RIGHTS OFFERINGS

by a special committee of the Non-Affiliated Directors or a subset thereof as a Related Party Transaction pursuant to Section 7.1(b)(ii),

terms as the backstop in connection with the Initial Rights Offering. The procedures for taking subscriptions and allocating shares
in any Follow On Rights Offering shall be substantially the same as the procedures used in the Initial Rights Offering; provided

Section 4.3

(a)               
If the Company proposes to undertake a Rights Offering with one or more Backstop Agents, it shall
give written notice to the Stockholder of its intention to undertake the Rights Offering (the “Rights Offering Notice”),
describing the price and the terms upon which the Company proposes to offer New Securities in the Rights Offering and the terms
on which the Company proposes to engage a Backstop Agent(s) for the Rights Offering. The Stockholder (or its designee) shall have
15 days from receipt of any such Rights Offering Notice to agree to serve as the Backstop Agent for the Rights Offering upon the
terms specified in the Rights Offering Notice by giving written notice to the Company and stating in such notice the portion of
the Rights Offering for which the Stockholder will serve as Backstop Agent.

(b)              
 If the Stockholder (or its designee) fails to provide such written notice within such 15
day period or provides written notice that it elects not to serve as Backstop Agent for all or any portion of the Rights Offering,
then the Company shall have 90 days from the expiration of the period set forth above to engage other Backstop Agents as to any
portion of the Rights Offering to which the Stockholder has not agreed to serve as Backstop Agent and to consummate the Rights
Offering, in each case, upon terms not materially more favorable to the other Backstop Agents and the stockholders of the Company
than specified in the Rights Offering Notice. If the Company has not consummated the Rights Offering within such period, then after
such period the Company shall not commence any Rights Offering without again first complying with this  ARTICLE
IV.

(c)               
If the Stockholder (or its designee) provides written notice within such 15 day period that it
elects to serve as Backstop Agent for all or any portion of the Rights Offering, then the Company and the Stockholder (or its designee)
shall promptly thereafter execute and deliver a customary engagement letter providing for the terms on which the Stockholder (or
its designee) will serve as Backstop Agent. The Company and the Board shall also take all necessary action, if any, in order to
render inapplicable any control share acquisition, business combination, poison pill (including any distribution under the Rights
Agreement or any other rights agreement) or other similar anti-takeover provision under the Company’s charter, bylaws or
similar charter documents or the laws of its state of incorporation that is or could become applicable to the Company as a result
of the Company and the Stockholder (or its designee) consummating any such Rights Offering (including the issuance of any New Securities
by the Company to the Stockholder (or its designee) in connection with any such Rights Offering). Any such engagement shall be
subject to compliance with applicable federal and state securities laws.

make the Stockholder’s and its Affiliates’ network of financial industry contacts and counterparties available
to assist the Company in securing debt funding on attractive terms, attracting equity research coverage and engaging in other matters
of similar nature;

(d)              
support the Company’s syndication efforts to the extent commercially reasonable, and in any event, make referrals
to other investors on behalf of the Company and grant supporting references to the Company and its management;

(e)               
be available as a syndication partner to the Company, if (i) the Company has had priority with respect to any allocation
relating to such syndication, (ii) the Stockholder participates on terms (x) no worse than those of the Company’s participation
and (y) no better than those of any other syndication partner, (iii) the Stockholder determines in its sole discretion that the
syndication is attractive and within the Stockholder’s investment mandate and (iv) to the extent not inconsistent with the
requirements in clauses (i) – (iii), such syndication is subject to the investment management agreement by and between the
Stockholder and SWK Advisors LLC; and

(f)               
explore the establishment of an equal joint venture between an Affiliate of the Stockholder and the Company pursuant to
which the Company would become the asset manager of a new fund under the “Black Diamond” brand (a “Sponsored
Fund”). The ultimate determination to participate in any such joint venture would be made in the Stockholder’s
sole discretion. Any joint venture would be subject to the Company (i) fully investing its available financial resources, including
prudent leverage, and (ii) establishing a track record sufficient to attract outside investors in a fund format. The Stockholder’s
responsibility would include fundraising, regulatory compliance, establishment of entity structuring, fund documentation and a
“seed” investment. The Company would be responsible for sourcing, closing and monitoring transactions.

Section 5.2           
Stockholder Support Services. The obligations set forth in Section 5.1 are collectively referred to as the “Stockholder
Support Services.” For the avoidance of doubt, any Stockholder Support Service that constitutes or results in a Related
Party Transaction shall be subject to approval by a special committee of the Non-Affiliated Directors or a subset thereof as a
Related Party Transaction pursuant to Section 7.1(b)(ii). In addition, the terms of any Stockholder Support Service that constitutes
or results in a Related Party Transaction shall be disclosed to the holders of the Common Stock. Disclosure in a public filing

MISCELLANEOUS

Section 10.1       
Injunctive Relief. Each party hereto acknowledges that it would be impossible to determine the amount of damages
that would result from any breach of any of the provisions of this Agreement and that the remedy at law for any breach, or threatened
breach, of any of such provisions would likely be inadequate and, accordingly, agrees that the other party shall, in addition to
any other rights or remedies which it may have, be entitled to such equitable and injunctive relief as may be available from any
court of competent jurisdiction to compel specific performance of, or restrain any party from violating, any of such provisions.
In connection with any action or proceeding for injunctive relief, each party hereto hereby waives the claim or defense that a
remedy at law alone is adequate and agrees, to the maximum extent permitted by Law, to have each provision of this Agreement specifically
enforced against it, without the necessity of posting bond or other security against it, and consents to the entry of injunctive
relief against it enjoining or restraining any breach or threatened breach of such provisions of this Agreement.

the other party other than (a) in connection with a change in control of the Stockholder or to any successor of the Company
or (b) by the Stockholder in whole or in part, to one or more of its Affiliates so long as the Stockholder remains liable
for its obligations as contained herein. Any purported direct or indirect assignment in violation of this Section 10.2 shall be
null and void ab initio.

Section 10.3       
Amendments; Waiver. No amendment, modification or discharge of this Agreement, and no waiver hereunder, and no extension

executed by (a) the Company where enforcement of the amendment, modification, discharge, waiver or extension is sought against
the Company or (b) the Stockholder where enforcement of the amendment, modification, discharge, waiver or extension is sought
against the Stockholder. Any such waiver shall constitute a waiver only with respect to the specific matter described in such writing
and shall in no way impair the rights of the party granting such waiver in any other respect or at any other time. The waiver by
the Company or the Stockholder of a breach of, or a default under, any of the provisions hereof, or to exercise any right or privilege
hereunder, shall not be construed as a waiver of any other breach or default of a similar nature, or as a waiver of any of such
provisions, rights or privileges hereunder. Except as expressly provided in this Agreement, the rights and remedies herein provided
are cumulative and none is exclusive of any other, or of any rights or remedies that any party may otherwise have at law or in
equity.

Recapitalization, Etc. In the event that any capital stock or other securities are issued in respect of, in exchange
for, or in substitution of, shares of capital stock of the Company by reason of any reorganization, recapitalization, reclassification,
merger, consolidation, spin-off, partial or complete liquidation, stock dividend, split-up, sale of assets, distribution to stockholders
or combination of shares or any other change in the Company’s capital structure, appropriate adjustments shall be made to
the provisions of this Agreement so as to fairly and equitably preserve, as far as practicable, the original rights and obligations
of the parties hereto under this Agreement.

Section 10.6       
Further Action. From time to time after the Closing Date, without additional consideration, each party hereto will
(or, if appropriate, will cause its Subsidiaries to) execute and deliver such further instruments and take such other action as
may be necessary or reasonably requested by another party hereto to make effective the transactions contemplated hereby. Without
limiting the foregoing, the Company will, in order to permit the Stockholder and its Affiliates to acquire additional shares of
Common Stock to increase their Voting Percentage to 76%, cause the Rights Agreement to be amended to allow the Stockholder and
its Affiliates to increase their Voting Percentage to such amount. Notwithstanding the foregoing, in no event shall the Company
or its Subsidiaries be required to take any action that would be reasonably likely to jeopardize the Company’s ability to
retain the benefit of the NOLs.
