        2.1.    LICENSE GRANT. Subject to the terms and conditions of this
Agreement, GEN-PROBE hereby grants SPECIALTY and SPECIALTY hereby accepts a
non-exclusive, non-transferable, royalty-bearing license under Patent Rights (i)
to practice Licensed Methods in the Field within SPECIALTY's and is Affiliates'
reference laboratories and (ii) to make, have made, use, and export Licensed
Products solely for use by SPECIALTY and its Affiliates, if any, in the practice
of Licensed Methods in the Field. License grant shall not include the right to
sell Licensed Product and/or Licensed Method to third parties.

        2.2.    GEN-PROBE RETAINED RIGHTS. GEN-PROBE shall retain the
unrestricted right to make, have made, use, sell or offer for sale and/or to

of this Agreement, inside or outside the Field. Except for the licenses
expressly granted under section 2.1, no right, title, or interest in any
discovery, invention or other technology, data or information (or any patent,
copyright, trademark, or other intellectual property rights therein) of
GEN-PROBE shall pass to SPECIALTY under this License. GEN-PROBE shall not be
under any obligation to grant to SPECIALTY any additional rights, other than
those granted by section 2.1, in any patent, copyright, trademark, or other
intellectual property, nor shall GEN-PROBE be restricted with respect thereto.

        2.3.    LIMITATION OF RIGHTS. SPECIALTY acknowledges that its rights
under Patent Rights are limited to those expressly granted herein and that
SPECIALTY is not granted the right to sell, transfer, or otherwise make
available to third parties Licensed Products and/or Licensed Methods for use

                               FEES AND ROYALTIES

        3.1.    PERCENTAGE ROYALTIES. SPECIALTY agrees to pay GEN-PROBE
royalties with respect to each and every Assay or Assay Series performed by
SPECIALTY or an Affiliate of SPECIALTY. The amount of royalties payable under
this Section 3.1 shall be determined on a Calendar Quarter basis and, for any
Calendar Quarter, such amount shall be calculated by taking the product of (A)
the Net Royalty Sales for such Calendar Quarter, multiplied by (B) the
Applicable Royalty Rate.

        3.2.    NET ROYALTY SALES. In any Calendar Quarter Net Royalty Sales
shall mean the aggregate amount of revenue in U.S. Dollars (converted as
necessary for sales made in a currency other than U.S. Dollars into U.S. Dollars
at the applicable Exchange Rate on the last business day of such Calendar
Quarter in accordance with Section 1.10 above) received or receivable by
SPECIALTY and its Affiliates in consideration of performance of an Assay or
Assay Series (including revenues received for services and materials) during
such Calendar Quarter. In the event an Assay Series is performed, the Net
Royalty Sales shall be calculated on the consideration received for the Assay
Series and not limited to a single assay within the series. The applicable
royalty rate shall be [***]* of the Net Royalty Sales. For any Assay or Assay
Series performed for consideration other than cash, the Net Royalty Sales shall
be deemed to be the average price charged by SPECIALTY or its Affiliates for the
performance of an identical Assay or Assay Series in such country during such
Calendar Quarter in "arms-length" transactions and only the total amount of all
excise taxes, sales taxes, value added taxes, consumption taxes, customs duties
and other taxes or duties (excluding income taxes or franchise taxes) imposed
with respect to any such sales.

        3.3.    REPORTS AND PAYMENTS.

                3.3.1.  ROYALTY REPORTS. Commencing with the First Commercial

                        d.      Total Net Royalty Sales in U.S. dollars for the
        applicable Royalty Period, together with the exchange rates used for
        conversion; and

                        e.      Calculation of the royalty amount payable to
        GEN-PROBE for the applicable Royalty Period.

All such reports shall be maintained in confidence by GEN-PROBE. If no royalties
or other payments are due to GEN-PROBE for any period, the report shall so
state.

                3.3.2.  ROYALTY PAYMENTS. Concurrent with these reports,
SPECIALTY shall remit to GEN-PROBE any payment due for the applicable Royalty
Period. The method of payment shall be by check or wire transfer as directed
from time to time by GEN-PROBE. All amounts payable to GEN-PROBE under this
Section will first be calculated in the currency of sale and then converted into
U.S. dollars in accordance with Section 1.10 and, to the extent permitted by
applicable law, such amounts shall be paid without any deduction for withholding
taxes, value-added taxes, or any other changes applicable to such payments.

        3.4.    PAYMENTS IN U.S. DOLLARS. All payments due under this Agreement
shall be payable in U.S. dollars. Conversion of foreign currency to U.S. dollars
shall be made in accordance with Section 1.10.

        3.5.    RECORDS. SPECIALTY shall keep, and shall require that its
Affiliates keep, for a period of not less than three (3) years after each
Calendar Year, complete, true and accurate books of account and other records
containing all information and data which may be necessary to ascertain and
verify the amount of royalties payable hereunder for such Calendar Year,
including, without limitation, detailed backup for the computations of Net
Royalty Sales which records shall contain sufficient information to permit
GEN-PROBE to confirm the accuracy of any reports delivered to GEN-PROBE in
accordance with Section 3.4. During the term of this agreement and for a period
of three (3) years thereafter, GEN-PROBE shall have the right from time to time
(not to exceed twice during each Calendar Year) to cause an independent
certified public accountant to inspect, in confidence, and audit all such books
and records at its expense, during normal business hours for the sole purpose of
verifying any reports and payments delivered under this Agreement and shall
provide SPECIALTY with a copy of any report given to GEN-PROBE. The parties
shall reconcile any underpayment or overpayment within thirty (30) days after
the accountant delivers the results of the audit. In the event that any audit
performed under this Section reveals an underpayment in excess of five percent
(5%) in any Royalty Period, SPECIALTY shall bear the full cost of such audit.

        3.6.    LATE PAYMENTS. Any payments by SPECIALTY that are not paid on or
before the date such payments are due under this Agreement shall bear interest,
to the extent permitted by law, at an annual rate of two percentage points above
the annual prime rate of interest most recently declared by Wells Fargo Bank (or
its successor), calculated based on the number of days that payment is
delinquent.

SPECIALTY, from time to time such portions of GEN-PROBE's technology as may be
mutually agreed between the parties.

        4.2.    PROSECUTION OF PATENT FILINGS BY GEN-PROBE. GEN-PROBE shall, at
its own expense, secure and maintain patents on modifications made during the
Term, if, in GEN-PROBE's sole discretion, it is an appropriate business decision
to do so. If GEN-PROBE elects not to file or maintain a patent on any
modification, it shall notify SPECIALTY of its decision in sufficient time to
allow SPECIALTY, in its discretion, to assume responsibility for such filing or
maintenance. In such event, GEN-PROBE shall receive a non-exclusive license to
practice under any patent obtained by SPECIALTY.

        4.3.    COOPERATION. SPECIALTY shall make available to GEN-PROBE, or its
authorized attorneys, agents or representatives, reasonable access to such of
its employees as GEN-PROBE may consider reasonably necessary to render
assistance in connection with GEN-PROBE's preparation and submission of patent
filings, and shall use its best efforts, at its sole cost and expense, to cause
any such employees to execute and deliver any and all documents as may be
necessary to evidence the right of GEN-PROBE to make such Patent filings.

        4.4.    INFRINGEMENT BY THIRD PARTIES.

                        (a)     If SPECIALTY becomes aware of any known or
suspected infringement by a third party on any patents or copyrights, or any
unauthorized use or misappropriation of know-how, Confidential Information or
other proprietary rights in any way pertaining to the Patent Rights, SPECIALTY
shall notify GEN-PROBE, in writing, within two (2) weeks of learning of such
infringement and shall provide all available supporting information known to
SPECIALTY regarding any such infringement, unauthorized use or misappropriation.

                        (b)     If GEN-PROBE, at its own expense, commences a
suit under this Section 4.5, SPECIALTY shall provide reasonable cooperation and
assistance to GEN-PROBE in connection with any such suit, without any charge
therefor other that reasonable out-of-pocket expenses.

                        (c)     In the event GEN-PROBE commences a suit under
Section 4.5, GEN-PROBE may require SPECIALTY to join in such suit as a party,
but SPECIALTY shall have no obligation to participate in the litigation except
to the extent action is required of a named party to the suit. If SPECIALTY is
required to join in any such suit, SPECIALTY shall have the right, at its sole
expense, to participate and be represented in any such suit by its own counsel,
which counsel shall be reasonably acceptable to GEN-PROBE.

        4.5.    ALLEGED INFRINGEMENT ON RIGHTS OF THIRD PARTIES. In the event
that any Third Party makes a written claim or demand, or brings an action, suit
or proceeding against either Party (or any of its Affiliates), alleging
infringement of such third party's patent rights or copyrights or unauthorized
use or misappropriation of its know-how, Confidential Information or

                                       7

merits of any matter which is the subject of any such claim, demand, action,
suit or proceeding.

        days) to Disclosing Party to enable it to resist such disclosure.

                6.2.2.  The foregoing exceptions to Confidential Information
shall not operate to exclude from Confidential Information that which (i) is
merely embraced by more general information available on a nonconfidential basis
or, (ii) consists of a combination of features, each of which may be publicly
available, but wherein the combination itself and its principle of operation
constitute Confidential Information because they are not embraced by
corresponding information which is within one of the foregoing exceptions.

        Any controversy, claim or dispute existing out of or relating to this
Agreement, or the breach thereof, shall be resolved by binding arbitration in
San Diego County, State of California and any judgment upon the award rendered
by arbitration may be entered in any Court having jurisdiction. If arbitration

arbitrator. If the Parties are unable to agree on an arbitrator, then they will
obtain nominations of three potential arbitrators from Judicial Arbitration and
Mediation Services ("JAMS") and each party will have the right to strike one
candidate's name from the list. JAMS will then designate the arbitrator. Any
arbitration award shall also include, but shall not be limited to, any and all
court or arbitration costs, attorney fees and any other costs or charges
reasonably necessary to adjudicate the controversy, in addition to any and all
damages deemed fair by the Arbitrator(s). Nothing contained herein shall deprive

the performance of its obligations hereunder in the event performance of this
Agreement is prevented by FORCE MAJEURE and such excuse shall continue as long

days after the termination of such condition. For purposes of this Agreement,
FORCE MAJEURE is defined as follows:

                  Causes beyond the control of GEN-PROBE or SPECIALTY including
         acts of God; war; any regulations, acts, rules, orders, proclamations,
         requirements or laws of any government; civil commotion; strike,

        11.2.   SPECIFIC PERFORMANCE AND INJUNCTION. The Parties agree that
irreparable damage will occur in the event that the provisions of Article VI are
not specifically enforced. In the event of a breach or threatened breach of any
such provisions, SPECIALTY agrees that GEN-PROBE shall, in addition to all other
remedies, be entitled to temporary or permanent injunction, without showing any
actual damage or that monetary damages would not provide an adequate remedy and

performance, in accordance with the provisions hereof.

        11.3.   GOVERNING LAW. This Agreement will be construed and governed by
the laws of the State of California, without giving effect to conflict of law

implied, is intended to confer on any person other than the Parties hereto or
their permitted assigns, any benefits, rights or remedies.

and without effect. For purposes of this Agreement, "assignment" shall include
(I) the transfer of substantially all of the assets of a party, even if this
Agreement is specifically excluded from such transfer and (II) any change in the
ultimate beneficial control of a Party. Notwithstanding the foregoing, either
Party may assign and transfer this Agreement, including all its rights and

the affected provisions of the Agreement shall be conformed and limited only to
the extent necessary to bring it within the applicable legal requirements.

        2.1     This Agreement shall commence on October 18, 1999 and continue
                for a three (3) year period or until terminated in accordance
                with this Agreement. In consideration for Unilab's Agreement to
                enter into a three-year term,

                (a)     Effective the date hereof, [***]* for the Unilab Tarzana

                (b)     Effective December 1, 1999, [***]* for the Unilab

                        in the Unilab Northern Locations.

        2.2     TERMINATION WITH CAUSE. Either party may terminate this
                Agreement with cause upon thirty (30) days' notice to the other
                party. "Cause" is hereby defined as a material breach by either
                party to comply with any of the terms of this Agreement after
                thirty (30) days written notice of such failure or violation by
                the other party giving notice of such default or non-compliance
                and written notice of its intention to so terminate unless
                within such sixty (60) day period the defaulting party has cured
                the default.

        2.3     RENEWAL. Upon expiration, this Agreement shall automatically
                renew for successive renewal terms of one (1) year each, unless
                either party shall have provided the other with ninety- (90)
                day's advance written notice of its intent not to so renew.

3.      MINIMUM REQUIREMENTS

        During the term of this Agreement, Unilab shall send to SPECIALTY for
        testing (90%) of all specimens referred to non-Unilab clinical
        laboratories for testing (the "Minimum Requirements," providing that
        SPECIALTY offers and desires to perform such tests for Unilab. The test
        mix shall be in the same ratio, except in those circumstances where such
        tests are no longer sent out [tests are conducted in-house], as in the
        base period of August, 1999, and a payor and collection mix is
        substantially the same ratio as set forth on Attachment B.

        Notwithstanding the foregoing, effective upon a change of control of
        Unilab (as defined in Section 17), or the purchase by Unilab of a
        Licensed Clinical Laboratory with a test menu materially broader than
        that of Unilab, the Minimum Requirements shall require Unilab to send to
        SPECIALTY for testing a volume of specimens which will result in net
        revenues (i.e. net of discounts, allowances and bad debts) of at least
        $800,000 per month, provided however that Specialty makes a commercially
        reasonable effort to collect payments from Third Party Payors and
        Patients and that SPECIALTY's collection rate is materially similar to
        Unilab's experience during the period of January through August 1999.
        The test mix shall be in the same ratio, except in those circumstances
        where such tests are no longer sent out [tests are conducted in-house],
        as in the base period of August 1999, and a payor and collection mix is
        in substantially the same ratio as set forth on Attachment B.

4.      LICENSURE AND ACCREDITATION

        SPECIALTY is a duly licensed independent clinical laboratory and fully
        accredited by the College of American Pathologists and CLIA, among other
        certifying agencies. SPECIALTY agrees to maintain such licensure and
        accreditation during the term of this Agreement. SPECIALTY shall
        maintain at all times during the term of this Agreement, appropriate
        professional liability coverage.

5.      SUPPLIES

        SPECIALTY shall provide, at no cost to Unilab, all necessary supplies
        for the proper preparation and submission of specimens to SPECIALTY.

6.      COURIERS AND LOGISTICS
