                     MODIFICATION AND SETTLEMENT AGREEMENT

          MODIFICATION AND SETTLEMENT AGREEMENT, dated as of June 12, 2000,
among Advanced Optics Electronics, Inc., a Nevada corporation (the "Company"),
and the Purchasers listed on Schedule I attached hereto (each a "Purchaser" and
collectively, the "Purchasers").

                                   RECITALS:

         WHEREAS, the Company sold and issued issued to the Purchasers, and the
Purchasers purchased from the Company, $500,000 aggregate principal amount of
the Company's 8% Convertible Notes due June 3, 2001 ("Convertible Notes"),
pursuant to a Securities Subscription Agreement dated as of June 3, 1999
("Agreement"); and

         WHEREAS, pursuant to the terms of the Agreement and the Convertible
Notes, the Convertible Notes are convertible into shares of the Company's
common stock, par value $.001 per share ("Common Stock"); and

         WHEREAS, pursuant to the terms of the Agreement, the Company issued to
the Purchasers warrants to purchase an aggregate of 12,500,000 shares of Common
Stock ("Warrants"); and

         WHEREAS, pursuant to the Agreement, and a certain Registration Rights
Agreement, dated as of June 3, 1999 ("Registration Rights Agreement"), the
Purchasers were granted certain registration rights with respect to shares of
Common Stock issuable (i) as interest under, and upon conversion of, the
Convertible Notes, and (ii) upon exercise of the Warrants; and

         WHEREAS, the Company wishes to modify the Agreement, the Convertible
Notes and Registration Rights Agreement in order to fully and finally settle
its obligations to the Purchasers, and the Purchasers are willing to effectuate
a settlement with the Company upon the terms and conditions set forth in the
Modification and Settlement Agreement ("Modification Agreement").

         NOW, THEREFORE, in consideration of the foregoing premises and the
covenants contained herein and other good and valuable consideration, the
receipt and sufficiency of which are hereby acknowledged, the parties hereto
hereby agree as follows:

         1.  Conversion of Convertible Notes and Settlement of Warrants.

         (a) Simultaneously with the execution of this Modification Agreement,
the Purchasers shall issue Notices of Conversion of the Convertible Notes and
the Company shall issue to the Purchasers, in denominations set forth on
Schedule I, 2,000,000 shares of the Company's common stock in accordance with
the Notices of Conversion ("Conversion Shares"). The Conversion Shares shall be
issued pursuant to Rule 144 with a holding period commencing on June 3, 1999
("Holding Period"). The Purchasers shall be entitled to sell the Conversion
Shares in accordance with Rule 144 based on the Holding Period. An opinion of
counsel with regard to the saleability of the Conversion Shares shall be
provided by the Purchasers. Sale of the Conversion Shares shall return to the




   2

Purchasers an aggregate of USD$ 1,000,000 net of all sales commissions and any
other costs of sale and administration ("Return"). In the event that the sale
of (i) less than all Conversion Shares aggregates the full Return, the balance
of the Conversion Shares shall be returned to the Company; or (ii) all of the
Conversion Shares aggregates less than the full Return, then the Company, upon
demand made by the Purchasers in writing ("Demand Notice"), shall deliver to
the Escrow Agent, as defined below, on as many occasions as necessary to
effectuate the purposes of this Section 1(a), tranches of 500,000 Conversion
Shares ("Share Tranche or Share Tranches") until sales of the Conversion Shares
aggregate the full Return. A Demand may be made on as many occasions as
necessary to effectuate the purposes of this Section 1(a). In the event that
the sale of less than the full number of shares in any Share Tranche results in
the Purchasers achieving the full Return, then the balance of the Share Tranche
shall be returned to the Company.

         (b) Simultaneously with the execution of this Modification Agreement,
the Purchasers shall issue Notices of Conversion of the Convertible Notes and
the Company shall issue to the Purchasers, in denominations set forth on
Schedule I, 7,200,000 shares of the Company's common stock in accordance with
the Notices of Conversion ("Other Conversion Shares"). The Other Conversion
Shares shall be issued pursuant to Rule 144 with a holding period commencing on
June 3, 1999 ("Holding Period"). The Purchasers shall be entitled to sell the
Other Conversion Shares in accordance with Rule 144 based on the Holding
Period. An opinion of counsel with regard to the saleability of the Other
Conversion Shares shall be provided by the Purchasers.

         (c) The Conversion Shares and any shares from Share Tranches, shall be
deposited in an account ("Share Escrow Account") maintained by Edward H.
Burnbaum, Esq. ("Escrow Agent") and shall be sold out of such Share Escrow
Account for the benefit of the Purchaser. The Company shall receive duplicate
confirmations of all sales made from the Share Escrow Account. Proceeds from
the sale of Conversion Shares or Share Tranches shall be payable from the
Escrow Account to the Purchaser as realized. The Conversion Shares or Share
Tranches may be sold each trading day on an amount which does not exceed the
greater of (i) an aggregate value of $20,000 based upon the bid price on the
trading day the stock is sold of the Company's common stock as reported on the
OTC Electronic Bulletin Board, or any exchange on which the Company's shares
are then trading, for each individual Purchaser, or (ii) 20% of the daily
trading volume on the trading day on which the stock is sold for all
Purchasers. The Company, in its sole discretion, may permit the Purchasers to
sell Conversion Shares at greater amounts than as set forth in this Section
1(c)(i) and (ii) on any trading day or days.

         (d) Upon performance by the Company of its obligations under this
Modification Agreement, the Purchasers shall deliver to the Company, along with
any Conversion Shares or shares from a Share Tranche, as the case may be, that
remain after the full Return has been achieved, the Convertible Notes and the
Warrant. In the event, for any reason, the Company fails to perform its
obligations under this Agreement, the Purchasers shall retain the Convertible
Notes and the Warrants, and may enforce same in accordance with their terms,
however, the Company shall be entitled to a credit against the shares
exercisable under the Warrants in the number of Conversion Shares and Share
Tranches actually delivered to the Purchasers.

         (e) For a period of 12 months from the date of this Modification
Agreement, the Company shall not take any action to forward or reverse split
its shares of common stock into a greater or smaller number of shares of common
stock, as the case may be.

         2. Resolution. Simultaneously with the execution of this Agreement,
the Company shall deliver (i) to the Purchasers a Resolution, substantially in
the form annexed hereto as Exhibit A, authorizing the transaction contemplated
in this Modification Agreement, and (ii) to the Escrow Agent, a Resolution,
substantially in the form annexed hereto as Exhibit B ("Transfer Agent
Resolution"), instructing the Company's transfer agent, Oxford Transfer and
Registrar, 317 SW Alder, Suite 1120, Portland, Oregon 97204 ("Transfer Agent")
to issue to Purchasers shares of the Company's common stock registered in the
name of the Purchasers, in an amount equal up to $1,000,000, or at some lesser
amount as the Escrow Agent, in his sole discretion may direct the transfer
agent, and providing that the Company shall not change its transfer agent from
the Transfer Agent, without the express written consent and directive of the
Escrow Agent. The Transfer Agent Resolution may be delivered by the Escrow
Agent to the Transfer Agent in the event that, for any reason whatsoever, the
Company fails to perform its obligations under this Modification to deliver
Conversion Shares or Share Tranches, or in the event that the Company changes
or attempts to change its transfer agent from the Transfer Agent without the
express written consent of the Purchasers. Upon written demand from the
Purchasers, Escrow Agent shall deliver the Transfer Agent Resolution to the
Transfer Agent as provided in this Section 2. Escrow Agent shall be entitled to
honor any such written demand from the Purchasers and shall ignore any demand
or instructions to the contrary from the Company.

         3. Concerning the Escrow Agent. To induce the Escrow Agent to act
hereunder, it is further agreed by the undersigned that:

                  (a) This Escrow Agreement expressly sets forth all the duties
of the Escrow Agent with respect to any and all matters pertinent hereto. No
implied duties or obligations shall on the part of the Escrow Agent shall be
read into this Escrow Agreement. The Escrow Agent shall not be bound by the
provisions of any agreement among the other parties hereto except this Escrow
Agreement.

                  (b) The Escrow Agent shall not be liable for any action or
failure to act in its capacity as Escrow Agent hereunder unless such action or
failure to act shall constitute willful misconduct on the part of the Escrow
Agent, in which case there shall be no indemnification obligations.

                  (c) The Escrow Agent shall be entitled to rely upon any
order, judgment, certification, demand, notice, instrument or other writing
delivered to it hereunder without being required to determine the authenticity
or the correctness of any fact stated therein or the propriety or validity of
the service thereof. The Escrow Agent may act in reliance upon any instrument
or signature believed by it to be genuine and may assume, unless he has actual
knowledge to the contrary, that any person purporting to give notice or receipt
or advice or make any statement or



                                      -3-
   4


execute any document in connection with the provisions hereof has been duly
authorized to do so.

                  (d) The Escrow Agent may act pursuant to the advice of
counsel with respect to any matter relating to this Escrow Agreement and shall
not be liable for any action taken or omitted in accordance with such advice.

                  (e) The Escrow Agent does not have any interest in the
Conversion Shares, Share Tranches, Transfer Agent Resolution or any other
property deposited hereunder but is serving as escrow holder only and having
only possession thereof, and is not charged with any duty or responsibility to
determine the validity or enforceability of any such documents.

                  (f) The Escrow Agent (and any successor Escrow Agent) may at
any time resign as such by delivering the Transfer Agent Resolution and any
Conversion Shares or Tranche Shares in the Escrow Agent's account to any
successor Escrow Agent, jointly designated by the other parties hereto in
writing, or to any court of competent jurisdiction, whereupon the Escrow Agent
shall be discharged of and from any and all further obligations arising in
connection with this Escrow Agreement thereafter. The resignation of the Escrow
Agent will take effect on the earlier of (a) the appointment of a successor
(including a court of competent jurisdiction) or (b) the day which is 30 days
after the date of delivery of its written notice of resignation to the other
parties hereto. If at that time the Escrow Agent has not received a designation
of a successor Escrow Agent, the Escrow Agent's sole responsibility after that
time shall be to safekeep the Transfer Agent Resolution, the Conversion Shares
and the Tranche Shares and not make delivery or disposition thereof until
receipt of a designation of successor Escrow Agent or a joint written
disposition instruction by the other parties hereto or a final order of a court
of competent jurisdiction.

                  (g) In the event of any disagreement among the parties hereto
resulting in adverse claims or demands being made in connection with the
Transfer Agent Resolution, the Conversion Shares or the Tranche Shares, or in
the event that the Escrow Agent otherwise determines that the Transfer Agent
Resolution, the Conversion Shares or the Tranche Shares should be retained,
then the Escrow Agent may retain same until the Escrow Agent shall have
received (i) a final nonappealable order of a court of competent jurisdiction
directing delivery of the Transfer Agent Resolution, the Conversion Shares or
the Tranche Shares, or (ii) a written agreement executed by the other parties
hereto directing delivery of the same, in which case the Escrow Agent shall
promptly deliver the same in accordance with such order or agreement. Any court
order referred to in (i) above shall be accompanied by a legal opinion by
counsel for the presenting party reasonably satisfactory to the Escrow Agent to
the effect that said court order is final and nonappealable. The Escrow Agent
shall act on such court order and legal opinion without further question.

                  (h) This Escrow Agreement shall be binding upon and inure
solely to the benefit of the parties hereto an their respective successors
(including successors by way of merger) and assigns, heirs, administrators and
representatives and shall not be enforceable by or inure to the benefit of any
third party except as provided in paragraph (g) with respect to a resignation
by the Escrow Agent.

                  (i) Purchasers and the Company agree, jointly and severally
to indemnify, defend and hold harmless the Escrow Agent from and against any
and all costs (including, without limitation, legal fees and expenses),
liabilities, claims and losses arising out of or in connection with this
Modification Agreement or any action or failure to act by the Escrow Agent
under this Modification Agreement. This Modification Agreement may not be

hereunder shall be effective unless in a writing signed by the party to be
charged.
