii) if the allocation provided by clause (i) above is not permitted by applicable
law or provides a lesser sum to the indemnified party than the amount hereinafter calculated, not only the proportionate relative
fault of the indemnifying party and the indemnified party, but also the relative benefits received by the indemnifying party on
the one hand and the indemnified party on the other, as well as any other relevant equitable considerations. No indemnified party
guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution
from any indemnifying party who was not guilty of such fraudulent misrepresentation.

(f)          Other
Indemnification. Indemnification similar to that specified in this Section (with appropriate modifications) shall be given
by the Company and each Holder of Registrable Securities with respect to any required registration or other qualification of securities
under any federal or state law or regulation or governmental authority other than the Securities Act.

    	13

    	 

    

10.          Rule
144.  With a view to making available to the Holders the benefits of Rule 144 and any other rule or regulation of
the Commission that may at any time permit the Holders to sell the Registrable Securities to the public without registration,
the Company agrees: (i) to make and keep public information available as those terms are understood in Rule 144, (ii) to file
with the Commission in a timely manner all reports and other documents required to be filed by an issuer of securities registered
under the Securities Act or the Exchange Act pursuant to Rule 144, (iii) as long as any Holder owns any Registrable Securities,
to furnish in writing upon such Holder’s request a written statement by the Company that it has complied with the reporting
requirements of Rule 144 and of the Securities Act and the Exchange Act, and to furnish to such Holder a copy of the most recent
annual or quarterly report of the Company, and such other reports and documents so filed by the Company as may be reasonably requested
in availing such Holder of any rule or regulation of the Commission permitting the selling of any such Registrable Securities
without registration and (iv) undertake any additional actions commercially reasonably necessary to maintain the availability
of the use of Rule 144.

11.         Corporate
Existence.  For a period of one (1) year commencing on the date hereof, and so long as any Holder owns any Registrable
Securities, the Company shall not directly or indirectly consummate any merger, reorganization, restructuring, reverse stock split,
consolidation, sale of all or substantially all of the Company’s assets or any similar transaction or related transactions
(each such transaction, an “Organizational Change”), unless, prior to the consummation of an Organizational Change,
the Company obtains the written consent of the Majority Holders.

12.          Independent
Nature of Each Purchaser’s Obligations and Rights.  The obligations of each Purchaser under this Agreement
are several and not joint with the obligations of any other Purchaser, and each Purchaser shall not be responsible in any way
for the performance of the obligations of any other Purchaser under this Agreement. Nothing contained herein and no action taken
by any Purchaser pursuant hereto, shall be deemed to constitute such Purchasers as a partnership, an association, a joint venture,
or any other kind of entity, or create a presumption that the Purchasers are in any way acting in concert or as a group with respect
to such obligations or the transactions contemplated by this Agreement. Each Purchaser shall be entitled to independently protect
and enforce its rights, including without limitation the rights arising out of this Agreement, and it shall not be necessary for
any other Purchaser to be joined as an additional party in any proceeding for such purpose; provided, however, that the Majority
Holders shall be able to alter the rights of each Purchaser as provided herein.

13.          Other
Registration Rights.  After the date of this Agreement, the Company shall not, without the prior written consent
of the Majority Holders, enter into any agreement with any holder or prospective holder of any securities of the Company that
would require the Company to file a registration statement for such holder or prospective holder prior to the SEC Effective Date.

14.          Miscellaneous.

(a)Governing
Law. This Agreement shall be governed by and construed in accordance with the laws of the United States of America and the
State of New York, both substantive and remedial, without regard to New York conflicts of law principles. Any judicial proceeding
brought against either of the parties to this Agreement or any dispute arising out of this Agreement or any matter related hereto
shall be brought in the courts of the State of New York, New York County, or in the United States District Court for the Southern
District of New York and, by its execution and delivery of this Agreement, each party to this Agreement accepts the jurisdiction
of such courts. The foregoing consent to jurisdiction shall not be deemed to confer rights on any person other than the parties
to this Agreement.

    	14

    	 

    

(b)     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. The Company and each
Holder agree 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. Notwithstanding
the foregoing, the sole and exclusive remedy for a Registration Event shall be as set forth in Section 3(d).

(c)      Successors
and Assigns. Except as otherwise provided herein, the provisions hereof shall inure to the benefit of, and be binding upon,
the successors, Permitted Assignees, executors and administrators of the parties hereto.

(d)      No
Inconsistent Agreements. The Company has not entered, as of the date hereof, and shall not enter, on or after the date of
this Agreement, 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.

(e)       Entire
Agreement. This Agreement constitutes the full and entire understanding and agreement between the parties with regard to the
subjects hereof.

(f)       Notices,
etc. All notices or other communications which are required or permitted under this Agreement shall be in writing and sufficient
if delivered by hand, by facsimile transmission, by registered or certified mail, postage pre-paid, by electronic mail, or by
courier or overnight carrier, to the persons at the addresses set forth below (or at such other address as may be provided hereunder),
and shall be deemed to have been delivered as of the earlier of the date of actual delivery or, as of the first business day following
the date of transmission, if delivered by facsimile, five days after mailing, if delivered by registered or certified mail, or
the next business day if delivered by electronic mail or by overnight courier:

to be a waiver of any such breach or default, or an acquiescence therein, or of any similar breach or default thereunder occurring;
nor shall any waiver of any single breach or default be deemed a waiver of any other breach or default theretofore or thereafter
occurring. Any waiver, permit, consent or approval of any kind or character on the part of any Holder of any breach or default

provisions of this Agreement may be amended at any time and from time to time, and particular provisions of this Agreement may

    of the undersigned) has held any position or office or has had any other material relationship with the Company (or its predecessors

	 	State any exceptions here:

 

	 	 
	 	

	 	 

	1	Beneficially Owned:  A “beneficial
    owner” of a security includes any person who, directly or indirectly, through any contract, arrangement, understanding,
    relationship or otherwise has or shares (i) voting power, including the power to direct the voting of such security,
    or (ii) investment power, including the power to dispose of, or direct the disposition of, such security.  In addition,
    a person is deemed to have “beneficial ownership” of a security of which such person has the right to acquire
    beneficial ownership at any time within 60 days, including, but not limited to, any right to acquire such security: (i) through
    the exercise of any option, warrant or right, (ii) through the conversion of any security or (iii) pursuant to the
    power to revoke, or the automatic termination of, a trust, discretionary account or similar arrangement.
	 	 
	 	It is possible that a security may have more than one “beneficial owner,” such as a trust, with two co-trustees sharing voting power, and the settlor or another third party having investment power, in which case each of the three would be the “beneficial owner” of the securities in the trust.  The power to vote or direct the voting, or to invest or dispose of, or direct the investment or disposition of, a security may be indirect and arise from legal, economic, contractual or other rights, and the determination of beneficial ownership depends upon who ultimately possesses or shares the power to direct the voting or the disposition of the security.
	 	 
	 	The final determination of the existence of beneficial ownership depends upon the facts of each case.  You may, if you believe the facts warrant it, disclaim beneficial ownership of securities that might otherwise be considered “beneficially owned” by you.

 

	2	Affiliate: 
    An “affiliate” is a company or person that directly, or indirectly through one or more intermediaries, controls
    you, or is controlled by you, or is under common control with you.

    	 

    	 

    

The
undersigned agrees to promptly notify the Company of any inaccuracies or changes in the information provided herein that may occur
subsequent to the date hereof at any time while the Registration Statement remains effective.

By
signing below, the undersigned consents to the disclosure of the information contained herein in its answers to Items 1 through
5 and the inclusion of such information in the Registration Statement and the related prospectus and any amendments or supplements
thereto. The undersigned understands that such information will be relied upon by the Company in connection with the preparation
or amendment of the Registration Statement and the related prospectus and any amendments or supplements thereto.

ESCROW AGREEMENT

This
Escrow Agreement (this “Agreement”) is entered into as of January 17, 2012 by and between Dynastar Holdings, Inc.,
formerly known as Medical Design Studios, Inc., a Nevada corporation (the “Parent”), John S. Henderson IV (the “Indemnification
Representative”) and Gottbetter & Partners, LLP (the “Escrow Agent”).

WHEREAS,
the Parent has entered into an Agreement and Plan of Merger and Reorganization (the “Merger Agreement”) with Dynastar
Ventures, Inc., a Delaware corporation (the “Company”), (i) pursuant to which a wholly-owned subsidiary of the Parent
will merge with and into the Company, with the Company surviving the merger, (ii) the Company will become a wholly-owned subsidiary
of the Parent, and (iii) the stockholders of the Company (the “Company Stockholders”) will receive shares of common
stock of the Parent (the “Merger Shares”);

WHEREAS,
the Merger Agreement provides that 95% of the Merger Shares (the “Initial Shares”) to be issued to such Company
Stockholders shall be delivered to such Company Stockholders and 5% of the Merger Shares (the “Escrow Shares”) to
be issued to such Company Stockholders shall be delivered to the Escrow Agent to secure the indemnification obligations of the
Company Stockholders as of the Closing Date, as such term is defined in the Merger Agreement (collectively, the “Indemnifying
Stockholders”), to the Parent; and

WHEREAS,
the Merger Agreement provides for the execution of this Agreement and the establishment of an escrow account and the parties
hereto desire to establish the terms and conditions pursuant to which such escrow account will be established and maintained.

NOW,
THEREFORE, the parties hereto hereby agree as follows:

1.         
Escrow and Indemnification.

(a)         Escrow
of Shares. Simultaneously with the execution of this Agreement, the Parent shall cause to be issued and shall deposit with
the Escrow Agent certificates representing an aggregate number of shares of common stock of the Parent, as determined pursuant
to Section 1.8(b) of the Merger Agreement, issued in the name of the Escrow Agent. The shares deposited with the Escrow Agent
pursuant to this Section 1(a) are referred to herein as the “Escrow Shares.” The Escrow Shares shall be held as a
trust fund and shall not be subject to any lien, attachment, trustee process or any other judicial process of any creditor of
any party hereto. The Escrow Agent agrees to hold the Escrow Shares in an escrow account (the “Escrow Account”), subject
to the terms and conditions of this Agreement.

(b)         Indemnification.
The Indemnifying Stockholders have agreed in Section 6.1 of the Merger Agreement to indemnify and hold harmless the Parent from
and against certain Damages (as defined in Section 6.1 of the Merger Agreement). The Escrow Shares shall be (i) security for such
indemnity obligation of the Indemnifying Stockholders, subject to the limitations, and in the manner provided, in this Agreement
and the Merger Agreement and (ii) shall be the exclusive means for the Parent to collect any Damages with respect to which the
Parent is entitled to indemnification under Article VI of the Merger Agreement.

    	 

    	 

    

(c)         Dividends,
Etc. Any securities distributed in respect of or in exchange for any of the Escrow Shares, whether by way of stock dividends,
stock splits or otherwise, shall be issued in the name of the Escrow Agent or its nominee and shall be delivered to the Escrow
Agent, who shall hold such securities in the Escrow Account. Such securities shall be considered Escrow Shares for purposes hereof.
Any cash dividends or property (other than securities) distributed in respect of the Escrow Shares shall promptly be distributed
by the Escrow Agent to the Indemnifying Stockholders in accordance with Section 3(c) hereof.

(d)         Voting
of Shares. The Indemnification Representative shall have the right, in his sole discretion, on behalf of the Indemnifying
Stockholders, to direct the Escrow Agent in writing as to the exercise of any voting rights pertaining to the Escrow Shares, and
the Escrow Agent shall comply with any such written instructions. In the absence of such instructions, the Escrow Agent shall
not vote any of the Escrow Shares. The Indemnification Representative shall have no obligation to solicit consents or proxies
from the Indemnifying Stockholders for purposes of any such vote.

(e)         Transferability.
The respective interests of the Indemnifying Stockholders in the Escrow Shares shall not be assignable or transferable, other
than by operation of law. Notice of any such assignment or transfer by operation of law shall be given to the Escrow Agent and
the Parent, and no such assignment or transfer shall be valid until such notice is given.

2.
         Intentionally Omitted.

3.
         Distribution of Escrow Shares.

(a)         The
Escrow Agent shall distribute the Escrow Shares only in accordance with (i) a written instrument delivered to the Escrow Agent
that is executed by both the Parent and the Indemnification Representative and that instructs the Escrow Agent as to the distribution
of some or all of the Escrow Shares, (ii) an order of a court of competent jurisdiction, a copy of which is delivered to the Escrow
Agent by either the Parent or the Indemnification Representative, that instructs the Escrow Agent as to the distribution of some
or all of the Escrow Shares, or (iii) the provisions of Section 3(b) hereof.

(b)         Within
five business days after January 17, 2014 (the “Termination Date”), the Escrow Agent shall distribute to the Indemnifying
Stockholders all of the Escrow Shares then held in escrow, registered in the names of the Indemnifying Stockholders. Notwithstanding
the foregoing, if the Parent has previously delivered to the Escrow Agent a copy of a Claim Notice (as hereinafter defined) and
the Escrow Agent has not received written notice of the resolution of the claim covered thereby, or if the Parent has previously
delivered to the Escrow Agent a copy of an Expected Claim Notice (as hereinafter defined) and the Escrow Agent has not received
written notice of the resolution of the anticipated claim covered thereby, the Escrow Agent shall retain in escrow after the Termination
Date such number of Escrow Shares as have a Value (as defined in Section 4 below) equal to the Claimed Amount (as hereinafter
defined) covered by such Claim Notice or equal to the estimated amount of Damages set forth in such Expected Claim Notice, as
the case may be. Any Escrow Shares so retained in escrow shall be distributed only in accordance with the terms of clauses (i)
or (ii) of Section 3(a) hereof. For purposes of this Agreement, a Claim Notice means a written notification under the Merger Agreement
given by the Parent to the Indemnifying Stockholders which contains (i) a description and the amount (the “Claimed Amount”)
of any Damages incurred or reasonably expected to be incurred by the Parent, (ii) a statement that the Parent is entitled to indemnification
under Article 6 of the Merger Agreement for such Damages and a reasonable explanation of the basis therefor, and (iii) a demand
for payment (in the manner provided in Section 6.3 of the Merger Agreement) in the amount of such Damages. For purposes of this
Agreement, an Expected Claim Notice means a notice delivered pursuant to the Merger Agreement by the Parent to an Indemnifying
Stockholder, before expiration of a representation or warranty, to the effect that, as a result a legal proceeding instituted
by or written claim made by a third party, the Parent reasonably expects to incur Damages as a result of a breach of such representation
or warranty.

(c)         Any
distribution of all or a portion of the Escrow Shares (or cash or other property pursuant to Section 2(c)) to the Indemnifying
Stockholders shall be made by delivery of stock certificates issued in the name of the Indemnifying Stockholders (or cash or other
property), covering such percentage of the Escrow Shares (or cash or other property) being distributed as is calculated in accordance
with the percentages set forth opposite each such Indemnifying Stockholder’s name on Attachment A attached hereto (which
Attachment shall be updated after the date hereof if the Parent deposits additional Escrow Shares in the Escrow Account on behalf
of additional Company Stockholders after the Closing Date). Distributions to the Indemnifying Stockholders shall be made by mailing
stock certificates to such holders at their respective addresses shown on Attachment A (or such other address as may be provided
in writing to the Escrow Agent by any such Indemnifying Stockholder). No fractional Escrow Shares shall be distributed to Indemnifying
Stockholders pursuant to this Agreement. Instead, the number of shares that each Indemnifying Stockholder shall receive shall
be rounded up or down to the nearest whole number (provided that the Indemnification Representative shall have the authority to
effect such rounding in such a manner that the total number of whole Escrow Shares to be distributed equals the number of Escrow
Shares then held in the Escrow Account).

4.
         Valuation of Escrow Shares. For purposes of this Agreement, the “Value”
of any Escrow Shares shall be $0.20 per share, multiplied by the number of such Escrow Shares.

5.
         Fees and Expenses of Escrow Agent. The Parent shall pay the fees
of the Escrow Agent for the services to be rendered by the Escrow Agent hereunder.

6.
         Limitation of Escrow Agent’s Liability.

(a)         The
Escrow Agent shall incur no liability with respect to any action taken or suffered by it in reliance upon any notice, direction,
instruction, consent, statement or other documents believed by it to be genuine and duly authorized, nor for other action or inaction
except its own willful misconduct or gross negligence. The Escrow Agent shall not be responsible for the validity or sufficiency
of this Agreement. In all questions arising under the Escrow Agreement, the Escrow Agent may rely on the advice of counsel, and
the Escrow Agent shall not be liable to anyone for anything done, omitted or suffered in good faith by the Escrow Agent based
on such advice. The Escrow Agent shall not be required to take any action hereunder involving any expense unless the payment of
such expense is made or provided for in a manner reasonably satisfactory to it. In no event shall the Escrow Agent be liable for
indirect, punitive, special or consequential damages.

(b)         The
Parent and the Indemnifying Stockholders agree to indemnify the Escrow Agent for, and hold it harmless against, any loss, liability
or expense incurred without gross negligence or willful misconduct on the part of Escrow Agent, arising out of or in connection
with its carrying out of its duties hereunder. The Parent, on the one hand, and the Indemnifying Stockholders, on the other hand,
shall each be liable for one-half of such amounts.

7.
         Liability and Authority of Indemnification Representative; Successors and
Assignees.

(a)         The
Indemnification Representative shall not incur any liability to the Indemnifying Stockholders with respect to any action taken
or suffered by him in reliance upon any note, direction, instruction, consent, statement or other documents believed by him to
be genuinely and duly authorized, nor for other action or inaction except his own willful misconduct or gross negligence. The
Indemnification Representative may, in all questions arising under the Escrow Agreement, rely on the advice of counsel and the
Indemnification Representative shall not be liable to the Indemnifying Stockholders for anything done, omitted or suffered in
good faith by the Indemnification Representative based on such advice.

(b)         In
the event of the death or permanent disability of the Indemnification Representative, or his or her resignation or termination
as an Indemnification Representative, a successor Indemnification Representative shall be elected by a majority vote of the Indemnifying
Stockholders, with each such Indemnifying Stockholder (or his, her or its successors or assigns) to be given a vote equal to the
number of votes represented by the shares of stock of the Company held by such Indemnifying Stockholder immediately prior to the
effective time of the Merger Agreement. Each successor Indemnification Representative shall have all of the power, authority,
rights and privileges conferred by this Agreement upon the original Indemnification Representative, and the term “Indemnification
Representative” as used herein shall be deemed to include each successor Indemnification Representative.

(c)         The
Indemnification Representative shall have full power and authority to represent the Indemnifying Stockholders, and their successors,
with respect to all matters arising under this Agreement and Article 6 of the Merger Agreement and all actions taken by the Indemnification
Representative hereunder or under Article 6 of the Merger Agreement shall be binding upon the Indemnifying Stockholders, and their
successors, as if expressly confirmed and ratified in writing by each of them. Without limiting the generality of the foregoing,
the Indemnification Representative shall have full power and authority to interpret all of the terms and provisions of this Agreement,
to compromise any claims asserted hereunder and to authorize any release of the Escrow Shares to be made with respect thereto,
on behalf of the Indemnifying Stockholders and their successors.

(d)         After
Closing Date, the majority vote of the Indemnifying Stockholders may terminate the Indemnification Representative and appoint
a successor Indemnification Representative in accordance with the terms of Section 7(b) above.

(e)         The
Escrow Agent may rely on the Indemnification Representative as the exclusive agent of the Indemnifying Stockholders under this
Agreement and shall incur no liability to any party with respect to any action taken or suffered by it in good faith reliance
thereon.

8.         
Amounts Payable by Indemnifying Stockholders. The amounts payable by the Indemnifying Stockholders under this Agreement (i.e.,
the indemnification obligations pursuant to Section 6(b)) shall be payable solely as follows. The Escrow Agent shall notify the
Indemnification Representative of any such amount payable by the Indemnifying Stockholders as soon as it becomes aware that any
such amount is payable, with a copy of such notice to the Parent. On the sixth business day after the delivery of such notice,
the Escrow Agent shall sell such number of Escrow Shares (up to the number of Escrow Shares then available in the Escrow Account),
subject to compliance with all applicable securities laws, as is necessary to raise such amount, and shall be entitled to apply
the proceeds of such sale in satisfaction of such indemnification obligations of the Indemnifying Stockholders; provided that
if the Indemnification Representative delivers to the Escrow Agent (with a copy to the Parent), within five business days after
delivery of such notice by the Indemnification Representative, a written notice contesting the legitimacy or reasonableness of
such amount, then the Escrow Agent shall not sell Escrow Shares to raise the disputed portion of such claimed amount except in
accordance with the terms of clauses (i) or (ii) of Section 3(a).

9.
         Termination. This Agreement shall terminate upon the distribution by
the Escrow Agent of all of the Escrow Shares in accordance with this Agreement; provided that the provisions of Sections 6 and
7 shall survive such termination.

10.         Notices.
All notices, instructions and other communications given hereunder or in connection herewith shall be in writing. Any such
notice, instruction or communication shall be sent either (i) by registered or certified mail, return receipt requested, postage
prepaid, or (ii) via a reputable nationwide overnight courier service, in each case to the address set forth below. Any such notice,
instruction or communication shall be deemed to have been delivered five business days after it is sent by registered or certified
mail, return receipt requested, postage prepaid, or one business day after it is sent via a reputable nationwide overnight courier
service.

Escrow Agent. In the event the Escrow Agent becomes unavailable or unwilling to continue in its capacity herewith, the Escrow
Agent may resign and be discharged from its duties or obligations hereunder by delivering a resignation to the parties to this
Escrow Agreement, not less than 60 days prior to the date when such resignation shall take effect. The Parent may appoint a successor
Escrow Agent without the consent of the Indemnification Representative and may appoint any other successor Escrow Agent with the
consent of the Indemnification Representative, which shall not be unreasonably withheld. If, within such notice period, the Parent
provides to the Escrow Agent written instructions with respect to the appointment of a successor Escrow Agent and directions for
the transfer of any Escrow Shares then held by the Escrow Agent to such successor, the Escrow Agent shall act in accordance with
such instructions and promptly transfer such Escrow Shares to such designated successor. If no successor Escrow Agent is named

Escrow Agent may apply to a court of competent jurisdiction for appointment of a successor Escrow Agent.
