SUPPORT AGREEMENT, dated as of March __, 2015 (this “Agreement”), between RMG
Networks Holding Corporation, a Delaware corporation (the “Company”) and the
stockholder set forth on the signature page hereto (the “Holder”).

WHEREAS, the Holder beneficially owns (or on the record date of the Special
Meeting (as defined below) will beneficially own), directly or indirectly,
shares of common stock, par value $0.0001 per share (the “Shares”), of the
Company (the “Common Stock”);

WHEREAS, the Company proposes to conduct a private placement of its Series A
Convertible Preferred Stock (the “Offering”), pursuant to a Purchase Agreement
of even date herewith (the “Purchase Agreement”) among the Company and the
investors named therein, including certain members of the Company’s management
(or their affiliates) (collectively, the “Investors”);

WHEREAS, pursuant to the terms of the Purchase Agreement, the Company intends to
call and hold a meeting of its stockholders (the “Special Meeting”) to seek
stockholder approval of the issuance and sale of shares of Common Stock to the
Investors pursuant to the Offering, to the extent required by the Nasdaq
Marketplace Rules, including (i) the issuance of shares of Common Stock in the
Offering, at a price less than the greater of market price or book value of such
securities, equaling 20% or more of the common stock or voting power of the
Company outstanding before the Offering, as and to the extent required by Nasdaq
Marketplace Rule 5635(d), (ii) the issuance of shares of Common Stock in the
Offering to officers or directors of the Company (or their affiliates), as and
to the extent required by Nasdaq Marketplace Rule 5635(c), and (iii) the
issuance of shares of Common Stock in the Offering in a manner that constitutes
a change of control of the Company, as and to the extent required by Nasdaq
Marketplace Rule 5635(b) (collectively, the “Proposal”); and

WHEREAS, the convertibility of the securities issued in the Offering is
contingent upon the receipt of approval of the Company’s stockholders of the
Proposal at the Special Meeting.

NOW, THEREFORE, in consideration of the foregoing, and intending to be legally
bound hereby, the parties hereto hereby agree as follows:

1.

Agreement to Vote

(a)

The Holder hereby agrees to vote (or cause to be voted), in person or by proxy,
at the Special Meeting all of the Shares beneficially owned by him, her or it as
of the record date for the Special Meeting (i) in favor of the approval of the
Proposal and (ii) without limitation of the preceding clause (i), in favor of
any proposal to adjourn or postpone the Special Meeting to a later date if there
are not sufficient votes for approval of such matters on the date on which the
Special Meeting is held.  Any such vote will be cast or consent will be given in
accordance with the procedures applicable thereto so as to ensure that it is
duly counted for purposes of determining that a quorum is present and for
purposes of recording the results of such vote or consent.  

(b)

The Holder hereby revokes (or causes to be revoked) any and all previous voting
proxies granted with respect to the voting of any of the Shares.

2.

Representations and Warranties and Covenants of the Holder.  The Holder hereby
represents and warrants, severally but not jointly, to the Company and each
Investor as follows:

(a)

The Holder has full requisite authority and power to execute, deliver and
perform its obligations under this Agreement.  The execution of this Agreement
and the consummation of the transactions contemplated hereby have been duly and
validly authorized by all required action on the part of the Holder and no other
proceedings on the part of the Holder are necessary to authorize this Agreement
and the consummation of the transactions contemplated hereby.  This Agreement
constitutes a legal, valid and binding obligation of the Holder, enforceable
against the Holder in accordance with its terms, except (a) as such
enforceability may be limited by applicable bankruptcy, insolvency,
reorganization, fraudulent conveyance, moratorium or similar laws now or
hereafter in effect relating to, or affecting generally the enforcement of
creditors’ and other obligees’ rights, (b) where the remedy of specific
performance or other forms of equitable relief may be subject to certain
equitable defenses and principles and to the discretion of the court before
which the proceeding may be brought, and (c) where rights to indemnity and
contribution thereunder may be limited by applicable law and public policy.

--------------------------------------------------------------------------------

(b)

The execution and delivery of this Agreement by the Holder does not, and the
performance of this Agreement by the Holder shall not, (i) conflict with or
violate any federal, state or local law, statute, ordinance, rule, regulation,
order, judgment or decree applicable to the Holder or by which the Shares owned
by the Holder are bound or affected or (ii) result in any breach of or
constitute a default (or an event that with notice or lapse of time or both
would become a default) under, or give to others any rights of termination,
amendment, acceleration or cancellation of, or result in the creation of a lien
or encumbrance on any of the Shares owned by the Holder pursuant to, any note,
bond, mortgage, indenture, contract, agreement, lease, license, permit,
franchise or other instrument or obligation to which the Holder is a party or by
which the Holder or the Shares owned by the Holder are bound.

(c)

The execution and delivery of this Agreement by the Holder does not, and the
performance of this Agreement by the Holder shall not, require any consent,
approval, authorization or permit of, or filing with or notification to, any
governmental entity by the Holder (except for filing pursuant to the Securities
Exchange Act of 1934, as amended).

(d)

The Holder holds, beneficially or of record, good and valid title to the Shares
owned by the Holder and has the power to vote, without restriction, such Shares
on all matters brought before holders of capital stock of the Company.  The
Holder has not appointed or granted any proxy, which appointment or grant is
still effective, with respect to the Shares owned by the Holder.

(e)

The Holder hereby covenants and agrees that the Holder shall not, until the
termination of this Agreement, offer or agree to sell, transfer, tender, assign,
hypothecate or otherwise dispose of its securities, grant a proxy or power of
attorney with respect to, or create or permit to exist any limitation on the
Holder’s voting rights (“Encumbrance”) with respect to its Shares, directly or
indirectly, initiate, solicit or encourage any person to take actions which
could reasonably be expected to lead to the occurrence of any of the foregoing;
provided, however, that any the Holder may assign, sell, transfer, tender,
hypothecate or otherwise dispose of any Shares owned by it provided that any
such recipient of such Shares has delivered to the Company and each Investor a
written agreement in a form reasonably satisfactory to the Investors that the
recipient shall be bound by, and the Shares so transferred, assigned or sold
shall remain subject to this Agreement.

3.

Termination.  This Agreement and the obligations of the parties under this
Agreement may only be terminated upon the mutual consent of all parties hereto;
provided, however, that this Agreement shall automatically terminate, without
any action by the parties hereto, upon the first to occur of (a) the approval by
the Company’s stockholders of the Proposal, (b) the conclusion of the last
Subsequent Stockholders Meeting (as such term is defined in the Purchase
Agreement) or (c) the termination of the Purchase Agreement in accordance with
its terms.

4.

Miscellaneous.  

(a)

Except as otherwise provided herein or in the Purchase Agreement, all costs and
expenses incurred in connection with this Agreement and the transactions
contemplated hereby shall be paid by the party incurring such costs and
expenses, whether or not the transactions contemplated hereby are consummated.

(b)

All notices, requests, claims, demands and other communications under this
Agreement shall be in writing and shall be deemed given if delivered personally,

internationally recognized overnight courier (providing proof of delivery), or
mailed in the United States by certified or registered mail, postage prepaid, to
the parties at the following addresses (or at such other address for a party as
shall be specified by like notice):

(c)

If any term or other provision of this Agreement is held to be invalid, illegal
or incapable of being enforced by any rule of law or public policy by a court of
competent jurisdiction, all other conditions and provisions of this Agreement
shall nevertheless remain in full force and effect, insofar as the foregoing can
be accomplished without materially affecting the economic benefits anticipated
by the parties to this Agreement.  Upon such determination that any term or
other provision is invalid, illegal or incapable of being enforced, the parties
hereto shall negotiate in good faith to modify this Agreement so as to effect
the original intent of the parties as closely as possible to the fullest extent
permitted by applicable law in an acceptable manner to the end that the
transactions contemplated by this Agreement are fulfilled to the extent
possible.

--------------------------------------------------------------------------------

(d)

This Agreement constitutes the entire agreement, and supersedes all prior
agreements and understandings, both written and oral, among the parties with
respect to the subject matter of this Agreement and is not intended to and shall
not confer upon any person other than the parties hereto any rights or remedies
hereunder.

(e)

This Agreement may be executed in counterparts, each of which when executed
shall be deemed to be an original, and all of which together will be considered
one and the same agreement and shall become effective when one or more
counterparts have been signed by each of the parties and delivered to the other
parties.  For purposes of this Agreement, facsimile signatures or signatures by
other electronic form of delivery shall be deemed originals.

(f)

This Agreement and any claim, controversy or dispute arising under or related
thereto, the relationship of the parties, and/or the interpretation and
enforcement of the rights and duties of the parties, whether arising in law or
in equity, in contract, tort or otherwise, shall be governed by, and construed
and interpreted in accordance with, the laws of the State of Delaware, without
regard to its rules regarding conflicts of law to the extent that the
application of the laws of another jurisdiction would be required thereby.

(g)

Neither this Agreement nor any of the rights, interests or obligations under
this Agreement shall be assigned, in whole or in part, by operation of law or
otherwise by either of the parties hereto without the prior written consent of
the other party, except as provided in Section 2 hereof.  Any assignment in
violation of the preceding sentence shall be void.  Subject to the preceding two
sentences, this Agreement will be binding upon, inure to the benefit of, and be
enforceable by, the parties and their respective successors and assigns.

(h)

Each of the parties hereto hereby irrevocably agrees that any legal action or
proceeding with respect to this Agreement, or for recognition and enforcement of
any judgment in respect of this Agreement and obligations arising hereunder
brought by any party hereto or its successors or assigns, shall be brought and
determined exclusively in the Delaware Court of Chancery and any state appellate
court therefrom within the State of Delaware (or, if the Delaware Court of
Chancery declines to accept jurisdiction over a particular matter, any state or
federal court within the State of Delaware).  Each of the parties hereto hereby
irrevocably submits with regard to any such action for itself and in respect of
its property, generally and unconditionally, to the personal jurisdiction of the
aforesaid courts and agrees that it will not bring any action relating to this
Agreement in any court other than the aforesaid courts.  Each of the parties
hereto hereby irrevocably waives, and agrees not to assert, by way of motion, as
a defense, counterclaim or otherwise, in any action or proceeding with respect
to this Agreement, (a) any claim that it is not personally subject to the
jurisdiction of the above-named courts for any reason other than the failure to
serve in accordance with this Section 4(h), (b) any claim that it or its
property is exempt or immune from jurisdiction of any such court or from any
legal process commenced in such courts (whether through service of notice,
attachment prior to judgment, attachment in aid of execution of judgment,
execution of judgment or otherwise) and (c) to the fullest extent permitted by
the applicable law, any claim that (i) the action in such court is brought in an
inconvenient forum, (ii) the venue of such action is improper or (iii) this
Agreement or the subject matter hereof may not be enforced in or by such courts.

(i)

Subject to applicable law, any provision of this Agreement may be waived.  Any
agreement on the part of a party to any such waiver shall be valid only if set
forth in an instrument in writing signed on behalf of the party against whom
waiver is sought; provided, that any waiver given in compliance with this
Section 4(i) or failure to insist on strict compliance with an obligation,
covenant, agreement or condition shall not operate as a waiver of, or estoppel
with respect to, any subsequent or other failure.  Subject to applicable law,
any of the provisions of this Agreement may be amended at any time, by the
mutual written agreement of the parties.  No failure or delay on the part of any
party hereto in the exercise of any right hereunder shall impair such right or
be construed to be a waiver of, or acquiescence in, any breach of any
representation, warranty or agreement herein, nor shall any single or partial
exercise of any such right preclude any other or further exercise thereof or of
any other right.

(j)

EACH OF THE PARTIES HERETO HEREBY IRREVOCABLY WAIVES ALL RIGHT TO TRIAL BY JURY
IN ANY ACTION OR COUNTERCLAIM (WHETHER BASED ON CONTRACT, TORT OR OTHERWISE)
ARISING OUT OF OR RELATING TO THIS AGREEMENT OR THE ACTIONS OF THE PARTIES IN
THE NEGOTIATION, ADMINISTRATION, PERFORMANCE AND ENFORCEMENT OF THIS AGREEMENT.

(k)

The parties agree that irreparable damage would occur and that the parties would
not have any adequate remedy at law in the event that any of the provisions of
this Agreement were not performed in accordance with their specific terms or
were otherwise breached by any party.  It is accordingly agreed that the parties
shall be entitled to an injunction or injunctions to prevent breaches and/or
threatened breaches of this Agreement and to enforce specifically the terms and
provisions of this Agreement in any federal court located in the State of
Delaware or in Delaware state court, this being in addition to any other remedy
to which they are entitled to at law or in equity.
