the Effective Time in exchange for a purchase price equal to, for 

  
 12. 

 
each $1,000 principal amount of Convertible Notes so sold, an amount equal to the Conversion Rate (as defined in the Indenture) on the Conversion Date (as defined in the Indenture) (and shall be
increased pursuant to Section 10.14 of the Indenture in respect of the transactions contemplated by the Merger Agreement as if such Convertible Notes had been converted during the Make-Whole Conversion Period (as defined in the Indenture)
relating to the Merger), multiplied by the price paid per share of Common Stock in the Merger pursuant to the Merger Agreement (i.e., the Merger Consideration), plus all unpaid interest accrued on such Convertible Notes to, but excluding, such date,
which purchase price shall be payable in cash to the Securityholder on the Closing Date (such date of payment, the “Payment Date”). For purposes of the foregoing calculation of the purchase price and for the avoidance of doubt, the
parties agree that the Merger shall constitute a Make-Whole Fundamental Change under the Indenture. Securityholder and the Company agree that, in the event the Payment Date for such repurchase occurs after a record date for payment of interest with
respect to the Convertible Notes so repurchased but on or before the related scheduled interest payment date provided for under the Indenture, the Company shall pay accrued and unpaid interest on the Convertible Notes so repurchased in accordance

Securities (as defined in the Indenture) shall automatically be converted in accordance with the Indenture, which, for the avoidance of doubt, shall entitle holders of the SL Securities (as defined in the Indenture) to receive as consideration for
such conversion cash in an amount as provided by Section 10.11 of the Indenture giving effect to the Merger at the then applicable Conversion Rate, increased pursuant to Section 10.14 of the Indenture in respect of the Merger (the
“Automatic Conversion”), 
 (2) the consideration for the Automatic Conversion shall be paid to the holders of the SL
Securities on the Closing Date, and 
 (3) SL Securities cannot be exchanged for, and beneficial interests in Global Securities (as defined
in the Indenture) that are SL Securities cannot be exchanged for, Securities that are not SL Securities and that SL Securities need not be held, and beneficial interests in Global Securities (as defined in the Indenture) that are SL Securities need
not be held, by Persons (as defined in the Indenture) who are Purchasers (as defined in the Indenture) or Affiliates (as defined in the Indenture) of Purchasers, and provide that the transfer and exchange provisions and forms contained in the
Indenture shall be modified accordingly, and 
 (4) upon conversion of the Convertible Notes on the Closing Date pursuant to an Automatic
Conversion, the Company will pay to each converting holder of Convertible Notes accrued but unpaid interest on such Convertible Notes to, but excluding, the Closing Date, and that, in connection with such conversion, the last sentence of
Section 10.02(d) of the Indenture will not apply, and 
 (B) add at the end of Section 4.07 of the Indenture the following words,

 13. 

 
Holdings, Inc. (“Parent”), Sunshine Software Merger Sub, Inc. (“Merger Sub”) and the Company (as it may be amended from time to time, the “Merger Agreement”)) and
shall not restrict any further incurrence of Indebtedness from time to time in such amounts as determined by the Company, provided that (x) such Closing occurs prior to the date that is five (5) business days following February 5,

Merger Agreement) for payment of the Merger Consideration (as defined in the Merger Agreement) at a price per share of Common Stock (as adjusted for stock splits, stock dividends, reverse stock splits and combinations) converted into the right to
receive the Merger Consideration that is not less than the price per share of Common Stock provided in the Merger Agreement as of August 5, 2021, to repay outstanding Indebtedness of the Company and its Subsidiaries to the extent required by
the Merger Agreement, and to pay in full on the date of Closing the consideration due upon conversion or repurchase of the SL Securities in connection with the Merger (as defined in the Merger Agreement) (which consideration due shall be (I) in
the case of a conversion, the amount described in Section 5.25(b)(A)(1) and (A)(4) of each of the Support Agreements, dated as of August 5, 2021 among Sunshine Software Holdings, Inc. Sunshine Software Merger Sub, Inc., the Company and,
respectively, SLA CM Chicago Holdings, L.P. and SLA Chicago Co-Invest II, L.P. (the “Support Agreements”) and (II) in the case of a repurchase, the amount described in Section 5.25(a) of
the Support Agreements (subject, as to timing, to the last sentence of such 5.25(a), as applicable)), and to pay expenses related to the transactions contemplated by the Merger Agreement to the extent required by the Merger Agreement.” 

Securityholder acknowledges that this Section 5.25(b) is intended to be (i) a consent contemplated by Article 9 of the
Indenture to each of the foregoing amendments described in clauses (A) and (B) above (each an “Indenture Amendment” and collectively, the “Indenture Amendments”) upon which the Company and the
Trustee (as defined in the Indenture) can conclusively rely in connection with effecting the Indenture Amendments and that the Company intends to (unless Parent otherwise requests in writing) effect both Indenture Amendments (the Indenture
Amendments so effected, the “applicable Indenture Amendments”) and (ii) irrevocable as long as this Agreement is in effect. Securityholder agrees to use reasonable best efforts to take all actions reasonably necessary on
its part to cause the applicable Indenture Amendments to be effective in a manner reasonably requested by Parent or the Company as promptly as practicable after the public announcement of the Merger Agreement and in any event no later than 25
business days after the date hereof, and to take all action required on its part, in the case of the distribution of a consent solicitation, to cause the submission of consents in accordance with the applicable procedures of the Depository (as
defined in the Indenture) promptly after the distribution thereof through the facilities of the Depository). Securityholder and the Company agree that (x) Section 4.14 of the Investment Agreement shall be of no further effect from and
after the date of this Agreement and (y) the Company shall execute a waiver of the covenant, agreement and acknowledgement of the lender(s) in Section 10 of the issuer agreement(s) between the Company and the lenders under the Financing
Agreement, effective from and after the date of this Agreement. 
 (c) Securityholder hereby agrees to take any and all actions to cause all of the
Affiliate Agreements to be terminated (without payment or other consideration or concession by Parent, the Company or any of their Subsidiaries except as otherwise provided herein or therein), effective as of and contingent upon the Closing and
payment of the consideration payable in respect of the Automatic Conversion, such that such agreements shall be of no further force or effect immediately thereafter, except for (i) any rights, obligations or other provisions that survive
termination of such agreements by their terms, (ii) unpaid expense reimbursement or other fees or compensation owed to Securityholder or its affiliates or representatives, including any director designee, (iii) any indemnification
provisions inuring to the benefit of Securityholder, its affiliates or representatives, including any director designee, in connection with Securityholder’s investment in the Company and (iv) to the extent that a party thereunder may seek
recourse for any breach thereof. 

  
 14. 

 (d) If the Closing occurs, this Section 5.25 shall survive any Expiration Date to
the extent necessary for performance of this Section 5.25 to be completed. 
 5.26. Registration Waiver. After the execution
of this Agreement and until termination of this Agreement in accordance with its terms, Securityholder, on behalf of itself and its affiliates, waives any requirement of the Company to register the Convertible Notes for resale and any event of
default in relation thereto. 
 5.27 Construction. 

(a) For purposes of this Agreement, whenever the context requires: the singular number shall include the plural, and vice versa; the masculine gender
shall include the feminine and neuter genders; the feminine gender shall include the masculine and neuter genders; and the neuter gender shall include masculine and feminine genders. 

(b) The parties have participated jointly in negotiating and drafting this Agreement. In the event that an ambiguity or a question of intent or
interpretation arises, this Agreement shall be construed as if drafted jointly by the parties, and no presumption or burden of proof shall arise favoring or disfavoring any party by virtue of the authorship of any provision of this Agreement. 

(c) As used in this Agreement, the words “include” and “including,” and variations thereof, shall not be deemed to be terms of
limitation, but rather shall be deemed to be followed by the words “without limitation.”

references in this Agreement to “Sections” and “Exhibits” are intended to refer to Sections of this Agreement and Exhibits to this Agreement, and the words “herein,” “hereof” and “hereunder,” and
words of similar import, shall be construed to refer to this Agreement in its entirety and not to any particular provision of this Agreement. The word “or” when used in this Agreement is not exclusive. The word “extent” in the
phrase “to the extent” shall mean the degree to which a subject or other thing extends, and such phrase shall not mean simply “if”. 

5.28 Termination. This Agreement shall terminate automatically upon the first to occur of (a) the termination of the Merger Agreement in accordance
with its terms, (b) the later of (i) the Effective Time and (ii) the performance by all parties of all obligations hereunder, (c) the date that is five (5) business days following February 5, 2022 and (d) the date
of any Adverse Amendment. An “Adverse Amendment” means an amendment or modification to the Merger Agreement or a document ancillary thereto, or a waiver of a provision therein, in a manner that (i) decreases the amount or
changes the kind of consideration to be paid to the Company’s stockholders in connection with the Merger, or (ii) increases the obligations or liabilities of Securityholder under this Agreement.

successors and Representatives hereby expressly and irrevocably waives, any breach by Securityholder of Section 4.18 of the Investment Agreement arising from, or relating to, Securityholder’s entry into, consummation of or performance of
its obligations under this Agreement.

 5.10 Severability. Any term or provision of this Agreement
that is invalid or unenforceable in any situation in any jurisdiction shall not affect the validity or enforceability of the remaining terms and provisions hereof or the validity or enforceability of the offending term or provision in any other
situation or in any other jurisdiction. If the final judgment of a court of competent jurisdiction declares that any term or provision hereof is invalid or unenforceable, the parties hereto agree that the court making such determination shall have
the power to limit the term or provision, to delete specific words or phrases, or to replace any invalid or unenforceable term or provision with a term or provision that is valid and enforceable and that comes closest to expressing the intention of
the invalid or unenforceable term or provision, and this Agreement shall be enforceable as so modified. In the event such court does not exercise the power granted to it in the prior sentence, the parties hereto agree to replace such invalid or
unenforceable term or provision with a valid and enforceable term or provision that will achieve, to the extent possible, the economic, business and other purposes of such invalid or unenforceable term or provision.

connection herewith constitute the entire agreement between the parties with respect to the subject matter hereof and thereof and supersede all prior agreements and understandings between the parties with respect thereto.

forth in this Agreement shall be construed as independent of any other Contract between such party, on the one hand, and the any of the other parties, on the other. The existence of any claim or cause of action by a party against another party shall

expressly stated otherwise herein, any of the rights or remedies or any of the obligations under any agreement between the parties or any certificate or instrument executed by a party in favor of another party, and nothing in the Merger Agreement or

5.24 Legal Duties and Merger Agreement; Acknowledgment. 

(a) Notwithstanding anything to the contrary in this Agreement, nothing in this Agreement shall prevent any person associated with Securityholder who is
a member of the Board of Directors of the Company, in his capacity as such, from (i) participating in or facilitating any action that the Company or its Board of Directors, or members thereof, are permitted to take under the Merger Agreement or
(ii) taking any action that a director of the Company determines in good faith is required to take in satisfaction of his fiduciary duties or in order to comply with applicable Legal Requirements.

Company. Parent and Merger Sub acknowledge and agree that except for representations and warranties expressly set forth in this Agreement, neither the Securityholder nor any representatives of the Securityholder have made any representation or
warranty, express or implied, in connection with this Agreement, the Merger Agreement or Parent’s and the Merger Sub’s investigation of the Company. Parent and the Merger Sub acknowledge and agree that Securityholder shall have no
liability to the Parent or the Merger Sub for any breach of the Merger Agreement. 
 5.25 Convertible Notes; Affiliate Agreements. Securityholder
covenants, acknowledges and agrees, that: 
 (a) At the Effective Time, to the extent the Convertible Notes do not automatically convert in accordance
with the Automatic Conversion provisions described below, Securityholder shall, and shall cause its Affiliates to, sell to the Company, and the Company shall purchase, all of the Convertible Notes owned by Securityholder or any of its Affiliates at
the Effective Time in exchange for a purchase price equal to, for each $1,000 principal amount of Convertible Notes so sold, an amount equal to the Conversion Rate (as defined in the Indenture) on the Conversion Date (as defined in the Indenture)
(and shall be increased pursuant to Section 10.14 of the Indenture in respect of the transactions contemplated by the Merger Agreement as if such Convertible Notes had been converted during the Make-Whole Conversion Period (as defined in the
Indenture) relating to the Merger), multiplied by the price paid per share of Common Stock in the Merger pursuant to the Merger Agreement (i.e., the Merger Consideration), plus all unpaid interest accrued on such Convertible Notes to, but excluding,
such date, which purchase price shall be payable in cash to the Securityholder on the Closing Date (such date of payment, the “Payment Date”). For purposes of the foregoing calculation of the purchase price and for the avoidance of
doubt, the parties agree that the Merger shall constitute a Make-Whole Fundamental Change under the Indenture. Securityholder and the Company agree that, in the event the Payment Date for such repurchase occurs after a record date for payment of
interest with respect to the Convertible Notes so repurchased but on or before the related scheduled interest payment date provided for under the Indenture, the Company shall pay accrued and unpaid interest on the Convertible Notes so repurchased in
accordance with the Indenture (in lieu of paying such accrued interest on the Payment Date). 

  
 12. 

 (b) Securityholder hereby consents to amend the Indenture (including by way of supplemental
indenture), to: 
 (A) provide that: 

(1) if the Merger is consummated with payment to the holders of Common Stock of cash at a price per share of Common Stock (as adjusted for
stock splits, stock dividends or reverse stock splits and combinations) not less than the price per share of Common Stock provided in the Merger Agreement as of August 5, 2021, then, effective at the Effective Time, all outstanding SL
Securities (as defined in the Indenture) shall automatically be converted in accordance with the Indenture, which, for the avoidance of doubt, shall entitle holders of the SL Securities (as defined in the Indenture) to receive as consideration for
such conversion cash in an amount as provided by Section 10.11 of the Indenture giving effect to the Merger at the then applicable Conversion Rate, increased pursuant to Section 10.14 of the Indenture in respect of the Merger (the
“Automatic Conversion”), 
 (2) the consideration for the Automatic Conversion shall be paid to the holders of the SL
Securities on the Closing Date, and 
 (3) SL Securities cannot be exchanged for, and beneficial interests in Global Securities (as defined
in the Indenture) that are SL Securities cannot be exchanged for, Securities that are not SL Securities and that SL Securities need not be held, and beneficial interests in Global Securities (as defined in the Indenture) that are SL Securities need
not be held, by Persons (as defined in the Indenture) who are Purchasers (as defined in the Indenture) or Affiliates (as defined in the Indenture) of Purchasers, and provide that the transfer and exchange provisions and forms contained in the
Indenture shall be modified accordingly, and 
 (4) upon conversion of the Convertible Notes on the Closing Date pursuant to an Automatic
Conversion, the Company will pay to each converting holder of Convertible Notes accrued but unpaid interest on such Convertible Notes to, but excluding, the Closing Date, and that, in connection with such conversion, the last sentence of
Section 10.02(d) of the Indenture will not apply, and 
 (B) add at the end of Section 4.07 of the Indenture the following words,
“Notwithstanding anything to the contrary in this Section 4.07, this Section 4.07 shall not apply from and after the Closing (as defined in the Agreement and Plan of Merger, dated as of August 5, 2021, among Sunshine Software
Holdings, Inc. (“Parent”), Sunshine Software Merger Sub, Inc. (“Merger Sub”) and the Company (as it may be amended from time to time, the “Merger Agreement”)) and shall not restrict any further incurrence of
Indebtedness from time to time in such amounts as determined by the Company, provided that (x) such Closing occurs prior to the date that is five (5) business days following February 5, 2022, and (y) on the date of such Closing,
some or all of the proceeds of any borrowing by the Company on the date of Closing (as defined in the Merger Agreement) and other available funds are deposited with the Paying Agent (as defined in the Merger Agreement) for payment of the Merger
Consideration (as defined in the Merger Agreement) at a price per share of Common Stock (as adjusted for stock splits, stock dividends, reverse stock splits and combinations) converted into the right to receive the Merger Consideration that is not
less than the price per share of Common Stock provided in the Merger Agreement as of August 5, 2021, to repay outstanding Indebtedness of the Company and its Subsidiaries to the extent required by the Merger Agreement, and to pay in full on the
date of Closing the consideration due upon conversion or repurchase of the SL Securities in connection with the Merger (as defined in the Merger Agreement) (which consideration due shall be (I) in the case of a conversion, the amount described
in Section 5.25(b)(A)(1) and (A)(4) of each of the Support Agreements, dated as of August 5, 2021 among Sunshine Software Holdings, Inc. Sunshine Software Merger Sub, Inc., the Company and, respectively, SLA CM Chicago Holdings, L.P. and
SLA Chicago Co-Invest II, L.P. (the “Support Agreements”) and (II) in the case of a repurchase, the amount described in Section 5.25(a) of the Support Agreements (subject, as to timing, to
the last sentence of such 5.25(a), as applicable)), and to pay expenses related to the transactions contemplated by the Merger Agreement to the extent required by the Merger Agreement.” 

  
 13. 

 Securityholder acknowledges that this Section 5.25(b) is intended to be (i) a
consent contemplated by Article 9 of the Indenture to each of the foregoing amendments described in clauses (A) and (B) above (each an “Indenture Amendment” and collectively, the “Indenture
Amendments”) upon which the Company and the Trustee (as defined in the Indenture) can conclusively rely in connection with effecting the Indenture Amendments and that the Company intends to (unless Parent otherwise requests in writing)
effect both Indenture Amendments (the Indenture Amendments so effected, the “applicable Indenture Amendments”) and (ii) irrevocable as long as this Agreement is in effect. Securityholder agrees to use reasonable best
efforts to take all actions reasonably necessary on its part to cause the applicable Indenture Amendments to be effective in a manner reasonably requested by Parent or the Company as promptly as practicable after the public announcement of the
Merger Agreement and in any event no later than 25 business days after the date hereof, and to take all action required on its part, in the case of the distribution of a consent solicitation, to cause the submission of consents in accordance with
the applicable procedures of the Depository (as defined in the Indenture) promptly after the distribution thereof through the facilities of the Depository). Securityholder and the Company agree that Section 4.14 of the Investment Agreement
shall be of no further effect from and after the date of this Agreement. 
 (c) Securityholder hereby agrees to take any and all actions to cause all
of the Affiliate Agreements to be terminated (without payment or other consideration or concession by Parent, the Company or any of their Subsidiaries except as otherwise provided herein or therein), effective as of and contingent upon the Closing
and payment of the consideration payable in respect of the Automatic Conversion, such that such agreements shall be of no further force or effect immediately thereafter, except for (i) any rights, obligations or other provisions that survive
termination of such agreements by their terms, (ii) unpaid expense reimbursement or other fees or compensation owed to Securityholder or its affiliates or representatives, including any director designee, (iii) any indemnification
provisions inuring to the benefit of Securityholder, its affiliates or representatives, including any director designee, in connection with Securityholder’s investment in the Company and (iv) to the extent that a party thereunder may seek
recourse for any breach thereof. 
 (d) If the Closing occurs, this Section 5.25 shall survive any Expiration Date to the extent
necessary for performance of this Section 5.25 to be completed. 
 5.26. Registration Waiver. After the execution of this
Agreement and until termination of this Agreement in accordance with its terms, Securityholder, on behalf of itself and its affiliates, waives any requirement of the Company to register the Convertible Notes for resale and any event of default in
relation thereto. 
 5.27 Construction. 
 (a) For
purposes of this Agreement, whenever the context requires: the singular number shall include the plural, and vice versa; the masculine gender shall include the feminine and neuter genders; the feminine gender shall include the masculine and neuter
genders; and the neuter gender shall include masculine and feminine genders. 
 (b) The parties have participated jointly in negotiating and drafting
this Agreement. In the event that an ambiguity or a question of intent or interpretation arises, this Agreement shall be construed as if drafted jointly by the parties, and no presumption or burden of proof shall arise favoring or disfavoring any
party by virtue of the authorship of any provision of this Agreement. 

  
 14. 

 (c) As used in this Agreement, the words “include” and “including,” and
variations thereof, shall not be deemed to be terms of limitation, but rather shall be deemed to be followed by the words “without limitation.” 

(d) Except as otherwise indicated, all references in this Agreement to “Sections” and “Exhibits” are intended to refer to Sections
of this Agreement and Exhibits to this Agreement, and the words “herein,” “hereof” and “hereunder,” and words of similar import, shall be construed to refer to this Agreement in its entirety and not to any particular
provision of this Agreement. The word “or” when used in this Agreement is not exclusive. The word “extent” in the phrase “to the extent” shall mean the degree to which a subject or other thing extends, and such phrase
shall not mean simply “if”. 
 5.28 Termination. This Agreement shall terminate automatically upon the first to occur of (a) the
termination of the Merger Agreement in accordance with its terms, (b) the later of (i) the Effective Time and (ii) the performance by all parties of all obligations hereunder, (c) the date that is five (5) business days
following February 5, 2022 and (d) the date of any Adverse Amendment. An “Adverse Amendment” means an amendment or modification to the Merger Agreement or a document ancillary thereto, or a waiver of a provision therein,
in a manner that (i) decreases the amount or changes the kind of consideration to be paid to the Company’s stockholders in connection with the Merger, or (ii) increases the obligations or liabilities of Securityholder under this
Agreement.
