About Compensation and Benefits

Will the merger have any impact on fiscal year 2014 Annual Bonus awards or fiscal year 2015 merit increases and merit-based equity grants?

No. Fiscal year 2014 annual bonuses and 2015 merit increases will generally occur in the ordinary course of business consistent with past practice, and merit-based equity grants will be made to incent long term performance.

As previously communicated, the timing of fiscal year 2015 merit increases and equity grants for the field sales force will be accelerated and will now occur at the same time as the rest of the organization.

What will happen to my Forest fiscal year 2015 Annual Bonus?

Pursuant to the terms of the merger agreement, fiscal year 2015 annual bonuses will be prorated based on the number of days between the beginning of the company’s 2015 fiscal year (April 1, 2014) and the closing of the merger, assuming target performance. For a substantial majority of employees, “target performance” will mean the bonus that would be payable assuming an average performance rating of 3.5. For Corporate and Subsidiary officers who participate in the Forest Laboratories Annual Incentive Compensation Plan, “target performance” means your current target bonus.

For example, if the merger closed on July 1, 2014, the fiscal year 2015 annual bonus for an employee at the senior manager level would be calculated as follows:

Base Salary = $100,000

Bonus % assuming an average performance rating of 3.5 = 15% of base salary

Bonus proration for April 1 – June 30 = 25%

($100,000 × 15%) × 25% = $3,750

Forest fiscal Year 2015 bonus payments will be made no later than 60 days following the closing of the merger.

Does Actavis have a different fiscal/performance year than Forest?

Yes. Unlike Forest, Actavis operates on a calendar fiscal/performance year (January 1 – December 31). Following the closing of the merger, the Actavis fiscal/performance year will be retained.

Will I receive a bonus for the period of time following the closing of the merger through the end of the Actavis 2014 fiscal/performance year?

More specific information as to how bonuses will be calculated for Forest employees who remain employed with the combined company following the closing of the merger and who are eligible for a bonus will be shared at a later date.

What will happen to my retirement and health benefits following the closing of the merger?

In general, for at least one year following the closing of the merger, retirement and health benefits will be no less favorable, in the aggregate, than those offered to employees of Actavis. More information on specific benefits will be shared at a later date.

About Equity Awards

The following section describes the impact of the merger on outstanding Forest stock options, restricted stock awards, restricted stock unit (RSU) awards and performance share unit (PSU) awards (collectively, “equity awards”).

What does vesting mean?

Generally, vesting means that an award is no longer subject to risk of forfeiture. Typically, once a portion of your stock option award is vested, you may exercise shares underlying the vested portion of such option. Once a portion of your restricted stock and/or RSU award is vested, you may sell the shares with respect to the vested portion of such award.

What happens to my Forest equity awards upon the closing of the merger?

Pursuant to the terms of the merger agreement, upon the closing of the merger, all outstanding (vested and unvested) Forest equity awards will be converted into equivalent awards with Actavis, as described in more detail below. Shares of Actavis are traded on the New York Stock Exchange under the ticker symbol “ACT.” Following conversion, the equity awards will continue to be subject to the same terms and conditions as were in effect prior to the closing of the merger.

How will my outstanding equity awards be converted into equivalent Actavis awards?

Pursuant to the terms of the merger agreement, each outstanding Forest equity award will be converted into an equivalent Actavis equity award using the following conversion ratio:

1 Forest share = 0.4723 of an Actavis share

Stock option conversion:

Using the conversion ratio of 0.4723, below is an example of how 100 Forest stock options would convert into equivalent Actavis stock options, assuming a Forest exercise price of $37.88 and a hypothetical Actavis stock price of $200 on the day preceding the closing of the merger.

The value of your converted stock options will be substantially the same as they were immediately prior to the merger, subject to rounding of the number of shares underlying the option, the exercise price of the option as provided in the merger agreement and the market value of the shares of Actavis as to which they can be exercised.

To determine the number of Actavis stock options you will receive for each Forest stock option: Multiply the number of Forest stock options by 0.4723 (rounded down to the nearest whole share).	100 Forest options × 0.4723 = 47 Actavis options (47.23 options rounded down to the nearest whole share)
To determine the per share exercise price of your converted Actavis stock options: Divide the per share exercise price of the Forest stock option by 0.4723 (rounded up to the nearest cent).	$37.88 ÷ 0.4723 = $80.20 ($80.203 rounded up to the nearest cent)

Value of Forest Stock Options BEFORE Merger			Value of Actavis Stock Options AFTER Merger
FRX Stock Price	Exercise Price	# of Options	ACT Stock Price	Exercise Price	# of Options
$94.46*	$37.88	100	$200	$80.20 (rounded up to nearest whole cent)	47 (rounded down to nearest whole share)
($94.46 - $37.88) × 100 = $5,678			($200 - $80.20) × 47 = $5,631

* Implied FRX stock price = ACT price multiplied × 0.4723 ($200 × 0.4723 = $94.46)

Note: The above example is for illustrative purposes only and is not indicative of the value that you will receive for any stock option.

About Equity Awards

Restricted stock and RSU conversion:

Pursuant to the merger agreement, all unvested Forest restricted stock awards, PSUs and RSUs will convert into Actavis RSUs upon the closing of the merger. Using the conversion ratio of 0.4723, below is an example of how 100 Forest restricted stock awards would convert to equivalent Actavis RSUs, assuming a hypothetical Actavis stock price of $200 on the day preceding the closing of the merger.

To determine the number of Actavis RSUs that you will receive for each unvested FRX restricted stock award or RSU:   Multiple the number of unvested FRX awards that you hold by 0.4723. 100 Forest awards × 0.4723 = 47.23 Actavis RSUs

Value of Forest Restricted Stock Awards BEFORE Merger		Value of Actavis Stock Options AFTER Merger
FRX Stock Price	# of Awards	ACT Stock Price	# of Awards
$94.46*	100	$200	47.23
$94.46 × 100 = $9,446		$200 × 47.23 = $9,446

* Implied FRX stock price = ACT price multiplied × 0.4723

Note: The above example is for illustrative purposes only and is not indicative of the value of that you will receive for any restricted stock award or RSU.

Why, in the above examples, is the value of the restricted stock award fully preserved following the conversion while the value of the stock option is slightly less?

Due to certain accounting and tax considerations relating to the conversion of stock options, the merger agreement provides that stock options will be converted by rounding the number of shares subject to the option down to the nearest whole share and rounding the exercise price of the stock option up to the nearest whole cent. As a result of this rounding, the value of the stock option may be slightly reduced due to the conversion.

These considerations do not apply to restricted stock and restricted stock units, and therefore, those awards may be converted in a manner that fully preserves the value of the award.

What happens to my unvested equity awards if my job is eliminated or I am involuntarily terminated following the closing of the merger?

If, within three years following the closing of the merger, your employment is terminated under certain conditions, then all unvested equity awards granted to you prior to the closing of the merger, will become immediately vested and exercisable.

Severance

If I am separated from the company as a result of the merger with Actavis, will severance benefits be available?

For U.S. employees:

Pursuant to the terms of the merger agreement, Actavis has agreed to honor the terms of the Forest U.S. Severance Plan. Forest employees who are impacted by job elimination as a result of the combination with Actavis will be eligible for severance benefits to the extent provided for under the “change of control” provisions of the applicable Forest U.S. Severance Plan. Generally, the “change of control” provisions will apply to terminations of employment that occur within 12 months following the closing of the merger.

If I am offered a position that requires relocation and I do not accept the offer, will severance benefits still be available to me?

Pursuant to the terms of the Forest Severance Plan, relocation of your principal place of employment, without your consent, that is more than fifty (50) miles from its location immediately prior to the closing of the merger, will generally trigger the eligibility for severance benefits under the “change of control” provisions of the applicable Forest Severance Plan.

For Ex-U.S. employees:

Pursuant to the terms of the merger agreement, Actavis has agreed to honor any existing severance plans and, where none exist, severance benefits will follow the local statutory requirements.

If I am a Forest employee that has already received notification about a future separation date and I’m still working for the combined company following the closing of the merger, what level of severance benefits will I receive?

Forest employees located in the U.S. who are separated following the closing of the merger will be eligible for severance benefits to the extent provided for under the “change of control” provisions of the applicable Forest U.S. Severance Plan. Employees located outside the U.S. will be eligible for severance benefits to the extent provided for under any existing severance plan and, where none exists, severance benefits will follow the local statutory requirements.

If I am a former Aptalis employee that received and accepted an offer of continued employment with Forest, will severance benefits still be available to me?

Yes. Pursuant to the terms of the merger agreement, Actavis has agreed to honor the terms of the Forest U.S. Severance Plan. Forest employees who are impacted by job elimination as a result of the combination with Actavis will be eligible for severance benefits to the extent provided under the “change of control” provisions of the applicable Forest U.S. Severance Plan. If you are located outside the U.S., you will be eligible for severance benefits to the extent required under local law.

If I am an Aptalis employee that was not extended an offer of continued employment with Forest, will severance benefits still be available to me?

If you are an Aptalis employee that was not extended an offer of continued employment with Forest (including those individuals in the Pharmaceutical Technologies business), you will be eligible for the severance benefits under the terms of the Aptalis severance plan. Aptalis employees located outside the U.S. will be eligible for severance benefits in accordance with local statutory requirements.
