OF



SONTRA MEDICAL CORPORATION (the Corporation)



ARTICLE 1Shareholders



1.1 Place of Meetings. All meetings of shareholders shall be held at such place within or without the State of Minnesota as may be designated from time to time by the Chairman of the Board (if any), the board
of directors of the Corporation (the Board of Directors) or the Chief Executive Officer or, if not so designated, at the principal office of the Corporation.



1.2 Annual Meeting. The annual meeting of shareholders for the election of directors and for the transaction of such
other business as may properly be brought before the meeting shall be held on a date to be fixed by the Chairman of the Board (if any), Board of Directors or the Chief Executive Officer (which date shall not be a legal holiday in the place where the
meeting is to be held) at the time and place to be fixed by the Chairman of the Board, the Board of Directors or the Chief Executive Officer and stated in the notice of the meeting.



1.3 Special Meetings. Special meetings of shareholders may be called for any purpose or purposes at any time by the
Chairman of the Board, the Chief Executive Officer, or a majority of the Board of Directors. Special meetings shall be held at such place, on such date and at such time as shall be fixed by the Board of Directors, or the person authorized to call
the meeting. Business transacted at any special meeting of shareholders shall be limited to matters relating to the purpose or purposes stated in the notice of meeting.



1.4 Notice of Meetings. Except as otherwise provided by law, written notice of each meeting of shareholders, whether
annual or special, shall be given not less than 10 nor more than 60 days before the date of the meeting to each shareholder entitled to vote at such meeting. The notices of all meetings shall state the place, date and hour of the meeting. The notice
of a special meeting shall state, in addition, the purpose or purposes for which the meeting is called. If mailed, notice is given when deposited in the United States mail, postage prepaid, directed to the shareholder at his or her address as it
appears on the records of the Corporation.



1.5 Voting
List. The officer who has charge of the stock ledger of the Corporation shall prepare, at least 10 days before every meeting of shareholders, a complete list of the shareholders entitled to vote at the meeting, arranged in alphabetical order,
and showing the address of each shareholder and the number of shares registered in the name of each shareholder. Such list shall be open to the examination of any shareholder, for any purpose germane to the meeting, during ordinary business hours,
for a period of at least 10 days prior to the meeting, either at a place within the metropolitan area of the city where the meeting is to be held, which place shall be specified in the notice of the meeting, or if not so specified, at the place
where the meeting is to be held. The list shall also be produced and kept at the time and place of the meeting during the whole time of the meeting, and may be inspected by any shareholder who is present. This list shall presumptively determine the
identity of the shareholders entitled to vote at the meeting and the number of shares held by each of them.



1.6 Quorum. Except as otherwise provided by law, the Articles of Incorporation or these By-Laws, the holders of a majority of the shares of the
capital stock of the Corporation issued and outstanding and entitled to vote at the meeting, present in person or represented by proxy, shall constitute a quorum for the transaction of business. Shares held by brokers which such brokers are
prohibited from voting (pursuant to their discretionary authority on behalf of beneficial owners of such shares who have not submitted a proxy with respect to such shares) on some or all of the matters before the shareholders, but which shares



1



---

would otherwise be entitled to vote at the meeting (Broker Non-Votes) shall be counted, for the purpose of determining the presence or absence of
a quorum, toward the total voting power of the shares of capital stock of the Corporation. If a quorum has been established for the purpose of conducting the meeting, a quorum shall be deemed to be present for the purpose of all votes to be
conducted at such meeting, provided that where a separate vote by a class or classes, or series thereof, is required, a majority of the voting power of the shares of such class or classes, or series, present in person or represented by proxy shall
constitute a quorum entitled to take action with respect to that vote on that matter. If a quorum shall fail to attend any meeting, the chairman of the meeting or the holders of a majority of the voting power of the shares of stock entitled to vote
who are present, in person or by proxy, may adjourn the meeting to another place, date, or time.



1.7 Adjournments. Any meeting of shareholders may be adjourned to any other time and to any other place at which a meeting of shareholders may be
held under these By-Laws by the shareholders present or represented at the meeting and entitled to vote, although less than a quorum, or, if no shareholder is present, by any officer entitled to preside at or to act as Secretary of such meeting. It
shall not be necessary to notify any shareholder of any adjournment of less than 120 days if the time and place of the adjourned meeting are announced at the meeting at which adjournment is taken, unless after the adjournment a new record date is
fixed for the adjourned meeting. At the adjourned meeting, the Corporation may transact any business which might have been transacted at the original meeting.



1.8 Voting and Proxies. At any meeting of the shareholders, each shareholder shall have one vote for each share of stock entitled to vote at
such meeting held of record by such shareholder, unless otherwise provided in the Articles of Incorporation. Each shareholder of record entitled to vote at a meeting of shareholders, or to express consent or dissent to corporate action in writing
without a meeting (to the extent not otherwise prohibited by the Articles of Incorporation or these By-laws), may vote or express such consent or dissent in person or may authorize another person or persons to vote or act for such shareholder by
written proxy executed by such shareholder or his or her authorized agent or by a transmission permitted by law and delivered to the Secretary of the Corporation. No such proxy shall be voted or acted upon after 11 months from the date of its
execution, unless the proxy expressly provides for a longer period. Any copy, facsimile telecommunication or other reliable reproduction of the writing or transmission created pursuant to this Section 1.8 may be substituted or used in lieu of the
original writing or transmission for any and all purposes for which the original writing or transmission could be used, provided that such copy, facsimile telecommunication or reproduction shall be a complete reproduction of the entire original
writing or transmission.



All voting, including on the election
of directors but excepting where otherwise required by law or the Articles of Incorporation, may take place via a voice vote. Any vote not taken by voice shall be taken by ballots, each of which shall state the name of the shareholder or proxy
voting and such other information as may be required under the procedure established for the meeting.



1.9 Action at Meeting. When a quorum is present at any meeting of shareholders, the holders of a majority of the stock present or represented and
entitled to vote on a matter (or if there are two or more classes of stock entitled to vote as separate classes, then in the case of each such class, the holders of a majority of the stock of that class present or represented and voting on such
matter) shall decide any matter to be voted upon by the shareholders at such meeting (other than the election of directors), except when a different vote is required by express provision of law or the Articles of Incorporation. Any election of
directors by the shareholders shall be determined by a plurality of the votes cast by the shareholders entitled to vote at such election, except as otherwise provided by the Articles of Incorporation. For the purposes of this paragraph, Broker
Non-Votes represented at the meeting but not permitted to vote on a particular matter shall not be counted, with respect to the vote on such matter, in the number of (a) votes cast, (b) votes cast affirmatively, or (c) votes cast negatively.



ARTICLE 2Directors



2.1 General Powers. The business and affairs of the Corporation shall
be managed by or under the direction of a Board of Directors, who may exercise all of the powers of the Corporation except as otherwise provided by law or the Articles of Incorporation. In the event of a vacancy in the Board of Directors, the
remaining directors, except as otherwise provided by law or the Articles of Incorporation, may exercise the powers of the full Board of Directors until the vacancy is filled.

---

2.2 Number; Election and Qualification. The number of directors which shall constitute the whole
Board of Directors shall be determined by resolution of the Board of Directors, but in no event shall be less than three. The number of directors may be decreased at any time and from time to time by a majority of the directors then in office, but
only to eliminate vacancies existing by reason of the death, resignation, removal or expiration of the term of one or more directors. The directors shall be elected at the annual meeting of shareholders (or, if so determined by the Board of
Directors pursuant to Section 10 hereof, at a special meeting of shareholders), by such shareholders as have the right to vote on such election. Directors need not be shareholders of the Corporation.



2.3 Terms in Office. Each director shall serve for a term ending on
the date of the annual meeting of shareholders following the annual meeting at which such director was elected.



2.4 Tenure. Notwithstanding any provisions to the contrary contained herein, each director shall hold office until his or her successor is elected
and qualified, or until his or her earlier death, resignation or removal.



2.5 Vacancies. Unless and until filled by the shareholders, any vacancy in the Board of Directors, however occurring, including a vacancy resulting from an enlargement thereof, may be filled by vote of a
majority of the directors then in office, although less than a quorum, or by a sole remaining director. A director elected to fill a vacancy shall be elected for the unexpired term of his or her predecessor in office, if any, and a director chosen
to fill a position resulting from an increase in the number of directors shall hold office until the next election of directors and until his or her successor is elected and qualified, or until his or her earlier death, resignation or removal.



2.6 Resignation. Any director may resign by delivering
his or her resignation in writing or by electronic transmission to the Corporation at its principal office or to the Chief Executive Officer or Secretary. Such resignation shall be effective upon receipt unless it is specified to be effective at
some other time or upon the happening of some other event.



2.7 Regular Meetings. Regular meetings of the Board of Directors may be held without notice at such time and place, either within or without the State of Minnesota, as shall be determined from time to time by the Board of Directors;
provided that any director who is absent when such a determination is made shall be given notice of the determination. Regular meetings of the Board of Directors shall be held at such place or places, on such date or dates, and at such time or times
as shall have been established by the Board of Directors and publicized among all directors. A notice of each regular meeting shall not be required.



2.8 Special Meetings. Special meetings of the Board of Directors may be held at any time and place, within or without the State of Minnesota,
designated in a call by those persons expressly authorized to call such meetings by the Minnesota Business Corporation Law.



2.9 Notice of Special Meetings. Notice of any special meeting of directors shall be given to each director by the Secretary or by the officer or
one of the directors calling the meeting. Notice shall be duly given to each director (i) by giving notice to such director in person or by telephone at least 48 hours in advance of the meeting, (ii) by telegram, cable, telecopy, electronic mail,
commercial delivery service, telex or similar means sent to his or her last known business or home address at least 48 hours in advance of the meeting, or (iii) by mailing written notice to his or her last known business or home address at least 72
hours in advance of the meeting. A notice or waiver of notice of a meeting of the Board of Directors need not specify the purposes of the meeting.



2.10 Meetings by Telephone Conference Calls. Directors or any members of any committee designated by the Board of Directors may participate in a
meeting of the Board of Directors or such committee by means of conference telephone or similar communications equipment by means of which all persons participating in the meeting can hear each other, and participation by such means shall be deemed
to constitute presence in person at such meeting.

2.11 Quorum. A majority of the total number of the whole Board of Directors shall constitute a
quorum at all meetings of the Board of Directors. In the event one or more of the directors shall be disqualified to vote at any meeting, then the required quorum shall be reduced by one for each such director so disqualified; provided, however,
that in no case shall less than one-third (1/3) of the total number of the whole Board of Directors constitute a quorum. In the absence of a quorum at any such meeting, a majority of the directors present may adjourn the meeting from time to time
without further notice other than announcement at the meeting, until a quorum shall be present.



2.12 Action at Meeting. At any meeting of the Board of Directors at which a quorum is present, the vote of a majority of those present shall be
sufficient to take any action, unless a different vote is specified by law, the Articles of Incorporation or these By-Laws.



2.13 Action by Written Consent. Any action required or permitted to be taken at any meeting of the Board of Directors or of any committee of the
Board of Directors may be taken without a meeting, if all members of the Board of Directors or committee, as the case may be, consent to such action in writing or by electronic transmission, and the writing or writings or electronic transmission or
transmissions are filed with the minutes of proceedings of the Board of Directors or committee. Such filing shall be in paper form if the minutes are maintained in paper form and shall be in electronic form if the minutes are maintained in
electronic form.



2.14 Removal. Unless otherwise
provided in the Articles of Incorporation, any one or more or all of the directors may be removed, only for cause, by the holders of at least seventy-five percent (75%) of the shares then entitled to vote at an election of directors.

Committee and a Compensation Committee in accordance with applicable rules and composition requirements as may be promulgated from time to time by the Securities and Exchange Commission, the National Association of Securities Dealers, any exchange
upon which securities of the Corporation are traded, or any governmental or regulatory body exercising authority over the Corporation. The Board of Directors may, by resolution passed by a majority of the whole Board, designate one or more
additional committees, each committee to consist of one or more of the directors of the Corporation. The Board of Directors may designate one or more directors as alternate members of any committee, who may replace any absent or disqualified member
at any meeting of such committee. In the absence or disqualification of a member of a committee, the member or members of such committee present at any meeting and not disqualified from voting, whether or not such member or members constitute a
quorum, may unanimously appoint another member of the Board of Directors to act at such meeting in the place of any such absent or disqualified member. Any such committee, to the extent provided in the resolution of the Board of Directors and
subject to the provisions of applicable law, shall have and may exercise all the powers and authority of the Board of Directors in the management of the business and affairs of the Corporation and may authorize the seal of the Corporation to be
affixed to all papers which may require it. Each such committee shall keep minutes and make such reports as the Board of Directors may from time to time request. Except as the Board of Directors may otherwise determine or as provided herein, any
committee may make rules for the conduct of its business, but unless otherwise provided by the directors or in such rules, its business shall be conducted as nearly as possible in the same manner as is provided in these By-Laws for the Board of
Directors. Adequate provisions shall be made for notice to members of all meeting of committees. One-third (1/3) of the members of any committee shall constitute a quorum unless the committee shall consist of one (1) or two (2) members, in which
event one (1) member shall constitute a quorum; and all matters shall be determined by a majority vote of the members present. Action may be taken by any committee without a meeting if all members thereof consent thereto in writing, and the writing
or writings are filed with the minutes of the proceedings of such committee.



2.16 Compensation of Directors. Directors may be paid such compensation for their services and such reimbursement for expenses of attendance at meetings as the Board of Directors may from time to time
determine. No such payment shall preclude any director from serving the Corporation or any of its parent or subsidiary corporations in any other capacity and receiving compensation for such service.

ARTICLE 7Indemnification



7.1 Mandatory Indemnification. The Corporation shall indemnify a person made or threatened to be made a party to a
proceeding by reason of the former or present official capacity of the person against judgments, penalties, fines, including, without limitation, excise taxes assessed against the person with respect to an employee benefit plan, settlements, and
reasonable expenses, including attorneys fees and disbursements, incurred by the person in connection with the proceeding, if, with respect to the acts or omissions of the person complained of in the proceeding, the person: (1) has not been
indemnified by another organization or employee benefit plan for the same judgments, penalties, fines, including, without limitation, excise taxes assessed against the person with respect to an employee benefit plan, settlements, and reasonable
expenses, including attorneys fees and disbursements, incurred by the person in connection with the proceeding with respect to the same acts or omissions; (2) acted in good faith; (3) received no improper personal benefit and section 302A.255
of the Minnesota Business Corporation Act, if applicable, has been satisfied; (4) in the case of a criminal proceeding, had no reasonable cause to believe the conduct was unlawful; and (5) in the case of acts or omissions occurring in the official
capacity described in Section 7.7(a) (1) or (2), reasonably believed that the conduct was in the best interests of the Corporation, or in the case of acts or omissions occurring in the official capacity described in Section 7.7(a) (3), reasonably
believed that the conduct was not opposed to the best interests of the Corporation. If the persons acts or omissions complained of in the proceeding relate to conduct as a director, officer, trustee, employee, or agent of an employee benefit
plan, the conduct is not considered to be opposed to the best interests of the Corporation if the person reasonably believed that the conduct was in the best interests of the participants or beneficiaries of the employee benefit plan. The
termination of a proceeding by judgment, order, settlement, conviction, or upon a plea of nolo contendere or its equivalent does not, of itself, establish that the person did not meet the criteria set forth in this Section 7.1.



7.2 Advances. If a person is made or threatened to be made a party to
a proceeding, the person is entitled, upon written request to the Corporation, to payment or reimbursement by the Corporation of reasonable expenses, including attorneys fees and disbursements, incurred by the person in advance of the final
disposition of the proceeding, (a) upon receipt by the Corporation of a written affirmation by the person of a good faith belief that the criteria for indemnification set forth in Section 7.1 have been satisfied and a written undertaking by the
person to repay all amounts so paid or reimbursed by the Corporation, if it is ultimately determined that the criteria for indemnification have not been satisfied, and (b) after a determination that the facts then known to those making the
determination would not preclude indemnification under this section. The written undertaking required by clause (a) is an unlimited general obligation of the person making it, but need not be secured and shall be accepted without reference to
financial ability to make the repayment.



7.3 Determination
of Eligibility. All determinations whether indemnification of a person is required because the criteria set forth in Section 7.1 have been satisfied and whether a person is entitled to payment or reimbursement of expenses in advance of the final
disposition of a proceeding as provided in Section 7.2 shall be made: (1) by the Board of Directors by a majority of a quorum, if the directors who are at the time parties to the proceeding are not counted for determining either a majority or the
presence of a quorum; (2) if a quorum under clause (1) cannot be obtained, by a majority of a committee of the Board of Directors, consisting solely of two or more directors not at the time parties to the proceeding, duly designated to act in the
matter by a majority of the full Board of Directors including directors who are parties; (3) if a determination is not made under clause (1) or (2), by special legal counsel, selected either by a majority of the Board of Directors or a committee by
vote pursuant to clause (1) or (2) or, if the requisite quorum of the full Board of Directors cannot be obtained and the committee cannot be established, by a majority of the full Board of Directors including directors who are parties; (4) if a
determination is not made under clauses (1) to (3), by the affirmative vote of the shareholders; or (5) if an adverse determination is made under clauses (1) to (4) or under paragraph (b), or if no determination is made under clauses (1) to (4) or
under paragraph (b) within 60 days after (i) the later to occur of the termination of a proceeding or a written request for indemnification to the Corporation or (ii) a written request for an advance of expenses, as the case may be, by a court in
the State of Minnesota, which may be



9



---

the same court in which the proceeding involving the persons liability took place, upon application of the person and any notice the court requires.
The person seeking indemnification or payment or reimbursement of expenses pursuant to this clause has the burden of establishing that the person is entitled to indemnification or payment or reimbursement of expenses.



With respect to a person who is not, and was not at the time of the acts or
omissions complained of in the proceedings, a director, officer, or person possessing, directly or indirectly, the power to direct or cause the direction of the management or policies of the Corporation, the determination whether indemnification of
this person is required because the criteria set forth in Section 7.1 have been satisfied and whether this person is entitled to payment or reimbursement of expenses in advance of the final disposition of a proceeding as provided in Section 7.2 may
be made by an annually appointed committee of the Board of Directors, having at least one member who is a director. The committee shall report at least annually to the Board of Directors concerning its actions.



7.4 Insurance. The Corporation may purchase and maintain insurance on
behalf of a person in that persons official capacity against any liability asserted against and incurred by the person in or arising from that capacity, whether or not the Corporation would have been required to indemnify the person against
the liability under the provisions of this Article 7.



7.5
Disclosure. If the Corporation indemnifies or advances expenses to a person in accordance with this Article 7 in connection with a proceeding by or on behalf of the Corporation, the Corporation shall report to the shareholders in writing the
amount of the indemnification or advance and to whom and on whose behalf it was paid not later than the next meeting of shareholders.



7.6 Indemnification of Other Persons. Nothing in this section shall be construed to limit the power of the Corporation to indemnify persons other
than a director, officer, employee, or member of a committee of the Board of Directors of the Corporation by contract or otherwise.



7.7 Definitions. For purposes of this Article 7, the terms defined in this Article 7 have the following meanings given them.



(a) Official capacity means (1) with respect to a director, the
position of director in the Corporation, (2) with respect to a person other than a director, the elective or appointive office or position held by an officer, member of a committee of the Board of Directors, or the employment relationship undertaken
by an employee of the Corporation, and (3) with respect to a director, officer, or employee of the Corporation who, while a director, officer, or employee of the Corporation, is or was serving at the request of the Corporation or whose duties in
that position involve or involved service as a director, officer, partner, trustee, employee, or agent of another organization or employee benefit plan, the position of that person as a director, officer, partner, trustee, employee, or agent, as the
case may be, of the other organization or employee benefit plan.



(b) Proceeding means a threatened, pending, or completed civil, criminal, administrative, arbitration, or investigative proceeding, including a proceeding by or in the right of the Corporation.



(c) Special legal counsel means counsel who has not represented
