Subject: Separation & Retirement Transition Parameters

Per our discussions below are the terms for your transition to retirement. If
you are in agreement, please sign where indicated on page two, retain a copy for
your records, and return the original to me. If you have additional questions,
please call me.

Effective Date

You will remain in your current role as Executive Vice President, Global Supply
Chain, Engineering & Systems at your current compensation through January 31,
2000. Effective February 1, 2000 you will assume the title Executive Director,
Special Projects and will continue to report to Mark Bulriss. Your base salary
will continue at the current rate through December 31, 2000 or until you choose
to retire, whichever occurs first, and you will not be required to come into the
office unless requested to do so by Mark Bulriss or his designee.

MICP

Any earned 1999 Incentive Compensation Plan award will be paid in calendar year
2000, and will be considered in the calculation of your earned pension benefit
under the terms outlined in the Plan. Participation in the 2000 IC Plan will be
prorated based on total project hours completed during 2000. All bonus payments
shall be treated consistent with the terms and definitions prescribed by the
Pension Plan.

Change in Control Agreement

Your existing Change in Control agreement will remain valid through the earlier
of 12/31/00 or the effective date of your retirement.

Stock Options

All stock options previously granted to you will continue to vest until the
effective date of your retirement. Stock options granted in 1999 can be
exercised at any time after vesting occurs, and must be exercised within three
(3) years from the effective date of your retirement. Options granted in any
year prior to 1999 can be exercised at any time after vesting occurs, and must
be exercised by the earlier of: one (1) year from the effective date of your
retirement if the market price exceeds the exercise price of any such option as
of the effective date of your retirement; three (3) years from the effective
date of your retirement if the exercise price exceeds the market price of any
such option on the effective date of your retirement; or ten (10) years from the
date the options were granted. You will not be eligible for stock option grants
after December 31st, 1999.

Employee Benefits

As an active employee you will be eligible to participate in the Company's
retirement, health and welfare plans until December 31, 2000 or until the
effective date of your retirement, whichever

                                                                 L.D. Simpson, 2

occurs first. Should changes be made to these plans while you are still an
active employee, you will participate in the changes on the same basis as other
employees.

Life Insurance

The existing Split Dollar life insurance policy in your name will remain in
effect until your death under the terms of the Split Dollar Agreement in effect
between you and Great Lakes Chemical.

Pension

Pension benefits will be calculated in accordance with the applicable Great
Lakes Pension and Supplemental Executive Retirement Plan (SERP). A pension
calculation consistent with the terms of these plans will be provided
separately.

Miscellaneous

Effective with your retirement, the Company will transfer title to the company
car assigned to you to your name, and forgive any debt owed on this vehicle by
you, if any. Ownership of the computer currently assigned to you will be
transferred to you as well. In addition, the Company will reimburse you (to a
maximum of $15,000) for expenses associated with the sale of your home and/or
the storage/movement of your household goods, provided such a move occurs before
December 31, 2001. Any vacation carry-over due you will be paid with your last
pay of January 2000.

As additional consideration for the benefits and payments to be received by you
pursuant to this agreement, you agree that:

For the period beginning with your retirement date and ending one (1) year after
such date (the "Restrictive Period"), you will not, without the consent of the
President & CEO of Great Lakes Chemical, directly or indirectly, compete with
the business of Great Lakes. This restriction shall include but not be limited
to your directly or indirectly serving as an employee of or consultant to, or by
soliciting or inducing, or attempting to solicit or induce, any employee of
Great Lakes to terminate employment with Great Lakes and become employed by, any
person, firm, partnership, corporation, trust or other entity which directly
competes with Great Lakes. With respect to a directorship, such consent will not
be unreasonably withheld so long as you continue to abide by your
confidentiality and proprietary information obligations to Great Lakes Chemical.

You waive any claims against and release Great Lakes Chemical and any
subsidiary, parent or otherwise related company, and their officers, employees
and agents from all claims or causes of action which you may have against them
arising out of the circumstances leading to the negotiation and execution of
this Agreement. This waiver and release shall include, but is not limited to,
any claims or causes of action which you may have for relief under any law,
statute, rule regulation or enactment dealing with employment discrimination, as
well as all claims or causes of action for wrongful discharge, tort, or breach
of contract arising under the statutory or common law of the United States or
any state or political subdivision thereof. You acknowledge that this waiver and
release is an essential and material term of this Agreement and that, without
such a provision, the parties would have reached no agreement.

Nothing in the preceding paragraph shall waive or release the obligations of
Great Lakes Chemical under this Agreement. Nothing in this Agreement shall
affect your rights to indemnification under the Certificate of Incorporation or
By-Laws of Great Lakes Chemical as in effect on or before your retirement date
with respect to your actions or omissions as an officer or employee of Great
Lakes. Great Lakes will continue to cover you under its directors' and officers'
liability policies for as long as and to the extent that it provides such
coverage to former officers of the company. Nothing in this Agreement waives
your rights under any pension or other employee benefit plan, except as
expressly set forth in this Agreement.

                         AGREEMENT AND GENERAL RELEASE

                  The parties to this Agreement and General Release, (the
"Agreement"), entered into this 28th day of January, 2000, are Paul J. Griswold
("Employee" or "Griswold"), on one hand and Pactiv Corporation, a Delaware
corporation ("Employer" or "Pactiv") on the other, sometimes referred to
collectively as the "parties."

                  In consideration of the promises, mutual covenants and
agreements contained in this Agreement, Employee and Employer agree as follows:

                  1. Employee acknowledges that he voluntarily approached
Employer and offered to resign from any and all offices and positions he holds
with Employer, its direct or indirect subsidiaries, affiliates and related
companies or entities, regardless of its or their form of business organization,
including without limitation the plans described in Section 2 (the "Employer
Entities" or "Pactiv Entities"). Employee further acknowledges that he was
neither forced nor encouraged to resign and that he approached Employer solely
on his own rather than as part of any group or group termination program.
Employee understands that, as a result of his decision to resign voluntarily, he
is not entitled to severance under any written severance policy of Employer.
However, the parties have determined to make an exception in Employee's case and
to offer him a severance package.

                  2. Effective February 29, 2000 (the "Termination Date"),
Employee has voluntarily resigned from his employment and from any and all
offices and positions he holds with the Employer Entities.

                  3. Subject to continuing satisfaction of the terms and
conditions of this Agreement by Employee and all Employee Affiliates (as defined
below), Employer shall cause the following payments and adjustments (the
"Payments") to be made to and on behalf of the Employee upon the expiration of
the seven-day period referred to in Section 20 hereof:

                     A payment equal to two times Employee's current annual base
salary.

                     Furthermore,  if  enrolled  in  the  Pactiv  medical  and
basic  life  insurance  plans  at the Termination Date, continued coverage under
the Pactiv medical and basic life insurance plans as they may be amended from
time to time will be offered to Employee and Employee's eligible dependents on
an optional basis with the Employee sharing the cost (after-tax basis) until
February 28, 2001. Employee will remain responsible for any employee
contribution required by his medical coverage choice. In the event Employee
enrolls in a group medical plan of a new employer before the end of his
continuation period, his new coverage will be primary and Pactiv medical
coverage will be secondary as provided in the medical plan. Unless Employee is
covered by another group medical plan at the expiration of the continuation
period, he shall be able to continue, completely at his own expense, Pactiv
medical coverage for up to an additional eighteen months under the rules
applicable to COBRA coverage.

<PAGE>   2
                  Employee acknowledges and agrees that the Payments are in full
and complete satisfaction of any and all liabilities or obligations Employer has
or may have to Employee. The Payments shall be in lieu of any other payments,
wages, cost of living adjustments, and benefits, except as expressly provided in
this Agreement. If the Employee fails to execute this Agreement by February 19,
2000 (a date at least 21 days after Employee received it), or revokes or cancels
this Agreement during the seven-day period referred to in Section 19, Employer
shall not be obligated to make the Payments to Employee. If Employee revokes or
cancels the Agreement after Employer has made any portion of the Payments,
Employee shall be obligated to return to Employer all benefits and payments
provided to him under this Agreement.

                  Without limiting the generality of the foregoing, it is
expressly provided that, except as provided in the remainder of this Section 3,
the Payments are in full and complete satisfaction of any and all liabilities or
obligations which any Employer Entity, including any plan, fund or program
sponsored, maintained or contributed to by an Employer Entity, has or may have
to Employee under or with respect to any employee benefit plan described in
Section 3(3) of the Employee Retirement Income Security Act of 1974, as amended
("ERISA"), any payment or other item excluded from the definition of "employee
welfare benefit plan," "employee pension benefit plan" or "employee benefit
plan" under the rules of 29 C.F.R. Section 2510.3-1, 2510.3-2 or 2510.3-3, as
the case may be, and any employee benefit plan described in Section 4 of ERISA.

                  Notwithstanding any other provisions of this Agreement, the
Employee, and his beneficiaries and dependents as applicable, shall retain his
entitlement to: (i) any and all benefits to which he is entitled under the terms
of any plan maintained or contributed to by an Employer Entity which is
qualified under Section 401(a) of the Internal Revenue Code of 1986, as amended
(the "Code") and (ii) any continuation of health or medical coverage at the
Employee's, beneficiary's or dependent's expense, to the extent required by the
relevant provisions of the Consolidated Omnibus Budget Reconciliation Act of
1985.

                  The Payments shall be subject to any and all applicable
withholding and other employment taxes.

                  4. Employee acknowledges that he was privy to and received
trade secret, confidential, proprietary, and other non-public information
belonging to Employer Entities and agents, joint venturers, contractors,
customers, vendors, and suppliers of Employer Entities ("Confidential
Information"). Employee further acknowledges that this Confidential Information
is not generally known, derives value from not being generally known, and that
Employer Entities as well as third-party employees would be irreparably harmed
if such information were intentionally or inadvertently disclosed.

                  Employee therefore agrees that he shall maintain in the
strictest confidence and will not, directly or indirectly, use, intentionally or
inadvertently, publish or otherwise disclose to any person or entity whatever,
any Confidential Information, regardless of its form without the prior written
explicit consent of Employer, to be provided by the General Counsel of Pactiv.
Employee

                                      -2-
<PAGE>   3
shall take reasonable precautions to protect against the inadvertent
disclosure of Confidential Information. Employee's obligations under this
Agreement with respect to Confidential Information shall extend for the period
that such information is not generally known outside any of the Employer
Entities for reasons other than disclosure or disclosures made by or on behalf
of Employee, or for 24 months from the date of execution of this Agreement,
whichever is sooner. All duties and obligations set forth in this Agreement
shall be in addition to those which exist under statute and at common law and
shall not negate but shall be in addition to or coextensive with those
obligations arising under any agreements or documents executed by Employee
during his employment with Employer. Should Employee be served with legal
process seeking to compel disclosure of any such information, Employee shall
notify the General Counsel of Pactiv immediately.

                  5. Employee further acknowledges that he inevitably would
disclose Confidential Information, including trade secret information, should he
serve as director, officer, manager, supervisor, consultant, independent
contractor, owner of greater than 1% of the stock, representative, agent, or
employee (where Employee's duties as an employee would involve any level of
strategic, advisory, technical, creative, or other similar input) for any
competitor of Employer or any other Employer Entity involved in the packaging
industry.

                  6. In light of Employee's acknowledgments regarding
Confidential Information set forth in paragraphs 4 and 5, and as additional
consideration in return for the Payments described in Section 2, Employee agrees
that, for a period of two years following the date of Employee's resignation
from Employer:

                     a.  Employee shall not, without Employer's express, written
consent, to be provided by the General Counsel of Pactiv , directly or
indirectly, by himself or for or on behalf of any other individual, business, or
entity serve as director, officer, manager, supervisor, or shareholder (of other
than a passive investment of less than 1% of the individual's, business', or
entity's outstanding publicly-traded stock), consultant, independent contractor,
representative, agent, or employee (where Employee's duties for the competitor
as employee include any level of strategic, advisory, technical, creative, or
other similar input) for any individual, business, or other entity that
manufactures, markets, sells, supplies, or distributes products within the same
market in which Pactiv currently manufactures, markets, sells, supplies, or
distributes such products;

                     b.  Employee shall not, without Employer's express,
written consent, to be provided by the General Counsel of Pactiv , in any
capacity, whether on behalf of himself or any other entity, counsel or advise
any entity with whom Employee had contact, communication, knowledge, or other
interaction of any kind while employed by any Employer Entity in matters
directly or indirectly involving the Employer Entity;

                     c.  Employee shall not, without the express,  written
consent to be provided by the General Counsel of Pactiv , contact any employee
of any Employer Entity for purposes of recruiting or placing such individual
with another employer or influencing him or her to terminate employment with any
Employer Entity;

                                      -3-
<PAGE>   4
                     d.   In the event that an employee of an Employer
Entity contacts  Employee in contemplation or for the purpose of seeking
employment with another employer or terminating his or her employment with such
Employer Entity, Employee shall not enter into any discussions with such
employee regarding that matter without Employer's express, written consent, to
be provided by General Counsel of Pactiv ;

                     e.   Furthermore,  Employee may not directly or indirectly
extend an offer of employment or cause an offer of employment to be extended to
an employee or a person who within the 90 days preceding the extension of such
offer was an employee of an Employer Entity without Employer's express, written
consent, to be provided by General Counsel of Pactiv. Employee acknowledges that
the duration and scope of each of the above restrictions and limitations
(including, but not limited to, the time periods) is fair, reasonable, and
necessary to protect the Employer Entities' interests, including their interests
in Confidential Information set forth above. Further, Employee agrees to waive
any claim to contest the reasonableness of such restrictions. Employee also
acknowledges that the above restrictions and obligations will not prevent
Employee from earning a livelihood or obtaining gainful employment.

                  7. Employee agrees to turn over to Employer by the Termination
Date all expense reports, notes, memoranda, records, documents, Employer
manuals, credit cards, pass keys, computers, office equipment, sales records and
data, and all other information or property, no matter how produced, reproduced
or maintained, which is kept by Employee in his possession, or is used in or
pertaining to the business of Employer or any Employer Entity, including but not
limited to confidential materials or information obtained by him in the course
of his employment.

                  8. Except as otherwise required by law or by a court of
competent jurisdiction, Employee agrees never to disclose or discuss the terms,
conditions and amounts set forth in this Agreement or the discussions and
negotiations that preceded it, except to his attorneys and financial advisors
(collectively, the "Employee Affiliates") as necessary for the Employee
Affiliates to assist him; provided, however, that Employee agrees that prior to
any disclosure to an Employee Affiliate, Employee shall inform such Employee
Affiliate of the confidential nature of the Agreement and the discussions and
negotiations that preceded it; and provided, further, that Employee agrees that
the Agreement and the discussions and negotiations that preceded it will be kept
confidential by each of the Employee Affiliates except as required by law or a
court of competent jurisdiction. Neither Employee, any Employee Affiliate, nor
anyone else on their behalf intentionally and in public will disparage Employer
or any Employer Entity, or any of their directors, officers, employees,
attorneys or agents in their capacities as such. Employee will exhibit neutral
to positive actions or comments regarding Pactiv.

                  9. Employee shall use reasonable efforts to provide thorough
and accurate information and testimony voluntarily to or on behalf of any
Employer Entity, regarding any investigation or court case initiated by or
against any Employer Entity or by any government agency, but he agrees not to
disclose or to discuss with anyone who is not directing or assisting in any
Employer-Entity investigation or case, other than his attorney, the fact of or
the subject matter of any

                                      -4-
<PAGE>   5
investigation, except as required by law. Employee will use reasonable efforts
to accommodate his schedule to cooperate with the Employer Entity and promptly
provide such information. Any Employer Entity requesting information will
attempt to work with Employee to arrange times that reasonably accommodate him,
and such Employer Entity will reimburse Employee for commuting, parking or other
similar expenses and, to the extent permitted by law, will reasonably compensate
Employee for any significant imposition on his time by any Employer Entity
requesting such information.

                  10. Employee agrees to take reasonable steps to insure that
any statements, writing, speeches or comments that he may make, prepare or
deliver, be fully consistent with his covenants under this Agreement, and that
any such statements, writings, speeches or comments that in any way relate to
any of the Employer Entities, or any of their attorneys, agents, employees,
officers or directors, or to his employment with Employer, will be accompanied
by appropriate disclaimers indicating that he is not authorized to speak on
behalf of or as a representative or agent of any Employer Entity, and that any
such statements, writings, speeches or comments do not in any way necessarily
reflect any Employer Entity's positions.

                  11. EMPLOYEE HEREBY RELEASES, FOREVER DISCHARGES AND COVENANTS
NOT TO SUE ANY EMPLOYER ENTITY AS DEFINED IN SECTION 1 HEREOF, ANY PREDECESSOR,
JOINT VENTURE AND PARENT OF ANY EMPLOYER ENTITY, AND ANY AND ALL OF THEIR
RESPECTIVE PAST OR PRESENT OFFICERS, DIRECTORS, PARTNERS, INSURERS, AGENTS,
ATTORNEYS, EMPLOYEES, TRUSTEES, ADMINISTRATORS AND FIDUCIARIES (ALL
COLLECTIVELY, THE "RELEASED PARTES"), FROM ANY AND ALL MANNER OF ACTIONS, CAUSES
OF ACTION, DEMANDS, CLAIMS, AGREEMENTS, PROMISES, DEBTS, LAWSUITS, LIABILITIES,
RIGHTS, DUES, CONTROVERSIES, COSTS, EXPENSES AND FEES WHATSOEVER, WHETHER
ARISING IN CONTRACT, TORT OR ANY OTHER THEORY OF ACTION, CHOATE OR INCHOATE,
MATURED OR UNMATURED, CONTINGENT OR FIXED, LIQUIDATED OR UNLIQUIDATED, ACCRUED
OR UNACCRUED, ASSERTED OR UNASSERTED, FROM THE BEGINNING OF TIME UP TO THE DATE
OF THIS AGREEMENT (COLLECTIVELY, "CLAIMS"), EXCEPT FOR THOSE OBLIGATIONS CREATED
BY OR ARISING OUT OF THIS AGREEMENT AND THOSE OBLIGATIONS SPECIFICALLY EXCLUDED
UNDER SECTION 3 OF THIS AGREEMENT. EMPLOYEE EXPRESSLY WAIVES THE BENEFIT OF ANY
STATUTE OR RULE OF LAW WHICH, IF APPLIED TO THIS AGREEMENT, WOULD OTHERWISE
EXCLUDE FROM ITS BINDING EFFECT ANY CLAIM AGAINST ANY RELEASED PARTY NOT NOW
KNOWN BY EMPLOYEE TO EXIST. EXCEPT AS NECESSARY FOR EMPLOYEE TO ENFORCE THIS
AGREEMENT, THIS AGREEMENT IS INTENDED TO BE A GENERAL RELEASE AND A COVENANT NOT
TO SUE THAT EXTINGUISHES ALL CLAIMS AND PRECLUDES ANY ATTEMPT BY EMPLOYEE TO
INITIATE ANY LITIGATION AGAINST ANY RELEASED PARTY. IF EMPLOYEE COMMENCES OR
CONTINUES ANY CLAIM IN VIOLATION OF THIS AGREEMENT, THE RELEASED PARTY SHALL BE
ENTITLED TO ASSERT THIS AGREEMENT AS A BAR TO SUCH ACTION OR PROCEEDING AND
SHALL BE ENTITLED

                                      -5-
<PAGE>   6
TO RECOVER ITS ATTORNEY FEES AND COSTS OF LITIGATION FROM THE
PARTY COMMENCING OR CONTINUING THE CLAIM, INCLUDING REASONABLE COMPENSATION FOR
THE SERVICES OF THE INTERNAL PERSONNEL OF THE RELEASED PARTY. EMPLOYEE
UNDERSTANDS AND ACKNOWLEDGES THAT HE IS WAIVING ALL CLAIMS RELATED TO HIS
RESIGNATION AND HIS DECISION TO RESIGN AS OF THE TERMINATION DATE.

                  12. Without in any way limiting the generality of the
foregoing, this Agreement constitutes a general and full release and disclaimer
of all claims arising out of or relating in any way to Employee's employment or
termination of employment with Employer and all other Employer Entities, whether
arising under a statute including, but not limited to, Title VII of the Civil
Rights Act of 1964, the Age Discrimination in Employment Act of 1967, 42 U.S.C.
ss. 1981 ("Section 1981"), the Americans With Disabilities Act ("ADA"), the
Family and Medical Leave Act ("FMLA"), the Worker Adjustment and Retraining
Notification Act ("WARN"), Illinois Human Rights Act, all county, municipal,
federal, state or other statutes, ordinances or regulations, as may be amended
from time to time, or common law claims or causes of action relating to alleged
discrimination, breach of contract or public policy, wrongful or retaliatory
discharge, tortious action, inaction, or interference of any sort, defamation,
libel, slander, invasion of privacy, intentional or negligent infliction of
emotional distress, personal or business injury, including attorneys' fees and
costs, all claims for salary, bonus, vacation pay, and reimbursement for
expenses, occurring up to and including the date of execution of this Agreement.

                  13. This Agreement constitutes the entire agreement and
understanding between the parties with regard to all matters, including but not
limited to Employee's employment, his voluntary resignation from Employer,
payments owed to him, and the other subject matters addressed in this Agreement.
This Agreement supersedes and replaces all prior commitments, negotiations and
all agreements proposed or otherwise, whether written or oral, concerning the
subject matters contained in this Agreement. This Agreement is an integrated
document and the consideration stated herein is the sole consideration for this
Agreement.

                  14. The parties agree that damages incurred as a result of a
breach of this Agreement will be difficult to measure. It is, therefore, further
agreed that, in addition to any other remedies, equitable relief will be
available in the case of breach of this Agreement. It is also agreed that, in
addition to any other remedies, in the event of a breach of this Agreement by
Employee or an Employee Affiliate, Employer may withhold and retain all or any
portion of the Payments and shall be entitled to liquidated damages from
Employee in an additional amount equal to any portion of the Payments which it
so withholds and retains.

                  15. In the event of litigation in connection with or
concerning the subject matter of this Agreement, the prevailing party shall be
entitled to recover all costs and expenses of litigation incurred by it,
including such party's reasonable attorneys' fees and reasonable compensation
for the services of its internal personnel.

                                      -6-
<PAGE>   7
                  16. If any provision, section, subsection or other portion of
this Agreement shall be determined by any court of competent jurisdiction to be
invalid, illegal or unenforceable in whole or in part, and such determination
shall become final, such provision or portion shall be deemed to be severed or
limited, but only to the extent required to render the remaining provisions and
portion of this Agreement enforceable. This Agreement as thus amended shall be
enforced so as to give effect to the intention of the parties insofar as that is
possible. In addition, the parties hereby expressly empower a court of competent
jurisdiction to limit or modify any term or provision of this Agreement to the
extent necessary to comply with existing law and enforce this Agreement as
modified.

                  17. This Agreement shall be deemed to have been executed and
delivered within the State of Illinois and the rights and obligations of the
parties shall be construed and enforced in accordance with, and governed by, the
laws of the State of Illinois without regard to that state's rules regarding
conflict of laws. The language of all parts of this Agreement shall in all cases
be construed as a whole, according to its fair meaning and not strictly for or
against any of the parties.

                  18. The parties agree that any dispute relating to this
Agreement or Employee's employment with Employer or the termination thereof
shall be submitted by the parties to, and decided by, the courts in Chicago,
Illinois.

                  19. This Agreement is being delivered to Employee on January
28, 2000. Employee shall have until at least 21 days after he receives the
Agreement to decide whether to sign the Agreement and be bound by its terms.

                  20. In addition, the parties agree that even after signing the
Agreement, Employee shall have the right to revoke or cancel it only within
seven days after signing it. This cancellation or revocation can be accomplished
by delivery of a written notification if Employee wishes to revoke the Agreement
to RICHARD L. WAMBOLD, CHIEF EXECUTIVE OFFICER, PACTIV CORPORATION, 1900 WEST
FIELD COURT, LAKE FOREST, ILLINOIS 60045. In the event that this Agreement is
canceled or revoked by Employee, Employer shall have no obligation to meet the
commitments described in this Agreement.

                  21. Employee acknowledges that he has been advised and
encouraged by Employer to consult his own attorney prior to signing this
Agreement, and that the Employee is executing this Agreement freely, knowingly
and voluntarily.
