Exhibit 4.1

                                 AMENDMENT NO. 1
                                       TO
                            STOCK PURCHASE AGREEMENT

      This Agreement of Amendment is made this 8th day of January 2006 by and
between Biophan Technologies, Inc. a corporation organized under the laws of the
State of Nevada, with its principal offices at 150 Lucius Gordon Drive, Suite
215, West Henrietta, New York 14586 (the "Company"), and SBI Brightline XI, LLC,
a California limited liability company with its principal offices at 610 Newport
Center Drive, Suite 1205, Newport Beach, California 92660 (the "Purchaser").

      Reference is made to that certain Stock Purchase Agreement dated as of the
27th day of May 2005 by and between the Company and the Purchaser (the "Stock
Purchase Agreement").

      Whereas the Company and the Purchaser desire to remove from the Stock
Purchase Agreement any ambiguity regarding the date and time at which the
Purchaser is obligated to purchase Tranche Shares (as such term is defined in
the Stock Purchase Agreement) and to make clear that the Tranche Closing Dates
(as such term is defined in the Stock Purchase Agreement), once determined by
the Company are not subject to negotiation between the Company and the
Purchaser.

      Now therefore, in consideration of the foregoing and for other good and
valuable consideration, the receipt and adequacy of which are hereby
acknowledged, the Company and the Purchaser hereby agreed that Section 3.1 of
the Purchase Agreement be and hereby is amended by deleting from the first
sentence thereof the words "unless the Company and the Purchaser have mutually
agreed on a different time or date with respect to such Closing" so that, as so
amended, Section 3.1 shall read in its entirety as follows:

      3.01 Subject to the satisfaction or waiver of the conditions precedent set
      forth in Sections 3.2 and 3.3, the closing of a purchase of Tranche Shares
      by the Purchaser pursuant to this Agreement (each, a "Closing") shall
      occur at 10:00 a.m. on the date specified in the Election Notice delivered
      by the Company with respect to such Tranche Shares (the time and date of
      the Closing of a particular Tranche is referred to herein as the "Tranche
      Closing Date"). Unless otherwise agreed by the Company and the Purchaser,
      each Closing shall occur at the offices of SBI, Newport Beach, California.

      Except as specifically amended hereby, the Stock Purchase Agreement shall
remain in full force and effect without addition or alteration.

      In witness whereof, the Company and the Purchaser have executed this
Agreement of Amendment as of the 8th day of January 2006.

    Chief Executive Officer                     Managing MemberAGREEMENT

      This AGREEMENT (this "Agreement") is made and entered into as of January
6, 2006, by and between Globetel Communications Corp., a Delaware corporation
(the "Company"), and the stockholder identified on the signature page hereto
(the "Purchaser").

      WHEREAS, the Company and the Purchaser are parties to a Subscription
Agreement, dated as of August 30, 2005 (the "Purchase Agreement"), pursuant to
which the Company issued and sold to the Purchaser certain convertible
promissory notes and warrants. Capitalized terms used and not defined in this
Agreement but defined in the Purchase Agreement shall have the respective
meanings set forth in the Purchase Agreement.

      NOW, THEREFORE, in consideration of the foregoing and other good and
valuable consideration, the receipt and sufficiency of which are hereby
acknowledged, the Company and the Purchaser agree as follows:

1.    Subject to the terms hereof, the Purchaser agrees to exercise in
      accordance with Section 6.2(b) the Class A Common Stock Purchase Warrant,
      dated August 30, 2005, it received pursuant to the Purchase Agreement (the
      "Warrant") on the Closing Date (as defined in Section 6.1). In
      consideration therefor, on the Closing Date, the Company will issue and
      deliver to the Purchaser a Common Stock Purchase Warrant in the form of
      Exhibit A (a "New Warrant"), entitling the holder thereof to purchase
      ___________ shares of Common Stock at a per share exercise price of $4.00,
      subject to adjustment as set forth in the New Warrant.

2.    The Company hereby grants the following registration rights to the
      Purchaser with respect to the shares of Common Stock issuable upon
      exercise of the New Warrant ("New Warrant Shares"):

      2.1.  Piggy-Back Registrations. If at any time following the date hereof
            the Company shall determine to prepare and file with the Commission
            a registration statement relating to an offering for its own account
            or the account of others of any of its equity securities, other than
            on Form S-8 to register equity securities issuable in connection
            with stock option or other employee benefit plans, then the Company
            shall send to the Purchaser written notice of such determination
            and, if within fifteen days after receipt of such notice, the
            Purchaser shall so request in writing, the Company shall include in
            such registration statement all or any part of such New Warrant
            Shares the Purchaser requests to be registered.

      2.2.  Demand Registration. Following the one year anniversary of the date
            hereof, if the Company has not filed a registration statement with
            the Commission to enable the Purchaser to resell New Warrant Shares,
            upon a written request therefor from the Purchaser, the Company
            shall prepare and file with the Commission a registration statement
            under the 1933 Act registering the New Warrant Shares which are the
            subject of such request for unrestricted public resale by the holder
            thereof.

<PAGE>

      2.3.  The New Warrant Shares shall be afforded all of the registration
            procedures and terms as are set forth in Sections 11.2 through 11.7
            of the Purchase Agreement as if they were "Registrable Securities"
            thereunder. The Company further agrees to make such filings as may
            be necessary to ensure the continued effectiveness of Registration
            Statement No. 333-130119 filed under which the Warrant Shares are
            registered for resale by the Purchaser until such time as such
            Warrant Shares have been sold thereunder.

3.    The Company hereby represents and warrants to the Purchaser as follows:

      (a)   Authorization; Enforcement. The Company has the requisite corporate
            power and authority to enter into and to consummate this Agreement
            and the transactions contemplated hereby and to carry out its
            obligations hereunder. The execution and delivery of this Agreement
            and the New Warrant by the Company and the consummation by it of the
            transactions contemplated thereby have been duly authorized by all
            necessary action on the part of the Company and no further action is
            required by the Company in connection therewith. Each of this
            Agreement and the New Warrant has been duly executed by the Company
            and, when delivered in accordance with the terms hereof, will
            constitute the valid and binding obligation of the Company,
            enforceable against the Company in accordance with their respective
            terms except (i) as limited by applicable bankruptcy, insolvency,
            reorganization, moratorium and other laws of general application
            affecting enforcement of creditors' rights generally and (ii) as
            limited by laws relating to the availability of specific
            performance, injunctive relief or other equitable remedies.

      (b)   Issuance of the Securities. The New Warrant Shares have been duly
            authorized and, when issued and paid for in accordance with the
            transfer of the New Warrant, will be duly and validly issued, fully
            paid and nonassessable, free and clear of all Liens other than
            restrictions on transfer under applicable securities laws. The
            Company has reserved from its duly authorized capital stock a number
            of shares of Common Stock for issuance upon exercise of the New
            Warrant.

      (c)   Bring Down of Certain Representations and Warranties. The Company
            hereby restates, as if first made as of and on the date of this
            Agreement, the representations and warranties set forth in the
            Purchase Agreement (as modified by the disclosure schedules to the
            extent they apply thereto) in Sections 5(a), (b), (d), (e), (f),
            (h), (i), (j), (k), (l), (m), (n), (o), (p), (q), (r), (s), (t),
            (u), (v), (w), (x), (y), (z), (aa), (bb), (cc), (dd) and (ee); with
            the understanding that for purposes of this Agreement the term
            "Transaction Documents" therein shall refer not only to such term as
            defined in the Purchase Agreement but also to this Agreement and the
            New Warrant.

                                       2
<PAGE>

4.    The Purchaser hereby represents and warrants as of the date hereof to the
      Company as follows:

      (a)   Authorization; Enforcement. The Purchaser has the requisite
            corporate power and authority to enter into and to consummate the
            transactions contemplated by this Agreement and to carry out its
            obligations under each. The execution and delivery of this Agreement
            by the Purchaser and the consummation by it of the transactions
            contemplated thereby have been duly authorized by all necessary
            action on the part of the Purchaser and no further action is
            required by the Purchaser in connection therewith. This Agreement
            has been duly executed by the Purchaser and, when delivered in
            accordance with the terms hereof, will constitute the valid and
            binding obligation of the Purchaser, enforceable against the
            Purchaser in accordance with their respective terms except (i) as
            limited by applicable bankruptcy, insolvency, reorganization,
            moratorium and other laws of general application affecting
            enforcement of creditors' rights generally and (ii) as limited by
            laws relating to the availability of specific performance,
            injunctive relief or other equitable remedies.

      (b)   Bring Down of Certain Representations and Warranties. The Purchaser
            hereby restates, as if first made as of and on the date of this
            Agreement, the representations and warranties set forth in the
            Purchase Agreement in Section 4.

5.    Right of First Refusal. Until the one year anniversary of the date hereof,
      the Purchaser shall be given not less than seven (7) business days prior
      written notice of any proposed sale by the Company of its Common Stock or
      other securities or debt obligations, except in connection with an equity
      or equity-linked capital raise of at least $30,000,000 underwritten by a
      nationally recognized middle market or bulge bracket investment bank (such
      an issuance shall be an "Excepted Issuance"). The Company may not include
      any terms or provisions in the subsequent placement whereby the Purchaser
      would be required to agree to any restrictions in trading as to any
      securities of the Company owned by the Purchaser prior to such subsequent
      placement, and the Company must provide registration rights as to the
      securities issuable in such subsequent placement which are similar in all
      material respects to the registration rights contained in the Purchase
      Agreement. Should the Purchaser exercise its rights pursuant to this
      Section 5, the Purchaser shall have the right during the seven (7)
      business days following receipt of the notice to purchase all of such
      offered Common Stock, debt or other securities in accordance with the
      terms and conditions set forth in the notice of sale. In the event such
      terms and conditions are modified during the notice period, the Purchaser
      shall be given prompt notice of such modification and shall have the right
      during the seven (7) business days following the notice of modification to
      exercise such right. After the expiration of such seven (7) business day
      period, should the Purchaser choose not to exercise its right pursuant to

                                       3
<PAGE>

      this Section 5, the Company shall, within twenty-one (21) days, publicly
      announce either the entering into of definitive agreements (and attach
      such agreements along with such public filing) with respect to such
      proposed sale of Common Stock (or equivalents thereof or securities
      convertible into Common Stock) by the Company or the termination of such
      transaction. Notwithstanding the foregoing, the Purchaser shall have no
      right of first refusal with regard to any financing provided solely by an
      officer or director of the Company or any shareholder rights plan approved
      by the Board of Directors.

            other date as the parties may agree (the "Closing Date"), the

            occur (the "Closing").

                        of the maximum number of Warrant Shares for which the
                        Warrant may be exercised multiplied by the current per
                        share exercise price, by wire transfer of immediately
                        available funds to an account as specified in writing by

            waiver, by the party against whom enforcement of any such waiver is

      7.5.  Agreement Controls. If any topic is addressed both in the Purchase
            Agreement (or any document related thereto) and in this Agreement,
            this Agreement shall control.

      7.6.  Construction. The headings herein are for convenience only, do not
            constitute a part of this Agreement and shall not be deemed to limit
            or affect any of the provisions hereof. The language used in this
            Agreement will be deemed to be the language chosen by the parties to
            express their mutual intent, and no rules of strict construction
            will be applied against any party.

            counterparts, all of which when taken together shall be considered

            other party, it being understood that both parties need not sign the
            same counterpart.

      7.10. Severability. If any provision of this Agreement is held to be
            invalid or unenforceable in any respect, the validity and
            enforceability of the remaining terms and provisions of this
            Agreement shall not in any way be affected or impaired thereby and
            the parties will attempt to agree upon a valid and enforceable
            provision that is a reasonable substitute therefor, and upon so
            agreeing, shall incorporate such substitute provision in this
            Agreement.
