for
value received, DIGITAL TURBINE, INC. (f/k/a Mandalay Digital Group, Inc.), a Delaware corporation (“Digital”),
hereby certifies that North Atlantic SBIC IV, L.P., a Delaware limited partnership
(the “Registered Holder”), is entitled, subject to the terms set forth below, to purchase from Digital,
at any time on or after the Vesting Date (as defined in Section 1 below) and on or before the Expiration Date (as defined
in Section 6 below) shares of Digital’s Common Stock, par value $0.001 per share (“Digital Common Stock”),
at an exercise price per share (the “Exercise Price”) equal to $0.001 (subject to adjustment as
provided herein). The shares of stock issuable upon exercise of this Common Stock Purchase Warrant (“Warrant”)
are referred to hereinafter as the “Warrant Shares”.

 

This Warrant is issued pursuant
to, and is subject to the terms and conditions of, that certain Securities Purchase Agreement dated of even date herewith (as the
same may be amended, modified, supplemented, extended or restated, from time to time, the “Purchase Agreement”)
by and among Digital, the Registered Holder, and Appia, Inc. (“Appia”). All capitalized terms used though
not defined herein but defined in the Purchase Agreement shall have the meanings given to such terms in the Purchase Agreement.

 

1.           Vesting;
Number of Shares. This Warrant shall become fully vested on the date with is twelve (12)
months from the date hereof (the “Vesting Date”) if, and only if,
all interest, principal and other amounts owed to the Registered Holder pursuant to that certain Debenture issued by Appia on or
about the date hereof (the “Obligations”) pursuant to the Purchase
Agreement have not been paid in full on or before such Vesting Date. In the event the Obligations have been paid in full on or
before the Vesting Date, then effective upon payment of the Obligations, this Warrant shall expire and be of no further force or
effect. If this Warrant shall not have vested on the Vesting Date, then this Warrant shall automatically expire and be of no further
force or effect. If and when this Warrant is vested, subject to the other terms and conditions hereinafter set forth, the Registered
Holder shall then be entitled, upon surrender of this Warrant, to purchase from Digital up to Four Hundred Thousand (400,000)
shares of Digital Common Stock (subject to adjustment as provided herein).

2.            Exercise.

 

(a)          Manner
of Exercise. This Warrant may be exercised by the Registered Holder, in whole or in part, by surrendering this Warrant,
with the purchase/exercise form appended hereto as Exhibit A duly executed by such Registered Holder or by such Registered
Holder’s duly authorized attorney, at the principal office of Digital, or at such other office or agency as Digital may designate,
accompanied by payment in full of the aggregate Exercise Price payable in respect of the number of Warrant Shares purchased upon
such exercise (the “Purchase Price”). The Purchase Price may be paid by cash, check, wire transfer, or
by the surrender of promissory notes or other instruments representing indebtedness of Digital to the Registered Holder.

 

(b)          Effective
Time of Exercise. Each exercise of this Warrant shall be deemed to have been effected immediately prior to the close of business
on the day on which this Warrant shall have been surrendered to Digital as provided in Section 2(a) hereinabove. At such
time, the person or persons in whose name or names any certificates for Warrant Shares shall be issuable upon such exercise as
provided in Section 2(d) hereinbelow shall be deemed to have become the holder or holders of record of the Warrant Shares
to be represented by such certificates.

 

(c)          Net
Issue Exercise.

 

(i)          In
lieu of exercising this Warrant in the manner provided in Section 2(a) hereinabove, the Registered Holder may elect to receive
a number of Warrant Shares equal to the value of this Warrant (or the portion thereof being canceled) by surrender of this Warrant
at the principal office of Digital together with notice of such election on the purchase/exercise form appended hereto as Exhibit A
duly executed by such Registered Holder or such Registered Holder’s duly authorized attorney, in which event Digital shall
issue to such Registered Holder a number of Warrant Shares computed using the following formula:

 

	X =	Y (A - B)
	 	  A

 

	Where	X =	The number of Warrant Shares to be issued to the Registered Holder.
	 	 	 
	 	Y =	The number of shares of Warrant Shares purchasable under this Warrant or, if only a portion of the Warrant is being exercised, the portion of the Warrant being cancelled (at the date of such calculation).
	 	 	 
	 	A =	The fair market value of one Warrant Share (at the date of such calculation).
	 	 	 
	 	B =	The Exercise Price (as adjusted to the date of such calculation).

 

(ii)         For
purposes of this Section 2(c), the fair market value of one Warrant Share on the date of calculation shall mean:

 

    	- 2 -

    	 

    

 

(A)         as
of any particular date: (1) the volume weighted average of the closing sales prices of Digital Common Stock for such day on all
domestic securities exchanges on which Digital Common Stock may at the time be listed; (2) if there have been no sales of Digital
Common Stock on any such exchange on any such day, the average of the highest bid and lowest asked prices for Digital Common Stock
on all such exchanges at the end of such day; (3) if on any such day Digital Common Stock is not listed on a domestic securities
exchange, the closing sales price of Digital Common Stock as quoted on the OTC Bulletin Board, the Pink OTC Markets, or similar
quotation system or association for such day; or (4) if there have been no sales of Digital Common Stock on the OTC Bulletin Board,
the Pink OTC Markets, or similar quotation system or association on such day, the average of the highest bid and lowest asked prices
for Digital Common Stock quoted on the OTC Bulletin Board, the Pink OTC Markets or similar quotation system or association at the
end of such day; in each case, averaged over twenty (20) consecutive Business Days ending on the Business Day immediately prior
to the day as of which fair market value is being determined; provided, that if Digital Common Stock is listed on any domestic
securities exchange, the term "Business Day" as used in this sentence means Business Days on which such exchange is open
for trading.

 

(B)         if
item (A) hereinabove is not applicable, then the fair market value of a Warrant Share shall be the highest price per share which
Digital could obtain on the date of calculation from a hypothetical willing, able, sophisticated and experienced buyer (but not
a current employee or director), acting at arms length in an open and unrestricted market, when neither is under compulsion to
buy or sell and when both have reasonable knowledge of all relevant facts, with such price to be determined in good faith by the
Digital Board and the Registered Holder, unless Digital is at such time subject to a Liquidity Event (as described in Section
7(d) below) in which case the fair market value of a Warrant Share shall be deemed to be the value received by the holders
of such stock pursuant to such event. If Digital, on the one hand, and the Registered Holder, on the other hand, cannot agree upon
the fair market value of a Warrant Share under this paragraph, then the dispute shall be settled by the appointment of an independent
third-party arbitrator in accordance with the rules of the American Arbitration Association.

 

(d)          Delivery
to Holder. As soon as practicable after the exercise of this Warrant in whole or in part, and in any event within ten
(10) days thereafter, Digital at its expense shall cause to be issued in the name of, and delivered to, the Registered Holder:

 

(i)          a
certificate or certificates for the number of Warrant Shares to which such Registered Holder shall be entitled, and

 

(ii)         in
case such exercise is in part only, a new warrant or warrants (dated the date hereof) of like tenor and calling in the aggregate
on the face or faces thereof for the number of Warrant Shares equal (without giving effect to any adjustment therein) to the number
of such shares called for on the face of this Warrant minus the number of such shares purchased by the Registered Holder upon such
exercise as provided in Section 2(a) or 2(c) hereinabove (without giving effect to any adjustment thereto).

 

(e)          Payment
of Dividends. If, between the issue and exercise dates of this Warrant:

 

    	- 3 -

    	 

    

 

(i)          Digital
shall have declared and paid dividends on Digital Common Stock, then upon exercise of this Warrant, the Registered Holder shall
be entitled to receive payment from Digital of an amount equal to any dividend payment to which such Registered Holder would have
been entitled if such Registered Holder had exercised this Warrant prior to the declaration and payment of said dividends; and

 

(ii)         any
dividends shall have accrued on Digital Common Stock, or shall have been declared on Digital Common Stock but be unpaid thereon,
then, upon exercise of this Warrant, the Warrant Shares shall automatically and without further action on the part of Digital or
the Registered Holder (unless the Registered Holder otherwise agrees) be deemed to have accrued an amount of dividends that would
have accrued on such Warrant Shares if such Warrant Shares had been issued on the date hereof and be entitled to receive payment
from Digital of an amount equal to any declared, but unpaid, dividend at the same time, and on the same terms and conditions, as
the other holders of Digital Common Stock.

 

3.            Adjustments.

 

(a)          Stock
Splits and Dividends. If outstanding shares of Digital Common Stock shall be subdivided into a greater number of shares
of Digital Common Stock or other Capital Stock of Digital, or a dividend of other or additional Capital Stock or other securities
or property (other than cash) of Digital shall be paid in respect of such Digital Common Stock, then the Exercise Price in effect
immediately prior to such subdivision or at the record date of such dividend shall simultaneously with the effectiveness of such
subdivision or immediately after the record date of such dividend be proportionately reduced. If outstanding shares of Digital
Common Stock shall be combined into a smaller number of shares, then the Exercise Price in effect immediately prior to such combination
shall, simultaneously with the effectiveness of such combination, be proportionately increased. When any adjustment is required
to be made in the Exercise Price, the number of Warrant Shares purchasable upon the exercise of this Warrant shall be changed to
the number determined by dividing (i) an amount equal to the number of shares issuable upon the exercise of this Warrant immediately
prior to such adjustment, multiplied by the Exercise Price in effect immediately prior to such adjustment, by (ii) the Exercise
Price in effect immediately after such adjustment. If an adjustment in the Exercise Price made hereunder would reduce the Exercise
Price to an amount below par value of Digital Common Stock, then such adjustment in Exercise Price made hereunder shall reduce
the Exercise Price to the par value of Digital Common Stock.

 

(b)          Reclassification,
Etc. In case there occurs any reclassification or change of the outstanding securities of Digital (or any other corporation
the stock or securities of which are at the time receivable upon the exercise of this Warrant) or any similar corporate reorganization
on or after the date hereof, then and in each such case the Registered Holder, upon the exercise hereof at any time after the consummation
of such reclassification, change or reorganization shall be entitled to receive, in lieu of the stock or other securities and property
receivable upon the exercise hereof prior to such consummation, the stock or other securities or property to which such Registered
Holder would have been entitled upon such consummation if such Registered Holder had exercised this Warrant immediately prior thereto,
all subject to further adjustment pursuant to the provisions of this Section 3.

 

    	- 4 -

    	 

    

 

(c)          Adjustment
Certificate. When any adjustment is required to be made to the Warrant Shares or the Exercise Price pursuant to this
Section 3, Digital shall promptly mail to the Registered Holder a certificate setting forth (i) a brief statement of the
facts requiring such adjustment, (ii) the Exercise Price after such adjustment, and (iii) the kind and amount of stock or other
securities or property into which this Warrant shall be exercisable after such adjustment.

 

(d)          Acknowledgement.
For the avoidance of doubt, it is acknowledged that the holder of this Warrant shall be entitled to the benefit of all adjustments
pursuant to this Section 3 which occur after the date hereof and prior to the exercise of this Warrant.

 

4.            Assignment.

 

(a)          The
holder of this Warrant acknowledges that this Warrant has not been registered under the Securities Act of 1933, as amended (the
“Securities Act”), and agrees not to sell, pledge, distribute, offer for sale, transfer or otherwise
dispose of this Warrant in the absence of (i) an effective registration statement under the Securities Act as to this Warrant and
registration or qualification of this Warrant under any applicable U.S. federal or state securities law then in effect, or (ii)
an opinion of counsel, reasonably satisfactory to Digital, that such registration and qualification are not required.

 

(b)          This
Warrant is not assignable by the Registered Holder without Digital’s prior written consent, except that assignments by the
Registered Holder to an Affiliate (as defined below) of the Registered Holder shall be permitted provided that the assignee agrees
in writing to be bound by all of the terms of this Warrant. For purposes of the foregoing, an “Affiliate” of the Registered
Holder shall mean any other person or entity who directly or indirectly, controls, is controlled by, or is under common control
with the Registered Holder, including, without limitation, any general partner, managing member, officer, or director of such Registered
Holder, or any venture capital fund now or hereafter existing which is controlled by one or more general partners or managing members
of, or shares the same management company with, the Registered Holder.

 

5.            No
Impairment. Without the prior written consent of the Registered Holder, Digital shall not
avoid or seek to avoid the observance or performance of any of the terms of this Warrant.

 

6.            Termination.

 

(a)          Provided
that the Registered Holder receives prior notices in accordance with Section 7 below, and subject to Section 6(b)
and Section 6(c) hereinbelow, this Warrant (and the right to purchase securities upon exercise hereof) shall terminate on
the earliest to occur of the following (the “Expiration Date”):

 

(i)          5:00
P.M. Boston, Massachusetts time on March 5, 2025; or

 

(ii)         the
occurrence of any Liquidity Event following the Vesting Date.

 

    	- 5 -

    	 

    

 

(b)          If
on the Expiration Date this Warrant has not been exercised in full and the fair market value of one Warrant Share (or other security
issuable upon the exercise hereof) as determined in accordance with Section 2(c) above is greater than the Exercise Price
in effect on such date, then this Warrant shall automatically be deemed on and as of such date to be exercised and converted pursuant
to Section 2(c) into Warrant Shares, and Digital shall promptly deliver a certificate representing such Warrant Shares.

 

(c)          If
a Liquidity Event occurs prior to the Vesting Date, then (i) Digital shall reserve and set aside an amount of the consideration
payable in respect of such Liquidity Event, which would otherwise be distributed to Digital’s Stockholders, sufficient to
pay to the Registered Holder the full amount of payment such holder would have been entitled to had this Warrant been fully vested
at the time of the Liquidity Event (the “Liquidity Payment”), and (ii) if this Warrant subsequently vests,
then this Warrant shall automatically be deemed on and as of the Vesting Date to be exercised and converted pursuant to Section
2(c) into Warrant Shares (subject to any adjustments resulting from such Liquidity Event or other events under Section 3),
and Digital shall, at the option of the Registered Holder, promptly deliver the a certificate representing such Warrant Shares
or the Liquidity Payment. In lieu of the foregoing, Digital may elect to accelerate vesting of this Warrant.

 

7.            Notices
of Certain Transactions. In case:

 

(a)          Digital
shall set a record date for the holders of its Capital Stock (or other stock or securities at the time deliverable upon the exercise
of this Warrant) for the purpose of entitling or enabling them to receive any dividend or other distribution, or to receive any
right to subscribe for or purchase any shares of stock of any class or any other securities, or to receive any other right, to
subscribe for or purchase any shares of stock of any class or any other securities, or to receive any other right, or

 

(b)          Digital
shall set an effective date of any capital reorganization of Digital, any reclassification of the Capital Stock of Digital, any
consolidation or merger of Digital, any consolidation or merger of Digital with or into another corporation (other than a consolidation
or merger in which Digital is the surviving entity), or any transfer of all or substantially all of the assets of Digital, or

 

(c)          Digital
shall set an effective date of any redemption of any Capital Stock of Digital (or other stock or securities at the time deliverable
upon the exercise of this Warrant), or

 

(d)          Digital
shall set an effective date of any Liquidity Event,

 

then, and in each such case, Digital will mail
or cause to be mailed to the Registered Holder of this Warrant a notice specifying, as the case may be, (i) the record date for
the purpose of such dividend, distribution or right, and stating the amount and character of such dividend, distribution or right,
or (ii) the effective date on which such Liquidity Event, reorganization, reclassification, consolidation, merger, transfer, dissolution,
liquidation, winding-up, or redemption is to take place, and the time, if any is to be fixed, as of which the holders of record
of Capital Stock (or such other stock or securities at the time deliverable upon such reorganization, reclassification, consolidation,
merger, transfer, dissolution, liquidation, winding-up, redemption or conversion) are to be determined. Such notice shall be given
at least ten (10) Business Days prior to the record date or effective date for the event specified in such notice.

 

    	- 6 -

    	 

    

 

Such notice shall specify
all material terms of the event specified in such notice. If any material term changes after such notice is given, or such notice
fails to include any such material term, such notice shall be void and Digital shall be obligated to provide a new notice to the
Registered Holder pursuant to the terms of this Section 7.

 

8.            Sale
of Company. If following the Vesting Date, Digital shall at any time prior to the Expiration
Date undergo a Liquidity Event, it shall provide the Registered Holder the ten (10) Business Days prior written notice of the Liquidity
Event as required by Section 7 above, then the Registered Holder shall have until the effective date of such Liquidity
Event (the “Sale Exercise Date”) to exercise this Warrant in accordance
with the provisions of Section 2 above.

 

9.            Intentionally
Deleted.

 

10.         Replacement
of Warrant. Upon receipt of evidence reasonably satisfactory to Digital of the loss, theft,
destruction or mutilation of this Warrant and (in the case of loss, theft or destruction) upon delivery of an indemnity agreement
(with surety if reasonably required) in a form reasonably satisfactory to Digital, or (in the case of mutilation) upon surrender
and cancellation of this Warrant, Digital will issue, in lieu thereof, a new Warrant of like tenor.

 

11.         Mailing
of Notices. Any notice required or permitted pursuant to this Warrant shall be in writing
and shall be deemed sufficient upon delivery pursuant to Section 11.5 of the Purchase Agreement.

 

12.         No

of Incorporation, or (ii) the Purchase Agreement, until the exercise of this Warrant, the Registered Holder of this Warrant shall
not solely by virtue of holding this Warrant have or exercise any rights as a Stockholder of Digital.

 

13.         No
Fractional Shares. No fractional shares of Digital Common Stock (or other stock or securities

SECURITIES PURCHASE AGREEMENT

 

THIS SECURITIES PURCHASE AGREEMENT
is made as of March 6, 2015, by and among (i) Appia, Inc., a Delaware corporation (“Appia”), (ii) Digital
Turbine, Inc. (f/k/a Mandalay Digital Group, Inc.), a Delaware corporation (“Digital” and together
with Appia, the “Companies” with each, a “Company”), and (iii) North Atlantic
SBIC IV, L.P., a Delaware limited partnership (the “Purchaser” and collectively with the Companies,
the “Parties” with each, a “Party”).

 

WHEREAS, on April 4, 2013, Appia
and the Purchaser entered into a certain Purchase Agreement, pursuant to which, among other things, Appia issued to the Purchaser
a Subordinated Debenture in the amount of $5,000,000 (the “First Debenture”);

 

WHEREAS, on October 31, 2013, Appia
and the Purchaser entered into another Purchase Agreement, pursuant to which, among other things, Appia issued to the Purchaser
another Subordinated Debenture in the amount of $3,000,000 (the “Second Debenture”);

 

WHEREAS, on or about November 13,
2014, a certain Agreement and Plan of Merger was entered into among Appia, Digital and the other parties thereto (the “Merger
Agreement”), pursuant to which, among other things, Digital is directly or indirectly acquiring substantially all
of the voting control of Appia (the “Acquisition”); and

 

WHEREAS, in connection and simultaneously
with consummation of the Acquisition, the Parties are entering into this Agreement in order to, among other things, provide for
the contribution and exchange of the First Debenture and the Second Debenture for a Subordinated Secured Debenture newly issued
by Appia to the Purchaser and guaranteed by Digital.

 

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

 

SECTION
1.      DEFINITIONS.  

 

All capitalized terms
not defined herein but defined in Appendix A attached hereto shall have the meanings given to such terms in Appendix
A. All terms defined in this Agreement shall also have such defined meanings when used in the other Financing Documents or
any certificate or other document made or delivered pursuant hereto or thereto, unless otherwise specified herein or therein.

 

All references in this
Agreement to Sections, Subsections, Exhibits, Schedules and Appendices refer to the Sections, Subsections, Exhibits, Schedules
and Appendices of this Agreement unless otherwise indicated. All Exhibits, Schedules and Appendices attached to this Agreement
are incorporated herein and made a part hereof.

 

SECTION
2.      THE NEW DEBENTURE.

 

2.1             
Sale and Purchase. Subject to the terms and conditions hereof, and in exchange for the First Debenture and the
Second Debenture, Appia shall sell, issue and deliver to the Purchaser, and the Purchaser shall receive from Appia, a Subordinated
Secured Debenture (the “New Debenture”) in the aggregate principal amount of Eight Million and 00/100
Dollars ($8,000,000.00) (the “Commitment”). The New Debenture shall be substantially in the form
of Exhibit A attached hereto, shall be duly executed by Appia, shall be dated as of the date of the consummation of
the Acquisition pursuant to the Merger Agreement (the “Closing Date”), and shall be made payable to the
order of the Purchaser in the amount of the Commitment. Contemporaneously with the issuance of the New Debenture, Appia shall pay
in full all amounts of accrued but theretofore unpaid interest then outstanding on the First Debenture and the Second Debenture
and all applicable prepayment premiums in respect of the First Debenture and the Second Debenture. The closing of the contribution
and exchange of the First Debenture and the Second Debenture and the issuance of the New Debenture, the Common Shares, and the
Warrant under this Agreement shall take place remotely via the mutual exchange of documents and signatures if and when all conditions
precedent set forth herein have been satisfied or waived and simultaneously with the closing of the Acquisition pursuant to the
Merger Agreement on the Closing Date, or at such other time and place as the Parties may mutually agree (the “Closing”).

 

    	-1-

    	 

    

 

2.2             
Subordination. Appia hereby represents that Appia and its Subsidiaries, if any exist, currently owe the Indebtedness
set forth on Schedule 2.2 (which does not and shall not exceed Five Million and 00/100 Dollars ($5,000,000.00) of Senior
Debt, and does not and shall not exceed One Million and 00/100 Dollars ($1,000,000.00) in Purchase Money Indebtedness) (“Existing
Senior Debt”) which is secured by the assets set forth on Schedule 2.2. As of the Closing, Appia and its Subsidiaries,
if any exist, shall have no Senior Debt other than the Existing Senior Debt set forth on Schedule 2.2 (which does not and
shall not exceed Five Million and 00/100 Dollars ($5,000,000.00) of Senior Debt, and does not and shall not exceed One Million
and 00/100 Dollars ($1,000,000.00) in Purchase Money Indebtedness). At such time as the Senior Debt is less than Five Million and
00/100 Dollars ($5,000,000.00) in the aggregate, if Appia desires to incur Senior Debt not set forth on Schedule 2.2 (“New
Senior Debt”), the Purchaser shall agree to subordinate the payment of the principal of and interest on the New Debenture
in a commercially reasonable manner, substantially pursuant to the terms of a subordination agreement described in the following
sentence, to the payment of such New Senior Debt incurred by Appia in an amount which, together with all existing Senior Debt,
shall not exceed Five Million and 00/100 Dollars ($5,000,000.00). The Purchaser agrees, upon request of any future holder of such
New Senior Debt or Replacement Senior Debt, to enter into a commercially reasonable subordination agreement for the benefit of
such future holder of such New Senior Debt or Replacement Senior Debt; provided, however, that such subordination
agreement shall be on terms which are commercially reasonable and reasonably satisfactory to the Purchaser, as determined by the
Purchaser in its good faith discretion, and shall, among other provisions, permit payment of principal and interest under the New
Debenture according to its terms unless the Existing, New, or Replacement Senior Debt (as applicable) is in default under the terms
thereof.

 

2.3             
Use of Proceeds. The New Debenture shall be issued in exchange for the First Debenture and the Second Debenture.

 

2.4             
Interest Rate. Subject to the provisions of Section 2.5, the unpaid principal balance outstanding under
the New Debenture, from time to time during the first twelve (12) months following the Closing Date, shall accrue interest at
the rate of Ten and 00/100 Percent (10.00%) per annum. Subject to the provisions of Section 2.5, the unpaid principal
balance outstanding under the New Debenture, from time to time after the first twelve (12) months following the Closing Date, shall

the applicable Security Document to be, but is not, subject to the Liens created by the Security Documents, Appia shall, or shall
cause its relevant Subsidiaries to, as soon as possible and in no event later than thirty (30) days after the relevant acquisition
date and, to the extent permitted by applicable law, grant to the Purchaser a first priority (subject to Permitted Liens) Lien
on such property as collateral security for the Obligations pursuant to documentation reasonably satisfactory in form and substance
to the Purchaser. Appia, at its own expense, shall execute, acknowledge and deliver, or cause the execution, acknowledgement and
delivery of, and thereafter register, file or record in an appropriate governmental office, any document or instrument (including
legal opinions, title insurance, consents and corporate documents) and take all such actions reasonably deemed by the Purchaser
to be necessary or desirable to ensure the creation, priority and perfection of such Lien.

 

8.12         
Prohibition of Liens. Without the consent of the Purchaser, Appia shall not, and Appia shall not permit any of
its Subsidiaries to, enter into with any Person any agreement (other than this Agreement and the other Financing Documents) which
prohibits or limits the ability of Appia or any of its Subsidiaries to create, incur, assume or suffer to exist any Lien (other
than Permitted Liens) upon the property or assets of Appia, whether now existing or hereafter arising, wherever such property or
assets may be located.

 

8.13         
New Subsidiaries. Except as permitted by Section 8.15(i), Appia shall not create or acquire any direct
or indirect Subsidiary without the express written consent of the Purchaser. With regard to any Subsidiary which the Purchaser
permits Appia to create or acquire, Appia shall cause, at its sole cost and expense, each such Subsidiary that is organized (unless
Purchaser otherwise consents in writing), immediately upon such creation or acquisition to execute and deliver to the Purchaser
the following agreements and documents, which agreements and documents shall be in form and substance reasonably satisfactory to
the Purchaser: (i) an instrument pursuant to which such Subsidiary shall become a guarantor of the Obligations, (ii) a security
agreement (it being acknowledged and agreed that such security agreement shall be substantially in the same form as the Appia Security
Agreement); (iii) any and all UCC financing statements which the Purchaser deems necessary and appropriate in order to implement
such security agreement; and (iv) such other agreements, documents, financing statements, instruments, opinions and certificates
and completion of such other matters, as the Purchaser may reasonably deem necessary or appropriate to assure that the Purchaser
shall have the same rights and protections with respect to such Subsidiary as they have with respect to the Companies and that
such Subsidiary shall be subject to the same obligations under the Financing Documents as the Companies.

Restricted Payments. Without the consent of the Purchaser, Appia shall not, and Appia shall not permit any of
its Subsidiaries to, declare or pay any dividend on, or make any payment on account of, or set apart assets for a sinking or other
analogous fund for, the purchase, redemption, defeasance, retirement or other acquisition of, any shares of any class of Capital
Stock of Appia or any or its Subsidiaries or any warrants or options to purchase any such shares of Capital Stock, whether now
or hereafter outstanding, or make any other distribution in respect thereof, either directly or indirectly, whether in cash or
property or in obligations of either Company or any of its Subsidiaries, in each case other than (i) repurchases of stock from
former employees or consultants pursuant to the terms of a previously existing written agreement with such employees and consultants
who performed services for Appia or any Subsidiary in connection with the cessation of such employment or service at no greater
than the original purchase price, provided that no such repurchase can occur without the Purchaser’s consent if an Event
of Default has occurred, is continuing or would exist after giving effect to the repurchase, (ii) wholly-owned Subsidiaries declaring
and paying dividends to Appia or other wholly-owned Subsidiaries, and (iii) Appia declaring and paying dividends to Digital.

 

8.15         
Limitation on Investments, Loans and Advances. Without the consent of the Purchaser, Appia shall not, and Appia
shall not permit any of its Subsidiaries to, make any advance, loan, extension of credit, or capital contribution to, or purchase

in, any Person (an “Investment”), except:

extensions of trade credit and endorsements of negotiable instruments and other negotiable documents in the ordinary course
of business;

 

(e)            
loans or advances to employees, officers or directors of Appia or any of its Subsidiaries, or guarantee the payment of any
such loan granted by a third party, in an aggregate amount for Appia and its Subsidiaries not to exceed Fifty Thousand Dollars
($50,000) at any time outstanding;

 

(f)            
Investments (including debt obligations) received in connection with the bankruptcy or reorganization of customers or suppliers
and in settlement of delinquent obligations of, and other disputes with, customers or suppliers arising in the ordinary course
of a Appia’s business;

 

(g)

of Appia in any Subsidiary;

 

    	-20-

    	 

    

 

(h)           
Additional Investments in an aggregate amount not to exceed One Hundred Thousand and 00/100 Dollars ($100,000.00) at any

with such Investments, become direct or indirect wholly-owned Subsidiaries of Appia; provided that no more than Four Hundred Thousand
and 00/100 Dollars ($400,000) of such Investment shall be funded with cash or Cash Equivalents.

 

8.16         
Limitation on Transactions with Affiliates. Appia shall not, and Appia shall not permit any of its Subsidiaries
to, enter into any transaction (including, without limitation, any purchase, sale, lease or exchange of property or the rendering
of any service) with any Affiliate unless such transaction (i) is otherwise permitted under this Agreement; or (ii)(A) is
in the ordinary course of Appia’s or such Subsidiary’s business or approved by a majority of the Appia Board who are
disinterested in such transaction; and (B) is upon fair and reasonable terms no less favorable to Appia or such Subsidiary,
as the case may be, than it would obtain in a comparable arm’s length transaction with a Person which is not an Affiliate;
provided, however, that the foregoing restriction shall not prohibit any employment agreement entered into by Appia
or any of its Subsidiaries in the ordinary course of business; any issuance of securities in connection with employment arrangements,
stock options and stock ownership plans of Appia entered into in the ordinary course of business or participation in future equity
financings of Appia. Nothing in this Section 8.16 prohibits any transaction otherwise permitted in this Agreement.

Senior Debt. Without the consent of the Purchaser, Appia shall not increase the aggregate amount of any debt
permitted by Section 8.1(a) above to an amount which at any time and in the aggregate exceeds the sum of Six Million and
00/100 Dollars ($6,000,000.00), and of which Senior Debt shall not exceed Five Million Dollars ($5,000,000) and Purchase Money

(a)            
the following events, as soon as practicable and in any event within thirty (30) days after Appia has knowledge thereof:
(i) the occurrence or expected occurrence of any Reportable Event with respect to any Plan, a failure to make any required contribution
to a Plan, the creation of any Lien in favor of the PBGC or a Plan or (ii) the institution of proceedings or the taking of any

payment comes due in accordance with the terms of this Agreement and the other Financing Documents; or Appia shall fail to pay
any other amount payable hereunder when due (other than an Interest Default permitted by Section 2.5(a)); or

 

(b)           
any representation or warranty made by a Company or any other Obligor herein or in any other Financing Document or which

Appia or any Subsidiary shall be in default in the observance or performance of any other covenant contained in this Agreement

or securing any Indebtedness of such Company which, together with all such other due but unpaid Indebtedness, exceeds the sum of

declaration of an event of default under any agreement relating to such Indebtedness; or

 

(f)            
a Company or any Subsidiary, (i) shall make an assignment for the benefit of creditors; or (ii) shall admit in writing its

for such restoration or replacement; or

 

(m)         
any default shall exist and remains unwaived, unforborn or uncured with respect to any of the Senior Debt or Replacement
Senior Debt if, as a result of such default, any holder of the Senior Debt or Replacement Senior Debt, is entitled and elects to
cause any such Senior Debt or Replacement Senior Debt to become due prior to its stated date of maturity; or

 

(n)           
any payment which a Company knew or should have known was be made in violation of any subordination agreement entered into
between the Purchaser and another holder of Company Indebtedness or Company Subsidiary Indebtedness; or

the New Debenture, and the other Financing Documents to be, and they shall thereupon forthwith become, immediately due and payable
without presentment, demand, protest or other notice of any kind, all of which are hereby expressly waived by the Companies; provided,
however, that in the event of any Event of Default specified in Section 9.1(f), Section 9.1(g) or Section

the Purchaser.

Effect of Schedules and Loan Agreement Representations. For the avoidance of doubt and notwithstanding the consummation
of the Closing by the Purchaser or anything else contained herein or in the Financing Documents: (i) no circumstance, condition,
subject, item, occurrence or other matter which constitutes an Event of Default under this Agreement or the other Financing Documents
shall be deemed waived by virtue of it having been set forth on the Master Disclosure Schedule or any other disclosure schedule
delivered in connection with this Agreement or the other Financing Documents; and (ii) whether an Event of Default has occurred
shall be determined without regard to any disclosure set forth on the Master Disclosure Schedule or any other disclosure schedule
delivered in connection with this Agreement or the other Financing Documents (but any circumstance, condition, subject, item, occurrence
or other matter disclosed therein will be acknowledged by Borrower to have occurred for purposes of identifying an Event of Default).

SECTION
10.  RIGHTS AND REMEDIES.

Rights of Purchaser. Upon the occurrence and during the continuance of any one or more of the Events of Default,
the Purchaser may proceed in accordance with applicable law to enforce the legal or equitable rights or remedies as it may have
under this Agreement or any other Financing Documents or otherwise by virtue of applicable law.

 

10.2         
Setoff and Adjustments. In addition to any rights and remedies of the Purchaser provided by law, the Purchaser
shall have the right, without prior notice to either Company, any such prior notice being expressly waived by each Company to the
extent permitted by applicable law, upon any amount becoming due and payable by a Company hereunder (whether at the stated maturity,
by acceleration or otherwise) to set-off and appropriate and apply against such amount then due and payable any and all deposits
(general or special, time or demand, provisional or final), in any currency, and any other credits, indebtedness or claims, in
any currency, in each case whether direct or indirect, absolute or contingent, at any time held or owing by the Purchaser or any
branch or agency thereof to or for the credit or the account of a Company. The Purchaser agrees to promptly notify the Companies
after any such set-off and application made by the Purchaser, provided that the failure to give such notice shall not affect the
validity of such set-off and application.

 

10.3         
No Waiver; Cumulative Remedies. No failure to exercise and no delay in exercising on the part of the Purchaser,
any right, remedy, power or privilege hereunder or under the other Financing Documents shall operate as a waiver thereof; nor shall
any single or partial exercise of any right, remedy, power or privilege hereunder preclude any other or further exercise thereof
or the exercise of any other right, remedy, power or privilege. The rights, remedies, powers and privileges herein provided are
cumulative and not exclusive of any rights, remedies, powers and privileges provided by law.

 

10.4         
Distribution of Collateral Proceeds. In the event that, following the occurrence and during the continuance of
any Event of Default, the Purchaser receives any monies in connection with the enforcement of any of the Security Documents, or
otherwise with respect to the realization upon any of the Collateral, such monies shall be distributed for application as follows:
(i) first, to the Obligations in such order or preference as the Purchaser may determine; (ii) second, upon payment
and satisfaction in full or other provisions for payment in full satisfaction of all of the Obligations, to the payment of any
obligations required to be paid pursuant to §9-615 of the UCC; and then (c) third, the excess, if any, shall be returned
to the applicable Company or to such other Persons as are entitled thereto.

 

SECTION
11.  MISCELLANEOUS.

 

11.1         
Amendments and Waivers. Neither this Agreement nor any other Financing Document or the Warrant, nor any terms
hereof or thereof may be amended, supplemented or modified except in a writing signed by the Parties. No provision of this Agreement
or of any other Financing Document or of the Warrant, or any terms hereof or thereof, may be waived except in a writing signed
by the party waiving its rights. In the case of any waiver, the Parties shall be restored to their former positions and rights
hereunder and under the other Financing Documents, and any Default or Event of Default waived shall be deemed to be cured and not
continuing; no such waiver shall extend to any subsequent or other Default or Event of Default or impair any right consequent thereon.

 

11.2         
Survival of Covenants. Except for those which by their terms survive termination of the Financing Documents or
for another period of time, all agreements, representations, covenants and warranties made by a Company in the Financing Documents
shall remain in full force and effect until all Obligations (other than inchoate indemnity obligations) have been paid in full
and satisfied, notwithstanding the fact that the New Debenture may, from time to time, be in a zero or credit position.

 

    	-25-

    	 

    

 

11.3         
Prior Discussions; Counterparts. The Financing Documents and the Warrant incorporate all discussions and negotiations
between the Parties and either express or implied, concerning the Obligations, notwithstanding any custom, usage or oral agreement
or understanding to the contrary. This Agreement may be executed in two or more counterparts, each of which shall constitute an
original, but such counterparts together shall constitute one and the same instrument. Any proof of this Agreement shall require
production of only one such counterpart.

 

11.4         
Severability. Any provision of this Agreement which is prohibited or unenforceable in any jurisdiction shall,
as to such jurisdiction, be ineffective to the extent of such prohibition or unenforceability without invalidating the remaining
provisions hereof, and any such prohibition or unenforceability in any jurisdiction shall not invalidate or render unenforceable
such provision in any other jurisdiction.

 

11.5

(b)           
In addition, the Companies agree to pay all reasonable out-of-pocket expenses (including without limitation reasonable attorneys’
fees and costs and reasonable accounting and similar professional fees and charges) incurred by the Purchaser in connection with
the enforcement of or preservation of rights under any of the Financing Documents against a Company or any Subsidiary (including

APPENDIX B

 

1.1  Shelf Registration.

 

(a) As promptly as
reasonably possible, and in any event on or prior to the later of (i) the 15th Business Day after the Closing Date or
(ii) the 5th Business Day after the date on which all audited financial statements required to be included in or incorporated
by reference into the Registration Statement (as such term is hereinafter defined) are available (in either case, the “Filing
Date”), Digital shall prepare and file with the SEC a "shelf" Registration Statement covering the resale of all
Common Shares and Warrant Shares (collectively, the “Registrable Securities”) for an offering to be made on a continuous
basis pursuant to Rule 415 (the “Registration Statement”). If for any reason the SEC does not permit all of the Registrable
Securities to be included in such Registration Statement, then Digital shall prepare and file with the SEC a separate Registration
Statement with respect to any such Registrable Securities not included with the initial Registration Statements, as expeditiously
as possible, but in no event later than the date which is 30 days after the date on which the SEC shall indicate as being the first
date such filing may be made. The Registration Statement shall be on Form S-3; in the event Form S-3 is not available for the registration
of the resale of Registrable Securities hereunder, Digital shall (i) register the resale of the Registrable Securities on another
appropriate form in accordance herewith as the Purchaser may consent and (ii) attempt to register the Registrable Securities on
Form S-3 as soon as such form is available, provided that Digital shall maintain the effectiveness of the Registration Statements
then in effect until such time as a Registration Statement on Form S-3 covering the Registrable Securities has been declared effective
by the SEC.

 

(b) Digital shall use
its best efforts to cause the Registration Statement to be declared effective by the SEC as promptly as reasonably possible after
the filing thereof, and shall use its best efforts to keep the Registration Statement continuously effective under the Securities
Act until the earlier of (i) the third anniversary of the date that the Registration Statement is first declared effective by the
SEC (the “Effective Date”), (ii) the date when all Registrable Securities covered by such Registration Statement have
been sold publicly, or (iii) the date on which the Registrable Securities are eligible for sale without registration and without
volume limitation pursuant to Rule 144 (the "Effectiveness Period"); provided, however, that if the Warrant expires on
or before the Vesting Date (as such term is defined in the Warrant) because the Obligations (as such term is defined in the Warrant)
have been paid in full, then the Effectiveness Period shall expire no later than the second anniversary of the Effective Date.
Digital shall notify the Purchaser in writing promptly (and in any event within one Business Day) after receiving notification
from the SEC that the Registration Statement has been declared effective.

 

(c) As promptly as
reasonably possible, and in any event no later than the 7th day after the Registration Statement ceases to be effective
pursuant to applicable securities laws due to the passage of time or the occurrence of an event requiring Digital to file a post-effective
amendment to the Registration Statement, Digital shall prepare and file with the SEC a post-effective amendment to the Registration
Statement (a “Post-Effective Amendment”). Digital shall use its best efforts to cause the Post-Effective Amendment
to be declared effective by the SEC as promptly as possible after the filing thereof. Digital shall notify the Purchaser in writing
promptly (and in any event within one Business Day) after receiving notification from the SEC that the Post-Effective Amendment
has been declared effective.

 

1.2Registration Procedures.
In connection with Digital's registration obligations hereunder, Digital shall:

 

(a) Not less than three
days prior to the filing of a Registration Statement or any related Prospectus or any amendment or supplement thereto (including
any document that would be incorporated or deemed to be incorporated therein by reference), Digital shall (i) furnish to the Purchaser
and Nixon Peabody LLP (“Purchaser Counsel”) 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 the Purchaser and Purchaser
Counsel, and (ii) cause its officers and directors, counsel and independent certified public accountants to respond to such inquiries
as shall be necessary, in the reasonable opinion of Purchaser Counsel, to conduct a reasonable investigation within the meaning
of the Securities Act. Digital shall not file a Registration Statement or any such Prospectus or any amendments or supplements
thereto to which Purchaser shall reasonably object.

 

    	B-1

    	 

    

 

(b) (i) Prepare and
file with the SEC such amendments, including Post-Effective Amendments, to each Registration Statement and the Prospectus used
in connection therewith as may be necessary to keep the Registration Statement continuously effective for the Effectiveness Period
and prepare and file with the SEC 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, and as so supplemented or amended to be filed pursuant to Rule 424; (iii) respond as promptly as reasonably possible,
and in any event within ten days, to any comments received from the SEC with respect to the Registration Statement or any amendment
thereto and as promptly as reasonably possible provide the Purchaser true and complete copies of all correspondence from and to
the SEC relating to the Registration Statement; and (iv) comply in all material respects with the provisions of the Securities
Act and the Exchange Act with respect to the disposition of all Registrable Securities covered by the Registration Statement during
the applicable period in accordance with the intended methods of disposition by the Purchaser thereof set forth in the Registration
Statement as so amended or in such Prospectus as so supplemented.

 

(c) Notify the Purchaser
and Purchaser Counsel as promptly as reasonably possible, and confirm such notice in writing no later than one day thereafter,
of any of the following events: (i) the SEC notifies Digital whether there will be a "review" of any Registration Statement;
(ii) the SEC comments in writing on any Registration Statement (in which case Digital shall deliver to the Purchaser and Purchaser
Counsel a copy of such comments and of all written responses thereto); (iii) any Registration Statement or any Post-Effective Amendment
is declared effective; (iv) the SEC or any other federal or state governmental authority requests any amendment or supplement to
any Registration Statement or Prospectus or requests additional information related thereto; (v) the SEC issues any stop order
suspending the effectiveness of any Registration Statement or initiates any proceedings for that purpose; (vi) Digital receives
notice of any suspension of the qualification or exemption from qualification of any Registrable Securities for sale in any jurisdiction,
or the initiation or threat of any proceeding for such purpose; or (vii) the financial statements included or incorporated by reference
in any Registration Statement become ineligible for inclusion or incorporation therein or any statement made in any Registration
Statement or Prospectus or any document incorporated or deemed to be incorporated therein by reference is untrue in any material
respect or any revision to a Registration Statement, Prospectus or other document is required so that 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 the light of the circumstances under which they were made, not misleading.

 

(d) Use its best efforts
to avoid the issuance of or, if issued, obtain the withdrawal of (i) any order suspending the effectiveness of any Registration
Statement, or (ii) any suspension of the qualification (or exemption from qualification) of any of the Registrable Securities for
sale in any jurisdiction, as soon as possible.

 

(e) Furnish to the
Purchaser and Purchaser Counsel, without charge, at least one conformed copy of each Registration Statement and each amendment
thereto, including financial statements and schedules, all documents incorporated or deemed to be incorporated therein by reference,
and all exhibits (including those previously furnished or incorporated by reference) promptly after the filing of such documents
with the SEC.

 

    	B-2

    	 

    

 

(f) Promptly deliver
to the Purchaser and Purchaser Counsel, without charge, as many copies of the Prospectus or Prospectuses (including each form of
prospectus) and each amendment or supplement thereto as they may reasonably request. Digital hereby consents to the use of such
Prospectus and each amendment or supplement thereto by each of the Purchaser in connection with the offering and sale of the Registrable
Securities covered by such Prospectus and any amendment or supplement thereto.

 

(g) (i) In the time
and manner required by each Trading Market, prepare and file with such Trading Market an additional shares listing application
covering all of the Registrable Securities; (ii) take all steps necessary to cause such Registrable Securities to be approved for
listing on each Trading Market as soon as possible thereafter; (iii) provide to the Purchaser evidence of such listing; and (iv)
maintain the listing of such Registrable Securities on each such Trading Market or another Eligible Market.

 

(h) Prior to any public
offering of Registrable Securities, use its best efforts to register or qualify or cooperate with the Purchaser and Purchaser Counsel
in connection with the registration or qualification (or exemption from such registration or qualification) of such Registrable
Securities for offer and sale under the securities or Blue Sky laws of such jurisdictions within the United States as any Purchaser
requests in writing, to keep each such registration or qualification (or exemption therefrom) effective during the Effectiveness
Period and to do any and all other acts or things necessary or advisable to enable the disposition in such jurisdictions of the
Registrable Securities covered by a Registration Statement.

 

(i) Cooperate with
the Purchaser 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 this Agreement,
of all restrictive legends, and to enable such Registrable Securities to be in such denominations and registered in such names
as any the Purchaser may request.

 

(j) Upon the occurrence
of any event described in Section 1.2(c)(vii), as promptly as reasonably possible, prepare a supplement or amendment, including
a post-effective amendment, to the 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
the 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 the light of the circumstances under which they
were made, not misleading.

 

(k) Cooperate with
any due diligence investigation undertaken by the Purchaser in connection with the sale of Registrable Securities, including, without
limitation, by making available any documents and information; provided that Digital will not deliver or make available to any
Purchaser material, nonpublic information unless the Purchaser specifically requests in advance to receive material, nonpublic
information in writing.

 

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

    	B-3

    	 

    

 

1.4 Indemnification.

 

(a) Indemnification
by Digital. Digital shall, notwithstanding any termination of this Agreement, indemnify and hold harmless the Purchaser, the
officers, directors, partners, members, agents, brokers (including brokers who offer and sell Registrable Securities as principal
as a result of a pledge or any failure to perform under a margin call of Common Stock), investment advisors and employees of each
of them, each Person who controls the Purchaser (within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange
Act) and the officers, directors, partners, members, agents and employees of each such controlling Person, to the fullest extent
permitted by applicable law, from and against any and all Losses, as incurred, arising out of or relating to any untrue or alleged
untrue statement of a material fact contained in the 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
form of prospectus or supplement thereto, in the light of the circumstances under which they were made) not misleading, except
to the extent, but only to the extent, that (i) such untrue statements, alleged untrue statements, omissions or alleged omissions
are based solely upon information regarding the Purchaser furnished in writing to Digital by the Purchaser expressly for use therein,
or to the extent that such information relates to the Purchaser or the Purchaser's proposed method of distribution of Registrable
Securities and was reviewed and expressly approved in writing by the Purchaser expressly for use in the Registration Statement,
such Prospectus or such form of Prospectus or in any amendment or supplement thereto or (ii) in the case of an occurrence of an
event of the type specified in Section 1.2(c)(v)-(vii), the use by the Purchaser of an outdated or defective Prospectus after
Digital has notified the Purchaser in writing that the Prospectus is outdated or defective and prior to the receipt by the Purchaser
of the Advice contemplated in Section 1.5.

 

(b) Indemnification
by Purchaser. The Purchaser shall indemnify and hold harmless Digital, its directors, officers, agents and employees, each
Person who controls Digital (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 determined by a court of competent jurisdiction in a final judgment not subject to appeal or review) arising
solely out of any untrue statement of a material fact contained in the Registration Statement, any Prospectus, or any form of prospectus,
or in any amendment or supplement thereto, or arising solely out of any omission of a material fact required to be stated therein
or necessary to make the statements therein (in the case of any Prospectus or form of prospectus or supplement thereto, in the
light of the circumstances under which they were made) not misleading to the extent, but only to the extent, that such untrue statement
or omission is contained in any information so furnished in writing by the Purchaser to Digital specifically for inclusion in such
Registration Statement or such Prospectus or to the extent that (i) such untrue statements or omissions are based solely upon information
regarding the Purchaser furnished in writing to Digital by the Purchaser expressly for use therein, or to the extent that such
information relates to the Purchaser or the Purchaser's proposed method of distribution of Registrable Securities and was reviewed
and expressly approved in writing by the Purchaser expressly for use in the Registration Statement, such Prospectus or such form
of Prospectus or in any amendment or supplement thereto or (ii) in the case of an occurrence of an event of the type specified
in Section 1.2(c)(v)-(vii), the use by the Purchaser of an outdated or defective Prospectus after Digital has notified the Purchaser
in writing that the Prospectus is outdated or defective and prior to the receipt by the Purchaser of the Advice contemplated in
Section 1.5. In no event shall the liability of any selling Purchaser hereunder be greater in amount than the dollar amount of
the net proceeds received by the Purchaser upon the sale of the Registrable Securities giving rise to such indemnification obligation.

 

    	B-4

    	 

    

 

(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 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 proximately and materially 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: (i) the Indemnifying Party has
agreed in writing to pay such fees and expenses; or (ii) 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 (iii) the
named parties to any such Proceeding (including any impleaded parties) include both such Indemnified Party and the Indemnifying
Party, and such Indemnified Party shall have been advised by counsel that a 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 such 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. 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.

 

All 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 1.4) shall be paid to the Indemnified Party, as incurred,
within ten Trading Days of written notice thereof to the Indemnifying Party (regardless of whether it is ultimately determined
that an Indemnified Party is not entitled to indemnification hereunder; provided, that the Indemnifying Party may require such
Indemnified Party to undertake to reimburse all such fees and expenses to the extent it is finally judicially determined that such
Indemnified Party is not entitled to indemnification hereunder).

 

(d) Contribution.
If a claim for indemnification under Section 1.4(a) or (b) is unavailable to an Indemnified Party (by reason of public policy or
otherwise), then each Indemnifying Party, in lieu of indemnifying such Indemnified Party, shall contribute to the amount paid or
payable by such Indemnified Party as a result of such Losses, 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 Section 1.4(c), any reasonable attorneys' or other reasonable 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 1.4 was available to such party in accordance with its terms.

 

    	B-5

    	 

    

 

The parties hereto
agree that it would not be just and equitable if contribution pursuant to this Section 1.4(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 1.4(d), no Purchaser shall be required to contribute, in the
aggregate, any amount in excess of the amount by which the net proceeds actually received by the Purchaser from the sale of the
Registrable Securities subject to the Proceeding exceeds the amount of any damages that the Purchaser has otherwise been required
to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. No Person guilty of fraudulent misrepresentation
(within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any Person who was not guilty
of such fraudulent misrepresentation.

 

The indemnity and contribution
agreements contained in this Section 1.4 are in addition to any liability that the Indemnifying Parties may have to the Indemnified
Parties.

 

1.5 Dispositions.

 

Each Purchaser agrees
that it will comply with the prospectus delivery requirements of the Securities Act as applicable to it in connection with sales
of Registrable Securities pursuant to the Registration Statement. Each Purchaser further agrees that, upon receipt of a notice
from Digital of the occurrence of any event of the kind described in Sections 1.2(c)(v), (vi) or (vii), the Purchaser will discontinue
disposition of such Registrable Securities under the Registration Statement until the Purchaser's receipt of the copies of the
supplemented Prospectus and/or amended Registration Statement contemplated by Section 1.2(j), or until it is advised in writing
(the "Advice") by Digital that the use of the applicable Prospectus may be resumed, and, in either case, has received
copies of any additional or supplemental filings that are incorporated or deemed to be incorporated by reference in such Prospectus
or Registration Statement. Digital may provide appropriate stop orders to enforce the provisions of this paragraph.

 

1.6 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 Digital
shall determine to prepare and file with the SEC 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 stock option or other employee benefit plans, then Digital
shall send to the Purchaser written notice of such determination and if, within fifteen days after receipt of such notice, the
Purchaser shall so request in writing, Digital shall include in such registration statement all or any part of the Registrable
Securities the Purchaser requests to be registered.
