| | (b) | Minimums. Digene shall be required to purchase at least
[*******] Products during the period from twelve (12) months
following the delivery date of the first Product meeting all
specifications, including UL and CE certifiable configurations,
defined in the Quality Agreement attached as Exhibit A (the
Accepted Product), as follows: (i) a minimum of [*******]
Products before six (6) months following the delivery date of the
Accepted Product, and (ii) an aggregate minimum of [*******]
Products before the end of the first twelve (12) month period.
Digene shall be required to purchase a minimum of [*******] Products
during the subsequent twelve (12) month period, and for each
subsequent twelve (12) month period thereafter during the remaining
term of the Agreement (or a pro rata portion thereof in the period
during which the Agreement terminates). If Digene fails to purchase
the foregoing minimum quantities in any of the specified periods,
Digene shall be permitted to cure such failure within 45 days from
the date Digene receives written notification from Qiagen
Instruments describing such failure. If Digene does not cure such
failure or otherwise resolve it to Qiagen Instruments satisfaction,
Digenes right to have Qiagen Instruments manufacture the customized
gripper and specialized shaker with clamps on an exclusive basis
will be converted to non-exclusive.

2.3. Purchase Orders.All orders for Products shall be generated from
Digene and shall be for a minimum of [*******] instruments (or any multiple
thereof). Digene may place Purchase Orders for Products from Qiagen
Instruments at any time; provided, however, that Purchase Orders given with

Digenes binding quantity commitment for the applicable period by more
than [*******] without Qiagen Instruments prior consent, and the Purchase
Orders in any twelve (12) calendar month period may not exceed Digenes total
forecast for that twelve (12) calendar month period by more than [*******]
without Qiagen Instruments prior consent. Digene shall order Products by
issuing facsimile, telephonic orders or written Purchase Orders. Digene shall
issue a confirming written Purchase Order within two (2) days after issuing any
facsimile or telephonic order. Each Purchase Order shall specify Product
number, Product description, quantity, delivery schedule and total price of the
Purchase Order. Qiagen Instruments shall confirm in writing its acceptance of
a Purchase Order within five (5) days after receipt of the written Purchase
Order. Any Product delivered later than the schedule set forth in the Purchase
Order and in accordance with Exhibit F due to Qiagen Instruments failure to
ship timely shall result in a price reduction of [*******] per week until
delivery.

2.4. Exclusive Supplier and Buyer.Except as otherwise provided herein,
Digene shall exclusively purchase all Products from Qiagen Instruments and
Qiagen Instruments shall exclusively manufacture and sell the Products to
Digene during the term described in Section 2.1 above.

2.5. Pricing.Unit pricing for Products sold under this Agreement
includes QC, packaging, labeling, and Certificate Of Analysis (COA). The
pricing schedule following the Effective Date is specified in Exhibit D, and
the price per unit decreases in stages as the amount of units forecasted to be
purchased by Digene increases. In the event Digene fails to purchase all of
the forecasted Products during the 12-month period following each Anniversary
Date, Qiagen Instruments shall be refunded the price differential in accordance
with Exhibit D, so that Qiagen Instruments shall have received the price per
unit applicable to the lower number of Products actually purchased and received
by Digene. In the event Digene purchases additional products over the amount
of the forecasted products during the 12-month period following each
Anniversary Date, Digene shall be refunded the price differential in accordance
with Exhibit D, so that Qiagen Instruments shall have received the price per
unit applicable to the increased number of Products actually purchased and
received by Digene. Prices may be increased every 12 months by Qiagen
Instruments by an amount not to exceed the published rate of inflation
corresponding to the previous 12-month period as published in the Wall Street
Journal. Qiagen Instruments shall provide to Digene three-month advance notice
of a pending price increase.

2.6. Freight; Shipping.Delivery of Products to Digene or its designee
shall be FOB Qiagen Instruments facility in Switzerland. Digene shall be
responsible for all freight, shipping and insurance costs and expenses incurred
in connection with the shipment of the Products. Digene may choose its own
freight forwarder and shall be billed directly if it chooses to do so.

2.7. Risk of Loss.Title, possession and risk of loss of Products shall
pass to Digene upon delivery of the Products to the courier selected by Digene
at Qiagen Instruments facility in Switzerland.

Digene gives Qiagen Instruments notice within twenty (20) days after Digenes
receipt of such Products at their destination that any such Product is
defective, damaged or fails to conform to the Digene Material Specifications;
provided that Digenes acceptance shall not limit Qiagen Instruments Warranty
under Article III hereof. If Digene rejects any or all of a shipment of
Products, then Digene shall promptly notify Qiagen Instruments in writing
thereof (in any event not later than twenty (20) days after receipt as set
forth above), which notice shall provide reasonable detail of the defects,
damage or failure to conform in order to enable Qiagen Instruments to verify

hereunder with respect to any patent, copyright or trade secret infringement or
claim thereof based upon the following:

| |     |

|
| | (b) | Use of the Product by Digene in combination with devices or
Products not purchased hereunder where the Product would not itself

|
| | (e) | Any claim of infringement of a patent, copyright or trade
secret in which Digene or any affiliate or customer of Digene has an
interest or license.

and hold Digene and its affiliates and each of their officers, directors,
employees, agents and consultants harmless from and against any damages,
claims, liabilities, losses, judgements, awards, fines, penalties, costs and
expenses (including reasonable attorneys fees and court costs) incurred by
Digene as a result of or arising from Qiagen Instruments failure to perform

except for claims arising directly from the acts, omissions or negligence
of Digene; provided that:

| |     |                                                                                                                                                                  
| | --- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------
| | (a) | Digene shall have promptly provided Qiagen Instruments
written notice thereof and reasonable cooperation, information and
assistance in connection therewith, and
|
| | (b) | Qiagen Instruments shall have sole control and authority with
respect to the defense, settlement or compromise thereof.                                          

5.3. By Digene.Digene shall indemnify, defend and hold Qiagen

limitation, product liability, customer warranty and service claims except for

written notice thereof and reasonable cooperation, information and
assistance in connection therewith, and

5.4. Failure to Deliver Timely.Upon failure by Qiagen Instruments to
deliver Products on a timely basis in accordance with the delivery schedules
set forth in Exhibit F hereto, which failure continues for any reason (other
than for a force majeure) for greater than sixty (60) days, Qiagen Instruments
shall provide a written document stating the reason(s) for the non-delivery and
the resolution and plans for delivery of Products on a timely basis. Failure
on the part of Qiagen Instruments to implement said plan within the following
sixty (60) day period shall give Digene the option, but not the obligation, to
terminate this Agreement upon written notice to Qiagen Instruments, such
termination to be effective immediately. Alternatively, at the end of such
120-day period, Digene shall have the right, if Digene elects not to terminate
this Agreement, to cause Qiagen Instruments to enter into an agreement with an
alternative manufacturer selected by Qiagen Instruments and approved by Digene
(which approval shall not be unreasonably withheld) for the manufacture of
Products for Digene. In such event, Qiagen Instruments shall grant a
non-exclusive license to such alternative manufacturer of all technical
information, design work, sketches, drawings, specifications, processes,
prototype models and other proprietary information held by Qiagen Instruments
applicable to the formulation, manufacture and assembly of the Product
(collectively the Production Materials), for the sole purpose of
manufacturing Products for Digene. Such license shall be for a term not longer
than the greater of twelve (12) months or until such earlier time as Qiagen
Instruments demonstrates to Digenes reasonable satisfaction that it has the
ability to satisfy Digenes forecast for the

Purchase Orders by Digene that exceed the amount permitted in Section 2.3
hereof.

5.5. Remedies Upon Event of Default.Upon the occurrence of an Event of
Default (as defined below) by the other Party, any Party shall have the right

| | (a) | The Parties recognize that bona fide disputes as to certain
matters may arise from time to time during the term of this
Agreement which relate to either Partys rights and/or obligations.
For any and all claims, disputes or controversies arising under, out
of, or in connection with this Agreement, including any dispute
relating to patent validity or infringement, which the Parties shall
be unable to resolve (hereinafter a Dispute), the Party raising
the Dispute shall promptly advise the other Party of the Dispute in
writing, which writing shall describe in reasonable detail the
nature of the Dispute. The Parties shall thereafter attempt to
resolve the Dispute by good faith negotiations between their
respective presidents (or their equivalents) within thirty (30) days
after such notice is received (all references to days in this
Section 6.3 are to calendar days). If the matter has not been
resolved within thirty (30) days of the notice of the Dispute, or if
the Parties fail to meet within such thirty (30) days, the Dispute
shall be submitted to binding arbitration as provided in Section
6.3(b) below.                                                                                                                                                                                                                                                         
|
| | (b) | If the Parties have not been able to resolve the Dispute
pursuant to Section 6.3(a) above, the Dispute shall be finally
settled by binding arbitration as provided in this section. Unless
otherwise agreed by the Parties and except as otherwise provided in
this Agreement, any such arbitration shall be conducted (i) under
the Rules of Arbitration of the International Chamber of Commerce
(ICC), (ii) in The Hague, The Netherlands, and (iii) using the
English language. The arbitration shall be conducted before three
(3) arbitrators chosen according to the following procedure: each
of the Parties shall appoint one arbitrator and the two so nominated
shall choose the third. If the arbitrators chosen by the Parties
cannot agree on the choice of the third arbitrator within fourteen
(14) days of their appointment, then the third arbitrator shall be
appointed by the ICC in accordance with its Rules of Arbitration;
provided, that, under no circumstances shall the third arbitrator be
an employee, director, or shareholder of either Party or any of
their affiliates. Discovery (including, without limitation, the
examination of witnesses and the review of relevant documents) shall
be permitted upon a reasonable showing of a Party that fairness
requires that such Party have access to witnesses, documents or
other relevant evidence. The arbitrator(s) shall have the

the Parties the costs of arbitration in such equitable manner as
they determine. The arbitral award shall be final, binding and
non-appealable, unless manifestly contrary to the terms of this
Agreement or applicable facts or law, and may be entered in any
court of competent jurisdiction. The existence of the Dispute, any
settlement negotiations, the arbitration proceeding, any
submissions (including exhibits, testimony, proposed rulings, and
briefs), and the rulings shall be deemed Confidential Information,
and the arbitrators shall have the authority to impose sanctions
for unauthorized disclosure of Confidential Information. The
arbitrators may not, under any circumstances, make any award or
determination contrary to the terms of the Agreement.

6.4. Governing Laws.The laws of the State of Delaware shall govern this
Agreement and performance under this Agreement.

6.5. Severability.If any provision of this Agreement is invalid under
any applicable stature or rule of law, it is to that extent to be deemed
omitted, and the remainder of the Agreement shall be valid and enforceable to
the maximum extent possible.

6.6. Signatures Required; Two Originals.This Agreement shall not be
binding or effective on either Party unless and until each Party has executed
this Agreement by a corporate representative with authority to sign below.
Each Party shall execute two copies of this Agreement, and each executed copy
shall be considered an original for all purposes. The Party executing this
Agreement shall forward to the other Party one of the two executed originals as
soon as practical by mail to the address indicated above for notice.

6.7. Section Headings.The article and section headings contained in this
Agreement are for reference purposes only and shall not in any way control the
meaning or interpretation of this Agreement.

6.8. No Third Party Beneficiaries.Nothing expressed or implied in this
Agreement is intended or shall be construed to confer upon or give any person
other than the parties hereto any rights or remedies under this Agreement.

6.9. Assignment and Corporate Reorganization.This Agreement is personal
to the parties and shall not be assigned or transferred in whole or in part to
any third party without the expressed written permission of the other Party.
Furthermore, any attempted assignment shall be deemed null and void. Any
attempt to assign or transfer this Agreement by any Party without written
permission from the other Party shall be considered to be a material breach of
this Agreement and would excuse any further performance by the other Party.
However, this provision shall not apply with respect to any assignment of this
Agreement to any affiliate or if such assignment is part of a merger of either
Party with and into another company or sale of all or substantially all of the
assets of either Party to a third party, provided that in connection with the
sale of assets (A) such third party agrees to assume all obligations and
liabilities of such

Party set forth in this Agreement; and (B) such Party is not in default of
its obligations under this Agreement at the time such assignment takes place.

6.10. Injunctive Relief.If either Party breaches the provisions of
Section 2.16 of this Agreement, the injured Party shall, without limiting its
other rights or remedies, be entitled to equitable relief, including but not
limited to, injunctive relief, because the unauthorized use, transfer or
dissemination of Confidential Information provided by the injured Party to the
breaching Party may substantially diminish the value of such information and
may irreparably harm the injured Party. In addition, Digene shall be entitled
to an injunction ordering specific performance of Qiagen Instruments
obligation to grant a limited license to the Production Materials under the
circumstances and subject to the conditions described in Section 5.4 hereof.

6.11. Relationship of the Parties.Neither Party shall be responsible for
the acts or omissions of the other Party, and neither Party shall have
authority to speak for, represent or obligate the other Party in any way
without prior written authority from the other Party.

6.12. Entire Agreement.This Agreement and the Quality Agreement together
constitute the entire agreement between Qiagen Instruments and Digene with
respect to the subject matter hereof and shall not be amended, altered or
changed except by a written agreement signed by the parties hereto. Any terms
and conditions in any Purchase Order or other instrument issued by Digene or
any of its customers in connection with this Agreement or the Quality Agreement
which are in addition to or inconsistent with the terms and conditions of this
Agreement or the Quality Agreement shall not be binding on Qiagen Instruments.
Each of Qiagen Instruments and Digene acknowledges that it is not entering into
this Agreement or the Quality Agreement on the basis of any representations not
expressly contained herein.

6.13. Waivers.No delay or omission on the part of either Party to this
Agreement in requiring performance by the other Party or in exercising any
right hereunder shall operate as a waiver of any provision hereof or of any
right or rights hereunder; and the waiver, omission or delay in requiring
performance or exercising any right hereunder on any one occasion shall not be
construed as a bar to or waiver of such performance, or right, or of any right
or remedy under this Agreement, on any future occasion.

6.14. Rights and Remedies.All rights and remedies of either Party
hereunder shall be cumulative and may be exercised singularly or concurrently.
The failure of either Party, in any one or more instances, to enforce any of
the terms of this Agreement shall not be construed as a waiver of future
enforcement of that or any other term.

6.15. Counterparts.This Agreement may be executed in one or more
counterparts, each of which shall be deemed an original but all of which
together shall constitute one and the same instrument.
