Exhibit 4.9

OPLINK COMMUNICATIONS, INC.

AMENDED AND RESTATED 2000 EMPLOYEE STOCK PURCHASE PLAN

     1. Purpose.

          (a) The purpose of this Amended and Restated 2000 Employee Stock Purchase Plan (the “Plan”) is
to provide a means by which employees of Oplink Communications, Inc. (the “Company”) and its
Affiliates, as defined in subparagraph 1(b), which are designated as provided in subparagraph 2(b),
may be given an opportunity to purchase common stock of the Company (the “Common Stock”).

          (b) The word “Affiliate” as used in the Plan means any parent corporation or subsidiary
corporation of the Company, as those terms are defined in Sections 424(e) and (f), respectively, of
the Internal Revenue Code of 1986, as amended (the “Code”).

          (c) The Company, by means of the Plan, seeks to retain the services of its employees, to
secure and retain the services of new employees, and to provide incentives for such persons to
exert maximum efforts for the success of the Company.

          (d) The Company intends that the rights to purchase stock of the Company granted under the
Plan be considered options issued under an “employee stock purchase plan” as that term is defined
in Section 423(b) of the Code.

     2. Administration.

          (a) The Plan shall be administered by the Board of Directors (the “Board”) of the Company
unless and until the Board delegates administration to a Committee, as provided in subparagraph
2(c). Whether or not the Board has delegated administration, the Board shall have the final power
to determine all questions of policy and expediency that may arise in the administration of the
Plan.

          (b) The Board shall have the power, subject to, and within the limitations of, the express
provisions of the Plan:

               (i) To determine when and how rights to purchase stock of the Company shall be granted and the
provisions of each offering of such rights (which need not be identical).

               (ii) To designate from time to time which Affiliates of the Company shall be eligible to
participate in the Plan.

               (iii) To construe and interpret the Plan and rights granted under it, and to establish, amend
and revoke rules and regulations for its administration. The Board, in the exercise of this power,
may correct any defect, omission or inconsistency in the Plan, in a manner and to the extent it
shall deem necessary or expedient to make the Plan fully effective.

               (iv) To amend the Plan as provided in paragraph 13.

               (v) To terminate or suspend the Plan as provided in paragraph 15.

               (vi) Generally, to exercise such powers and to perform such acts as the Board deems necessary
or expedient to promote the best interests of the Company and its Affiliates and to carry out the
intent that the Plan be treated as an “employee stock purchase plan” within the meaning of Section
423 of the Code.

 

 

          (c) The Board may delegate administration of the Plan to a Committee composed of not fewer
than two (2) members of the Board (the “Committee”). If administration is delegated to a Committee,
the Committee shall have, in connection with the administration of the Plan, the powers theretofore
possessed by the Board, subject, however, to such resolutions, not inconsistent with the provisions
of the Plan, as may be adopted from time to time by the Board. The Board may abolish the Committee
at any time and revest in the Board the administration of the Plan.

     3. Shares Subject To The Plan.

          (a) Subject to the provisions of paragraph 13 relating to adjustments upon changes in
securities, the shares of the Common Stock that may be sold pursuant to rights granted under the
Plan shall not exceed in the aggregate 2,857,142 shares of Common Stock. If any right granted under
the Plan shall for any reason terminate without having been exercised, the shares of the Common
Stock not purchased under such right shall again become available for the Plan.

          (b) The stock subject to the Plan may be unissued shares or reacquired shares, bought on the
market or otherwise.

     4. Grant Of Rights; Offering.

          The Board or the Committee may from time to time grant or provide for the grant of rights to
purchase Common Stock of the Company under the Plan to eligible employees (an “Offering”) on a date
or dates (the “Offering Date(s)”) selected by the Board or the Committee. Each Offering shall be in
such form and shall contain such terms and conditions as the Board or the Committee shall deem
appropriate, which shall comply with the requirements of Section 423(b)(5) of the Code that all
employees granted rights to purchase stock under the Plan shall have the same rights and
privileges. The terms and conditions of an Offering shall be incorporated by reference into the
Plan and treated as part of the Plan. The provisions of separate Offerings need not be identical,
but each Offering shall include (through incorporation of the provisions of this Plan by reference
in the document comprising the Offering or otherwise) the period during which the Offering shall be
effective, which period shall not exceed twenty-seven (27) months beginning with the Offering Date,
and the substance of the provisions contained in paragraphs 5 through 8, inclusive.

     5. Eligibility.

          (a) Rights may be granted only to employees of the Company or, as the Board or the Committee
may designate as provided in subparagraph 2(b), to employees of any Affiliate of the Company.
Except as provided in subparagraph 5(b), an employee of the Company or any Affiliate shall not be
eligible to be granted rights under the Plan unless, on the Offering Date, such employee has been
in the employ of the Company or any Affiliate for such continuous period preceding such grant as
the Board or the Committee may require, but in no event shall the required period of continuous
employment be greater than two (2) years. In addition, unless otherwise determined by the Board or
the Committee and set forth in the terms of the applicable Offering, no employee of the Company or
any Affiliate shall be eligible to be granted rights under the Plan unless, on the Offering Date,
such employee’s customary employment with the Company or such Affiliate is for at least twenty (20)
hours per week and at least five (5) months per calendar year.

          (b) The Board or the Committee may provide that each person who, during the course of an
Offering, first becomes an eligible employee of the Company or designated Affiliate will, on a date
or dates specified in the Offering, which date coincides with the day on which such person becomes
an eligible employee or occurs thereafter, receive a right under that Offering, which right shall
thereafter be deemed to be a part of that Offering. Such right shall have the same characteristics
as any rights originally granted under that Offering, as described herein, except that:

               (i) the date on which such right is granted shall be the “Offering Date” of such right for all
purposes, including determination of the exercise price of such right;

-2-

 

               (ii) the period of the Offering with respect to such right shall begin on its Offering Date
and end coincident with the end of such Offering; and

               (iii) the Board or the Committee may provide that if such person first becomes an eligible
employee within a specified period of time before the end of the Offering, he or she will not
receive any right under that Offering.

          (c) No employee shall be eligible for the grant of any rights under the Plan if, immediately
after any such rights are granted, such employee owns stock possessing five percent (5%) or more of
the total combined voting power or value of all classes of stock of the Company or of any
Affiliate. For purposes of this subparagraph 5(c), the rules of Section 424(d) of the Code shall
apply in determining the stock ownership of any employee, and stock which such employee may
purchase under all outstanding rights and options shall be treated as stock owned by such employee.

          (d) An eligible employee may be granted rights under the Plan only if such rights, together
with any other rights granted under “employee stock purchase plans” of the Company and any
Affiliates, as specified by Section 423(b)(8) of the Code, do not permit such employee to purchase
stock of the Company or any Affiliate at a rate that exceeds twenty-five thousand dollars ($25,000)
of fair market value of such stock (determined at the time such rights are granted) for each
calendar year in which such rights are outstanding at any time, as determined in accordance with
Section 423 of the Code and the regulations thereunder.

          (e) Officers of the Company and any designated Affiliate shall be eligible to participate in
Offerings under the Plan; provided, however, that the Board may provide in an Offering that certain
employees who are highly compensated employees within the meaning of Section 423(b)(4)(D) of the
Code shall not be eligible to participate.

     6. Rights; Purchase Price.

          (a) On each Offering Date, each eligible employee, pursuant to an Offering made under the
Plan, shall be granted the right to purchase up to that number of shares of Common Stock of the
Company purchasable with up to twenty percent (20%) (or such lower percentage as may be designated
by the Board or Committee) of such employee’s Earnings (as defined in subparagraph 7(a)) during the
period which begins on the Offering Date (or such later date as the Board or the Committee
determines for a particular Offering) and ends on the date stated in the Offering, which date shall
be no later than the end of the Offering. The Board or the Committee shall establish one or more
dates during an Offering (the “Purchase Date(s)”) on which rights granted under the Plan shall be
exercised and purchases of Common Stock carried out in accordance with such Offering.

          (b) In connection with each Offering made under the Plan, the Board or the Committee may
specify a maximum number of shares that may be purchased by any employee as well as a maximum
aggregate number of shares that may be purchased by all eligible employees pursuant to such
Offering. In addition, in connection with each Offering that contains more than one Purchase Date,
the Board or the Committee may specify a maximum aggregate number of shares that may be purchased
by all eligible employees on any given Purchase Date under the Offering. If the aggregate number of
shares issuable upon exercise of rights granted under the Offering would exceed any such maximum
aggregate number, the Board or the Committee shall make a pro rata allocation of the shares
available in as nearly a uniform manner as shall be practicable and as it shall deem to be
equitable. Unless and until the Board or the Committee provide otherwise, in no event will an
eligible employee be permitted to purchase more than 25,000 shares of the Common Stock on any one
Purchase Date (subject to any adjustment pursuant to Section 12) and any such purchase will be
subject to the limitations set forth in Sections 5. The Board or the Committee may, for future
Offerings, increase or decrease, in its absolute discretion, the maximum number of shares of Common
Stock that an eligible employee may purchase on any Purchase Date.

          (c) The purchase price of stock acquired pursuant to rights granted under the Plan shall be
not less than the lesser of:

-3-

 

               (i) an amount equal to eighty-five percent (85%) of the fair market value of the stock on the
Offering Date; or

               (ii) an amount equal to eighty-five percent (85%) of the fair market value of the stock on the
Purchase Date.

          Fair market value will be determined by the Board or the Committee, as of any date, by
reference to the price of Common Stock on any established stock exchange or a national market
system on the day of determination if the Common Stock is so listed on any established stock
exchange or a national market system. If the Common Stock is not listed on any established stock
exchange or a national market system, the value of the Common Stock as the Board or the Committee
may determine in good faith.

     7. Participation; Withdrawal; Termination.

          (a) An eligible employee may become a participant in the Plan pursuant to an Offering by
delivering a participation agreement to the Company within the time specified in the Offering, in
such form as the Company provides. Each such agreement shall authorize payroll deductions of up to
the maximum percentage specified by the Board or the Committee of such employee’s Earnings during
the Offering. “Earnings” is defined as an employee’s wages (including amounts thereof elected to be
deferred by the employee, that would otherwise have been paid, under any arrangement established by
the Company that is intended to comply with Section 125, 401(k), 402(h) or 403(b) of the Code or
that provides non-qualified deferred compensation), overtime pay, bonuses, incentive pay,
commissions and other remuneration paid directly to the employee, but excluding profit sharing, the
cost of employee benefits paid for by the Company or an Affiliate, education or tuition
reimbursements, imputed income arising under any group insurance or benefit program, traveling
expenses, business and moving expense reimbursements, income received in connection with stock
options, contributions made by the Company or an Affiliate under any employee benefit plan, and
similar items of compensation, as determined by the Board or the Committee. The payroll deductions
made for each participant shall be credited to an account for such participant under the Plan and
shall be deposited with the general funds of the Company. A participant may reduce (including to
zero) or increase such payroll deductions, and an eligible employee may begin such payroll
deductions, after the beginning of any Offering only as provided for in the Offering. A
participant may make additional payments into his or her account only if specifically provided for
in the Offering and only if the participant has not had the maximum amount withheld during the
Offering.

          (b) At any time during an Offering, a participant may terminate his or her payroll deductions
under the Plan and withdraw from the Offering by delivering to the Company a notice of withdrawal
in such form as the Company provides. Such withdrawal may be elected at any time prior to the end
of the Offering except as provided by the Board or the Committee in the Offering. Upon such
withdrawal from the Offering by a participant, the Company shall distribute to such participant all
of his or her accumulated payroll deductions (reduced to the extent, if any, such deductions have
been used to acquire stock for the participant) under the Offering, without interest, and such
participant’s interest in that Offering shall be automatically terminated. A participant’s
withdrawal from an Offering will have no effect upon such participant’s eligibility to participate
in any other Offerings under the Plan but such participant will be required to deliver a new
participation agreement in order to participate in subsequent Offerings under the Plan.

          (c) Rights granted pursuant to any Offering under the Plan shall terminate immediately upon
cessation of any participating employee’s employment with the Company and any designated Affiliate,
for any reason, and the Company shall distribute to such terminated employee all of his or her
accumulated payroll deductions (reduced to the extent, if any, such deductions have been used to
acquire stock for the terminated employee), under the Offering, without interest.

          (d) Right granted under the Plan shall not be transferable by a participant otherwise than by
will or the laws of descent and distribution, or by a beneficiary designation as provided in
paragraph 14 and, otherwise during his or her lifetime, shall be exercisable only by the person to
whom such rights are granted.

     8. Exercise.

-4-

 

          (a) On each Purchase Date specified in the relevant Offering, each participant’s accumulated
payroll deductions and other additional payments specifically provided for in the Offering (without
any increase for interest) will be applied to the purchase of whole shares of stock of the Company,
up to the maximum number of shares permitted pursuant to the terms of the Plan and the applicable
Offering, at the purchase price specified in the Offering. No fractional shares shall be issued
upon the exercise of rights granted under the Plan. The amount, if any, of accumulated payroll
deductions remaining in each participant’s account after the purchase of shares that is less than
the amount required to purchase one share of stock on the final Purchase Date of an Offering shall
be held in each such participant’s account for the purchase of shares under the next Offering under
the Plan, unless such participant withdraws from such next Offering, as provided in subparagraph
7(b), or is no longer eligible to be granted rights under the Plan, as provided in paragraph 5, in
which case such amount shall be distributed to the participant after such final Purchase Date,
without interest. Any amount of accumulated payroll deductions remaining in a participant’s account
after the purchase of shares that equals or exceeds the amount required to purchase a whole share
of stock on the final Purchase Date of an Offering shall be distributed in full to the participant
after such Purchase Date, without interest.

          (b) No rights granted under the Plan may be exercised to any extent unless the shares to be
issued upon such exercise under the Plan are covered by an effective registration statement
pursuant to the Securities Act of 1933, as amended (the “Securities Act”) and the Plan is in
material compliance with all applicable state, foreign and other securities and other laws
applicable to the Plan. If, on the Purchase Date of any Offering hereunder, the shares to be issued
under the Plan are not so registered or the Plan is not in such compliance, no rights granted under
the Plan or any Offering shall be exercised on such Purchase Date. If, on the Purchase Date of any
Offering hereunder, such shares are not registered and the Plan is not in such compliance, no
rights granted under the Plan or any Offering shall be exercised and all payroll deductions
accumulated during the Offering (reduced to the extent, if any, such deductions have been used to
acquire stock) shall be distributed to the participants, without interest.

     9. Covenants of the Company.

          (a) During the terms of the rights granted under the Plan, the Company shall keep available at
all times the number of shares of stock required to satisfy such rights.

          (b) The Company shall seek to obtain from each federal, state, foreign or other regulatory
commission or agency having jurisdiction over the Plan such authority as may be required to issue
and sell shares of stock upon exercise of the rights granted under the Plan. If, after reasonable
efforts, the Company is unable to obtain from any such regulatory commission or agency the
authority which counsel for the Company deems necessary for the lawful issuance and sale of stock
under the Plan, the Company shall be relieved of any liability for failure to issue and sell stock
upon exercise of such rights unless and until such authority is obtained.

     10. Use of Proceeds From Stock.

          Proceeds from the sale of stock pursuant to rights granted under the Plan shall constitute
general funds of the Company.

     11. Rights as a Stockholder.

          A participant shall not be deemed to be the holder of, or to have any of the rights of a
holder with respect to, any shares subject to rights granted under the Plan unless and until the
participant’s shares acquired upon exercise of rights under the Plan are recorded in the books of
the Company.

     12. Adjustments Upon Changes in Stock.

          (a) In the event that any dividend or other distribution (whether in the form of cash, Common
Stock, other securities, or other property), recapitalization, stock split, reverse stock split,
reorganization, merger, consolidation, split-up, spin-off, combination, repurchase, or exchange of
Common Stock or other securities of the Company, or other change in the corporate structure of the
Company affecting the Common Stock occurs, the

-5-

 

Board, in order to prevent dilution or enlargement of the benefits or potential benefits
intended to be made available under the Plan, will, in such manner as it may deem equitable, adjust
the number and class of Common Stock that may be delivered under the Plan, the purchase price per
share and the number of shares of Common Stock covered by each option under the Plan that has not
yet been exercised, and the numerical limits of Sections 3 and 6(b). Such adjustments shall be made
by the Board, the determination of which shall be final, binding and conclusive.

          (b) In the event of: (1) a dissolution or liquidation of the Company, (2) the sale of all or
substantially all of the securities or assets of the Company, (3) a merger or consolidation in
which the Company is not the surviving corporation or (4) a reverse merger in which the Company is
the surviving corporation but the shares of Common Stock outstanding immediately preceding the
merger are converted by virtue of the merger into other property, whether in the form of
securities, cash or otherwise, then any surviving corporation may assume outstanding rights or
substitute similar rights for those under the Plans. If no surviving corporation assumes
outstanding rights or substitutes similar rights therefor, the Offerings with respect to which such
rights relate will be shortened by setting a new Purchase Date on which such Offering shall end.
The new Purchase Date will occur before the date of the Company’s proposed transaction described
above. The Board will notify each participant in writing prior to the new Purchase Date, that the
Purchase Date for the participant’s option has been changed to the new Purchase Date and that the
participant’s right will be exercised automatically on the new Purchase Date, unless prior to such
date the participant has withdrawn from the Offering.

     13. Amendment of the Plan.

          (a) The Board at any time, and from time to time, may amend the Plan. However, except as
provided in paragraph 12 relating to adjustments upon changes in stock, no amendment shall be
effective unless approved by the stockholders of the Company within twelve (12) months before or
after the adoption of the amendment, where the amendment will:

               (i) Increase the number of shares reserved for rights under the Plan;

               (ii) Modify the provisions as to eligibility for participation in the Plan (to the extent such
modification requires stockholder approval in order for the Plan to obtain employee stock purchase
plan treatment under Section 423 of the Code; or

               (iii) Modify the Plan in any other way if such modification requires stockholder approval in
order for the Plan to obtain employee stock purchase plan treatment under Section 423 of the Code.

          It is expressly contemplated that the Board may amend the Plan in any respect the Board deems
necessary or advisable to provide eligible employees with the maximum benefits provided or to be
provided under the provisions of the Code and the regulations promulgated thereunder relating to
employee stock purchase plans and/or to bring the Plan and/or rights granted under it into
compliance therewith.

          (b) Rights and obligations under any rights granted before amendment of the Plan shall not be
impaired by any amendment of the Plan, except (i) with the consent of the person to whom such
rights were granted, (ii) as necessary to comply with any laws or governmental regulations, or
(iii) as necessary to ensure that the Plan and/or rights granted under the Plan comply with the
requirements of Section 423 of the Code.

     14. Designation of Beneficiary.

          (a) A participant may file a written designation of a beneficiary who is to receive any shares
and cash, if any, from the participant’s account under the Plan in the event of such participant’s
death subsequent to the end of an Offering but prior to delivery to the participant of such shares
and cash. In addition, a participant may file a written designation of a beneficiary who is to
receive any cash from the participant’s account under the Plan in the event of such participant’s
death during an Offering.

          (b) Such designation of beneficiary may be changed by the participant at any time by written
notice. In the event of the death of a participant and in the absence of a beneficiary validly
designated under the Plan

-6-

 

who is living at the time of such participant’s death, the Company shall deliver such shares
and/or cash to the executor or administrator of the estate of the participant, or if no such
executor or administrator has been appointed (to the knowledge of the Company), the Company, in its
sole discretion, may deliver such shares and/or cash to the spouse or to any one or more dependents
or relatives of the participant, or if no spouse, dependent or relative is known to the Company,
then to such other person as the Company may designate.

     15. Termination or Suspension of the Plan.

          (a) The Board in its discretion, may suspend or terminate the Plan at any time. No rights may
be granted under the Plan while the Plan is suspended or after it is terminated.

          (b) Rights and obligations under any rights granted while the Plan is in effect shall not be
altered or impaired by suspension or termination of the Plan, except (i) as expressly provided in
the Plan or with the consent of the person to whom such rights were granted, (ii) as necessary to
comply with any laws or governmental regulation, or (iii) as necessary to ensure that the Plan
and/or rights granted under the Plan comply with the requirements of Section 423 of the Code.

          (c) Notwithstanding the foregoing, the Plan shall continue in effect unless terminated sooner
under this Section 15.

     16. Effective Date of Plan.

          The Plan was originally adopted by the Board in July 2000 and originally approved by the
stockholders of the Company in September 2000. The amendment and restatement of the Plan was
adopted by the Board on September 23, 2009, subject to, and effective upon, approval by the
stockholders of the Company at the 2009 Annual Meeting. Such stockholder approval will be obtained
in the manner and to the degree required under applicable laws.

     17. Automatic Transfer to Low Price Offering Period.

          To the extent permitted by applicable laws, if the fair market value of the Common Stock on
any Purchase Date in an Offering is lower than the fair market value of the Common Stock on the
Offering Date of such Offering, then all participants in such Offering will be automatically
withdrawn from such Offering immediately after the exercise of their right on such Purchase Date
and automatically re-enrolled in the immediately following Offering.

    Secured Notes due 2016

 

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

 

    1. Interest.  Altra
    Holdings, Inc., a Delaware corporation (the
    “Company”), promises to pay interest on the
    principal amount of this Note at a rate of
    81/8%
    per annum until maturity [and shall pay the Additional Interest,
    if any, payable pursuant to Section 4 of the Registration
    Rights Agreement referred to below]. The Company will pay
    interest [and Additional Interest, if any,] semi-annually in
    arrears on December 1 and June 1 of each year, or if any such
    day is not a Business Day, on the next succeeding Business Day
    (each, an “Interest Payment Date”). Interest on
    the Notes will accrue from the most recent date to which
    interest has been paid or, if no interest has been paid, from
    the date of issuance; provided that if there is no
    existing Default in the payment of interest, and if this Note is
    authenticated between a record date referred to on the face
    hereof and the next succeeding Interest Payment Date, interest
    shall accrue from such next succeeding Interest Payment Date;
    provided further that the first Interest Payment Date
    shall
    be          ,
    20          .
    The Company will pay interest on overdue principal and premium
    [and Additional Interest, if any,] from time to time on demand
    at a rate that is 1% per annum in excess of the rate then in
    effect to the extent lawful; it will pay interest (including
    post-petition interest in any proceeding under any Bankruptcy
    Law) on overdue installments of interest [and Additional
    Interest, if any,] (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
    of twelve
    30-day
    months.

 

    2. Method of
    Payment.  The Company will pay interest on
    the Notes [and Additional Interest, if any,] to the Persons
    who are registered Holders of Notes at the close of business on
    the November 15 or May 15 next preceding the Interest Payment
    Date, even if such Notes are 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. The Notes will be payable as to principal, [and]
    premium [and Additional Interest, if any,] and interest at the
    office or agency of the Company maintained for such purpose
    within or without the City and State of New York, or, at the
    option of the Company, payment of interest [and Additional
    Interest, if any,] may be made by check mailed to the Holders at
    their addresses set forth in the register of Holders;
    provided that payment by wire transfer of immediately
    available funds will be required with respect to principal of
    and interest, [and] premium [and Additional Interest, if any,]
    on, all Global Notes and all other Notes the Holders of which
    will have provided wire transfer instructions to the Company or
    the Paying Agent. Such payment will 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, The Bank of New
    York Mellon Trust Company, N.A., the Trustee and Collateral
    Agent under the Indenture, will act as Paying Agent and
    Registrar. The Company may change any Paying Agent or Registrar
    without notice to any Holder. The Company or any of its
    Subsidiaries may act in any such capacity.

 

    4. Indenture.  The
    Company issued the Notes under an Indenture dated as of
    November 25, 2009 (the “Indenture”) among
    the Company, the Guarantors and the Trustee and Collateral
    Agent. The terms of the Notes include those stated in the
    Indenture and those made part of the Indenture by reference to
    the TIA. The Notes are subject to all such terms, and Holders
    are referred to the Indenture and the TIA 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. The Notes are
    secured obligations of the Company. Each Holder, by accepting a
    Note, agrees to be bound by all of the terms and provisions of
    the Indenture, as the same may be amended from time to time.

 

    5. Optional
    Redemption. 

 

    (a) At any time prior to December 1, 2012, the Company
    may on any one or more occasions redeem up to 35% of the
    aggregate principal amount of Notes issued under this Indenture
    at a redemption price equal to 108.125% of the principal amount
    of the Notes redeemed, plus accrued and unpaid interest [and
    Additional Interest, if any,] to the date of redemption (subject
    to the rights of Holders of Notes on the relevant regular record
    date to receive interest

    (A) at least 65% of the aggregate principal amount of Notes
    originally issued under this Indenture (excluding Notes held by
    the Company and its Subsidiaries and any Notes redeemed under
    Paragraph 5(c)) remains outstanding immediately after the
    occurrence of such redemption; and

 

    (B) the redemption occurs within 90 days of the date
    of the closing of such Equity Offering by the Company.

 

    (b) On or after December 1, 2012, the Company may on

    set forth below, plus accrued and unpaid interest [and

    %

 

    (c) During each twelve-month period ending on
    December 1, 2010, 2011 and 2012, the Company may redeem up
    to 10% of the originally issued principal amount of Notes, upon
    not less than 30 nor more than 60 days’ prior notice
    mailed by first-class mail to the registered address of each
    Holder of Notes or otherwise in accordance with the procedures
    of DTC, at a redemption price equal to 103% of the principal
    amount of the Notes redeemed and accrued and unpaid interest
    [and Additional Interest, if any,] to the redemption date,
    subject to the rights of Holders of Notes on the relevant record
    date to receive interest due on the relevant interest payment
    date.

 

    (d) Notwithstanding the foregoing, at any time prior to
    December 1, 2012, the Company may also redeem all or a part
    of the Notes, upon not less than 30 nor more than
    60 days’ notice, mailed by first-class mail to each
    Holder’s registered address, at a redemption price equal to
    100% of the principal amount of the Notes redeemed plus the
    Applicable Premium as of, and accrued and unpaid interest [and
    Additional Interest, if any,] on the Notes redeemed, to the date
    of redemption, subject to the rights of Holders of Notes on the
    relevant record date to receive interest due on the relevant

    (e) Except pursuant to Paragraphs 5(a),(c) and (d),
    the Notes will not be redeemable at the Company’s option
    prior to December 1, 2012.

 

    (f) Unless the Company defaults in the payment of the
    redemption price, interest will cease to accrue on the Notes or
    portions thereof called for redemption on the applicable
    redemption date.

 

    6. No Mandatory
    Redemption.  The Company is not required to
    make mandatory redemption or sinking fund payments with respect
    to the Notes.

 

    7. Repurchase at the
    Option of Holder.

 

      (a) If there is
    a Change of Control, the Company will make an offer (a
    “Change of Control Offer”) to each Holder to
    repurchase all or any part (equal to $2,000 or an integral
    multiple of $1,000 thereof) of each Holder’s Notes at a
    purchase price in cash equal to 101% of the aggregate principal
    amount thereof plus accrued and unpaid interest [and Additional
    Interest, if any,] thereon to the date of purchase, subject to
    the rights of Holders on the relevant record date to receive
    interest due on the relevant interest payment date (the
    “Change of Control Payment”). Within
    30 days following any Change of Control, the Company will
    mail a notice to each Holder describing the transaction or
    transactions that constitute the Change of Control and offering
    to repurchase Notes on the Change of Control Payment Date
    specified in the notice, which date will be no earlier than
    30 days and no later than 60 days from the date such
    notice is mailed, pursuant to the procedures required by the
    Indenture and described in such notice.

    (b) If the Company or a Restricted Subsidiary of the
    Company consummates any Asset Sales, within 30 days of each
    date on which the aggregate amount of Excess Proceeds exceeds
    $15.0 million, the Company will make an offer to all
    Holders of Notes and all holders of other Indebtedness that is
    pari passu with the Notes containing provisions similar
    to those set forth in the Indenture with respect to offers to
    purchase, prepay or redeem the maximum principal amount of notes
    and such other pari passu Indebtedness that may be
    purchased, prepaid or redeemed out of the Excess Proceeds (an
    “Asset Sale Offer”) pursuant to Section 3.09 of
    the Indenture to purchase the maximum principal amount of Notes
    and such other pari passu Indebtedness that may be
    purchased out of the Excess Proceeds at an offer price in cash
    in an amount equal to 100% of the principal amount thereof plus
    accrued and unpaid interest [and Additional Interest, if any,]
    thereon to the date of purchase, prepayment or redemption, in
    accordance with the procedures set forth in the Indenture. To
    the extent that the aggregate amount of Notes and other pari
    passu Indebtedness tendered pursuant to an Asset Sale Offer
    is less than the Excess Proceeds, the Company may use such
    remaining Excess Proceeds for any purpose not otherwise
    prohibited by the Indenture. If the aggregate principal amount
    of Notes and other pari passu Indebtedness tendered into
    such Asset Sale Offer exceeds the amount of Excess Proceeds, the
    Trustee shall select the Notes to be purchased on a pro rata
    basis. Holders of Notes that are the subject of an offer to
    purchase will receive an Asset Sale Offer from the Company prior
    to any related purchase date and may elect to have such Notes
    purchased by completing the form entitled “Option of
    Holder to Elect Purchase” attached to the Notes.

 

    8. Security.  The
    obligations of the Company and the Guarantors under the Notes
    and the Guarantees are secured by Liens on the Collateral
    pursuant to the terms of the Collateral Documents. The actions
    of the Trustee, the Collateral Agent and the Holders secured by
    such Liens and the application of proceeds from the enforcement
    of any remedies with respect to such Collateral are limited
    pursuant to the Collateral Documents.

 

    9. Intercreditor
    Acknowledgment.  The lien and security
    interest evidenced by this Note and the exercise of any right or
    remedy by any Holder in respect thereof is junior and
    subordinate to the interest of JPMorgan Chase Bank, N.A.,
    individually and as Senior Agent and is subject to the
    provisions of that certain Intercreditor and Lien Subordination
    Agreement, dated as of November 25, 2009, as amended,
    supplemented, modified or replaced from time to time in
    accordance with the terms thereof among JPMorgan Chase Bank,
    N.A., as Senior Agent, The Bank of New York Mellon
    Trust Company, N.A., as Trustee and Collateral Agent, the
    Company, Altra Industrial Motion, Inc. and certain of the
    Company’s Subsidiaries.

 

    10. Notice of
    Redemption.  Notice of redemption will be
    mailed at least 30 days but not more than 60 days
    before the redemption date to each Holder of Notes to be
    redeemed at its registered address, except that redemption
    notices may be mailed more than 60 days prior to a
    redemption date if the notice is issued in connection with a
    defeasance of the Notes or a satisfaction or discharge of the
    Indenture. Notes and portions of Notes selected will be in
    minimum amounts of $2,000 and integral multiples of $1,000;
    except that if all of the Notes of a Holder are to be redeemed
    or purchased, the entire outstanding amount of Notes held by
    such Holder, even if not a multiple of $1,000, shall be redeemed
    or purchased.

 

    11. Denominations,
    Transfer, Exchange.  The Notes are in
    registered form without coupons in denominations of $2,000 and
    integral multiples of $1,000 in excess thereof. The transfer of
    Notes may be registered and Notes may be exchanged as provided
    in the Indenture. The Registrar and the Trustee may require a
    Holder, among other things, to furnish appropriate endorsements
    and transfer documents and the Company may require a Holder to
    pay any taxes and fees required by law or permitted by the
    Indenture. The Company need not exchange or register the
    transfer of any Note or portion of a Note selected for
    redemption, except for the unredeemed portion of any Note being
    redeemed in part. Also, the Company need not exchange or
    register the transfer of any Notes for a period of 15 days
    before a selection of Notes to be redeemed or during the period
    between a record date and the corresponding Interest Payment
    Date.

 

    12. Persons
    Deemed Owners.  The registered Holder of a
    Note may be treated as its owner for all purposes.

 

    13. Amendment,
    Supplement and Waiver.  Subject to certain
    exceptions, the Indenture, the Notes, the Note Guarantees, and
    the Collateral Documents (including, with the consent of the
    required lenders under the Credit Facilities, the Intercreditor
    Agreement) may be amended or supplemented with the consent of
    the Holders of at least a majority in aggregate principal amount
    of the Notes then outstanding (including, without limitation,
    consents obtained in connection with a purchase of, or tender
    offer or exchange offer for, Notes), and any existing Default or

    

    8

 

    Event or Default or compliance with any provision of the
    Indenture, the Notes and the Note Guarantees may be waived with
    the consent of the Holders of a majority in aggregate principal
    amount of the then outstanding Notes (including, without
    limitation, consents obtained in connection with a purchase of,
    or tender offer or exchange offer for, Notes). Any amendment to,
    or waiver of, the provisions of the Indenture or any Collateral
    Document that has the effect of releasing all or substantially
    all of the Collateral from the Liens securing the Notes will
    require the consent of the Holders of at least
    662/3%
    in aggregate principal amount of the Notes then outstanding.

 

    Without the consent of any Holder of a Note, the Indenture, the
    Notes or the Note Guarantees may be amended or supplemented
    (i) to cure any ambiguity, defect or inconsistency;
    (ii) to provide for uncertificated Notes in addition to or
    in place of certificated Notes; (iii) to provide for the
    assumption of the Company’s or a Guarantor’s
    obligations to Holders of Notes and Note Guarantees in the case
    of a merger or consolidation or sale of all or substantially all
    of the Company’s or such Guarantor’s assets, as
    applicable; (iv) to make any change that would provide any
    additional rights or benefits to the Holders of Notes or that
    does not adversely affect the legal rights under this Indenture
    of any such Holder; (v) to comply with requirements of the
    SEC in order to effect or maintain the qualification of this
    Indenture under the TIA; (vi) to conform the text of this
    Indenture, the Note Guarantees, the Collateral Documents or the
    Notes to any provision of the “Description of Notes”
    section of the Offering Memorandum to the extent that such
    provision was intended by the Company to be a verbatim
    recitation of a provision of this Indenture, the Note
    Guarantees, the Collateral Documents or the Notes, which intent
    shall be evidenced by an Officers’ Certificate to that
    effect; (vii) to enter into additional or supplemental
    Collateral Documents; (vii) to release Collateral in
    accordance with the terms of this Indenture and the Collateral
    Documents; (ix) to provide for the issuance of Additional
    Notes in accordance with the limitations set forth in this
    Indenture as of the date of this Indenture; or (x) to allow
    any Guarantor to execute a supplemental indenture
    and/or a
    Note Guarantee with respect to the Notes.

 

    14. Defaults and
    Remedies.  The Events of Default relating
    to the Notes are defined in Section 6.01 of the Indenture.
    In the case of an Event of Default arising from certain events
    of bankruptcy or insolvency, with respect to the Company, any
    Restricted Subsidiary of the Company that is a Significant
    Subsidiary or any group of Restricted Subsidiaries of the
    Company that, taken together, would constitute a Significant
    Subsidiary, all outstanding Notes will become due and payable
    immediately without further action or notice. If any other Event
    of Default occurs and is continuing and has not been waived in
    accordance with the terms of this Indenture, the Trustee or the
    Holders of at least 25% in aggregate principal amount of the
    then outstanding Notes may declare all the Notes to be due and
    payable immediately. Holders may not enforce the Indenture or
    the Notes except as provided in the Indenture. Subject to
    certain limitations, Holders of a majority in aggregate
    principal amount of the then outstanding Notes may direct the
    Trustee in its exercise of any trust or power. The Trustee may
    withhold from Holders of the Notes notice of any continuing
    Default or Event of Default if it determines that withholding
    notice is in their interest, except a Default or Event of
    Default relating to the payment of principal or interest or
    premium [or Additional Interest, if any].

 

    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, rescind an acceleration or waive
    any existing Default or Event of Default and its consequences
    under the Indenture, except a continuing Default or Event of
    Default in the payment of interest or premium [or Additional
    Interest, if any,] on, or the principal of, the Notes. 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 the Indenture; but no such waiver shall extend
    to any subsequent or other Default or impair any right
    consequent thereon. The Company is required to deliver to the
    Trustee annually a statement regarding compliance with the
    Indenture, and the Company is required, upon becoming aware of
    any Default or Event of Default, to deliver to the Trustee a
    statement specifying such Default or Event of Default.

 

    15. [Registration
    Rights.  Pursuant to the Registration
    Rights Agreement, dated November 25, 2009 (the
    “Registration Rights Agreement”), among the
    Company, the Guarantors and the Initial Purchasers, the Company
    will be obligated to consummate an Exchange Offer. Upon such
    Exchange Offer, the Holders of Notes shall have the right,
    subject to compliance with securities laws, to exchange such
    Notes for Exchange Notes in like principal amount and having
    terms identical in all material respects to the Notes. The
    Holders of the Notes shall be entitled to receive certain
    Additional Interest in the event such exchange offer is not
    consummated and upon certain other conditions, all pursuant to
    and in accordance with the terms of the Registration Rights
    Agreement.]

    16. Trustee
    Dealings with Company.  The Trustee, in its
    individual or any other capacity, may make loans to, accept
    deposits from, and perform services for the Company or its
    Affiliates, and may otherwise deal with the Company or its
    Affiliates, as if it were not the Trustee.

 

    17. No Recourse
    Against Others.  A director, officer,
    employee, incorporator or stockholder or other owner of Capital
    Stock of the Company or any of the Guarantors, as such, will not
    have any liability for any obligations of the Company or the
    Guarantors under the Notes, the Note Guarantees or the Indenture
    or for any claim based on, in respect of, or by reason of, such
    obligations or their creation. Each Holder by accepting a Note
    waives and releases all such liability. The waiver and release
    are part of the consideration for the issuance of the Notes.

 

    18. Authentication.  This
    Note will not be valid until authenticated by the manual
    signature of the Trustee or an authenticating agent.

 

    19. Abbreviations.  Customary
    abbreviations may be used in the name of a Holder or an
    assignee, such as: TEN COM (= tenants in common), TEN ENT (=
    tenants by the entireties), JT TEN (= joint tenants with right
    of survivorship and not as tenants in common), CUST (=
    Custodian), and U/G/M/A (= Uniform Gifts to Minors Act).

    Rights of Holders of Restricted Global Notes and Restricted
    Definitive Notes.  In addition to the
    rights provided to Holders of Notes under the Indenture, Holders
    of Restricted Global Notes and Restricted Definitive Notes will
    have all the rights set forth in the Registration Rights
    Agreement.

 

    21. CUSIP
    Numbers.  Pursuant to a recommendation
    promulgated by the Committee on Uniform Security Identification
    Procedures, the Company has caused CUSIP numbers to be printed
    on the Notes, and the Trustee may use CUSIP numbers in notices
    of redemption as a convenience to Holders. No representation is
    made as to the accuracy of such numbers either as printed on the
    Notes or as contained in any notice of redemption, and reliance
    may be placed only on the other identification numbers placed
    thereon.

 

    22. GOVERNING
    LAW.   THE INTERNAL LAW OF THE STATE OF NEW
    YORK WILL GOVERN AND BE USED TO CONSTRUE THE INDENTURE, THIS
    NOTE AND THE NOTE GUARANTEES WITHOUT GIVING EFFECT TO
    APPLICABLE PRINCIPLES OF CONFLICTS OF LAW TO THE EXTENT THAT THE
    APPLICATION OF THE LAWS OF ANOTHER JURISDICTION WOULD BE
    REQUIRED THEREBY.

 

    The Company will furnish to any Holder upon written request and
    without charge a copy of the Indenture
    and/or the
    Registration Rights Agreement. Requests may be made to:

    requested to confirm that such transfer is being made pursuant
    to an exemption from, or in a transaction not subject to, the
    registration requirements of the Securities Act.

 

    If none of the foregoing boxes is checked, the Trustee or
    Registrar shall not be obligated to register this Note in the
    name of any person other than the Holder hereof unless and until
