2.4 Have Made Restrictions and Exception. The licenses granted in Sections 2.1 and 2.2 shall not permit Trinity to have Licensed
Products made by any Third Party, with the following exceptions: (a) at any time during the Term with respect to HIV Products sold by Trinity for final sale in any country that is a member of the Economic Community of West African States as at

Trinity may subcontract the manufacture of any HIV Products to any contract manufacturer. Trinity shall execute a written sublicense with any contract manufacturer which shall be subject to Trinitys rights and obligations under the terms of
this Agreement, and shall provide a copy of the sublicense agreement to Inverness within 30 days after execution. Trinity shall ensure that any such sublicense agreement contains terms that are at least as protective of the Current Patents,
Charlton Patents and Future Patents as the terms set forth herein, and contains no terms that would be in violation of the license grant set forth in this Agreement, and, with respect to such sublicense agreement, shall cause any contract
manufacturer to assume and perform all of the covenants and obligations of Trinity to Inverness contained in this Agreement, to the extent applicable to such contract manufacturers exercise of its sublicense rights. Upon termination of this
Agreement as provided herein, any sublicense agreement shall thereupon automatically terminate, and Trinity shall cause any sublicense agreements to provide for such termination. Except as set forth above or in Section 11, Trinity shall
otherwise have no right to sublicense, transfer or assign any right or license granted by Section 2.1 or 2.2, and any purported sublicense, transfer or assignment shall be void.

2.5 Use of Distributors. The restrictions in Section 2.1, 2.2 and 2.4 on transfer and sub-licensing of license rights shall not
prohibit Trinity or Trinity Subsidiaries from distributing Licensed Products under a Trinity Mark through any distributor that is granted only the right to offer for sale and sell Licensed Products under such Trinity Mark where such products and
their packaging are not modified by the distributor from the form in which the products and packaging are shipped by Trinity or the Trinity Subsidiary, nor shall such restrictions prevent third parties that purchase HIV Products from Trinity
(including Trinity Subsidiaries) for re-sale as Re- Branded HIV Products from selling such Re-Branded HIV Products through distributors selling such Re-Branded HIV Products under the same packaging and Third Party Mark (any such distributor a
Distributor). Inverness acknowledges that Distributors include distributors that sell Licensed Products on commission as well as distributors that purchase Licensed Products from Trinity (including Trinity Subsidiaries) for resale for
the distributors own account.

2.6 Section 365(n). The licenses granted under this Section 2 shall be treated as
licenses of rights to intellectual property (as defined in Section 101(56) of Title 11 of the United States Code, as amended (the Bankruptcy Code)) for purposes of Section 365(n) of the Bankruptcy Code. The parties

4.3 Royalty Conditions. The above royalties shall be payable on a Licensed Product-by-Licensed Product basis. The royalty term for each
Licensed Product shall continue until the date when the last to expire of the Current Patents, Charlton Patents or Future Patents (if any) covering such Licensed Product expires. In the event that more than one Current Patent, Charlton Patent or
Future Patent (if any) is applicable to any Licensed Product subject to royalties under this Section 4, then only one royalty shall be paid to Inverness in respect of such Licensed Product. Furthermore, in no event shall more than one royalty
be due hereunder with respect to any Licensed Product.

Execution Version

prime interest rate as quoted by the head office of Citibank, N.A., New York, at the close of banking on such date, or on the first business day thereafter if
such date falls on a non-business day. If such interest rate exceeds the maximum legal rate in the jurisdiction where a claim therefor is being asserted, the interest rate shall be reduced to such maximum legal rate.

4.5 Underpayments. In the event an audit under the provisions of Section 5.6 identifies an underpayment of royalties by Trinity,
Trinity shall pay an amount equal to such underpayment within sixty days of Invernesss written request following such audit. Such amounts shall be subject to interest under the provisions of Section 4.4.

Section 5. Royalty Accruals, Records, Reports and Other Information.

5.1 Royalty Accrual. Royalties shall accrue when a Licensed Product is first sold or otherwise transferred for value by Trinity or a
Trinity Subsidiary to a Third Party (including, except as otherwise agreed in writing by Inverness, sold or otherwise transferred to Inverness or any Inverness Affiliate).

5.2 Currency Conversion. Trinity shall pay all royalties and other payments due hereunder in United States dollars. All royalties for an
accounting period in respect of Net Sales billed and received in other currencies shall be converted into United States dollars at the exchange rate for bank transfers from such currency to United States dollars as quoted by the head office of
Citibank, N.A., New York, at the close of banking on the last day of such accounting period (or the first business day thereafter if such last day shall be a non-business day).

5.3 Quarterly Report and Payment. Within thirty (30) days after the end of each calendar quarter during the Term, Trinity shall
furnish to Inverness a written report containing the information specified in Section 5.4 and shall pay to Inverness all royalties accrued hereunder for such calendar quarter.

5.4 Content of Reports. Trinitys written reports shall be certified by an officer of Trinity and shall contain for each type of
Licensed Product upon which a royalty has accrued (i) a description of said Licensed Product, (ii) the quantity of such Licensed Product sold or otherwise transferred during the accounting period, (iii) the price at which the Licensed
Product was sold, (iv) the region (LDC Country or other than LDC Country) in which it was sold, (v) Net Sales attributable to each of the Licensed Products during such accounting period and (vi) the calculation of royalties and the
total royalties due Inverness. In the event no royalties are due, Trinitys report shall so state.

5.5 Verification of Licensed
Products. For the purpose of determining whether products offered for sale or otherwise marketed by Trinity (including Trinity Subsidiaries) and not identified by Trinity as Licensed Products in the reports delivered pursuant to Section 5.4
should be considered Licensed Products, Trinity shall, within thirty (30) days of a written request by Inverness for confirmation that any such product is not a Licensed Product (such request to include the basis on which Inverness believes the
product is a Licensed Product), provide to an independent outside patent attorney selected by Inverness and reasonably acceptable to Trinity, which patent attorney shall at Trinitys request enter into a confidentiality agreement reasonably



7

Execution Version

acceptable to Trinity as a condition precedent to receiving such materials containing terms consistent with the provisions of Section 9, evidence that
the product does not in fact infringe any Current Patent, Charlton Patent or any Future Patent. Such patent attorney shall only disclose his/her conclusions regarding whether the products that are the subject of Invernesss request should be
characterized as Licensed Products, including the basis for such conclusion, but shall not disclose the materials provided by Trinity without Trinitys prior written consent, except to the extent that the disclosure is necessary to provide the
basis for the conclusion regarding infringement. Such patent attorney shall simultaneously provide Trinity and Inverness with a copy of any such conclusions.

5.6 Records and Audit. Trinity (including Trinity Subsidiaries) shall establish and maintain complete and accurate records in sufficient
detail to permit the determination of Licensed Products subject to this Agreement, the royalties due Inverness, and the accuracy of the information in Trinitys written reports.

(a) Such records shall include, but not be limited to, detailed records supporting the information provided under Section 5.4 which, if
applicable, shall be kept in accordance with generally accepted accounting principles (GAAP).

(b) Such records shall be kept
for two years following the reporting period to which they pertain.

(c) Upon Invernesss written request for an audit, Trinity will
permit an independent certified public accounting firm of recognized standing, selected by Inverness and reasonably acceptable to Trinity, together with a limited number of such independent legal and technical support personnel as Inverness deems
necessary which personnel are reasonably acceptable to Trinity, to examine, during ordinary business hours, records, materials, and manufacturing processes of Trinity for the purpose of verifying the accuracy of the royalty reports and payments by
Trinity. The audit shall be limited to pertinent books and records for any calendar year ending not more than twenty-four (24) months prior to the date of such request. Such audit right shall not be exercised more than once in any calendar
year. The accounting firm and legal and technical firm employees shall sign confidentiality agreements reasonably acceptable to Trinity as a condition precedent to their audit, which shall contain terms consistent with the provisions of
Section 9. Trinity may designate competitively sensitive information which such auditor may not disclose to Inverness; provided, however, that such designation shall not encompass the auditors conclusions. The accounting
firm shall disclose to Inverness only whether the royalty reports are correct or incorrect and the specific details concerning any discrepancies.

(d) Such requested audit shall be restricted to an audit of those records, materials, and manufacturing processes reasonably related to
Licensed Products, Current Patents, Charlton Patents and Future Patents (if any). Accordingly, such records and materials shall include the records specified in this Section 5.6 and other general financial information to the extent necessary to
provide a cross-check for the amount of royalties reported. Such financial information shall include, but not be limited to, records on the total revenue derived from Licensed Products for the accounting period with documentation supporting the
non-payment of royalty on that portion of the total revenue which Trinity claims should not be included in Net Sales, records of sales of products that were bundled with Licensed Products, and records pertaining to Licensed Products that were
transferred for below fair market value.

Execution Version

(e) Trinity shall provide its full cooperation in such audit.

(f) Inverness shall pay the cost of such audit. However, in the event that the audit reveals underpayment of five percent (5%) or more of
the royalties which should have been paid for the accounting periods being audited, then Trinity shall pay for the cost of such audit.

Section 6. Option To Distribute.

6.1Grant of Option. Trinity hereby grants Inverness the option to serve as the exclusive distributor of the Trinity HIV Product in the
Retail Field in the United States, subject to the parties negotiation of a mutually acceptable distribution agreement (the Option). Inverness shall exercise the Option by delivering to Trinity written notice of its intention to
exercise the Option during the period beginning on the Effective Date and ending on the six-month anniversary of the Effective Date (the Option Period), after which such Option shall expire. In the event that Inverness exercises the
Option within the Option Period, Trinity shall use its best efforts to negotiate in good faith with Inverness the terms of a mutually acceptable distribution agreement. Trinity shall negotiate with Inverness for not less than three (3) months
after exercise of the Option (unless the parties conclude an agreement within that period). During the Option Period and such negotiation period, Trinity shall not appoint any Third Party to distribute the Trinity HIV Product in the United States.
If the parties are unable to reach mutually agreeable terms within the three month period, the parties hereby agree to submit the matter to a third party mediator, and to work with such mediator in good faith to arrive at a resolution for a period
of up to 30 days from appointment of the mediator.

6.2 Inverness Credit. If Inverness exercises the Option and the parties enter
into an agreement within 9 months after the Effective Date pursuant to which (a) Trinity appoints Inverness as the exclusive distributor of the Trinity HIV Product in the Retail Field in the United States (that is, neither Trinity nor any
Trinity Subsidiary nor any Third Party may distribute the Trinity HIV Product in the Retail Field in the United States); and (b) Inverness agrees not to distribute or sell any other HIV diagnostic tests in the Retail Field in the United States
during the term of such agreement, then Trinity agrees that Inverness may withhold and retain 20% of the amounts otherwise due to Trinity in each payment period under such distribution agreement, until Inverness has withheld and retained a total of
$1 million in such payments.

Section 7. Term of Agreement; Termination.

7.1Term. The term of this Agreement shall be from the Effective Date hereof until the last to expire of the Current Patents, Charlton
Patents or Future Patents, unless it is sooner terminated in accordance with this Section 7 (the Term).

7.3Termination for Breach. If either party shall breach any material provision of this Agreement, and such failure has not been cured
within sixty (60) days after written notice from the non-breaching party specifying the nature of such failure, the non-breaching party shall have the right to terminate this Agreement on written notice to the breaching party.

7.4Termination on Insolvency. If any party enters any involuntary bankruptcy, insolvency, receivership, dissolution, or similar
proceeding which continues for thirty (30) days from filing, or any voluntary bankruptcy, insolvency, receivership, dissolution, liquidation, or similar proceeding, or otherwise fails to be able to pay its debts as and when they fall due, the
other party may terminate this Agreement on written notice to such party.

7.5Termination for Patent Challenge. If Trinity or any
Trinity Subsidiary shall challenge the validity of any of the Current Patents, Charlton Patents or Future Patents before any court or governmental agency, then this Agreement and the licenses granted herein shall terminate immediately without
notice.

7.6Effect of Termination. No termination of this Agreement shall relieve either party of any obligation or liability
accrued hereunder prior to such termination (including unpaid royalties), or rescind or give rise to any right to rescind anything done by Trinity or any payments made or other consideration given to Inverness hereunder prior to the time such
termination becomes effective, and such termination shall not affect in any manner any rights of either party arising under this Agreement prior to such termination. The provisions of Sections 5 (with respect to sales made through the effective date
of termination), 7.6, 8, 9, 10, 11 and 12.3-12.8 shall survive any termination or expiration of this Agreement in accordance with their respective terms.

Section 8. Warranty, Disclaimers, Indemnification, Insurance and Limitation of Liability.

8.1 Mutual Representations and Warranties: Each Party represents and warrants that:

(a) it has full corporate power and authority to enter into this Agreement and to carry out the provisions hereof;

(b) this Agreement constitutes a valid and binding agreement, enforceable against it in accordance with its terms; and

(c) the execution, delivery and performance of this Agreement does not violate any law, statute, ordinance, rule or regulation, or any
judgment, injunction, order, writ or decree of any court, arbitrator, or governmental entity by which such Party or any of its assets or properties may be bound, and does not conflict with or result in the breach or termination of any license,
permit, approval, consent, franchise, lease, contract, or other instrument or agreement by which such party is bound.

Execution Version

8.2 Inverness Warranty. Inverness represents and warrants that:

(a) it has the full right and power to grant the licenses set forth in Section 2 and Section 3, and that there are no outstanding
agreements, assignments, or encumbrances inconsistent with the provisions of such licenses or with any other provisions of this Agreement;

(b) as at the Effective Date, the Current Patents and Charlton Patents include all Patent Rights owned or Controlled by Inverness or Inverness
Affiliates that are used in, useful or necessary for the manufacture, use, sale or importation of Licensed Products, and Inverness and Inverness Affiliates have not taken any action to exclude from the Current Patents or Charlton Patents any such
Patent Rights; and

(c) to the best of the Invernesss knowledge, all Patent Rights licensed hereunder are valid and enforceable, and
all patents, if any, issuing on any of the pending patent applications of the Patent Rights will be valid and enforceable.

8.3
Disclaimer. Inverness does not represent or warrant that the Current Patents or Charlton Patents are applicable to any particular Licensed Product. Inverness also makes no other representations or warranties, express or implied, and hereby
disclaims the implied warranties of merchantability, fitness for a particular purpose or non-infringement of third party rights. Inverness disclaims and Trinity assumes any liability in respect of any infringement of patents or other rights of Third
Parties due to Trinitys operation under the license herein granted. Without limiting the disclaimer, Inverness specifically disclaims any representation, warranty or implication that the licenses granted hereby are sufficient for Trinity to
make, use, lease, import, sell and otherwise transfer Licensed Products.

8.4 Indemnification. Trinity shall indemnify, defend, and
hold harmless Inverness and its Affiliates and their directors, officers, employees and agents and their respective successors, heirs and assigns (the Indemnitees), against any liability, damage, loss, or expense (including reasonable
attorneys fees and expenses of litigation) incurred by or imposed upon any of the Indemnitees by any Third Party in connection with any claims, suits, actions, demands or judgments arising out of any theory of liability (including without
limitation actions in the form of tort, warranty, or strict liability and regardless of whether such action has any factual basis) concerning any product, process, or service that is made, used, or sold pursuant to the exercise by Trinity (including
Trinity Subsidiaries) of any right or license granted under this Agreement. To receive the benefit of indemnification the Indemnitees must (i) provide Trinity with prompt written notice within twenty (20) days of any claim, suit, action,
demand, or judgment for which indemnification is sought under this Agreement; (ii) cooperate fully with Trinity in such defense; and (iii) permit Trinity to conduct and control such defense and the disposition of such claim, suit, or
action (including all decisions relative to litigation, appeal, and settlement). Trinity agrees, at its own expense, to provide attorneys reasonably acceptable to Inverness to defend against any such claim. In the event that Inverness has rejected
Trinitys choices of counsel three (3) consecutive times, then Trinity, in its sole decision, shall select counsel acceptable to Trinity. Notwithstanding the provision of Section 8.4(iii), any Indemnitee shall have the right to retain
its own counsel, at the expense of Trinity, if representation of such Indemnitee by the counsel retained by Trinity would be inappropriate because of actual or potential differences in the interests of such Indemnitee and any other party represented
by such counsel. Trinity agrees to keep Inverness informed of the progress in the defense and disposition of such claim and to consult with Inverness with regard to any proposed settlement. Trinity shall



11

Execution Version

have no obligation to indemnify any Indemnitee in connection with any settlement made without Trinitys written consent. The foregoing indemnification
obligations shall not apply to the extent that a court of competent jurisdiction determines that applicable losses arose as a result of any Indemnitees negligence or intentional misconduct.

8.5Insurance. Trinity shall maintain insurance or self-insurance that is reasonably adequate to fulfill any potential obligation to the

DAMAGES RESULTING FROM LOSS OF USE, PROFITS, BUSINESS OR GOODWILL, WHETHER OR NOT THE PARTY ALLEGEDLY CAUSING THE DAMAGE HAS BEEN ADVISED OF THE POSSIBILITY THEREOF. THIS SECTION 8.6 SHALL NOT BE CONSTRUED TO LIMIT TRINITYS INDEMNIFICATION
OBLIGATIONS UNDER SECTION 8.4 HEREOF.

9.2Obligations. The Recipient shall: (a) not disclose the Disclosing Partys Confidential Information to third parties;

requesting disclosure of such Confidential Information; provided, that the Recipient provides prompt notice to the Disclosing Party and permits the Disclosing Party to contest or narrow such request for disclosure, and thereafter complies
with such subpoena or other process; or (v) was independently developed by the Recipient without reference to the Disclosing Partys Confidential Information.

Section 10. Patent Prosecution and Enforcement.

10.1Prosecution. Inverness and its Third Party licensors shall retain all right, in their absolute discretion, to control the
prosecution (or failure to prosecute) all Patent Rights included within the Current Patents, Charlton Patents and Future Patents. Neither party nor any of its Affiliates (including Inverness Subsidiaries) shall be required hereunder to file any
patent application, or to secure any patent or patent rights, or to maintain any patent in force, or to provide copies of patent applications to the other party or its Affiliates, or to disclose any inventions described or claimed in such patent
applications.

10.2Enforcement. Trinity shall promptly inform Inverness if and when it becomes aware of any Third Party
infringement of any of the Current Patents, Charlton Patents or any Future Patents. Inverness shall not have any obligation hereunder to institute any action or suit against third parties for infringement of any such Patent Rights or to defend any
action or suit brought by a Third Party which challenges or concerns the validity of any such Patent Rights. In addition, Trinity shall not have any right to institute any action or suit against third parties for infringement of any of the Current
Patents, Charlton Patents or any Future Patents.

Section 11. Assignment.

Trinity (including Trinity Subsidiaries) shall not assign, transfer or grant any right under any of the Current Patents, Charlton Patents or
Future Patents whether by agreement, operation of law (as in the case, by way of example, of a Change of Control as hereinafter defined; it being understood that the result of a Change of Control shall be determined in accordance with the following
sentence), or otherwise. If, after the Effective Date (a) Trinity is acquired by any Third Party, whether by stock acquisition, merger, consolidation or otherwise (including whether or not Trinity survives as a separate corporation or legal
entity as a result of such acquisition), (b) Trinity enters into a transaction in which the outstanding voting stock of Trinity is converted into cash, securities, or other property, or (c) any person, entity or group (within the meaning
of Section 13(d) or 14(d) of the Securities Exchange Act of 1934, as amended) acquires the majority of the voting power of the voting stock of Trinity, or (d) Trinity sells all or substantially all of the assets of Trinity (any of the
foregoing a Change of Control), then with automatic effect on occurrence of such Change of Control (the Change of Control Event) and without any action required of Inverness, the licenses granted in Sections 2.1 and 2.2 of this Agreement shall thenceforth be limited to Licensed Products which, at the time that Trinity first
entered into discussions with a Third Party leading to such Change of Control Event: (i) have been commercially released (that is, have been sold by Trinity or Trinity Subsidiaries as finished products to Third Parties in arms length
transactions); or (ii) have already been substantially developed, by employees employed by, or individuals engaged as subcontractors by, Trinity or a Trinity Subsidiary.
