EXHIBIT 10.11.3

                                LEASE AMENDMENT
                              (12520 Grant Drive)

This Lease Amendment, dated as of July 1, 1999, is by and between 12520 Grant
Drive, LLC, a Colorado limited liability company ("Landlord") and Hi-Tech
Manufacturing, Inc. ("Tenant").

                                    RECITALS

A.   Landlord's predecessor, HTM Building Investors, LLC, and Tenant entered
into the Revised Lease Agreement, dated January 14, 1994, as amended on April 1,
1998 (the "Lease").

B.   Landlord and Tenant desire to modify the Lease as set forth below.

                                   AGREEMENT

Now, therefore, for good and valuable consideration, the receipt and sufficiency
of which is hereby acknowledged, the parties hereto agree as follows:

1.   The term of the Lease shall be extended to July 1, 2004.

2.   The Base Rent payable monthly under the Lease shall be:  $44,650.00 from
     July 1, 1999 to June 30, 2001; $46,436.00 from July 1, 2001 to June 30,
     2002; $48,293.00 from July 1, 2002 to June 30, 2003; and $50,225.00 from
     July 1, 2003 to June 30, 2004.

3.   In Section 8 of the Lease, the second sentence shall be amended to read,
     "Tenant further agrees to return the leased premises at the end of the term
     to Landlord in as good condition as when received, normal wear and tear
     excepted."

4.   Section 23 of the Lease is deleted.

5.   Landlord agrees to resurface the parking lot that is part of the leased
     premises. Immediately upon the completion of the parking lot resurfacing,
     to Landlord's satisfaction, Tenant agrees to reimburse Landlord $30,000 for
     the cost of such work.

Except as modified herein all of the terms and conditions of the Lease shall
remain unchanged and in full force and effect.

<PAGE>

     and administration with respect to the Plan, Awards, and Award Agreements

     and its determinations shall be final and binding upon all parties.

(b)  The Committee may delegate its authority under subsection (a), above, to
     persons other than its members to the extent it deems such action

     or other hypothetical investments.

(d)  The Committee may not at any time adjust the purchase price, Grant Price,
     or Market Price specified by Section 3 hereof (except for adjustments
     pursuant to Section 13 hereof).

6.   TYPES OF AWARDS

     The types of Awards described in subsections (a) through (d), below, may be
     granted or payable under the Plan, singly or in combination or in tandem
     with other Awards (or with awards under other plans of the Company or a
     Related Entity), as the Committee may determine. All Awards shall be in a
     form determined by the Committee. No Award shall be inconsistent with the
     terms of the Plan or fail to satisfy the requirements of applicable law.

     The Committee may, from time to time, grant dividend equivalents in respect
     of Awards.

(a)  Stock Options
     -------------

     A stock option represents the right to purchase a specified number of
     Shares, at a fixed Grant Price, during a specified term as the Committee
     may determine. The term of a stock option shall not exceed ten years from
     the date as of which the Grant Price is determined.

     The Grant Price shall be payable, at the discretion of the Committee, by
     the payment of cash, the delivery of Shares, and/or any other means that

--------------------------------------------------------------------------------
Genuity Inc. 2000 Long-Term Stock Incentive Plan                          Page 3
<PAGE>

     the Committee determines to be consistent with the Plan's purposes and
     applicable law.

     The stock options that may be granted under the Plan include (but are not
     limited to) incentive stock options that comply with the requirements of
     Section 422(b) of the Code. Incentive stock options may not be granted
     under the Plan after February 1, 2010. Incentive stock options may be
     granted only to Employees who are employed by the Company or by a
     subsidiary corporation (within the meaning of Section 424(f) of the Code),
     including a subsidiary corporation that becomes such after the adoption of
     the Plan.

     The Committee also may grant a right to purchase additional Shares to a
     Participant contingent upon the surrender of Shares owned by the
     Participant in payment of the Grant Price of a stock option granted under
     the Plan or upon the surrender of Shares by the Participant in payment of
     withholding tax liability with respect to such a stock option.

     The Grant Price of the initial stock options granted to Participants who
     were employees of the Company on or before the effective date of the
     Company's initial public offering, shall be the initial public offering
     price per Share. All other stock options granted under the Plan shall be
     exercisable at the Grant Price.

(b)  Stock Appreciation Rights
     -------------------------

     A stock appreciation right represents the right, denominated in Shares, to
     receive, upon surrender of the right (or of both the right and a related
     option in the case of a tandem right), in whole or in part, but without
     payment, an amount (payable in accordance with Section 9 hereof) that does
     not exceed the excess of the Market Price over the Grant Price for the
     number of Shares for which the stock appreciation right is exercised. The
     term of a stock appreciation right shall not exceed ten years from the date
     as of which the Grant Price is determined.

(c)  Performance Bonuses
     -------------------

     The Committee may, from time to time, grant Performance Bonuses to
     Participants in accordance with such terms and conditions that the
     Committee in its sole discretion may establish. Any such Performance
     Bonuses shall be payable in the form of Shares only (except for cash in
     lieu of fractional shares).

(d)  Other Stock-Based Awards
     ------------------------

     The Committee may, from time to time, grant Awards (other than the Awards
     described above) under the Plan that consist of or are denominated in or
     payable in, valued in whole or in part by reference to, or otherwise based
     on or related to, Shares. These Awards may include Shares and/or
     hypothetical Shares.

     The Committee may subject these Awards to restrictions on transfer and/or
     other restrictions on incidents of ownership as the Committee may
     determine.

     The Committee may grant Awards under this Section 6(d) that do not require
     the payment of additional consideration by the Participant (other than
     services previously rendered or, as may be permitted by applicable law,
     services to be rendered), either on the date of grant or the date any
     restriction(s) thereon are removed.

     The term of an Award that grants a Participant the right to purchase Shares
     shall not exceed ten years from the date as of which the purchase price is
     determined.

7.   LIMITATIONS ON AWARDS

     (a)  No Participant shall be granted options to purchase more than two
          million Shares in one calendar year.

     (b)  Except as provided in subsection (c), below, a Participant shall
          receive only one Award grant during the period beginning on the
          effective date of the Plan and ending four years after the effective
          date of the Plan.

     (c)  A Participant may receive a grant of an Award under the Plan at any
          time to the extent that such grant is consistent with a promotion or
          other significant increase in responsibility or, in the discretion of
          the Committee, necessary to ensure that the Awards granted to such
          Participant are appropriate in comparison to the Awards granted to
          other Participants.

     (d)  No Award shall be assignable or transferable other than by will or by
          the laws of descent and distribution. During the Participant's
          lifetime, an Award may be exercised only by the Participant or by the
          Participant's guardian or legal representative.

8.   AWARD AGREEMENTS

     An Award may be evidenced by an Award Agreement, the terms of which have
     been approved by the Committee, setting forth the terms and conditions
     applicable to the Award, including

     (a)  terms and conditions governing the extent (if any) to which the Award
          may vest, become exercised, be exercised or paid, or be canceled or
          forfeited,

     (b)  terms and conditions governing the disposition of the Award in the
          event of disability, death, or other termination of a Participant's
          employment,

     (c)  a provision that a Participant shall have no rights as a shareholder
          with respect to any Shares covered by an Award until the date on which
          the Participant or his nominee becomes the holder of record of such
          Shares, and

     (d)  terms and conditions governing tax withholding.

9.   PAYMENT OF AWARDS

     (a)  All payments of Awards shall be made on a date prescribed by the
          Committee, unless the Participant has elected to defer payment in
          accordance with the rules and regulations established by the
          Committee.

     (b)  At the discretion of the Committee, a Participant may be offered an
          election to substitute an Award for another Award or Awards of the
          same or different type.

     (c)  No fractional Shares shall be issued in connection with Awards under
          the Plan. The Committee shall determine whether cash, other
          securities, or other property shall be paid or transferred in lieu of
          fractional Shares, or whether fractional Shares or any rights thereto
          shall be canceled, terminated, or otherwise eliminated.

     (d)  Except as provided in subsection (c), above, payments of Awards shall
          be wholly in Shares. The Committee, in its sole discretion, shall
          determine whether the Shares shall be subject to restrictions on
          transfer and/or provisions regarding forfeiture of said Shares.

10.  REVOCATION OR AMENDMENT OF AWARDS

     (a)  Subject to any early termination restrictions imposed by the Committee
          in an Award Agreement and except as provided in subsection (b), below,
          the Committee may not, without the written consent of the Participant,
          revoke

--------------------------------------------------------------------------------

          an Award Agreement, and may not without such written consent make or
          change any determination or change any term, condition, or provision
          affecting an Award if the determination or change would adversely
          affect the Award or a Participant's rights thereto.

     (b)  The Committee may at any time and in any manner modify the terms of an
          Award that relate to the early termination of the option or Award
          period after the Participant's termination of employment; provided
          that such modification shall not apply to an Award to the extent that
          it has been previously exercised.

11.  LIMITATION ON NUMBER OF SHARES

     (a)  The aggregate number of Shares that may be subject to all Awards shall
          not exceed:

          (1)  Five percent of the outstanding Shares at the time of the initial
               public offering of the Shares for all individuals who were
               Employees on or before April 6, 2000, in the aggregate (except
               for Awards granted pursuant to Section 7(c) hereof;

          (2)  One percent of the outstanding Shares at the time of the initial
               public offering of the Shares for all individuals who first
               become Employees after April 6, 2000, and on or before January 6,
               2001, in the aggregate (except for Awards granted pursuant to
               Section 7(c) hereof); and

          (3)  Three percent of the outstanding Shares at the time of the
               initial public offering of the Shares plus any Shares that are
               forfeited by a Participant or that are part of an Award that
               expires unexercised for Awards granted pursuant to Section 7(c)
               hereof and for all individuals who first become Employees after
               January 6, 2001, in the aggregate.

     (b)  Subject to the limits imposed by subsection (a), above, no more than
          50,000,000 Shares shall be available to be issued pursuant to
          incentive stock options (within the meaning of Section 422(b) of the
          Code or any successor thereto).

12.  AMENDMENT OR TERMINATION OF THE PLAN

     The Board may, from time to time, alter, amend, suspend or terminate the
     Plan as it shall deem advisable, subject to any requirement for shareholder
     approval imposed by applicable law.  The termination of the Plan shall not
     cause any previously granted Awards to terminate.  After the termination of
     the Plan, any

--------------------------------------------------------------------------------
Genuity Inc. 2000 Long-Term Stock Incentive Plan                          Page 7
<PAGE>

     previously granted Awards shall remain in effect and shall continue to be
     governed by the terms of the Plan, the Awards, and any applicable Award
     Agreements. This Section applies regardless of whether the termination of
     the Plan occurs pursuant to Section 2 hereof or pursuant to this Section
     12.

13.  ADJUSTMENT PROVISIONS

     If the Committee determines that any dividend or other distribution
     (whether in the form of cash, Shares, other securities, or other property),
     extraordinary cash dividend, recapitalization, stock split, reverse stock
     split, reorganization, merger, consolidation, split-up, spin-off,
     combination, repurchase, or exchange of Shares or other securities, the
     issuance of warrants or other rights to purchase Shares or other
     securities, or other similar corporate transaction or event affects the
     Shares with respect to which Awards have been or may be issued under the
     Plan and that an adjustment is appropriate in order to prevent dilution or
     enlargement of the benefits or potential benefits intended to be made
     available under the Plan, then the Committee shall, in a manner that the
     Committee deems appropriate to prevent such dilution or enlargement, adjust
     any or all of

     (a)  the number and type of securities that thereafter may be issued under
          the Plan,

     (b)  the number and type of securities subject to outstanding Awards, and

     (c)  the Grant Price, purchase price, or Market Price with respect to any
          Award, or, if deemed appropriate, make provision for a cash payment to
          the holder of an outstanding Award.

     However, no adjustment shall be authorized with respect to incentive stock
     options to the extent that the adjustment would cause the options to
     violate Section 422(b) of the Code or any successor provision.  In
     addition, the number of securities subject to any Award denominated in
     Shares shall always be a whole number.

     In the event of an acquisition by the Company by means of a merger,
     consolidation, acquisition of property or stock, reorganization or
     otherwise, the Committee shall be authorized to cause the Company to issue
     or to assume stock options or stock appreciation rights, whether or not in
     a transaction to which Section 424(a) of the Code applies, by means of
     substitution of new options or rights for previously issued options or
     rights or an assumption of previously issued options or rights, but only if
     and to the extent that the substitution or assumption is consistent with
     the other provisions of the Plan and with any applicable law.

--------------------------------------------------------------------------------
Genuity Inc. 2000 Long-Term Stock Incentive Plan                          Page 8
<PAGE>

     Subject to any required action by the Company's shareholders, if the
     Company is a party to any merger or consolidation, a Participant holding an
     outstanding Award valued directly or indirectly by Shares shall be entitled
     to receive, upon the exercise of the Award, the same per Share
     consideration on the same terms that a holder of the same number of Shares
     that are subject to the Award would be entitled to receive pursuant to the
     merger or consolidation.

14.  NO REQUIRED SEGREGATION OF ASSETS

     Neither the Company nor any Related Entity shall be required to segregate
     any assets that may at any time be represented by Awards pursuant to the
     Plan.

15.  COSTS

     The Committee may require a Participant or beneficiary to bear all or part
     of the cost of exercising an Award or issuing Shares under the Plan.

16.  RIGHT OF DISCHARGE RESERVED

     Neither the Plan nor any Award or Award Agreement shall guarantee any
     Employee continued employment with the Company or a Related Entity or
     guarantee the grant of future Awards.  Either the Company or the Employee
     may terminate the employment relationship at any time and for any reason.

17.  NATURE OF PAYMENTS

     All Awards made pursuant to the Plan are in consideration of services for
     the Company or the Related Entities. Any gain realized pursuant to Awards
     under the Plan constitutes a special incentive payment to the Participant
     and shall not be taken into account as compensation for purposes of any of
     the employee benefit plans of the Company or any Related Entity except as
     may be determined by the Board or by the board of directors of the
     applicable Related Entity.

18.  SEVERABILITY

     If any provision of the Plan shall be held unlawful or otherwise invalid or
     unenforceable in whole or in part, the unlawfulness, invalidity, or
     unenforceability shall not affect any other provision of the Plan or part
     thereof, each of which shall remain in full force and effect.

19.  GOVERNING LAW

     To the extent not preempted by federal law, the provisions of the Plan will
     be construed and enforced in accordance with the laws of the Commonwealth
     of Massachusetts, excluding any conflicts or choice of law rule or
     principle that might otherwise refer construction or interpretation of this
     provision to the substantive law of another jurisdiction, except that
     issues regarding the rights attendant to stock ownership shall be governed
     by the laws of the State of Delaware (excluding its conflicts or choice of
     law rules or principles) and construed accordingly.
