(without right to sublicense) in the Licensed Field to make, have made, import,
export, use, offer to sell, sell, distribute (directly or indirectly), consign
and market any Licensed Product and Method under the OVION Patent Claims. OVION
has not and will not grant further licenses in the Licensed Field for the OVION
Patent Claims. OVION retains all rights to practice the subject matter of OVION
Patent Claims and retains all other substantial rights related to the OVION
Patent Claims. Notwithstanding the foregoing, nothing in this Section or
Agreement shall be construed as granting OVION any rights or license (implied or
expressed) to any CONCEPTUS intellectual property, including but not limited to
patents and patent applications.

III.     CONCEPTUS PAYMENTS

                  In consideration of all terms and conditions of this
Agreement, CONCEPTUS shall pay OVION the following:

         3.1      Pre-Paid Royalty. On or before ten (10) days after the
Effective Date, CONCEPTUS shall make a non-refundable payment to OVION of two
million dollars (U.S. $2,000,000), which shall be applied against royalties, if
any, that may ever become due under Section 3.3 below.

         3.2      Guaranteed Payment. (a) On or before January 31, 2004,
CONCEPTUS shall issue to OVION a non-refundable payment of one million dollars
worth of unrestricted, freely tradable CONCEPTUS common stock as provided in
Securities and Exchange Commission Staff Legal Bulletin Number 3 dated October
20, 1999 and subject to the Court's approval referenced in Section 6.2, with the
precise number of

                                                                               4

<PAGE>

shares being determined using the average closing price of the stock per the
Wall Street Journal over the ten (10) trading days preceding the day it is
issued to OVION and (b) on or before April 30, 2004 CONCEPTUS shall issue to
OVION a non-refundable payment of an additional one million dollars worth of
unrestricted, freely tradable (as provided in (a) above) CONCEPTUS common stock,
with the precise number of shares being determined using the average closing
price of the stock per the Wall Street Journal over the ten (10) trading days
preceding the day it is issued to OVION. The share certificates representing the
foregoing shares shall be delivered to OVION as soon as reasonably practical but
in any event within 5 business days after their respective issuance date.

         3.3      Running Royalty. CONCEPTUS shall pay OVION a royalty on Net
Sales for the 10-year period consisting of October 1, 2003 to September 30, 2013
as follows:

<TABLE>
<CAPTION>
Cumulative Net Sales                    Rate
--------------------                    ----
<S>                                     <C>
0 - $75,000,000                            0%
Over $75,000,000                        3.25%
</TABLE>

The royalty shall be fully paid up after September 30, 2013.

         3.4      Royalty Coverage. Solely for purposes of determining royalties
under this Agreement including the determination of whether royalties are due in
an action for relief under and pursuant to this Agreement and for no other
purpose, CONCEPTUS agrees that the Asserted Claims of U.S. Patent No. 6,432,116
(claims 13-15, 25, 30, 31, 34, 35, 41-44, and 46) cover the Licensed Products
and Methods. CONCEPTUS shall have no obligation to pay royalties during any time
period when no valid, enforceable OVION Patent Claim, including but not limited
to the Asserted Claims of U.S. Patent No. 6,432,116, covers the Licensed
Products or Methods. Each issued OVION Patent Claim shall be presumed valid and
enforceable unless or until such claim is held invalid or unenforceable by a
final, non-appealable determination. No refund shall apply to royalties due
prior to such a final determination.

         3.5      Reporting. Starting with the first quarter of 2004, CONCEPTUS
shall deliver to OVION a royalty report identifying the products upon which
royalties are being paid and setting forth total Net Sales for all
royalty-bearing sales provided by this Agreement and continuing quarterly
thereafter for the remainder of the time period set forth in Section 3.3. Each
royalty report shall be delivered on or about the same day as CONCEPTUS files
its Form 10Q or Form 10K with the Securities and Exchange Commission and shall
be accompanied by the royalty payment, if any, then due in accordance with such
report. Royalties on sales occurring outside the United States shall be
converted to United States dollars consistent with Generally Accepted Accounting
Principles.

                                                                               5

<PAGE>

         3.6      Records. CONCEPTUS and its responsible Subsidiaries shall keep
true and accurate books and records with respect to sales under this Agreement
in accordance with customary accounting principles and in a manner consistent
with the accounting methods employed throughout its business. Further, OVION
shall have the right to engage an independent auditor or certified public
accounting firm to review the relevant books and records of CONCEPTUS and its
responsible Subsidiaries during normal business hours on reasonable notice once
each anniversary year to determine the accuracy of royalty reports and payments
provided for herein. CONCEPTUS and its responsible Subsidiaries shall cooperate
with the independent auditor or certified public accounting firm to provide an
accurate opinion, consistent with generally accepted accounting principles,
concerning the accuracy of royalty reports and payments submitted to OVION. If
the OVION audit concludes that the subject royalty payment due exceeds by ten
(10%) percent the actual royalty paid, then CONCEPTUS shall pay the reasonable
fees and expenses of OVION's independent auditors or certified public accounting
firm.

         3.7      Purposes of Payments. The payments and royalty rates set forth
in this Agreement are in settlement for the Litigation.

IV.      MUTUAL RELEASES

         4.1      By OVION, TREMULIS and CALLISTER. Except as to such rights or

in which their representatives individually or collectively hold or have held

relating in any way to, claims made by, or which could have been made by OVION,
TREMULIS and/or CALLISTER, including, but not limited to, the claims asserted in
the Litigation, and any other claims under federal or state law that could have
been brought by OVION, TREMULIS and/or CALLISTER against CONCEPTUS or any other
person and/or entity released by this paragraph arising out of or in any way
connected with the Litigation or which could have been asserted in the
Litigation ("OVION Released Claims"). It is the intention of OVION, TREMULIS
and/or CALLISTER in executing this Agreement that this Agreement shall be deemed
effective as a full and final accord and satisfaction and release.

                                                                               6

         4.2      By CONCEPTUS. Except as to such rights or claims as may be
created by this Agreement, CONCEPTUS, on its own behalf, and on behalf of its
predecessors, successors, assignees, agents, principals, partners, servants,
directors, officers, affiliates, shareholders, employees and other
representatives (including consultants, attorneys and accountants), and any
trusts, trustees and beneficiaries of trusts in which their representatives
individually or collectively hold or have held any interest and anyone claiming

fully and forever release OVION, TREMULIS and/or CALLISTER and each of their

federal or state law that could have been brought by CONCEPTUS against OVION,
TREMULIS and/or CALLISTER or any other person and/or entity released by this
paragraph arising out of or in any way connected with the Litigation or which
could have been asserted in the Litigation ("CONCEPTUS Released Claims"). It is
the intention of CONCEPTUS in executing this Agreement that this Agreement shall
be deemed effective as a full and final accord and satisfaction and release.

                    WAIVER OF CALIFORNIA CIVIL CODE SECTION 1542

         4.3      It is the desire of the Parties to fully, finally, and forever
settle, compromise, and discharge any and all disputes and claims between them
arising from or relating to each and every cause of action and theory of
liability in the Litigation. Accordingly, OVION, TREMULIS and CALLISTER and
CONCEPTUS each waive all rights and benefits afforded by Section 1542 of the
Civil Code of the State of California as to unknown claims arising from or
relating to each and every of the claims, causes of action or theories of
liability in the Litigation, and do so understanding the significance of that
waiver. Section 1542 provides:

                  A GENERAL RELEASE DOES NOT EXTEND TO CLAIMS WHICH THE CREDITOR
                  DOES NOT KNOW OR SUSPECT TO EXIST IN HIS FAVOR AT THE TIME OF
                  EXECUTING THE RELEASE, WHICH IF KNOWN BY HIM MUST HAVE
                  MATERIALLY AFFECTED HIS SETTLEMENT WITH THE DEBTOR.

                                                                               7

V.       ADDITIONAL OBLIGATIONS

         5.1      Obligations of OVION, TREMULIS and CALLISTER

                  (a)      Covenant Not To Sue. Except for actions for relief
under this Agreement, OVION, TREMULIS and CALLISTER on behalf of themselves and
the other releasing parties referenced in Section 4.1 covenant that they will
not sue or assert in any way, in or out of a domestic or foreign legal,
equitable or administrative proceeding any claim or cause of action against
CONCEPTUS and/or its Subsidiaries, the parties released in Section 4.1 and their
respective direct or indirect distributors and customers in the future with
respect to Licensed Products and Methods in the Licensed Field; provided
however, that this Section 5.1(a) shall not apply to (i) patent infringement of
patent claims of OVION, TREMULIS, or CALLISTER for inventions not conceived as
of October 22, 2003 and (ii) tortious acts of CONCEPTUS which first occurred
after October 22, 2003.

         (b)      Right of First Refusal.

                  (i)      If any of OVION, TREMULIS, CALLISTER, and/or any
holder of any equity interest in OVION (any of the foregoing, an "Offeror")
propose to make a Transfer, then such Offeror shall promptly give written notice
(the "Transfer Notice") to CONCEPTUS at least 45 days prior to the closing of
such Transfer. The Transfer Notice shall describe in reasonable detail the
proposed Transfer including, without limitation, the property to be transferred
(the "Offered Interest"), the nature of such Transfer, the consideration to be
paid for the Offered Interest and the name and address of each prospective
purchaser or transferee.

                  (ii)     For 30 days following the date of such Transfer
Notice or such longer period as is necessary to resolve any disputes pursuant to
Section 5.1(b)(vi) (the "ROFR Period"), CONCEPTUS shall have the option to
purchase all of the Offered Interest specified in the Transfer Notice at the
price and upon the terms set forth in the Transfer Notice (subject to any
adjustments to the price pursuant to Section 5.1(b)(vi)). In the event CONCEPTUS
elects to purchase the Offered Interest, it shall give written notice (the
"Election Notice") to the Offeror of its election prior to the end of the ROFR
Period and settlement for said Offered Interest shall be made as provided below
in Section 5.1(b)(iii). Failure of CONCEPTUS to provide the Election Notice
prior to the end of the ROFR Period shall constitute a waiver by CONCEPTUS of
its option to purchase the Offered Interest specified in the Transfer Notice.

                  (iii)    In the event CONCEPTUS elect(s) to acquire the
Offered Interest as specified in the Transfer Notice, settlement thereof shall
be made either in cash or shares of freely tradable common stock of CONCEPTUS
(other than the effects of Rule 145 of the Securities Act of 1933, if
applicable), or a combination of the foregoing, in each case at the election of
CONCEPTUS, within 15 days following the end of the ROFR Period.

                                                                               8

<PAGE>

                  (iv)     The exercise or non-exercise of the rights of
CONCEPTUS hereunder to participate in one or more Transfers made by any Offeror
shall not adversely affect CONCEPTUS' rights to participate in subsequent
Transfers by any Offeror pursuant to this Section 5.1(b).

                  (v)      If the right of first refusal set forth in Section
5.1(b) is not exercised in full by CONCEPTUS, the Offeror may, not later than 30
days following the end of the ROFR Period and subject to the provisions of this
Section 5.1(b), enter into an agreement providing for the closing of the
Transfer of the Offered Interest covered by the Transfer Notice within 30 days
of such agreement on terms and conditions not materially more favorable to the
transferee(s) than those described in the Transfer Notice (as adjusted pursuant
to Section 5.1(b)(vi)). Any proposed Transfer on terms and conditions materially
more favorable to the transferee(s) than those described in the Transfer Notice
(as adjusted pursuant to Section 5.1(b)(vi)) as well as any subsequent proposed
Transfer by any Offeror, shall again be subject to the right of first refusal of
CONCEPTUS and shall require compliance by the Offerors with the procedures
described in this Section 5.1(b)

                  (vi)     If the Transfer of the Offered Interest is to be
settled with property other than cash or securities traded on a national
securities exchange or NASDAQ, at any time during the ROFR Period, CONCEPTUS may
object to the valuation of the Offered Interest as set forth in the Transfer
Notice by delivering to the Offeror a notice (a "Notice of Disagreement")
containing the basis for such objection together with such additional
information as shall be reasonably necessary to resolve such disagreement.
CONCEPTUS and the Offeror shall use commercially reasonable efforts to resolve
all matters raised in the Notice of Disagreement within 15 days of the date of
the Notice of Disagreement. If, at the end of such period, CONCEPTUS and the
Offeror are unable to resolve such disagreements, CONCEPTUS and the Offeror
shall jointly select an independent third-party appraiser or valuation
consultant (the "Appraiser") of recognized national standing to resolve any
remaining disagreements. The determination by the Appraiser of the value of the
Offered Interest shall be final, binding and conclusive on the parties for
purposes of the determination of consideration to be paid for such Offered
Interest. CONCEPTUS and the Offeror shall use their commercially reasonable
efforts to cause the Appraiser to make its determination within 30 calendar days
of accepting its selection. The fees and expenses of the Appraiser shall be
borne by OVION and CONCEPTUS equally.

                  (vii)    The provisions of this Section 5.1(b) shall have no
applicability to any Transfer agreements that are entered into after September
30, 2006. This Section 5.1 (b) shall not apply to any license or encumbrance of
OVION Patent Claims solely outside of the Licensed Field.

         5.2      Obligations of CONCEPTUS

                  (a)      CONCEPTUS agrees that it shall not file a lawsuit or
request for reexamination seeking to invalidate or render unenforceable or
challenging the ownership

                                                                               9

<PAGE>

of any of the claims of U.S. Patent Numbers 6,432,116 and 6,096,052 or seeking a
finding of non-infringement of the claims of U.S. Patent Numbers 6,432,116 and
6,096,052 with respect to the Licensed Products and Methods. This Section 5.2(a)
shall not apply to defenses, claims or counter claims for products or patents
outside this Agreement.

                  (b)      Notwithstanding Section 5.2 (a), CONCEPTUS will not
be precluded from seeking to invalidate or render unenforceable or challenging
the ownership of any of the claims of U.S. Patent Numbers 6,432,116 and
6,096,052 or seeking a finding of non-infringement of the claims of U.S. Patent
Numbers 6,432,116 and 6,096,052 in any litigation filed against CONCEPTUS or its
Subsidiaries, except as provided in Section 5.2 (c) below.

                  (c)      In any action for relief under and pursuant to this
Agreement, CONCEPTUS will not argue that any of the Asserted Claims, as they
currently read, are invalid or unenforceable or not infringed as a defense to
the payment of royalties under Section 3.3. Nothing in this Section 5.2 or
Agreement shall be construed to diminish the effects of Section 10.1.

                  (d)      Nothing in this Agreement shall be construed as
preventing CONCEPTUS from provoking or maintaining any interference proceeding.

         5.3      Survival. The obligations of this Article V shall survive and
remain in effect notwithstanding the assignment of this Agreement pursuant to
Article XI or the termination of this Agreement for any reason except for a
material breach by any Party.

VI.      DISMISSAL OF THE LITIGATION

the other party in writing. Such notice shall provide details of such

X.       SETTLEMENT OF DISPUTES

         10.1     Arbitration. Any dispute between the parties concerning the
construction, interpretation, and effect of this Agreement or any clause herein
contained, or the rights and liabilities or damages of the parties hereunder
shall be resolved, if necessary, by binding arbitration with a three member
arbitration panel (where at least two of members shall have been admitted before
the United States Patent and Trademark Office) in accordance with the commercial
arbitration rules of the American Arbitration Association, and judgment upon the
award rendered by the arbitrator may be entered in any court having jurisdiction
thereof. The locale of the arbitration shall be San Mateo County, California.
OVION and CONCEPTUS shall share the costs of the arbitration and each party
shall pay its own costs and attorneys' fees. In any arbitration under this
Article X or in any judicial proceeding to enforce an arbitration award,
CONCEPTUS will not argue that any of the Asserted Claims, as they currently
read, are invalid or unenforceable or not infringed as a defense to the payment
of any Royalties under Section 3.3. Notwithstanding the foregoing, in any
arbitration under this Article X, the arbitration panel shall have the
discretion to award to the prevailing party its share of the arbitration costs
and its reasonable costs and attorney fees if the panel determines that the

                                                                              14

non-prevailing party acted in bad faith or that its positions as a whole in the
arbitration were taken in bad faith.

not be unreasonably withheld or delayed.

                  (b)      Each party agrees that, without the prior written
consent of the other party or unless required by law, it shall not disclose to
any third party the terms of this Agreement or any confidential information
regarding the other party or the business of such party which has been made
available to it; except that the terms of this agreement may be disclosed to
outside legal counsel and independent outside auditors and other outside
advisors provided that such outside legal counsel and independent outside
auditors and other outside advisors agree to maintain the contents of this
Agreement in confidence.

                  (c)      Notwithstanding any other provision of this Section
11.2, if a party is required by statute, rule or regulation, including the rules
and regulations of the Securities and Exchange Commission, or under force of
process of law to disclose information related to this Agreement, such party
shall promptly notify the other party. In addition, the terms of this Agreement
may be disclosed by a party to any Court(s), mediator(s), arbitrator(s) and to
opposing counsel and outside experts in any legal proceeding concerning
indemnity, contribution or insurance owed or alleged to be owed to that party
for any payments made under this Agreement. The parties agree that such
mediator(s), arbitrator(s) and outside experts shall execute an undertaking to
keep confidential the terms of this Agreement. Disclosure of the terms of this
Agreement in such proceedings shall take place under the terms ordered by the
Court.

                  (d)      Notwithstanding any other provision of this Section
11.2, either party may disclose the contents of this Agreement to any
prospective purchaser of the

                                                                              15

assets of that party to which this Agreement relates, any investor or potential
investor, any creditor or potential creditor, financial consultants, or to any
insurance company which may be asked to pay defense costs or to indemnify,
provided that each such party agrees to maintain the contents of this Agreement
in confidence.

                  (e)      The above obligations of confidentiality shall
survive expiration or termination of this Agreement.

         11.3     Force Majeure. If for reasons of Force Majeure, as hereinafter
defined, any party fails to comply with its obligations hereunder other than the

purpose of this Article, Force Majeure shall mean acts of God; acts, regulations
or laws of any government; war; civil commotion; destruction of production
facilities or materials; fire, earthquake or storm; labor disturbances; failure
of public utilities or common carriers and any other causes beyond the

assign, transfer or delegate any of its rights or obligations hereunder, whether
by operation of law or otherwise; provided, however, that subject to the Right
of First Refusal in Section 5.1(b), either party may assign its rights and
delegate its duties in connection with a merger or consolidation with another
business entity or in connection with a sale of substantially all of its assets
to which this Agreement relates. Any assignment in derogation of the foregoing
shall be void. Subject to the foregoing, this Agreement shall be binding upon
the Parties' successors and permitted assigns.

         11.5     Exception to the Protective Order. Despite the protective
order entered by the Court in the Litigation, outside trial counsel (McAndrews,
Held & Malloy Ltd for OVION and Paul Hastings Janofsky & Walker LLP for

U.S. Patent and Trademark Office involving the patents or patent applications of
OVION or CONCEPTUS and (b) shall be entitled to maintain copies of the
pleadings, deposition transcripts and exhibits, document productions and
summaries of the same, except that business and financial records and FDA
documents of OVION and CONCEPTUS (except those FDA documents which relate to
expandability/unexpandability, a listing of which shall be discussed and agreed
to by counsel to CONCEPTUS and OVION), shall be destroyed pursuant to the
protective order. In addition, despite the protective order, OVION and CONCEPTUS
shall use reasonable efforts to agree on which information previously designated
as confidential or confidential - attorneys eyes only shall be submitted to the
U.S. Patent and Trademark Office as appropriate to satisfy 37 CFR Section 1.56.
This process shall involve an initial request for information specifically
identified by production bates number to be sent to the U.S. Patent and
Trademark Office followed by a response agreeing or not agreeing as to each
identified piece of information. The Parties shall cooperate to implement these
exceptions to the protective order.

                                                                              16
