Exhibit 10.58  AMENDMENT
TO EMPLOYMENT AGREEMENT (For
Compliance with Requirements of Code Section 409A)  This Amendment to
Employment Agreement between Magellan Health Services, Inc. (Employer)
and Daniel Gregoire (Employee) entered into as of this 1st day of December, 2008.  WHEREAS,
Employer and Employee desire to amend the terms of the Employment Agreement, as
amended, currently in effect between Employer and Employee (the Employment
Agreement).  NOW THEREFORE,
Employer or Employee agree that the Employment Agreement is hereby amended as
follows:  1.Reorganization of Sections of Employment Agreement.  Section 10 of the Employment Agreement (Governing
Law) is moved to become the fifth to last Section of the Employment
Agreement, and renumbered accordingly, with the four final Sections renumbered
appropriately.  2.New Section of Employment Agreement.  The following new text is inserted as Section 10
of the Employment Agreement:  10Special Rules for Compliance
with Code Section 409A.  This Section 10
serves to ensure compliance with applicable requirements of Section 409A
of the Internal Revenue Code (the Code). 
Certain provisions of this Section 10 modify other provisions of this
Employment Agreement.  If the terms of
this Section 10 conflict with other terms of the Employment Agreement, the
terms of this Section 10 control.  (a)Timing of Certain Payments. 
Payments and benefits specified under this Employment Agreement shall be
paid at the times specified as follows:  (i)Accrued
Payments at Termination.  Sections 6(a)  (d) of this
Employment Agreement and Section I.1(ii) of the Amendment to the
Employment Agreement relating to Change in Control ( the CiC Amendment) require
payment of amounts earned but unpaid, or accrued, at the date of Employees
termination.  Unless the amount is
payable under an applicable plan, program or arrangement on explicit terms
providing for a delay in payment compliant with Code Section 409A, these
amounts shall be payable at the date the amounts otherwise would have been
payable under the applicable plans, programs and arrangements in the absence of
termination but in no event more than thirty (30) days after Employees
termination of employment, subject to 10(d).


(ii)Gross-Up. 
Gross-up payments payable under the CiC Amendment will be paid as
promptly as practicable after the excise tax is payable by Employee, and in any
event must be paid no later than the end of Employees taxable year next
following the taxable year in which Employee remits the excise tax or related
taxes to the taxing authorities; provided, however, that any gross-up payment
will be subject to Section 10(d) if applicable under Section 409A.  (iii)Expense
Reimbursements.  Any payment under Section 5 or otherwise
as an expense reimbursement hereunder must be paid no later than the end of
Employees taxable year next following the taxable year in which Employee
incurred the reimbursable expense.  (iv)Other
Payments.  Any other payment or benefit required under this
Employment Agreement to be paid in a lump sum or otherwise to be paid promptly
at or following a date or event shall be paid within five (5) days after
the due date, subject to Section 10(b), (c) and (d) below.  (v)No
Influence on Year of Payment.  In the case of any payment under the
Employment Agreement payable during a specified period of time following a
termination or other event (including any payment for which the permitted
payment period begins in one calendar year and ends in a subsequent calendar
year), Employee shall have no right to elect in which year the payment will be
made, and the Companys determination of when to make the payment shall not be
influenced in any way by Employee.  (b)Special Rules for Severance Payments.  In
the case of payments of severance required under Section 6(c)(iii) (Pre-CiC
Severance Payment) and severance payable under Section I.1(iii) of the
CiC Amendment (the CiC Severance Payments and, with the Pre-CiC Severance
Payment, the Severance Payments), the following rules will apply:  (i)Separate
Payments.  The Pre-CiC Severance Payment shall be deemed
to be a separate payment for all purposes, including for purposes of Section 409A.  The portion of the CiC Severance Payments
that exceeds the Pre-CiC Severance Payment (or the present value thereof, if
such present valuing is required to comply with Section 409A), and the portion
attributable to inclusion of Target Bonus in the calculation of CiC Severance
Payments (or, if so required, the present value thereof) as compared to Pre-CiC
Severance Payment, shall be deemed to be a separate payment for all purposes,
including for purposes of Section 409A (the Separate Lump Sum).  (ii)Severance
Payment Timing Rules.  The Pre-CiC Severance Payment shall be
treated as follows for purposes of Section 409A:  (A)The Pre
CiC Severance Payment shall, to the maximum extent possible, be deemed to
constitute a short-term deferral under Treasury Regulation §  2


1.409A-1(b)(4);  (B)The
Pre-CiC Severance Payment, to the extent not covered by Section 10(b)(ii)(A),
shall, to the maximum extent possible, be deemed to constitute amounts payable
under the two-year/two-times exclusion from being a deferral of compensation
under Treasury Regulation § 1.409A-1(b)(9)(iii);  (C)[Reserved];
and  (D)To the
extent that the Pre-CiC Severance Payment is not covered by Section 10(b)(ii)(A) an
(B), it shall be paid at the applicable payment date in compliance with Section 409A,
except that any such payment shall be subject to the six-month delay rule of
Section 10(d).  The
portions of the CiC Severance Payments that correspond to the Pre-CiC Severance
Payment (that is, deemed to be the same payment for purposes of Section 409A)
shall be governed by Section 10(b)(ii)(A)  (D) above, provided
that amounts of the CiC Severance Payments corresponding to Pre-CiC Severance
Payment covered by Section 10(b)(ii)(A) and (B) above shall be
payable as a lump sum within five (5) days after termination of
employment.  The Separate Lump Sum shall
be treated as follows for purposes of Section 409A:  (E)The
Separate Lump Sum shall, to the maximum extent possible, be deemed to
constitute a short-term deferral under Treasury Regulation § 1.409A-1(b)(4);  (F)To the
extent that the two-year/two-times exclusion from being a deferral of
compensation under Treasury Regulation § 1.409A-1(b)(9)(iii) has not been
fully applied by virtue of Section 10(b)(ii)(B), the Separate Lump Sum, to
the extent not covered by Section 10(b)(ii)(E), shall, to the maximum
extent possible, be deemed to constitute amounts payable under the two-year/two-times
exclusion; and  (G)Any
portion of the Separate Lump Sum not covered by Section 10(b)(ii)(E) and
(F) shall be paid within five (5) days after the qualifying
termination of employment in compliance with Section 409A, except that any
such payment shall be subject to the six-month delay rule and other
provisions of Section 10(d).  Any
portions of the CiC Severance Payments corresponding to Pre-CiC Severance Payment
governed by Section 10(b)(ii)(D) shall be payable, subject to Section 10(d),
in a lump sum within five (5) days after the qualifying termination of
employment if such termination has occurred within two years following a change
in the ownership of the Company, a change in effective control of the Company,
or a change in the ownership of a substantial portion of the assets of the
Company as defined in Treasury Regulation § 1.409A-3(i)(10) (a 409A
Change in Control), and in any other case shall be payable at the applicable
time under Section 10(b)(ii)(D).  3


(c)Special Rules for Other Payments.  With
respect to amounts payable under Section 6(c)(ii) and/or under Section I.1(ii) of
the CiC Amendment (relating to incentive awards), the following rules will
apply:  (i)Separate
Payments.  The amounts payable thereunder shall each be
deemed to be a separate payment for all purposes, including for purposes of Section 409A
(subject to any further designation of separate payments explicitly made in any
separately identifiable plan or arrangement for purposes of Section 409A).  (ii)Payment
Timing Rules.  A payment referenced in Section 10(c)(i) shall
be payable as a lump-sum payment within five (5) days after termination of
employment if and to the extent that (A) the separate payment constitutes
short-term deferral under Treasury Regulation § 1.409A-1(b)(4), (B) the
amount of the separate payment not covered by Section 10(c)(ii)(A) can
be paid under the two-year/two-times exclusion from being a deferral of
compensation under Treasury Regulation § 1.409A-1(b)(9)(iii), after first
applying such exclusion under Section 10(b)(ii), (C) the separate
payment is covered by any other applicable exclusion or exemption under
Treasury Regulation § 1.409A-1(b)(9) (provided that the exclusion under
subsection (b)(9)(v)(D) shall be used only to the extent not relied upon
for other payments or benefits) and (D), the six-month delay rule in Section 10(d) does
not apply to the separate payment (except as otherwise provided in Section 10(c)(iii)).  Any other such separate payment (i.e.,
amounts subject to the six-month delay rule) shall be subject to the six-month
delay rule of Section 10(d), subject to Section 10(c)(iii).  Any delay in payment under the six-month
delay rule shall not limit Employees rights under this Employment
Agreement to not forfeit a specified item of compensation as a result of
Employees termination.  (iii)Payments
of 409A Deferrals For a Termination Not Within Two Years After a 409A Change in
Control.  If a payment referenced in Section 10(c)(ii) is
a direct payment or a substitute or replacement for a right to payment (the Original
Payment Right) that constitutes a deferral of compensation under Section 409A,
and if either (A) the Change in Control does not involve a 409A Change in
Control, or (B) Employees termination triggering payments hereunder did
not occur within the two-year period following a 409A Change in Control, then
such payments (i.e., payments that constitute deferrals under Section 409A)
must be paid at the times and in the form applicable to a separation from
service under the terms of the Original Payment Right, subject to Section 10(d).  If in no circumstances was such payment
payable upon a separation from service under the Original Payment Right, then
this Section 10(c)(iii) shall not apply.  4


(d)Six-Month Delay Rule.  (i)General
Rule.  The six-month delay rule will apply to
payments and benefits under the Employment Agreement if all of the following
conditions are met:  (A)  Employee is a key employee (as
defined in Code Section 416(i) without regard to paragraph (10) thereof)
for the year in which the termination occurs. 
The Company will determine status of key employees annually, under
administrative procedures applicable to all Section 409A plans and
arrangements and applied in accordance with Treasury Regulation
§ 1.409A-1(i).  (B)  The Companys stock is publicly
traded on an established securities market or otherwise.  (C)  The payment or benefit in question is
a deferral of compensation and not excepted, exempted or excluded from being
such by the short-term deferral rule, or the two-years/two-times rule in
Treasury Regulation § 1.409A-1(b)(9)(iii), or any other exception,
exemption or exclusion; provided, however, that the exclusion under Treasury
Regulation § 1.409A-1(b)(9)(v)(D) shall apply only if and to the
extent that it is not necessary to apply to any other payment or benefit
payable within six (6) months after Employees termination.  (ii)Effect
of Rule.  If it applies, the six-month delay rule will
delay a payment or benefit which otherwise would be payable under this
Employment Agreement within six (6) months after Employees separation
from service.  (A)  Any delayed payment or benefit shall
be paid on the date six (6) months after Employees separation from
service.  (B)  During the six-month delay period,
accelerated payment will occur in the event of the Employees death but not for
any other reason (including no acceleration upon a Change in Control), except
for accelerations expressly permitted under Treasury Regulation § 1.409A-1 
A-6.  (C)  Any payment that is not triggered by
a termination, or is triggered by a termination but would be made more than six
(6) months after the termination (without applying this six-month delay
rule), or would be payable at a fixed date not tied to termination that is
earlier than the expiration of the six-month delay period, shall be unaffected
by the six-month delay rule.  (iii)Limit
to Application of Six-Month Delay Rule.  If the terms of this
Employment Agreement or other plan or arrangement or document relating to this
Employment Agreement or payments hereunder impose this six-month  5


delay
rule in circumstances in which it is not required for compliance with Section 409A,
those terms shall not be given effect.  (e)Other Provisions.  (i)  Good Reason.  The definition of Good Reason under the
Employment Agreement, and related rules governing constructive termination
not for cause, is intended to qualify as an involuntary separation within the
meaning of Treasury Regulation § 1.409A-1(n)(2)(i), and shall be so construed and
interpreted.  (ii)  Non-transferability.  No right to any payment or benefit under this
Employment Agreement shall be subject to anticipation, alienation, sale,
transfer, assignment, pledge, encumbrance, attachment, or garnishment by
Employees creditors or of any of Employees beneficiaries.  (iii)  No Acceleration.  The timing of payments and benefits under the
Employment Agreement which constitute a deferral of compensation under Code Section 409A
may not be accelerated to occur before the time specified for payment
hereunder, except to the extent permitted under Treasury Regulation
§ 1.409A-3(j)(4) or as otherwise permitted under Code Section 409A
without Employee incurring a tax penalty.  (iv)  Timing Relating to Release.  Other provisions of this Employment Agreement
(including this Section 10) notwithstanding, if Employee is obligated to
execute a release, non-competition, or other agreement as a condition to
receipt of a payment hereunder, the Company will supply to Employee a form of
such release or other document not later than the date of Employees
termination, which must be returned within the time period required by law and
must not be revoked by Employee within the applicable time period in order for
Employee to satisfy any such condition, such that it becomes legally effective.  If any amount payable during a fixed period
following Employees termination is subject to a requirement or condition
requiring Employees execution of a release (including any case in which such fixed
period would begin in one year and end in the next), the Company, in
determining the time of payment of any such amount, will not be influenced by Employee
or the timing of any action by Employee including execution of such a release
or other document and expiration of any revocation period.  In particular, the Company will be entitled
in its discretion to deposit any payment hereunder in escrow at any time during
such fixed period, so that such deposited amount is constructively received and
taxable income to Employee upon deposit (it may be constructively received even
in the absence of such deposit) but with distribution from such escrow
remaining subject to Employees execution and non-revocation of such release or
other document.  6


(v)  Definition of Termination of
Employment.  For purposes of this
Employment Agreement, the term termination of employment shall mean a
separation from service as defined in Treasury Regulation § 1.409A-1(h);
provided, however, that if a date for termination of employment is designated
by the Company but Employee has a separation from service prior to such
designated date, the designated termination date shall be deemed the date of
termination for any compensation payable under this Agreement that would fully qualify
for the short-term deferral exception under Treasury Regulation § 1.409A-1(b)(4) and/or
the two-year/two-times exclusion from being a deferral of compensation under
Treasury Regulation § 1.409A-1(b)(9)(iii) under both circumstances (i.e.,
assuming the separation from service date was the termination date hereunder or
that the designated termination of employment date was the termination date
hereunder), then for that purpose the termination of employment date shall be
the designated termination date.  (vi)  References to Other Plans.  References in the Employment Agreement to the
obligation of the Company to pay amounts under other plans, including Employees
vested portion of any Magellan deferred compensation or other benefit plan,
shall not be construed to modify the timing of payment, which shall be governed
by such other plans.  3.Modification to Good Reason Definitions.  The provisions of Section 6(c) setting
forth the definition of Good Reason are hereby amended as follows:  ·In
clause (i), the term reduction is replaced by the term material reduction,
and at the end of clause (i) before the semicolon the following text is
inserted:  provided, however, that a
reduction in Base Salary and/or Target Bonus with an annualized value of one
and one half percent (1.5%) of Employees then current annual base pay or more
in the aggregate, taking into account any related effect a salary reduction has
on target bonus and other components of compensation, shall be deemed material;  ·The
final proviso of Section 6(c) is deleted and in its stead is inserted
the following:  provided that, in each such case, Employee shall have
given notice to the Company that such event or condition has arisen within
ninety (90) days after such event or condition has arisen, and the event or
condition has continued uncured for a period of more than thirty (30) days
after Employee has given such notice thereof to the Company, and Employee has
terminated employment for Good Reason within eighteen (18) months after such
uncured event or condition has arisen.  7


The provisions of Section I.2(C) of
the CiC Amendment setting forth the definition of Good Reason are hereby
amended as follows:  ·In
clause (i), the term reduction in Employees salary is replaced by the term material
reduction in Employees salary, and the term reduction in Employees target
bonus opportunity is replaced by the term material reduction in Employees
target bonus opportunity, and at the end of clause (i) before the
semicolon the following text is inserted:  provided, however, that a
reduction in salary and/or target bonus opportunity with an annualized value of
one and one half percent (1.5%) of Employees then current annual base pay or
more in the aggregate, taking into account any related effect a salary
reduction has on target bonus and other components of compensation, shall be
deemed material;  ·The
final proviso of Section I.2(C) of the CiC Amendment is deleted and
in its stead is inserted the following:  provided that, in each such case, Employee shall have
given notice to the Company that such event or condition has arisen within
ninety (90) days after such event or condition has arisen, and the event or
condition has continued uncured for a period of more than thirty (30) days
after Employee has given such notice thereof to the Company, and Employee has
terminated employment for Good Reason within eighteen (18) months after such
uncured event or condition has arisen.  4.Other Amendments. 
Other provisions of the Employment Agreement are amended as follows:  ·A
new sentence is added as the second to last sentence of Section 1,
stating:  Non-renewal of this
Agreement by either party will in all cases result in termination of employment
at the non-renewal date.  ·A
new sentence is added at the end of Section 4(b), stating:  Annual bonus, if any,
will be determined and paid (unless validly deferred if then permitted by the
Company) between January 1 and March 15 of the year following the
performance year.  ·A
clause is inserted before the period at the end of Section 5, stating:  subject to Section 10(a)(iii).  ·In
the preamble to Section I.1 of the CiC Amendment, before the colon insert ,
in each case subject to Section 10.  8


·A
new sentence is added at the end of Section 4(c), as follows:  Any continued medical
coverage following termination of employment, to the extent provided under Section 6
or any other provision of this Agreement, if and to the extent such medical
coverage (or the Companys contributions or reimbursement of such coverage)
represents taxable income to Employee, is intended to qualify as excluded from
being a deferral of compensation under Treasury Regulation §
1.409A-1(b)(9)(v)(B), and the rights to such coverage shall be limited to the
extent necessary to qualify thereunder.  5.Nothing
in this Amendment shall be construed to increase or enhance the compensation or
benefits payable under the Agreement. 
The sole purpose of this Amendment is to add limitations required under
Code Section 409A so that payments and benefits otherwise provided under
the Agreement are not subject to tax penalties and other adverse consequences
under Section 409A.  This amendment to
Employment Agreement is entered into by the parties as of the date first above
written.   Magellan Health
