SUBJ:    NEW BRANCH OFFICE LOCATION FOR CALIFORNIA COASTAL REGION AND CHANGE OF
         ADDRESS FOR FRED BROOKS.

      A.    TII now has an official office location for the California Coastal
            Region. It is in the town of Morro Bay, located quite near
            California Men's Colony and near San Luis Obispo.

      B.    This is also the new residence for Fred Brooks, the Branch Manager.

      C.    The new address and telephone number is:

                              2573 GREENWOOD AVENUE
                           MORRO BAY, CALIFORNIA 93442
                           TEL. AND FAX: 805-771-8159

      D.    TII has agreed to pay half of the rent for this location since it is
            an office as well as a residence. Please see that Fred receives this
            payment by the first of the month. The total rent it: $1,150.00 /
            month, so that would mean that we pay Fred

                                     $575.00

            as rent. Please pay him prior to the first of the month.

      E.    At this moment, Fred is having problems with the new telephone line.
            He is trying to get this corrected today. He is able to receive
            calls, and can call locally or in 800 numbers, but otherwise cannot
            call (or FAX) outside the 805 area code.

      F.    I have asked him to FAX in the latest time sheets from some local
            store such as Kinko's.

right to possession of the Premises. Any failure by Tenant to comply with one or
more of such terms shall constitute a default hereunder and Landlord may
terminate Tenant's right to possession of the Premises and/or forfeit this
Agreement, in any manner provided by law.

      FURTHER, TENANT AGREES THAT:

1.    Term/Beginning Date: The Term of this tenancy, for the Premises described

      be prorated to the first day of the succeeding month. Should Tenant fail
      to pay an installment of rent of any portion thereof, when due, Tenant
      shall pay the amount designated in Section E. to Landlord, as a Late Rent
      Charge. At Landlord's election, such Charge shall be deemed additional
      rent for such rental month and collected as such, or landlord may deduct
      such Charge from Tenant's Security Deposit. Any claim by Tenant for a
      refund of the Security Deposit shall be deemed compensated to the extent
      of any deduction of such Charge. Such Charge shall be deemed Liquidated
      Damages in as much as Landlord's damages (preparation of notice, service
      of notice, collection attempts, extra man-hours and bookkeeping, etc.)
      would be impracticable or extremely difficult to compute under
      C.Css.ss.1670, 1671 and C.C.P.ss.1951.5.

3.    Security Deposit: Tenant shall deposit with Landlord the amount designated
      in Section F to secure Tenant's compliance with all of the conditions of
      this Agreement and Landlord's Rules and Regulations, if any. The Deposit
      shall not be deemed rent for any rental month, unless Landlord so elects,
      nor shall it constitute a measure of Landlord's damages in the event of a
      default by Tenant. Tenant shall not be entitled to any Interest on this
      Deposit, nor of any deposit made under this Agreement. In the event of a
      default by Tenant under the conditions of this agreement or Landlord's

      Landlord within 3 days, Landlord may deem such failure a default under

      of the tenancy, for any reason whatsoever, as much of the Deposit as is
      reasonably necessary shall be used for repair of the Premises and its
      appurtenances, over and above normal wear and tear, and to compensate
      Landlord for any unpaid rent or Liquidated Damages. If the Deposit is
      insufficient for such purpose, Landlord, may proceed with collection of
      the deficiency from Tenant. Acceptance of a refund of all or a portion of
      the Deposit, by Tenant, shall constitute a full and final release of
      Landlord from any and all claims of Tenant, of any nature whatsoever.

4.    Minimum Tenancy: Unless a different period is designated in Section G.
      Tenant shall be liable to Landlord for rent for a period of 6 consecutive
      months following the Beginning Date hereof, if Tenant's tenancy is

      compensation to the extent of any such application of the Security
      Deposit. The amount so applied shall be deemed Liquidated Damages in as
      much as Landlord's damages (lost rent, cost of advertising, re-rental,
      etc.) would be impracticable or extremely difficult to computer under
      C.C.ss.ss.1670, 1671 and C.C.P.ss.1951.5. II Tenant's tenancy is
      terminated by Landlord under Paragraph 15 hereof, this paragraph shall not
      apply.

5.    Premises Preparation Charge: Tenant shall pay to Landlord the amount
      designated in Section I, as a Premises Preparation Charge. Such Charge
      constitutes a part of the consideration paid by Tenant for the rental of
      the Premises and it shall not be deemed to be a payment or deposit made to
      secure the performance of Tenant's obligations under this Agreement.

6.    Utilities: Tenant shall pay for all utilities and/or services supplied to
      the Premises, except those designated in Section J. In the event of any
      --- in the payment of rent by Tenant, if feasible, Landlord may instruct

RE:   CREDIT FACILITY

Dear Guenter:

      This letter agreement is intended to formalize our proposal to increase by
$100,000 the current funding provided by Biomed Solutions, LLC ("Biomed") to
Biophan Technologies, Inc. ("BIPH") (the "Loan") in accordance with the
following terms and conditions:

      1.    The proceeds from the Loan will be utilized to satisfy certain
            obligations, including payment of American Express charges, payroll
            and for general working capital.

      2.    Except as provided herein, the Loan shall have the same terms and
            conditions as the first credit facility in the amount of $250,000.

      3.    The credit facility documents dated June 4, 2002 shall be amended to
            extend until December 1, 2002 (rather than September 1, 2002) the
            time by which BIPH must repay Biomed the amounts it currently owes
            Biomed. Biomed will receive warrant coverage for this extension as
            provided in paragraph 6 of the Credit Agreement.

      4.    Paragraph 3(b) of the Convertible Promissory Note dated June 4, 2002
            shall be amended to read as follows: "The conversion price shall be
            equal to the lesser of (i) the closing big price on June 4, 2002;
            (ii) the closing bid price on the date of conversion; or (iii) the
            lowest per share purchase price paid by any third party between June
            4, 2002 and the conversion date."

      5.    Current warrants held by Biomed will be amended so that the exercise
            price associated with said warrants shall be as follows: the
            exercise price shall be equal to the lesser of (i) the closing bid
            price on June 4, 2002; (ii) the closing bid price on the date of
            exercise; or (iii) the lowest per share purchase price paid by any
            third party between June 4, 2002 and the exercise date.

<PAGE>

      6.    Biomed shall have the option to convert to common stock all or part
            of the amounts due to it by BIPH under the terms of the loan
            agreement. The conversion price shall be equal to the lesser of (i)
            the closing bid price on the date of closing of the Loan; (ii) the
            closing big price on the date of conversion; or (iii) the lowest per
            share purchase price paid by any third party between the closing of
            the Loan and the conversion date.

      7.    Repayment of the Loan to Biomed shall occur as soon as BIPH has
            sufficient cash flow, but, in no event lower than 12 months from the
            date of this letter agreement.

      8.    As additional consideration, BIPH shall pay to Biomed 33% of any
            revenue (cash, stock, property or other consideration) that it
            receives from the sale or licensing of its shielding or filtering
            technologies, up to a maximum of $300,000. Payments of principal on
            the Loan shall be credited toward the calculation of the $300,000
            ceiling.

      If you are in agreement with these terms and conditions, please execute
below and return a signed copy to me.

                                        Sincerely,

                                        BIOMED SOLUTIONS, LLC
