LICENSE GRANTS

License Grant to P&G. BIOLASE hereby grants to P&G an exclusive (even as to BIOLASE), worldwide, transferable, right and license under all BIOLASE IP and BIOLASE TECHNOLOGY within the P&G FIELDS OF USE, with rights to sub-license, to make and have made, use, import, export, sell, have sold, and offer for sale P&G PRODUCTS anywhere in the world.

Conversion to Non-Exclusive License. P&G may, in its sole discretion, convert, at **** from the FIRST EFFECTIVE DATE of the PREVIOUS AGREEMENT, its exclusive license(s) under this SECOND AGREEMENT to non-exclusive license(s).

In the event the exclusive license is converted to a non-exclusive license under any of the provisions of this SECOND AGREEMENT, the royalty rates shall remain as agreed to herein (at ****). However, if BIOLASE enters into a nonexclusive license with a third party at more favorable terms than that granted to P&G, BIOLASE will offer the same terms to P&G, which P&G may accept at its sole discretion. For example, if BIOLASE grants a third party rights at a lower royalty rate than that applicable to P&G, P&G will be offered the opportunity to convert its royalty rate to the lower royalty rate granted to such third party, with such lower rate to take effect upon execution of such third party agreement.

P&G’s option to take exclusive control of prosecution and litigation of BIOLASE PATENTS under 6.1 and 7.3-7.7 will terminate in the event that the exclusive license is converted to a non-exclusive license.

Should the license from BIOLASE to P&G revert to a non-exclusive license, BIOLASE will notify P&G in writing of the commencement of any third party discussions and/or negotiations regarding BIOLASE IP. Upon receipt of notification from BIOLASE, P&G will have **** to resume exclusivity payments as described in section 4.2.1. If P&G resumes payments as described in section 4.2.1, then the license from BIOLASE to P&G of BIOLASE IP will revert from non-exclusive to an exclusive license.

P&G hereby grants to BIOLASE an exclusive (even as to P&G), worldwide, non-transferable, revocable, right and license under P&G IP within the BIOLASE FIELD OF USE, with rights to make and have made, use, import, export, sell, and offer for sale BIOLASE PRODUCTS anywhere in the world.

Unless otherwise agreed to in writing between the PARTIES, if, three years have lapsed from the EFFECTIVE DATE of this SECOND AGREEMENT, and BIOLASE has not implemented a LARGE SCALE COMMERCIAL DISTRIBUTION of a BIOLASE PRODUCT, then the exclusive license to P&G IP will revert to a non-exclusive license.

No Other Licenses Granted to BIOLASE. The licenses granted BIOLASE under this SECOND AGREEMENT are limited to those specifically set forth in Section 2.3. Nothing in this SECOND AGREEMENT will be construed to grant BIOLASE any rights or licenses to any other patent, technical information, know-how, or other intellectual property of P&G. All rights not specifically granted to BIOLASE are reserved by P&G.

No Other Licenses Granted to P&G. The licenses granted P&G under this SECOND AGREEMENT are limited to those specifically set forth in Section 2.1. Nothing in this SECOND AGREEMENT will be construed to grant P&G any rights or licenses to any other patent, technical information, know-how, or other intellectual property of BIOLASE. All rights not specifically granted to P&G are reserved by BIOLASE.

TECHNOLOGY TRANSFER

Licensed BIOLASE TECHNOLOGY and BIOLASE IP Related to the PRIMARY P&G FIELD OF USE. Upon reasonable written (including electronically) request by P&G, BIOLASE will share or transfer to P&G, relevant aspects of the BIOLASE TECHNOLOGY and BIOLASE IP licensed to P&G in the PRIMARY P&G FIELD OF USE, including, the patent applications for the BIOLASE PATENTS in Exhibit A and related patent prosecution information, including conception and reduction to practice information, and will reasonably make available to P&G for consultation those BIOLASE employees with substantive knowledge regarding the application of BIOLASE TECHNOLOGY and BIOLASE IP in the PRIMARY P&G FIELD OF USE; provided, however, that BIOLASE will not be required to provide more than **** of such consultation time per quarter to P&G and no more than **** in four **** consecutive calendar quarters. P&G and BIOLASE will appoint technical and patent liaisons who will serve as designated points of contact to develop and coordinate a timely process that is not overly burdensome for BIOLASE to effectuate said sharing of BIOLASE TECHNOLOGY and BIOLASE IP in the event P&G provides BIOLASE with a reasonable written request hereunder.

In the event that such consultation leads P&G to determine that direct involvement of BIOLASE employees and R&D resources will be beneficial to the development of products using the BIOLASE TECHNOLOGY, P&G and BIOLASE may also enter into a joint development agreement (“JDA”), or other agreement, pursuant to which BIOLASE will provide P&G with the specified testing, research, development, prototyping, production, manufacturing services or other assistance requested by P&G, to test, develop, produce and manufacture prototype P&G PRODUCTS and such other products using the BIOLASE TECHNOLOGY as P&G may request (“SERVICES”).

Licensed BIOLASE TECHNOLOGY and BIOLASE IP in P&G FIELDS OF USE (excluding the PRIMARY P&G FIELD OF USE). Upon reasonable written request from P&G, BIOLASE will share the information reasonably necessary for P&G to determine whether P&G has an interest in developing and commercializing a BIOLASE TECHNOLOGY or BIOLASE IP within the P&G FIELDS OF USE (excluding the PRIMARY P&G FIELD OF USE). Should P&G have an interest in evaluating or commercializing BIOLASE TECHNOLOGY or BIOLASE IP disclosed under this Section 3.2, BIOLASE shall disclose information to P&G which is reasonably related to P&G’s interest (including development and manufacturing information), within a commercially reasonable period of time of P&G’s request to BIOLASE.

Licensed P&G IP in the BIOLASE FIELD OF USE. P&G shall share or transfer to BIOLASE, relevant aspects of the P&G IP licensed to BIOLASE in the BIOLASE FIELD OF USE. P&G will reasonably make available to BIOLASE not more than **** with substantive knowledge regarding the application of P&G IP in the BIOLASE FIELD OF USE. P&G will provide the information in a one time workshop format which will be at least one day but not more than **** and will not be more than **** in total. Said one time workshop will occur within **** of the SIGNING DATE of this SECOND AGREEMENT. P&G and BIOLASE agree to negotiate in good faith a request made by BIOLASE to P&G for additional transferring or sharing related to this section 3.3. For the purposes of clarity P&G is not obligated to provide the requested additional assistance and may ultimately refuse to provide such additional assistance.

PAYMENTS

Milestone Payments for First P&G Product and Second P&G Product

First Product Shipment Payment. P&G shall pay BIOLASE a product launch milestone payment in the amount of **** ($****) on the terms and subject to the conditions set forth here below (the “FIRST PRODUCT SHIPMENT PAYMENT”).

The FIRST PRODUCT SHIPMENT PAYMENT shall be due ****.

Payments made under this Section 4.1.1 are non-refundable except as otherwise provided herein. For the sake of clarity, BIOLASE will be entitled to only one FIRST PRODUCT SHIPMENT PAYMENT and under no circumstance will there be another FIRST PRODUCT SHIPMENT PAYMENT.

Second Product Shipment Payment. P&G shall pay BIOLASE a second product launch milestone payment in the amount of **** ($****) on the terms and subject to the conditions set forth here below (the “SECOND PRODUCT SHIPMENT PAYMENT”).

The SECOND PRODUCT SHIPMENT PAYMENT shall be due ****.

The SECOND PRODUCT SHIPMENT PAYMENT will be treated as prepaid royalties to be deducted from any subsequent ROYALTY PAYMENTS owed under this SECOND AGREEMENT. The second P&G PRODUCT will not include cosmetic changes or minor improvements (refreshes) which do not fundamentally change the benefit delivered by the first P&G PRODUCT. The second P&G PRODUCT is one that is largely unique and different from the first P&G PRODUCT. For the avoidance of doubt, some non-limiting examples of a P&G PRODUCT that does not differ significantly from the first P&G PRODUCT are P&G PRODUCTS that incorporate only packaging changes; artwork changes; bonus packs; marketing promotions; changes to the size, color or shape of the P&G PRODUCT; the addition or elimination of minor excipients, and combinations thereof. Payments made under this Section 4.1.2 are non-refundable except as otherwise provided herein. For the sake of clarity, BIOLASE shall be entitled to only one SECOND PRODUCT SHIPMENT PAYMENT and under no circumstance will there be another SECOND PRODUCT SHIPMENT PAYMENT. For the sake of clarity and to serve as an example, if a first P&G PRODUCT ****. Further, if a first P&G PRODUCT ****.

For the sake of clarity, in no circumstance will there be a third product shipment payment.

Quarterly Payments: P&G will allow BIOLASE to remove a sum of **** ($****) per QUARTER, hereafter “P&G QUARTERLY PAYMENTS” from the PREVIOUSLY PAID QUARTERLY PAYMENTS.

Upon the conclusion of **** after the EFFECTIVE DATE of this SECOND AGREEMENT, the exclusive license granted to P&G by BIOLASE under section 2.1 shall revert to a non-exclusive license unless P&G pays to BIOLASE a QUARTERLY payment of **** ($****).

Because the EFFECTIVE DATE of this SECOND AGREEMENT is retroactive to January 1, 2009, BIOLASE will have the option to remove **** P&G QUARTERLY PAYMENTS from the PREVIOUSLY PAID QUARTERLY PAYMENTS within **** of this SECOND AGREEMENT. Again for clarity, the P&G QUARTERLY PAYMENTS shall be deducted from the prepaid royalties of the PREVIOUSLY PAID QUARTERLY PAYMENTS made by P&G to BIOLASE.

In consideration for the license to P&G IP, BIOLASE will make royalty payments (the “BIOLASE ROYALTY PAYMENTS”) to P&G based on **** of BIOLASE PRODUCTS. The BIOLASE ROYALTY PAYMENTS shall be equal to ****.

Royalty Payments on Product Sales

A PARTY will make royalty payments (the “ROYALTY PAYMENTS”) to the other PARTY based on ****of such P&G PRODUCTS or BIOLASE PRODUCTS. The ROYALTY PAYMENT shall be equal to the ****.

The royalty rate shall be **** if the P&G PRODUCT is in a **** product category where P&G currently markets products **** (see D for a non-exhaustive list). For the avoidance of doubt, a **** shall be considered a product category where **** and shall be only subject to a **** royalty in the event a royalty is applicable. The royalty rate shall be **** if the P&G PRODUCT is in a product category where ****. The **** shall not trigger a **** royalty. Further, using **** will not trigger a **** royalty. For the avoidance of doubt, ****, then a ****or **** that **** would be considered a product in a category where ****.

The royalty rate shall be **** for BIOLASE PRODUCTS.

The amount of ROYALTY PAYMENTS due shall be calculated on a **** basis from the date of **** of P&G PRODUCT or BIOLASE PRODUCT in such country. ROYALTY PAYMENTS will only be due for sales in those countries where (1) commercial sale of a P&G PRODUCT (as defined in Section 1.9) is covered by one or more **** claims; or (2) commercial sale of a BIOLASE PRODUCT (as defined in Section 1.17) occurs. ROYALTY PAYMENTS will be paid on a QUARTERLY basis and will be due on the **** of the subject QUARTER. A PARTY may elect to combine ROYALTY PAYMENTS into a single payment mechanism (e.g., a single wire transfer).

If a P&G PRODUCT is launched after the expiration of **** from the EFFECTIVE DATE of this SECOND AGREEMENT, **** will be applied as pre-paid royalties from the PREVIOUSLY PAID QUARTERLY PAYMENTS.

If a P&G PRODUCT is launched before the expiration of **** from the EFFECTIVE DATE of this SECOND AGREEMENT, the amount of money remaining in the PREVIOUSLY PAID QUARTERLY PAYMENTS to be applied as pre-paid royalties will be ****.

P&G Sublicenses to Third Parties

Sublicenses Comprising Only BIOLASE PATENTS. To the extent that P&G would have owed ROYALTY PAYMENTS for a P&G PRODUCT under this SECOND AGREEMENT, sub-licenses (comprising only BIOLASE PATENTS) from P&G to third parties will bear the same royalty rate as if P&G had made the sale. Thus, P&G agrees that the net effect of the sub-license (comprising only BIOLASE PATENTS) to third parties will not deprive BIOLASE of ROYALTY PAYMENTS.

Sublicenses Comprising BIOLASE PATENTS and P&G Intellectual Property. In the event P&G enters any agreement with a third party that includes P&G intellectual property and a grant under BIOLASE PATENTS as part of that agreement, wherein said grant to such third party to sell products under BIOLASE PATENTS and said sale would have been subject to ROYALTY PAYMENTS by P&G to BIOLASE if P&G were selling such products, P&G and BIOLASE will mutually agree to ****, and P&G will pay **** to BIOLASE. For example, if P&G elected to license a third party rights under both BIOLASE PATENTS and P&G intellectual property, and **** obligated the third party to pay P&G **** to maintain such license then BIOLASE would receive a ****.

The ****under this Section 4.5.2.1 will be ****. It is foreseeable that BIOLASE, only as applicable to this Section 4.5.2.1 may receive **** compensation, according to ****, for BIOLASE PATENTS than they otherwise would have under this SECOND AGREEMENT. In no event, however, will the **** owed to BIOLASE exceed the equivalent of a ****ROYALTY PAYMENT, as would otherwise be applicable under this SECOND AGREEMENT.

BIOLASE’s right to have made

If BIOLASE requires the use of a third party(ies) to have BIOLASE PRODUCTS made, BIOLASE will establish a confidentiality agreement with the third party(ies).

The confidentiality agreement of section 4.6.1 will be at least as restrictive as the confidentiality requirements of this SECOND AGREEMENT, including the obligation of confidentiality beyond the termination of this SECOND AGREEMENT and/or the confidentiality agreement of section 4.6.1; and

said confidentiality agreement will explicitly name P&G as an intended third-party beneficiary with all legal rights associated thereto to enforce said confidentiality agreement.

A PARTY will deliver to the other PARTY a written report of all NOS of P&G PRODUCTS or BIOLASE PRODUCTS by country, in all countries where royalty payments are due on P&G PRODUCTS or BIOLASE PRODUCTS sold, the applicable royalty rate, the amount of earned royalty, and the calculation of the ROYALTY PAYMENT due to the P&G or BIOLASE after deduction of the current total amount of payments hereunder that ****. Said royalty report will be delivered by P&G or BIOLASE within **** of the last day of the QUARTER in which they are earned.

P&G and BIOLASE will keep accurate and complete records for P&G PRODUCTS or BIOLASE PRODUCTS marketed pursuant to this SECOND AGREEMENT of: (i) its calculation of NOS for P&G PRODUCTS or BIOLASE PRODUCTS (as defined herein); and (ii) all royalties paid and payable hereunder (hereinafter such reports will collectively be referred to as “SALES AND ROYALTY RECORDS”). Such SALES AND ROYALTY RECORDS will be kept with sufficient detail to enable an independent auditor to verify such figures and to calculate NOS and total royalties paid and payable hereunder and will be retained for the TERM and for at least **** subsequent to expiration of the TERM or termination.

All payments due to P&G or BIOLASE under this Article will be made in U.S. Dollars via wire transfer to an account designated by P&G or BIOLASE. The sending PARTY will notify the receiving PARTY as indicated below prior to sending any such wire transfers.

Any SALES AND ROYALTY RECORD(S) and notification of any wire transfer(s) by P&G will be delivered to: BIOLASE TECHNOLOGY, Inc., 4 Cromwell, Irvine CA 92618, attention Richard Harrison, Chief Financial Officer and Secretary, or to his designee or successor.

Any SALES AND ROYALTY RECORD(S) and notification of any wire transfer(s) by BIOLASE will be delivered to: The Procter and Gamble Company, One Procter & Gamble Plaza, Cincinnati, Ohio 45202, attention Meg McCann.

At any time prior to the expiration of **** following the end of any calendar year, a PARTY will have the right to audit the other PARTY’s SALES AND ROYALTY RECORDS relative to this SECOND AGREEMENT, said auditor being independent, having no past relationship with either PARTY. The purpose of such audit will be to verify the calculation of gross sales for such year, NOS for such year and the royalties paid and payable hereunder for such year. A PARTY will provide at least **** advance written notice before each such audit. The audited PARTY will cooperate in such audit by allowing the other PARTY access (during audited PARTY’s normal business hours at the locations where such SALES AND ROYALTY RECORDS are kept) solely to the audited PARTY’s SALES AND ROYALTY RECORDS. Upon request by audited PARTY, the auditor may be required, as a condition of being granted access to PARTY’s SALES AND ROYALTY RECORDS hereunder, to agree to maintain any information reviewed (including, but not limited to the AUDITOR’S REPORTS (defined in Section 4.13) submitted to the PARTIES pursuant to 4.13 below) in confidence. Notwithstanding anything herein to the contrary, a PARTY may only cause an audit once in any calendar year and only once with respect to each calendar year.

At the conclusion of the auditor’s audit pursuant to Section 4.12 above, the auditor will submit a written report (herein “AUDITOR’S REPORT”) to the PARTIES setting forth the auditor’s findings with respect to the correct gross sales, NOS and total royalties paid and payable for the quarter(s) in question. If the AUDITOR’S REPORT results in findings as to gross sales, NOS or royalties which are different from those originally reported or paid by the audited PARTY, then the AUDITOR’S REPORT will include a reconciliation of the original figures with those found to be correct by the auditor and the source of such difference(s). The AUDITOR’S REPORT and its content will be treated as confidential pursuant to Section 12. If there is no challenge to the AUDITOR’S REPORT within **** after receipt of the report by the audited PARTY, and the AUDITOR’S REPORT shows an underpayment of royalties, then the audited PARTY will pay to the other PARTY within **** of expiration of the thirty day challenge period an amount sufficient to remedy the amount of any under reporting or underpayment of royalties found by the auditor plus interest calculated at the then current prime rate from the date such payment is due. If the AUDITOR’S REPORT shows an overpayment of royalties, such overpayment will be creditable against any future royalties payable in subsequent royalty periods. The cost and expense of any audit conducted hereunder will be borne by the PARTY requesting the audit unless the AUDITOR’S REPORT finds an error in requesting PARTY’s favor of at least **** of the royalties originally paid by the audited PARTY, in which case the audited PARTY will bear such cost and expense, subject to the outcome of the audit dispute resolution process specified in following section.

The PARTIES agree to work together with the auditor in good faith to resolve any disputes arising out of or relating to the numbers verified and the results reported in an AUDITOR’S REPORT in a timely, professional and non-adversarial manner. If the PARTIES and the auditor cannot so resolve a dispute, then either PARTY may submit such dispute for binding arbitration (hereinafter referred to as “ROYALTY ARBITRATION”) to a panel of three (3) arbitrators. Such ROYALTY ARBITRATION will be conducted in Cincinnati, Ohio, if brought by BIOLASE and in Irvine, California if brought by P&G. The arbitrators will be selected and the arbitration will be conducted in accordance with the Commercial Arbitration Rules of the American Arbitration Association except that the only issue for arbitration in the ROYALTY ARBITRATION will be the accuracy of the reporting and calculation of the values for gross sales, NOS, and royalties paid and payable hereunder. The arbitrators will not have power to add to, subtract from or modify any of the terms or conditions of this SECOND AGREEMENT. Any award rendered in such arbitration may be enforced by either PARTY in the courts of the State of New York, to whose jurisdiction each PARTY hereby irrevocably consents and submits for such purpose. Each PARTY will bear its own expense associated with the ROYALTY ARBITRATION. The losing party will bear the cost of the arbitration itself and will also be required to pay the other party’s attorneys’ fees associated with the ROYALTY ARBITRATION. In the event that the outcome of the arbitration is such that there is not a clear losing party, then the PARTIES agree to share the costs for the arbitration in a manner consistent with the decision of the arbitrators.

Withholding by P&G. If a law or regulation of any country in which P&G PRODUCTS are sold requires withholding of taxes of any type, levies or other charges with respect to any amounts payable hereunder to BIOLASE, P&G will promptly pay such tax, levy or charge for and on behalf of BIOLASE to the proper governmental authority, and will promptly furnish BIOLASE with receipt of such payment. P&G will have the right to deduct any such tax, levy or charge actually paid from payment due BIOLASE or be promptly reimbursed by BIOLASE if no further payments are due BIOLASE. P&G agrees to assist BIOLASE in claiming exemption from such deductions or withholdings under double taxation or similar agreement or treaty from time to time in force and will use reasonable efforts to minimize the amount required to be so withheld or deducted.

Withholding by BIOLASE. If a law or regulation of any country in which BIOLASE PRODUCTS are sold requires withholding of taxes of any type, levies or other charges with respect to any amounts payable hereunder to P&G, BIOLASE will promptly pay such tax, levy or charge for and on behalf of P&G to the proper governmental authority, and will promptly furnish P&G with receipt of such payment. BIOLASE will have the right to deduct any such tax, levy or charge actually paid from payment due P&G or be promptly reimbursed by P&G if no further payments are due P&G. BIOLASE agrees to assist P&G in claiming exemption from such deductions or withholdings under double taxation or similar agreement or treaty from time to time in force and will use reasonable efforts to minimize the amount required to be so withheld or deducted.

Payment Due Dates. Any payment due under this SECOND AGREEMENT will be paid within **** of its due date. In the event the payor does not make the payment in full by the **** after the due date, the payee will be entitled to interest in the amount of **** on any unpaid amount, from **** following the due date until such time as the payor pays the payee the amount owed.

No more than **** after the launch of a BIOLASE PRODUCT, BIOLASE will provide to P&G consumer learnings, understandings, consumer feedback, sales data, and the like. BIOLASE and P&G may, but are not required to, work on said consumer learnings, understanding, consumer feedback, sales data, and the like jointly and again at ****.

INTELLECTUAL PROPERTY OWNERSHIP

Background Intellectual Property. All IP developed, conceived or reduced to practice prior to the EFFECTIVE DATE of this SECOND AGREEMENT will continue to be owned by the respective PARTY that developed, conceived or reduced it to practice.

Ownership by P&G. P&G will continue to own P&G IP, and, except as set forth herein in section 2.3, no other rights or licenses to the P&G IP will be granted to BIOLASE.

All IMPROVEMENTS made solely by P&G (P&G IMPROVEMENTS) will be owned and retained by P&G, including IMPROVEMENTS to BIOLASE TECHNOLOGY invented or developed solely by P&G. Further, IMPROVEMENTS made solely by P&G, including patent applications comprising only such IMPROVEMENTS, are not subject to this SECOND AGREEMENT.

Ownership by BIOLASE. BIOLASE will continue to own BIOLASE TECHNOLOGY and BIOLASE IP and, except as set forth herein, no other rights or licenses to the BIOLASE TECHNOLOGY or BIOLASE IP will be granted to P&G, and BIOLASE will own any IMPROVEMENTS that BIOLASE solely develops (BIOLASE IMPROVEMENTS), conceives or reduces to practice. Where the BIOLASE IMPROVEMENTS are to the BIOLASE PATENTS, such BIOLASE IMPROVEMENTS will be licensed to P&G in accordance with the terms of this SECOND AGREEMENT.

Joint Ownership. The PARTIES will jointly own any IP that is jointly conceived under this SECOND AGREEMENT.

Pursuant to Section 3.1.1 above, the PARTIES may agree to enter into a JDA or SERVICES agreement. Terms and conditions for a JDA or SERVICES agreement will be agreed to at the time P&G and BIOLASE mutually agree to enter into such an arrangement.

PREPARATION AND PROSECUTION OF PATENT APPLICATIONS AND PATENT COSTS

Licensed BIOLASE PATENTS of Exhibit A. From the FIRST EFFECTIVE DATE of the PREVIOUS AGREEMENT and written notification from P&G, P&G will have the right, but not the obligation, to take control of the BIOLASE PATENTS listed in Exhibit A and patent applications comprising BIOLASE IMPROVEMENTS in the PRIMARY P&G FIELD OF USE and P&G/BIOLASE joint IMPROVEMENTS in the PRIMARY P&G FIELD OF USE. P&G’s right to take control as discussed above in this Section 6.1 will mean to have sole responsibility and decision making authority for the preparation, filing (including the filing of continuations, continuations-in-part, divisionals, reissues, and reexaminations), prosecution, and maintenance of the BIOLASE PATENTS listed in Exhibit A. P&G will pay all costs and expenses associated with said control in the event and to the extent P&G exercises its right to take control of one or more BIOLASE PATENTS hereunder. BIOLASE will cooperate with P&G, including giving P&G power of attorney and changing the correspondence address to P&G’s address.

In the event that P&G takes control of a BIOLASE PATENT and decides not to prosecute or maintain said BIOLASE PATENT in any particular country (including the United States), BIOLASE may take back control of that patent or application in which event BIOLASE will be responsible for all costs and expenses associated with the said BIOLASE PATENT, including costs and expenses associated with the prosecution and maintenance of said patent.

In the event P&G elects not to prosecute or maintain a BIOLASE PATENT that P&G has taken control of, P&G will provide BIOLASE with at least **** advance written notice of such decision. P&G’s written notice will be done in a good faith manner which reasonably provides BIOLASE with at **** to continue with prosecution or maintenance of that BIOLASE PATENT. In the event that BIOLASE takes control of a BIOLASE PATENT under Sections 6.1.1, such change in control will have no effect on P&G’s payment obligations under Section 4 and said BIOLASE PATENT will continue to be licensed to P&G pursuant to the license grant of Section 2.

P&G will only be responsible for the costs and expenses incurred from the time of control of a BIOLASE PATENT is taken by P&G to the sooner of (a) **** or (b) the **** from the time of notice to BIOLASE that P&G will not continue to prosecute or maintain particular BIOLASE PATENT(S).

It is P&G’s intention to achieve broad patent rights with the BIOLASE PATENTS it controls. It is further P&G’s intention to prosecute BIOLASE PATENTS in a way that protects P&G products. Both PARTIES realize that it is unforeseeable whether BIOLASE PATENTS may read upon future P&G products. BIOLASE may file divisionals, continuations and continuations-in-part in an attempt to issue claims which read on a product from the PRIMARY P&G FIELD OF USE.

Third Party Infringement in P&G FIELDS OF USE (excluding the P&G PRIMARY FIELD OF USE).

If P&G provides BIOLASE with evidence of infringement of one of the BIOLASE PATENTS listed in or to be listed in Exhibit C in the P&G FIELDS OF USE other than the P&G PRIMARY FIELD OF USE, and if P&G has initiated development, then P&G may by written notice request BIOLASE to take steps to terminate the infringement. If BIOLASE does not, within **** of receipt of such notice, take appropriate action against the alleged infringement, then:

Upon written notice to BIOLASE, P&G will have the right, but not the obligation, as exclusive licensee to institute such action in its own name as it deems appropriate to terminate said infringement through negotiation, litigation, and/or alternative dispute resolution at P&G’s expense. As exclusive licensee, P&G will have the power at its expense to institute, prosecute and settle, including by granting the infringing party a sublicense, suits for infringement of the BIOLASE PATENTS listed in or to be listed in Exhibit C under this Section 8.2.1.1 after said **** period, and if required by law, BIOLASE will join as a party plaintiff in such suits at P&G’s expense.

P&G will have the right to select and control counsel in any action initiated by P&G under Section 8.2.1.1.

Any recovery awarded or received in connection with any negotiation, settlement or suit under this Section 8.2. in excess of litigation costs will belong solely to P&G except as provided under Section 4.5.

Third Party Infringement in PRIMARY P&G FIELD OF USE.

As exclusive licensee in the PRIMARY P&G FIELD OF USE, P&G will have sole decision making authority regarding enforcement of the BIOLASE PATENTS listed or belonging in Exhibit A. P&G will have the right, but not the obligation, to file, prosecute and settle any such claims at its sole discretion.

BIOLASE agrees to cooperate with P&G with the enforcement of any claim within the PRIMARY P&G FIELDS OF USE and agrees to join, at P&G’s expense, any such action as a party plaintiff to the extent required by law.

P&G agrees that it will use reasonable efforts to consult with BIOLASE prior to the initiation of any action by P&G under Section 8.3.1. For the avoidance of doubt, said consultation under this Section 8.3.1.1 will not impair P&G’s right to, in its sole discretion, institute an action in its own name under Section 8.3.1 to terminate an infringement in the PRIMARY P&G FIELD OF USE.

P&G will have the right to control and to select counsel in any action initiated by P&G under Section 8.3.1.

To the extent that P&G is permitted to exploit a specific Product application in the BIOLASE RETAINED FIELD pursuant to Section 2.4 and a third party is infringing one of the BIOLASE PATENTS in connection with such Product application, such infringement will be treated as if it had taken place in P&G FIELDS OF USE (excluding the PRIMARY P&G FIELD OF USE) in accordance with Section 8.2.

Declaratory Judgments.

If (1) a declaratory judgment action alleging invalidity, unenforceability and/or non-infringement of any of the BIOLASE PATENTS is brought against P&G; (2) a declaratory judgment action alleging invalidity, unenforceability and/or non-infringement of any of the BIOLASE PATENTS is brought against BIOLASE for a BIOLASE PATENT under which P&G is paying BIOLASE a royalty; (3) a declaratory judgment action alleging invalidity, unenforceability and/or non-infringement of any P&G PATENTS is brought against BIOLASE; or (4) a declaratory judgment action alleging invalidity, unenforceability and/or non-infringement of any P&G PATENTS is brought against P&G, P&G may elect, in its sole discretion, to have sole control of the action, including, but not limited to, selection and control of counsel and the defense and settlement of the action, and if P&G so elects it will bear all the costs of the action and will defend against such declaratory judgment action. P&G will keep BIOLASE reasonably informed of the progress of the legal action. P&G may not agree to invalidity, unenforceability, or non-infringement of a BIOLASE PATENT or any claim thereof without BIOLASE’S prior written consent, which may not be unreasonably withheld.

Except as set forth in Section 8.7.1, if a declaratory judgment action alleging invalidity, unenforceability or non-infringement of any of the BIOLASE PATENTS is brought against BIOLASE, BIOLASE will have sole control of the action, including, but not limited to, selection and control of counsel and the defense and settlement of the action.

Except as set forth in Section 8.7.1, if a declaratory judgment action alleging invalidity, unenforceability or non-infringement of any of the BIOLASE PATENTS is brought against both PARTIES, BIOLASE will have sole control of the action, including, but not limited to, selection and control of counsel and the defense and settlement of the action.

Cooperation. Each PARTY will fully cooperate with the other PARTY, at said other PARTY’S expense, in support of any action initiated by said other PARTY under Section 8, including using commercially reasonable efforts to have its employees testify when requested and to make available relevant records, papers, information, samples, specimens, and the like.

P&G as non-exclusive licensee. If BIOLASE elects not to institute such action to terminate third party infringement under section 8.2 or 8.3, or fails to do so within such 6 months of receiving P&G’s notice of infringement under section 8.1, then P&G may bring suit against the third party infringer in P&G’s own name, and/or in BIOLASE’s own name if necessary; provided, that P&G provides written notice to BIOLASE that such infringement is causing or will cause substantial harm to P&G’s sale of P&G PRODUCT. P&G will indemnify BIOLASE against any liability resulting from such P&G enforcement against a third party infringer, provided however, that P&G will not indemnify BIOLASE against any liability directly resulting from the actions of BIOLASE’s counsel or BIOLASE’s employees or agents. BIOLASE will have the right to participate in any such suit brought by P&G at BIOLASE’s own expense and by counsel of BIOLASE’s own selection. Upon request by P&G, BIOLASE will provide reasonable cooperation in the prosecution of any such suit and will provide P&G with all available evidence supporting such infringement. P&G will reimburse BIOLASE for all BIOLASE’s reasonable expenses related to such cooperation; such expenses maybe direct out of pocket expenses and/or, internal expenses; internal expenses will be billed at BIOLASE’s internal rate. Any costs or damages recovered as a result of such enforcement action will be shared between the PARTIES 50:50, following deduction of P&G’s reasonable expenses and legal fees directly connected to the enforcement action.

ALLEGED INFRINGEMENT BY THE PARTIES

Alleged Infringement by a PARTY.

If a PARTY, any of its AFFILIATES or sublicensees, distributors or other customers are approached by or sued by a third party concerning an allegation of patent infringement for the development, manufacture, use, distribution or sale of a P&G PRODUCT or a BIOLASE PRODUCT, the alleged infringing PARTY will promptly, within reason, notify the other PARTY upon its receiving written notice of such allegation. The alleged infringing PARTY will be entitled to solely control all aspects of the defense or mitigation of any such allegations, including but not limited to, selection and control of counsel, negotiation, litigation strategy development and execution, and settlement.

In the event P&G is a party to a legal action pursuant to Section 9.1.1, BIOLASE will fully cooperate with and supply all assistance reasonably requested by P&G, including by using commercially reasonable efforts to have its employees testify when requested and to make available relevant records, papers, information, samples, specimens, and the like.

Certain Effects of Termination.

Termination by BIOLASE for P&G Uncured Material Breach. Effective upon a termination by BIOLASE in accordance with Section 11.2.1 above, the following will occur:

Except for Section 11.3.1.3, P&G’s licenses under the BIOLASE PATENTS and BIOLASE TECHNOLOGY will automatically be deemed to have terminated and all rights thereunder will automatically be deemed to have reverted to BIOLASE; and BIOLASE’s licenses under the P&G PATENTS and P&G IP will automatically be deemed to have terminated and all rights thereunder will automatically be deemed to have reverted to P&G.

P&G will destroy all copies of BIOLASE CONFIDENTIAL INFORMATION provided by BIOLASE to P&G hereunder. Notwithstanding the foregoing, and provided P&G fulfills its obligations specified in this SECOND AGREEMENT with respect to such materials, P&G’s counsel may continue to retain solely for archival purposes a single copy of BIOLASE’s CONFIDENTIAL INFORMATION and any other materials provided by BIOLASE; and BIOLASE will destroy all copies of P&G CONFIDENTIAL INFORMATION.

P&G will retain a non-exclusive, worldwide license to import, offer for sale, or sell any remaining P&G PRODUCTS that had been manufactured up to the date of termination of this SECOND AGREEMENT.

However, if BIOLASE commits an UNCURED MATERIAL BREACH, P&G may alternatively elect to retain its exclusive license(s) without the obligation to pay FIRST or SECOND PRODUCT SHIPMENT PAYMENT(S), P&G QUARTERLY PAYMENTS, ROYALTY PAYMENTS, or any other monies whatsoever, however, if P&G retains its exclusive license(s), it will not be entitled to a refund of monies previously paid. Additionally, where BIOLASE commits an UNCURED MATERIAL BREACH, P&G may revoke the license given to BIOLASE under Section 2.3, thereby terminating this SECOND AGREEMENT.

Change in Control of BIOLASE. BIOLASE will promptly notify P&G of any CHANGE IN CONTROL as the term is defined in 11.4.2, of BIOLASE or a BIOLASE AFFILIATE that is primarily responsible for undertaking the obligations under this SECOND AGREEMENT.

Further upon a CHANGE IN CONTROL event involving a direct competitor to P&G in the P&G PRIMARY FIELD OF USE, P&G may elect to terminate, modify or continue under this SECOND AGREEMENT as defined in this Section 11.4.

If the CHANGE IN CONTROL event involves a direct competitor to P&G in the P&G PRIMARY FIELD OF USE, P&G may elect, without consequence, as provided below:

P&G may elect to terminate any research, development or manufacturing activity that BIOLASE may have been conducting for P&G under this SECOND AGREEMENT or a separate agreement relating to P&G IP or BIOLASE TECHNOLOGY.

P&G may elect to continue under this SECOND AGREEMENT, including any research, development or manufacturing activity that BIOLASE may have been conducting for P&G under this SECOND AGREEMENT or a separate agreement related to this SECOND AGREEMENT, in which case P&G may request in writing that BIOLASE or the parent of the entity acquiring control of BIOLASE agree to commit in writing, within sixty (60) days after receipt of such request, to continue to perform the specified BIOLASE activity, to otherwise agree to be bound by the provisions of this SECOND AGREEMENT, and to agree to commit in writing to duly and timely pay, perform and discharge all of the obligations of BIOLASE under this SECOND AGREEMENT.

P&G may elect to terminate this SECOND AGREEMENT and a determination pursuant to Exhibit E will be made of the PURCHASE PRICE of the BIOLASE PATENTS licensed to P&G in the PRIMARY P&G FIELD OF USE under this SECOND AGREEMENT, which patents are listed on Exhibit A, and within fifteen (15) days following such PURCHASE PRICE determination P&G will make the further election, in writing, either to (a) purchase BIOLASE PATENTS, or (b) rescind its election to purchase BIOLASE PATENTS. If P&G elects to purchase the BIOLASE PATENTS, the SECOND AGREEMENT will terminate except for certain surviving obligations. P&G will be obligated to grant back limited rights to BIOLASE under the acquired BIOLASE PATENTS if such patents cover products outside the P&G FIELD OF USE.

Change in Control. For purposes of this SECOND AGREEMENT, a “CHANGE IN CONTROL” of BIOLASE will be deemed to have occurred in the event of (i) a merger, combination, reorganization or consolidation of BIOLASE with or into another corporation with respect to which less than a majority of the outstanding voting power of the surviving or consolidated corporation is held by shareholders of BIOLASE immediately prior to such event, (ii) the sale of all or substantially all of the properties and assets of BIOLASE and its subsidiaries, or (iii) the accumulation or acquisition by any individual, firm, corporation, or entity (other than any profit sharing or other employee benefit plan of BIOLASE or any Affiliate, or any employee or group of employees or former officers an/or directors of BIOLASE or its Affiliates) of beneficial ownership, directly or indirectly, of securities of BIOLASE representing more than fifty percent (50%) of the combined voting power of BIOLASE’s then outstanding voting securities.

Right of First Negotiation. If BIOLASE elects to seek a buyer for any BIOLASE PATENT set out in Exhibit A licensed hereunder to P&G, P&G will have **** right of first negotiation with respect to a potential purchase by P&G of such BIOLASE PATENT. In the event the PARTIES do not enter into a binding agreement with respect to such purchase within the **** or in the event BIOLASE receives a binding unsolicited offer, BIOLASE will have sole discretion to pursue offers and sale to other parties. It is understood that BIOLASE may license, or may have licensed, other parties in fields outside of fields licensed to P&G under this SECOND AGREEMENT, and that BIOLASE PATENTS may be so encumbered when first offered to P&G under this Section 11.5.

Termination Not Sole Remedy. Termination is not the sole remedy under this SECOND AGREEMENT and, whether or not termination is affected, all other remedies will remain available except as agreed to otherwise herein.

Survival of Certain Obligations. Section 12 will survive any termination, in whole or in part, of this SECOND AGREEMENT. The termination of this SECOND AGREEMENT will not relieve either PARTY of any liability it may have to the other PARTY arising out of or relating to acts or omissions occurring prior to termination.

The signing date “SIGNING DATE” of this SECOND AGREEMENT will be on the day of execution of the last to sign this SECOND AGREEMENT.

During the term of this SECOND AGREEMENT, both PARTIES may be exposed to certain information of the other PARTY, not generally known to the public and related to this SECOND AGREEMENT, which has been identified by the disclosing PARTY (the “DISCLOSING PARTY”) at the time of disclosure as being confidential by means of an appropriate marking, or, if disclosed orally or visually, will be confirmed in writing as confidential within **** of the oral or visual disclosure (collectively the “CONFIDENTIAL INFORMATION”). The PARTY receiving the CONFIDENTIAL INFORMATION (the “RECEIVING PARTY”) will keep the DISCLOSING PARTY’s CONFIDENTIAL INFORMATION in confidence for a period of **** from disclosure, using measures no less protective than the RECEIVING PARTY takes to protect its own CONFIDENTIAL INFORMATION of like nature, which in no event will be less than a reasonable standard of care.

Exceptions. The obligations in Section 12.1 will not preclude the RECEIVING PARTY from using or disclosing the same or similar information which may be the same as the DISCLOSING PARTY’s CONFIDENTIAL INFORMATION to the extent that such same or similar information (i) was or later becomes, through no act or omission on the part of the RECEIVING PARTY, generally available to or available to the public; (ii) was rightfully in the possession of the RECEIVING PARTY at the time of disclosure by the DISCLOSING PARTY, as established by relevant documentary evidence, without restriction as to use or disclosure; (iii) is hereafter acquired by the RECEIVING PARTY from a third party who, in providing such information, does not breach an obligation or confidence of the DISCLOSING PARTY and provides such information without restriction as to use or disclosure; or (vi) is independently conceived, created, or developed by the RECEIVING PARTY without use of or access to the DISCLOSING PARTY’s CONFIDENTIAL INFORMATION, as established by relevant documentary evidence. The provisions of Section 12 will not restrict a PARTY from disclosing the other PARTY’s CONFIDENTIAL INFORMATION to the extent required by any law or regulation; provided that the PARTY required to make such a disclosure uses reasonable efforts to give the other PARTY reasonable advance notice of such required disclosure in order to enable the other PARTY to prevent or limit such disclosure.

Trade Secrets. If the DISCLOSING PARTY provides to the RECEIVING PARTY CONFIDENTIAL INFORMATION which includes a trade secret, the CONFIDENTIAL INFORMATION limited to the trade secret shall be kept confidential by the RECEIVING PARTY perpetually unless the trade secret falls under one of the exceptions of section 12.2.

Notice and Negotiation. In the event of any dispute or disagreement arising out of this SECOND AGREEMENT, the PARTIES will attempt to resolve the matter by submitting it for resolution to the President or Chief Executive Officer of BIOLASE and the appropriate Vice President or General Manager of Research and Development of P&G. If these representatives are unable to resolve such dispute to the satisfaction of both BIOLASE and P&G within **** after the date on which the dispute was submitted to such representative(s), the dispute will be subject to the process described in Section 13.2 below.

Arbitration. P&G and BIOLASE will attempt to settle any claim, controversy or deadlock through consultation and negotiation in good faith and a spirit of mutual cooperation pursuant to Section 13.1 above. If such attempt fails, the PARTIES agree to submit to binding arbitration that will be governed by the rules and procedures of the American Arbitration Association, with the requirement that the decision being issued by a written decision and opinion signed by an independent three-person panel. Such arbitration will take place in the State of New York. Judgment upon the award of the arbitrator may be entered in any court having jurisdiction thereof. In the event the arbitration involves a claimed material breach of the SECOND AGREEMENT, the alleged breach will become a MATERIAL BREACH upon a decision by the arbitration panel that a material breach has occurred.

By BIOLASE. From and after the EFFECTIVE DATE of this SECOND AGREEMENT, BIOLASE will indemnify, defend and hold harmless P&G and its AFFILIATES and licensees and their respective directors, officers, shareholders, partners, attorneys, accountants, and employees and any agents of the foregoing and any heirs, executors, successors and assigns of any of the foregoing (the “P&G INDEMNIFIED PARTIES”) from, against and in respect of any damages, losses, charges, obligations, liabilities, actions, interest, penalties and reasonable costs and expenses (including, without limitation, reasonable attorneys’ and experts’ fees and expenses incurred to enforce successfully the terms of this SECOND AGREEMENT, “P&G LOSSES AND EXPENSES”)) imposed on, sustained, incurred or suffered by any of the P&G INDEMNIFIED PARTIES relating to, arising from or otherwise in respect of (i) any breach of, or inaccuracy in, a representation or warranty of BIOLASE hereunder, or (ii) a breach of a covenant or other agreement of BIOLASE hereunder, or (iii) any action brought by a third party against a P&G INDEMNIFIED PARTY arising from or related to BIOLASE’s manufacturing, sale, marketing, distribution, or other exploitation of a product covered by the BIOLASE PATENTS, BIOLASE TECHNOLOGY, and/or P&G IP; provided, however, that BIOLASE will have no obligation to indemnify P&G for any P&G LOSSES AND EXPENSES for which indemnification is sought if (i) such P&G LOSSES AND EXPENSES were also caused by, relate to or involve a breach of, or inaccuracy in, any covenant, obligation, representation or warranty of P&G provided to BIOLASE in this SECOND AGREEMENT or (ii) such P&G LOSSES AND EXPENSES result from or arise out of a material action or omission of P&G.

Third Party Claims. The “INDEMNIFIED PARTIES” will mean the BIOLASE INDEMNIFIED PARTIES and the P&G INDEMNIFIED PARTIES. If a claim by a third party is made against an INDEMNIFIED PARTY hereunder, and if such INDEMNIFIED PARTY intends to seek indemnity with respect thereto under this Section 14, such INDEMNIFIED PARTY will promptly notify BIOLASE, in the case of a P&G INDEMNIFIED PARTY, or P&G, in the case of a BIOLASE INDEMNIFIED PARTY (such PARTY to be notified, the “INDEMNIFYING PARTY”) in writing of such claims setting forth such claims in reasonable detail, provided that failure of such INDEMNIFIED PARTY to give prompt notice as provided herein will not relieve the INDEMNIFYING PARTY of any of its obligations hereunder, except to the extent that the INDEMNIFYING PARTY is materially prejudiced by such failure. The INDEMNIFYING PARTY will have **** after receipt of such notice to undertake, through counsel of its own choosing, subject to the reasonable approval of such INDEMNIFIED PARTY, and at the INDEMNIFYING PARTY’S expense, the settlement or defense thereof, and the INDEMNIFIED PARTY will cooperate with it in connection therewith; provided, however, that the INDEMNIFIED PARTY may participate in such settlement or defense through counsel chosen by such INDEMNIFIED PARTY, provided that the fees and expenses of such counsel will be borne by such INDEMNIFIED PARTY. If the INDEMNIFYING PARTY will assume the defense of a claim, it will not settle such claim without the prior written consent of the INDEMNIFIED PARTY, (a) unless such settlement includes as an unconditional term thereof the giving by the claimant of a release of the INDEMNIFIED

PARTY from all liability with respect to such claim or (b) if such settlement involves the imposition of equitable remedies or the imposition of any material obligations on such INDEMNIFIED PARTY other than financial obligations for which such INDEMNIFIED PARTY will be indemnified hereunder. If the INDEMNIFYING PARTY will assume the defense of a claim, the fees of any separate counsel retained by the INDEMNIFIED PARTY will be borne by such INDEMNIFIED PARTY unless there exists a conflict between them as to their respective legal defenses (other than one that is of a monetary nature), in which case the INDEMNIFIED PARTY will be entitled to retain separate counsel, the reasonable fees and expenses of which will be reimbursed by the INDEMNIFYING PARTY. If the INDEMNIFYING PARTY does not notify the INDEMNIFIED PARTY within **** after the receipt of the INDEMNIFIED PARTY’s notice of a claim of indemnity hereunder that it elects to undertake the defense thereof, the INDEMNIFIED PARTY will have the right to contest, settle or compromise the claim but will not thereby waive any right to indemnity therefore pursuant to this SECOND AGREEMENT. The indemnification provisions set forth in this Section 14 are the sole and exclusive means of recovery of money damages with respect to the matters covered herein, except for fraud.

Limitation on Losses and Expenses. Notwithstanding anything to the contrary contained herein, no INDEMNIFYING PARTY hereunder will be liable (including liability for negligence or other tortious act or omission) for (a) any loss of profit, loss of contract or loss of goodwill incurred by any INDEMNIFIED PARTY; or (b) any punitive, indirect or consequential damages incurred by any INDEMNIFIED PARTY pursuant to this SECOND AGREEMENT (it being understood that any damages described in this Section 14.4 owed by any INDEMNIFIED PARTY to any third party will be considered direct damages, not subject to this Section 14.4).

MISCELLANEOUS

Certain Injunctive Relief. Due to the important confidentiality concerns of the PARTIES, and for other reasons, the PARTIES will be irreparably damaged in the event that the provisions of Sections 4.6.1.1; 4.6.1.2; and 12 are not specifically enforced. In the event of a breach or threatened breach of the terms, covenants and/or conditions of either such Section 12 by any of the PARTIES hereto, the other party will, in addition to any other remedies it may have, be entitled to a temporary or permanent injunction, without showing any actual damage, and/or a decree for specific performance, in accordance with the provisions of such Section 12.

Noncompete. Subject to Section 15.2.1 and 15.2.2 of this Non-Compete Section 15.2, BIOLASE by itself or through third parties will not directly or indirectly enter into the research, development, prototyping, testing, manufacture, supply, marketing, distribution, sale, promotion, or commercialization of any compounds, materials, or products in the P&G FIELDS OF USE, including the PRIMARY P&G FIELD OF USE, and the P&G RETAINED FIELD except as provided herein via the BIOLASE FIELD OF USE by: (i) developing, prototyping, conducting research on, manufacturing, supplying, marketing, selling or distributing any such products or products competing with such products to any third party other than P&G; (ii) licensing any intellectual property to any third party other than P&G for use in connection with the research, development, prototyping, testing, manufacture, supply, marketing, distribution, sale, promotion, or commercialization any such compounds, materials, or products; (iii) consulting with, supplying compounds, materials, or products to, cooperating with or providing services to, any third party other than P&G with respect to the research, development, prototyping, testing, manufacture, supply, marketing, distribution, sale, promotion, or commercialization of any such compounds, materials, or products; or (iv) investing in any third party other than P&G, that engages in the research, development, prototyping, testing, manufacture, supply, marketing, distribution, sale, promotion, or commercialization of such products, (collectively, the “RESTRICTED BUSINESS”); provided, however, that this restriction will not apply to BIOLASE directly acquiring a non-controlling ownership interest of less than fifty percent (50%) of the equity of a public or private company that engages in a RESTRICTED BUSINESS if BIOLASE acquires such equity stake in such company primarily in exchange for obtaining rights (either via an outright assignment or a license) or access to technology owned by such company and that is unrelated to the RESTRICTED BUSINESS and such company’s market cap does not exceed **** ($****). In addition, BIOLASE may acquire a less than **** equity stake in any publicly traded or private company that derives less than **** of its revenues from the RESTRICTED BUSINESS.

The time periods of this Non-Compete Section will apply to and be effective for/during the time period that P&G has license rights and/or BIOLASE has license rights, or options thereto (excluding the categories which revert back to BIOLASE) notwithstanding the time limitations provided in section 15.2.2. The terms of Sections 15.2 and 15.2.1 will not apply to (i) categories which have reverted back to BIOLASE from the P&G FIELDS OF USE, (ii) the DENTAL TRAY Field in the event that P&G does not exercise its option, and (iii) the BIOLASE RETAINED FIELD.

The time periods of section 15.2.1 will not extend beyond three years from the EFFECTIVE DATE of this SECOND AGREEMENT for the P&G FIELDS OF USE and will not extend beyond five years from the EFFECTIVE DATE of this SECOND AGREEMENT for the PRIMARY P&G FIELD OF USE and the P&G RETAINED FIELD.
