child to less than 48 hours following vaginal delivery, or less than 96 hours

authority for adjudicating all claims and a full review of the decision on such
claims in accordance with the following provisions and with the Employee
Retirement Income Security Act of 1974, as amended (&#147;ERISA&#148;).&#160; The Plan Administrator has delegated the

the Plan Administrator in its sole discretion may require, written proof that
the expenses were incurred or that the benefit is covered under the Plan.&#160; If the Plan Administrator in its sole

<p style="margin:0in 0in .0001pt .5in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">A &#147;Pre-service Claim&#148; is a claim for a
benefit under the Plan where the Plan conditions receipt of the benefit, in
whole or in part, on approval of the benefit in advance of obtaining medical
care.</font></p>

<p style="margin:0in 0in .0001pt;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">&nbsp;</font></p>

<p style="margin:0in 0in .0001pt .5in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">A &#147;Pre-service Urgent Care Claim&#148; is any
claim for medical care or treatment with respect to which the application of
the time periods for making non-urgent care determinations could seriously
jeopardize the life or health of the claimant or the claimant&#146;s ability to
regain maximum function, or, in the opinion of a physician with knowledge of
the claimant&#146;s medical condition, would subject the claimant to severe pain
that cannot be adequately managed without the care or treatment that is the
subject of the claim.</font></p>

<p style="margin:0in 0in .0001pt;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">&nbsp;</font></p>

<p style="margin:0in 0in .0001pt .5in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">It is important to remember that, if a
claimant needs medical care for a condition which could seriously jeopardize
his life, there is no need to contact the Plan for prior approval. The claimant
should obtain such care without delay.</font></p>

<p style="margin:0in 0in .0001pt .5in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">&nbsp;</font></p>

<p style="margin:0in 0in .0001pt .5in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">Further, if the Plan does not <u>require</u>
the claimant to obtain approval of a medical service <u>prior</u> to getting
treatment, then there is no &#147;Pre-service Claim.&#148;&#160; The claimant simply follows the Plan&#146;s procedures with respect to
any notice which may be required after receipt of treatment, and files the
claim as a Post-service Claim.</font></p>

<p style="margin:0in 0in .0001pt .5in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">A &#147;Concurrent Claim&#148; arises when the Plan has
approved an on-going course of treatment to be provided over a period of time
or number of treatments, and either (a) the Plan determines that the course of
treatment should be reduced or terminated, or (b) the claimant requests
extension of the course of treatment beyond that which the Plan has approved.</font></p>

<p style="margin:0in 0in .0001pt .5in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">&nbsp;</font></p>

state plan of medical assistance approved under Title XIX of the Social
Security Act pursuant to Section 1912(a)(1)(A) of such Act (as in effect on the
date of enactment of the Omnibus Budget Reconciliation Act of 1993). In
enrolling a Participant or in determining or making any payments for benefits
for benefits to or on behalf of the Participant, the fact that such Participant
is eligible for or is provided medical assistance under a state plan for
medical assistance under Title XIX of the Social Security Act will not be taken

made under a state plan for medical assistance approved under Title XIX of the
Social Security Act in any case in which the Plan, after applying the Plan&#146;s

make payments for items or services constituting such assistance, payment for
benefits under the Plan will be made in accordance with any state law which
provides that the state has acquired the rights of the Participant to such
