EXHIBIT 10.13
                            AGREEMENT FOR SDS PRODUCT

AGREEMENT, dated September 1, 1996, between SPINTECH, INC., a Delaware
corporation, with its principal offices at 218 Dew Drop Road, York, Pennsylvania
17402 ("Spintech") and PRINCETON PMC, INC., a Delaware corporation, with its
principal offices at 44 Kean Road, Short Hills, New Jersey 07078 ("Princeton").

Background

Spintech is engaged in the business of inventing, designing, and securing
manufacturing for products for the health care field, obtaining patent
protection and governmental approval for such products and insurance protection
services in relation to such products.

Princeton is engaged in the business of evaluating products for the health care
field, arranging for cost effective manufacturing of products, product
development, and distribution of such products and promoting and marketing
products through distributors, dealers and others to end-users in the health
care field on a worldwide basis.

Spintech is the owner of all rights, title and interest in and to certain rights
covering the SDS product, and Princeton desires to obtain from Spintech an
exclusive right to distribute the SDS product to end-users in the waste disposal
and health care fields in the Territory as defined below.

Agreement

In consideration of the foregoing background and the mutual promises and
covenants contained herein, and intending to be legally bound, the parties agree
as follows:

1.    Definitions. As used herein, the term:

      (a) "Authorized Channels" shall mean all channels of sale and distribution
      to end-users in the waste disposal and health care fields, including but
      not limited to distributors, dealers, health care organizations, health
      care providers, clinics, conferences and mail order, except as may be
      otherwise specified on Exhibit "A".

      (b) "Exhibit A" shall mean the exhibit at the end of this Agreement.

      (c) "Product" shall mean the SDS product described on Exhibit "A",
      modifications and enhancements of such product, and any new products, if
      they are based on the patent(s) of the existing product, and if and to the
      extent this Agreement is modified in accordance with Paragraph 17 hereof.

      (d) "Patent Rights" shall mean all patent(s), whether issued or assigned
      in the Territory, issued or assigned to Spintech, with respect to the
      Product, all corresponding Letters Patent as patents issue, and the patent
      applications, all as listed on Exhibit "A", and the resulting patents
      claiming priority from or based on such Letters Patent, and all divisions,
      reissues, and extensions thereof now owned by Spintech or under which
      Spintech now has the right to grant licenses, except that any Patent
      Rights that also relate to new products may be included among the patent
      rights granted to another distributor to support its distribution rights
      for such new products, unless this Agreement is amended in accordance with
      Paragraph 17 hereof, to include such new products as part of the Product
      being distributed by Princeton.

      (e) "Territory" shall mean (i) North American continent, plus (ii) the
      rest of the entire world, other than those countries where Spintech has
      heretofore granted distribution rights to other distributors ("excluded
      countries") provided the rest of the world (other than excluded countries)
      shall be included in the Territory only if the minimum amounts of the
      Product to be purchased as described on Exhibit "A" are increased by an
      amendment to this Agreement to appropriately reflect the world-wide market
      for the Product, in which case Princeton may fulfill such increased
      minimum amounts by purchasing the Product for sales anywhere within the
      enlarged Territory. If a major customer of Princeton seeks sales rights
      within an excluded country, Spintech will use commercially reasonable
      efforts to include such country within the Territory, but such efforts
      shall not require Spintech to violate existing agreements or law.

2.    Granting of Distribution Rights.

      (a) Upon the terms and conditions set forth herein, Spintech hereby grants
      to Princeton the exclusive right under the Patent Rights:

            (i)   to purchase,  market and sell the Product through Authorized
                  Channels in the Territory;

            (ii)  to grant one or more subdistributorships of the Product
                  through one or more Authorized Channels within the Territory,
                  or any part thereof, as determined in Princeton's discretion.

      (b) All subdistributorships shall include the restrictions on Princeton,
      and the obligations of Princeton, contained in this Agreement and shall be
      subject to Spintech's rights hereunder. Princeton shall promptly notify
      Spintech in writing of any subdistributorship it signs or otherwise
      authorizes and shall furnish Spintech with such information about its
      subdistributorship, as Spintech may request. Spintech shall have the right
      to reject any subdistributor or customer based on its credit worthiness
      and such rejection shall not be capriciously exercised.

      (c) This grant shall not be construed as a license, by implication or
      otherwise, under any patent applications or patents owned by Spintech or
      under which Spintech has or acquires the right to grant Licenses.

      (d) This grant shall not be construed to create an agency or employment
      relationship between Spintech and Princeton or any of its sublicensees,
      each of whom is and shall remain an independent contractor.

3.  Payments.

      (a) In consideration for the rights herein granted and the exclusive right
      to purchase, market and sell the Product, Princeton shall pay Spintech the
      sums specified on Exhibit "A" with respect to each Product purchased by
      Princeton from Spintech. The sums shall be paid within thirty (30) days of
      the receipt by Princeton of Spintech's invoice for the Product purchased
      by Princeton from Spintech.

      (b) In consideration of the performance of Princeton's obligations
      pursuant to Paragraph 4(a) below, Spintech shall reimburse Princeton for
      all costs that Princeton reasonably incurs in performing such obligations,
      provided that any costs in excess of $500 shall first be approved by
      Spintech in writing.

      (c) In consideration of Princeton's obligations pursuant to Paragraph 4
      below, Spintech shall (i) pay Princeton a product management fee in the
      amount of $3,000 per month, payable on the last day of each month of the
      term of this Agreement, (ii) reimburse Princeton for the cost of a
      technical service representative to be seconded to Princeton pursuant to
      an arrangement with Arbutas to be negotiated during the term of this
      Agreement, (iii) furnish Princeton with 200 units of the Product for
      inventory in advance of actual orders from dealers and other customers,
      and (iv) pay, or reimburse Princeton, for producing advertising materials
      and a video presentation, once only, in an amount not to exceed $40,000;

      (d) If any government with jurisdiction over any part of the Territory
      imposes any taxes on any part of the payments required to be paid by
      Princeton to Spintech hereunder and requires Princeton to withhold such
      taxes from such payment, Princeton may deduct such taxes from such
      payments. Tax receipts indicating payments or withholding of such taxes on
      behalf of Spintech shall be promptly submitted to Spintech. Princeton
      shall cooperate with Spintech in determining the propriety of imposition
      of any such tax. This provision shall not apply to any franchise tax based
      on or measured by Princeton's net income; such taxes are Princeton's
      responsibility and payments to Spintech shall not in any event be reduced
      by such taxes.

      (e) If any government with jurisdiction over any part of the Territory
      imposes any exchange restriction on the payments required under this
      Agreement, an account in the name of Spintech shall be established in a


                                      -2-
<PAGE>

      financial institution of Spintech's choice in the Territory and all moneys
      due Spintech shall be paid into such account or at Spintech's election,
      payment shall be made to any account designated by Spintech that complies
      with such restriction.

4.    Princeton's Marketing and Other Obligations.

      (a) In addition to its obligations set forth in Paragraph 3 above,
      Princeton shall use its best efforts to exploit the right hereby created
      and to maximize sales of the Product. Such efforts shall include, but are
      not limited to, reviewing the Products from a technological point of view
      and ensuring that all aspects of mechanical, chemical, electrical,
      industrial and other engineering disciplines have been applied for this
      purpose; reviewing and evaluating all sources of raw materials, assemblies
      and systems needed for the production of the Product; identifying and
      selecting potential manufacturers to produce the Product in commercial
      quantities and on acceptable terms and conditions; ascertaining the
      interest of distributors, dealers, waste managers, health care
      institutions and facilities and end-users, both professional and
      paraprofessional, in the Product; and developing and implementing
      advertising, marketing and sales strategies and generally promoting the
      sale of the Products.

      (b) Reviewing and evaluating clinical studies of the Product and arranging
      for clinical lectures about the Product.

      (c) Performing field services as, when and where required to support the
      Product and the various entities within the Authorized Channels;
      considering, evaluating and recommending design changes to improve Product
      acceptance; furnishing services to customers, including warranty
      replacements or repairs; representing Spintech in dealings with
      contractors engaged by Spintech to produce, assemble, package and ship the
      Product; and generally taking such steps and doing such things as
      constitute Product management in the health care field.

      (d) Spintech shall provide Princeton, at Spintech's cost, with a mutually
      agreed upon quantity of the Product, to use as customer samples and to
      perform Princeton's obligations, as set forth in subparagraph (a) above.

5.    Confidential Information.

      Each party agrees that all confidential information and documentation made
      available or disclosed to it by the other party as a result of or related
      to this Agreement, and all negotiations therefor if they are conspicuously
      marked or transmitted with directions that identify them as "confidential"
      or "secret", shall be received and treated by the receiving party on a
      confidential and restricted basis. Such information and documentation
      shall not be disclosed to others unless and until they enter the public
      domain or are required to be disclosed to a government agency. In the
      later case, the receiving party, shall use its best efforts to have such
      agency protect such information and documentation from public disclosure
      or access.

6.    Marking; Use of Trade Name and Marks.

      (a) Princeton shall affix to the Product and to the packages containing
      the Product or to insertion slips placed inside each package with a
      Product a legible notice stating, in effect, that the Product is patent
      protected, in a form to be mutually agreed by the parties.

      (b) If the laws of any jurisdiction within the Territory specify any
      additional or other patent marking notices, Princeton shall cause the
      Product or the related packaging to be so marked.

      (c) This Agreement authorizes and approves the use by Princeton of
      Spintech's trade name or trademark in connection with the manufacturing,
      advertising, marketing or sale of the Product. Such authorization and


                                      -3-
<PAGE>

      approval, however, is subject to Princeton submitting all written
      materials containing such names and marks to Spintech for its consent as
      to form, which shall not be unreasonably withheld.

      (d) If Princeton wishes to market the Product under a trade name or
      trademark of which it is the author and consents to the use of such name
      or mark for such purpose, Princeton shall assign and set over to Spintech
      all of its right, title and interest in and to such name and mark.

7.    Duration and Termination or Cancellation.

      (a) Unless otherwise terminated or canceled as hereinafter set forth, this
      Agreement and the rights under Patent Rights shall continue in force for a
      period of seven (7) years from the date of this Agreement.

      (b) This Agreement and the rights granted herein may be extended on the
      terms and conditions to be mutually agreed upon prior to the expiration of
      this initial term. If no such agreement is reached, this Agreement and the
      rights granted herein shall automatically terminate at the end of the
      initial term or the extended term then in effect, as applicable.

      (c) If at any time Princeton defaults in fulfilling any obligations hereof
      and if such default is not cured within ten (10) days after written notice
      thereof is given by Spintech to Princeton in the case of a monetary
      default, or within thirty (30) days after written notice thereof is given
      by Spintech to Princeton in any other cases, this Agreement and the rights
      herein granted shall be canceled as of the end of the applicable notice
      period, without any further notice or other action required to be taken by
      Spintech. Princeton shall have the right to cure any such default up to,
      but not after, the end of the applicable notice period.

      (d) Spintech shall also have the right to cancel this Agreement by giving
      written notice of cancellation to Princeton if any one of the following
      events occurs, such cancellation being effective upon Princeton's receipt
      of such notice or five (5) days after such notice is mailed, whichever is
      earlier.

            (i)   liquidation  of Princeton or an  assignment by Princeton for
                  the benefit of its creditors;

            (ii)  insolvency or bankruptcy of Princeton,  whether voluntary or
                  involuntary;

            (iv)  failure of Princeton to satisfy any judgment against it; or

            (v)   appointment of a trustee or receiver for Princeton; or

            (vi)  failure of Princeton to purchase and pay for the minimum
                  amount of Product set forth on Exhibit "A".

      (e) The waiver of any default under this Agreement by Spintech shall not
      waive the right to cancel this Agreement for any subsequent or similar
      default and the exercise of the right of cancellation shall not impose any
      liability by reason of cancellation or have the effect of waiving any
      damages to which Spintech might otherwise be entitled.

      (f) The termination or cancellation of this Agreement shall not interfere
      with, affect or prevent the collection by Spintech of any and all sums of
      money due to it under this Agreement. Upon termination or cancellation of
      this Agreement for any reason, the payments required by Paragraph 3 to be
      made by Princeton, even if they are not yet due, shall become immediately
      due and payable.

      government authorities within the Territory if, as and when required by
      the relevant laws of any jurisdiction within the Territory or any
      subdivision of the Territory. Spintech shall assist and cooperate with
      Princeton in Princeton's efforts to obtain such approval or validation.

15.   Effective Date.

      This Agreement shall come into force and effect on the date of this
      Agreement. If the validity of this Agreement in any jurisdiction within
      the Territory depends on the approval of any cognizant government
      authority of such jurisdiction, this Agreement shall not become effective
      in such jurisdiction unless and until such approval(s) is given in
      accordance with the laws requiring such approval.

16.   Modification.

      This Agreement embodies all of the understanding and obligations between

      (a) it is made in  writing,  signed on behalf of each of the  parties by
      their respective proper officers thereunto duly authorized, and

      (b)  if  applicable,   it  is  approved  by  the  cognizant   government
      authorities of each jurisdiction within the Territory.

17.   Amendment for New Products.

      If Spintech develops a new product, based on the patents of the existing
      Product, and the new product is not merely a modification or enhancement
      of the existing Product, Spintech shall offer to Princeton a right of
      first refusal to include such new product in the Product by inviting
      Princeton to amend the terms and conditions of this Agreement so that they
      are at least as favorable to Spintech as the terms and conditions that may
      be offered by any other credible party seeking exclusive distribution
      rights for such new product, as follows:

      (a) Spintech shall submit the proposal from such other would-be
      distributor to Princeton in writing, and Princeton shall have the right to
      match or exceed such proposal by making a written offer to Spintech within
      thirty (30) days after Princeton's receipt of such proposal;


      (b) If Princeton matches or exceeds such proposal by making a written
      offer to Spintech within such 30-day period, this Agreement shall be
      deemed amended to incorporate the terms and provisions of Princeton's
      offer.

      (c) If Princeton fails to make a written offer to Spintech within such
      30-day period or submits an offer within such 30-day period that Spintech
      reasonably believes is less favorable to it than the proposal submitted by
      such other would-be distributor, Spintech shall notify Princeton in
      writing, and thereupon Spintech shall


                                      -7-
