       collateralization of all Letters of Credit (as defined in the Loan and
       Security Agreement) in accordance with the subordination provisions of

       entitled to under Section 4.2 of the Certificate of Designations but for
       the provisions of this Section 2.6(b) and the subordination provisions of
       Exhibit E hereto, it being understood and agreed that such holders shall

       in an exchange of a majority of the Common Stock of the Company for cash,
       cash equivalents or other securities or property;

                     (C) any public offering of equity securities of the

       promptly thereafter distributes all or substantially all of such
       consideration to its stockholders, or the Purchaser is required or

       redemption thereof on the Closing Date, and the average price per $1,000
       face amount thereof payable by the Company pursuant to such agreements or
       tenders, and (ii) the total number of shares of Common Stock outstanding

       principal amount of at least $80,500,000, and for an aggregate purchase

       offer directed to the holders of the Senior Subordinated Notes and/or
       individually negotiated arrangements, on terms and conditions reasonably
       satisfactory to the Company in its sole but reasonable discretion, Senior
       Subordinated Notes in an aggregate principal amount of at least
       $80,500,000, for an aggregate purchase price not exceeding (a) $580 per
       $1,000 principal amount of Senior Subordinated Note to be repurchased or
       redeemed, and (b) $53,360,000 in the aggregate. The Company shall accept
       all tenders of Senior Subordinated Notes whose owners are willing to have
       their Senior Subordinated Notes repurchased or redeemed at a price equal

<PAGE>

       principal amount, provided that the maximum aggregate purchase price
       (i.e., $53,360,000) is not exceeded. In no event, however, shall the
       Company use (i) more than $7,360,000 from sources other than the proceeds
       received from the sale of the Shares and the Warrants (either by making
       draws under its senior credit facilities or otherwise), or (ii) funds
       from sources other than the proceeds received from the sale of the Shares
       and the Warrants prior to using at least $46,000,000 of proceeds
       available to the Company from the sale of the Shares and the Warrants, to
       repurchase Senior Subordinated Notes. The closing of such repurchase or
       redemption of the Senior Subordinated Notes shall occur on the Closing
       Date and simultaneously with the Closing.

       1.9    Section 13 of the Purchase Agreement is hereby amended by adding
the following subsection 13.10 thereto:

              13.10  Acknowledgment. The Purchaser hereby acknowledges that the
       Loan and Security Agreement contains provisions which prohibit the
       Company from, among other things, making distributions or declaring or
       paying any dividends on, or purchasing, acquiring or redeeming, or
       otherwise retiring any of its capital stock, and the Purchaser hereby
       agrees that the Agent and the Lenders shall not have any liability for
       tortious interference with contractual relations or for inducement by the
       Company to breach of contract or otherwise.

       1.10   The Purchase Agreement is hereby amended by adding a new Exhibit E

              3.11 Limitation on Payment of Redemption Price. Notwithstanding
       anything to the contrary contained in this Certificate of Designations,
       but subject to the last sentence of this Section 3.11, all amounts

       respect of a redemption of shares of Series A Preferred Stock (including,
       without limitation, pursuant to Section 3.3 or Section 3.4) shall be
       subordinated to the prior payment in full of the Obligations (as defined
       in the Loan and Security Agreement) arising under the Loan and Security
       Agreement or any other Loan Document (as defined in the Loan and Security
       Agreement) and the cancellation or cash collateralization of all Letters
       of Credit (as defined in the Loan and Security Agreement) in accordance
       with the subordination provisions of Annex I hereto. Nothing in this
       Section 3.11, however, shall limit or restrict the rights that the
       holders of Series A Preferred Stock would otherwise be entitled to under
       Section 4.2 hereof but for the provisions of this Section 3.11 and the
       subordination provisions of Annex I hereto, it being understood and
       agreed that such holders shall in any event be entitled to exercise their
       rights under Section 4.2 hereof even if the Corporation is limited or
       restricted by this Section 3.11 and/or the subordination provisions of
       Annex I hereto from redeeming shares of Series A Preferred Stock or
       otherwise making payments to the holders thereof.

                 Preferred Stock and Warrant Purchase Agreement
      By and between Numatics, Incorporated and the Purchaser named therein

Subordination Provisions

          1.   So long as any of the Obligations (as defined in the Loan and
Security Agreement) remain unpaid, the Purchaser shall not, and shall have no
right to, (a) ask, demand, sue for, take or receive, or retain, from the Company
or any other person or entity, by setoff or in any other manner, payment of all
or any part of the amount payable by the Company pursuant to Section 2.6(b) of
the Agreement, (b) ask, demand or receive any security for payment of all or any
part of the amount payable by the Company pursuant to Section 2.6(b) of the
Agreement, (c) amend the subordination provisions of this Exhibit E, or (d)
bring or join with any creditor in bringing any proceeding against the Company
under any bankruptcy, reorganization, readjustment or arrangement of debt,
receivership, liquidation or insolvency or similar law or statute now or
hereafter in effect ("Proceedings").

          2.   Without limiting the foregoing, upon any distribution of the
assets of the Company in connection with any dissolution, winding up,
liquidation or reorganization of the Company (whether in any Proceedings or upon
an assignment for the benefit of creditors or any other marshalling of the
assets and liabilities of the Company or otherwise), (a) until such time as all
Obligations (as defined in the Loan and Security Agreement) have been paid in
full and all Letters of Credit (as defined in the Loan and Security Agreement)
have been cancelled or cash collateralized, the Agent and the Lenders shall
first be entitled to receive payment in full of the Obligations (as defined in
the Loan and Security Agreement) and cash collateral in respect of the Letters
of Credit (as defined in the Loan and Security Agreement) before the Purchaser
shall be entitled to receive payment of any amount payable by the Company
pursuant to Section 2.6(b) of the Agreement. Upon any such dissolution, winding
up, liquidation or reorganization, any payment or distribution of assets of the
Company of any kind or character, whether in cash, property or securities, to
which the Purchaser would be entitled except for the subordination provisions of
this Exhibit E shall be made by the liquidating trustee or agent or other
persons making such payment or distribution (whether a trustee in bankruptcy, a
receiver or liquidating trustee or otherwise) (a "Paying Party"), or if received
by the Purchaser, by the Purchaser, directly to the Agent and the Lenders, until
such time as all Obligations (as defined in the Loan and Security Agreement)
have been paid in full and all Letters of Credit (as defined in the Loan and
Security Agreement) have been cancelled or cash collateralized. The Purchaser
hereby authorizes and directs each Paying Party to pay over to the Agent and the
Lenders, upon demand by the Agent, all such payments or distributions without
the necessity of any inquiry as to the status or balance of the outstanding
Obligations (as defined in the Loan and Security Agreement), and without further
notice to or consent of the Purchaser.

<PAGE>

          3.   In the event any payment or distribution of assets of the Company
of any kind or character, whether in cash, property or securities, and whether
or not pursuant to any dissolution, winding up, liquidation or reorganization,
not permitted by or in accordance with the subordination provisions of this
Exhibit E shall be received by the Purchaser, such payment or distribution to
the Purchaser shall not be commingled with other funds and shall be held in
trust for the benefit of, and shall be paid over or delivered to, the Agent, or
to its representatives, in precisely the form received (except for the
endorsement or assignment of the Purchaser where necessary). Any such payment or
distribution received by the Purchaser and paid to the Agent shall be deemed not
to be a payment in respect of amounts payable by the Company pursuant to Section
2.6(b) and such amounts shall remain payable as if such payment or distribution
had never been made by the Company or received by the Purchaser. In the event of
any failure by the Purchaser to make any such endorsement or assignment, the
Agent is hereby irrevocably authorized to make same.

          4.   The Purchaser shall not be entitled to be subrogated to any of
the rights of the Agent or any Lender against the Company or any other person or
entity nor shall the Purchaser be entitled to any benefit of any lien or other
encumbrance securing any of the Obligations (as defined in the Loan and Security
Agreement) or any collateral subject to any such lien, or to rights of offset
held by the Agent or any Lender for the payment of any of the Obligations (as
defined in the Loan and Security Agreement), nor shall the Purchaser have any
right of indemnity, reimbursement or contribution against the Company or any
other person or entity for any payment of the Obligations (as defined in the
Loan and Security Agreement), and the Purchaser expressly waives each and every
such right of subrogation, indemnity, reimbursement and contribution that it
would have but for the subordination provisions of this Exhibit E until such
time as all Obligations (as defined in the Loan and Security Agreement) have
been paid in full and all Letters of Credit (as defined in the Loan and Security
Agreement) have been cancelled or cash collateralized.

          5.   All references in this Exhibit E to the Obligations (as defined
in the Loan and Security Agreement) are to be understood to include all amounts
due on the Obligations (as defined in the Loan and Security Agreement) both
before and after and filing of any Proceeding by or against the Company, and the
Agent and the Lenders and their successors and assigns as creditors in respect
of the Obligations (as defined in the Loan and Security Agreement) shall be
entitled to amounts accruing on the Obligations (as defined in the Loan and
Security Agreement) from the date of filing of any such Proceeding to the date
of full and final payment of the Obligations (as defined in the Loan and
Security Agreement) and the cancellation or cash collateralization of all
Letters of Credit (as defined in the Loan and Security Agreement). All
Obligations (as defined in the Loan and Security Agreement) to which the
provisions of this Exhibit E may apply shall conclusively be presumed to have
been created in reliance on the subordination provisions of this Exhibit E.

          6.   In the event of a breach by the Purchaser of any of the
subordination provisions of this Exhibit E, each of the Agent and the Lenders
(and their successors and assigns) shall have all rights provided to them under
law or equity, including without limitation the right to sue the Purchaser to
recover damages suffered as a result of such breach, and the right to obtain
injunctive relief.

                                       8

<PAGE>

          7.   Notwithstanding any other provision in this Exhibit E to the
contrary, nothing in this Exhibit E shall limit or restrict the rights that the
holders of the Shares would otherwise be entitled to under Section 4.2 of the
Certificate of Designations but for the provisions of this Exhibit E, it being
understood and agreed that such holders shall in any event be entitled to
exercise their rights under such Section 4.2 hereof even if the Company is
limited or restricted by this Exhibit E from redeeming shares of Series A
Preferred Stock or otherwise making payments to the holders thereof.

Subordination Provisions

          1.   So long as any of the Obligations (as defined in the Loan and
Security Agreement) remain unpaid, the Purchaser shall not, and shall have no
right to, (a) ask, demand, sue for, take or receive, or retain, from the
Corporation or any other person or entity, by setoff or in any other manner,
payment of all or any part of the amount payable by the Corporation pursuant to
Section 2.6(b) of the Agreement, (b) ask, demand or receive any security for
payment of all or any part of the amount payable by the Corporation pursuant to
Section 2.6(b) of the Agreement, (c) amend the subordination provisions of this
Annex I, or (d) bring or join with any creditor in bringing any proceeding
against the Corporation under any bankruptcy, reorganization, readjustment or
arrangement of debt, receivership, liquidation or insolvency or similar law or
statute now or hereafter in effect ("Proceedings").

          2.   Without limiting the foregoing, upon any distribution of the
assets of the Corporation in connection with any dissolution, winding up,
liquidation or reorganization of the Corporation (whether in any Proceedings or
upon an assignment for the benefit of creditors or any other marshalling of the
assets and liabilities of the Corporation or otherwise), (a) until such time as
all Obligations (as defined in the Loan and Security Agreement) have been paid
in full and all Letters of Credit (as defined in the Loan and Security
Agreement) have been cancelled or cash collateralized, the Agent and the Lenders
shall first be entitled to receive payment in full of the Obligations (as
defined in the Loan and Security Agreement) and cash collateral in respect of
the Letters of Credit (as defined in the Loan and Security Agreement) before the
Purchaser shall be entitled to receive payment of any amount payable by the
Corporation pursuant to Section 2.6(b) of the Agreement. Upon any such
dissolution, winding up, liquidation or reorganization, any payment or
distribution of assets of the Corporation of any kind or character, whether in
cash, property or securities, to which the Purchaser would be entitled except
for the subordination provisions of this Annex I shall be made by the
liquidating trustee or agent or other persons making such payment or
distribution (whether a trustee in bankruptcy, a receiver or liquidating trustee
or otherwise) (a "Paying Party"), or if received by the Purchaser, by the
Purchaser, directly to the Agent and the Lenders, until such time as all
Obligations (as defined in the Loan and Security Agreement) have been paid in
full and all Letters of Credit (as defined in the Loan and Security Agreement)
have been cancelled or cash collateralized. The Purchaser hereby authorizes and
directs each Paying Party to pay over to the Agent and the Lenders, upon demand
by the Agent, all such payments or distributions without the necessity of any
inquiry as to the status or balance of the outstanding Obligations (as defined
in the Loan and Security Agreement), and without further notice to or consent of
the Purchaser.

          3.   In the event any payment or distribution of assets of the
Corporation of any kind or character, whether in cash, property or securities,
and whether or not pursuant to any dissolution, winding up, liquidation or
reorganization, not permitted by or in accordance with the subordination
provisions of this Annex I shall be received by the Purchaser, such payment or
distribution to the Purchaser shall not be commingled with other funds and shall
be held in trust for the benefit of, and shall be paid over or delivered to, the
Agent, or to its representatives, in precisely the form received (except for the
endorsement or assignment of the Purchaser where necessary). Any such payment or
distribution received by the Purchaser and paid to the Agent shall be deemed not
to be a payment in respect of amounts payable by the Corporation pursuant to
Section 2.6(b) of the Agreement and such amounts shall remain payable as if such
payment or distribution had never been made by the Corporation or received by
the Purchaser. In the event of any failure by the Purchaser to make any such
endorsement or assignment, the Agent is hereby irrevocably authorized to make
same.

          4.   The Purchaser shall not be entitled to be subrogated to any of
the rights of the Agent or any Lender against the Corporation or any other
person or entity nor shall the Purchaser be entitled to any benefit of any lien
or other encumbrance securing any of the Obligations (as defined in the Loan and
Security Agreement) or any collateral subject to any such lien, or to rights of
offset held by the Agent or any Lender for the payment of any of the Obligations
(as defined in the Loan and Security Agreement), nor shall the Purchaser have
any right of indemnity, reimbursement or contribution against the Corporation or
any other person or entity for any payment of the Obligations (as defined in the
Loan and Security Agreement), and the Purchaser expressly waives each and every
such right of subrogation, indemnity, reimbursement and contribution that it
would have but for the subordination provisions of this Annex I until such time
as all Obligations (as defined in the Loan and Security Agreement) have been
paid in full and all Letters of Credit (as defined in the Loan and Security
Agreement) have been cancelled or cash collateralized.

          5.   All references in this Annex I to the Obligations (as defined in
the Loan and Security Agreement) are to be understood to include all amounts due
on the Obligations (as defined in the Loan and Security Agreement) both before
and after and filing of any Proceeding by or against the Corporation, and the
Agent and the Lenders and their successors and assigns as creditors in respect
of the Obligations (as defined in the Loan and Security Agreement) shall be
entitled to amounts accruing on the Obligations (as defined in the Loan and
Security Agreement) from the date of filing of any such Proceeding to the date
of full and final payment of the Obligations (as defined in the Loan and
Security Agreement) and the cancellation or cash collateralization of all
Letters of Credit (as defined in the Loan and Security Agreement). All
Obligations (as defined in the Loan and Security Agreement) to which the
provisions of this Annex I may apply shall conclusively be presumed to have been
created in reliance on the subordination provisions of this Annex I.

          6.   In the event of a breach by the Purchaser of any of the
subordination provisions of this Annex I, each of the Agent and the Lenders (and
their successors and assigns) shall have all rights provided to them under law
or equity, including without limitation the right to sue the Purchaser to
recover damages suffered as a result of such breach, and the right to obtain
injunctive relief.
