Ladies and Gentlemen:

The undersigned hereby tenders to Seneca Foods Corporation, a New York corporation (“Seneca”), upon the terms and subject to the conditions set forth in its Offer to Purchase dated February 8, 2021 and the related Letter of Transmittal (which, together with any amendments or supplements thereto, collectively constitute the “Offer”), receipt of which is hereby acknowledged, the number of shares of Class A common stock of Seneca, $0.25 par value per share (the “Class A Shares”), listed below, pursuant to the guaranteed delivery procedures set forth in Section 3 of the Offer to Purchase.

Number of Class A Shares to be tendered:         Class A Shares.

NOTE: SIGNATURES MUST BE PROVIDED WHERE INDICATED BELOW

PRICE (IN DOLLARS) PER CLASS A SHARE AT WHICH CLASS A SHARES ARE BEING TENDERED
(See Instruction 5 to the Letter of Transmittal)

THE UNDERSIGNED IS TENDERING CLASS A SHARES AS FOLLOWS (CHECK ONLY ONE BOX UNDER (1) OR (2) BELOW):

(1)

CLASS A SHARES TENDERED AT PRICE DETERMINED UNDER THE OFFER

By checking the box below INSTEAD OF ONE OF THE BOXES UNDER “Class A Shares Tendered At Price Determined By Stockholder,” the undersigned hereby tenders Class A Shares at the purchase price as shall be determined by Seneca in accordance with the terms of the Offer.

☐

The undersigned wants to maximize the chance that Seneca will accept for payment all of the Class A Shares the undersigned is tendering (subject to the possibility of proration). Accordingly, by checking this box instead of one of the price boxes below, the undersigned hereby tenders Class A Shares at, and is willing to accept, the purchase price determined by Seneca in accordance with the terms of the Offer. The undersigned understands that this action will result in the undersigned’s Class A Shares being deemed to be tendered at the minimum price of $40.00 per Class A Share for purposes of determining the Final Purchase Price (as defined in the Offer to Purchase). This may effectively lower the Final Purchase Price and could result in the undersigned receiving a price as low as $40.00 per Class A Share.

(2)

CLASS A SHARES TENDERED AT PRICE DETERMINED BY STOCKHOLDER

By checking ONE of the following boxes INSTEAD OF THE BOX UNDER “Class A Shares Tendered At Price Determined Under The Offer,” the undersigned hereby tenders Class A Shares at the price checked. The undersigned understands that this action could result in Seneca purchasing none of the Class A Shares tendered hereby if the purchase price determined by Seneca for the Class A Shares is less than the price checked below.

☐   $40.00	☐   $40.25	☐   $40.50	☐   $40.75	☐   $41.00	☐   $41.25
☐   $41.50	☐   $41.75	☐   $42.00	☐   $42.25	☐   $42.50	☐   $42.75
☐   $43.00	☐   $43.25	☐   $43.50	☐   $43.75	☐   $44.00	☐   $44.25
☐   $44.50	☐   $44.75	☐   $45.00	☐   $45.25	☐   $45.50	☐   $45.75
☐   $46.00	​	​	​	​	​

CHECK ONLY ONE BOX UNDER (1) OR (2) ABOVE. IF MORE THAN ONE BOX IS CHECKED ABOVE, THERE IS NO VALID TENDER OF CLASS A SHARES.

A STOCKHOLDER DESIRING TO TENDER CLASS A SHARES AT MORE THAN ONE PRICE MUST COMPLETE A SEPARATE NOTICE OF GUARANTEED DELIVERY FOR EACH PRICE AT WHICH CLASS A SHARES ARE TENDERED. THE SAME CLASS A SHARES CANNOT BE TENDERED, UNLESS PREVIOUSLY PROPERLY WITHDRAWN AS PROVIDED IN SECTION 4 OF THE OFFER TO PURCHASE, AT MORE THAN ONE PRICE.

ODD LOTS
(See Instruction 14 to the Letter of Transmittal)

Under certain conditions, stockholders holding a total of fewer than 100 Class A Shares may have their Class A Shares accepted for payment before any proration of other tendered Class A Shares. This preference is not available to partial tenders or to beneficial or record holders of an aggregate of 100 or more Class A Shares, even if such holders have separate accounts or certificates representing fewer than 100 Class A Shares. Accordingly, this section is to be completed ONLY if Class A Shares are being tendered by or on behalf of a person owning, beneficially or of record, an aggregate of fewer than 100 Class A Shares. The undersigned either (check one box):

☐

is the beneficial or record owner of an aggregate of fewer than 100 Class A Shares, all of which are being tendered; or

☐

is broker, dealer, commercial bank, trust company or other nominee that (a) is tendering for the beneficial owner(s) Class A 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 Class A Shares and is tendering all such Class A Shares.

CONDITIONAL TENDER
(See Instruction 15 to the Letter of Transmittal)

A stockholder may tender Class A Shares subject to the condition that a specified minimum number of the stockholder’s Class A Shares tendered pursuant to the Letter of Transmittal must be purchased if any Class A Shares tendered are purchased, all as described in the Offer to Purchase, particularly in Section 6 thereof. Unless at least that minimum number of Class A Shares indicated below is purchased by Seneca pursuant to the terms of the Offer, none of the Class A Shares tendered will be purchased. It is the tendering stockholder’s responsibility to calculate that minimum number of Class A Shares that must be purchased if any are purchased, and Seneca urges stockholders to consult their own financial or tax advisors before completing this section. Unless this box has been checked and a minimum specified, the tender will be deemed unconditional.

☐

The minimum number of Class A Shares that must be purchased, if any are purchased, is:          Class A Shares.

If, because of proration, the minimum number of Class A Shares designated will not be purchased, Seneca may accept conditional tenders by random lot, if necessary. However, to be eligible for purchase by random lot, the tendering stockholder must have tendered all of his or her Class A Shares and checked this box:

☐

The tendered Class A Shares represent all Class A Shares held by the undersigned.
