                  Re:      Terms of Employment

Dear Mr. Glenn:

      This letter is confirm the terms upon which you have agreed to accept
employment by Planet Technologies, Inc. (formerly known as Planet Polymer
Technologies, Inc.) as the President/CEO and the Chairman of the Board of
Directors on the following terms:

      1.    Duties. You shall perform the duties of President and Chief
Executive Officer of the Company and agree to serve on the Board of Directors
and act as the Chairman with the responsibilities and authority commonly held by
the president of a publicly held corporation, subject to the Bylaws of Planet
and limitations imposed by the Board of Directors or by law. You agree to devote
the majority of your fulltime efforts to the business of the Company.

      2.    Term. The term of your employment shall be for three (3) years and
you agree to serve for that term, subject to the direction of the Board of
Directors. The term of employment may be terminated only for cause by either you
or the Company.

      3.    Compensation and Benefits. You shall be compensated for such terms
as are reasonable for the position and industry, manageable within the financial
restrictions of the Company and approved by the Board of Directors. Subject to
the granting of the stock options described below, you have agreed to forego
salary or cash bonus until the Board of Directors determines that Planet can
reasonably afford to pay executive cash compensation, except for a salary of
$100.00 per month. The Company will pay for your healthcare and other benefits
that are customary for the Company and your position within the Company.

      4.    Stock Options. In exchange for your agreeing to forego your initial
cash compensation, you shall be granted a non-qualified stock option under the
Company's 2000 Stock Option Plan to purchase 3,480,729 shares of Planet common
stock (prior to adjustment for the reverse stock split contemplated in the Asset
Purchase Agreement with Allergy Free at an exercise price equal to the fair
market value on the date of this letter agreement). Thereafter the Company
agrees to grant to you stock options exerciseable at the then fair market value
at such times as may be required to maintain the aggregate number of stock
options granted to you at an amount not less than five percent (5%) of the
issued and outstanding common stock of Planet (on a fully diluted basis), during
the three-year term of employment. All options shall vest at the rate of 1/36th
per month, subject to acceleration as provided in the plan.

      5.    Confidentiality and Proprietary Rights. Prior to commencing
employment, you agree to enter into the Company's Confidentiality and
Proprietary Rights Agreement in the form customarily used by the Company for
executive officer positions.
