issued after date of this Certificate of Designations by the Company the terms of which do not expressly provide that such shares of capital stock rank on a parity with or senior to the Series E Preferred Stock as to dividend rights and rights on

 7 








 (b) Liquidation Preference. In the event of any liquidation, dissolution or winding
up of the affairs of the Company, whether voluntary or involuntary, Holders shall be entitled to receive for each share of Series E Preferred Stock, out of the assets of the Company or proceeds thereof (whether capital or surplus) available for
distribution to stockholders of the Company, subject to the rights of any creditors of the Company, before any distribution of such assets or proceeds is made to or set aside for the holders of Common Stock or any other Junior Securities, an amount
equal to the greater of (i) the sum of (A) $100.00 per share of the Series E Preferred Stock (as adjusted for any split, subdivision, combination or consolidation, recapitalization or similar event with respect to the Series E Preferred
Stock) and (B) the amount of any declared, but unpaid, Distributions to the date of payment and (ii) the amount such Holder would have received if such share of Series EPreferred Stock had been fully converted into shares of Common Stock
in accordance with this Certificate of Designations immediately prior to such liquidation, dissolution or winding up (such greater amount of the foregoing clauses (i) and (ii), the “Liquidation Preference”). 

(c) Partial Payment. If, in any distribution described in Section 4 and this Section 5, the assets of the Company or
proceeds thereof are not sufficient to pay in full the amounts payable with respect to all outstanding shares of Series E Preferred Stock and the corresponding amounts payable with respect to any other stock of the Company ranking equally with
Series E Preferred Stock as to such distribution, Holders and the holders of such other stock shall share ratably in any such distribution in proportion to the full respective distributions to which they are entitled. 

(d) Change in Control; Deemed Liquidations. Not less than twenty calendar days prior to the date that a contemplated Change of
Control is expected to be consummated, the Company shall notify each Holder of the anticipated consummation date of such Change of Control by written notice via facsimile or email and overnight courier. Upon the election of a Holder (an
“Electing Holder”) in writing given to the Company not later than five Business Days prior to the anticipated consummation date in the foregoing notice, the consummation by the Company of a Change of Control will constitute a
liquidation, dissolution or winding up of the Company (a “Deemed Liquidation”) solely with respect to any or all of the Series C Preferred Stock held by such Holders and, upon such election, shall have the right to receive a
distribution in accordance with this Section 5 (a “Deemed Liquidation Payment”). The Company shall make payment of the Deemed Liquidation Payment to any Electing Holder concurrently with the consummation of such Change of
Control and in the event that the Company does not pay the Deemed Liquidation Payment on such date, an Electing Holder shall have the right to void its election. If the Company fails to pay the Deemed Liquidation Payment in full when due in
accordance with this Section 5(d), the Company will pay interest thereon at a rate equal to the lesser of 25% per annum and the maximum rate permitted by applicable law, accruing daily from such date until the Deemed Liquidation Payment,
plus all such interest thereon, is paid in full. Nothing herein shall limit a Holder's right to pursue any other remedies available to it hereunder, at law or in equity including, without limitation, a decree of specific performance and/or
injunctive relief with respect to the Company's failure to comply with its obligations under this Section 5(d).

(a) Series C Preferred Stock. Each share of Series E Preferred Stock shall be convertible at any time into one share of Series C
Preferred Stock in the manner set forth in Section 6(c); provided no such conversion may result in a Holder, together with all BHC Affiliates of the Holder, owning or controlling in the aggregate more than a 4.99% Voting Ownership
Interest, excluding for the purpose of this calculation any reduction in ownership resulting from transfers by such Holder and its BHC Affiliates of Voting Securities of the Company.

the closing of a transfer to a transferee of such Series E Preferred Stock pursuant to a Permitted Transfer (an “Eligible Transferee”) and (ii) at the sole discretion of the Eligible Transferee into a number of shares of Common
Stock equal to the then applicable Conversion Rate in the manner set forth in Section 6(c) upon written notice from the Eligible Transferee. The number of shares of Common Stock into which a share of Series C Preferred Stock shall be
convertible shall be determined by dividing (i) $100.00 (as adjusted for any split, subdivision, combination or consolidation, recapitalization or similar event with respect to the Series E Preferred Stock) by (ii) the then Conversion
Price (subject to the conversion procedures set forth below in Section 6(c)).

shares of Series E Preferred Stock in shares of Series C Preferred Stock pursuant to Section 6(a), in each case at any time in whole or from time to time in part, as and when provided in Section 6 upon written notice delivered to the

outstanding shares of Series E Preferred Stock (“Certificate(s)” and together with the Conversion Notice, the “Conversion Documents”). The conversion date for such conversion shall be the date on which the Company

the shares of Common Stock or Series C Preferred Stock, as applicable, issuable upon such conversion shall be treated for all purposes as the record holder of such shares of Common Stock or Series C Preferred Stock on the Conversion Date.

 (ii) Upon receipt by the Company of the Conversion Documents, the Company shall, as soon as practicable, but in any event
within one Trading Day thereafter, send, via facsimile or email, a confirmation of receipt and copies of such Conversion Documents to such Eligible Transferee or Holder and to the transfer agent, which confirmation shall constitute an instruction to
the transfer agent to process such Conversion Notice in accordance with the 

  
 9 








 
terms herein and as soon as practicable following the Conversion Date (and in any event within three Trading Days thereafter (the “Share Delivery Date”) and (A) provided the

Automated Securities Transfer Program or if such Eligible Transferee or Holder elected (in the Conversion Notice) to not have the shares of Common Stock or shares of Series C Preferred Stock credited to such Eligible Transferee’s or
Holder’s balance account with DTC, issue and deliver, to the address as specified in the Conversion Notice, one or more certificates representing shares of Common Stock to which such Eligible Transferee or Holder shall be entitled. In the event
less than all of the shares of Series E Preferred Stock represented by a Certificate are being converted into Common Stock or Series C Preferred Stock by an Eligible Transferee or a Holder, as applicable, a new Certificate, of like tenor, at the
Company’s sole cost and expense, shall be issued and delivered promptly (and in no event later than the Share Delivery Date) to such Eligible Transferee or Holder representing the number of such shares of Series E Preferred Stock that are not
being converted. 
 (iii) From and after the Conversion Date, the shares of Series E Preferred Stock to be converted on such
Conversion Date will no longer be deemed to be outstanding and all rights of the Eligible Transferee or Holder, as applicable, as Holder (except the right to receive the Common Stock or Series C Preferred Stock upon conversion) shall cease and
terminate with respect to such shares; provided that a Holder shall be entitled to receive any Distributions that were declared prior to, but remain unpaid as of, the Conversion Date; provided further that in the event that a share of
Series E Preferred Stock is not converted due to a default by the Company or because the Company is otherwise unable to issue the requisite shares of Common Stock or Series C Preferred Stock, such share of Series E Preferred Stock will remain

 (iv) The Company acknowledges that a breach by it
of its obligations under this Section 6(c) will cause irreparable harm to an Eligible Transferee and/or a Holder, as applicable. Accordingly, the Company acknowledges that the remedy at law for a breach of its obligations under this
Section 6(c) will be inadequate and agrees, in the event of a breach or threatened breach by the Company of the provisions of this Section 6(c), that an Eligible Transferee or a Holder shall be entitled, in addition to all other available
remedies, to an order and/or injunction restraining any breach and requiring immediate issuance, without the necessity of showing economic loss and without any bond or other security being required. 

(d) No Impairment. The Company will not, by amendment of its Certificate of Incorporation or through any reorganization, transfer
of assets, consolidation, merger, dissolution, issue or sale of securities or any other voluntary action, avoid or seek to avoid the observance or performance of any of the terms to be observed or performed hereunder by the Company, but will at all
times in good faith assist in the carrying out of all the provisions of Section 7 and this Section 6 and in the taking of all such actions as may be necessary or appropriate in order to protect the conversion rights of any Eligible
Transferee and/or any Holder, as applicable, against impairment.

reserve and keep available out of its authorized but unissued (i) Common Stock and (ii) Series C Preferred Stock, in each case solely for the purpose of effecting the conversion of the Series E Preferred Stock such number of shares of
Common Stock and Series C Preferred Stock as will from time to time be sufficient to effect the conversion of all outstanding Series E Preferred Stock (the “Required Reserve Amount”). If at any time while any shares of Series E
Preferred Stock remain outstanding the Company does not have a sufficient number of authorized and unreserved shares of Common Stock and/or Series C Preferred Stock, as applicable, to satisfy its obligation to reserve for issuance upon conversion of
the Series E Preferred Stock at least a number of shares of Common Stock and/or Series C Preferred Stock, as applicable, equal to the Required Reserve Amount (an “Authorized Share Failure”), then the Company shall immediately take
all action necessary to increase the Company’s authorized shares of Common Stock and/or Series C Preferred Stock, as applicable, to an amount sufficient to allow the Company to reserve the Required Reserve Amount for the shares of Series E
Preferred Stock then outstanding. Without limiting the generality of the foregoing sentence, as soon as practicable after the date of the occurrence of an Authorized Share Failure, but in no event later than 60 days after the occurrence of such
Authorized Share Failure, the Company shall file a proxy statement for a special meeting of its stockholders for the approval of an increase in the number of authorized shares of Common Stock and/or Series C Preferred Stock, as applicable. In

to unanimously recommend to the stockholders that they approve such proposal.

Delivery Date, the Company shall fail to issue and deliver to an Eligible Transferee or a Holder, as applicable, (i) the number of shares of Common Stock or Series C Preferred Stock, as applicable, to which such Eligible Transferee or Holder is
entitled hereunder upon such Eligible Transferee’s or Holder’s conversion of the Series E Preferred Stock or (ii) a new certificate representing the number of shares of Series E Preferred Stock that are not being converted, in
addition to all other available remedies to which such Eligible Transferee or Holder may pursue hereunder and under the Transaction Documents, the Company shall pay additional damages to such Eligible Transferee or Holder on each Business Day after
the Share Delivery Date that such conversion is not timely effected in an amount equal to 0.5% of the product of (A) the number of shares of Common Stock (in the case of a conversion into Common Stock) or the number of Common Stock issuable
upon conversion of the shares of Series C Preferred Stock (in the case of a conversion into Series C Preferred Stock), as applicable, not issued to such Eligible Transferee or Holder by the Share Delivery Date and to which such Eligible Transferee
or Holder is entitled (or in the case of failure to deliver a new certificate representing shares of Series E Preferred Stock not being converted, the number of shares of Common Stock issuable upon conversion of such shares of Series E Preferred
Stock (assuming that a Permitted Transfer was made to an Eligible Transferee) that would be represented by such certificate as of the Share Delivery Date), multiplied by (B) the Closing Price of the Common Stock on the Share Delivery Date. If
the 

  
 11 









 Company fails to pay the damages set forth in this Section 6(f) within five Business Days of the date
incurred, then such payments shall bear interest at the rate of 1.5% per month (pro rated for partial months) until such payments are made. Nothing herein shall limit an Eligible Transferee’s or a Holder’s right to pursue any other
remedies available to it hereunder, at law or in equity including, without limitation, a decree of specific performance and/or injunctive relief with respect to the Company’s failure to timely deliver shares of Common Stock, Series C Preferred

Stock. In the event that the Company at any time or from time to time shall effect a division of the Series C Preferred Stock into a greater number of shares (by stock split, reclassification or otherwise than by payment of distributions in
Series C Preferred Stock or in any right to acquire the Series C Preferred Stock) and a corresponding division is not made with respect to the Series E Preferred Stock, the number of shares of Series C Preferred Stock issuable on conversion of each
share of Series E Preferred Stock shall be increased in proportion to such increase in the aggregate number of shares of Series C Preferred Stock outstanding. In the event the outstanding Series C Preferred Stock shall be combined or consolidated,
by reclassification, reverse stock split or otherwise, into a lesser number of shares of the Series C Preferred Stock and a corresponding combination or consolidation is not made with respect to the Series E Preferred Stock, the number of shares of
Series C Preferred Stock issuable on conversion of each share of Series E Preferred Stock shall be decreased in proportion to such decrease in the aggregate number of shares of Series C Preferred Stock outstanding. Any adjustment under this Section
shall become effective at the close of business on the date the subdivision or combination becomes effective. 
 (ii) Common
Stock. In the event that the Company at any time or from time to time shall effect a division of the Common Stock into a greater number of shares (by stock split, reclassification or otherwise than by payment of distributions in Common Stock or
in any right to acquire the Common Stock), the Conversion Price in effect immediately before that subdivision shall be proportionately decreased so that the number of shares of Common Stock issuable on conversion of each share of Series E Preferred
Stock shall be increased in proportion to such increase in the aggregate number of shares of Common Stock outstanding. In the event the outstanding Common Stock shall be combined or consolidated, by reclassification, reverse stock split or
otherwise, into a lesser number of shares of the Common Stock, the Conversion Price in effect immediately before such combination shall be proportionately increased so that the number of shares of Common Stock issuable on conversion of each share of
Series E Preferred Stock shall be decreased in proportion to such decrease in the aggregate number of shares of Common Stock outstanding. Any adjustment under this Section shall become effective at the close of business on the date the subdivision
or combination becomes effective.

 (b) Adjustments for Reclassification and Reorganization. If the Common Stock or
Series C Preferred Stock, as applicable, issuable upon conversion of the Series E Preferred Stock shall be changed into the same or a different number of shares of any other class or classes of stock, whether by capital reorganization,
consolidation, reclassification or otherwise (other than a division or combination of shares provided for in Section 7(a)), an Eligible Transferee’s or a Holder’s, as applicable, right to convert the Series E Preferred Stock then in
effect shall, concurrently with the effectiveness of such transaction, be proportionately adjusted so that the Series E Preferred Stock shall be convertible into, in lieu of the number of shares of Common Stock or Series C Preferred Stock, as
applicable, which such Eligible Transferee or Holder would otherwise have been entitled to receive, a number of shares of such other class or classes of stock equivalent to the number of such shares that would have been subject to receipt by such
Eligible Transferee or Holder upon conversion of the Series E Preferred Stock into Common Stock or Series C Preferred Stock, as applicable, immediately before that change. 
 (c) Adjustment for Dividends and Distributions. 
 (i) Common Stock.
In the event the Company at any time or from time to time shall make or issue, or fix a record date for the determination of holders of Common Stock entitled to receive, a Distribution payable on the Common Stock in additional shares of Common
Stock, then and in each such event the Conversion Price in effect immediately before such event shall be decreased as of the time of such issuance or, in the event such a record date shall have been fixed, as of the close of business on such record
date, by multiplying the Conversion Price then in effect by a fraction: 
 (A) the numerator of which shall be the total number
of shares of Common Stock issued and outstanding immediately prior to the time of such issuance on the close of business on such record date, and 
 (B) the denominator of which shall be (A) the total number of shares of Common Stock issued and outstanding immediately after prior to the time of such issuance on the close of business on such
record date plus (B) the number of shares of Common Stock issuable in payment of such dividend or distribution. 
 Notwithstanding
the foregoing, however, if such record date shall have been fixed and such Distribution is not fully paid on the date fixed therefor, the Conversion Price shall be recomputed accordingly as of the close of business on such record date and thereafter
the Conversion Price shall be adjusted pursuant to this Section 7(c) as of the time of actual payment of such Distribution. 
 (ii) Series C Preferred Stock. In the event the Company at any time or from time to time shall make or issue, or fix a record date for the determination of holders of Series C Preferred Stock
entitled to receive, a Distribution payable on the Series C Preferred Stock in additional shares of Series C Preferred Stock and a corresponding Distribution in shares of Series E Preferred Stock is not made with respect to the Series E Preferred
Stock, then and in each such event the number of shares of Series C Preferred Stock issuable on conversion of each share of Series E Preferred Stock shall be increased in proportion to the increase in the aggregate number of shares of Series C
Preferred Stock outstanding.

 (d) Certificates as to Adjustments. Upon the occurrence of each adjustment or
readjustment pursuant to this Section 7, the Company at its expense shall, as promptly as reasonably practicable but in any event not later than five Business Days thereafter, compute such adjustment or readjustment in accordance with the terms
hereof and prepare and furnish to each Holder and Eligible Transferee a certificate executed by the Company’s President and Chief Executive Officer (or other appropriate officer) setting forth such adjustment or readjustment and showing in
detail the facts upon which such adjustment or readjustment is based. The Company shall, as promptly as reasonably practicable after the written request at any time of any Holder or Eligible Transferee (but in any event not later than five Business
Days following such request), furnish or cause to be furnished to such Holder or Eligible Transferee a like certificate setting forth (i) such adjustments and readjustments, and (ii) the number of shares of Common Stock, the number of
shares of Series C Preferred Stock and the amount, if any, of other property which at the time would be received upon the conversion of the Series E Preferred Stock. 
 8. Redemption. Except as set forth in Section 5(d), the Series E Preferred Stock shall not be redeemable either at the Company’s option or at the option of the Holders at any time.
Notwithstanding the foregoing, the Company shall not be prohibited from repurchasing or otherwise acquiring shares of Series E Preferred Stock in voluntary transactions; provided that Company must offer to repurchase shares of Series C Preferred
Stock, Series D Preferred Stock and Series E Preferred Stock on a pro rata basis among the Holders, the holders of Series C Preferred Stock and the holders of Series D Preferred Stock. Subject to Section 10, any shares of Series E Preferred
Stock repurchased or otherwise acquired may be cancelled by the Company and thereafter be reissued as shares of any series of preferred stock of the Company. The Company may not purchase, repurchase or redeem any Junior Securities (other than
pursuant to equity incentive agreements with employees giving the Company the right to repurchase Junior Securities upon the termination of services at cost). 
 9. Voting Rights. Holders of the Series E Preferred Stock shall not have any voting rights except as otherwise required by Section 10 or from time to time under applicable law. 

10. Protective Provisions. So long as any shares of Series E Preferred Stock are issued and outstanding, the Company will not
(including by means of merger, consolidation or otherwise), without obtaining the approval (by vote or written consent) of the Holders of a majority of the issued and outstanding shares of Series E Preferred Stock, (a) issue additional amounts
or classes of Senior Securities, (b) modify the terms of the Series E Preferred Stock so as to significantly and adversely affect its rights or preference, as reasonably determined by the Holders, (c) liquidate, dissolve or wind-up the
business and affairs of the Company in any form of transaction, or consent to any of the foregoing, (d) pay dividends when preferred dividends on the Series E Preferred Stock are in arrears or (e) take any other action which, under the
laws of Delaware or any other applicable law, requires the prior approval (by vote or written consent) of the Series E Preferred Stock voting as a separate class.

 11. Assumption. Upon the occurrence of any Reorganization, the Company shall cause
the Surviving Party to, and the Surviving Party shall, be substituted for the Company (so that from and after the date of such Reorganization, the provisions of this Certificate of Designations referring to the “Company” shall refer
instead to such Surviving Party) and succeed to and assume all of the obligations, rights and powers of the Company under this Certificate of Designations with the same effect as if such Surviving Party had been named as the Company herein with
respect to the shares of Series E Preferred Stock of any Holder who elects such assumption. Upon consummation of such Reorganization, the Surviving Party shall deliver to each Holder that (a) did not elect to treat such Reorganization (if such
Reorganization constitutes a Change in Control) as a Deemed Liquidation with respect to all such Holder’s shares of Series E Preferred Stock and (b) elected to have such Surviving Party succeed to the Company’s obligations hereunder,
confirmation that there shall be issued upon conversion of the shares of Series E Preferred Stock at any time after the consummation of such Reorganization, in lieu of the shares of Common Stock and/or Series C Preferred Stock issuable upon the
conversion of the shares of Series E Preferred Stock prior to such Reorganization, such shares of common stock or preferred stock (or their equivalent) of the Surviving Party, as adjusted to reflect the value of such Reorganization, in accordance
with the provisions of this Certificate of Designations. The provisions of this Section 11 shall apply similarly and equally to successive Reorganizations and shall be applied without regard to any limitations on the conversion of the shares of
Series E Preferred Stock. 
 12. Taxes. 
 (a) If the Company believes that it is required to make a deduction or withholding for or on account of tax from a payment due to a Holder under this Certificate of Designations (or that there is a change
in the rate or the basis of such deduction or withholding), the Company shall notify the affected Holders promptly and provide such Holders with a reasonable opportunity to provide any necessary information that may enable the Holders to avoid such
deduction or withholding. 
 (b) The Company shall pay any documentary, stamp or similar issue or transfer tax due on the issue
of Common Stock or Series C Preferred Stock upon conversion or due upon the issuance of a new Certificate for any shares of Series E Preferred Stock not converted, except for any documentary, stamp or similar issue or transfer tax due because any
shares of Common Stock, Series C Preferred Stock or Series E Preferred Stock are issued in a name other than the name of the converting Holder. 
 13. Notices. Any notice required by the provisions hereof to be given must be made in writing and will be deemed delivered: (i) upon receipt, when delivered personally; (ii) upon receipt,
when sent by facsimile (provided confirmation of transmission is mechanically or electronically generated and kept on file by the sending party); (iii) one Business Day after deposit with an overnight courier service or (iv) five days
after being sent by certified or registered mail, in each case properly addressed to the party to receive such notice. Unless the Company otherwise provides the Holders notice thereof in accordance with this Section 13, the Company’s
address for notices hereunder shall be 357 Roosevelt Road, Glen Ellyn, Illinois 60137. 

  
 15 









 14. Record Holders. To the fullest extent permitted by law, the Company will be
entitled to recognize the Holder of record as the true and lawful owner thereof for all purposes and will not be bound to recognize any equitable or other claim to or interest in such share or shares on the part of any other person, whether or not
it will have express or other notice thereof. 
 15. No Preemptive Rights. Except as otherwise set forth in any agreement
with the Company, no share of Series E Preferred Stock has any rights of preemption whatsoever as to any securities of the Company, or any warrants, rights or options issued or granted with respect thereto, regardless of how such securities, or such
warrants, rights or options, may be designated, issued or granted. 
 16. Other Rights. The shares of Series E Preferred
Stock have no rights, preferences, privileges or voting powers or relative, participating, optional or other special rights, or qualifications, limitations or restrictions thereof, other than as set forth herein or as provided by applicable law.
