RECITALS

 

A.           MAM
Software Group, Inc., a Delaware corporation (the “Borrower”), and the Lender are parties to a Credit Agreement
dated as of even date herewith (as amended, restated, modified, substituted, extended and renewed from time to time, the “Credit
Agreement”) under which, among other things, the Lender has agreed, subject to the terms and conditions of the Credit

B.           All
defined terms used in this Agreement and not defined herein shall have the meaning given to such terms in the Credit Agreement.

Guarantor has requested that the Lender enter into the Credit Agreement with the Borrower and make the credit facilities described

NOW, THEREFORE, in order
to induce the Lender to enter into the Credit Agreement, the Guarantor covenants and agrees with the Lender as follows:

 

ARTICLE

THE
GUARANTY

 

Section 1.1           Guaranty.

 

The Guarantor hereby unconditionally
and irrevocably guarantees to the Lender:

 

(a)          the
due and punctual payment in full (and not merely the collectibility) of the principal of the Secured Obligations and the interest
thereon, in each case when due and payable, all according to the terms of any promissory note evidencing all or any part of the
Secured Obligations and the other Loan Documents (as that term is defined in the Credit Agreement);

 

(b)          the
due and punctual payment in full (and not merely the collectibility) of all other sums and charges which may at any time be due
and payable in accordance with, or secured by, any promissory note evidencing all or any part of the Secured Obligations or any
of the other Loan Documents;

 

(c)          the
due and punctual performance of all of the other terms, covenants and conditions contained in the Loan Documents; and

 

    	 	1	 

     

    

  

(d)          all
indebtedness, obligations and liabilities of any kind and nature of the Borrower to the Lender, whether now existing or hereafter
created or arising, direct or indirect, matured or unmatured, and whether absolute or contingent, joint, several or joint and several,
and howsoever owned, held or acquired arising under the Loan Documents;

 

provided, however,
that if and only if the Guarantor is not an “eligible contract participant” (as defined in the Commodity Exchange Act
and any applicable rules, as amended), then to the extent applicable law prohibits the Guarantor from entering into an agreement
to guaranty any obligations in respect of a “swap” (as defined in the Commodity Exchange Act and any applicable rules,
as amended, and referred to herein as a “Swap”), the term “Secured Obligations” shall not include, and
this Agreement shall not cover, indebtedness, liabilities, or obligations of the Borrower to the Lender under any Swap.

 

Section 1.2           Guaranty
Unconditional.

 

Subject to the terms of
the Credit Agreement, the obligations and liabilities of the Guarantor under this Agreement shall be absolute and unconditional,
irrespective of the genuineness, validity, priority, regularity or enforceability of the Credit Agreement, any promissory note
evidencing all or any part of the Secured Obligations, or any of the other Loan Documents or any other circumstance which might
otherwise constitute a legal or equitable discharge of a surety or guarantor. The Guarantor expressly agrees that the Lender may,
in its sole and absolute discretion, without notice to or further assent of the Guarantor and without in any way releasing, affecting
or in any way impairing the obligations and liabilities of the Guarantor hereunder:

 

(a)          waive
compliance with, or any defaults under, or grant any other indulgences under or with respect to any of the Loan Documents;

 

(b)          modify,
amend, change or terminate any provisions of any of the Loan Documents;

 

(c)          grant
extensions or renewals of or with respect to any promissory note evidencing all or any part of the Secured Obligations, any of
the other Loan Documents or any of the Secured Obligations;

 

(d)          effect
any release, subordination, compromise or settlement in connection with any promissory note evidencing all or any part of the Secured
Obligations, any of the other Loan Documents, or any of the Secured Obligations;

 

(e)          agree
to the substitution, exchange, release or other disposition of the Collateral or any part thereof, or any other collateral for
the Secured Obligations or to the subordination of any lien or security interest therein;

 

(f)           make
advances for the purpose of performing any term, provision or covenant contained in the Credit Agreement or any of the other Loan
Documents with respect to which the Borrower shall then be in default;

 

(g)          make
future advances to the Borrower pursuant to the Credit Agreement or any of the other Loan Documents;

 

(h)          assign,
pledge, hypothecate or otherwise transfer the Credit Agreement, any of the Loan Documents or this Agreement or any interest therein;

 

    	 	2	 

     

    

 

(i)           deal
in all respects with the Borrower as if this Agreement were not in effect; and

  

(j)           effect
any release, compromise or settlement with another guarantor.

 

Section 1.3           Guaranty
Primary.

 

The obligations and liabilities
of the Guarantor under this Agreement shall be primary, direct and immediate, shall not be subject to any counterclaim, recoupment,
setoff, reduction or defense based upon any claim that the Guarantor may have against the Borrower, the Lender and/or any other
guarantor and shall not be conditional or contingent upon pursuit or enforcement by the Lender of any remedies it may have against
the Borrower with respect to any promissory note evidencing all or any part of the Secured Obligations or any of the other Loan
Documents, whether pursuant to the terms thereof or by operation of law. Without limiting the generality of the foregoing, the
Lender shall not be required to make any demand upon the Borrower, or to sell the Collateral or otherwise pursue, enforce or exhaust
its remedies against the Borrower or the Collateral either before, concurrently with or after pursuing or enforcing its rights
and remedies hereunder. Any one or more successive or concurrent actions or proceedings may be brought against the Guarantor under
this Agreement, either in the same action, if any, brought against the Borrower or in separate actions or proceedings, as often
as the Lender may deem expedient or advisable. Without limiting the foregoing, it is specifically understood that any modification,
limitation or discharge of any of the liabilities or obligations of the Borrower, any other guarantor or any obligor under any
of the Loan Documents, arising out of, or by virtue of, any bankruptcy, arrangement, reorganization or similar proceeding for relief
of debtors under federal or state law initiated by or against the Borrower or the Guarantor or any obligor under any of the Loan
Documents shall not modify, limit, lessen, reduce, impair, discharge, or otherwise affect the liability of the Guarantor hereunder
in any manner whatsoever, and this Agreement shall remain and continue in full force and effect. It is the intent and purpose of
this Agreement that the Guarantor shall and does hereby waive all rights and benefits which might accrue to any other guarantor
by reason of any such proceeding, and the Guarantor agrees that it shall be liable for the full amount of the obligations and liabilities
under this Agreement, regardless of, and irrespective to, any modification, limitation or discharge of the liability of the Borrower,
any other guarantor or any obligor under any of the Loan Documents, that may result from any such proceedings.

 

Section 1.4           Certain
Waivers by the Guarantor.

 

The Guarantor hereby unconditionally,
irrevocably and expressly waives:

(b)          notice

and

other notices and demands otherwise required by law which the Guarantor may lawfully waive.

the Post-Default Rate.

of Default.

 

Subject to the terms of
the Credit Agreement, without implying any limitation of the Lender’s right to immediate payment at any time of any Secured

or (vi) by any act indicate its consent to, approval of or acquiescence in any such proceeding or the appointment of any receiver

(g)          Unless
adequately insured in the opinion of the Lender, the entry of a final judgment for the payment of money involving more than $100,000

    	 	5	 

     

    

  

Section 1.8           Subordination;
Subrogation.

 

Subject to the terms and
condition of the Credit Agreement, in the event the Guarantor shall advance any sums to the Borrower, or in the event the Borrower
has heretofore or shall hereafter become indebted to the Guarantor before the Secured Obligations have been paid in full, all such
advances and indebtedness shall be subordinate in all respects to the Secured Obligations (the “Guarantor Subordinated Debt”).
Any payment to the Guarantor on account of the Guarantor Subordinated Debt shall be collected and received by the Lender or the
Guarantor in trust for the Lender and shall be paid over to the Lender on account of the Secured Obligations without impairing
or releasing the obligations of the Guarantor hereunder.

 

Without the prior written
consent of the Lender, the Guarantor shall not ask, demand, receive, accept, sue for, set off, collect or enforce the Guarantor
Subordinated Debt or any collateral and security therefor. The Guarantor represents and warrants to the Lender that the Guarantor
Subordinated Debt is unsecured and agrees not to receive or accept any collateral or security therefor without the prior written
permission of the Lender. The Guarantor shall not assign, transfer, hypothecate or dispose of the Guarantor Subordinated Debt while
this Agreement is in effect. In the event of any sale, receivership, insolvency or bankruptcy proceeding, or assignment for the
benefit of creditors, or any proceeding by or against the Borrower for any relief under any bankruptcy or insolvency law or other
laws relating to the relief of debtors, readjustment of indebtedness, reorganizations, compositions or extensions, then and in
any such event any payment or distribution of any kind or character, either in cash, securities or other property, which shall
be payable or deliverable upon, or with respect to, all or any part of the Guarantor Subordinated Debt or otherwise shall be paid
or delivered directly to the Lender for application to the obligations and liabilities of the Guarantor under this Agreement (whether
due or not due and in such order and manner as the Lender may determine in the exercise of its sole discretion) until the obligations
of the Guarantor hereunder shall have been fully paid and satisfied. The Guarantor hereby irrevocably authorizes and empowers the
Lender to demand, sue for, collect and receive every such payment or distribution on account of the Guarantor Subordinated Debt
and give acquittance therefor and to file claims and take such other proceedings in the Lender’s own name or in the name
of the Guarantor or otherwise, as the Lender may deem necessary or advisable to carry out the provisions of this Agreement. The
Guarantor hereby agrees to execute and deliver to the Lender such powers of attorney, assignments, endorsements or other instruments
as may be requested by the Lender in order to enable the Lender to enforce any and all claims upon, or with respect to, the Guarantor
Subordinated Debt, and to collect and receive any and all payments or distributions which may be payable or deliverable at any
time upon or with respect thereto.

 

So as to secure the performance
by the Guarantor of the provisions of this Agreement, the Guarantor assigns, pledges and grants to the Lender a security interest
in, and lien on, the Guarantor Subordinated Debt, all proceeds thereof and all and any security and collateral therefor. Upon the
request of the Lender, the Guarantor shall endorse, assign and deliver to the Lender all notes, instruments and agreements evidencing,
securing, guarantying or made in connection with the Guarantor Subordinated Debt.

 

Nothing contained in this
Agreement shall be construed to give the Guarantor any right of subrogation in or to the Secured Obligations or any of the Loan
Documents, or all or any part of the interest of the Lender therein, until the Secured Obligations have been paid in full.
