Investments, acquisitions, dispositions, mergers, amalgamations, consolidations, discontinued operations and other operational changes (and the change in any associated fixed charge obligations
and the change in EBITDA resulting therefrom) had occurred on the first day of the four-quarter reference period. If since the beginning of such period any Person that subsequently became a Restricted Subsidiary or was merged with or into Milacron
or any of the Restricted Subsidiaries since the beginning of such period shall have made any Investment, acquisition, disposition, merger, amalgamation, consolidation, discontinued operation or operational change, in each case with respect to an
operating unit of a business, that would have required adjustment pursuant to this definition, then the Fixed Charge Coverage Ratio shall be calculated giving pro forma effect thereto for such period as if such Investment, acquisition, disposition,
merger, consolidation, discontinued operation or operational change had occurred at the beginning of the applicable four-quarter period. 

For purposes of this definition, whenever pro forma effect is to be given to any Investment, acquisition, disposition, merger, amalgamation,
consolidation, discontinued operation or operational change, the pro forma calculations shall be made in good faith by a responsible financial or accounting officer of Milacron. Any such pro forma calculation may include (1) adjustments of the
nature used in connection with the calculation of “Adjusted EBITDA” as set forth in note 1 to “Summary—Summary Historical and Unaudited Pro Forma Condensed Consolidated Financial and Other Data” in the Offering Memorandum,
(2) adjustments calculated in accordance with Regulation S-X under the Securities Act and (3) adjustments to give effect to any Pro Forma Cost Savings in an amount pursuant to this clause (3) not to exceed 30% of EBITDA for the
applicable four-quarter reference period before giving effect to such Pro Forma Cost Savings. 
 If any Indebtedness bears a floating rate
of interest and is being given pro forma effect, the interest on such Indebtedness shall be calculated as if the rate in effect on the Fixed Charge Coverage Ratio Calculation Date had been the applicable rate for the entire period (taking into
account any Hedging Obligations applicable to such Indebtedness). Interest on a Capitalized Lease Obligation shall be deemed to accrue at an interest rate reasonably determined by a responsible financial or accounting officer of Milacron to be the
rate of interest implicit in the Capitalized Lease Obligation in accordance with GAAP. For purposes of making the computation referred to above, interest on any Indebtedness under a revolving credit facility computed on a pro forma basis shall be
computed based upon the average daily balance of such Indebtedness during the applicable period. Interest on Indebtedness that may optionally be determined at an interest rate based upon a factor of a prime or similar rate, a Eurocurrency interbank
offered rate, or other rate, shall be deemed to have been based upon the rate actually chosen, or, if none, then based upon such optional rate chosen as Milacron may designate.

with Section 2.06 hereof. The Issuers may appoint one or more co-registrars and one or more additional paying agents. The term “Registrar” includes any co-registrar, and the term “Paying Agent” includes any additional paying
agents. The Issuers initially appoint the Trustee as Paying Agent. The Issuers may change any Paying Agent or Registrar without prior notice to any Holder. The Issuers shall notify the Trustee in writing of the name and address of any Agent not a
party to this Indenture. If the Issuers fail to appoint or maintain another entity as Registrar or Paying Agent, the Trustee shall, to the extent that it is capable, act as such. Milacron or any Restricted Subsidiary may act as Paying Agent or
Registrar. 
 (b) The Issuers initially appoint The Depository Trust Company (“DTC”) to act as Depositary with respect to
the Global Notes representing the Notes. 
 (c) The Issuers initially appoint the Trustee to act as the Registrar for the Notes and to act as

 Section 2.04.
PAYING AGENT TO HOLD MONEY IN TRUST 

The Issuers shall require each Paying Agent other than the Trustee to agree in writing that the Paying Agent shall hold in trust for the
benefit of Holders or the Trustee all money held by the Paying Agent for the payment of principal, premium, if any, or interest on the Notes, and will notify the Trustee in writing of any default by the Issuers in making any such payment. While any
such default continues, the Trustee may require a Paying Agent to pay all money held by it to the Trustee. The Issuers at any time may require a Paying Agent to pay all money held by it to the Trustee. Upon payment over to the Trustee, the Paying
Agent (if other than an Issuer or a Subsidiary) shall have no further liability for such funds. If Milacron or a Restricted Subsidiary acts as Paying Agent, it shall segregate and hold in a separate trust fund for the benefit of the Holders all
funds held by it as Paying Agent. Upon any Event of Default pursuant to Section 6.01(f) or (g), the Trustee shall serve as Paying Agent for the Notes. 

Section 2.05. HOLDER LISTS

 The Trustee shall preserve in as current a form as is reasonably practicable the most recent list available to it of the names and
addresses of all Holders and shall otherwise comply with Trust Indenture Act Section 312(a). If the Trustee is not the Registrar, the Issuers shall furnish to the Trustee at least five Business Days before each Interest Payment Date and at such
other times as the Trustee may request in writing, a list in such form and as of such date as the Trustee may reasonably require of the names and addresses of the Holders and the Issuers shall otherwise comply with Trust Indenture Act

Cancellation and/or Adjustment of Global Notes. At such time as all beneficial interests in a particular Global Note have been exchanged for Definitive Notes or a particular Global Note has been redeemed,
repurchased or canceled in whole and not in part, each such Global Note shall be returned to or retained and canceled by the Trustee in accordance with Section 2.11 hereof. At any time prior to such cancellation, if any beneficial interest in a
Global Note is exchanged for or transferred to a Person who will take delivery thereof in the form of a beneficial interest in another Global Note or for Definitive Notes, the aggregate principal amount of Notes represented by such Global Note shall
be reduced accordingly and an endorsement shall be made on such Global Note by the Trustee or by the Depositary at the direction of the Trustee to reflect such reduction; and if the beneficial interest is being exchanged for or transferred to a
Person who will take delivery thereof in the form of a beneficial interest in another Global Note, such other Global Note shall be increased accordingly and an endorsement shall be made on such Global Note by the Trustee or by the Depositary at the

Definitive Notes upon receipt of an Authentication Order in accordance with Section 2.02 hereof or at the Registrar’s request. 

(ii) No service charge shall be made to a holder of a beneficial interest in a Global Note or to a Holder of a Definitive Note for any
registration of transfer or exchange, but the Issuers may require payment of a sum sufficient to cover any transfer tax or similar governmental charge payable in connection therewith (other than any such transfer taxes or similar governmental charge
payable upon exchange or transfer pursuant to Sections 2.07, 2.10, 3.06, 3.09, 4.10, 4.14 and 9.05 hereof). 
 (iii) All Global Notes and
Definitive Notes issued upon any registration of transfer or exchange of Global Notes or Definitive Notes shall be the valid obligations of the Issuers, evidencing the same debt, and entitled to the same benefits under this Indenture, as the Global
Notes or Definitive Notes surrendered upon such registration of transfer or exchange. 
 (iv) Neither the Registrar nor the Issuers shall
not be required (A) to issue, to register the transfer of or to exchange any Notes during a period beginning at the opening of business 15 days before the day of any selection of Notes for redemption under Section 3.02 hereof and ending at
the close of business on the day of selection, (B) to register the transfer of or to exchange any Note so selected for redemption in whole or in part, except the unredeemed portion of any Note being redeemed in part or (C) to register the
transfer of or to exchange a Note between a Record Date with respect to such Note and the next succeeding Interest Payment Date with respect to such Note. 

(v) Prior to due presentment for the registration of a transfer of any Note, the Trustee, any Agent and the Issuers may deem and treat the
Person in whose name any Note is registered as the absolute owner of such Note for the purpose of receiving payment of principal of (and premium, if any) and interest on such Notes and for all other purposes, and none of the Trustee, any Agent or
the Issuers shall be affected by notice to the contrary. 

  
 -44- 








 (vi) Upon surrender for registration of transfer of any Note at the office or agency of the
Issuers designated pursuant to Section 4.02 hereof, the Issuers shall execute, and the Trustee shall authenticate and deliver, in the name of the designated transferee or transferees, one or more replacement Notes of any authorized denomination
or denominations of a like aggregate principal amount. 
 (vii) At the option of the Holder, Notes may be exchanged for other Notes of any
authorized denomination or denominations of a like aggregate principal amount upon surrender of the Notes to be exchanged at such office or agency. Whenever any Global Notes or Definitive Notes are so surrendered for exchange, the Issuers shall
execute, and the Trustee shall authenticate and deliver, the replacement Global Notes and Definitive Notes which the Holder making the exchange is entitled to in accordance with the provisions of Section 2.02 hereof. 

(viii) All certifications, certificates and Opinions of Counsel required to be submitted pursuant to this Section 2.06 to effect a
registration of transfer or exchange may be submitted by facsimile. 
 (ix) The Trustee shall have no obligation or duty to monitor,
determine or inquire as to compliance with any restrictions on transfer imposed under this Indenture or under applicable law with respect to any transfer of any interest in any Note (including any transfers between or among Depositary Participants
or beneficial owners of interest in any Global Note) other than to require delivery of such certificates and other documentation or evidence as are expressly required by, and to do so if and when expressly required by the terms of, this Indenture,
and to examine the same to determine substantial compliance as to form with the express requirements hereof. 
 Section 2.07.
REPLACEMENT NOTES 
 If any
mutilated Note is surrendered to the Trustee, the Registrar or either Issuer and the Trustee receives evidence to its satisfaction of the ownership and destruction, loss or theft of any Note, the Issuers shall issue and the Trustee, upon receipt of
an Authentication Order, shall authenticate a replacement Note if the Trustee’s requirements are met. If required by the Trustee or the Issuers, an indemnity bond must be supplied by the Holder that is sufficient in the judgment of (i) the
Trustee to protect the Trustee and (ii) the Issuers to protect the Issuers, the Trustee, any Agent and any authenticating agent from any loss that any of them may suffer if a Note is replaced. The Issuers and the Trustee may charge the Holder
for their expenses in replacing a Note. 
 Every replacement Note issued in accordance with the Section 2.07 is a contractual
obligation of the Issuers and shall be entitled to all of the benefits of this Indenture equally and proportionately with all other Notes duly issued hereunder. 

Section 2.08. OUTSTANDING NOTES

 The Notes outstanding at any time are all the Notes authenticated by the Trustee except for those canceled by it, those delivered to
it for cancellation, those reductions in the interest in a Global Note effected by the Trustee in accordance with the provisions hereof and those described in this Section 2.08 as not outstanding. Except as set forth in Section 2.09
hereof, a Note does not cease to be outstanding because an Issuer, a Guarantor or an Affiliate of an Issuer or a Guarantor holds the Note. 

If a Note is replaced pursuant to Section 2.07 hereof, it ceases to be outstanding unless the Trustee receives proof satisfactory to it
that the replaced Note is held by a protected purchaser (as defined in Section 8-303 of the Uniform Commercial Code). 
 If the
principal amount of any Note is considered paid under Section 4.01 hereof, it ceases to be outstanding and interest on it ceases to accrue. 

If the Paying Agent (other than an Issuer, a Subsidiary of Milacron, a Guarantor, or an Affiliate of any thereof) holds, on a Redemption Date
or maturity date, money sufficient to pay Notes (or portions thereof) payable on that date, then on and after that date such Notes (or portions thereof) shall be deemed to be no longer outstanding and shall cease to accrue interest. 

  
 -45- 








 Section 2.09. TREASURY
NOTES 
 In determining whether the Holders of the required principal amount of
Notes have concurred in any direction, waiver or consent, Notes owned by an Issuer, a Guarantor or by any Affiliate of an Issuer or a Guarantor, shall be considered as though not outstanding, except that for the purposes of determining whether the
Trustee shall be protected in relying on any such direction, waiver or consent, only Notes that a Responsible Officer of the Trustee knows are so owned shall be so disregarded. Notes so owned which have been pledged in good faith shall not be
disregarded if the pledgee establishes to the Trustee the pledgee’s right to deliver any such direction, waiver or consent with respect to the Notes and that the pledgee is not an Issuer, a Guarantor or any obligor upon the Notes or any
Affiliate of an Issuer, a Guarantor or of such other obligor. 
 Section 2.10. TEMPORARY
NOTES 
 Until certificates representing Notes are ready for delivery, the Issuers
may prepare and the Trustee, upon receipt of an Authentication Order, shall authenticate temporary Notes. Temporary Notes shall be substantially in the form of Definitive Notes but may have variations that the Issuers consider appropriate for
temporary Notes. Without unreasonable delay, the Issuers shall prepare and the Trustee shall authenticate Definitive Notes in exchange for temporary Notes. 

Holders and beneficial holders, as the case may be, of temporary Notes shall be entitled to all of the benefits accorded to Holders, or
beneficial holders, respectively, of Notes under this Indenture. 
 Section 2.11.
CANCELLATION 
 The Issuers at any time may deliver Notes to the Trustee
for cancellation. The Registrar and Paying Agent shall forward to the Trustee any Notes surrendered to them for registration of transfer, exchange or payment. The Trustee or, at the direction of the Trustee, the Registrar or the Paying Agent and no
one else shall cancel all Notes surrendered for registration of transfer, exchange, payment, replacement or cancellation and shall destroy cancelled Notes (subject to the record retention requirement of the Exchange Act and the Trustee).
Certification of the cancellation of all cancelled Notes shall be delivered to the Issuers upon written request. The Issuers may not issue new Notes to replace Notes that they have paid or that have been delivered to the Trustee for cancellation.

 Section 2.12. DEFAULTED INTEREST 

If the Issuers default in a payment of interest on the Notes, they shall pay the defaulted interest in any lawful manner plus, to the extent
lawful, interest payable on the defaulted interest, in each case at the rate provided in the Notes and in Section 4.01 hereof. The Issuers may pay the defaulted interest to the Persons who are Holders on a subsequent special record date. The
Issuers shall notify the Trustee in writing of the amount of defaulted interest proposed to be paid on each Note and the date of the proposed payment, and at the same time the Issuers shall deposit with the Trustee an amount of money equal to the
aggregate amount proposed to be paid in respect of such defaulted interest or shall make arrangements for such deposit prior to the date of the proposed payment, such money when deposited to be held in trust for the benefit of the Persons entitled
to such defaulted interest as provided in this Section 2.12. The Issuers shall fix or cause to be fixed any such special record date and payment date; provided that no such special record date shall be less than 10 days prior to the
related payment date for such defaulted interest. At least 15 days before any such special record date, the Issuers (or, upon the written request of the Issuers, the Trustee in the name and at the expense of the Issuers) shall mail or cause to be
mailed, first-class postage prepaid (or otherwise deliver in accordance with applicable DTC procedures), to each Holder, with a copy to the Trustee, a notice at his or her address as it appears in the Note Register that states the special record
date, the related payment date and the amount of such interest to be paid. 
 Subject to the foregoing provisions of this Section 2.12
and for greater certainty, each Note delivered under this Indenture upon registration of transfer of or in exchange for or in lieu of any other Note shall carry the rights to interest accrued and unpaid, and to accrue, which were carried by such
other Note. 

  
 -46- 








 Section 2.13. CUSIP/ISIN
NUMBERS 
 The Issuers in issuing the Notes may use
CUSIP and ISIN numbers (in each case, if then generally in use) and, if so, the Trustee shall use CUSIP and ISIN numbers in notices of redemption as a convenience to Holders; provided that any such notice may state that no representation is
made as to the correctness of such numbers either as printed on the Notes or as contained in any notice of redemption and that reliance may be placed only on the other identification numbers printed on the Notes, and any such redemption shall not be
affected by any defect in or omission of such numbers. The Issuers will as promptly as practicable notify the Trustee in writing of any change in the CUSIP and ISIN numbers. 

Section 2.14. CALCULATION
OF PRINCIPAL AMOUNT OF
SECURITIES 
 The aggregate principal amount of the Notes, at any date
of determination, shall be the principal amount of the Notes at such date of determination. With respect to any matter requiring consent, waiver, approval or other action of the Holders of a specified percentage of the principal amount of all the
Notes, such percentage shall be calculated, on the relevant date of determination, by dividing (a) the principal amount, as of such date of determination, of Notes, the Holders of which have so consented by (b) the aggregate principal
amount, as of such date of determination, of the Notes then outstanding, in each case, as determined in accordance with the preceding sentence, Section 2.08 and Section 2.09 of this Indenture. Any such calculation made pursuant to this
Section 2.14 shall be made by the Issuers and delivered to the Trustee pursuant to an Officer’s Certificate. 
 ARTICLE III

Section 3.01. NOTICES TO
TRUSTEE

Notes are listed or (b) on a pro rata basis to the extent practicable, or, if the pro rata basis is not practicable for any reason, by lot or by such other method the Trustee shall deem fair and appropriate. In the event of partial
redemption by lot, the particular Notes to be redeemed shall be selected, unless otherwise provided herein, not less than 30 nor more than 60 days prior to the Redemption Date by the Trustee from the outstanding Notes not previously called for
redemption. 
 The Trustee shall promptly notify the Issuers in writing of the Notes selected for redemption and, in the case of any Note
selected for partial redemption, the principal amount thereof to be redeemed. Notes and portions of Notes selected shall be in amounts of $2,000 or integral multiples of $1,000 in excess thereof; no Notes of less than $2,000 can be redeemed in part,
except that if all of the Notes of a Holder are to be redeemed, the entire outstanding amount of Notes held by such Holder, even if not a multiple of $1,000 shall be redeemed. Except as provided in the preceding sentence, provisions of this
Indenture that apply to Notes called for redemption also apply to portions of Notes called for redemption.

 Section 3.03. NOTICE OF
REDEMPTION 
 Subject to Section 3.09 hereof, the
Issuers shall deliver electronically or mail or cause to be mailed by first-class mail, postage prepaid (or otherwise deliver in accordance with applicable DTC procedures), notices of redemption at least 30 days but not more than 60 days before the
Redemption Date to each Holder of Notes to be redeemed at such Holder’s registered address appearing in the Note Register or otherwise in accordance with Applicable Procedures, except that redemption notices may be mailed more than 60 days
prior to a Redemption Date if the notice is issued in connection with Article VIII or Article XII hereof. 
 The notice shall
identify the Notes to be redeemed and shall state: 
 (a) the redemption date; 

(b) the appropriate method for calculation of the redemption price, but need not include the redemption price itself; the
actual redemption price shall be set forth in an Officer’s Certificate delivered to the Trustee no later than two (2) Business Days prior to the Redemption Date (or such shorter period as allowed by the Trustee); 

(c) if any Note is to be redeemed in part only, the portion of the principal amount of that Note that is to be redeemed and
that, after the Redemption Date upon surrender of such Note, a new Note or Notes in principal amount equal to the unredeemed portion of the original Note representing the same indebtedness to the extent not redeemed will be issued in the name of the
Holder of the Notes upon cancellation of the original Note; 
 (d) the name and address of the Paying Agent; 

(e) that Notes called for redemption must be surrendered to the Paying Agent to collect the redemption price; 

(f) that, unless the Issuers default in making such redemption payment, interest on Notes called for redemption ceases to
accrue on and after the Redemption Date;

pursuant to which the Notes called for redemption are being redeemed; 
 (h) the CUSIP and ISIN number, if any, printed on
the Notes being redeemed and that no representation is made as to the correctness or accuracy of any such CUSIP and ISIN number that is listed in such notice or printed on the Notes; and 

(i) if in connection with a redemption pursuant to Section 3.07 hereof, any condition to such redemption. 

At the Issuers’ request, the Trustee shall give the notice of redemption in the Issuers’ names and at their expense; provided
that the Issuers shall have delivered to the Trustee, at least two Business Days (or such shorter period as allowed by the Trustee) before notice of redemption is required to be mailed or caused to be mailed to Holders pursuant to this
Section 3.03 hereof, an Officer’s Certificate of the Issuer requesting that the Trustee give such notice and setting forth the information to be stated in such notice as provided in the preceding paragraph. 

The Issuer may provide in the notice of redemption that payment of the redemption price and performance of the Issuers’ obligations with
respect to such redemption or purchase may be performed by another Person. 

  
 -48- 








 Section 3.04. EFFECT OF
NOTICE OF REDEMPTION 
 Once notice of
redemption is given in accordance with Section 3.03 hereof, Notes called for redemption become irrevocably due and payable on the Redemption Date at the redemption price (except as provided for in Section 3.07 hereof). The notice, if given
in a manner herein provided, shall be conclusively presumed to have been given, whether or not the Holder receives such notice. In any case, failure to give such notice by mail or any defect in the notice to the Holder of any Note designated for
redemption in whole or in part shall not affect the validity of the proceedings for the redemption of any other Note. Subject to Section 3.05 hereof, on and after the Redemption Date, interest ceases to accrue on Notes or portions of Notes
called for redemption. 
 Section 3.05. DEPOSIT OF REDEMPTION
PRICE 
 (a) Prior to 11:00 a.m. (New York City time) on the
Redemption Date, the Issuers shall deposit with the Trustee or with the Paying Agent money sufficient to pay the redemption price of and accrued and unpaid interest on all Notes to be redeemed on that Redemption Date. The Trustee or the Paying Agent
shall promptly, and in any event within two Business Days after the Redemption Date, return to the Issuers any money deposited with the Trustee or the Paying Agent by the Issuers in excess of the amounts necessary to pay the redemption price of, and
accrued and unpaid interest on, all Notes to be redeemed. 
 (b) If the Issuers comply with the provisions of the preceding paragraph (a),
on and after the Redemption Date, interest shall cease to accrue on the applicable series of Notes or the portions of Notes called for redemption, whether or not such Notes are presented for payment. If a Note is redeemed on or after a Record Date
but on or prior to the related Interest Payment Date, then any accrued and unpaid interest to the Redemption Date shall be paid to the Person in whose name such Note was registered at the close of business on such Record Date. If any Note called for
redemption shall not be so paid upon surrender for redemption because of the failure of the Issuers to comply with the preceding paragraph, interest shall be paid on the unpaid principal, from the Redemption Date until such principal is paid, and to
the extent lawful on any interest accrued to the Redemption Date not paid on such unpaid principal, in each case at the rate provided in the Notes and in Section 4.01 hereof. 

Section 3.06. NOTES REDEEMED IN
PART 
 Upon surrender of a Note that is redeemed in part, the Issuers
shall issue and the Trustee shall authenticate for the Holder at the expense of the Issuers a new Note equal in principal amount to the unredeemed portion of the Note surrendered representing the same indebtedness to the extent not redeemed;
provided that each new Note will be in a principal amount of $2,000 or an integral multiple of $1,000 in excess thereof. It is understood that, notwithstanding anything in this Indenture to the contrary, only an Authentication Order and not an
Opinion of Counsel or Officer’s Certificate of the Issuers is required for the Trustee to authenticate such new Note. 

Section 3.07. OPTIONAL
REDEMPTION 
 (a) The Issuers may redeem the Notes in accordance with
the provisions of the applicable Note, as set forth in Exhibit A. The Trustee shall have no duty to calculate or verify the calculation of any Applicable Premium. Notwithstanding anything to the contrary contained herein or in the applicable Note,
notice of any redemption may, at the Issuers’ discretion, be subject to one or more conditions precedent, including, but not limited to, completion of an Equity Offering or other corporate transaction.

REDEMPTION

the Issuers shall not be required to make mandatory redemption or sinking fund payments with respect to, or offer to purchase, the Notes.

 Section 3.09. OFFER TO
PURCHASE 
 (a) In the event that, pursuant to Section 4.10
hereof, the Issuers shall be required to commence an Asset Sale Offer, they shall follow the procedures specified below. 
 (b) The Asset
Sale Offer shall remain open for a period of 20 Business Days following its commencement and no longer, except to the extent that a longer period is required by applicable law (the “Offer Period”). No later than five Business Days
after the termination of the Offer Period (the “Purchase Date”), the Issuers shall apply all Excess Proceeds (the “Offer Amount”) to the purchase of Notes and, if required, other pari passu Indebtedness (on a pro
rata basis, if applicable), or, if less than the Offer Amount has been tendered, all Notes and other pari passu Indebtedness tendered in response to the Asset Sale Offer. Payment for any Notes so purchased shall be made in the same manner as
interest payments are made. 
 (c) If the Purchase Date is on or after a Record Date and on or before the related Interest Payment Date, any
accrued and unpaid interest, up to but excluding the Purchase Date, shall be paid to the Person in whose name a Note is registered at the close of business on such Record Date, and no additional interest shall be payable to Holders who tender Notes
pursuant to the Asset Sale Offer. 
 (d) Upon the commencement of an Asset Sale Offer, the Issuers shall send, by first-class mail, postage
prepaid (or otherwise deliver in accordance with applicable DTC procedures), a notice to each of the Holders, with a copy to the Trustee. The notice shall contain all instructions and materials necessary to enable such Holders to tender Notes
pursuant to the Asset Sale Offer. The Asset Sale Offer shall be made to all Holders and all holders of other Indebtedness that is pari passu with the Notes and is also unsecured containing provisions similar to those set forth in this Indenture to
purchase or redeem with the proceeds of sales of assets. The notice, which shall govern the terms of the Asset Sale Offer, shall state: 

(i) that the Asset Sale Offer is being made pursuant to this Section 3.09 and Section 4.10 hereof and the length of
time the Asset Sale Offer shall remain open; 
 (ii) the Offer Amount, the purchase price and the Purchase Date; 

(iii) that any Note not tendered or accepted for payment shall continue to accrue interest; 

(iv) that, unless the Issuers default in making such payment, any Note accepted for payment pursuant to the Asset Sale Offer
shall cease to accrue interest on and after the Purchase Date;

 -61- 








 (b) make loans or advances to Milacron or any of the Restricted Subsidiaries; or

contemplation thereof), which encumbrance or restriction is not applicable to any Person, or the properties or assets of any Person, other than the Person and its Subsidiaries, or the property or assets of the Person and its Subsidiaries, so
acquired; provided that for purposes of this subsection (d)(v), if a Person other than Milacron is the Successor Company with respect thereto, any Subsidiary thereof or agreement or instrument of such Person or any such Subsidiary shall be
deemed acquired or assumed, as the case may be, by Milacron or a Restricted Subsidiary, as the case may be, when such Person becomes such Successor Company; 

(vi) contracts for the sale of assets, including customary restrictions with respect to a Subsidiary of (i) Milacron or

 (xiv) any
encumbrance or restriction arising pursuant to an agreement or instrument relating to any Indebtedness permitted to be incurred pursuant to the covenants described in Section 4.09 (A) if the encumbrances and restrictions contained in any
such agreement or instrument taken as a whole are not materially less favorable to the Holders than the encumbrances and restrictions contained in the ABL Credit Agreement, the Term Loan Credit Agreement, the Existing Foreign Facilities or this
Indenture as of the Issue Date (in each case, as determined in good faith by Milacron) or (B) any such encumbrance or restriction contained in such Indebtedness does not prohibit (except upon a default or an event of default thereunder) the
payment of dividends in an amount sufficient, as determined by the Board of Directors of Milacron in good faith, to make scheduled payments of cash interest on the Notes when due; or 

(xv) any encumbrances or restrictions of the type referred to in subsections (a), (b) and (c) above imposed by any
amendments, modifications, restatements, amendments and restatements, extensions, restructurings, renewals, increases, supplements, refundings, replacements or refinancings of the contracts, instruments or obligations referred to in subsections
(d)(i) through (xiv) above; provided that such amendments, modifications, restatements, amendments and restatements, extensions, restructurings, renewals, increases, supplements, refundings, replacements or refinancings are, in the good
faith judgment of Milacron, no more materially restrictive with respect to such encumbrance and other restrictions taken as a whole than those prior to such amendment, modification, restatement, renewal, increase, supplement, refunding, replacement
or refinancing. 
 (e) For purposes of determining compliance with this Section 4.08, (1) the priority of any
Preferred Stock in receiving dividends or liquidating distributions prior to dividends or liquidating distributions being paid on common shares shall not be deemed a restriction on the ability to make distributions on Capital Stock and (2) the
subordination of (or remedy bars in respect of) loans or advances made to Milacron or a Restricted Subsidiary to other Indebtedness incurred by Milacron or any such Restricted Subsidiary shall not be deemed a restriction on the ability to make loans
or advances.

 (a) Milacron will not, and will not permit any of the Restricted Subsidiaries to, directly or indirectly, create, incur, issue,
assume, guarantee or otherwise become directly or indirectly liable, contingently or otherwise (collectively, “incur” and collectively, an “incurrence”) with respect to any Indebtedness (including Acquired
Indebtedness) and Milacron will not issue any shares of Disqualified Stock and Milacron will not permit any Restricted Subsidiary to issue any shares of Disqualified Stock or Preferred Stock; provided, however, that Milacron may incur
Indebtedness (including Acquired Indebtedness), Milacron may issue shares of Disqualified Stock, and any Restricted Subsidiary or the Co-Issuer may incur Indebtedness (including Acquired Indebtedness), issue shares of Disqualified Stock and issue
shares of Preferred Stock, if the Fixed Charge Coverage Ratio on a consolidated basis for Milacron and its Restricted Subsidiaries for the most recently ended four fiscal quarters for which internal financial statements are available immediately
preceding the date on which such additional Indebtedness is incurred or such Disqualified Stock or Preferred Stock is issued would have been at least 2.0 to 1.0, determined on a pro forma basis (including a pro forma application of the net proceeds
therefrom), as if the additional Indebtedness had been incurred, or the Disqualified Stock or Preferred Stock had been issued, as the case may be, and the application of proceeds therefrom had occurred at the beginning of such four quarter period;
provided further that Restricted Subsidiaries (other than the Co-Issuer) that are not Guarantors may not incur

therefrom), the aggregate amount of Indebtedness or Disqualified Stock or Preferred Stock of Restricted Subsidiaries (other than the Co-Issuer) that are not Guarantors outstanding pursuant to this paragraph and clause (x) of
Section 4.09(b)(xiii) exceeds the greater of (x) $50.0 million and (y) 3.0% of Total Assets.

Preferred Stock incurred and outstanding under this clause (iv), not to exceed at any time outstanding the greater of $50.0 million and 3.0% of Total Assets, including any refinancing pursuant to clause (xii) below; so long as such Indebtedness
(other than Refinancing Indebtedness) exists at the date of such purchase, lease, construction, repair, replacement or improvement of the relevant property or equipment, or is created within 270 days thereafter; 

(v) Indebtedness incurred by Milacron or any Restricted Subsidiary constituting reimbursement obligations with respect to

Indebtedness (except to Milacron or another Restricted Subsidiary or any pledge of such Indebtedness constituting a Permitted Lien) shall be deemed, in each case, to be an incurrence of such Indebtedness not permitted by this clause (vii); 

(viii) shares of Preferred Stock of a Restricted Subsidiary issued to Milacron or another Restricted Subsidiary,
provided that any subsequent issuance or transfer of any Capital Stock or any other event which results in any such Restricted Subsidiary ceasing to be a Restricted Subsidiary or any other subsequent transfer of any such shares of Preferred

the principal amount and liquidation preference of all other Indebtedness, Disqualified Stock and Preferred Stock then outstanding and incurred pursuant to this subsection (xi)(b), does not at any one time outstanding exceed $100.0 million (it being
understood that any Indebtedness, Disqualified Stock or Preferred Stock incurred pursuant to this subsection (xi)(b) shall cease to be deemed incurred or outstanding for purposes of this subsection (xi)(b) but shall be deemed incurred for the
purposes of Section 4.09(a) from and after the first date on which Milacron or such Restricted Subsidiary could have incurred such Indebtedness, Disqualified Stock or Preferred Stock under Section 4.09(a) without reliance on this
subsection (xi)(b));

 (c) For purposes of determining compliance with this covenant: 

(i) in the event that an item of Indebtedness, Disqualified Stock or Preferred Stock (or any portion thereof) meets the
criteria of more than one of the categories of permitted Indebtedness, Disqualified Stock or Preferred Stock described in Sections 4.09(b)(i) through 4.09(b)(xxiv) or is entitled to be incurred pursuant to Section 4.09(a), Milacron, in its sole
discretion, may classify or reclassify, or later divide, classify or reclassify, such item of Indebtedness, Disqualified Stock or Preferred Stock (or any portion thereof) and will only be required to include the amount and type of such Indebtedness,
Disqualified Stock or Preferred Stock in one of the above clauses; provided that all Indebtedness outstanding under the ABL Credit Agreement and the Term Loan Credit Agreement on the Issue Date will be treated as incurred on the Issue Date
under Section 4.09(b)(i) and may not later be reclassified; 
 (ii) at the time of incurrence or reclassification,
Milacron will be entitled to divide and classify an item of Indebtedness in more than one of the types of Indebtedness described in Section 4.09(a) or (b) and shall be entitled to treat a portion of such Indebtedness as having been
incurred under Section 4.09(a) and thereafter the remainder of such Indebtedness having been incurred under Section 4.09(b); and 

(iii) the amount of any Indebtedness that is issued at a price that is less than the principal amount thereof shall be equal to
the amount of liability in respect thereof determined in accordance with GAAP. 
 (d) Accrual of interest or dividend, the accretion of
accreted value, the accretion of original issue discount or liquidation preference or the amortization of original discount and increases in the amount of Indebtedness outstanding solely as a result of fluctuations in the exchange rate of currencies
and the payment of interest or dividends in the form of additional Indebtedness, Disqualified Stock or Preferred Stock, as applicable, will not be deemed in each case to be an incurrence of Indebtedness, Disqualified Stock or Preferred Stock for
purposes of this covenant. Guarantees of, or obligations in respect of undrawn letters of credit relating to, Indebtedness that is otherwise included in the determination of a particular amount of Indebtedness shall not be included in the
determination of such amount of Indebtedness; provided that the incurrence of the Indebtedness represented by such guarantee or letter of credit, as the case may be, was in compliance with this covenant. 

(e) For purposes of determining compliance with any U.S. dollar-denominated restriction on the incurrence of Indebtedness, the U.S.
dollar-equivalent principal amount of Indebtedness denominated in a foreign currency shall be calculated based on the relevant currency exchange rate in effect on the date such Indebtedness was incurred, in the case of term debt, or first committed,
in the case of revolving credit debt; provided that if such Indebtedness is incurred to refinance other Indebtedness denominated in a foreign currency, and such refinancing would cause the applicable U.S. dollar-denominated restriction to be
exceeded if calculated at the relevant currency exchange rate in effect on the date of such refinancing, such U.S. dollar-denominated restriction shall be deemed not to have been exceeded so long as the principal amount of such refinancing
Indebtedness does not exceed the principal amount of such Indebtedness being refinanced. 
 (f) The principal amount of any Indebtedness
incurred to refinance other Indebtedness, if incurred in a different currency from the Indebtedness being refinanced, shall be calculated based on the currency exchange rate applicable to the currencies in which such respective Indebtedness is
denominated that is in effect on the date of such refinancing. 
 (g) Milacron will not, and will not permit any Guarantor to, directly or
indirectly, incur any Indebtedness (including Acquired Indebtedness) that is subordinated or junior in right of payment to any Indebtedness of Milacron or such Guarantor, as the case may be, unless such Indebtedness is expressly subordinated in
right of payment to the Notes or such Guarantor’s Guarantee to the extent and in the same manner as such Indebtedness is subordinated to other Indebtedness of Milacron or such Guarantor, as the case may be. For purposes of this Indenture
(i) unsecured Indebtedness will not be treated as subordinated or junior to Secured Indebtedness merely because it is unsecured or (ii) Senior Indebtedness will not be treated as subordinated or junior to any other Senior Indebtedness
merely because it has a junior priority with respect to the same collateral.

 Section 4.10. ASSET
SALES 
 (I) (a) Milacron will not, and will not permit any Restricted
Subsidiary to consummate, directly or indirectly, an Asset Sale, unless: 
 (i) Milacron or such Restricted Subsidiary, as
the case may be, receives consideration at the time of such Asset Sale at least equal to the fair market value (as determined in good faith by Milacron) of the assets sold or otherwise disposed of; and 

(ii) except in the case of a Permitted Asset Swap, at least 75% of the consideration therefor received by Milacron or such
Restricted Subsidiary, as the case may be, is in the form of cash or Cash Equivalents (as defined in (II) below). 
 (b) Within 365 days
after the receipt of any Net Proceeds of any Asset Sale covered by Section 4.10(I)(a), Milacron or such Restricted Subsidiary, at its option, may apply the Net Proceeds from such Asset Sale: 

(i) to permanently reduce (i) Obligations under Senior Indebtedness that is secured by a Lien, which Lien is permitted by
Section 4.12 hereof, and to correspondingly reduce commitments with respect thereto or (ii) Obligations under unsecured Senior Indebtedness of the Issuers or a Guarantor (and to correspondingly reduce commitments with respect thereto);
provided that if any such unsecured Senior Indebtedness other than the Notes is reduced with the Net Proceeds of any Asset Sale, the Issuers shall equally and ratably reduce Obligations under the Notes as provided under Section 3.07
through open market purchases (to the extent such purchases are at or above 100% of the principal amount thereof) or by making an offer (in accordance with the procedures set forth below for any Asset Sale Offer) to all Holders to purchase their
Notes at 100% of the principal amount thereof, plus accrued but unpaid interest, if any; 
 (ii) to make (A) an
Investment in any one or more businesses, provided that such Investment in any business is in the form of the acquisition of Capital Stock and results in Milacron or a Restricted Subsidiary, as the case may be, owning an amount of the Capital
Stock of such business such that it constitutes a Restricted Subsidiary, (B) capital expenditures or (C) acquisitions of other assets that are, in each of (A), (B) and (C), used or useful in a Similar Business, or replace the
businesses, properties and/or assets that are the subject of such Asset Sale; or 
 (iii) to permanently reduce Indebtedness
of a Restricted Subsidiary that is not a Guarantor, other than Indebtedness owed to an Issuer, a Guarantor or a Restricted Subsidiary; 
 provided
that, in the case of subsection (ii) above, a binding commitment shall be treated as a permitted application of the Net Proceeds from the date of such commitment so long as Milacron or such Restricted Subsidiary enters into such commitment with
the good faith expectation that such Net Proceeds will be applied to satisfy such commitment within 180 days of such commitment (an “Acceptable Commitment”) and, in the event any Acceptable Commitment is later cancelled or
terminated for any reason before the Net Proceeds are applied in connection therewith, then such Net Proceeds shall constitute Excess Proceeds. 

(c) Any Net Proceeds from the Asset Sales covered by this clause (I) that are not invested or applied as provided and within the time
period set forth in Section 4.10(I)(b) shall be deemed to constitute “Excess Proceeds.” When the aggregate amount of Excess Proceeds exceeds $25.0 million, Milacron shall make an offer (an “Asset Sale Offer”)
to all Holders and all holders of other Indebtedness that is pari passu with the Notes and is also unsecured containing provisions similar to those set forth in this Indenture to purchase or redeem with the proceeds of sales of assets to purchase
the maximum aggregate principal amount of the Notes and other such pari passu and unsecured Indebtedness that may be purchased out of the Excess Proceeds. The offer price in any Asset Sale Offer will be equal to 100% of the principal amount thereof,
plus accrued and unpaid interest, if any, to, but not including, the date fixed for the closing of such offer, in accordance with the procedures set forth in this Indenture; provided that no Notes of $2,000 or less can be repurchased in part.
Milacron will commence an Asset Sale Offer with respect to Excess Proceeds within ten Business Days after the date that Excess Proceeds exceed $25.0 million by giving the notice required pursuant to the terms of this Indenture, with a copy to the
Trustee. 

  
 -69- 








 (d) To the extent that the aggregate principal amount of Notes and other pari passu Indebtedness
tendered pursuant to an Asset Sale Offer is less than the Excess Proceeds, Milacron may use any remaining Excess Proceeds for general corporate purposes, subject to other covenants contained in this Indenture. If the aggregate principal amount of
Notes and other pari passu Indebtedness tendered pursuant to such Asset Sale Offer exceeds the amount of Excess Proceeds, the Trustee shall select the Notes to be purchased on a pro rata basis based on the principal amount of the Notes tendered.
Upon completion of any such Asset Sale Offer, the amount of Excess Proceeds shall be reset at zero (or, in the case of Notes in global form, the Trustee will select Notes for repurchase based on DTC’s method that most nearly approximates a pro
rata selection or by such other method that the Trustee shall deem fair and appropriate). 
 (II) For purposes of this Section 4.10, the
following are deemed to be cash or Cash Equivalents: 
 (a) any liabilities (as shown on Milacron’s, or such Restricted
Subsidiary’s, most recent balance sheet or in the notes thereto or if incurred or accrued subsequent to the date of such balance sheet, such liabilities that would have been shown on Milacron or such Restricted Subsidiary’s balance sheet
or in the footnotes thereto) of Milacron or any Restricted Subsidiary, other than liabilities that are by their terms subordinated to the Notes, that are assumed by the transferee of any such assets and for which Milacron and all Restricted
Subsidiaries have been validly released by all creditors in writing; 
 (b) any securities received by Milacron or such
Restricted Subsidiary from such transferee that are converted by Milacron or such Restricted Subsidiary into cash (to the extent of the cash received) within 180 days following the closing of such Asset Sale; and 

(c) any Designated Non-cash Consideration received by Milacron or such Restricted Subsidiary in such Asset Sale having an
aggregate fair market value, taken together with all other Designated Non-cash Consideration received pursuant to this clause (iii) that is at that time outstanding, not to exceed the greater of (x) $50.0 million and (y) 3.0% of Total
Assets at the time of the receipt of such Designated Non-cash Consideration, with the fair market value of each item of Designated Non-cash Consideration being measured at the time received and without giving effect to subsequent changes in value.

 (III) Milacron will comply with the requirements of Rule 14e-1 under the Exchange Act and any other securities laws and regulations
thereunder to the extent such laws or regulations are applicable in connection with the repurchase of Notes pursuant to an Asset Sale Offer. To the extent that the provisions of any securities laws or regulations conflict with the provisions of this
Indenture, Milacron will comply with the applicable securities laws and regulations and shall not be deemed to have breached its obligations described in this Section 4.10 by virtue of such compliance. 

Section 4.11. AFFILIATE TRANSACTIONS 

(a) Milacron will not, and will not permit any of the Restricted Subsidiaries to, make any payment to, or sell, lease, transfer or otherwise
dispose of any of its properties or assets to, or purchase any property or assets from, or enter into or make or amend any transaction, contract, agreement, understanding, loan, advance or guarantee with, or for the benefit of, any Affiliate of
Milacron (each of the foregoing, an “Affiliate Transaction”) involving aggregate payments or consideration in excess of $10.0 million, unless: 

(i) such Affiliate Transaction is on terms that are not materially less favorable to Milacron or the relevant Restricted
Subsidiary than those that would have been obtained in a comparable transaction by Milacron or such Restricted Subsidiary with an unrelated Person; and 

  
 -70- 








 (ii) Milacron delivers to the Trustee with respect to any Affiliate Transaction
or series of related Affiliate Transactions involving aggregate payments or consideration in excess of $25.0 million, a Board Resolution adopted by the majority of the Board of Directors of Milacron approving such Affiliate Transaction and set forth
in an Officer’s Certificate certifying that such Affiliate Transaction complies with clause (i) above. 
 (b) The provisions of
Section 4.11(a) will not apply to: 
 (i) transactions between or among Milacron or any of the Restricted Subsidiaries
(or an entity that becomes a Restricted Subsidiary as a result of such transaction) or between or among Restricted Subsidiaries; 

(ii) Restricted Payments permitted by the provisions of this Indenture described above under Section 4.07 and Permitted
Investments; 
 (iii) the payment of management, consulting, monitoring, transaction, advisory and termination fees and
related expenses and indemnities, directly or indirectly, to the Investors pursuant to the Financial Advisory Agreement (plus any unpaid management, consulting, monitoring, transaction, advisory and termination fees and related expenses and
indemnities accrued in any prior year); 
 (iv) the payment of reasonable and customary fees paid to, and indemnities
provided on behalf of, officers, directors, employees, members of management or consultants of Milacron, any of Milacron’s direct or indirect parent companies or any of the Restricted Subsidiaries; 

(v) transactions in which Milacron or any of the Restricted Subsidiaries, as the case may be, delivers to the Trustee a letter
from an Independent Financial Advisor stating that such transaction is fair to Milacron or such Restricted Subsidiary from a financial point of view or stating that the terms are not materially less favorable to Milacron or the relevant Restricted
Subsidiary than those that would have been obtained in a comparable transaction by Milacron or such Restricted Subsidiary with an unrelated Person; 

(vi) any agreement as in effect as of the Issue Date (other than the Financial Advisory Agreement), or any amendment thereto
(so long as any such amendment is not disadvantageous in any material respect to the Holders when taken as a whole as compared to the applicable agreement as in effect on the Issue Date); 

(vii) the existence of, or the performance by Milacron or any of the Restricted Subsidiaries of its obligations under the terms
of, any stockholders agreement, principal investors agreement (including any registration rights agreement or purchase agreement related thereto) to which it was a party as of the Issue Date and any similar agreements which it may enter into
thereafter; provided, however, that the existence of, or the performance by Milacron or any of the Restricted Subsidiaries of obligations under any future amendment to any such existing agreement or under any similar agreement entered
into after the Issue Date shall only be permitted by this subsection (b)(vii) to the extent that the terms of any such amendment or new agreement are not otherwise disadvantageous in any material respect to the Holders when taken as a whole; 

(viii) the Mold-Masters Acquisition Transactions and the payment of all fees and expenses related to the Mold-Masters
Acquisition Transactions; 
 (ix) transactions with customers, clients, suppliers, or purchasers or sellers of goods or
services, in each case in the ordinary course of business and otherwise in compliance with the terms of this Indenture which are fair to Milacron and the Restricted Subsidiaries, in the reasonable determination of the Board of Directors of Milacron
or the senior management thereof, or are on terms at least as favorable as might reasonably have been obtained at such time from an unaffiliated party; 

(x) the issuance of Equity Interests (other than Disqualified Stock) by Milacron or a Restricted Subsidiary to any Person; 


  
 -71- 








 (xi) sales of accounts receivable, or participations therein, in connection with
any Receivables Facility; 
 (xii) payments by Milacron or any of the Restricted Subsidiaries to any of the Investors made
for any financial advisory, financing, underwriting or placement services or in respect of other investment banking activities, including, without limitation, in connection with acquisitions or divestitures which payments are approved by a majority
of the Board of Directors of Milacron in good faith; 
 (xiii) payments, loans (or cancellation of loans) or advances to
directors, officers, employees, members of management or consultants (or the estate, heirs, family members, spouse, former spouse, domestic partner or former domestic partner of any of the foregoing) of Milacron, any of the direct or indirect parent
companies or any of its Subsidiaries and employment agreements, severance arrangements, stock option plans and other similar arrangements with such employees, members of management or consultants (or the estate, heirs, family members, spouse, former
spouse, domestic partner or former domestic partner of any of the foregoing) which, in each case, are approved by a majority of the Board of Directors of Milacron in good faith; 

(xiv) investments by the Investors in debt securities of Milacron or any of the Restricted Subsidiaries (and payment of
reasonable out-of-pocket expenses incurred by the Investors in connection therewith); 
 (xv) the issuances of securities or
other payments, awards or grants in cash, securities or otherwise pursuant to, or the funding of, employment arrangements, stock option and stock ownership plans or similar employee benefit plans approved by the Board of Directors of Milacron or any

(xviii) transactions with joint ventures or Unrestricted Subsidiaries entered into in the ordinary course of business which are
fair to Milacron and the Restricted Subsidiaries, in the reasonable determination of the Board of Directors of Milacron or the senior management thereof, or are on terms at least as favorable as might reasonably have been obtained at such time from
an unaffiliated party. 
 Section 4.12. LIENS 

(a) Milacron will not, and will not permit any Restricted Subsidiary to, directly or indirectly, create, incur, assume or suffer to exist any
Lien (each, a “Subject Lien”) that secures obligations under any Indebtedness, on any asset or property of Milacron or any Restricted Subsidiary, or any income or profits therefrom, or assign or convey any right to receive income
therefrom, except Permitted Liens, unless: 
 (i) in the case of Subject Liens securing subordinated Indebtedness, the Notes
and related Guarantees are secured by a Lien on such asset or property that is senior in priority to such Subject Lien; and 

(ii) in all other cases, the Notes or the Guarantees are equally and ratably secured. 

(b) Any Lien created for the benefit of the Holders pursuant to Section 4.12(a)(i) or (ii) shall provide by its terms that such Lien
shall automatically and unconditionally be released and discharged upon the release and discharge of the initial Lien that gave rise to the obligation to secure the Notes. 

  
 -72- 








 Section 4.13. CORPORATE
EXISTENCE 
 Subject to Article V hereof, the Issuers shall do or cause to be
done all things necessary to preserve and keep in full force and effect (i) limited liability company existence with respect to Milacron and corporate existence with respect to the Co-Issuer, and the corporate, partnership, limited liability
company or other existence of each Restricted Subsidiary, in accordance with the respective organizational documents (as the same may be amended from time to time) of the Issuers or any such Restricted Subsidiary and (ii) the material rights
(charter and statutory), licenses and franchises of the Issuers and the Restricted Subsidiaries; provided, however, that the Issuers shall not be required to preserve any such right, license or franchise, or the corporate, partnership,
limited liability company or other existence of any Restricted Subsidiary, if the Board of Directors of Milacron shall determine that the preservation thereof is no longer desirable in the conduct of the business of Milacron and the Restricted
Subsidiaries, taken as a whole. 
 Section 4.14. REPURCHASE AT THE
OPTION OF HOLDERS UPON A CHANGE OF CONTROL 

(a) If a Change of Control occurs, unless the Issuers have previously or concurrently given a redemption notice with respect to all the
outstanding Notes as described under Section 3.07 hereof, the Issuers shall make an offer to purchase all of the Notes pursuant to the offer described below (the “Change of Control Offer”) at a price in cash (the
“Change of Control Payment”) equal to 101% of the aggregate principal amount thereof plus accrued and unpaid interest to, but not including, the date of purchase, subject to the right of Holders of the Notes of record on the
relevant Record Date to receive interest due on the relevant Interest Payment Date. Within 30 days following any Change of Control, the Issuers shall send notice of such Change of Control Offer electronically or by first-class mail (or otherwise
deliver in accordance with applicable DTC procedures), with a copy to the Trustee, to each Holder of Notes to the address of such Holder appearing in the Note Register or otherwise in accordance with Applicable Procedures, with the following
information: 
 (i) that a Change of Control Offer is being made pursuant to this Section 4.14 and that all Notes
properly tendered pursuant to such Change of Control Offer will be accepted for payment by the Issuers; 
 (ii) the purchase
price and the purchase date, which will be no earlier than 30 days nor later than 60 days from the date such notice is given (the “Change of Control Payment Date”); 

(iii) that any Note not properly tendered will remain outstanding and continue to accrue interest; 

(iv) that unless the Issuers default in the payment of the Change of Control Payment, all Notes accepted for payment pursuant
to the Change of Control Offer will cease to accrue interest on the Change of Control Payment Date; 
 (v) that Holders
electing to have any Notes purchased pursuant to a Change of Control Offer will be required to surrender such Notes, with the form entitled “Option of Holder to Elect Purchase” on the reverse of such Notes completed, to the Paying Agent
specified in the notice at the address specified in the notice prior to the close of business on the third Business Day preceding the Change of Control Payment Date; 

(vi) that Holders will be entitled to withdraw their tendered Notes and their election to require the Issuers to purchase such
Notes, provided that the Paying Agent receives, not later than the close of business on the fifth Business Day preceding the Change of Control Payment Date, a facsimile transmission or letter setting forth the name of the Holder of the Notes,
the principal amount of such Notes tendered for purchase, and a statement that such Holder is withdrawing its tendered Notes and its election to have such Notes purchased; 

  
 -73- 








 (vii) that the Holders whose Notes are being repurchased only in part will be
issued new Notes equal in principal amount to the unpurchased portion of the Notes surrendered (the unpurchased portion of the Notes must be equal to a minimum of $2,000 or an integral multiple of $1,000 in principal amount); 

(viii) the other instructions, as determined by the Issuers, consistent with the covenant described hereunder, that a Holder
must follow; and 
 (ix) if such notice is sent prior to the occurrence of a Change of Control, stating that the Change of
Control Offer is conditional upon the occurrence of such Change of Control. 
 The notice, if sent in a manner herein provided, shall be
conclusively presumed to have been given, whether or not the Holder receives such notice. If (a) the notice is sent in a manner herein provided and (b) any Holder fails to receive such notice or a Holder receives such notice but it is
defective, such Holder’s failure to receive such notice or such defect shall not affect the validity of the proceedings for the purchase of the Notes as to all other Holders that properly received such notice without defect. The Issuers shall
comply with the requirements of Rule 14e-1 under the Exchange Act and any other securities laws and regulations thereunder to the extent such laws or regulations are applicable in connection with the repurchase of Notes pursuant to a Change of
Control Offer. To the extent that the provisions of any securities laws or regulations conflict with the provisions of this Indenture, the Issuers will comply with the applicable securities laws and regulations and shall not be deemed to have
breached their obligations described in this Indenture by virtue thereof. 
 (b) On the Change of Control Payment Date, the Issuers shall,
to the extent permitted by law, 
 (i) accept for payment all Notes or portions thereof properly tendered pursuant to
the Change of Control Offer, 
 (ii) deposit with the Paying Agent an amount equal to the aggregate Change of Control Payment
in respect of all Notes or portions thereof so tendered, and 
 (iii) deliver, or cause to be delivered, to the Trustee for
cancellation the Notes so accepted together with an Officer’s Certificate to the Trustee stating that such Notes or portions thereof have been tendered to and purchased by the Issuers. 

(c) The Issuers shall not be required to make a Change of Control Offer following a Change of Control if a third party makes the Change of
Control Offer in the manner, at the times and otherwise in compliance with the requirements set forth in this Indenture applicable to a Change of Control Offer made by the Issuers and purchases all Notes validly tendered and not withdrawn under such
Change of Control Offer. Notwithstanding anything to the contrary herein, a Change of Control Offer may be made in advance of a Change of Control, conditional upon such Change of Control, if a definitive agreement is in place for the Change of
Control at the time of making of the Change of Control Offer. 
 (d) Other than as specifically provided in this Section 4.14, any
purchase pursuant to this Section 4.14 shall be made pursuant to the provisions of Sections 3.02, 3.05 and 3.06 hereof, and references therein to “redeem,” “redemption” and similar words shall be deemed to refer to
“purchase,” “repurchase” and similar words, as applicable. 
 Section 4.15.
GUARANTEES OF INDEBTEDNESS BY RESTRICTED SUBSIDIARIES 

Milacron will not permit any Restricted Subsidiary that is a Wholly-Owned Subsidiary of Milacron (and non-Wholly Owned Subsidiaries if such
non-Wholly Owned Subsidiaries guarantee other capital markets debt securities of Milacron or a Guarantor), other than a Guarantor or a Foreign Subsidiary or a special purpose Restricted Subsidiary formed in connection with a Receivables Facility, to
guarantee the payment of or become an obligor under any Indebtedness of Milacron, the Co-Issuer or any other Guarantor unless such Restricted Subsidiary within 30 days executes and delivers a supplemental indenture to this Indenture providing for a


  
 -74- 








 
Guarantee by such Restricted Subsidiary, except that with respect to a guarantee of Indebtedness of Milacron or any Guarantor: 

(a) if the Notes or such Guarantor’s Guarantee are subordinated in right of payment to such Indebtedness, the Guarantee
under the supplemental indenture shall be subordinated to such Restricted Subsidiary’s guarantee with respect to such Indebtedness substantially to the same extent as the Notes are subordinated to such Indebtedness; and 

(b) if such Indebtedness is by its express terms subordinated in right of payment to the Notes or such Guarantor’s
Guarantee, any such guarantee by such Restricted Subsidiary with respect to such Indebtedness shall be subordinated in right of payment to such Guarantee substantially to the same extent as such Indebtedness is subordinated to the Notes or such
Guarantor’s Guarantee; provided that this sentence shall not be applicable to any guarantee of any Restricted Subsidiary that existed at the time such Person became a Restricted Subsidiary and was not incurred in connection with, or in
contemplation of, such Person becoming a Restricted Subsidiary. 
 Section 4.16. RESTRICTIONS
ON ACTIVITIES OF THE CO-ISSUER 

The Co-Issuer shall not hold any material assets, become liable for any material obligations or engage in any business activities or
operations; provided that the Co-Issuer may (i) be a co-obligor with respect to Indebtedness (including, for the avoidance of doubt, the Notes and the Secured Notes) if Milacron is a primary obligor on such Indebtedness, the net proceeds
of such Indebtedness are received by Milacron or one or more of the Restricted Subsidiaries and such Indebtedness is otherwise permitted to be incurred under this Indenture and (ii) guarantee any Obligations under the ABL Credit Agreement, the
Term Loan Credit Agreement or any other Credit Facilities Debt. 
 Section 4.17. MAINTENANCE
OF PROPERTIES 
 The Issuers shall, and shall cause each of
the Restricted Subsidiaries to at all times maintain, preserve and protect all property material to the conduct of their business and keep such property in good repair, working order and condition, except as would not have a material adverse effect
on the ability of the Issuers and the Guarantors to satisfy their obligations under this Indenture and the Notes.

right and power of such Issuer or Guarantor, as applicable, under this Indenture with the same effect as if such successor Person had been named as an Issuer or a Guarantor, as applicable, herein; provided that the predecessor Issuer shall

 ARTICLE VI  

DEFAULTS AND REMEDIES 

Section 6.01. EVENTS OF DEFAULT

on the Notes; 
 (b) default for 30 days or more in the payment when due of interest on or with respect to the Notes; 

(c) failure by the Issuers or any Restricted Subsidiary for 60 days after receipt of written notice given by the Trustee or the

contained in this Indenture or the Notes; 
 (d) default under any mortgage, indenture or instrument under which there is
issued or by which there is secured or evidenced any Indebtedness for money borrowed by Milacron or any of the Restricted Subsidiaries or the payment of which is guaranteed by Milacron or any of the Restricted Subsidiaries, other than Indebtedness
owed to Milacron or a Restricted Subsidiary, whether such Indebtedness or guarantee now exists or is created after the issuance of the Notes, if both: 

(i) such default either results from the failure to pay any principal of such Indebtedness at its stated final maturity (after
giving effect to any applicable grace periods) or relates to an obligation other than the obligation to pay principal of any such Indebtedness at its stated final maturity and results in the holder or holders of such Indebtedness causing such
Indebtedness to become due prior to its stated final maturity; and 
 (ii) the principal amount of such Indebtedness,
together with the principal amount of any other such Indebtedness in default for failure to pay principal at stated final maturity (after giving effect to any applicable grace periods), or the maturity of which has been so accelerated, aggregate
$50.0 million or more at any one time outstanding; 
 (e) failure by Milacron or any Significant Party (or group of
Restricted Subsidiaries that together (determined as of the most recent consolidated financial statements of Parent Guarantor for a fiscal quarter end) would constitute a Significant Party) to pay final non-appealable judgments aggregating in excess
of $50.0 million (net of any amounts covered by indemnities or enforceable insurance policies 

  
 -78- 








 
issued by solvent insurance carriers), which final judgments remain unpaid, undischarged and unstayed for a period of more than 90 days after such judgment becomes final, and in the event such
judgment is covered by insurance, and enforcement proceedings have been commenced by any creditor upon such judgment or decree which is not promptly stayed; 

(f) an Issuer or any Significant Party (or group of Restricted Subsidiaries that together (determined as of the most recent
consolidated financial statements of Parent Guarantor for a fiscal quarter end) would constitute a Significant Party), pursuant to or within the meaning of any Bankruptcy Law: 

(i) commences proceedings to be adjudicated bankrupt or insolvent;

receiver, liquidator, assignee, trustee, sequestrator or other similar official of it or for all or substantially all of its property; or 

(iv) makes a general assignment for the benefit of its creditors; 

(g) a court of competent jurisdiction enters an order or decree under any Bankruptcy Law that: 

(i) is for relief against an Issuer or any Significant Party (or group of Restricted Subsidiaries that together (determined as
of the most recent consolidated financial statements of Parent Guarantor for a fiscal quarter end) would constitute a Significant Party), in a proceeding in which an Issuer or any Significant Party, is to be adjudicated bankrupt or insolvent; 

(ii) appoints a receiver, liquidator, assignee, trustee, sequestrator or other similar official of an Issuer or any Significant

property of an Issuer or any Significant Party (or group of Restricted Subsidiaries that together (determined as of the most recent consolidated financial statements of Parent Guarantor for a fiscal quarter end) would constitute a Significant
Party); or 
 (iii) orders the liquidation of an Issuer or any Significant Party (or group of Restricted Subsidiaries that
together (determined as of the most recent consolidated financial statements of Parent Guarantor for a fiscal quarter end) would constitute a Significant Party); 

and the order or decree remains unstayed and in effect for 60 consecutive days; or 

(h) the Guarantee of any Significant Party shall for any reason cease to be in full force and effect or be declared null and
void or any responsible officer of any Guarantor that is a Significant Party (or the responsible officers of any group of Restricted Subsidiaries that together (determined as of the most recent consolidated financial statements of Parent Guarantor
for a fiscal quarter end) would constitute a Significant Party), as the case may be, denies that it has any further liability under its Guarantee or gives notice to such effect, in each case, other than by reason of the termination of this Indenture
or the release of any such Guarantee in accordance with this Indenture. 
 Section 6.02.
ACCELERATION 
 (a) If any Event of Default (other than an Event of Default
of the type specified in clause (f) or (g) of Section 6.01) occurs and is continuing under this Indenture, the Trustee by notice to the Issuers or the Holders of at least 25% in principal amount of the then total outstanding Notes by
notice to the Issuers and the 

  
 -79- 








 
Trustee, in either case specifying in such notice the respective Event of Default and that such notice is a “notice of acceleration,” may declare the principal, premium, if any,
interest and any other monetary obligations on all the then outstanding Notes to be due and payable immediately. Upon the effectiveness of such declaration, such principal and interest shall be due and payable immediately. Notwithstanding the
foregoing, in the case of an Event of Default arising under clause (f) or (g) of Section 6.01, all outstanding Notes shall become due and payable immediately without further action or notice. The Trustee may withhold from the Holders
notice of any continuing Default or Event of Default, except a Default or Event of Default relating to the payment of principal, premium, if any, or interest, if it determines that withholding notice is in their interest. 

(b) The Holders of a majority in aggregate principal amount of the then outstanding Notes by notice to the Trustee may on behalf of the
Holders of all of the Notes waive any existing Default and its consequences under this Indenture (except a continuing Default in the payment of interest on, premium, if any, or the principal of any Note held by a non-consenting Holder) and rescind
any acceleration and its consequences with respect to the Notes, provided such rescission does not conflict with any judgment of a court of competent jurisdiction. In the event of any Event of Default specified in clause (d) of
Section 6.01 hereof, such Event of Default and all consequences thereof (excluding any resulting payment default, other than as a result of acceleration of the Notes) shall be annulled, waived and rescinded, automatically and without any action
by the Trustee or the Holders, if within 20 days after such Event of Default arose: 
 (i) the Indebtedness or guarantee that
is the basis for such Event of Default has been discharged; 
 (ii) holders thereof have rescinded or waived the
acceleration, notice or action (as the case may be) giving rise to such Event of Default; or 
 (iii) the default that is the
basis for such Event of Default has been cured. 
 Section 6.03. OTHER
REMEDIES 
 If an Event of Default occurs and is continuing, the Trustee may pursue
any available remedy to collect the payment of principal, premium, if any, and interest on the Notes or to enforce the performance of any provision of the Notes or this Indenture. 

The Trustee may maintain a proceeding even if it does not possess any of the Notes or does not produce any of them in the proceeding. A delay
or omission by the Trustee or any Holder in exercising any right or remedy accruing upon an Event of Default shall not impair the right or remedy or constitute a waiver of or acquiescence in the Event of Default. All remedies shall be cumulative to
the extent permitted by law. 
 Section 6.04. WAIVER OF
DEFAULTS 
 Subject to Section 6.02 hereof, Holders of not less than a majority
in aggregate principal amount of the then outstanding Notes by notice to the Trustee may on behalf of the Holders of all of the Notes waive any existing Default and its consequences hereunder (except a continuing Default in the payment of the
principal of, premium, if any, or interest on, any Note held by a non-consenting Holder). Upon any such waiver, such Default shall cease to exist, and any Event of Default arising therefrom shall be deemed to have been cured for every purpose of
this Indenture; but no such waiver shall extend to any subsequent or other Default or impair any right consequent thereon. 

Section 6.05. CONTROL BY MAJORITY

 Subject to Section 7.01(e), Holders of a majority in principal amount of the then total outstanding Notes may direct the time, method
and place of conducting any proceeding for any remedy available to the Trustee or of exercising any trust or power conferred on the Trustee. The Trustee, however, may refuse to follow any direction that conflicts with law or this Indenture or that
the Trustee determines is unduly prejudicial to the rights of any other Holder of a Note or that would involve the Trustee in personal liability. 

  
 -80- 








 Section 6.06. LIMITATION ON
SUITS 
 Subject to Section 6.07 hereof, no Holder of a Note may pursue
any remedy with respect to this Indenture or the Notes unless: 
 (a) such Holder has previously given the Trustee written
notice that an Event of Default is continuing; 
 (b) Holders of at least 25% in principal amount of the total outstanding
Notes have requested in writing the Trustee to pursue the remedy; 
 (c) Holders of the Notes have offered the Trustee
reasonable security or indemnity against any loss, liability or expense; 
 (d) the Trustee has not complied with such
request within 60 days after the receipt thereof and the offer of security or indemnity; and 
 (e) Holders of a majority in
principal amount of the total outstanding Notes have not given the Trustee a written direction inconsistent with such request within such 60-day period. 

A Holder of a Note may not use this Indenture to prejudice the rights of another Holder of a Note or to obtain a preference or priority over
another Holder of a Note. 
 Section 6.07. RIGHTS OF HOLDERS
TO RECEIVE PAYMENT 
 Notwithstanding any other
provision of this Indenture, the right of any Holder of a Note to receive payment of principal of, premium, if any, and interest on the Note, on or after the respective due dates expressed in the Note (including in connection with an Asset Sale
Offer or a Change of Control Offer), or to bring suit for the enforcement of any such payment on or after such respective dates, shall not be impaired or affected without the consent of such Holder. 

Section 6.08. COLLECTION SUIT BY
TRUSTEE 
 If an Event of Default specified in Section 6.01(a) or
(b) hereof occurs and is continuing, the Trustee is authorized to recover judgment in its own name and as trustee of an express trust against the Issuers for the whole amount of principal of, premium, if any, and interest remaining unpaid on
the Notes and interest on overdue principal and, to the extent lawful, interest and such further amount as shall be sufficient to cover the costs and expenses of collection, including the reasonable compensation, expenses, disbursements and advances
of the Trustee, its agents and counsel. 
 Section 6.09. RESTORATION OF
RIGHTS AND REMEDIES 
 If the Trustee or any
Holder has instituted any proceeding to enforce any right or remedy under this Indenture and such proceeding has been discontinued or abandoned for any reason, or has been determined adversely to the Trustee or to such Holder, then and in every such
case, subject to any determination in such proceedings, the Issuers, the Trustee and the Holders shall be restored severally and respectively to their former positions hereunder and thereafter all rights and remedies of the Trustee and the Holders
shall continue as though no such proceeding has been instituted. 
 Section 6.10. RIGHTS
AND REMEDIES CUMULATIVE 
 Except as otherwise
provided with respect to the replacement or payment of mutilated, destroyed, lost or stolen Notes in Section 2.07 hereof, no right or remedy herein conferred upon or reserved to the Trustee or to the Holders is intended to be exclusive of any
other right or remedy, and every right and remedy shall, to the extent permitted by law, be cumulative and in addition to every other right and remedy given hereunder or now or hereafter existing at law or in equity or otherwise. The assertion or
employment of any right or remedy hereunder, or otherwise, shall not prevent the concurrent assertion or employment of any other appropriate right or remedy. 

  
 -81- 








 Section 6.11. DELAY OR OMISSION
NOT WAIVER 
 No delay or omission of the Trustee or of any
Holder of any Note to exercise any right or remedy accruing upon any Event of Default shall impair any such right or remedy or constitute a waiver of any such Event of Default or an acquiescence therein. Every right and remedy given by this Article
or by law to the Trustee or to the Holders may be exercised from time to time, and as often as may be deemed expedient, by the Trustee or by the Holders, as the case may be. 

Section 6.12. TRUSTEE MAY FILE PROOFS OF
CLAIM 
 The Trustee is authorized to file such proofs of claim and other
papers or documents as may be necessary or advisable in order to have the claims of the Trustee (including any claim for the reasonable compensation, expenses, disbursements and advances of the Trustee and its agents and counsel) and the Holders of
the Notes allowed in any judicial proceedings relative to the Issuers (or any other obligor upon the Notes including the Guarantors), its creditors or its property and to collect, receive and distribute any money or other property payable or
deliverable on any such claims and any custodian in any such judicial proceeding is hereby authorized by each Holder to make such payments to the Trustee, and in the event that the Trustee shall consent to the making of such payments directly to the
Holders, to pay to the Trustee any amount due to them for the reasonable compensation, expenses, disbursements and advances of the Trustee and its agents and counsel, and any other amounts due to the Trustee under Section 7.07 hereof. To the
extent that the payment of any such compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, and any other amounts due to the Trustee under Section 7.07 hereof out of the estate in any such proceeding, shall be
denied for any reason, payment of the same shall be secured by a Lien on, and shall be paid out of, any and all distributions, dividends, money, securities and other properties that the Holders may be entitled to receive in such proceeding whether
in liquidation or under any plan of reorganization or arrangement or otherwise. Nothing herein contained shall be deemed to authorize the Trustee to authorize or consent to or accept or adopt on behalf of any Holder any plan of reorganization,
arrangement, adjustment or composition affecting the Notes or the rights of any Holder, or to authorize the Trustee to vote in respect of the claim of any Holder in any such proceeding. 

Section 6.13. PRIORITIES 

Any money or property collected by the Trustee pursuant to this Article VI and any money or other property distributable in respect of any
Obligations of the Issuers or the Guarantors under this Indenture after an Event of Default shall be applied in the following order: 

(a) First, to the Trustee, such Agent, their agents and attorneys for amounts due under Section 7.07 hereof; 

(b) Second, to Holders for amounts due and unpaid on the Notes for principal, premium, if any, and interest, ratably,
without preference or priority of any kind, according to the amounts due and payable on the Notes for principal, premium, if any, and interest, respectively; and 

(c) Third, to the Issuer or to such party as a court of competent jurisdiction shall direct including a Guarantor, if
applicable. 
 The Trustee may fix a record date and payment date for any payment to Holders pursuant to this Section 6.13. 

  
 -82- 








 Section 6.14. UNDERTAKING FOR
COSTS 
 In any suit for the enforcement of any right or remedy under this
Indenture or in any suit against the Trustee for any action taken or omitted by it as a Trustee, a court in its discretion may require the filing by any party litigant in the suit of an undertaking to pay the costs of the suit, and the court in its
discretion may assess reasonable costs, including reasonable attorneys’ fees, against any party litigant in the suit, having due regard to the merits and good faith of the claims or defenses made by the party litigant. This Section 6.14
does not apply to a suit by the Trustee, a suit by a Holder pursuant to Section 6.07 hereof, or a suit by Holders of more than 10% in principal amount of the then outstanding Notes. 

ARTICLE VII 
 TRUSTEE

 Section 7.01. DUTIES OF
TRUSTEE 
 (a) If an Event of Default has occurred and is continuing, the
Trustee shall exercise such of the rights and powers vested in it by this Indenture, and use the same degree of care and skill in its exercise, as a prudent person would exercise or use under the circumstances in the conduct of such person’s
own affairs. 
 (b) Except during the continuance of an Event of Default: 

(i) the duties of the Trustee shall be determined solely by the express provisions of this Indenture and the Trustee need
perform only those duties that are specifically set forth in this Indenture and no others, and no implied covenants or obligations shall be read into this Indenture against the Trustee; and 

(ii) in the absence of bad faith on its part, the Trustee may conclusively rely, as to the truth of the statements and the
correctness of the opinions expressed therein, upon certificates or opinions furnished to the Trustee and conforming to the form required in this Indenture. However, in the case of any such certificates or opinions which by any provision hereof are
specifically required to be furnished to the Trustee, the Trustee shall examine the certificates and opinions to determine whether or not they conform to the form requirements of this Indenture (but need not confirm or investigate the accuracy of
mathematical calculations and other facts stated therein). Except with respect to Section 4.01, the Trustee shall have no duty to inquire as to the performance of the covenants contained in Article IV or Article V.

misconduct, except that:

 (ii) the Trustee shall not be liable for any error of judgment made in good faith by a Responsible Officer, unless it is
proved in a court of competent jurisdiction that the Trustee was negligent in ascertaining the pertinent facts; and

the Trustee shall not be liable with respect to any action it takes or omits to take in good faith in accordance with a direction received by it pursuant to Section 6.02, 6.04 or 6.05 hereof. 

(d) Whether or not therein expressly so provided, every provision of this Indenture that in any way relates to the Trustee is subject to
paragraphs (a), (b) and (c) of this Section 7.01.

rights or powers under this Indenture at the request or direction of any of the Holders of the Notes unless the Holders have offered to the Trustee indemnity or security satisfactory to it against any loss, liability or expense. 

(f) The Trustee shall not be liable for interest on any money received by it except as the Trustee may agree in writing with the Issuers.
Money held in trust by the Trustee need not be segregated from other funds except to the extent required by law. 

  
 -83- 








 Section 7.02. RIGHTS OF
TRUSTEE 
 (a) The Trustee may conclusively rely upon any document believed
by it to be genuine and to have been signed or presented by the proper Person. The Trustee need not investigate any fact or matter stated in the document, but the Trustee, in its discretion, may make such further inquiry or investigation into such
facts or matters as it may see fit, and, if the Trustee shall determine to make such further inquiry or investigation, it shall be entitled to examine the books, records and premises of Milacron and the Restricted Subsidiaries, personally or by
agent or attorney at the sole cost of the Issuers and shall incur no liability or additional liability of any kind by reason of such inquiry or investigation.

financial or otherwise, in the performance of any of its duties hereunder, or in the exercise of any of its rights or powers if an indemnity satisfactory to it against such risk or liability is not assured to it. 

(g) The permissive rights of the Trustee to do things enumerated in this Indenture shall not be construed as a duty unless so specified
herein. 
 (h) The Trustee shall not be liable for any consequential loss (including, without limitation, loss of business, goodwill,
opportunity or profit of any kind) of the Issuers, any Subsidiary or any other Person. 
 (i) The rights, privileges, protections,
immunities and benefits given to the Trustee, including its right to be indemnified and/or secured, are extended to, and shall be enforceable by U.S. Bank National Association, and each agent, custodian and other person employed to act hereunder.
Absent willful misconduct or negligence, each Paying Agent and Registrar shall not be liable for acting in good faith on instructions believed by it to be genuine and from the proper party. 

Section 7.03. INDIVIDUAL RIGHTS OF
TRUSTEE 
 The Trustee in its individual or any other capacity may become the
owner or pledgee of Notes and may otherwise deal with Milacron or any Affiliate of Milacron with the same rights it would have if it were not Trustee. However, in the event that the Trustee acquires any conflicting interest it must eliminate such
conflict within 90 days, apply to the SEC for permission to continue as trustee or resign. Any Agent may do the same with like rights and duties. The Trustee is also subject to Sections 7.10 and 7.11 hereof. 

  
 -84- 








 Section 7.04. TRUSTEE’S
DISCLAIMER 
 The Trustee shall not be responsible for and makes no
representation as to the validity or adequacy of this Indenture or the Notes, it shall not be accountable for the Issuers’ use of the proceeds from the Notes or any money paid to an Issuer or upon an Issuer’s direction under any provision
of this Indenture, it shall not be responsible for the use or application of any money received by any Paying Agent other than the Trustee, and it shall not be responsible for any statement or recital herein or any statement in the Notes or any
other document in connection with the sale of the Notes or pursuant to this Indenture other than its certificate of authentication. 

Section 7.05. NOTICE OF
DEFAULTS 
 If a Default occurs and is continuing and if it is known to the
Trustee, the Trustee shall mail (or otherwise deliver in accordance with applicable DTC procedures) to the Holders a notice of the Default within 90 days after it occurs. Except in the case of a Default relating to the payment of principal, premium,
if any, or interest on any Note, the Trustee may withhold from the Holders notice of any continuing Default if and so long as a committee of its Responsible Officers in good faith determines that withholding the notice is in the interests of the
Holders. The Trustee shall not be deemed to know of any Default unless a Responsible Officer of the Trustee has actual knowledge thereof or unless written notice of any event which is such a Default is received by the Trustee in accordance with
Section 13.02 hereof at the Corporate Trust Office of the Trustee and such notice references the Notes and this Indenture. 

Section 7.06. REPORTS BY TRUSTEE TO
HOLDERS 
 Within 60 days after each April 15, beginning with the
April 15 following the date of this Indenture, and for so long as Notes remain outstanding, the Trustee shall mail (or otherwise deliver in accordance with applicable DTC procedures) to the Holders a brief report dated as of such reporting date
that complies with Trust Indenture Act Section 313(a) (excluding Section 313(a)(6)) (but if no event described in Trust Indenture Act Section 313(a) has occurred within the twelve months preceding the reporting date, no report need be
transmitted). The Trustee also shall comply with Trust Indenture Act Section 313(b)(2). The Trustee shall also deliver all reports as required by Trust Indenture Act Section 313(c). 

A copy of each report at the time of its delivery to the Holders shall be mailed to the Issuers and each stock exchange on which the Notes are
listed in accordance with Trust Indenture Act Section 313(d). The Issuers shall promptly notify the Trustee in writing if the Notes are listed on any stock exchange. 

Section 7.07. COMPENSATION AND
INDEMNITY 
 The Issuers shall pay to the Trustee from time to time such
compensation for its acceptance of this Indenture and services hereunder as the parties shall agree in writing from time to time. The Trustee’s compensation shall not be limited by any law on compensation of a trustee of an express trust. The
Issuers shall reimburse the Trustee promptly upon request for all reasonable disbursements, advances and expenses incurred or made by it in addition to the compensation for its services. Such expenses shall include the reasonable compensation,
disbursements and expenses of the Trustee’s agents and counsel. 
 The Issuers and the Guarantors, jointly and severally, shall
indemnify the Trustee and its officers, directors, employees, agents and any predecessor trustee (in its capacity as trustee) and its officers, directors, employees and agents for, and hold the Trustee harmless against, any and all loss, damage,
claims, liability or expense (including reasonable attorneys’ fees) incurred by it in connection with the acceptance or administration of this trust and the performance of its duties hereunder (including the costs and expenses of enforcing this
Indenture against the Issuers or any of the Guarantors (including this Section 7.07) or defending itself against any claim whether asserted by any Holder, an Issuer or any Guarantor, or liability in connection with the acceptance, exercise or
performance of any of its powers or duties hereunder). The Trustee shall notify the Issuers promptly of any claim for which it may seek indemnity. Failure by the Trustee to so notify the Issuers shall not relieve the Issuers of their obligations
hereunder except to the extent the Issuers have been materially prejudiced thereby. The Issuers shall defend the claim and the Trustee may have separate counsel and the Issuers shall pay the fees and expenses of such counsel. The Issuers need not
pay for any settlement made without its consent, which consent shall not be unreasonably withheld. The Issuers and Guarantors need not reimburse any expense or indemnify against any loss, liability or expense incurred by the Trustee through the
Trustee’s own willful misconduct, negligence or bad faith. 

  
 -85- 








 The obligations of the Issuers under this Section 7.07 shall survive the satisfaction and
discharge of this Indenture or the earlier resignation or removal of the Trustee. 
 To secure the payment obligations of the Issuers and
the Guarantors in this Section 7.07, the Trustee shall have a Lien prior to the Notes on all money or property held or collected by the Trustee. Such Lien shall survive the satisfaction and discharge of this Indenture. 

When the Trustee incurs expenses or renders services after an Event of Default specified in Section 6.01(f) or (g) hereof occurs,
the expenses and the compensation for the services (including the fees and expenses of its agents and counsel) are intended to constitute expenses of administration under any Bankruptcy Law. 

The Trustee shall comply with the provisions of Trust Indenture Act Section 313(b)(2) to the extent applicable. 

Section 7.08. REPLACEMENT OF TRUSTEE

 A resignation or removal of the Trustee and appointment of a successor Trustee shall become effective only upon the successor
Trustee’s acceptance of appointment as provided in this Section 7.08. The Trustee may resign in writing at any time and be discharged from the trust hereby created by so notifying the Issuers. The Holders of a majority in principal amount
of the then outstanding Notes may remove the Trustee by so notifying the Trustee and the Issuers in writing. The Issuers may remove the Trustee if: 

(a) the Trustee fails to comply with Section 7.10 hereof or Section 310 of the Trust Indenture Act; 

(b) the Trustee is adjudged a bankrupt or an insolvent or an order for relief is entered with respect to the Trustee under any
Bankruptcy Law; 
 (c) a custodian or public officer takes charge of the Trustee or its property; or 

(d) the Trustee becomes incapable of acting. 

If the Trustee resigns or is removed or if a vacancy exists in the office of Trustee for any reason, the Issuers shall promptly appoint a
successor Trustee. Within one year after the successor Trustee takes office, the Holders of a majority in principal amount of the then outstanding Notes may appoint a successor Trustee to replace the successor Trustee appointed by the Issuers. 

If a successor Trustee does not take office within 60 days after the retiring Trustee resigns or is removed, the retiring Trustee (at the
Issuers’ expense), the Issuers or the Holders of at least 10% in principal amount of the then outstanding Notes may petition any court of competent jurisdiction for the appointment of a successor Trustee. 

If the Trustee, after written request by any Holder who has been a Holder for at least six months, fails to comply with Section 7.10
hereof, such Holder may petition any court of competent jurisdiction for the removal of the Trustee and the appointment of a successor Trustee. 

A successor Trustee shall deliver a written acceptance of its appointment to the retiring Trustee and to the Issuers. Thereupon, the
resignation or removal of the retiring Trustee shall become effective, and the successor Trustee shall have all the rights, powers and duties of the Trustee under this Indenture. The successor Trustee shall mail (or otherwise deliver in accordance
with applicable DTC procedures) a notice of its succession to the Holders. The retiring Trustee shall promptly transfer all property held by it as Trustee to the successor Trustee; provided all sums owing to the Trustee hereunder have been
paid and subject to the Lien provided for in Section 7.07 hereof. Notwithstanding replacement of the Trustee pursuant to this Section 7.08, the Issuers’ obligations under Section 7.07 hereof shall continue for the benefit of the
retiring Trustee.

 Section 7.09. SUCCESSOR TRUSTEE
BY MERGER, ETC. 
 If the Trustee consolidates, merges or converts into, or
transfers all or substantially all of its corporate trust business to, another corporation, the successor corporation without any further act shall be the successor Trustee. 

Section 7.10. ELIGIBILITY; DISQUALIFICATION 

There shall at all times be a Trustee hereunder that is a corporation organized and doing business under the laws of the United States of
America or of any state thereof that is authorized under such laws to exercise corporate trustee power, that is subject to supervision or examination by federal or state authorities and that has, together with its parent, a combined capital and
surplus of at least $50,000,000 as set forth in its most recent published annual report of condition. 
 This Indenture shall always have a
Trustee who satisfies the requirements of Trust Indenture Act Sections 310(a)(1), (2) and (5). The Trustee is subject to Trust Indenture Act Section 310(b). 

Section 7.11. PREFERENTIAL COLLECTION OF CLAIMS
AGAINST ISSUERS 
 The Trustee is subject to Trust Indenture Act
Section 311(a), excluding any creditor relationship listed in Trust Indenture Act Section 311(b). A Trustee who has resigned or been removed shall be subject to Trust Indenture Act Section 311(a) to the extent indicated therein. 

ARTICLE VIII 
 LEGAL
DEFEASANCE AND COVENANT DEFEASANCE 
 Section 8.01. OPTION TO
EFFECT LEGAL DEFEASANCE OR COVENANT DEFEASANCE 

The Issuers may, at their option and at any time, elect to have either Section 8.02 or 8.03 hereof applied to all outstanding Notes upon
compliance with the conditions set forth below in this Article VIII. 
 Section 8.02.
LEGAL DEFEASANCE AND DISCHARGE 
 Upon the
Issuers’ exercise under Section 8.01 hereof of the option applicable to this Section 8.02, the Issuers and the Guarantors shall, subject to the satisfaction of the conditions set forth in Section 8.04 hereof, be deemed to have
been discharged from their obligations with respect to all outstanding Notes and Guarantees on the date the conditions set forth below are satisfied (“Legal Defeasance”). For this purpose, Legal Defeasance means that the Issuers
shall be deemed to have paid and discharged the entire Indebtedness represented by the outstanding Notes, which shall thereafter be deemed to be “outstanding” only for the purposes of Section 8.05 hereof and the other Sections of this
Indenture referred to in (a) and (b) below, and to have satisfied all its other obligations under such Notes and this Indenture including that of the Guarantors (and the Trustee, on demand of and at the expense of the Issuers, shall
execute proper instruments acknowledging the same), except for the following provisions which shall survive until otherwise terminated or discharged hereunder: 

(a) the rights of Holders to receive payments in respect of the principal of, premium, if any, and interest on the Notes when
such payments are due solely out of the trust created pursuant to this Indenture referred to in Section 8.04 hereof; 

(b) the Issuers’ obligations with respect to Notes concerning issuing temporary Notes, registration of such Notes,
mutilated, destroyed, lost or stolen Notes and the maintenance of an office or agency for payment and money for security payments held in trust; 

(c) the rights, powers, trusts, duties and immunities of the Trustee, and the Issuers’ obligations in connection
therewith; and 

  
 -87- 








 (d) this Section 8.02. 

If the Issuers exercise under Section 8.01 the option applicable to this Section 8.02, subject to satisfaction of the conditions set forth in
Section 8.04 hereof, payment of the Notes may not be accelerated because of an Event of Default under subsections (c), (d), (e), (f) (solely with respect to a Significant Party), (g) (solely with respect to a Significant Party) and
(h) of Section 6.01. Subject to compliance with this Article VIII, the Issuers may exercise their option under this Section 8.02 notwithstanding the prior exercise of its option under Section 8.03 hereof. 

Section 8.03. COVENANT DEFEASANCE 

Upon the Issuers’ exercise under Section 8.01 hereof of the option applicable to this Section 8.03, the Issuers and the
Guarantors shall, subject to the satisfaction of the conditions set forth in Section 8.04 hereof, be released from their obligations under the covenants contained in Sections 3.09, 4.03, 4.04, 4.05, 4.07, 4.08, 4.09, 4.10, 4.11, 4.12, 4.13,
4.14, 4.15, 4.16 and 4.17 hereof and clauses (iv) and (v) of Section 5.01(a), Sections 5.01(d) hereof with respect to the outstanding Notes on and after the date the conditions set forth in Section 8.04 hereof are satisfied
(“Covenant Defeasance”), and the Notes shall thereafter be deemed not “outstanding” for the purposes of any direction, waiver, consent or declaration or act of Holders (and the consequences of any thereof) in connection
with such covenants, but shall continue to be deemed “outstanding” for all other purposes hereunder (it being understood that such Notes shall not be deemed outstanding for accounting purposes). For this purpose, Covenant Defeasance means
that, with respect to the outstanding Notes, the Issuers may omit to comply with and shall have no liability in respect of any term, condition or limitation set forth in any such covenant, whether directly or indirectly, by reason of any reference
elsewhere herein to any such covenant or by reason of any reference in any such covenant to any other provision herein or in any other document and such omission to comply shall not constitute a Default or an Event of Default under Section 6.01
hereof, but, except as specified above, the remainder of this Indenture and such Notes shall be unaffected thereby. In addition, upon the Issuers’ exercise under Section 8.01 hereof of the option applicable to this Section 8.03 hereof,
subject to the satisfaction of the conditions set forth in Section 8.04 hereof, Sections 6.01(c) (solely with respect to the covenants that are released upon a Covenant Defeasance), 6.01(d), 6.01(e), 6.01(f) (solely with respect to a
Significant Party), 6.01(g) (solely with respect to a Significant Party) and 6.01(h) hereof shall not constitute Events of Default.

 (a) the Issuers shall irrevocably deposit with the
Trustee, in trust, for the benefit of the Holders of the Notes, cash in U.S. dollars, Government Securities, or a combination thereof, in such amounts as will be sufficient, in the opinion of a nationally recognized investment bank, appraisal firm
or firm of independent public accountants, to pay the principal amount of, premium, if any, and interest due on the Notes on the stated maturity date or on the Redemption Date, as the case may be, of such principal amount, premium, if any, and
interest on such Notes and the Issuers must specify whether such Notes are being defeased to maturity or to a particular Redemption Date. 

(b) in the case of Legal Defeasance, the Issuers shall have delivered to the Trustee an Opinion of Counsel confirming that,
subject to customary assumptions and exclusions, 
 (i) the Issuers have received from, or there has been published by, the
United States Internal Revenue Service a ruling, or 
 (ii) since the issuance of the Notes, there has been a change in the
applicable U.S. federal income tax law, 

  
 -88- 








 
in either case to the effect that, and based thereon such Opinion of Counsel shall confirm that, subject to customary assumptions and exclusions, the Holders of the Notes will not recognize
income, gain or loss for U.S. federal income tax purposes, as applicable, as a result of such Legal Defeasance and will be subject to U.S. federal income tax on the same amounts, in the same manner and at the same times as would have been the case
if such Legal Defeasance had not occurred; 
 (c) in the case of Covenant Defeasance, the Issuers shall have delivered to the
Trustee an Opinion of Counsel confirming that, subject to customary assumptions and exclusions, the Holders of the Notes will not recognize income, gain or loss for U.S. federal income tax purposes as a result of such Covenant Defeasance and will be
subject to such U.S. federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such Covenant Defeasance had not occurred; 

(d) no Default with respect to any covenant being defeased (other than that resulting from borrowing funds to be applied to
make such deposit and any similar and simultaneous deposit relating to other Indebtedness and, in each case, the granting of Liens in connection therewith) shall have occurred and be continuing on the date of such deposit; 

(e) such Legal Defeasance or Covenant Defeasance shall not result in a breach or violation of, or constitute a default under
any material mortgage, indenture (other than this Indenture) or instrument under which there is issued or by which there is secured or evidenced any Indebtedness for money borrowed to which Milacron or any Guarantor is a party or by which Milacron
or any Guarantor is bound (other than that resulting from any borrowing of funds to be applied to make the deposit required to effect such Legal Defeasance or Covenant Defeasance and any similar and simultaneous deposit relating to other
Indebtedness, and the granting of Liens in connection therewith); 
 (f) the Issuers shall have delivered to the Trustee an
Officer’s Certificate stating that the deposit was not made by the Issuers with the intent of defeating, hindering, delaying or defrauding any creditors of the Issuers or any Guarantor or others; and 

(g) the Issuers shall have delivered to the Trustee an Officer’s Certificate and an Opinion of Counsel (which Opinion of
Counsel may be subject to customary assumptions and exclusions) each stating that all conditions precedent provided for or relating to the Legal Defeasance or the Covenant Defeasance, as the case may be, have been complied with. 

Section 8.05. DEPOSITED CASH AND U.S.
GOVERNMENT SECURITIES TO BE HELD IN TRUST; OTHER MISCELLANEOUS PROVISIONS

 Subject to Section 8.06 hereof, all money and Government Securities (including the proceeds thereof) deposited with the
Trustee (or other qualifying trustee, collectively for purposes of this Section 8.05, the “Trustee”) pursuant to Section 8.04 hereof in respect of the outstanding Notes shall be held in trust and applied by the Trustee, in
accordance with the provisions of such Notes and this Indenture, to the payment, either directly or through any Paying Agent (including Milacron or a Guarantor acting as Paying Agent) as the Trustee may determine, to the Holders of such Notes of all
sums due and to become due thereon in respect of principal, premium, if any, and interest, but such money need not be segregated from other funds except to the extent required by law. 

The Issuers shall pay and indemnify the Trustee against any tax, fee or other charge imposed on or assessed against the cash or Government
Securities deposited pursuant to Section 8.04 hereof or the principal and interest received in respect thereof other than any such tax, fee or other charge which by law is for the account of the Holders of the outstanding Notes. 

Anything in this Article VIII to the contrary notwithstanding, the Trustee shall deliver or pay to the Issuers from time to time upon the
request of the Issuers any money or Government Securities held by it as provided in Section 8.04 hereof which, in the opinion of a nationally recognized firm of independent public accountants expressed in a written certification thereof
delivered to the Trustee (which may be the opinion delivered under Section 8.04(a) hereof), are in excess of the amount thereof that would then be required to be deposited to effect an equivalent Legal Defeasance or Covenant Defeasance. 

  
 -89- 








 Section 8.06. REPAYMENT TO
ISSUERS 
 Subject to any applicable abandoned property law, any money deposited with the Trustee
or any Paying Agent, or then held by the Issuers, in trust for the payment of the principal of, premium, if any, or interest on any Note and remaining unclaimed for two years after such principal, and premium, if any, or interest has become due and
payable shall be paid to the Issuers on their request or (if then held by an Issuer) shall be discharged from such trust; and the Holder of such Note shall thereafter look only to the Issuers for payment thereof, and all liability of the Trustee or
such Paying Agent with respect to such trust money, and all liability of the Issuers as trustee thereof, shall thereupon cease. 

Section 8.07. REINSTATEMENT 

If the Trustee or Paying Agent is unable to apply any United States dollars or Government Securities in accordance with Section 8.02 or
8.03 hereof, as the case may be, by reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application, then the Issuers’ obligations under this Indenture and the Notes shall
be revived and reinstated as though no deposit had occurred pursuant to Section 8.02 or 8.03 hereof until such time as the Trustee or Paying Agent is permitted to apply all such money in accordance with Section 8.02 or 8.03 hereof, as the
case may be; provided that, if the Issuers make any payment of principal of, premium, if any, or interest on any Note following the reinstatement of its obligations, the Issuers shall be subrogated to the rights of the Holders of such Notes
to receive such payment from the money held by the Trustee or Paying Agent. 
 ARTICLE IX

Section 9.01. WITHOUT CONSENT OF HOLDERS
OF NOTES

(a) to cure any ambiguity, omission, mistake, defect or inconsistency; 

(b) to provide for uncertificated Notes of such series in addition to or in place of Definitive Notes; 

(c) to comply with Section 5.01 hereof; 

(d) to provide for the assumption of the Issuers’ or any Guarantor’s obligations to the Holders; 

(e) to make any change that would provide any additional rights or benefits to the Holders or that does not adversely affect
the legal rights under this Indenture of any such Holder; 
 (f) to add covenants for the benefit of the Holders or to
surrender any right or power conferred upon the Issuers or any Guarantor; 
 (g) to comply with requirements of the SEC in

 -90- 








 (h) to evidence and provide for the acceptance and appointment under this
Indenture of a successor Trustee hereunder pursuant to the requirements hereof or to provide for the accession of the Trustee to any instrument in connection with the Notes; 

(i) to add a Guarantor under this Indenture and to allow any Guarantor to execute a supplemental indenture and/or a Guarantee
with respect to the Notes; 
 (j) to release a Guarantor upon its sale or designation as an Unrestricted Subsidiary or other
permitted release from its Guarantee; 
 (k) to provide for the issuance of Additional Notes in accordance with the
limitations set forth herein; 
 (l) to conform the text of this Indenture, Guarantees or the Notes to any provision of the
“Description of the Notes” in the Offering Memorandum to the extent that such provision was intended to be a verbatim recitation of a provision of this Indenture, Guarantee or the Notes, as certified by the Issuers in an Officer’s
Certificate; 
 (m) to make any changes with respect to the rights or obligations of the Trustee or other provisions relating
to the Trustee that do not adversely affect the rights of any Holder in any material respect; or 
 (n) to make any amendment
to the provisions of this Indenture relating to the transfer and legending of Notes as permitted by this Indenture, including, without limitation to facilitate the issuance and administration of the Notes; provided, however, that
(i) compliance with this Indenture as so amended would not result in Notes being transferred in violation of the Securities Act or any applicable securities law and (ii) such amendment does not materially and adversely affect the rights of
Holders to transfer Notes. 
 Upon the request of the Issuers accompanied by a resolution of their respective Board of Directors authorizing
the execution of any such amended or supplemental indenture, and upon receipt by the Trustee of the documents described in Section 7.02 hereof, the Trustee shall join with the Issuers and the Guarantors in the execution of any amended or
supplemental indenture authorized or permitted by the terms of this Indenture and to make any further appropriate agreements and stipulations that may be therein contained, but the Trustee shall have the right, but not the obligation to, enter into
such amended or supplemental indenture that affects their own rights, duties or immunities under this Indenture or otherwise. Notwithstanding the foregoing, an Opinion of Counsel shall not be required in connection with the addition of a Guarantor
under this Indenture upon execution and delivery by such Guarantor and the Trustee of a supplemental indenture to this Indenture, the form of which is attached as Exhibit D hereto. 

Section 9.02. WITH CONSENT OF HOLDERS OF
NOTES 
 Except as provided below in this Section 9.02, the Issuers, the
Guarantors and the Trustee may amend or supplement this Indenture, the Notes and the Guarantees with the consent of the Holders of at least a majority in principal amount of the Notes (including Additional Notes, if any) then outstanding voting as a
single class (including consents obtained in connection with a tender offer or exchange offer for, or purchase of, the Notes), and, subject to Sections 6.04 and 6.07 hereof, any existing Default or Event of Default (other than a Default or Event of
Default in the payment of the principal of, premium, if any, or interest on the Notes, except a payment default resulting from an acceleration that has been rescinded) or compliance with any provision of this Indenture, the Guarantees or the Notes
may be waived with the consent of the Holders of a majority in principal amount of the then outstanding Notes (including Additional Notes, if any), voting as a single class (including consents obtained in connection with a tender offer or exchange
offer for, or purchase of, the Notes). Section 2.08 hereof, Section 2.09 hereof and Section 2.14 hereof shall determine which Notes are considered to be “outstanding” for the purposes of this Section 9.02. 

  
 -91- 








 Upon the request of the Issuers accompanied by a resolution of their respective Board of
Directors authorizing the execution of any such amended or supplemental indenture, and upon the filing with the Trustee of evidence of the consent of the Holders as aforesaid, and upon receipt by the Trustee of the documents described in
Section 7.02 hereof, the Trustee shall join with the Issuers in the execution of such amended or supplemental indenture unless such amended or supplemental indenture directly affects their own rights, duties or immunities under this Indenture
or otherwise, in which case the Trustee may in its discretion, but shall not be obligated to, enter into such amended or supplemental indenture. 

It shall not be necessary for the consent of the Holders under this Section 9.02 to approve the particular form of any proposed amendment
or waiver, but it shall be sufficient if such consent approves the substance thereof. 
 After an amendment, supplement or waiver under this
Section 9.02 becomes effective, the Issuers shall mail (or otherwise deliver in accordance with applicable DTC procedures) to the Holders affected thereby a notice briefly describing the amendment, supplement or waiver. Any failure of the
Issuers to mail such notice, or any defect therein, shall not, however, in any way impair or affect the validity of any such amended or supplemental indenture or waiver. 

Without the consent of each affected Holder, an amendment or waiver under this Section 9.02 may not, with respect to any Notes held by a
non-consenting Holder: 
 (a) reduce the principal amount of such Notes whose Holders must consent to an amendment,
supplement or waiver; 
 (b) reduce the principal amount of or change the fixed maturity of any such Note or alter or waive
the provisions with respect to the redemption of such Notes (other than provisions relating to Section 3.09, Section 4.10 and Section 4.14 hereof and other than the notice provisions); 

(c) reduce the rate of or change the time for payment of interest on any Note; 

(d) waive a Default or Event of Default in the payment of principal of or premium, if any, or interest on the Notes (except a
rescission of acceleration of the Notes by the Holders of at least a majority in aggregate principal amount of the Notes and a waiver of the payment default that resulted from such acceleration) or in respect of a covenant or provision contained in
this Indenture or any Guarantee which cannot be amended or modified without the consent of all Holders; 
 (e) make any Note
payable in money other than that stated therein; 
 (f) make any change in the provisions of this Indenture relating to
waivers of past Defaults or the rights of Holders to receive payments of principal of or premium, if any, or interest on the Notes; 

(g) make any change in these amendment and waiver provisions; 

(h) impair the right of any Holder to receive payment of principal of, or interest on such Holder’s Notes on or after the
due dates therefor or to institute suit for the enforcement of any payment on or with respect to such Holder’s Notes; 

(i) make any change to the ranking of the Notes (or related Guarantees) that would adversely affect the Holders; or 

(j) except as expressly permitted by this Indenture, modify the Guarantees of any Significant Party in any manner adverse to
the Holders. 

  
 -92- 








 Section 9.03. COMPLIANCE WITH
TRUST INDENTURE ACT 
 Every amendment
or supplement to this Indenture or the Notes shall be set forth in an amended or supplemental indenture that complies in all material respects with the Trust Indenture Act as then in effect. 

Section 9.04. REVOCATION AND EFFECT OF
CONSENTS 
 Until an amendment, supplement or waiver becomes
effective, a consent to it by a Holder is a continuing consent by the Holder and every subsequent Holder of a Note or portion of a Note that evidences the same debt as the consenting Holder’s Note, even if notation of the consent is not made on
any Note. However, any such Holder or subsequent Holder may revoke the consent as to its Note if the Trustee receives written notice of revocation before the date the waiver, supplement or amendment becomes effective. An amendment, supplement or
waiver becomes effective in accordance with its terms and thereafter binds every Holder. 
 The Issuers may, but shall not be obligated to,
fix a record date for the purpose of determining the Holders entitled to consent to any amendment, supplement, or waiver. If a record date is fixed, then, notwithstanding the preceding paragraph, those Persons who were Holders at such record date
(or their duly designated proxies), and only such Persons, shall be entitled to consent to such amendment, supplement, or waiver or to revoke any consent previously given, whether or not such Persons continue to be Holders after such record date. No
such consent shall be valid or effective for more than 90 days after such record date unless the consent of the requisite number of Holders has been obtained. 

Section 9.05. NOTATION ON OR EXCHANGE
OF NOTES 
 The Trustee may place an appropriate
notation about an amendment, supplement or waiver on any Note thereafter authenticated. The Issuers in exchange for all Notes may issue and the Trustee shall, upon receipt of an Authentication Order, authenticate new Notes that reflect the
amendment, supplement or waiver. 
 Failure to make the appropriate notation or issue a new Note shall not affect the validity and effect of
such amendment, supplement or waiver. 
 Section 9.06. TRUSTEE TO
SIGN AMENDMENTS, ETC. 
 The Trustee shall sign any amendment,
supplement or waiver authorized pursuant to this Article IX if the amendment or supplement does not adversely affect the rights, duties, liabilities or immunities of the Trustee. None of the Issuers nor any Guarantor may sign an amendment,
supplement or waiver until the relevant Board of Directors (or similar governing body) approves it. In executing any amendment, supplement or waiver, the Trustee shall be entitled to receive, and (subject to Section 7.01 hereof) shall be fully
protected in relying upon, in addition to the documents required by Section 13.04 hereof, an Officer’s Certificate and an Opinion of Counsel stating that the execution of such amended or supplemental indenture is authorized or permitted by
this Indenture and that such amendment, supplement or waiver is the legal, valid and binding obligation of the Issuers and any Guarantors party thereto, enforceable against them in accordance with its terms, subject to customary exceptions, and
complies with the provisions hereof (including Section 9.03). Notwithstanding the foregoing, an Opinion of Counsel shall not be required in connection with the addition of a Guarantor under this Indenture upon execution and delivery by such
Guarantor and the Trustee of a supplemental indenture to this Indenture, the form of which is attached as Exhibit D hereto. 

Section 9.07. PAYMENT FOR
CONSENT 
 Neither an Issuer nor any Affiliate of an Issuer shall,
directly or indirectly, pay or cause to be paid any consideration, whether by way of interest, fee or otherwise, to any Holder for or as an inducement to any consent, waiver or amendment of any of the terms or provisions of this Indenture or the
Notes unless such consideration is offered to all Holders and is paid to all Holders that so consent, waive or agree to amend in the time frame set forth in solicitation documents relating to such consent, waiver or agreement. 

  
 -93- 








 ARTICLE X 

GUARANTEES 

Section 10.01. GUARANTEE 

Subject to this Article X, each of the Guarantors hereby, jointly, severally and unconditionally guarantees to each Holder of a Note
authenticated and delivered by the Trustee and to the Trustee and its successors and assigns, that: (a) the principal of and interest and premium, if any, on the Notes shall be promptly paid in full when due, whether at maturity, by
acceleration, redemption or otherwise, and interest on the overdue principal of and interest on the Notes, if any, if lawful, and all other obligations of the Issuers to the Holders or the Trustee hereunder or thereunder shall be promptly paid in
full or performed, all in accordance with the terms hereof and thereof; and (b) in case of any extension of time of payment or renewal of any Notes or any of such other obligations, that same shall be promptly paid in full when due or performed
in accordance with the terms of the extension or renewal, whether at stated maturity, by acceleration or otherwise. Failing payment when due of any amount so guaranteed or any performance so guaranteed for whatever reason, the Guarantors shall be
jointly and severally obligated to pay the same immediately. Each Guarantor agrees that this is a guarantee of payment and not a guarantee of collection. 

The Guarantors hereby agree that their obligations hereunder shall be unconditional, irrespective of the validity, regularity or
enforceability of this Indenture, the Notes or the obligations of the Issuers hereunder or thereunder, the absence of any action to enforce the same, any waiver or consent by any Holder with respect to any provisions hereof or thereof, the recovery
of any judgment against the Issuers or any Guarantor, any action to enforce the same or any other circumstance which might otherwise constitute a legal or equitable discharge or defense of a Guarantor. Each Guarantor hereby waives diligence,
presentment, demand of payment, filing of claims with a court in the event of insolvency or bankruptcy of the Issuers, any right to require a proceeding first against the Issuers, protest, notice and all demands whatsoever and covenants that this
Guarantee shall not be discharged except by complete performance of the obligations contained in the Notes and this Indenture. 
 Each
Guarantor also agrees to pay any and all costs and expenses (including reasonable attorneys’ fees) incurred by the Trustee or any Holder in enforcing any rights under this Section 10.01. 

If any Holder or the Trustee is required by any court or otherwise to return to the Issuers, the Guarantors or any custodian, trustee,
liquidator or other similar official acting in relation to either the Issuers or the Guarantors, any amount paid either to the Trustee or such Holder, this Guarantee, to the extent theretofore discharged, shall be reinstated in full force and
effect. 
 Each Guarantor agrees that it shall not be entitled to any right of subrogation in relation to the Holders in respect of any
obligations guaranteed hereby until payment in full of all obligations guaranteed hereby. Each Guarantor further agrees that, as between the Guarantors, on the one hand, and the Holders and the Trustee, on the other hand, (x) the maturity of
the obligations guaranteed hereby may be accelerated as provided in Article VI hereof for the purposes of this Guarantee, notwithstanding any stay, injunction or other prohibition preventing such acceleration in respect of the obligations guaranteed
hereby, and (y) in the event of any declaration of acceleration of such obligations as provided in Article VI hereof, such obligations (whether or not due and payable) shall forthwith become due and payable by the Guarantors for the purpose of
this Guarantee. The Guarantors shall have the right to seek contribution from any non-paying Guarantor so long as the exercise of such right does not impair the rights of the Holders under the Guarantees. 

Unless and until released in accordance with Section 10.06, each Guarantee shall remain in full force and effect and continue to be
effective should any petition be filed by or against the Issuers for liquidation, reorganization, should the Issuers become insolvent or make an assignment for the benefit of creditors or should a receiver or trustee be appointed for all or any
significant part of the Issuers’ assets, and shall, to the fullest extent permitted by law, continue to be effective or be reinstated, as the case may be, if at any time payment and performance of the Notes are, pursuant to applicable law,
rescinded or reduced in amount, or must otherwise be restored or returned by any obligee on the Notes or Guarantees, whether as a “voidable preference,” “fraudulent transfer” or otherwise, all as though such payment or
performance had not been made. In the event that any 

  
 -94- 








 
payment or any part thereof, is rescinded, reduced, restored or returned, the Notes shall, to the fullest extent permitted by law, be reinstated and deemed reduced only by such amount paid and
not so rescinded, reduced, restored or returned. 
 In case any provision of any Guarantee shall be invalid, illegal or unenforceable, the
validity, legality, and enforceability of the remaining provisions shall not in any way be affected or impaired thereby. 
 The Guarantee
issued by any Guarantor shall be a general senior obligation of such Guarantor and shall be pari passu in right of payment with all existing and future Senior Indebtedness of such Guarantor, if any. 

Each payment to be made by a Guarantor in respect of its Guarantee shall be made without set-off, counterclaim, reduction or diminution of any
kind or nature. 
 Section 10.02. LIMITATION ON GUARANTOR
LIABILITY 
 Each Guarantor, and by its acceptance of Notes, each
Holder, hereby confirms that it is the intention of all such parties that the Guarantee of such Guarantor not constitute a fraudulent transfer or conveyance for purposes of Bankruptcy Law, the Uniform Fraudulent Conveyance Act, the Uniform
Fraudulent Transfer Act or any similar federal or state law to the extent applicable to any Guarantee. To effectuate the foregoing intention, the Trustee, the Holders and the Guarantors hereby irrevocably agree that the obligations of each Guarantor
shall be limited to the maximum amount as will, after giving effect to such maximum amount and all other contingent and fixed liabilities of such Guarantor that are relevant under such laws and after giving effect to any collections from, rights to
receive contribution from or payments made by or on behalf of any other Guarantor in respect of the obligations of such other Guarantor under this Article X, result in the obligations of such Guarantor (other than a company that is a direct or
indirect parent of Milacron) under its Guarantee not constituting a fraudulent conveyance or fraudulent transfer under applicable law. Each Guarantor that makes a payment under its Guarantee shall be entitled upon payment in full of all guaranteed
obligations under this Indenture to contribution or reimbursement from each other Guarantor in an amount equal to such other Guarantor’s pro rata portion of such payment based on the respective net assets of all the Guarantors at the time of
such payment determined in accordance with GAAP. 
 Section 10.03. EXECUTION AND
DELIVERY OF GUARANTEE 
 To evidence its
Guarantee set forth in Section 10.01 hereof, each Guarantor hereby agrees that this Indenture or a supplemental indenture hereto in substantially the form of Exhibit D hereto, as the case may be, shall be executed on behalf of such Guarantor by
its President, Chairman, Chief Executive Officer, one of its Vice Presidents, one of its Assistant Vice Presidents, its Chief Financial Officer or Treasurer (or by the President, Chairman, Chief Executive Officer, one of the Vice Presidents, one of
the Assistant Vice Presidents, the Chief Financial Officer or the Treasurer of its sole member, as applicable). 
 Each Guarantor hereby
agrees that its Guarantee set forth in Section 10.01 hereof shall remain in full force and effect notwithstanding the absence of the endorsement of any notation of such Guarantee on the Notes. 

If an Officer whose signature is on this Indenture no longer holds that office at the time the 

Trustee authenticates the Note, the Guarantee shall be valid nevertheless. 

The delivery of any Note by the Trustee, after the authentication thereof hereunder, shall constitute due delivery of the Guarantee set forth
in this Indenture on behalf of the Guarantors. 
 If required by Section 4.15 hereof, the Issuers shall cause any newly created or
acquired Restricted Subsidiary to comply with the provisions of Section 4.15 hereof and this Article X, to the extent applicable.

 Section 10.04.
SUBROGATION 
 Each Guarantor shall be subrogated to all rights of
Holders against the Issuers in respect of any amounts paid by any Guarantor pursuant to the provisions of Section 10.01 hereof; provided that, if an Event of Default has occurred and is continuing, no Guarantor shall be entitled to
enforce or receive any payments arising out of, or based upon, such right of subrogation until all amounts then due and payable by the Issuers under this Indenture or the Notes shall have been paid in full. 

Section 10.05. BENEFITS ACKNOWLEDGED 

Each Guarantor acknowledges that it will receive direct and indirect benefits from the financing arrangements contemplated by this Indenture
and that the guarantee and waivers made by it pursuant to its Guarantee are knowingly made in contemplation of such benefits. 

Section 10.06. RELEASE OF
GUARANTEES 
 A Guarantee by a Guarantor shall be automatically and unconditionally
released, discharged and terminated and no further action by the Guarantor, the Issuers or the Trustee is required for the release of the Guarantor’s Guarantee, upon: 

(a) any sale, exchange or transfer (by merger or otherwise) of (i) the Capital Stock of such Guarantor (including any
sale, exchange or transfer), after which the applicable Guarantor is no longer a Restricted Subsidiary or (ii) all or substantially all the assets of such Guarantor, which sale, exchange or transfer is made in compliance with the applicable
provisions of this Indenture; provided, however, that such Guarantor is also released from its guarantees and all pledges and security, if any, granted in connection with the ABL Credit Agreement, the Term Loan Credit Agreement and the Secured
Notes; 
 (b) in the case of a guarantee as a result of compliance with Section 4.12, the release, discharge or
termination of the guarantee by such Guarantor of the guarantee that resulted in the creation of such Guarantee (it being understood that a release subject to contingent reinstatement is still a release and that if such guarantee is reinstated, such
Guarantee shall also be reinstated to the extent that such Guarantor would then be required to provide a Guarantee), except a release, discharge or termination by or as a result of payment under such guarantee; 

(c) the designation of any Restricted Subsidiary that is a Guarantor as an Unrestricted Subsidiary in accordance with this
Indenture; 
 (d) upon the merger or consolidation of any Guarantor with and into Milacron or another Guarantor that is the
surviving Person in such merger or consolidation, or upon the liquidation of such Guarantor following the transfer of all of its assets to Milacron or another Guarantor; 

(e) the exercise by the Issuers of its Legal Defeasance option or Covenant Defeasance option in accordance with Article VIII
hereof or the discharge of the Issuers’ obligations under this Indenture in accordance with Article XII hereof; 
 (f)
subject to customary contingent reinstatement provisions, upon payment in full of the aggregate principal amount of all Notes then outstanding and all other applicable Obligations Guaranteed by such Guarantor then due and owing; or 

(g) (i) the release, discharge or termination of the guarantee by such Guarantor (or, in the case of the ABL Credit Agreement,
such Guarantor ceasing to be a borrower thereunder) under each of the ABL Credit Agreement, the Term Loan Credit Agreement and the Secured Notes or (ii) in the case of a guarantee made by a Guarantor as a result of its incurrence or guarantee
of other Indebtedness pursuant to Section 4.15 hereof, the release, discharge or termination of relevant Indebtedness or guarantee thereunder, as applicable (it being understood that a release subject to contingent reinstatement is still a
release and that if such guarantee is reinstated, such Guarantee shall also be reinstated to the extent that such Guarantor would then be required to provide a Guarantee), in each case, except a release, discharge or termination by or as a result of
payment under such Guarantee.

SATISFACTION AND DISCHARGE 

Section 12.01. SATISFACTION AND
DISCHARGE 
 This Indenture shall be discharged and shall cease to be of further
effect as to all Notes, when either: 
 (a) all Notes theretofore authenticated and delivered, except lost, stolen or
destroyed Notes which have been replaced or paid and Notes for whose payment money has theretofore been deposited in trust, have been delivered to the Trustee for cancellation; or 

(b) (i) all Notes not theretofore delivered to the Trustee for cancellation have become due and payable by reason of the making
of a notice of redemption or otherwise, will become due and payable within one year or are to be called for redemption and redeemed within one year under arrangements satisfactory to the Trustee for the giving of notice of redemption by the Trustee
in the name, and at the expense, of the Issuers, and the Issuers or any Guarantor has irrevocably deposited or caused to be deposited with the Trustee as trust funds in trust solely for the benefit of the Holders of the Notes, cash in U.S. dollars,
Government Securities, or a combination thereof, in such amounts as will be sufficient, without consideration of any reinvestment of interest to pay and discharge the entire indebtedness on the Notes not theretofore delivered to the Trustee for
cancellation for principal, premium, if any, and accrued interest to the date of maturity or redemption; 
 (ii) the Issuers
have paid or caused to be paid all sums payable by them under this Indenture; and 
 (iii) the Issuers have delivered
irrevocable instructions to the Trustee to apply the deposited money toward the payment of the Notes at maturity or the Redemption Date, as the case may be. 

In addition, the Issuers must deliver an Officer’s Certificate and an Opinion of Counsel to the Trustee stating that all conditions
precedent to satisfaction and discharge have been satisfied; provided, however, that any counsel may rely on an Officer’s Certificate as to matters of fact. 

Notwithstanding the satisfaction and discharge of this Indenture, if money shall have been deposited with the Trustee pursuant to subsection
(b)(i) of this Section 12.01, the provisions of Section 12.02 and Section 8.06 hereof shall survive. 

Section 12.02. APPLICATION OF TRUST
MONEY 
 Subject to the provisions of Section 8.06 hereof, all money deposited
with the Trustee pursuant to Section 12.01 hereof shall be held in trust and applied by it, in accordance with the provisions of the Notes and this Indenture, to the payment, either directly or through any Paying Agent (including an Issuer
acting as its own Paying Agent) as the Trustee may determine, to the Persons entitled thereto, of the principal (and premium, if any) and interest for whose payment such money has been deposited with the Trustee; but such money need not be
segregated from other funds except to the extent required by law. 
 If the Trustee or Paying Agent is unable to apply any money or
Government Securities in accordance with Section 12.01 hereof by reason of any legal proceeding or by reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application, the
Issuers’ and any Guarantor’s obligations under this Indenture and the Notes shall be revived and reinstated as though no deposit 

  
 -97- 








 
had occurred pursuant to Section 12.01 hereof; provided that if the Issuers have made any payment of principal of, premium, if any, or interest on any Notes because of the
reinstatement of its obligations, the Issuers shall be subrogated to the rights of the Holders of such Notes to receive such payment from the money or Government Securities held by the Trustee or Paying Agent.

 [Back of Note] 

7.750% Senior Note due 2021 

Capitalized terms used herein shall have the meanings assigned to them in the Indenture referred to below unless otherwise indicated. 

1. INTEREST. 
 Milacron LLC, a
Delaware limited liability company (“Milacron”) and Mcron Finance Corp., a Delaware corporation (“Finance Corp” and together with Milacron, the “Issuers”), promise to pay interest on the principal
amount of this Note at a rate per annum set forth below from March 28, 2013 until maturity. The Issuers will pay interest on this Note semi-annually in arrears on February 15 and August 15 of each year, commencing on August 15,
2013, or if any such day is not a Business Day, on the next succeeding Business Day (each, an “Interest Payment Date”), and no interest shall accrue on such payment for the intervening period. The Issuers will make each interest
payment to the Holder of record of this Note on the immediately preceding February 1 and August 1, commencing on August 1, 2013 (each, a “Record Date”). Interest on this Note will accrue from the most recent date to
which interest has been paid or, if no interest has been paid, from and including March 28, 2013. The Issuers will pay interest (including post-petition interest in any proceeding under any Bankruptcy Law) on overdue principal and premium, if
any, from time to time on demand at the rate then in effect; they shall pay interest (including post-petition interest in any proceeding under any Bankruptcy Law) on overdue installments of interest (without regard to any applicable grace periods),
from time to time on demand at the same rate to the extent lawful. Interest will be computed on the basis of a 360-day year comprised of twelve 30-day months. Interest will be fixed at a rate equal to 7.750%. 

2. METHOD OF PAYMENT. 
 The
Issuers will pay interest on this Note to the Person who is the registered Holder of this Note at the close of business on the Record Date (whether or not a Business Day) next preceding the Interest Payment Date, even if this Note is canceled after
such record date and on or before such Interest Payment Date, except as provided in Section 2.12 of the Indenture with respect to defaulted interest. Payment of interest may be made by check mailed to the Holders at their addresses set forth in
the Note Register of Holders, provided that [all payments of principal, premium, if any, and interest on, this Note will be made by wire transfer of immediately available funds to the accounts specified by the Holder or Holders thereof to the
Issuers or the Paying Agent at least five Business Days in advance of the applicable Interest Payment Date]1 [all payments of principal, premium, if any, and interest on, this Note will be made by
wire transfer to a U.S. dollar account maintained by the payee with a bank in the United States if such Holder elects payment by wire transfer by giving written notice to the Trustee or the Paying Agent to such effect designating such account no
later than 30 days immediately preceding the relevant due date for payment (or such other date as the Trustee may accept in its discretion)].2 Such payment shall be in such coin or currency of the
United States of America as at the time of payment is legal tender for payment of public and private debts. 
 3. PAYING AGENT AND
REGISTRAR. 
 Initially, U.S. Bank National Association, the Trustee under the Indenture, will act as Paying Agent and Registrar. The Issuers
may change any Paying Agent or Registrar without notice to the Holders. Milacron or any of its Subsidiaries may act as Paying Agent or Registrar.

 4. INDENTURE. 

The Issuers issued the Notes under an Indenture, dated as of March 28, 2013 (the “Indenture”), among the Issuers, the
Guarantors from time to time parties thereto, and the Trustee. This Note is one of a duly authorized issue of notes of the Issuers designated as their Senior Notes due February 15, 2021. The Issuers shall be entitled to issue Additional Notes
pursuant to Section 2.01 of the Indenture. The Notes and any Additional Notes issued under the Indenture shall be treated as a single class of securities under the Indenture. The terms of the Notes include those stated in the Indenture and
those made part of the Indenture by reference to the Trust Indenture Act of 1939, as amended (the “Trust Indenture Act”). The Notes are subject to all such terms, and Holders are referred to the Indenture and such Act for a
statement of such terms. To the extent any provision of this Note conflicts with the express provisions of the Indenture, the provisions of the Indenture shall govern and be controlling. 

5. OPTIONAL REDEMPTION. 
 The
Notes are not subject to optional redemption except as set forth below in this Section 5: 
 (a) At any time prior to
February 15, 2016, the Notes may be redeemed or purchased (by the Issuers or any other Person) at a redemption price equal to 100% of the principal amount of the Notes redeemed plus the Applicable Premium as of the date of redemption (the
“Redemption Date”), and, without duplication, accrued and unpaid interest to, but not including, the Redemption Date, subject to the rights of Holders on the relevant record date to receive interest due on the relevant interest
payment date. Such redemption or purchase may be made upon notice mailed by first-class mail to each Holder’s registered address (or otherwise delivered in accordance with the applicable DTC procedures), not less than 30 nor more than 60 days
prior to the Redemption Date. The Issuers may provide in such notice that payment of the redemption price and performance of the Issuers’ obligations with respect to such redemption or purchase may be performed by another Person. The Trustee
shall have no duty to calculate or verify the calculation of the Applicable Premium. 
 (b) On and after February 15,
2016, the Notes may be redeemed, at the Issuers’ option, in whole or in part, at any time and from time to time at the redemption prices set forth below. Such redemption may be made upon notice mailed by first-class mail to each Holder’s
registered address (or otherwise delivered in accordance with the applicable DTC procedures), not less than 30 nor more than 60 days prior to the Redemption Date. The Issuers may provide in such notice that the payment of the redemption price and
the performance of the Issuers’ obligations with respect to such redemption may be performed by another Person. The Notes will be redeemable at the redemption prices (expressed as percentages of principal amount of the Notes to be redeemed) set
forth below plus accrued and unpaid interest thereon to, but not including, the applicable Redemption Date, subject to the right of Holders of record on the relevant record date to receive interest due on the relevant interest payment date, if
redeemed during the twelve-month period beginning on February 15 of each of the years indicated below:

interest. The Holders of a majority in aggregate principal amount of the Notes then outstanding by notice to the Trustee may on behalf of the Holders of all of the Notes waive any existing Default or and its consequences under the Indenture except a
continuing Default in payment of the principal of, premium, if any, or interest on, any of the Notes held by a non-consenting Holder. Milacron is required to deliver to the Trustee annually a statement regarding compliance with the Indenture, and

W I T N E S S E T H 

WHEREAS, Milacron LLC, a Delaware limited liability company (“Milacron”) and Mcron Finance Corp., a Delaware corporation (the
“Co-Issuer” and together with Milacron, the “Issuers”), and the Guarantors (as defined in the Indenture referred to below) have heretofore executed and delivered to the Trustee an Indenture, dated as of
March 28, 2013 (as amended, further supplemented, waived or otherwise modified from time to time, the “Indenture”), providing for, among other things, the issuance of an unlimited aggregate principal amount of 7.750% Senior
Notes due 2021 (the “Notes”); 
 WHEREAS, Section 10.03 of the Indenture provides that the Guaranteeing Subsidiary
shall execute and deliver to the Trustee a supplemental indenture pursuant to which the Guaranteeing Subsidiary shall unconditionally guarantee all of the Issuers’ Obligations under the Notes and the Indenture (the “Guarantee”)
on the terms and conditions set forth herein and in Article X of the Indenture; and 
 WHEREAS, pursuant to Section 9.01 of the
Indenture, the Trustee is authorized to execute and deliver this Supplemental Indenture. 
 NOW THEREFORE, in consideration of the foregoing
and for other good and valuable consideration, the receipt of which is hereby acknowledged, the parties mutually covenant and agree, for the benefit of the Holders of the Notes, as follows: 

1. Defined Terms. As used in this Supplemental Indenture, terms defined in the Indenture or in the preamble or recital hereto are used
herein as therein defined. The words “herein,” “hereof” and “hereby” and other words of similar import used in this Supplemental Indenture refer to this Supplemental Indenture as a whole and not to any particular
section hereof. 
 2. Agreement to Guarantee. The Guaranteeing Subsidiary hereby agrees as follows: 

(a) Along with all other Guarantors named in the Indenture (including pursuant to any supplemental indentures), to jointly and
severally, unconditionally guarantee to each Holder of a Note authenticated and delivered by the Trustee and to the Trustee and its successors and assigns, that: 

(i) the principal of and interest and premium, if any, on the Notes shall be promptly paid in full when due, whether at
maturity, by acceleration, redemption or otherwise, and interest on the overdue principal of and interest on the Notes, if any, if lawful, and all other obligations of the Issuers to the Holders or the Trustee under the Indenture shall be promptly
paid in full or performed, all in accordance with the terms of the Indenture; and 
 (ii) in case of any extension of time of
payment or renewal of any Notes or any of such other obligations, that same shall be promptly paid in full when due or performed in accordance with the terms of the extension or renewal, whether at stated maturity, by acceleration or otherwise.
Failing payment when due of any amount so guaranteed or any performance so guaranteed for whatever reason, the Guarantors and the Guaranteeing Subsidiary shall be jointly and severally obligated to pay the same immediately. This is a guarantee of
payment and not a guarantee of collection. 

  
 D-1 








 (b) The obligations hereunder shall be unconditional, irrespective of the
validity, regularity or enforceability of the Notes or the Indenture or the obligations of the Issuers hereunder or thereunder, the absence of any action to enforce the same, any waiver or consent by any Holder of the Notes with respect to any
provisions hereof or thereof, the recovery of any judgment against the Issuers or any other Guarantor, any action to enforce the same or any other circumstance which might otherwise constitute a legal or equitable discharge or defense of a
guarantor. 
 (c) The Guaranteeing Subsidiary hereby waives diligence, presentment, demand of payment, filing of claims with
a court in the event of insolvency or bankruptcy of the Issuers, any right to require a proceeding first against the Issuers, protest, notice and all demands whatsoever. 

(d) This Guarantee shall not be discharged except by complete performance of the obligations contained in the Notes, the
Indenture and this Supplemental Indenture. The Guaranteeing Subsidiary accepts all obligations applicable to a Guarantor under the Indenture, including Article X of the Indenture (which is deemed incorporated in this Supplemental Indenture and
applicable to this Guarantee) and, as applicable, Sections 5.01(c) and (d) and Section 5.02 of the Indenture. The Guaranteeing Subsidiary acknowledges that by executing this Supplemental Indenture, it will become a Guarantor under the
Indenture and subject to all the terms and conditions applicable to Guarantors contained therein. 
 (e) If any Holder or the
Trustee is required by any court or otherwise to return to the Issuers, the Guarantors (including the Guaranteeing Subsidiary), or any custodian, trustee, liquidator or other similar official acting in relation to either the Issuers or the
Guarantors, any amount paid either to the Trustee or such Holder, this Guarantee, to the extent theretofore discharged, shall be reinstated in full force and effect. 

(f) The Guaranteeing Subsidiary shall not be entitled to any right of subrogation in relation to the Holders in respect of any
obligations guaranteed hereby until payment in full of all obligations guaranteed hereby. 
 (g) As between the Guaranteeing
Subsidiary, on the one hand, and the Holders and the Trustee, on the other hand, (x) the maturity of the obligations guaranteed hereby may be accelerated as provided in Article VI of the Indenture for the purposes of this Guarantee,
notwithstanding any stay, injunction or other prohibition preventing such acceleration in respect of the obligations guaranteed hereby, and (y) in the event of any declaration of acceleration of such obligations as provided in Article VI of the
Indenture, such obligations (whether or not due and payable) shall forthwith become due and payable by 
 the Guaranteeing
Subsidiary for the purpose of this Guarantee. 
 (h) The Guaranteeing Subsidiary shall have the right to seek contribution
from any nonpaying Guarantor so long as the exercise of such right does not impair the rights of the Holders under this Guarantee.

such other Guarantor under Article X of the Indenture, this new Guarantee shall be limited to the maximum amount permissible such that the obligations of such Guaranteeing Subsidiary under this Guarantee will not constitute a fraudulent transfer or
conveyance.

Notes and Guarantee, whether as a “voidable preference,” “fraudulent transfer” or otherwise, all as though such payment or performance had not been made. In the event that any payment or any part thereof is rescinded, reduced,
restored or returned, the Note shall, to the fullest extent permitted by law, be reinstated and deemed reduced only by such amount paid and not so rescinded, reduced, restored or returned. 

(k) In case any provision of this Guarantee shall be invalid, illegal or unenforceable, the validity, legality, and
enforceability of the remaining provisions shall not in any way be affected or impaired thereby.

transactions, to any Person.

as applicable, is merged or to which such sale, assignment, transfer, lease, conveyance or other disposition is made shall succeed to, and be substituted for (so that from and after the date of such consolidation, merger, sale, lease, conveyance or
other disposition, the provisions of the Indenture referring to such Issuer or Guarantor, as applicable, shall refer instead to the successor corporation and not to such Issuer or Guarantor, as applicable), and may exercise every right and power of

the Indenture.

Supplemental Indenture or for any claim based on, in respect of, or by reason of, such obligations or their creation. Each Holder by accepting Notes waives and releases all such liability. The waiver and release are part of the consideration for
