Incorporation was adopted by the shareholders of Mine Safety Appliances Company, predecessor of the Company, at their Annual Meeting held on April&nbsp;24, 1987. Pursuant to its reorganization into a holding company organizational structure in 2014,
the Registrant&#146;s Articles of Incorporation are identical to those of its predecessor. Article 14th provides that, to the fullest extent allowed by the BCL, no director of the Registrant shall be personally liable for monetary damages as such
for any action taken, or any failure to take any action, as a director. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">3. <I>Indemnification Bylaw.</I> Section&nbsp;7.01 of the
Registrant&#146;s Bylaws (the &#147;Indemnification Bylaw&#148;) was adopted by the shareholders of Mine Safety Appliances Company, predecessor of the Company, at their Annual Meeting held on April&nbsp;24, 1987. Pursuant to its reorganization into
a holding company organizational structure in 2014, the Company&#146;s Bylaws are identical to those of its predecessor. Under the Indemnification Bylaw, except as prohibited by law, every director and officer of the Registrant is entitled as of
right to be indemnified by the Registrant against all expenses and liabilities incurred in connection with any actual or threatened claim or proceeding, whether civil, criminal, administrative, investigative or other, whether brought by or in the
right of the Registrant or otherwise, in which the director or officer may be involved in any manner, by reason of his or her being or having been a director or officer of the Registrant or by reason of the fact that he or she is or was serving at
the request of the Registrant as a director, officer, employee, fiduciary or other representative of another corporation or other entity. In an action brought by a director or officer against the Registrant, the director or officer is only entitled
to indemnification for expenses in certain circumstances. Each director and officer is also entitled as of right to have his or her expenses in defending an action paid in advance by the Registrant prior to final disposition of the action, subject
to any obligation which may be imposed to reimburse the Registrant in certain events. The Indemnification Bylaw establishes a procedure whereby a director or officer may bring an action against the Registrant if a written claim for indemnification
or advancement of expenses is not paid by the Registrant in full within thirty days after the claim has been presented. The director or officer is also entitled to advancement of expenses in this proceeding. The only defense to an action to recover
a claim for indemnification is that the indemnitee&#146;s conduct was such that under Pennsylvania law the Registrant is prohibited from indemnifying the indemnitee. The only defense to an action to recover payment of expenses in advance is failure
by the indemnitee to make an undertaking to reimburse the Registrant if such an undertaking is required. In addition, Section&nbsp;7.02 of the Registrant&#146;s Bylaws, like Article 14th of the Registrant&#146;s Articles of Incorporation, provides
that, to the fullest extent allowed by the BCL, no director of the Registrant shall be personally liable for monetary damages as such for any action taken, or any failure to take any action, as a director. </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">Any amendment or repeal of the Indemnification Bylaw will operate prospectively only and will not affect any action taken, or failure to act,
by a director or officer prior to the adoption of such amendment or repeal. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">4. <I>Director and Officer Liability Insurance.</I> The
Registrant maintains director and officer liability insurance covering its directors and officers with respect to liability which they may incur in connection with their serving as such, which liability could include liability under the Securities
Act of 1933. Under the insurance, the Registrant is entitled to reimbursement for amounts as to which the directors and officers are indemnified under the Indemnification Bylaw. The insurance may also provide certain additional coverage for the
directors and officers against certain liability even though such liability is not subject to indemnification under the Indemnification Bylaw. </P>

liabilities and expenses as are provided in the Indemnification Bylaw. In addition, the form of agreement requires the Registrant to either maintain the liability insurance coverage currently in effect for the benefit of the contractee or to hold
the contractee harmless to the full extent of such coverage. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">Further, the form of agreement provides that if the full indemnification
claimed by the contractee may not be paid by the Registrant because prohibited by law and the Registrant is jointly liable with the contractee as to the matter for which indemnification was sought (or would be so liable if the Registrant were joined
in such matter), the contractee has a right to contribution from the Registrant for the amount of any expenses and liabilities incurred by the contractee as to such matter based on the relative benefits received by the Registrant and the contractee
from the transaction from which the liability arose and the relative fault of the Registrant (including the Registrant&#146;s other directors, officers, employees or agents) and the contractee in connection with the events which resulted in such
expenses or liability, as well as any other relevant equitable considerations. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">Under the form of agreement, a contractee is entitled to
the rights to indemnification for expenses and liability, advancement of expenses and contribution provided by the agreement notwithstanding any amendment or repeal of the Indemnification Bylaw. In addition, although a change in law restricting
indemnification rights would automatically restrict the indemnification rights provided under the Indemnification Bylaw, the form of agreement provides that a change in law restricting indemnification rights will not affect the rights of a
contractee under the agreement unless the law so requires. </P> <P STYLE="margin-top:18pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman"><B>Item&nbsp;7. Exemption From Registration Claimed. </B></P>
