distributable to such Claimant from the Plan. If such a claim relates to the contents of a notice received by the Claimant, the claim must be made within 60 days after such notice was received by the Claimant. All other claims must be made within
180 days of the date on which the event that caused the claim to arise occurred. The claim must state with particularity the determination desired by the Claimant.

8.2 Notification of Decision. The Designee shall consider a Claimants claim within a reasonable time, but no later than 90 days after receiving the claim. If the Designee determines that
special circumstances require an extension of time for processing the claim, written notice of the extension shall be furnished to the Claimant prior to the termination of the initial 90-day period. In no event shall such extension exceed a period
of 90 days from the end of the initial period. The extension notice shall indicate the special circumstances requiring an extension of time and the date by which the Designee expects to render the benefit determination. The Designee shall notify the
Claimant in writing:

(a) that the Claimants requested determination has been made, and that the claim has been allowed
in full; or

(b) that the Designee has reached a conclusion contrary, in whole or in part, to the Claimants requested
determination, and such notice must set forth in a manner calculated to be understood by the Claimant:

(i) the specific
reason(s) for the denial of the claim, or any part of it;

(ii) specific reference(s) to pertinent provisions of the Plan
upon which such denial was based;

(iii) a description of any additional material or information necessary for the Claimant
to perfect the claim, and an explanation of why such material or information is necessary;

(iv) an explanation of the claim
review procedure set forth in Section 8.3 below; and

---

(v) a statement of the Claimants right to bring a civil action under ERISA
Section 502(a) following an adverse benefit determination on review.

8.3 Review of a Denied Claim. On or before
60 days after receiving a notice from the Designee that a claim has been denied, in whole or in part, a Claimant (or the Claimants duly authorized representative) may file with the Designee a written request for a review of the denial of the
claim. The Claimant (or the Claimants duly authorized representative):

(a) may, upon request and free of charge, have
reasonable access to, and copies of, all documents, records and other information relevant (as defined in applicable ERISA regulations) to the claim for benefits;

(b) may submit written comments or other documents; and/or

(c) may request a
hearing, which the Designee, in its sole discretion, may grant.

8.4 Decision on Review. The Designee shall render its
decision on review promptly, and no later than 60 days after the Designee receives the Claimants written request for a review of the denial of the claim. If the Designee determines that special circumstances require an extension of time for
processing the claim, written notice of the extension shall be furnished to the Claimant prior to the termination of the initial 60-day period. In no event shall such extension exceed a period of 60 days from the end of the initial period. The
extension notice shall indicate the special circumstances requiring an extension of time and the date by which the Designee expects to render the benefit determination. In rendering its decision, the Designee shall take into account all comments,
documents, records and other information submitted by the Claimant relating to the claim, without regard to whether such information was submitted or considered in the initial benefit determination. The decision must be written in a manner
calculated to be understood by the Claimant, and it must contain:

(a) specific reasons for the decision;

(b) specific reference(s) to the pertinent Plan provisions upon which the decision was based;

(c) a statement that the Claimant is entitled to receive, upon request and free of charge, reasonable access to and copies of, all
documents, records and other information relevant (as defined in applicable ERISA regulations) to the Claimants claim for benefits; and

(d) a statement of the Claimants right to bring a civil action under ERISA Section 502(a).

8.5 Disability Benefits. The Designee shall comply with the special rules for Disability claims in 29 CFR §2560.503-1, where the availability of the benefit is conditioned upon a showing of
Disability. Where a benefit is available only on a finding of Disability and such finding has already been determined under another benefit plan or program of the Employer, the special Disability claim rules need not apply and the rules of this
Section 8 shall govern.

8.6 Action by Authorized Representative of Claimant. All actions set forth in this
Section 8 to be taken by the claimant likewise may be taken by a representative of the claimant duly authorized by him to act on his behalf on such matters. The Designee and the Committee may require such evidence of the representatives
authority to act as either the Designee or the Committee may reasonably deem necessary or advisable.

8.7. Legal
Action. A Claimants compliance with the foregoing provisions of this Section 8 is a mandatory prerequisite to a Claimants right to commence any legal action with respect to any claim for benefits under this Plan.

IX. MISCELLANEOUS

9.0 Competence: Every person receiving or claiming amounts payable under this Plan shall be conclusively presumed mentally competent and of legal age until the Committee receives a written notice, in a form, manner and substance
acceptable to it, that the person is incompetent or is a minor or that a guardian or other person usually vested with care of the persons estate has been appointed. In that case, payments shall be made to the appointed person on behalf of the
recipient. Payment to such person or institution shall be in full satisfaction of all claims by or through the Participant to the extent of the amount thereof.

9.1 Lost Distributees: Notwithstanding any contrary provision herein, a benefit shall be deemed forfeited if the Committee is unable after a reasonable effort to locate the Participant or any party
claiming under or through him to whom payment is due; provided, however, that such benefit shall be reinstated if a valid claim is made by or on behalf of such person for the forfeited benefit.

9.2 Receipt and Release for Payments: Any payment made from the Plan to or with respect to any Participant shall be in full
satisfaction of all claims hereunder against the Plan and Sterling with respect to the Plan to the extent of such payment. The recipient of any payment from the Plan may be required by the Committee to execute a receipt and release thereto in such
form as shall be acceptable to the Committee as a condition precedent to such payment.

9.3 Employment Not Guaranteed:
Nothing contained in the Plan nor any action taken hereunder shall be construed as a contract of employment or as giving any Participant any right to be retained in the employ of Sterling, nor shall it interfere with the right of Sterling to
discharge a Participant or deal with him without regard to the effect thereof under the Plan.

9.4 No Liability:
Neither Sterling, the Committee, the Board nor any affiliate of any of them shall be liable for any action or determination made with respect to this Plan.

9.5 No Guarantee of Tax Consequences: Neither Sterling nor the Committee makes any commitment or guarantee that any federal or state tax treatment will apply or be available to any Participant in
the Plan.

9.6 Merger: This Plan document including Exhibits constitute the full and entire understanding with regard
to this subject matter and may not be modified or abrogated orally or by course of dealing, but only by another instrument in writing duly adopted by the Board.

9.7 Severability: In the event any provision of this Plan shall be held illegal,
invalid or unenforceable for any reason, such provision shall be fully severable, but shall not affect the remaining provisions of the Plan, and the Plan shall be construed and enforced as if the illegal, invalid or unenforceable provision had never
been included herein.

9.8 Benefits Not Assignable: Neither the Participant nor Beneficiary may assign, transfer,
anticipate or pledge the benefits under this Plan, nor may they be subject to attachment or garnishment of creditors. Any attempt to assign, transfer or pledge a Participants benefits under this Plan is void.

9.9 Headings: The headings and subheadings of the Plan have been inserted for convenience of reference and are to be ignored in any
construction of the provisions hereof.

9.10 Notice: Any notices required or permitted to be given under this Plan
