    1.1)  Parties.  The parties to this Agreement are James A. Weatherbee 
("Employee") and Techne Corporation ("Company").  As used herein, Company 
refers to Techne Corporation and its subsidiaries including Research and

of the rights and obligations created by this Agreement may be performed by or 
enforced by or against the Company or R&D or other appropriate subsidiary.

    1.2)  Term of Employment.  The Company hereby employs Employee as Vice 
President and Chief Scientific Officer of the Company for the term beginning 
July 1, 1995 and continuing through June 30, 1998 unless employment terminates 
earlier as provided in Article 5 hereof.

    1.3)  Duties and Supervision.  During the term of this Agreement, Employee 
agrees to devote his full time and best efforts to the business and affairs of 
the Company, and to perform such services and duties Employee may from time to 
time be assigned by the Company, and specifically its President.
			     
			     ARTICLE 2.
			   COMPENSATION

    2.1)  Salary.  During the first year of the term of this Agreement (July 
1, 1995 through June 30, 1996), the Company shall pay to Employee as base
compensation for services to be rendered hereunder an annual salary of 
$124,000, to be paid semi-monthly or in accordance with the usual payroll 
practices of the Company. Each subsequent year during the term of Employee's 
employment by the Company, under this Agreement, Employee's salary shall be 
reviewed but not reduced by the President of the Company.

    2.2)  Management Incentive Bonus Plan.  During each year of the term of 
Employee's employment, Employee shall be eligible to earn a bonus equal to 
40%, as herein defined, of his base compensation.  The performance standards 
for earning such bonus shall be established annually by the President of the
Company but the eligibility for a 40% bonus shall not be amended during the
term of this Agreement except with the consent of Employee.  At least one-half 
of such bonus shall be paid in the form of stock options with an aggregate 
exercise price equal to such one-half of the bonus amount.  Such options are 
to be granted on July 1 immediately after the close of the fiscal year and the 
exercise price is to be based on the market price of the Company's Common
Stock at the close of the fiscal year.  The other one-half of any bonus earned 
may be taken, at the election of the Employee, either in cash or in additional 
stock options with an exercise price equal to 170% of such one-half of the 
bonus amount.

    2.3)  Other Employee Compensation and Benefits.  In addition to the 
compensation and benefits provided to Employee in Sections 2.1 and 2.2 hereof, 
Employee shall be entitled to participate in other employee compensation and 
benefit plans from time to time established by the Company and made available 
generally to all employees.  Employee shall participate in such compensation 
and benefit plans on an appropriate and comparable basis determined by the 
Board of Directors by reference to all other employees eligible for 
participation.  With regard to all insured benefits to be provided to 
Employee, benefits shall be subject to due application by Employee, the 
Company has no obligation to pay insured benefits directly and such benefits 
are payable to Employee only by the insurers in accordance with their 
policies. Employee shall not be reimbursed for unused personal days or sick 
days.

			      ARTICLE 3.
		      PAYMENT OF CERTAIN EXPENSES

    3.1)  Business Expenses.  In order to enable Employee to better perform 
the services required of him hereunder, the Company shall pay or reimburse 
Employee for business expenses in accordance with polices to be determined 
from time to time by the Board of Directors.  Employee agrees to submit 
documentation of such expenses as may be reasonably required by Company.

			     ARTICLE 4.
      INVENTIONS, PROPRIETARY INFORMATION AND COMPETITION

    4.1)  Prior Agreement.  Neither the execution of this Agreement nor any 
provision in it shall be interpreted as rescinding or revoking the Employee 
Agreement With Respect To Inventions, Proprietary Information, and Unfair 
Competition previously entered into between the Company and Employee as of
August 29, 1995 (the "Prior Agreement").  The Company and Employee hereby 
agree that the terms of such Prior Agreement shall apply to all businesses of 
the Company, including not only business conducted by the Company but also to 
business conducted through Techne or any subsidiary or venture of Techne now
existing or hereafter created.  The termination of this Employment Agreement 
shall not terminate Employee's obligations under the Prior Agreement.

	       bonus continuation provisions of Article 6.1 of this Agreement 
	       are met.

	       (ii)  By written notice to Employee, the Company may terminate 
	       Employee's employment immediately with cause.  For purposes of 
	       this Agreement, "cause" shall mean material dishonesty or gross
	       misconduct on the part of Employee in the performance of 
	       Employee's duties hereunder, serious breach of Company policies 
	       or failure on the part of Employee to perform material duties
	       assigned to Employee by the Company's President or Board of 
	       Directors.

	       (iii)  Upon the occurrence of physical or mental disability of 
	       Employee to such an extent that Employee is unable to carry on 
	       essential functions of Employee's position, with or without 
	       reasonable accommodation, and such inability continues for a
	       period of three months.

    5.2)  Records and Files.  In the event of termination of employment of

termination an amount equal to one month's base salary as provided by section 
2.1 of this Agreement for each full year during which Employee has been 
employed by the Company.  For purposes of this Section 6.1, "change in 
control" means the acquisition in one or more transactions by a single party, 
or any number of parties acting in concert, of a majority of the outstanding 
shares of voting stock of the Company.

			      ARTICLE 7.
			    MODIFICATIONS

    7.1)  Modifications.  Except as provided in Section 4.1 above, this 
Agreement supersedes all prior agreements and understandings between the 
parties relating to the employment of Employee by the Company and it may not 
be changed or terminated orally.  No modification, termination, or attempted

Agreement shall be binding upon and inure to the benefit of the Company, its 
successors and assigns, and Employee, his heirs, assigns, and legal 
representatives.  The rights of Employee hereunder are personal and may not 
be assigned or transferred except as may be agreed to in writing by the

			     ARTICLE 10.
			     ARBITRATION

   10.1)  Arbitration.  Any dispute arising out of or relating to this 
Agreement or the alleged breach of it, or the making of this Agreement, 
including claims of fraud in the inducement, shall be discussed between the 
disputing parties in a good faith effort to arrive at a mutual settlement of 
any such controversy.  If, notwithstanding, such dispute cannot be resolved, 
such dispute shall be settled by binding arbitration.  Judgment upon the award
rendered by the arbitrator may be entered in any court having jurisdiction 
thereof.  The arbitrator shall be a retired state or federal judge or an 
attorney who has practiced securities or business litigation for at least 10 
years.  If the parties cannot agree on an arbitrator within 20 days, any party 
may request that the chief judge of the District Court for Hennepin County,
Minnesota, select an arbitrator.  Arbitration will be conducted pursuant to 
the provisions of this Agreement, and the commercial arbitration rules of the 
American Arbitration Association, unless such rules are inconsistent with the 
provisions of this Agreement, but without submission of the dispute to such
Association.  Limited civil discovery shall be permitted for the production of 
documents and taking of depositions.  Unresolved discovery disputes may be 
brought to the attention of the arbitrator who may dispose of such dispute.  
The arbitrator shall have the authority to award any remedy or relief that a 
court of this state could order or grant; provided, however, that punitive
or exemplary damages shall not be awarded.  The arbitrator may award to the 
prevailing party, if any, as determined by the arbitrator, all of its costs 
and fees, including the arbitrator's fees, administrative fees, travel 
expenses, out-of-pocket expenses and reasonable attorneys' fees.  Unless 
otherwise agreed by the parties, the place of any arbitration proceedings 
shall be Hennepin County, Minnesota.
			     
     IN WITNESS WHEREOF, the parties have executed this Agreement and caused 
it to be dated as of the day and year first above written.
