                                   LANCE, INC.

               2001 ANNUAL PERFORMANCE INCENTIVE PLAN FOR OFFICERS

Purposes and Introduction           The primary purposes of the 2001 Annual
                                    Performance Incentive Plan for Officers are
                                    to:

                                    o        Motivate behaviors that lead to the
                                             successful achievement of specific
                                             sales, financial and operations
                                             goals that support Lance's stated
                                             business strategy.

                                    o        Emphasize link between
                                             participants' performance and
                                             rewards for meeting predetermined,
                                             specific goals.

                                    o        Improve the competitiveness of
                                             total cash pay opportunities.

                                    o        Help establish performance
                                             orientation at Lance and
                                             communicate to employees that
                                             greater responsibility carries
                                             greater rewards because more pay is
                                             "at risk."

                                    For 2001, participants will be eligible to
                                    earn incentive awards based on Company
                                    performance in Earnings Per Share (EPS),
                                    Lance Co. operating profit, Subsidiary
                                    operating profit and individual performance
                                    objectives.

                                    To achieve the maximum motivational impact,
                                    plan goals and the rewards that will be
                                    received for meeting those goals will be
                                    communicated to participants as soon as
                                    practical after the 2001 Plan is approved by
                                    the Compensation Committee of the Board of
                                    Directors.

                                    Each participant will be assigned a Target
                                    Incentive Award, stated as a percent of Base
                                    Salary. The Target Incentive Award, or a
                                    greater or lesser amount, will be earned at
                                    the end of the plan year based on the
                                    attainment of predetermined goals.

                                    Following year-end, 100% of the awards
                                    earned will be paid to participants in cash.

Plan Year                           The period over which performance will be
                                    measured is the Company's fiscal year.

                                    Officers of Lance and Presidents of its
                                    Subsidiaries who are key to Lance's success.
                                    The Compensation Committee of the Board of
                                    Directors will review and approve
                                    participants nominated by the President and
                                    CEO.

                                    Participation in one year does not guarantee
                                    participation in a following year, but
                                    instead will be reevaluated and determined
                                    on an annual basis.

                                    Participants in the Plan may not participate
                                    in any other annual incentive plan (e.g.,
                                    sales incentives, etc.) offered by Lance or
                                    its affiliates. Attachment A includes the
                                    list of 2001 participants approved by the
                                    Compensation Committee at its January 29,
                                    2001 meeting.

Target Incentive Awards             Each participant will be assigned a Target
                                    Incentive Award expressed as a percentage of
                                    his or her Base Salary. Participants may be
                                    assigned Target Incentive Awards by position
                                    by salary level or based on other factors as
                                    determined by the President and CEO.

                                    Target Incentive Awards will be reevaluated
                                    at least every other year, if not annually.
                                    If the job duties of a position change
                                    during the year, or Base Salary is increased
                                    significantly, the Target Incentive Award
                                    shall be revised as appropriate.

                                    Attachment A lists the Target Incentive
                                    Award for each participant for the 2001 Plan
                                    Year. These Awards will be reviewed and
                                    adjusted annually by the Compensation
                                    Committee. Target Incentive Awards will be
                                    communicated to each participant as close to
                                    the beginning of the year as practicable, in
                                    writing. Final awards will be calculated by
                                    multiplying each participant's Target
                                    Incentive Award by the appropriate
                                    percentage (based on financial and
                                    individual performance for the year, as
                                    described below).

Individual Performance              Each Officer (other than those named in the
                                    last sentence of this paragraph and the
                                    first sentence of the next paragraph) will
                                    receive 75% of his or her Incentive Award
                                    based on Earnings Per Share. The remaining
                                    25% of each Officer's Incentive Award will
                                    be based upon the determination by the
                                    Compensation Committee in its discretion as
                                    to the individual performance of the Officer
                                    in meeting his or her individual goals for
                                    the year. Presidents of Subsidiaries will
