SHARES TENDERED AT A PRICE DETERMINED BY YOU:

By checking one of the following boxes below INSTEAD OF THE BOX UNDER “SHARES TENDERED AT A PRICE DETERMINED PURSUANT TO THE OFFER,” you are tendering shares at the price checked. This action would result in none of your shares being purchased if the Selected Price (as defined below) is less than the price checked below. If you want to tender portions of your shares at more than one price, you must complete a separate Letter of Transmittal for each price at which you tender shares. The same shares cannot be tendered at more than one price.

☐ By checking THIS ONE BOX INSTEAD OF ONE OF THE PRICE BOXES ABOVE, you are tendering shares and are willing to accept the Selected Price in accordance with the terms of our Offer. This action will maximize the chance of having Silgan Holdings Inc. purchase your shares (subject to the possibility of proration). Note that this could result in your receiving a price per share as low as $45.50.

ODD LOTS

As described in Section 1 of the Offer to Purchase, under certain conditions, stockholders holding fewer than 100 shares may have all of their shares accepted for payment before any proration of other tendered shares.

This preference is not available to partial tenders, or to beneficial or record holders of an aggregate of 100 or more shares, even if these holders have separate accounts representing fewer than 100 shares. Accordingly, this

2

section is to be completed only if shares are being tendered by or on behalf of a person owning, beneficially or of record, an aggregate of fewer than 100 shares. The undersigned either (check one box):

☐ is the beneficial or record owner of fewer than 100 shares in the aggregate, all of which are being tendered; or

☐ is a broker, dealer, commercial bank, trust company, or other nominee that (a) is tendering for the beneficial owner(s) shares with respect to which it is the record holder, and (b) believes, based upon representations made to it by the beneficial owner(s), that each such person is the beneficial owner of an aggregate of fewer than 100 shares and is tendering all of such shares.

In addition, the undersigned is tendering shares either (check one box):

☐ at the Selected Price; or

☐ at the price per share indicated above in the section captioned “Price per Share at which Shares Are Being Tendered.”

CONDITIONAL TENDER

(See Instruction 13)

You may condition your tender of shares on our purchasing a specified minimum number of your tendered shares, all as described in Section 6 of the Offer to Purchase. Unless the minimum number of shares you indicate below is purchased by us in our Offer, none of the shares you tender will be purchased. It is your responsibility to calculate that minimum number of shares that must be purchased if any are purchased, and you are urged to consult your own tax advisor before completing this section. Unless the following box has been checked and a minimum number of shares specified, your tender will be deemed unconditional.

☐ The minimum number of shares that must be purchased, if any are purchased, is:                              shares.

If, because of proration, the minimum number of shares that you designated above will not be purchased, we may accept conditional tenders by random lot, if necessary. However, to be eligible for purchase by random lot, you must have tendered all your shares and checked the following box:

☐ The tendered shares represent all shares held by me.

The method of delivery of this document is at the option and risk of the tendering stockholder. If you decide to make delivery by mail, we recommend you use registered mail with return receipt requested, properly insured. In all cases, sufficient time should be allowed to assure delivery.
