24b-2 under the Securities Act of 1934, as amended. The omitted portion has been

Notwithstanding the above, Unilens may take such deduction under the following
conditions: 1) Unilens provides written notice of any disputed amount within
seven (7) days of the date a shipment is delivered; and 2) the parties are
unable to reach resolution of the disputed amount within twenty-one (21) days
after the date B&L receives such notice. However, nothing herein shall preclude
the parties from exercising any of their legal remedies for redress of disputes,
including but not limited to termination for breach.

                             AGREEMENT FOR PURCHASE
                               AND SALE OF ASSETS

     This agreement is entered into on the 1/st/ day of March, 2000, by and
between Biocompatibles Eyecare, Inc., a corporation organized under the laws of
Delaware, with its principal office located at 1215 Boissevain Avenue, Norfolk,
VA, 23507, hereafter referred to as "Seller", and Unilens Corp. USA, a
corporation organized under the laws of Delaware, with its principal offices
located at 10431 72/nd/ Street North, Largo, Florida, 33777, hereafter referred
to as "Buyer".

     In consideration of the mutual covenants of the parties, Seller and Buyer
agree:

1.   Sale of Business

     a.    Seller shall sell, assign, and deliver to Buyer and Buyer shall
purchase and accept, on the closing date, all of Seller's right, title and
interest in and to:

     i.    Finished Goods Inventory - On or before the Closing Date, Seller will
           deliver on a consignment basis to Buyer, as consignee, all salable
           finished goods inventory for the products described on Exhibit A
           (hereinafter the "Inventory"). Delivery of the Inventory shall be at
           the expense of both parties shared equally. Upon delivery by Seller,
           Buyer shall have the exclusive right and shall thereafter use its
           best efforts to sell all such Inventory as quickly as is commercially
           reasonable and practicable. Title of the Inventory shall remain with
           Seller until such products are sold by Buyer. Seller authorizes and
           consents to the transfer of title to the Inventory upon its sale by
           Buyer. During the period from the Closing Date (as defined herein)
           until the date one year from the Closing Date, and subject to the
           provisions of Section 2 below, Buyer will pay Seller on a quarterly
           basis for Inventory sold, with such payment to be at the rate of
           fifty percent (50%) of Seller's current average realized price (as
           defined herein) for all Inventory sold during the pertinent quarter,
           after first deducting the royalty payments described in Section 1
           (a)(ii) below. For any Inventory sold after one (1) year after the
           Closing Date but before the end of two years from the Closing Date
           and subject to the provisions of Section 2 below, Buyer will pay
           Seller on a quarterly basis for Inventory sold with such payment to
           be at the rate of sixty percent (60%) of the current average realized
           price (as defined herein) for all Inventory sold during the pertinent
           quarter after first deducting the royalty payments described in
           Section l(a)(ii) below. Inventory will be sold by Buyer on a FIFO
           basis. The total amount to be paid to Seller for Inventory sold in
           year two as described in this subparagraph 1 (a)(i) shall be in all
           events capped at and in no event shall exceed one hundred thousand
           dollars ($100,000.00). At the earlier of the end of two years from
           the Closing Date or the payment to Seller of one hundred thousand
           dollars ($100,000.00) for inventory sold during the second year after
           the Closing Date, the Inventory will become the property of Buyer
           with no additional payment due from Buyer to Seller for said
           Inventory. For any quarterly payments to be made under this Section
           l(a)(i) and subject to the provisions of Section 2 below,

<PAGE>

           payment shall be delivered to Seller within thirty (30) days from the
           end of each applicable calendar quarter. Seller's continuing interest
           in the Inventory during the two years from the Closing Date will be
           perfected by filing UCC-1's with the Florida Secretary of State.
           Buyer agrees that the Inventory shall be maintained at Buyer's
           location in Florida. In the event Buyer transfers the location of the
           Inventory such that it is maintained in a state other than Florida,
           Buyer shall prepare, execute and file a UCC-1 in that state
           acceptable to Seller, as needed to perfect Seller's security or other
           interest in the Inventory. The parties acknowledge that they intend
           for the Inventory to include a twelve months supplyof Soft55EW
           lenses. If after the Closing Date it is discovered between the
           parties that the Inventory does not include said twelve months supply
           (with said twelve months supply to be determined based upon the
           Soft55EW lenses sold by Seller during the twelve month period
           immediately preceding the Closing Date), then Seller shall provide on
           the same consignment basis additional Soft55EW lenses to reach the
           twelve months supply.

     ii.   Inventory Under the CIBA Agreement. Buyer and Seller acknowledge that
           portions of the Inventory to be delivered to Buyer under consignment
           as described in Section l(a)(i) above are subject to an Agreement,
           dated December 2, 1994, between CIBA Vision Corporation (hereinafter
           "CIBA") and Seller, a true and complete copy of which Agreement with
           CIBA is attached hereto for reference as Exhibit B (hereinafter the
           "CIBA Agreement"). Although Buyer is not assuming or agreeing to be
           liable for the entire CIBA Agreement hereunder, Buyer acknowledges
           and agrees to try to reach an agreement with CIBA relating to royalty
           payments and consigned Inventory and under which new agreement with
           CIBA Seller would not continue to be obligated to CIBA under the CIBA
           Agreement after the date of the new agreement between CIBA and Buyer.
           Although Buyer agrees to use its best efforts to reach such an
           agreement with CIBA, Buyer makes no warranty to Seller that it will
           be able to reach such an agreement with CIBA. Unless and until Buyer
           is able to reach such a separate agreement with CIBA, Seller and
           Buyer agree as follows as to payment of royalties under the CIBA
           Agreement. First, Seller shall be responsible to pay any and all
           outstanding royalties under the CIBA Agreement accruing prior to the
           Closing Date without any portion of the funds in payment thereof
           being paid by Buyer. Second, until the earlier of the date on which
           the CIBA Agreement terminates or the date on which Buyer reaches an
           agreement with CIBA regarding the royalty payments and consigned
           Inventory which releases Seller from all obligations under the CIBA
           Agreement, Buyer shall pay directly to CIBA all royalties owed to
           CIBA under the CIBA Agreement as a result of sales made by Buyer
           during the aforesaid period and fulfill all obligations under the
           CIBA Agreement relating to such payments or the Products to which
           such payments relate (including but not limited to such obligations
           under Sections 5.1, 7.2, 7.3, 7.4, 8.2 and 8.3 of the CIBA
           Agreement). Notwithstanding anything to the contrary set forth above,
           the amounts paid by Buyer to Seller under Section 1 (a)(i) above will
           be determined by first reducing the current average realized price by
           the amount of royalty payments required to be made by Buyer to CIBA
           under

                                        2

<PAGE>

           the CIBA Agreement or, if applicable, under Buyer's agreement with
           CIBA (so long as said royalty payments do not exceed the rate of
           those required under the CIBA Agreement; if the royalty payments do
           exceed those required under the CIBA Agreement, the maximum reduction
           for royalty payments applicable to Seller shall be the applicable
           rates under the CIBA Agreement).After deducting the royalty payments
           from the current average realized price, then the percentage division
           of the remainder shall be applied as set forth in Section 1 (a)(i)
           above. By way of example only, if during the first year after the
           Closing Date, Buyer reaches an agreement with CIBA regarding royalty
           payments and consigned Inventory, Buyer will pay Seller on a
           quarterly basis at the rate of fifty percent (50%) of Seller's
           current average realized price (as defined herein) for all Inventory
           sold during the pertinent quarter after first deducting from such
           price on an item by item basis the amount of any royalties paid to
           CIBA by Buyer under Buyer's new agreement with CIBA, or the
           applicable royalty under the CIBA Agreement, whichever is less.

     iii.  Softcon EW Inventory. Buyer and Seller acknowledge and agree that
           certain Softcon EW inventory provided by CIBA to Seller pursuant to
           the CIBA Agreement described in Section l(a)(ii) above (hereinafter
           the "CIBA Inventory") belongs to CIBA rather than Seller and is not
           part of the Inventory. Buyer agrees that Buyer will take
           responsibility for making arrangements with CIBA regarding transfer
           of such CIBA Inventory to Buyer and its customers and agrees to be
           directly responsible to CIBA for all obligations of Seller arising
           after the Closing Date with respect to the CIBA Inventory under the
           CIBA Agreement. Buyer will be responsible for any payment directly to
           CIBA on the CIBA Inventory and Buyer shall not be obligated under
           this Agreement or otherwise to make any payments to Seller for sale
           of the CIBA Inventory.

     iv.   Raw Materials/Small Equipment/Supplies. Seller will transfer to Buyer
           all raw materials and supplies (including lot and material acceptance
           specifications) associated with the products listed on Exhibit A,
           including without limitation any raw materials and supplies listed on
           Exhibit C, in inventory on or before the Closing Date (hereinafter
           the "Raw Materials"). Subject to the terms of Section 2 below, Buyer
           shall pay Seller for the CIBA buttons at the rate of (eighty-one
           cents per unit ($.81) and for the LL38 molds at the rate of
           eighty-nine cents per unit ($.89). Fifty percent (50%) of the amount
           due will be paid 30 days after Buyer receives 510K approvals or
           completion of all actions necessary for transfer of existing 510K's,
           whichever is applicable, to transfer the 510K's to Buyer, for
           products listed on Exhibit F manufactured utilizing Vifilcon or
           Tefilcom materials, with the balance payable one hundred eighty (180)
           days after receipt by Buyer of such above-referenced 51 OK approvals,
           or completion of all actions necessary for transfer of existing
           510K's, whichever is applicable, to transfer the 510K's to Buyer.
           Buyer agrees to exercise its best efforts in applying for and seeking
           to obtain the 510K approval or transfer from the FDA in connection
           with the Raw Materials, and in all events to submit any notices or
           other documents needed to apply therefor to the FDA not more than 60
           days after the Closing Date.

                                        3

<PAGE>

           To the extent necessary, Seller will cooperate in the process for
           such approvals or transfers. If FDA 510K approvals or transfers are
           withheld or denied for any reasons outside of Buyer's control, no
           payment for Raw Materials will be made to Seller. Buyer shall give
           Seller a purchase money security interest in the Raw Materials, which
           security interest will be perfected by execution and delivery of a
           security agreement substantially in the form attached hereto as
           Exhibit D , and through the filing of UCC-ls with the Florida
           Secretary of State. Buyer agrees that the Raw Materials shall be
           maintained at Buyer's location in Florida. In the event Buyer
           transfers the location of the Raw Materials such that it is
           maintained in a state other than Florida, Buyer shall prepare,
           execute and file a UCC-1 in that state acceptable to Seller, as
           needed to perfect Seller's security interest in the Raw Materials.

     v.    Accounts Receivable - For a period of thirty days from the Closing
           Date, Seller shall continue collecting accounts receivable derived
           from the sale of the line of products listed on Exhibit A attached
           hereto (the "Accounts Receivable") and will forward copies of checks,
           supporting documents, and remittance advices to Buyer for posting to
           customer accounts for a period of thirty (30) days from the Closing
           Date. Seller shall keep ninety-eight percent (98%) of proceeds from
           the Accounts Receivable received by Seller during this thirty day
           period after the Closing Date. Seller shall remit to Buyer the amount
           of two percent (2%) of the proceeds from the Accounts Receivable
           collected by Seller during the thirty day period after the Closing
           Date. As of the date which is thirty (30) days after the Closing
           Date, al Accounts Receivable of Seller not collected will be
           transferred to Buyer. In connection therewith, Seller will execute
           any documents necessary to accomplish such transfer of Accounts
           Receivable and will provide documentation such as billing files
           necessary for Buyer's collection efforts with regard to the remaining
           Accounts Receivable. Buyer will pay Seller at the rate of ninety
           percent (90%) of the balance (net of returns and discounts) for
           amounts collected by Buyer for a period of twelve (12) months from
           the Closing Date. Subsequent to the thirty day period after the
           Closing Date, Buyer shall collect the Accounts Receivable and shall
           pay to Seller the amounts described herein. Buyer shall exercise best
           efforts to collect Accounts Receivable (including credit holds,
           collection letters, third party collection letters and collection
           agencies) as quickly as commercially reasonable and practicable. All
           amounts due to be paid to the other party under this subparagraph v
           shall be paid within thirty (30) days from their collection. Upon
           reasonable request, Seller and Buyer shall account to one another
           (including providing reasonable documentation) for collection of
           Accounts Receivable by the respective parties during the time periods
           described herein. Buyer shall give the Seller a purchase money
           security interest in such Accounts Receivable (other than those to be
           collected during the first thirty (30) days from the Closing Date),
           which will be perfected by execution and delivery of a security
           agreement substantially in the form attached hereto as Exhibit D and

           this subparagraph, the security interest shall be given on an amount
           agreed to be twenty-five percent (25%) of the Accounts Receivable at
           the Closing Date. Buyer agrees that the books and records

           in Florida. In the event Buyer transfers the location of the books
           and records for the Accounts Receivable such that it is maintained in
           a state other than Florida, Buyer shall prepare, execute and file a
           UCC-1 in that state acceptable to Seller, as needed to perfect
           Seller's security interest in the Accounts Receivable.

           (hereinafter the "Equipment") will be transferred to Buyer on the

           Seller a purchase money security interest in the Equipment, which
           security interest will be perfected by execution and delivery of a
           security agreement substantially in the form shown on Exhibit E
           attached hereto, and filing a UCC-1 with the Florida Secretary of

           Seller in payment of any unpaid amounts owed for Equipment under this
           Agreement. Buyer agrees that the Equipment shall be maintained at
           Buyer's location in Florida. In the event Buyer transfers the
           location of the Equipment such that it is maintained in a state other
           than Florida, Buyer shall prepare, execute and file a UCC-1 in that

           transfer documents as Buyer may reasonably request to effect the
