PROXY STATEMENT FOR THE GI DYNAMICS

2018 ANNUAL MEETING OF STOCKHOLDERS TO BE HELD ON MAY 24, 2018 EDT

This proxy statement and the enclosed proxy card and CDI Voting Instruction Form are being mailed to stockholders and CDI holders on or about May     , 2018 and are furnished in connection with the solicitation of proxies by the Board of Directors of GI Dynamics, Inc. (“GI Dynamics”, “we”, “us”, or the “Company”) for use at an annual meeting of stockholders (the “Annual Meeting”) to be held on May 24, 2018, at 6:00 p.m., United States Eastern Daylight Time, (which is on May 25, 2018 at 8:00 a.m., Australian Eastern Standard Time) at the offices of Mintz, Levin, Cohn, Ferris, Glovsky and Popeo, P.C., One Financial Center, Boston, MA 02111, and at any adjournments or postponements thereof.

IMPORTANT: To ensure that your shares of common stock are represented at the Annual Meeting, please vote your shares of common stock (or, for CDI holders, direct CDN to vote your CDIs) via the Internet or by marking, signing, dating, and returning the enclosed proxy card or CDI Voting Instruction Form to the address specified. If you attend the Annual Meeting, you may choose to vote in person even if you have previously voted your shares of common stock, except that CDI holders may only instruct CDN to vote on their behalf by completing and signing the CDI Voting Instruction Form or voting online at www.linkmarketservices.com.au and may not vote in person.

IMPORTANT INFORMATION ABOUT THE ANNUAL MEETING AND VOTING

This proxy statement summarizes the information you need to know to vote at the Annual Meeting. You do not need to attend the Annual Meeting to vote your shares of common stock or CDIs. Instead, if you hold shares of common stock you may vote your shares of common stock by marking, signing, dating and returning the enclosed proxy card. If you hold CDIs, you may vote your CDIs by signing and returning the enclosed CDI Voting Instruction Form.

Why is the Company Soliciting My Proxy?

The board of directors of GI Dynamics is soliciting your proxy to vote at the Annual Meeting to be held on Thursday, May 24, 2018 at 6:00 p.m., U.S. Eastern Daylight Time (which is 8:00 a.m. on Friday, May 25, 2018, Australian Eastern Standard Time) at the offices of Mintz Levin, One Financial Center, Boston, MA 02111 and any adjournments of the Annual Meeting. The proxy statement along with the accompanying Notice of 2018 Annual Meeting of Stockholders summarizes the purposes of the Annual Meeting and the information you need to know to vote at the Annual Meeting.

If you held shares of our common stock at 4:30 p.m. on March 31, 2018 Australian Eastern Standard Time (which is 2:30 a.m. on March 31, 2018 U.S. Eastern Daylight Time) (the “Record Date”), you are invited to attend the Annual Meeting and vote on the proposals described in this proxy statement. Those persons holding CDIs are entitled to receive notice of and to attend the Annual Meeting and may instruct CDN to vote at the Annual Meeting by following the instructions on the CDI Voting Instruction Form or by voting online at www.linkmarketservices.com.au.

We have sent you this proxy statement, the Notice of 2018 Annual Meeting of Stockholders, the proxy card, CDI Voting Instruction Form and a copy of our Annual Report because you owned shares of GI Dynamics, Inc.’s common stock or CDIs on the Record Date. The Company intends to commence distribution of the proxy materials to stockholders on or about May     , 2018.

Who Can Vote?

If you were a holder of GI Dynamics common stock, either as a stockholder of record or as the beneficial owner of shares held in street name as of 4:30 p.m. on March 31, 2018 Australian Eastern Standard Time (which is 2:30 a.m. on March 31, 2018 U.S. Eastern Daylight Time), the Record Date for the Annual Meeting, you may vote your shares at the Annual Meeting. As of the Record Date, there were 12,331,101 shares of our common stock outstanding and entitled to vote (equivalent to 616,555,050 CDIs assuming all shares of common stock were converted into CDIs on the Record Date). Our common stock is our only class of voting stock. Each stockholder has one vote for each share of common stock held as of the Record Date. Each CDI holder is entitled to direct CDN to vote one vote for every fifty (50) CDIs held by such holder. As summarized below, there are some distinctions between shares held of record and those owned beneficially and held in street name.

You do not need to attend the Annual Meeting to vote your shares (or shares underlying your CDIs). Shares represented by valid proxies or, for CDI holders, by valid CDI Voting Instruction Forms, received in time for the Annual Meeting and not revoked prior to the Annual Meeting, will be voted at the Annual Meeting. For instructions on how to change or revoke your proxy, see “May I Change My Vote or Revoke My Proxy?” below.

What Does It Mean To Be A “Stockholder Of Record?”

You are a “stockholder of record” if your shares are registered directly in your name with our transfer agent, American Stock Transfer and Trust Company. As a stockholder of record, you have the right to grant your voting proxy directly to GI Dynamics or to vote in person at the Annual Meeting. If you received printed proxy materials, we have enclosed or sent a proxy card for you to use. You may also vote by Internet, as described below under the heading “How Do I Vote My Shares of GI Dynamics Common Stock?” Holders of CDIs are entitled to receive notice of and to attend the Annual Meeting and may direct CDN to vote at the Annual Meeting by following the instructions on the CDI Voting Instruction Form or by voting online at www.linkmarketservices.com.au.

What Does It Mean To Beneficially Own Shares In “Street Name?”

You are deemed to beneficially own your shares in “street name” if your shares are held in an account at a brokerage firm, bank, broker-dealer, trust, or other similar organization. If this is the case, the proxy materials were forwarded to you by that organization. As the beneficial owner, you have the right to direct your broker,

bank, trustee, or nominee how to vote your shares, and you are also invited to attend the Annual Meeting. If you hold your shares in street name and do not provide voting instructions to your broker, your shares will not be voted on any proposals on which your broker does not have discretionary authority to vote (a “brokernon-vote”).

Since a beneficial owner is not the stockholder of record, you may not vote your shares in person at the Annual Meeting unless you obtain a “legal proxy” from the broker, bank, trustee, or nominee that holds your shares giving you the right to vote the shares at the meeting. If you do not wish to vote in person or you will not be attending the Annual Meeting, you may vote by proxy. You may vote by proxy or by Internet, as described below under the heading “How Do I Vote My Shares of GI Dynamics Common Stock?”

How Do I Vote My Shares of GI Dynamics Common Stock?

Whether you plan to attend the Annual Meeting or not, we urge you to vote by proxy. If you vote by proxy, the individuals named on the proxy card, or your “proxies,” will vote your shares of common stock in the manner you indicate. You may specify whether your shares of common stock should be voted for, against, or abstain with respect to all of the Proposals to be voted on at the Annual Meeting. Voting by proxy will not affect your right to attend the Annual Meeting. If your shares of common stock are registered directly in your name through our stock transfer agent, American Stock Transfer and Trust Company, or you have stock certificates registered in your name, you may vote:

• By mail. Complete and mail the enclosed proxy card in the enclosed postage prepaid envelope. Your proxy will be voted in accordance with your instructions. If you sign the proxy card but do not specify how you want your shares of common stock voted, they will be voted as recommended by our Board of Directors. The proxy card must be received prior to the Annual Meeting.

• By Internet. Follow the instructions attached to the proxy card to vote by Internet.

• In person at the meeting. If you attend the Annual Meeting, you may deliver your completed proxy card in person or you may vote by completing a ballot, which will be available at the Annual Meeting.

Internet voting facilities for stockholders of record will be available24-hours a day and will close at 8:00 a.m. on Wednesday May 23, 2018 Australian Eastern Standard Time (which is 6:00 p.m. on Tuesday May 22, 2018 United States Eastern Daylight Time).

If your shares of common stock are held in “street name” (held in the name of a bank, broker, or other nominee), you must provide the bank, broker, or other holder of record with instructions on how to vote your shares of common stock and can do so as follows:

• By mail. Follow the instructions you receive from your broker or other nominee explaining how to vote your shares of common stock.

• By Internet or by telephone. Follow the instructions you receive from your broker or other nominee to vote by Internet or telephone.

• In person at the meeting. Contact the broker or other nominee who holds your shares of common stock to obtain a broker’s proxy card and bring it with you to the Annual Meeting. You will not be able to vote at the Annual Meeting unless you have a proxy card from your broker.

How Do I Vote If I Hold CDIs?

Each CDI holder is entitled to direct CDN to vote one vote for every fifty (50) CDIs held by such holder. Those persons holding CDIs are entitled to receive notice of and to attend the Annual Meeting and any adjournment or postponement thereof, and may direct CDN to vote their underlying shares of common stock at the Annual Meeting by voting online at www.linkmarketservices.com.au, or by returning the CDI Voting Instruction Form to Link Market Services Limited, the agent we designated for the collection and processing of voting instructions from our CDI holders, so that it is received by Link Market Services Limited no later than 8:00 a.m. on Tuesday May 22, 2018 Australian Eastern Standard Time (which is 6:00 p.m. on Monday May 21, 2018 United States Eastern Daylight Time) in accordance with the instructions on such form. Doing so permits CDI holders to instruct CDN to vote on their behalf in accordance with their written directions.

2

Alternatively, CDI holders have the following options in order to vote at the Annual Meeting:

• informing GI Dynamics that they wish to nominate themselves or another person to be appointed as CDN’s proxy for the purposes of attending and voting at the Annual Meeting; or

• converting their CDIs into a holding of shares of GI Dynamics common stock and voting these at the meeting (however, if thereafter the former CDI holder wishes to sell their investment on the ASX, it would be necessary to convert shares of common stock back into CDIs). This must be done prior to the Record Date for the Annual Meeting.

As holders of CDIs will not appear on GI Dynamics’ share register as the legal holders of the shares of common stock, they will not be entitled to vote at our stockholder meetings unless one of the above steps is undertaken.

How Does the Board of Directors Recommend That I Vote on the Proposals?

The board of directors (with Juliet Thompson abstaining from making a recommendation on Proposals 1 and 2 due to her personal interest in those proposals recommends that you vote as follows:

• “FOR” the election of the Class I director named in this proxy statement to hold office for a term of three years;

• “FOR” the approval of the grant of stock options to Juliet Thompson, a non-executive director of the Company;

• “FOR” the approval of the additional 10% placement capacity;

• “FOR” the approval of the issue of a US$1.75 million convertible note to Crystal Amber Fund Limited;

• “FOR” the approval of the issue of a warrant to Crystal Amber Fund Limited; and

• “FOR” the approval of the coming into effect of the conversion rights of Crystal Amber Fund Limited under the 2017 US$5.0 million convertible note that was issued to it by the Company in June 2017.

If any other matter is presented at the Annual Meeting, your proxy provides that your shares will be voted by the proxy holder listed in the proxy in accordance with his best judgment. At the time this proxy statement was first made available, we knew of no matters that needed to be acted on at the Annual Meeting, other than those discussed in this proxy statement

May I Change My Vote or Revoke My Proxy?

If you are a stockholder of record and give us your proxy, you may change your vote or revoke your proxy at any time before the Annual Meeting in any one of the following ways:

• if you received a proxy card, by signing a new proxy card with a date later than your previously delivered proxy and submitting it as instructed above;

• byre-voting by Internet as instructed above;

• by notifying our corporate secretary in writing at GI Dynamics, Inc., Post Office Box 51915 , Boston, MA 02205, U.S.A., Attention: Corporate Secretary before the Annual Meeting that you have revoked your proxy; or

• by attending the Annual Meeting in person, revoking your proxy and voting in person. Attending the Annual Meeting in person will not in and of itself revoke a previously submitted proxy. You must specifically request at the Annual Meeting that it be revoked.

Your most current vote, whether by Internet or proxy card, is the one that will be counted.

If you are a beneficial owner and hold shares of common stock through a broker, bank or other nominee, you may submit new voting instructions by contacting your broker, bank or other nominee. You may also change your vote or revoke your voting instructions in person at the Annual Meeting if you obtain a signed proxy from the record holder (broker, bank or other nominee) giving you the right to vote the shares of common stock.

3

If you are a holder of CDIs and you direct CDN to vote by completing the CDI Voting Instruction Form, you may revoke those directions by delivering to Link Market Services Limited a written notice of revocation bearing a later date than the CDI Voting Instruction Form previously sent which notice must be received by Link Market Services Limited no later than 8:00 a.m. on Tuesday May 22, 2018 Australian Eastern Standard Time (which is 6:00 p.m. on Monday May 21, 2018 United States Eastern Daylight Time).

Where Can I find the Voting Results of the Annual Meeting?

The preliminary voting results will be announced at the Annual Meeting. In accordance with the requirements of ASX Listing Rule 3.13.2, we will disclose to ASX the voting results of the Annual Meeting immediately after the meeting and will also report the results on a current report on Form8-K filed with the U.S. Securities and Exchange Commission.

How Do I Attend the Annual Meeting?

Admission to the Annual Meeting in person is limited to our stockholders or holders of CDIs, one member of their respective immediate families, or their named representatives. We reserve the right to limit the number of immediate family members or representatives who may attend the meeting. Stockholders of record, holders of CDIs of record, immediate family member guests, and representatives will be required to present government-issued photo identification (e.g., driver’s license or passport) to gain admission to the Annual Meeting.

To register to attend the Annual Meeting, please contact our Investor Relations as follows:

• bye-mail at investor@gidynamics.com;

• by phone at +1781-357-3250 in the U.S or at +61 2 9325 9046 in Australia;

Please be advised that no cameras, recording equipment, electronic devices, large bags, briefcases, or packages will be permitted in the Annual Meeting.

You need not attend the Annual Meeting in order to vote.

Will My Shares be Voted if I Do Not Vote?

If your shares are registered in your name or if you have stock certificates, they will not be counted if you do not vote as described above under “How Do I Vote My Shares of GI Dynamics Common Stock?” If your shares are held in street name and you do not provide voting instructions to the bank, broker or other nominee that holds your shares as described above, the bank, broker or other nominee that holds your shares does not have the authority to vote your unvoted shares without receiving instructions from you. Therefore, we encourage you to provide voting instructions to your bank, broker or other nominee. This ensures your shares will be voted at the Annual Meeting and in the manner you desire. A “brokernon-vote” will occur if your broker cannot vote

4

your shares on a particular matter because it has not received instructions from you and does not have discretionary voting authority on that matter or because your broker chooses not to vote on a matter for which it does have discretionary voting authority.

Our board is divided into three classes with staggered three-year terms. One class of directors is elected at each annual meeting of stockholders to serve for a three-year term, and those directors will hold office until their successors have been duly elected and qualified. Following the resignation of Jack Meyer, effective January 4, 2017, Michael A. Carusi, effective June 2, 2017, and Graham Bradley and Anne Keating, effective November 24, 2017, our board of directors currently consists of four (4) members, classified into three classes as follows: (1) Juliet Thompson constitutes a class with a term ending at this Annual Meeting (“Class I Director”); (2) Timothy J. Barberich constitutes a class with a term ending at the annual meeting of stockholders to be held in 2019 (“Class II Director”); and (3) Daniel J. Moore and Oern R. Stuge, M.D. constitute a class with a term ending at the annual meeting of stockholders to be held in 2020 (“Class III Directors”).

On August 22, 2017, our board of directors elected Juliet Thompson as a Class I Director of the Company for a term of three years to serve until the annual meeting of stockholders to be held in 2021, and until her respective successor has been duly elected and qualified.

Vote Required and Board of Directors Recommendation

Directors are elected by a plurality of the votes cast at the Annual Meeting, which means that the director nominees receiving the highest number of “FOR” votes will be elected as the Class I Director. Abstentions and brokernon-votes will have no direct effect on the outcome of this proposal.

Unless authority to vote for any of these nominees is withheld, the shares represented by the enclosed proxy will be votedFORthe election as Class I Director of Juliet Thompson. In the event that the nominee becomes unable or unwilling to serve, the shares represented by the enclosed proxy will be voted for the election of such other person as the board of directors may recommend in the nominee’s place. We have no reason to believe that the nominee will be unable or unwilling to serve as a director.

THE BOARD OF DIRECTORS (EXCLUDING JULIET THOMPSON WHO ABSTAINS FROM MAKING A RECOMMENDATION WITH RESPECT TO HER OWN ELECTION DUE TO HER PERSONAL INTEREST IN THE PROPOSAL) RECOMMENDS THE ELECTION OF JULIET THOMPSON AS A CLASS I DIRECTOR.

PROPOSAL 2: APPROVE THE GRANT OF STOCK OPTIONS TONON-EXECUTIVE DIRECTOR OF THE COMPANY

Background

As part of its overall compensation program, ournon-executive directors receive, subject to stockholder approval being obtained under the ASX Listing Rules, a significant portion of their annual compensation in the form of long-term incentive equity-based awards.

On August 22, 2017 (August 23, 2017, Australian Eastern Daylight Time), the board approved, subject to obtaining stockholder approval at this meeting, pursuant to the Company’s 2011 Employee, Director and Consultant Equity Incentive Plan (“2011 Plan”), the grant of 30,000 stock options to purchase 30,000 shares of our common stock (collectively, the “NED Options”) to Juliet Thompson, one of the Company’snon-executive directors (the“Non-Executive Director”), under our currentnon- employee director compensation program.

As of March 31, 2018, the market value of a share of common stock issuable upon exercise of a NED Option was US$1.04 based upon the closing price of our CDIs on the ASX on March 31, 2018. As of March 31, 2018, the Company had a total of 1,668,219 shares of common stock reserved for potential future issuance for employees, consultants and directors. Proposal 2 recommends the issuance of the NED Options to theNon- Executive Director, which, in aggregate, constitute approximately 1.8% of the total number of shares of common stock so reserved for potential future issuance.

Approvals

ASX Listing Rule 10.14 provides that a company must not permit a director to acquire securities under an employee incentive scheme without the prior approval of stockholders. Accordingly, stockholder approval is now being sought for the purposes of ASX Listing Rule 10.14 and for all other purposes for the grant of the NED Options to theNon-Executive Director as described below.

Principal Terms of Options

For the purposes of Listing Rules 10.14 and 10.15A the Company provides the following information.

If Proposal 2 is approved by stockholders, the corresponding NED Options will be issued to theNon-Executive Director as soon as practicable after the Annual Meeting and, in any case, no later than three years after the Annual Meeting.

The NED Options to be issued to theNon-Executive Director will be issued on the following terms and conditions:

(a) Grant Price: There is no consideration payable for the grant of the NED Options.

(b) Exercise Price:

(i) The exercise price of each of the NED Options is US$1.67, based upon the closing price of the Company’s CDIs on the ASX on August 22, 2017, the date of approval by the board of the grant of the NED Options to Juliet Thompson.

(ii) The NED Options are immediately exercisable upon issue and may be exercised at any time prior to their lapsing.

(c) Vesting Conditions:

(i) The NED Options shall vest over three years from the date of the options grant in (A) one installment of 33% of the shares on the first anniversary of the date of the options grant and (B) eight substantially equal installments vest on a quarterly basis thereafter.

(ii) Any shares which are received on exercise of NED Options exercised prior to vesting will be subject to a repurchase right by the Company until fully vested at the lesser of cost or fair market value.

8

(iii) All NED Options will vest in full upon a change in control event (as defined in theNon- Executive Director’s Option Agreement under the 2011 Plan).

(iv) There are no performance conditions or other requirements attaching to the NED Options other than the requirement that theNon-Executive Director continue to be a director of the Company at each relevant vesting date.

(d) Lapsing of NED Options: The NED Options will lapse in circumstances where:

(i) the NED Options have been exercised or otherwise settled;

(ii) theNon-Executive Director ceases to be a director of the Company on or prior to the date of vesting of the relevant NED Options; or

(iii) the NED Options have not been exercised by the tenth anniversary of the date of grant.

As further required by ASX Listing Rule 10.15A, the following additional information is provided in relation to Proposal 2:

• The maximum aggregate number of NED Options that may be granted by the Company under Proposal 2 is 30,000 NED Options to theNon-Executive Director.

• Upon exercise, each NED Option will entitle theNon-Executive Director to receive one share of common stock at the exercise price as set out above.

• No loans have been or will be made by the Company to theNon-Executive Director in connection with the acquisition of the NED Options or exercise of the NED Options.

• No individual referred to in ASX Listing Rule 10.14 has received securities under the 2011 Plan since stockholder approval was last obtained under ASX Listing Rule 10.14.

• Details of any securities issued under the 2011 Plan will be published in each annual report of the Company relating to a period in which securities have been issued, and that approval for the issue of the securities was obtained under ASX Listing Rule 10.14. Any additional persons who become entitled to participate in the 2011 Plan after the resolution was approved and who are not named in this proxy statement will not participate until approval is obtained under ASX Listing Rule 10.14.

Voting Exclusion Statement

The Company will disregard any votes cast on Proposal 2 by any Director of the Company or any associate of a Director of the Company. However, the Company need not disregard a vote if:

• it is cast by a person as a proxy for a person who is entitled to vote, in accordance with the direction on the proxy card; or,

• it is cast by the person chairing the meeting as a proxy for a person who is entitled to vote, in accordance with the direction on the proxy card to vote as the proxy decides.

Vote Required and Board of Directors Recommendation

Approval of Proposal 2 requires the affirmative vote of the holders of a majority of the shares of common stock present in person or represented by proxy at the Annual Meeting and voting on the proposal. Abstentions and brokernon-votes will have no direct effect on the outcome of this Proposal 2.

THE BOARD OF DIRECTORS (EXCLUDING JULIET THOMPSON, WHO DOES NOT MAKE A RECOMMENDATION WITH RESPECT TO PROPOSAL 2 DUE TO HER PERSONAL INTEREST IN THAT PROPOSAL) RECOMMENDS A VOTE “FOR” THE APPROVAL OF PROPOSAL 2.

PROPOSAL 3: APPROVE AN ADDITIONAL 10% PLACEMENT CAPACITY

Background

ASX Listing Rule 7.1 allows the Company to issue a maximum of 15% of its issued capital in any 12 month period without obtaining stockholder approval. In accordance with ASX Listing Rule 7.1A, eligible entities can issue a further 10% of their issued capital over a12-month period (“Placement Securities”) without obtaining stockholder approval for the individual issues provided that stockholder approval is obtained at the entity’s annual meeting (and the entity is an “eligible entity” at the time of the annual meeting). The Company is an “eligible entity” as at the date of this proxy statement.

Under ASX Listing Rule 7.1A, the Placement Securities must be in the same class as an existing quoted class of equity securities of the Company. As at the date of this proxy statement, the Company only has on issue one quoted class of equity securities, namely common stock, traded in the form of CDIs on the ASX.

The purpose of this Proposal 3 is to provide us with flexibility to meet future business and financial needs. We believe that it is advantageous for us to have the ability to act promptly with respect to potential opportunities and that approval of the issuance of the Placement Securities is desirable in order to have the securities available, as needed, for possible future financing transactions, strategic transactions, or other general corporate purposes that are determined by our board to be in the Company’s best interests.

Approval of this Proposal 3 would enable us to issue shares of common stock or CDIs without the expense and delay of holding a meeting of stockholders, except as may be required by applicable law or regulations. The cost, prior notice requirements, and delay involved in obtaining stockholder approval at the time a corporate action may become necessary could eliminate the opportunity to effect the action or could reduce the expected benefits.

Following the approval obtained at the Special Meeting of the Company on 28 February 2018, in which the Company obtained the approval of stockholders to refresh its placement capacity under ASX Listing Rule 7.1, if this Proposal is approved then, subject to the limitations described below with respect to the additional 10 percent placement capacity, we will generally be permitted to issue up to 25 percent of our issued and outstanding capital without any further stockholder approval in the next 12 months, unless such stockholder approval is required by applicable law, the rules of the ASX, or the rules of another stock exchange on which our securities may be listed at the time. As stated in our 2017 Annual Report, and other announcements and as evidenced in Proposals 4 and 5 to be considered at this Annual Meeting, the Company continues to consider its options for securing the required financing in order to continue its operations and this may require the Company to issue a material amount of new shares of common stock or CDIs. We believe that the adoption of this Proposal 3 will enable us to promptly and appropriately respond to business opportunities or raise additional equity capital. Our board of directors will determine the terms of any issuance of securities in the future.

Approvals

The Company is now seeking stockholder approval to have the ability to issue Placement Securities under ASX Listing Rule 7.1A. The exact number of Placement Securities that may be issued by the Company under ASX Listing Rule 7.1A will be determined in accordance with the formula prescribed in ASX Listing Rule 7.1A.2 (a copy of which is replicated below):

(A x D) - E

A =	The number of fully paid ordinary securities on issue 12 months before the date of issue or agreement:
	•  plus the number of fully paid ordinary securities issued in the 12 months under an exception in ASX Listing Rule 7.2;
	•  plus the number of partly paid ordinary securities that became fully paid in the 12 months;
	•  plus the number of fully paid ordinary securities issued in the 12 months with stockholder approval under ASX Listing Rules 7.1 and 7.4; and
	•  less the number of fully paid ordinary securities cancelled in the 12 months.
D =	10%

10

E = The number of equity securities issued or agreed to be issued under Listing Rule 7.1A.2 in the 12 months before the date of issue or agreement to issue that are not issued with stockholder approval under ASX Listing Rules 7.1 or 7.4.

If passed, Proposal 3 will allow the board of directors to issue up to an additional 10% of the Company’s issued capital during the12-month period following the date of the Annual Meeting without requiring further stockholder approval. This is in addition to the Company’s 15% annual placement capacity provided for in ASX Listing Rule 7.1 (for which stockholder approval was obtained at the February, 28 2018 Special Meeting to refresh the Company’s placement capacity under ASX Listing Rule 7.1).

As required by ASX Listing Rule 7.3A, the following additional information is provided in relation to Proposal 3:

(a) ASX Listing Rule 7.3A.1–The minimum price at which Placement Securities may be issued pursuant to this ASX Listing Rule 7.1A approval will be no less than 75% of the volume weighted average price of the Company’s CDIs calculated over the 15 trading days on which trades in that class were recorded immediately before:

(i) the date on which the price at which Placement Securities are to be issued is agreed; or

(ii) if Placement Securities are not issued within five trading days of the date in paragraph (i), the date on which Placement Securities are issued.

If Placement Securities are issued fornon-cash consideration the Company will provide to the market (in accordance with the ASX Listing Rules) a valuation of thenon-cash consideration that demonstrates that the issue price of such Placement Securities complies with ASX Listing Rule 7.3A.

(b) ASX Listing Rule 7.3A.2–If stockholders approve Proposal 3 and the Company issues Placement Securities under ASX Listing Rule 7.1A, the existing stockholders of the Company face the risk of economic and voting dilution as a result of the issue of Placement Securities, to the extent that such Placement Securities are issued, including the risk that:

(i) the market price for Placement Securities may be significantly lower on the issue date than on the date of the approval under ASX Listing Rule 7.1A; and

(ii) Placement Securities may be issued at a price that is at a discount to the market price for those securities on the issue date.

The following table describes the potential dilution of existing stockholders on the basis of three different issue prices and values for variable ‘A’ in the formula in ASX Listing Rule 7.1A.2. The prices and values set out in the table below are examples only and include scenarios prescribed by the ASX Listing Rules. Accordingly, they provide no indication of the actual market price of the Company’s CDIs or the price at which issues of Placement Securities under ASX Listing Rule 7.1A will be made (assuming Proposal 3 is approved by stockholders).

Variable A in Listing Rule 7.1A.2		Dilution
		Issue price of A$0.0125 (50% of the current market price of the Company’s CDIs)		Issue price of A$0.025 (the current price of the Company’s CDIs)		Issue price of A$0.050 (100% increase in the current price of the Company’s  CDIs)
616,655,049 CDIs (Current variable ‘A’)	10% Voting Dilution		61,665,505 CDIs		61,665,505 CDIs		61,665,505 CDIs
	Funds raised	AUD	770,819	AUD	1,541,638	AUD	3,083,275
924,982,574 CDIs (50% increase to current variable ‘A’)	10% Voting Dilution		92,498,257 CDIs		92,498,257 CDIs		92,498,257 CDIs
	Funds raised	AUD	1,156,228	AUD	2,312,456	AUD	4,624,913
1,233,310,098 CDIs (100% increase to current variable ‘A’)	10% Voting Dilution		123,331,009 CDIs		123,331,009 CDIs		123,331,009 CDIs
	Funds raised	AUD	1,541,638	AUD	3,083,275	AUD	6,166,550

Note: The above table has been prepared based on the following assumptions:

1. The Company issues (as CDIs) the maximum number of Placement Securities available under the 10% placement capacity prescribed by ASX Listing Rule 7.1A.

11

2. No options or convertible notes are exercised or converted (including those referred to in Proposals 4, 5 and 6 of this proxy statement) before the date of issue of Placement Securities under ASX Listing Rule 7.1A.

3. The 10% voting dilution reflects the aggregate percentage dilution against the issued share capital at the time of issue. This is why the voting dilution is shown in each example as 10%.

4. The table shows only the effect of issues of Placement Securities under ASX Listing Rule 7.1A, not under the Company’s 15% placement capacity under ASX Listing Rule 7.1.

5. The issue price of A$0.025 is the closing price of the Company’s CDIs on ASX on April 15, 2018.

6. All shares of common stock are held as CDIs

(c) ASX Listing Rule 7.3A.3 –The date Placement Securities must be issued by (assuming Proposal 3 is approved by stockholders) is the date that is 12 months after the date of the Company’s 2018 Annual Meeting (i.e., May 25, 2019, Australian Eastern Standard Time) unless the Company approves a transaction under ASX Listing Rule 11.1.2 (a significant change to the nature or scale of the Company’s activities) or ASX Listing Rule 11.2 (disposal of the Company’s main undertaking), in which case the ASX Listing Rule 7.1A approval under Proposal 3 will fall away on the date of stockholder approval for the relevant transaction.

(d) ASX Listing Rule 7.3A.4 –The Placement Securities will be issued for the purpose of funding the Company’s further development of the EndoBarrier^® for the treatment of patients who have uncontrolled type 2 diabetes and are obese and for raising working capital for the Company. The Company does not intend to issue any of the Placement Securities fornon-cash consideration; however, a valuation report would be provided in relation to any securities that were to be issued fornon-cash consideration.

(e) ASX Listing Rule 7.3A.5 – The Company’s allocation policy for issues of Placement Securities pursuant to approval under this Proposal 3 will depend on prevailing market conditions and the Company’s circumstances at the time of any proposed issue. The form and timing of any issue of Placement Securities under ASX Listing Rule 7.1A and the identity of the allottees of Placement Securities will be determined on a case by case basis having regard to any one or more of the following:

(i) the methods of raising funds available to the Company including, but not limited to, private placements, rights issues or other issues in which existing stockholders of the Company can participate;

(ii) the effect of the issue of Placement Securities on the control of the Company;

(iii) the financial situation of the Company; and

(iv) advice from any one or more of the Company’s professional advisers.

Allottees for the purposes of the issue of Placement Securities under ASX Listing Rule 7.1A have not been determined as at the date of this proxy statement but may include existing substantial stockholders and/or new stockholders who are not related parties or associates of a related party of the Company. In addition, if the Company is successful in acquiring new assets or investments it is possible that allottees for the purpose of the issue of Placement Securities under ASX Listing Rule 7.1A will be or include vendors of the new assets or investments.

As at the date of this proxy statement, the Company has not formed an intention as to the parties which it may approach to participate in an issue of Placement Securities under ASX Listing Rule 7.1A including whether such an issue would be made to existing stockholders or to new investors.

(f) ASX Listing Rule 7.3A.6 – The Company last obtained stockholders approval under ASX Listing Rule 7.1A on May 23, 2017 (Prior Approval).

(a) The Company has not issued any equity securities under ASX Listing Rule 7.1A approval between the date on which the Prior Approval was obtained and the date of the Annual Meeting.

(b) However for the purposes of ASX Listing Rule 7.3A.6(b) the Company has issued the following equity securities in the 12 months preceding the date of the Annual Meeting:

a. 41,500 stock options (equivalent to 2,075,000 CDIs if exercised) were issued to two advisors and two employees of the Company in accordance with the Company’s 2011 Equity Incentive Plan on 21 June 2017. The exercise price of all options granted were equal to the fair market value per share of common stock being A$2.46 or (A$0.065 per CDI).

12

b. 58,780,619 CDIs (representing 1,175,612 shares of common stock) were issued to select institutional investors via a private placement in two tranches as announced on 23 January 2018. Each CDI had an issue price of A$0.035 (being a premium to the CDI trading price at the time). The total cash consideration was approximately A$2.05 million. The proceeds raised from this issue were applied by the Company in full to fund the continued development of EndoBarier and for general working capital purposes.

In addition, Proposals 4, 5 and 6 set out in this proxy statement contain proposals to issue equity securities to the Company’s largest shareholder, Crystal Amber Fund Limited.

(g) ASX Listing Rule 7.1A.4 – In accordance with the requirements of ASX Listing Rule 7.1A.4, if the Company issues equity securities pursuant to ASX Listing Rule 7.1A (that is, being the additional placement capacity the subject of the approval sought under this Proposal 3), it will give to ASX:

(a) a list of the recipients of the securities and the number of equity securities issued to each (not for release to the market), in accordance with ASX Listing Rule 7.1A.4(a); and

(b) the information required by ASX Listing Rule 3.10.5A for release to the market, in accordance with ASX Listing Rule 7.1A.4(b).

Voting Exclusion Statement

The Company will disregard any votes cast in respect of Proposal 3 by a person who may participate in the proposed issue of any Placement Securities and a person who might obtain a benefit, except a benefit solely in the capacity of a holder of shares, if Proposal 3 is passed, and any associates of those persons. However, the Company need not disregard a vote cast on Proposal 3 if:

• it is cast by a person as proxy for a person who is entitled to vote, in accordance with the directions on the proxy card; or

• it is cast by the person chairing the meeting as proxy for a person who is entitled to vote, in accordance with a direction on the proxy card to vote as the proxy decides.

As at the date of this proxy statement, the Company has not entered into any definitive agreements to issue Placement Securities under ASX Listing Rule 7.1A and therefore it is not known who may participate in a potential issue of Placement Securities (if any) under ASX Listing Rule 7.1A. Accordingly, as at the date of this proxy statement, the Company is not aware of any person who would be excluded from voting on this Proposal 3.

Vote Required and Board of Directors Recommendation

Under ASX Listing Rule 7.1A, Proposal 3 is required to be passed as a “special resolution” for the purposes of the ASX Listing Rules, which means that it must be approved by at least 75% of the votes cast by stockholders entitled to vote on Proposal 3.

THE BOARD OF DIRECTORS HAS DETERMINED THAT PROPOSAL 3 IS IN THE BEST INTERESTS OF THE COMPANY AND UNANIMOUSLY RECOMMENDS A VOTE “FOR” PROPOSAL 3.

PROPOSAL 4 — APPROVAL OF THE ISSUE OF A CONVERTIBLE NOTE TO CRYSTAL AMBER FUND LIMITED

Background

To date, our product development efforts have been funded by a variety of capital received from various investors and the proceeds of our initial public offering and associated listing on ASX in 2011. Since our inception, we have received approximately US$234.4 million in net proceeds from sales of our equity and US$11.0 million from the issuance of promissory notes. As of March 31, 2018, we had approximately US$2.56 million in cash and investments available for operations. We have incurred substantial losses since our inception; as of March 31, 2018, we had an accumulated deficit of approximately US$261.0 million. We believe that our existing cash and investments at March 31, 2018 will be sufficient to meet anticipated cash requests until May 25, 2018 but not beyond.

We have been placing significant effort into raising more funds for the Company this year. In connection with these efforts, we have, as announced onMay 1, 2018, entered into a binding term sheet (“Term Sheet”) with the Company’s largest shareholder, Crystal Amber Fund Limited (“Crystal Amber”), pursuant to which the Company and Crystal Amber have agreed to enter into the following documents (“Transaction Documents”) immediately following this Annual Meeting:

• a Note and Warrant Purchase Agreement (“2018 Purchase Agreement”);

• a Senior Unsecured Convertible Promissory Note (“Note”); and

• a Warrant to Purchase Chess Depositary Interests (“Warrant”),

subject to the issue of the Note and the Warrant pursuant to the 2018 Purchase Agreement being approved by the Company’s stockholders at this Annual Meeting. If approval is not obtained, the Transaction Documents will not be entered into. A copy of the Term Sheet and each of the Transaction Documents is set out in Annexure A to this proxy statement (“Annexure A”).

Under the 2018 Purchase Agreement, the Company will agree to issue to Crystal Amber, on execution of the 2018 Purchase Agreement, the Note, which will have an issue price of US$1.75 million and a face value of US$1.75 million, to raise aggregate proceeds of US$1.75 million, before deducting fees and expenses, and which will be convertible, at Crystal Amber’s option, into CDIs or, if the Company is no longer listed on ASX at the time of conversion, common stock of the Company. As further consideration for Crystal Amber agreeing to subscribe for the Note, the Company will, on execution of the 2018 Purchase Agreement and the Note, also issue to Crystal Amber the Warrant, which will entitle Crystal Amber to subscribe for up to 97,222,200 CDIs or, if the Company is no longer listed on ASX at the time of such exercise, the corresponding number of shares of the Company’s common stock.

The initial conversion price under the Note will be US$0.018 for each CDI. This conversion price represents the volume weighted average closing price of the Company’s CDIs on the ASX for the five trading days immediately prior to the date of execution of the Term Sheet (“Initial Conversion Price”). The exercise price of each CDI under the Warrant is to be calculated on the same basis and therefore will also be US$0.018 (“Initial Exercise Price”).

Both the Initial Conversion Price and the Initial Exercise Price will be subject to adjustment as fully described in the Note and the Warrant respectively (copies of which are set out in Annexure A) and in the summary of their terms (which are set out in Annexure B to this proxy statement (“Annexure B”)).

By way of example, if the Note and Warrant were converted and exercised in full respectively on the date of this meeting:

• the Note would entitle Crystal Amber to be issued 97,222,200 CDIs (representing 1,944,444 shares of common stock) (being US$1.75 million divided by US$0.018, subject to rounding); and

• the Warrant would entitle Crystal Amber to subscribe for 97,222,200 CDIs (representing 1,944,444 shares of common stock) at a price per CDI equal to US$0.018,

14

which on issue would in aggregate represent 12.6 % of the Company’s then issued and outstanding capital on a fully diluted basis and would result in Crystal Amber’s percentage share ownership increasing on a fully diluted basis from 47.47% to 60.07% (based on its holding as of March 31, 2018).

The Note

A summary of the key terms of the Note is set out in Annexure B and a copy of each of the Transaction Documents (which sets out the full terms and conditions on which the Note and the Warrant will be issued to Crystal Amber) is set out in Annexure A.

The Note is a direct, unsubordinated and unsecured obligation of the Company and will be issued with a face value of US$1.75 million. The Note will not provide the holder with voting rights at stockholder meetings of the Company unless and until converted. Interest will accrue on the Note at the rate of 10% per annum (increased to 16% per annum if any payments are not paid by their due date), compounded annually.

On the earlier to occur of an Event of Default (as defined in the Transaction Documents) or 5 years after the date of issuance of the Note (being its maturity date), the Company is required to repay the Note if it has not otherwise been converted or repaid. The amount payable will be that amount which is equal to the aggregate of the outstanding amount of the Note’s face value plus all accrued but unpaid interest. The Company may not prepay the Note without Crystal Amber’s consent.

If a Change of Control of the Company (as defined in the Note) occurs prior to the Note’s maturity date, Crystal Amber may, at its option, require the Company to pay it an amount equal to 110% of the outstanding face value amount of the Note plus all unpaid interest to satisfy the Company’s obligations under the Note.

At any time following the date of issuance of the Note but prior to its maturity date, Crystal Amber will be entitled to give the Company an irrevocable notice electing to convert (all but not less than all of) the Note into CDIs, at the then effective conversion price. The conversion price will be the Initial Conversion Price, except that if, prior to the conversion, the Company makes an issuance of equity securities as part of an equity financing at a price lower than the Initial Conversion Price, the Initial Conversion Price will be adjusted to be the lowest such price (in US dollars) to ensure the economic value of the Note is not adversely affected. For example, if the Company issued CDIs at the equivalent of US$0.010 to an investor, Crystal Amber’s Initial Conversion Price would be reduced from US$0.018 to US$0.010. As a result, on conversion of the Note, Crystal Amber would be entitled to be issued 175,000,000 CDIs rather than 97,222,200 CDIs that would otherwise be issued to it using the US$0.018 conversion price.

Any securities issued upon conversion of the Note will be subject to anon-sale restriction for a period of 12 months after their issue, except as permitted by the Corporations Act 2001 (Cth).

The CDIs or shares of the Company’s common stock issued upon conversion of the Note will be fully paid and will in all respects rank pari passu with the fully paid CDIs or shares of the Company’s common stock on issue on the relevant conversion date.

Use of Proceeds

The Company intends to use the net proceeds raised from the Note to provide funding for the Company’s ongoing operating and working capital needs and ongoing development of EndoBarrier.

ASX Listing Rules

We are seeking approval of our stockholders for the purpose of approving the issuance of the Note and the subsequent issue of CDIs or common stock to Crystal Amber upon the conversion of the Note.

ASX Listing Rule 10.11 prohibits, subject to certain exceptions, a company from issuing or agreeing to issue equity securities to a related party. Crystal Amber is considered to be a related party because as of March 31, 2018 it owned 47.47% of the Company’s issued capital. Stockholder approval is now being sought under Proposal 4, for the purposes of ASX Listing Rule 10.11 and for all other purposes, to permit Crystal Amber to be issued the Note and any CDIs or shares of the Company’s common stock on subsequent conversion of the Note.

As stockholder approval is being sought under ASX Listing Rule 10.11, approval under ASX Listing Rule 7.1 is not required in accordance with ASX Listing Rule 7.2 (Exception 14). If Proposal 4 is approved, the

15

Note will be excluded from the calculation of the number of securities that can be issued by the Company in the 12 month period following the date of issue of the Note under ASX Listing Rule 7.1, therefore providing the Company with flexibility to issue securities in the next 12 months should the Board consider it is in the interests of the Company and its stockholders to do so.

In accordance with ASX Listing Rule 10.13, the following information is provided in relation to Proposal 4:

• the Note will be issued to Crystal Amber Fund Limited, a related party of the Company as detailed further above;

• there is only one Note and it has an issue price of US$1.75 million;

• the maximum number of CDIs that may be issued on conversion of the Note will be determined by dividing US$1.75 million (plus all accrued but unpaid interest at the conversion date) by the Initial Conversion Price, subject to any adjustment to that price as further described above and in the Note (a copy of which is set out in Annexure A);

• if approved, the Note will be issued within one month from the date of the Annual Meeting; and

• a summary of the terms and conditions of the Note to be issued is set out in Annexure B and the full set of terms and conditions on which the Note will be issued are set out in the 2018 Purchase Agreement and the Note copies of which are provided in Annexure A.

Consequences if this Proposal 4 is Approved but Proposal 5 is Not Approved

Proposals 4 and 5 are interconditional. Accordingly, if this Proposal 4 is approved but Proposal 5 is not approved, this Proposal 4 will be of no effect and the Note will not be issued to Crystal Amber. If this Proposal 4 is not approved, Proposal 5 will be withdrawn and not put to stockholders.

If stockholders do not approve Proposals 4 and 5, we will be unable to complete the financing transaction with Crystal Amber and unless we are able to obtain alternative financing, which may not be available to us on as favorable terms, or at all, we may be forced to consider a possible wind up or dissolution of our business.

PROPOSAL 5 — APPROVAL OF THE ISSUE OF A WARRANT TO CRYSTAL AMBER FUND LIMITED

Background

As described in Proposal 4 above, on May 1, 2018 the Company executed a binding Term Sheet with Crystal Amber Fund Limited (“Crystal Amber”) pursuant to which it was agreed, subject to obtaining stockholder approval, to issue a convertible note to Crystal Amber with an issue price of US$1.75 million and a face value of US$1.75 million, to raise aggregate proceeds of US$1.75 million, before deducting fees and expenses. In addition, as further consideration for Crystal Amber agreeing to subscribe for the Note (as defined in Proposal 4), and subject to obtaining stockholder approval for this Proposal 5, the Company has agreed, on execution of the Transaction Documents (as defined in Proposal 4), to issue to Crystal Amber a Warrant under the 2018 Purchase Agreement (as defined in Proposal 4) (“Warrant”) which will entitle Crystal Amber to subscribe for up to 97,222,200 CDIs or, if the Company is no longer listed on ASX at the time of such exercise, the corresponding number of shares of the Company’s common stock.

A copy of the Term Sheet and the Transaction Documents are set forth in Annexure A.

Terms of the Warrant

A summary of certain key terms of the Warrant is set out in Annexure B and a copy of the Warrant and the 2018 Purchase Agreement (which set out all of the terms on which the Warrant is to be issued to Crystal Amber is set out in Annexure A).

The Warrant will be exercisable by Crystal Amber at any time, in whole or in part and on multiple occasions on or after the date of its issuance until the date that is five years from the date of issuance (unless exercised in full earlier) at which point it lapses. The Warrant will not be quoted on ASX. Shares of the Company’s common stock or CDIs issued pursuant to an exercise of the Warrant will be fully paid and rank, from the date of exercise, equally with the existing shares of common stock and CDIs of the Company in all respects.

The initial exercise price of each CDI that may be purchased under the Warrant will be US$0.018, which is equal to the volume weighted average closing price of the Company’s CDIs on the ASX for the five trading days immediately prior to the date of execution of the Term Sheet (“Initial Exercise Price”). The Initial Exercise Price will be subject to adjustment as fully described below and in the Warrant (a copy of which is contained in Annexure A) and in the summary of its terms set out in Annexure B. If the Warrant was exercised in full on the date of this meeting, it would entitle Crystal Amber to be issued 97,222,200 CDIs, which on issue would represent 7.16% of the Company’s then issued capital on a fully diluted basis and would result in Crystal Amber’s percentage share ownership increasing on a fully diluted basis from 47.47% to 54.63% (based on its holding as of March 31, 2018). If, as stated in Proposal 4, the Note was also converted at the same time as the Warrant, Crystal Amber’s shareholding percentage would increase to 60.07% (based on its holding as of March 31, 2018).

If the Company issues equity securities at a price lower than the Initial Exercise Price prior to the exercise of the Warrant, the Initial Exercise Price will be adjusted to the lowest such price (in US dollars) to ensure the economic value of the Warrant is not adversely affected. For example, if the Company issued CDIs at the equivalent of US$0.010 to an investor, Crystal Amber’s Initial Exercise Price would be reduced from US$0.018 to US$0.010. As a result, Crystal Amber on exercise of the Warrant in full (assuming there had been no earlier exercise of the Warrant) would be entitled to purchase 97,222,200 CDIs at an exercise price per CDI equal to US$0.010 rather than US$0.018.

There are no participating rights or entitlements inherent in the Warrant and Crystal Amber will not be entitled to participate in new issues of capital that may be offered to stockholders (except where Crystal Amber has exercised the Warrant before the record date to participate in such new issue).

If there is a bonus issue to the holders of CDIs after the date of issue of the Warrant, the number of CDIs over which the Warrant would be exercisable would be increased by the number of CDIs which Crystal Amber would have received if it had exercised the Warrant before the record date for the bonus issue.

Additionally, if there is a pro rata issue (except a bonus issue) of securities to any holder of CDIs or shares of common stock after the date of issue of the Warrant, the then applicable exercise price for each CDI under the Warrant will be reduced in accordance with the formula set out in ASX Listing Rule 6.22.2.

17

Any securities issued upon exercise of the Warrant will be subject to anon-sale restriction for a period of 12 months after their issue, except as permitted by the Corporations Act 2001 (Cth).

Use of Proceeds

The Company intends to use the net proceeds raised from any exercise of the Warrant to provide funding for the Company’s ongoing operating and working capital needs and ongoing development of EndoBarrier.

ASX Listing Rules

We are seeking approval of our stockholders for the purpose of approving the issuance of the Warrant and the subsequent issue of CDIs or common stock to Crystal Amber upon the exercise of the Warrant.

ASX Listing Rule 10.11 prohibits, subject to certain exceptions, a company from issuing or agreeing to issue equity securities to a related party. Crystal Amber is considered to be a related party because as of March 31, 2018 it owned 47.47% of the Company’s issued capital. Therefore stockholder approval is now being sought under Proposal 5, for the purposes of ASX Listing Rule 10.11 and for all other purposes, to permit Crystal Amber to be issued the Warrant and any CDIs or shares of common stock on subsequent exercise of the Warrant.

As stockholder approval is being sought under ASX Listing Rule 10.11, approval under ASX Listing Rule 7.1 is not required in accordance with ASX Listing Rule 7.2 (Exception 14). If Proposal 5 is approved, the Warrant will be excluded from the calculation of the number of securities that can be issued by the Company in the 12 month period following the date of issue of the Warrant under ASX Listing Rule 7.1, therefore providing the Company with flexibility to issue securities in the next 12 months should the Board consider it is in the interests of the Company and its stockholders to do so.

In accordance with ASX Listing Rule 10.13, the following information is provided in relation to Proposal 5:

• the Warrant will be issued to Crystal Amber Fund Limited, a related party of the Company as detailed further above;

• the Warrant has a nil issue price. The exercise price (described above) will be payable in cash or may be settled by cashless exercise by the surrender of CDIs that may otherwise be issued on exercise under the Warrant;

• the maximum number of CDIs that may be issued on exercising the Warrant is 97,222,200;

• if approved, the Warrant will be issued within one month from the date of the Annual Meeting; and

• a summary of the terms and conditions of the Warrant to be issued is set out in Annexure B and the full set of terms and conditions on which the Warrant will be issued are set out in the 2018 Purchase Agreement and Warrant which are provided in Annexure A.

Consequences if this Proposal 5 is Approved but Proposal 4 is Not Approved

Proposals 4 and 5 are interconditional. As a result, if Proposal 4 is not approved at the Annual Meeting this Proposal 5 will be withdrawn and not put to stockholders for approval.

The implications of Proposals 4 and 5 not being approved, which are set out in the explanatory information for Proposal 4, should also be read in the context of this Proposal 5.

Voting Exclusion Statement

The Company will disregard any votes cast on Proposal 5 by Crystal Amber Fund Limited, or its nominee, or any associate of those persons. However, the Company need not disregard a vote if:

• it is cast by a person as a proxy for a person who is entitled to vote, in accordance with the direction on the proxy card; or

18

• it is cast by the person chairing the Annual Meeting as a proxy for a person who is entitled to vote, in accordance with a direction on the proxy card to vote as the proxy decides.

Vote Required

Approval of Proposal 5 requires the affirmative vote of the holders of a majority of the shares of common stock present in person or represented by proxy at the Annual Meeting and voting on the Proposal. Abstentions and brokernon-votes will have no direct effect on the outcome of this Proposal 5.

THE BOARD OF DIRECTORS HAS DETERMINED THAT PROPOSAL 5 IS IN THE BEST INTERESTS OF THE COMPANY AND UNANIMOUSLY RECOMMENDS THAT STOCKHOLDERS VOTE “FOR” PROPOSAL 5.

PROPOSAL 6 — APPROVAL OF THE 2017 CONVERTIBLE NOTE ISSUED TO CRYSTAL AMBER FUND LIMITED

Background

As previously announced, on June 15, 2017, the Company entered into a financing transaction with Crystal Amber Fund Limited (“Crystal Amber”) pursuant to which the Company issued a US$5.0 million secured convertible note with an issue price of US$5.0 million and a face value of US$5.0 million to Crystal Amber (“2017 Convertible Note”). A summary of certain key terms of the agreements that were entered into in respect of the 2017 Convertible Note, being a Note Purchase Agreement and a Security Agreement, each dated June 15, 2017 (together with the 2017 Convertible Note, “2017 Agreements”), is set out in Annexure D to this proxy statement (“Annexure D”).

Due to the timing of the finalization of the 2017 Convertible Note financing in 2017, the 2017 Convertible Note was issued without stockholder approval. As a consequence, while the 2017 Convertible Note contains conversion provisions, Crystal Amber has no right to exercise those rights unless and until such rights of exercise are approved by the stockholders of the Company. Accordingly, stockholder approval is now being sought to provide Crystal Amber with the right to convert its 2017 Convertible Note into CDIs of the Company should it wish to do so at any time during the remaining term of the 2017 Convertible Note in accordance with its terms.

Terms of the 2017 Convertible Note

A summary of certain of the key terms of the 2017 Convertible Note is set out in Annexure D and a copy of the 2017 Agreements (which set out the full terms and conditions of the 2017 Convertible Note) is set out in Annexure C to this proxy statement (“Annexure C”).

If this Proposal 6 is approved by stockholders, the terms contained in the 2017 Convertible Note which govern the right to convert the 2017 Convertible Note into CDIs of the Company will become operative. These terms provide that Crystal Amber will have, following obtaining stockholder approval under this Proposal 6, the following conversion rights:

a. the 2017 Convertible Note may be converted at any time by Crystal Amber prior to its maturity date (being December 31, 2018) by giving the Company an irrevocable notice electing to convert, at the then effective conversion price, all (but not less than all) of the outstanding amount of the face value of the 2017 Convertible Note plus all accrued but unpaid interest into CDIs (“Optional Conversion”). The conversion price per CDI will be the price determined by dividing the outstanding amount of the face value of the 2017 Convertible Note plus all accrued but unpaid interest by the five day volume weighted average closing price of the Company’s CDIs on the ASX (converted into US dollars) (“5 Day VWAP”) prior to the business day on which the notice to convert is received by the Company (“Optional Conversion Price”);

b. the outstanding amount of the face value of the 2017 Convertible Note plus all accrued but unpaid interest will automatically convert into CDIs on the occurrence of a Qualified Financing (as described in the 2017 Convertible Note, but essentially an equity raising of at least US$10 million). The conversion price will be the price per CDI (in US dollars) of the CDIs issued under the Qualified Financing (“QF Conversion Price”);

c. if a Change of Control of the Company (as described in the 2017 Convertible Note) occurs that is not the result of a Qualified Financing and the Company’s stockholders receivenon-cash consideration for their shares of common stock or CDIs under the relevant transaction, Crystal Amber will be able to convert the outstanding amount of the face value of the 2017 Convertible Note plus all accrued but unpaid interest into CDIs at the Optional Conversion Price (“Change of Control Conversion”); and

d. in the event the Company issues additional CDIs or common stock, or securities convertible into CDIs or common stock, in a subsequent equity raising (other than pursuant to a Qualified Financing) at a price per CDI (or the equivalent for shares of common stock) that is less than the then-effective Optional Conversion Price, Crystal Amber will have the period from the date of closing of the issuance of the additional CDIs or common stock until the date that is 30 days after the date the

20

Company has notified Crystal Amber of the key terms of that transaction in which to convert the outstanding amount of the face value of the 2017 Convertible Note plus all accrued but unpaid interest into CDIs, at an adjusted conversion price (in US dollars) reflecting, on a weighted average basis, the lower price per CDI paid in the other equity raising (“Non QF Conversion Price”). The number of CDIs that Crystal Amber may acquire upon conversion of the 2017 Convertible Note at this adjusted conversion price is limited to the number of CDIs that maintains Crystal Amber’s fully diluted ownership percentage of the Company at the same level as existed immediately preceding the applicable subsequent raising.

As a result, the actual conversion price payable for CDIs under the 2017 Convertible Note will be determined at the relevant time of conversion by the relevant circumstances at that time. The table below describes the potential number of CDIs that could be issued on an Optional Conversion or a Change of Control Conversion in various scenarios (with both conversions having a conversion price equal to the Optional Conversion Price). The prices and number of CDIs set out in the table are examples only. Importantly, they provide no indication of the actual market price of the Company’s CDIs or the actual conversion price of the CDIs or the actual number of CDIs to be issued on conversion (assuming that this Proposal 6 is approved).

Conversion Price	CDIs Issued1
Optional Conversion Price of US$0.018 as at 30 April 2018 (being the relevant 5 Day VWAP immediately prior to 30 April 2018) (April VWAP)	277,777,750 (representing 5,555,555 shares of common stock)
Optional Conversion Price of US$0.009 (assuming the relevant 5 Day VWAP at the date of conversion is 50% of the April VWAP, being US$0.009)	555,555,550 (representing 11,111,111 shares of common stock)
Optional Conversion Price of US$0.036 (assuming the relevant 5 Day VWAP at the date of conversion is double the April VWAP, being US$0.036)	138,888,850 (representing 2,777,777 shares of common stock)

¹  Assuming conversion of the full face value of the 2017 Convertible Note (US$5 million). This calculation does not take into account any additional CDIs that would be issued in consideration of the accrued but unpaid interest outstanding on the 2017 Convertible Note as at the conversion date.

The Non QF Conversion Price and the QF Conversion Price will depend on the circumstances of the Qualified Financing ornon-Qualified Financing as applicable. As a result, the relevant conversion price in those circumstances may vary considerably from the Optional Conversion Price. However, the Non QF Conversion Price will be lower than the Optional Conversion Price and the QF Conversion Price could be the same, higher or lower than the Optional Conversion Price depending on the issue price of the CDIs that are issued under the Qualified Financing.

The CDIs or shares of our common stock issued upon conversion of the 2017 Convertible Note will be fully paid and will in all respects rank pari passu with the fully paid CDIs or shares of our common stock on issue on the relevant conversion date.

Any CDIs or shares of common stock issued upon conversion the 2017 Convertible Note will be subject to anon-sale restriction for a period of 12 months after their issue, except as permitted by the Corporations Act 2001 (Cth).

Use of Proceeds

The Company has used the net proceeds raised from the 2017 Convertible Note offering to provide funding for the Company’s ongoing operating and working capital needs and ongoing development of EndoBarrier.

ASX Listing Rules

We are seeking approval of our stockholders for the purpose of allowing Crystal Amber to be able to exercise its conversion rights under the 2017 Convertible Note should it wish to do so during its remaining term, and to be issued CDIs upon any conversion of the 2017 Convertible Note in accordance with its terms.

21

ASX Listing Rule 10.11 prohibits, subject to certain exceptions, a company from issuing or agreeing to issue equity securities to a related party. Crystal Amber is considered to be a related party because as of March 31, 2018 it owned 47.47% of the Company’s issued capital and, if Crystal Amber has the right to convert the 2017 Convertible Note into CDIs, the Company will be viewed as having issued an equity security to Crystal Amber for the purposes of the ASX Listing Rules. Stockholder approval is now being sought under Proposal 6, for the purposes of ASX Listing Rule 10.11 and for all other purposes, to permit Crystal Amber to exercise the right of conversion under the 2017 Convertible Note and to be issued CDIs on such conversion.

As stockholder approval is being sought under ASX Listing Rule 10.11, approval under ASX Listing Rule 7.1 is not required in accordance with ASX Listing Rule 7.2 (Exception 14). If Proposal 6 is approved, the issue of any CDIs on conversion of the 2017 Convertible Note will be excluded from the calculation of the number of securities that can be issued by the Company in the 12 month period following such conversion under ASX Listing Rule 7.1, therefore providing the Company with flexibility to issue securities in the next 12 months should the Board consider it is in the interests of the Company and its stockholders to do so.

In accordance with ASX Listing Rule 10.13, the following information is provided in relation to Proposal 6:

• the 2017 Convertible Note was issued to Crystal Amber Fund Limited, a related party of the Company as detailed further above;

• there was only one 2017 Convertible Note and it had an issue price of US$5 million;

• the maximum number of CDIs that may be issued on conversion of the 2017 Convertible Note will be determined by dividing US$5 million (plus all accrued but unpaid interest) by the relevant conversion price at the time of conversion (which as noted above will be determined by the circumstances of such conversion), as further described above and in the 2017 Convertible Note (a copy of which is set out in Annexure C) and in Annexure D. Based on the Optional Conversion Price, the maximum number of CDIs that could be issued under the 2017 Convertible Note as at 30 April 2018 would be 289,916,613 CDIs (being the amount determined by dividing the face value of the 2017 Convertible Note (US$5 million) plus accrued but unpaid interest as at 30 April 2018 (US$218 thousand) by US$0.018, being the 5 Day VWAP up to 30 April 2018; and

• a summary of the terms and conditions of the 2017 Convertible Note is set out in Annexure D and the full set of terms and conditions on which the 2017 Convertible Note was issued is set out in the 2017 Agreements which are provided in Annexure C.

Consequences if this Proposal 6 is not approved

If this Proposal 6 is not approved, then 110% of the outstanding face value of the 2017 Convertible Note (being US$5.0 million) plus all accrued but unpaid interest under the 2017 Convertible Note must be repaid to Crystal Amber by the Company on or before the date that is 6 months after the date on which this Proposal 6 is not approved by stockholders.

Voting Exclusion Statement

The Company will disregard any votes cast on Proposal 6 by Crystal Amber Fund Limited, or its nominee, or any associate of those persons. However, the Company need not disregard a vote if:

• it is cast by a person as a proxy for a person who is entitled to vote, in accordance with the direction on the proxy card; or

• it is cast by the person chairing the Annual Meeting as a proxy for a person who is entitled to vote, in accordance with a direction on the proxy card to vote as the proxy decides.

Vote Required

Approval of Proposal 6 requires the affirmative vote of the holders of a majority of the shares of common stock present in person or represented by proxy at the Annual Meeting and voting on the Proposal. Abstentions and brokernon-votes will have no direct effect on the outcome of this Proposal 6.

Director Independence

Our board of directors currently consists of four (4) members: Timothy J. Barberich; Daniel J. Moore; Oern R. Stuge, M.D and Juliet Thompson. Our board of directors has determined that all directors are “independent.” We consider that a director is an “independent” director where that director is free from any business or other relationship that could materially interfere, or be perceived to interfere with, the independent exercise of the director’s judgment. We have assessed the independence of our directors regarding the requirements for independence that are set out in Principle 2 of the ASX Corporate Governance Principles. We have also assessed the independence of our directors with respect to the definition of independence prescribed by Nasdaq. There are no family relationships among our officers and directors, nor are there any arrangements or understandings between any of our directors or officers or any other person pursuant to which any officer or director was, or is, to be selected as an officer or director.

Committees of the Board of Directors and Meetings

The board of directors presently has the following three standing committees to facilitate and assist the board in fulfilling its responsibilities: (1) an audit committee, (2) a compensation committee and (3) a nominating and corporate governance committee. The board may also establish other committees from time to time to assist in the discharge of its responsibilities.

Meeting Attendance.During the fiscal year ended December 31, 2017 there were six (6) meetings of our board of directors, and the various committees of the board met a total of thirteen (13) times. No director other than Juliet Thompson who joined the board on August 2017, attended fewer than 75% of the total number of meetings of the board and of committees of the board on which he or she served during their Board term during fiscal 2017. We encourage all our directors to participate in each annual meeting of stockholders. Five of our directors attended our 2017 annual meeting of stockholders.

Audit Committee.Our audit committee met four (4) times during fiscal 2017. This committee currently has two (2) members: Juliet Thompson (chair) and Timothy J. Barberich. All members of the Audit Committee satisfy the current independence standards promulgated by the Securities and Exchange Commission (“SEC”); and by The Nasdaq Stock Market, as such standards apply specifically to members of audit committees. Our board of directors has determined that Juliet Thompson is an “audit committee financial expert,” as the SEC has defined that term. Our audit committee’s role and responsibilities are set forth in the audit committee’s written charter, a copy of which is publicly available on our website atwww.gidynamics.com. The audit committee, among other things, oversees our corporate accounting and financial reporting, including auditing of our financial statements, reviewing the performance of our internal audit function and the qualifications, independence, performance and terms of engagement of our external auditor.

Compensation Committee.Our compensation committee met one (1) time during fiscal 2017. This committee currently has two (2) members: Timothy J. Barberich (chair) and Dr. Oern Stuge. All members of the compensation committee qualify as independent under the current definition promulgated by The Nasdaq Stock Market. All members of the compensation committee qualify as independent under the current definition promulgated by the ASX. Our compensation committee’s role and responsibilities are set forth in the compensation committee’s written charter, a copy of which is publicly available on our website atwww.gidynamics.com. The compensation committee, among other things, establishes, amends, reviews and approves the compensation and benefit plans with respect to our senior management and employees including determining individual elements of total compensation of our chief executive officer and other members of senior

26

management. The compensation committee is also responsible for reviewing the performance of our executive officers with respect to these elements of compensation.

Nominating and Corporate Governance Committee.    Our nominating and corporate governance committee met twice (2) during fiscal 2017 and has two (2) members: Daniel Moore (chair) and Oern R. Stuge. All members of the nominating and corporate governance committee qualify as independent under the current definition promulgated by The Nasdaq Stock Market. All members of the nominating and corporate governance committee qualify as independent under the current definition promulgated by the ASX. The nominating and corporate governance committee’s role and responsibilities are set forth in the nominating and corporate governance committee’s written charter, a copy of which is publicly available on our website atwww.gidynamics.com. The nominating and corporate governance committee, among other things, recommends the director nominees for each annual meeting and ensures that the audit, compensation and nominating and corporate governance committees of the board have the benefit of qualified and experienced independent directors.

In addition, under our current Board Charter, the nominating and corporate governance committee will review annually the results of the evaluation of the board and its committees, and the needs of the board for various skills, experience, expected contributions and other characteristics in determining the director candidates to be nominated at the annual meeting. The nominating and corporate governance committee will evaluate candidates for directors proposed by directors, stockholders or management in light of the committee’s views of the current needs of the board for certain skills, experience or other characteristics, the candidate’s background, skills, experience, other characteristics and expected contributions and the qualification standards established from time to time by the nominating and corporate governance committee. If the nominating and corporate governance committee believes that the board requires additional candidates for nomination, the committee may engage, as appropriate, a third-party search firm to assist in identifying qualified candidates. All nominees for director positions will submit a completed form of directors’ and officers’ questionnaire as part of the nominating process. The process may also include interviews and additional background and reference checks for nonincumbent nominees, at the discretion of the nominating and corporate governance committee.

The nominating and corporate governance committee will review a reasonable number of candidates for director recommended by a single stockholder who has held over 5% of our common stock for over one year and who satisfies the notice, information and consent provisions set forth in our bylaws. Candidates so recommended will be reviewed using the same process and standards for reviewing board recommended candidates. If a stockholder wishes to nominate a candidate for director, it must follow the procedures described in our bylaws and in “Stockholder Proposals for 2019 Annual Meeting” at the end of this proxy statement.

1) The amounts in the “Stock Awards” column do not reflect compensation actually received by our executive officers. Rather, these amounts represent the aggregate grant date fair value of all service based RSUs and the target value of the performance based RSUs granted during each fiscal year computed in accordance with FASB ASC Topic 718,Compensation – Stock Compensation,excluding the impact of estimated forfeitures. The aggregate fair value of these stock awards is determined using the market value of our common stock which is derived from the market value of our CDIs on the ASX, converted to a USD equivalent and adjusting for the ratio of 1 share of common stock per 50 CDIs and using the exchange rate as published by the Reserve Bank of Australia in effect on the date of grant, multiplied by the aggregate number of restricted stock units granted. A discussion of the assumptions used in calculating the grant date fair value may be found in “Note 14 – Share Based Compensation” in the notes to our Financial Statements included in our Annual Report on Form10-K.

2) The amounts in the “Option Awards” column represent the aggregate grant date fair value for option awards awarded during fiscal years 2017 and 2016 computed in accordance with the provisions of FASB ASC Topic 718, excluding the impact of estimated forfeitures related to service-based vesting conditions. A discussion of the assumptions used in determining grant date fair value may be found in “Note 14 – Share Based Compensation” in the notes to our Financial Statements included in our Annual Report on Form10-K.

Potential Payments upon Termination or Change of Control

Upon termination of employment without cause or a resignation for good reason, our named executive officers and our current chief executive officer, Scott Schorer, are entitled to receive certain severance payments and other benefits. In determining whether to approve and in setting the terms of such severance arrangements, our compensation committee and our board recognize that executives, especially highly-ranked executives, often face challenges securing new employment following termination. We have agreed to provide severance benefits to our named executive officers and our current chief executive officer, as described below.

Scott Schorer. Severance amounts for termination without cause or a resignation for good reason for Mr. Schorer include: (A) an amount equal to six months of his base salary to be paid over asix-month period (unless such termination occurs (i) after December 31, 2017 or (ii) prior to January 1, 2018 and the Company has affirmatively decided to continue development of the EndoBarrier; in each such case Mr. Schorer will be entitled to receive 12 months of his base salary to be paid over a12-month period); apro-rata portion of Mr. Schorer’sat- target performance bonus as then in effect for the calendar year in which the termination occurs; and (C) COBRA premiums paid by the Company for Mr. Schorer and Mr. Schorer’s eligible dependents for up to six months after the termination date (unless such termination occurs (i) after December 31, 2017 or (ii) prior to January 1, 2018 and the Company has affirmatively decided to continue development of the EndoBarrier; in each such case Mr. Schorer will be entitled to such COBRA premium payments for up to 12 months after the termination date). Mr. Schorer’s offer letter also provides that 100% of any unvested stock options and performance stock units will immediately vest and become exercisable as of the consummation of a change in control in the Company.

Brian Callahan. Severance amounts for termination without cause or a resignation for good reason for Mr. Callahan include: (A) an amount equal to six months of his base salary to be paid over asix-month period (unless such termination occurs after December 31, 2017 or (ii) prior to January 1, 2018 and the Company has affirmatively decided to continue development of the EndoBarrier; in each such case Mr. Callahan will be entitled to receive 12 months of his base salary to be paid over a12-month period); (B) apro-rata portion of Mr. Callahan’sat-target performance bonus as then in effect for the calendar year in which the termination occurs; and (C) COBRA premiums paid by the Company for Mr. Callahan and Mr. Callahan’s eligible dependents for up to six months after the termination date (unless such termination occurs (i) after December 31, 2017 or (ii) prior to January 1, 2018 and the Company has affirmatively decided to continue development of the EndoBarrier; in each such case Mr. Callahan will be entitled to such COBRA premium payments for up to 12 months after the termination date). Mr. Callahan’s offer letter also provides that 100% of any unvested stock options and performance stock units will immediately vest and become exercisable as of the consummation of a change in control in the Company. On April 13, 2018, the Company terminated Mr. Callahan’s employment, with such termination to be effective May 15, 2018.

Karl Heinz-Blohm. Mr. Heinz-Blohm resigned his employment with the Company effective October 15, 2017.

We believe that our named executive officers’ and our current chief executive officer’s severance packages are in line with severance packages offered to executive officers of similar rank at companies of similar size to us in our industry.

(1) Juliet Thompson’s option award grant is subject to stockholder approval at the 2018 annual meeting of stockholders

There were no stock or option awards to directors in fiscal 2017 except as noted for Oern R. Stuge, M.D. and Juliet Thompson.

In August 2011, our board adopted anon-executive director compensation policy, which was amended in May 2014 and further amended in January 2017, pursuant to which thenon-executive directors will be compensated for their service on our board including as members of the various committees of our board. The number of directors on our board is determined from time to time by our board, up to a maximum of ten directors. The material terms of the policy are as follows:

• eachnon-executive director will receive an annual fee of $50,000 payable for the director’s service during the year;

• the chairman of our board will receive an additional annual fee of $25,000 payable for that director’s service during the year;

• eachnon-executive director who serves as either a member or chair of certain committees of our board will receive an additional annual fee for their work on such committee as either a member or chair as follows:

• audit committee: chair ($15,000) and member ($3,000);

• compensation committee: chair ($10,000) and member ($2,000); and

• nominating and corporate governance committee: chair ($5,000) and member ($1,000).

These fees are payable quarterly in arrears as of the last day of each fiscal quarter. Each director is also entitled to be reimbursed for reasonable travel and other expenses incurred in connection with attending meetings of our board and any committee on which he or she serves.

Each of ournon-executive directors received an initial grant ofnon-qualified options to purchase 13,000 shares of our common stock at the initial public offering price. These options were granted on August 1, 2011 to our then-servingnon-executive directors and vest as to 20% of the shares on the first anniversary of the grant date and to an additional 1.667% of the total shares on the same day of each month thereafter until August 1, 2016, subject to the director’s continued service on our board.

Eachnon-executive director whose service on our board commences at or following January 12, 2017 was granted anon-qualified stock option to purchase 30,000 shares of our common stock under our 2011 Stock

35

Plan on the date of his or her initial appointment or election to our board and furthermore, each continuing director thereafter shall be granted anon-qualified stock option to purchase 8,000 shares of our common stock under our 2011 Stock Plan. Each option granted upon initial appointment shall vest over three years from the date of the grant in (i) one installment of 33% of the shares on the first anniversary of the date of the grant and (ii) 24 substantially equal monthly installments thereafter, each subject to thenon-executive director’s continued service on our board. Each option granted to a continuing director shall grant in full on the first anniversary of the date of the grant.

In January 2014, at the recommendation of our compensation consultant, the board amended ournon- executive director compensation policy to reflect that beginning in 2014, eachnon-executive director shall be granted anon-qualified stock option to purchase 1,000 shares of our common stock and a restricted stock unit for 1,000 shares of our common stock under the 2011 Stock Plan each year. Each such award shall vest in full on the first anniversary of the grant date, each subject to thenon-executive director’s continued service on our board. On March 21, 2016, the board of directors waived the 2016 annual grant of stock options to purchase 1,000 shares of our common stock and a restricted stock unit for 1,000 shares of our common stock under our 2011 Stock Plan to each of ournon-executive directors under our currentnon-executive director compensation policy.

In January 2017, the board amended ournon-executive director compensation policy to reflect that beginning in 2017, eachnon-executive director shall be granted anon-qualified stock option to purchase 8,000 shares of our common stock under the 2011 Stock Plan each year. Each such award shall vest in full on the first anniversary of the grant date, each subject to thenon-executive director’s continued service on our board.

As a result of our listing on the ASX, all equity grants to directors are subject to stockholder approval under the ASX Listing Rules.

Unless otherwise specified by our board or the compensation committee at the time of grant, all options granted under this policy shall (i) have an exercise price equal to the fair market value of the Company’s common stock as determined pursuant to the 2011 Stock Plan on the date of grant and (ii) such options shall become exercisable in full immediately prior to a change of control of the Company. Ournon-executive directors in Australia will also be subject to asix-month restriction on selling any of our common stock or CDIs following the exercise of their options.

EQUITY COMPENSATION PLAN INFORMATION

The table below sets forth information with regard to shares authorized for issuance under our equity compensation plans as of December 31, 2017. As of December 31, 2017, we had two active equity compensation plans, each of which was approved by our stockholders:

• Our 2003 Omnibus Stock Plan; and

• Our 2011 Employee, Director and Consultant Equity Incentive Plan.

Plan Category	Number of shares to be issued upon exercise of outstanding options or  vesting of restricted stock units		Weighted-average exercise price of outstanding options		Number of shares remaining available for future issuance under  equity compensation plans1

Equity compensation plans not approved by security holders		–				–
Total		1,384,880		9.77		1,181,920

1)    Our 2011 Employee, Director and Consultant Equity Incentive Plan allows for an annual increase in the number of shares available for issue commencing on the first day of each fiscal year during the period beginning in fiscal year 2012 and ending in fiscal year 2020. The annual increase in the number of shares shall be equal to the lowest of: (i) 500,000 shares; (ii) 4% of the number of common shares outstanding as of such date; and (iii) an amount determined by our board of directors or our compensation committee.

SECURITY OWNERSHIP OF CERTAIN BENEFICIAL OWNERS AND MANAGEMENT

The following table sets forth, as of March 31, 2018, information regarding beneficial ownership of our common stock, and common stock held as CDIs, by the following:

• each person, or group of affiliated persons, who is known by us to beneficially own 5% or more of any class of our voting securities;

• each of our directors;

• each of our named executive officers; and

• all current directors and executive officers as a group.

Beneficial ownership is determined according to the rules of the SEC. Beneficial ownership generally includes voting or investment power of a security and includes shares underlying options that are currently exercisable or exercisable within 60 days of March 31, 2018. This table is based on information supplied by officers, directors and principal stockholders. Except as otherwise indicated, we believe that the beneficial owners of the CDIs and common stock listed below, based on the information each of them has given to us, have sole investment and voting power with respect to their shares, except where community property laws may apply.

Percentage of ownership is based on 12,333,101 shares of outstanding common stock, or common stock equivalent CDIs, outstanding on March 31, 2018. Unless otherwise indicated, we deem shares subject to options that are exercisable within 60 days of March 31, 2018, to be outstanding and beneficially owned by the person holding the options for the purpose of computing percentage ownership of that person, but we do not treat them as outstanding for the purpose of computing the ownership percentage of any other person.

Following our reverse stock split effected on April 9, 2015, because CDIs representone-fiftieth of a share of our common stock, converting the number of CDIs owned by the person holding them into the equivalent number of shares of common stock may result in fractional shares of common stock. In the following table, the number of shares of common stock owned by each beneficial owner is rounded down to the nearest whole share of common stock.

Unless otherwise indicated in the table, the address of each of the individuals named below is: c/o GI Dynamics, Inc., PO Box 51915, Boston, MA 02205, U.S.A.

The audit committee is responsible for overseeing our overall financial reporting process, and for the appointment, compensation, retention, and oversight of the work of Moody, Famiglietti & Andronico, LLP. In fulfilling its responsibilities for the financial statements for fiscal year 2017, the audit committee took the following actions:

The Company is duly qualified to transact business and is in good standing in the Commonwealth of Massachusetts and in each jurisdiction in which its ownership of property or the nature of the business conducted by it makes such qualification necessary.

3.2 Corporate Power. The Company has all requisite corporate power to execute and deliver this Agreement, the Note and the Warrant in favor of the Purchaser and any other document provided for herein or by any of the foregoing (collectively, as the same may from to time be amended, modified, supplemented or restated, the “Loan Documents”) and to carry out and perform its obligations under the terms of the Loan Documents and to issue CDIs in accordance with the terms thereof.

(a) Authorization. The execution and delivery of each of the Loan Documents by the Company and the consummation by the Company of the transactions contemplated hereby and thereby, including, without limitation, the issuance of the Note, the issuance of the Warrant, the reservation of the Common Stock underlying the CDIs issuable upon conversion of the Note (the “Conversion CDIs”), the reservation of the Common Stock underlying the CDIs issuable upon exercise of the Warrant (the “Warrant CDIs” and, together with the Note, the Warrant, the Conversion CDIs and the Common Stock, “Securities”) and the issuance of the Conversion CDIs and the Warrant CDIs, was duly authorized by the Company’s board of directors. Other than those consents and authorizations

obtained by the Company prior to the date hereof that are in full force and effect on the Closing Date, no further consent or authorization is required by the Company, its board of directors or its stockholders. Each of the Loan Documents has been duly executed and delivered by the Company, and constitutes the legal, valid and binding obligations of the Company enforceable in accordance with its terms, subject to laws of general application relating to equitable principles, bankruptcy, insolvency and the relief of debtors. Upon conversion of the Note into Conversion CDIs in accordance with the provisions of this Agreement and the Note, the Conversion CDIs will be validly issued, fully paid and nonassessable and free of any liens or encumbrances (other than as set out in Section 2(e) of the Note). Upon the exercise of the Warrant in accordance with the provisions of this Agreement and the Warrant, the Warrant CDIs will be validly issued, fully paid and nonassessable and free of any liens or encumbrances (other than as set out in Section 5(b) of the Warrant). The issuance of the Note (and the Conversion CDIs) and the Warrant (and the Warrant CDIs) pursuant to the provisions of this Agreement will not give rise to any preemptive rights or rights of first refusal granted by the Company, and the Note (and the Conversion CDIs) and the Warrant (and the Warrant CDIs) will be issued in compliance with all applicable federal and state securities laws, and will be free of any liens or encumbrances;provided, however, that the Note and the Warrant (and the underlying securities) may be subject to restrictions on transfer as set out in the Loan Documents or under state and/or federal securities laws as set forth herein or as otherwise required by such laws at the time the transfer is proposed. The issuance and sale of the Note (and the Conversion CDIs) and the Warrant (and the Warrant CDIs) do not and will not cause any dilution adjustment in any existing securities of the Company, and the Purchaser hereby waives any dilution adjustment that might otherwise result from the issuance and sale of the Note (and the Conversion CDIs) or the Warrant (and the Warrant CDIs) pursuant to the terms of any existing security held by the Purchaser.

3.3 Governmental Consents. All consents, approvals, orders, or authorizations of, or registrations, qualifications, designations, declarations, or filings with, any governmental authority, required on the part of the Company in connection with the valid execution and delivery of the Loan Documents, the offer, sale or issuance of the Note, the Conversion CDIs, the Warrant and the Warrant CDIs, or the consummation of any other transaction contemplated hereby shall have been obtained and will be effective at the Closing, except for any notices required or permitted to be filed with certain foreign, state and/or federal securities commissions or stock exchanges, which notices will be filed on a timely basis.

3.4 No Conflicts. The execution, delivery and performance of the Loan Documents by the Company and the consummation by the Company of the transactions contemplated hereby and thereby (including, without limitation, the issuance of the Note and the Warrant and the reservation for issuance and issuance of the Conversion CDIs and the Warrant CDIs) will not (i) result in a violation of the certificate of incorporation or by-laws of the Company or (ii) conflict with, or constitute a default (or an event which with notice or lapse of time or both would become a default) under, or give to others any rights of termination, amendment, acceleration or cancellation of, any material agreement, indenture or instrument to which the Company is a party or by which the Company is bound, or (iii) result in a violation of any law, rule, regulation, order, judgment or decree including federal and state securities laws and regulations applicable to the Company or by which any property or asset of the Company is bound or affected. For the avoidance of doubt, the Purchaser agrees that the execution, delivery and performance of the Loan Documents by the Company and the consummation by the Company of the transactions contemplated hereby and thereby shall not conflict with or constitute a default under the Note Purchase Agreement, dated as of June 15, 2017, between the Company and the Purchaser, including, without limitation, the restriction on additional indebtedness set forth in Section 3.14 thereof.

3.5 Offering. Assuming the accuracy of the representations and warranties of the Purchaser contained inSection 4 hereof, the offer, issue, and sale of the Note and the Warrant is and will be exempt from the registration and prospectus delivery requirements of the Securities Act of 1933, as amended (the “Act”), and has been registered or qualified (or is exempt from registration and qualification) under the registration, permit, or qualification requirements of all applicable state securities laws.

During the two (2) years prior to the date hereof, the Company has filed all reports, schedules, forms, statements and other documents required to be filed by it with the SEC pursuant to the reporting requirements of 1934 Act (all of the foregoing filed prior to the date hereof or prior to the date of the Closing, and all exhibits included therein and financial statements, notes and schedules thereto and documents incorporated by reference therein being hereinafter

referred to as the “SEC Documents”).

As of their respective filing dates, or, if amended or superseded by a subsequent filing, as of the date of the last such amendment or superseding filing, the financial statements of the Company included in the SEC Documents complied as to form in all material respects with applicable accounting requirements and the published rules and regulations of the SEC with respect thereto. Such financial statements have been prepared in accordance with generally accepted accounting principles, consistently applied, during the periods involved (except (i) as may be otherwise indicated in such financial statements or the notes thereto, or (ii) in the case of unaudited interim statements, to the extent they may exclude footnotes or may be condensed or summary statements) and fairly present in all material respects the financial position of the Company as of the dates thereof and the results of its operations and cash flows for the periods then ended (subject, in the case of unaudited statements, to normal year-end audit adjustments).

To the knowledge of the Company, the Company is not in violation of any term of, or in default under, its Certificate of Incorporation, as amended and as in effect on the date hereof, or any certificate of designation of an outstanding series of stock of the Company or Bylaws, as amended and as in effect on the date hereof. The Company is not in violation of any judgment, decree or order or any statute, ordinance, rule or regulation applicable to the Company, and the Company does not and will not conduct its business in violation of any of the foregoing, except for possible violations which could not, individually or in the aggregate, reasonably be expected to have a material adverse effect on the Company. Without limiting the generality of the foregoing, the Company is not in violation of any of the rules, regulations or requirements of the ASX (defined below) and, assuming the Note and Warrant are issued, has no knowledge of any facts or circumstances that would reasonably lead to delisting or suspension of its securities by the ASX in the foreseeable future. Except as set forth in its SEC Filings, the Company possesses all certificates, authorizations and permits issued by the appropriate federal, state or foreign regulatory authorities necessary to conduct its business, and the Company has not received any notice of proceedings relating to the revocation or modification of any such certificate, authorization or permit.

3.10 Securities Laws. The Company shall timely make all filings and reports relating to the issuance of the Securities required under applicable securities laws, including filing any notice of sale of securities required by applicable law or regulation and complying with any applicable “blue sky” laws of the states of the United States.

transfer by the Purchaser to (i) any shareholder, partner, retired partner, member or former member of the Purchaser for no additional consideration or (ii) any affiliate, including affiliated funds, for no additional consideration, in each case if all transferees agree in writing to be subject to the terms hereof to the same extent as if they were the Purchaser hereunder.

(d)Notwithstanding the provisions of paragraphs (a) and (b) above, the Company acknowledges and agrees that the Securities may be pledged by the Purchaser, and its successors and assigns, in connection with a bona fide margin agreement or other loan or financing arrangement that is secured by the Securities, provided that any pledge of those Securities does not constitute an offer of those Securities for sale within 12 months after their issue such that it would require disclosure under section 707(3) of theCorporations Act 2001(Cth). The pledge of Securities shall not be deemed to be a transfer, sale or assignment of the Securities hereunder, and no Person effecting a pledge of Securities shall be required to provide the Company with any notice thereof or otherwise make any delivery to the Company pursuant to this Agreement or any other Loan Document. The Company hereby agrees to execute and deliver such documentation as a pledgee of the Securities may reasonably request, at the Purchaser’s expense, in connection with a pledge of the Securities to such pledgee by the Purchaser and any successor or assignee.

4.11 Foreign Ownership Restrictions. The Purchaser acknowledges and agrees that in order to ensure that US persons do not purchase any CDIs that may be issued to it, a number of procedures governing the trading and clearing of CDIs, while the Company is listed on the Australian Securities Exchange (the “ASX”), will be implemented, including the application to any CDIs issued to it of the status of Foreign Ownership Restrictions securities under the ASX Settlement Operating Rules and the addition of the notation “FORUS” to the CDI description on ASX trading screens and elsewhere, which will inform the market of the prohibition of US persons acquiring CDIs.

(v) deliver to the Holder a check payable to Holder for any cash amounts payable as a result of any fractional shares.

If, at the time of conversion, CDIs are no longer quoted on ASX, then on conversion of the Note the Payor must issue directly to the Holder the number of shares of Common Stock over which the Note is convertible into and must procure that those shares be listed for trading on any securities exchange on which the Payor’s Common Stock is tradeable and deliver to the Holder a check payable to Holder for any cash amounts payable as a result of any fractional shares.

(d)Holder Representations and Warranties; Transfer and Assignment. The representations and warranties and rights and obligations of transfer and assignment of Holder that are set forth inSection 4 of the Purchase Agreement with respect to the shares of Common Stock or CDIs issuable to Holder are hereby made a part of this Note and incorporated herein by this reference.

6. FUNDAMENTAL TRANSACTIONS; CORPORATE EVENTS.

(a)Fundamental Transactions. If, at any time while this Note is outstanding, (i) the Payor effects any merger or consolidation of the Payor with or into another person pursuant to which the Common Stock is effectively converted and exchanged, (ii) the Payor effects any sale of all or substantially all of its assets in one or a series of related transactions pursuant to which the Common Stock is effectively converted and exchanged, (iii) any tender offer or exchange offer (whether by the Payor or another person) is completed pursuant to which at least a majority of the outstanding Common Stock is tendered and exchanged for other securities, cash or property or (iv) the Payor effects any reclassification of the Common Stock or any compulsory share exchange pursuant to which the Common Stock is effectively converted into or exchanged for other securities, cash or property (other than as a result of a subdivision or combination of shares of Common Stock) (in any such case, a “Fundamental Transaction”), then prior to any subsequent conversion of this Note, and subject to the provisions ofSection 2(b) hereof, the Holder shall be entitled to require the surviving entity to issue to the Holder an instrument identical to this Note (with an appropriate adjustment to the conversion price(s)) such that the Holder may receive stock (or a beneficial interest in stock) of the surviving company’s stock. Subject to the provisions ofSection 2(b) hereof, the terms of any agreement pursuant to which a Fundamental Transaction is effected shall include terms requiring any such successor or surviving entity to comply with the provisions of this paragraph (a) and insuring that this Note (or any such replacement security) will be similarly adjusted upon any subsequent transaction analogous to a Fundamental Transaction.

(b)Notice of Corporate Events. If the Payor (i) declares a dividend or any other distribution of cash, securities or other property in respect of its Common Stock, including without limitation any granting of rights or warrants to subscribe for or purchase any shares of the Payor or any subsidiary, (ii) authorizes and publicly approves, or enters into any agreement contemplating or solicits stockholder approval for any Fundamental Transaction or (iii) publicly authorizes the voluntary dissolution, liquidation or winding up of the affairs of the Payor, then the Payor shall deliver to the Holder a notice describing the material terms and conditions of such transaction, at least ten (10) business days prior to the applicable record or effective date on which a person would need to hold Common Stock or CDIs in order to participate in or vote with respect to such transaction, and the Payor will take all steps reasonably necessary in order to insure that the Holder is given the practical opportunity to convert this Note prior to such time so as to participate in or vote with respect to such transaction; provided, however, that the failure to deliver such notice or any defect therein shall not affect the validity of the corporate action required to be described in such notice.

(c)Subsequent Equity Sales. Notwithstanding any provision of this Note to the contrary, in the event that the Payor issues any CDIs or Common Stock or any security that is exchangeable or convertible into CDIs or Common Stock (“Additional Securities”) after the date hereof at a price per CDI (or the equivalent for shares of Common Stock) that is less than the Conversion Price (or the equivalent for shares of Common Stock) in an equity financing, then the Conversion Price shall be reduced to the lowest price per CDI (or the equivalent for shares of Common Stock) at which any Additional Security was issued or sold or deemed to be issued or sold. The Payor agrees that it will provide a notice to the Holder describing the material terms and conditions of any

3

issuance of Additional Securities promptly after the issuance thereof. For the avoidance of doubt, the price per CDI (or the equivalent for shares of Common Stock) at which any Additional Securities are issued by the Payor to the Holder after the date hereof, including, without limitation, upon conversion into CDIs or Common Stock of the Senior Secured Convertible Promissory Note, dated June 15, 2017, issued to the Holder by the Payor, will have no effect on the Conversion Price.

The right to plead any and all statutes of limitations as a defense to any demands hereunder is hereby waived to the full extent permitted by law. No delay by Holder shall constitute a waiver, election or acquiescence by it.

8. CUMULATIVE REMEDIES. Holder’s rights and remedies under this Note and the Purchase Agreement shall be cumulative. No exercise by Holder of one right or remedy shall be deemed an election, and no waiver by Holder of any Event of Default shall be deemed a continuing waiver of such Event of Default or the waiver of any other Event of Default.

WARRANT TO PURCHASE CHESS DEPOSITARY INTERESTS

Issue Date: [                ], 2018

This Warrant to Purchase CHESS Depositary Interests (the “Warrant”) certifies that, for good and valuable consideration,CRYSTAL AMBER FUND LIMITED(along with its permitted assignees, the “Holder”) is entitled to, andGI DYNAMICS, INC., a Delaware corporation (the “Company”), hereby grants the Holder the right to, purchase, as of the date of issuance set forth above (the “Issue Date”), up to such number of fully paid andnon-assessable CHESS Depositary Interests (with each CDI representing 1/50th of a share of the Company’s common stock, par value $0.01 per share (the “Common Stock”)) (the “CDIs”) as determined pursuant toSection 1(a) below, at a price per CDI equal to the Exercise Price (as defined below), subject to the provisions and upon the terms and conditions set forth in this Warrant. This Warrant is issued pursuant to the Note and Warrant Purchase Agreement (the “Purchase Agreement”) dated as of [                ], 2018 by and between the Company and the Holder.

1. Number of CDIs; Exercise Price

(a)Number of CDIs. Upon the making of loan to the Company as evidenced by the Note (as defined in the Purchase Agreement), this Warrant automatically shall become exercisable for 97,222,200 CDIs (representing 1,944,444 shares of Common Stock). All CDIs for which this Warrant becomes exercisable from time to time pursuant to this Paragraph 1(a), and as may be adjusted from time to time in accordance with the provisions of this Warrant, are referred to herein cumulatively and collectively as the “Warrant CDIs.”

(b)Exercise Price. With respect to each Warrant CDI for which this Warrant becomes exercisable pursuant to Paragraph 1(a) above, the purchase price therefor (the “Exercise Price”) shall be US$0.018.

2. Exercise; Payment.

(a)Method of Exercise. This Warrant may be exercised by the Holder at any time during the term (as set forth inSection 8) and in compliance with the provisions of this Warrant for all or any part of the Warrant CDIs, by the surrender of this Warrant together with the duly executed notice of exercise form attached hereto asExhibit A (the “Notice of Exercise”) at the principal office address of the Company. If this Warrant shall have been exercised in part, the Company shall, at the time of delivery of the Holding Statement or the book entry notice pursuant toSection 2(e), deliver to the Holder a new Warrant evidencing the rights of the Holder to purchase the then unpurchased Warrant CDIs, which new Warrant shall in all other respects be identical to this Warrant, or at the request of the Holder, appropriate notation may be made on this Warrant and the same returned to the Holder.

(b)Cash Exercise. Upon exercise of this Warrant, the Holder shall pay the Company an amount (“Exercise Payment”) equal to the product of the Exercise Pricemultiplied by the total number of Warrant CDIs purchased pursuant to such exercise of this Warrant, by wire transfer of immediately available funds or check payable to the order of the Company. In the manner set out in Paragraph (e) below, the Holder shall be deemed to have become the holder of record of, and shall be treated for all purposes as the record holder of, the Warrant CDIs represented by such exercise (and such Warrant CDIs shall be deemed to have been issued) immediately prior to the close of business on the date upon which the Exercise Payment is paid to the Company.

(c)Net Exercise. The Exercise Payment also may be paid at the Holder’s election by surrender of all or a portion of the Warrant for the Warrant CDIs to be exercised under this Warrant (“Net Exercise”). If the

Holder elects the Net Exercise method, the Company will issue Warrant CDIs in accordance with the following formula:

X = Y(A-B)

        A

Where:

X =	the number of Warrant CDIs to be issued upon the Net Exercise of
	the Warrant
Y =	the number of Warrant CDIs to be surrendered
A =	the fair market value of one (1) CDI on the date of exercise of this
	Warrant
B =	the Exercise Price

For purposes of the above calculation, fair market value of CDIs shall mean the following (“Fair Market Value”):

(i) if CDIs are then quoted on the Australian Securities Exchange (“ASX”), then the Fair Market Value per share of one (1) CDI shall be equal to the volume weighted average closing price of the Company’s CDIs on the ASX for the five (5) trading days ending immediately prior to the business day on which the Company receives the Holder’s written Notice of Exercise (regardless if received during the trading hours or after);

(ii) if CDIs are not then quoted on the ASX, then if the Company’s Common Stock is traded on another national securities exchange, the Fair Market Value of the CDIs shall be equal to the result obtained bydividing (A) the volume weighted average closing price of the Company’s Common Stock on such securities exchange for the five (5) trading days ending immediately prior to the business day on which the Company receives the Holder’s written Notice of Exercise (regardless if received during the trading hours or after), by (B) the number of CDIs (or fraction thereof) which equal an interest in exactly one share of Common Stock on such dates;

(iii) if CDIs are not then quoted on the ASX and the Common Stock is not then traded on another securities exchange, then if the Common Stock is tradedover-the-counter, the Fair Market Value of the CDIs shall be equal to the result obtained bydividing (A) the volume weighted average closing price of the Company’s Common Stock quoted on the principal market on which or through which the Common Stock is traded over the five (5) consecutive trading days ending immediately prior to the business day on which the Company receives the Holder’s written Notice of Exercise (regardless if received during the trading hours or after), by (B) the number of CDIs (or fraction thereof) which equal an interest in exactly one share of Common Stock on such dates; or

(iv) if CDIs are not then quoted on the ASX and the Common Stock is not then listed on any securities exchange or traded in theover-the-counter market, the Fair Market Value of the CDIs shall be as determined by its Board of Directors in its reasonable good faith judgment (which determination shall take into consideration any available appraisals).

If any of the amounts used to calculate the Fair Market Value are expressed in Australian dollars and not the United States dollar, then each such amount shall be converted into United States dollars based on the closing exchange rate published by the Reserve Bank of Australia in their Official Bulletin at 4 pm for the applicable date. The amounts used to calculate the Fair Market Value shall be equitably adjusted for the occurrence of any of the events for which an adjustment would be made pursuant toSection 3 but which is not otherwise fully reflected in the Fair Market Value calculation.

(d)Election to receive Common Stock. The Holder may include in their Notice of Exercise, the election to receive the corresponding number of shares of Common Stock for the Warrant CDIs to be purchased.

(e)Exercise Process including Holding Statement. In the event of the valid exercise of this Warrant, the Company must, if the CDIs are quoted on the ASX, do the following:

(i) allot and issue to CHESS Depositary Nominees Pty Ltd (“CDN”)the number of shares of Common Stock underlying the CDIs the subject of the Notice of Exercise and procure CDN to allot and issue to the Holder the number of CDIs representing the Common Stock issued to CDN under this provision;

- 2��-

(ii) enter CDN into the Company’s register of members as the holder of the relevant number of shares of Common Stock and procure CDN to enter the Holder into the register of CDI holders as the holder of the relevant number of CDIs;

(iii) deliver to the Holder a holding statement showing the Holder as the holder of the relevant number of CDIs;

(iv) apply for, and use its reasonable efforts to obtain, official quotation of the relevant number of CDIs (and underlying shares of Common Stock) on ASX as soon as practicable; and

(v) deliver in accordance withSection 6 to the Holder a check payable to the Holder for any cash amounts payable as a result of any fractional shares.

If, at the time of exercise, CDIs are no longer quoted on ASX, then on exercise of the Warrant the Company must issue directly to the Holder the number of shares of Common Stock over which the Warrant is exercised and must procure that those shares be listed for trading on any securities exchange on which the Company’s Common Stock is tradeable and in accordance withSection 6 deliver to the Holder a check payable to Holder for any cash amounts payable as a result of any fractional shares.

3. Stock Fully Paid; Reservation of Shares. All of the Warrant CDIs or Common Stock issuable upon the exercise of this Warrant, upon issuance and receipt by the Company of the Exercise Price therefor (or upon Net Exercise thereof, as provided inSection 2(c)), shall be fully paid and nonassessable, and free from all preemptive rights, rights of first refusal or first offer, taxes, liens and charges with respect to the issuance thereof except as noted inSection 5. During the period within which the rights represented by this Warrant may be exercised, the Company shall at all times have authorized and reserved for issuance a sufficient number of shares of its Common Stock to provide for the exercise of this Warrant.

4. Adjustment of Exercise Price and Number of Shares. The number and kind of Warrant CDIs to be issued upon the exercise of this Warrant and the Exercise Price payable therefor shall be subject to adjustment from time to time upon the occurrence of certain events, as follows:

(a)Reclassification, Consolidation or Reorganization. Subject toSection 10, in case of any reclassification of the CDIs (other than as a result of a subdivision or combination), or in case of any consolidation or merger of the Company with or into another corporation or sale of all or substantially all of the Company’s assets (any of which is a “Reorganization Transaction”), the Company, or such successor corporation as the case may be, shall execute a new warrant, providing that the Holder shall have the right to exercise such new warrant, and procure upon such exercise and payment of the same aggregate Exercise Price, in lieu of the Warrant CDIs then issuable upon exercise of this Warrant, the kind and amount of shares of stock, other securities, money and property as would be received by the Holder for such Warrant CDIs as if such Warrant CDIs were outstanding immediately prior to the consummation of the Reorganization Transaction.

(b)Stock Splits, Dividends and Combinations. Subject toSection 10, in the event that the Company shall at any time subdivide the outstanding shares of Common Stock, or shall issue a stock dividend on its outstanding shares of Common Stock, the number of Warrant CDIs issuable upon exercise of this Warrant immediately prior to such subdivision or to the issuance of such stock dividend shall be proportionately increased and the Exercise Price shall be proportionately decreased, and in the event that the Company shall at any time combine the outstanding shares of Common Stock, the number of Warrant CDIs issuable upon exercise of this Warrant immediately prior to such combination shall be proportionately decreased and the Exercise Price shall be proportionately increased, effective at the close of business on the date of such subdivision, stock dividend or combination, as the case may be such that in each case, the result obtained bymultiplying the Exercise Price by the number of Warrant CDIs shall be the same immediately prior to, and immediately after, such event.

(c)Notice of Corporate Action. If the Company (i) declares a dividend (other than a cash dividend payable out of earnings or earned surplus legally available for the payment of dividends under the laws of the jurisdiction of incorporation of the Company) or other distribution, or any right to subscribe for or purchase any evidences of its indebtedness, any shares of stock of any class or any other securities or property, or to receive any other right; (ii) authorizes and publicly approves, or enters into any agreement contemplating or solicits stockholder approval for any Reorganization Transaction; or (iii) publicly authorizes the voluntary dissolution, liquidation or winding up of the affairs of the Company, then the Company shall deliver to the Holder a notice describing the material terms and conditions of such transaction, at least ten (10) business days prior to the applicable record or effective date on which a person

- 3 -

would need to hold Common Stock or CDIs in order to participate in or vote with respect to such transaction, and the Company will take all steps reasonably necessary in order to insure that the Holder is given the practical opportunity to exercise this Warrant prior to such time so as to participate in or vote with respect to such transaction. Each such written notice shall be sufficiently given if addressed to the Holder at the last address of the Holder appearing on the books of the Company and delivered in accordance withSection 11(d); provided, however, that the failure to deliver such notice or any defect therein shall not affect the validity of the corporate action required to be described in such notice.

(d)Subsequent Equity Sales. Notwithstanding any provision of this Warrant to the contrary, in the event that the Company issues any CDIs or Common Stock or any security that is exchangeable or convertible into CDIs or Common Stock (“Additional Securities”) after the date hereof at a price per CDI (or the equivalent for shares of Common Stock) that is less than the Exercise Price (or the equivalent for shares of Common Stock) in an equity financing, then the Exercise Price shall be reduced to the lowest price per CDI (or the equivalent for shares of Common Stock) at which any Additional Security was issued or sold or deemed to be issued or sold. The Company agrees that it will provide a notice to the Holder describing the material terms and conditions of any issuance of Additional Securities promptly after the issuance thereof. For the avoidance of doubt, the price per CDI (or the equivalent for shares of Common Stock) at which any Additional Securities are issued by the Company to the Holder after the date hereof, including, without limitation, upon conversion into CDIs or Common Stock of the Senior Secured Convertible Promissory Note, dated June 15, 2017, issued to the Holder by the Company, will have no effect on the Exercise Price.

5. Holder Representations and Warranties; Transfer and Assignment.

Before commencement of the Restricted Period, to prevent any such restricted dealings in the Restricted Securities during the Restricted Period, the Holder agrees to (i) the application of a holding lock to the Restricted Securities by the Payor’s securities registry for the Restricted Period, and (ii) enter into any other documents reasonably necessary to prevent any such restricted dealings in the Restricted Securities during the Restricted Period.

(c) The Holder may not sell or transfer this Warrant, or grant, issue or transfer interests in, or options over, this Warrant at any time within 12 months after the Issue Date except as permitted by section 708 or any other applicable section of theCorporations Act 2001(Cth).

The Holder shall not be entitled to vote or receive dividends or subscription rights or be deemed the holder of the CDIs, Common Stock or any other securities of the Company which may at any time be issuable on the exercise of this Warrant for any purpose, nor shall anything contained herein be construed to confer upon the Holder any of the rights of a stockholder of the Company or any right to vote for the election of directors or upon any matter submitted to stockholders at any meeting thereof, or to give or withhold consent to any corporate action (whether upon any recapitalization, issuance of stock, reclassification of stock, change of par value, consolidation, merger, conveyance, or otherwise) with respect to the Warrant CDIs until this Warrant shall have been exercised and the Warrant CDIs purchasable upon the exercise of this Warrant shall have become deliverable, as provided in Section 2(a).

SENIOR SECURED CONVERTIBLE PROMISSORY NOTE

US$5,000,000	June         , 2017
	Boston, Massachusetts

FOR VALUE RECEIVED, GI DYNAMICS, INC., a Delaware corporation (“Payor”), hereby promises to pay to the order ofCRYSTAL AMBER FUND LIMITED(the “Holder”), the principal sum of Five Million dollars (US$5,000,000) with interest on the outstanding principal amount at the rate of five percent (5%) per annum, compounded annually based on a 365-day year. Interest shall commence with the date hereof and shall continue on the outstanding principal until paid in full or, if permitted by the terms of the Note, converted pursuant toSection 2 below.

1. PAYMENTAND MATURITY

(a) Reference is hereby made to the Note Purchase Agreement (the “Purchase Agreement”) dated as of even date herewith between Payor and Holder. Capitalized terms used herein and not otherwise defined herein shall have the respective meanings given to them in the Purchase Agreement.

(b) If this Senior Secured Convertible Promissory Note (this “Note”) has not already been paid in full or, if permitted by the terms of this Note, converted in accordance with the terms ofSection 2(a), 2(b) or 2(c)below, the entire outstanding principal balance of this Note and all unpaid accrued interest thereon shall be due and payable on December 31, 2018 (the “Maturity Date”). All payments of interest and principal shall be in lawful money of the United States of America. All payments shall be applied first to accrued interest, and thereafter to principal. If any payments on this Note become due on a Saturday, Sunday or a public holiday under the laws of the State of New York, such payment shall be made on the next succeeding business day and such extension of time shall be included in computing interest in connection with such payment.

(c) Upon the occurrence and during the continuance of any Event of Default, the principal balance of this Note shall bear interest at the rate of eight percent (8%) per annum, including after the commencement of, and during the pendency of, any bankruptcy or other insolvency proceeding.

2. CONVERSION

(a)Automatic Conversion upon Qualified Financing. Subject toSection 2(d) hereof, if, at any time prior to December 31, 2018, Payor issues and sells shares of its common stock, par value $0.01 per share (the “Common Stock”) or CHESS Depositary Interests (with each CDI representing 1/50th of a share of Common Stock) (“CDIs”) to investors (the “Investors”) in a Qualified Financing (as defined herein) and this Note has not been paid in full, then the entire unpaid principal amount of this Note, together with any interest accrued but unpaid thereon (such principal amount and interest, the “Outstanding Amount”), shall automatically convert into CDIs at a conversion price (the “Conversion Price”) equal to the price per CDI of the CDIs issued and sold at such Qualified Financing (or, if only Common Stock is issued and sold in such Qualified Financing, a conversion price equal to the price per share of such Common Stock proportionately adjusted to reflect the ratio of CDIs to Common Stock in effect at the time of such Qualified Financing or, if another security of the Payor is issued and sold in such Qualified Financing, a conversion price equal to the price of such security proportionately adjusted

2

to reflect the ratio of CDIs to such security in effect at the time of such Qualified Financing). “Qualified Financing” means a round of equity financing of Common Stock or CDIs in a single transaction or a series of related transactions involving the issuance of the Payor’s securities to one or more investors which raises gross proceeds to the Payor of at least $10,000,000 in the aggregate (excluding proceeds from this Note). Subject toSection 2(d) hereof, the number of CDIs to be issued upon such conversion shall be equal to the quotient obtained by dividing (i) the Outstanding Amount by (ii) the price per CDI rounded to the nearest whole CDI. Upon such conversion, the Holder will execute such agreements as may be entered into by purchasers of CDIs, shares of Common Stock or other securities, as applicable, in the Qualified Financing generally. For the avoidance of doubt, no Investor in such Qualified Financing shall receive rights or preferences that are more favorable than those provided to the Holder.

(b)Optional Conversion. Subject toSection 2(d) andSection 6(c) of this Note, the Holder shall have the option (the “Conversion Option”), but not the obligation, at any time after the date hereof and prior to December 31, 2018, exercisable upon written notice to the Payor, to (a) convert all (but not less than all) of the Outstanding Amount into the number of CDIs equal to the quotient obtained by dividing (x) the Outstanding Amount by (y) the price per CDI equal to the volume weighted average bid closing price of the Payor’s CDIs on the Australian Securities Exchange (the “ASX”) for the five (5) trading days ending immediately prior to business day that the Payor’s receipt of the Holder’s written notice to convert (regardless if received during the trading hours or after) (such conversion price, the “CO Conversion Price”).

(c)Change of Control. Upon the consummation of a Change of Control (that is not the result of a Qualified Financing) prior to December 31, 2018 in which the Payor’s stockholders receive cash consideration, the Holder shall receive an amount in cash equal to all unpaid interest that has accrued to date hereunder and 110% of the entire unpaid principal amount of this Note in full satisfaction of all obligations under the Note. Upon the consummation of a Change of Control (that is not the result of a Qualified Financing) prior to December 31, 2018 in which the consideration received by the Payor’s stockholders consists of non-cash consideration, including, without limitation, securities, the Holder shall, subject toSection 2(d) hereof, have the Conversion Option set forth inSection 2(b) hereof. A “Change of Control” means any transaction or series of related transactions that could result in any of the following: (i) the sale of all or substantially all of the assets of the Payor to any person or related group of persons (other than the Holder or a person that directly or indirectly controls, is controlled by, or is under common control with, the Holder), (ii) the acquisition, directly or indirectly, by any person or related group of persons (other than the Payor or the Holder or a person that directly or indirectly controls, is controlled by, or is under common control with, the Payor or the Holder) of beneficial ownership of securities possessing more than fifty percent (50%) of the total combined voting power of the Payor’s outstanding securities pursuant to a tender or exchange offer made directly to the Payor’s stockholders, (iii) a merger or consolidation of the Payor, other than for the purpose of re-domiciling the Payor, unless following such transaction or series of transactions, the holders of the Payor’s securities prior to the first such transaction continue to hold more than fifty percent (50% percent) of the voting rights and equity interests in the surviving entity, (iv) a recapitalization, reorganization or other transaction involving the Payor that constitutes or results in a transfer of more than one-third of the equity interests in the Payor, unless following such transaction or series of transactions, the holders of the Payor’s securities prior to the first such transaction continue to hold more than fifty percent (50%) of the voting rights and equity interests in the surviving entity or acquirer or (v) the execution by the Payor or its controlling stockholders of an agreement providing for or reasonably likely to result in any of the foregoing events.

(d)Stockholder Approval. Notwithstanding anything to the contrary contained herein or in the Note Purchase Agreement, in the event that the rules of the ASX (or any other exchange on which the CDIs or Common Stock is then traded) require the Payor to obtain stockholder approval to issue CDIs pursuant toSection 2(a) orSection 2(b) orSection 2(c) hereof, the Payor shall convene a meeting of stockholders to seek approval to issue those CDIs or Common Stock. If such approval is not obtained at such meeting, the Holder shall instead become entitled to receive an amount in cash equal to all unpaid (and unconverted) interest that has accrued to date hereunder and 110% of the entire unpaid (and unconverted) principal amount of this Note in full satisfaction of all obligations under the Note, and such amounts shall be due and payable upon the earlier of (i) the Maturity Date, or (ii) the date that is six months following the date of the stockholders’ meeting at which such approval is not obtained. For the avoidance of doubt, while the Payor is listed on the ASX and the rules of the ASX require the Payor to obtain stockholder approval to issue CDIs, no conversion may occur under this Note, and no CDIs or Common Stock may be issued pursuant toSection 2(a) orSection 2(b) orSection 2(c)hereof, unless and until the Payor has obtained stockholder approval pursuant to thisSection 2(d).

(e)Fractional Shares. No fractional shares of Payor’s capital stock will be issued upon conversion of this Note. In lieu of any fractional share to which Holder would otherwise be entitled, Payor will pay to Holder in

3

cash the amount of the unconverted principal and interest balance of this Note that would otherwise be converted into such fractional share. Upon conversion of this Note pursuant toSection 2, Holder shall surrender this Note, duly endorsed, at the principal offices of Payor. At its expense, Payor will, as soon as practicable thereafter, issue and deliver to Holder, at Holder’s address set forth on the first page hereto or such other address requested by Holder, a certificate or certificates or holding statement (as applicable) for the number of shares of Common Stock or CDIs to which Holder is entitled upon such conversion, together with any other securities and property to which Holder is entitled upon such conversion under the terms of this Note, including a check payable to Holder for any cash amounts payable as a result of any fractional shares as described herein.

(f)Holder Representations and Warranties; Transfer and Assignment. The representations and warranties and rights and obligations of transfer and assignment of Holder that are set forth inSection 4 of the Purchase Agreement with respect to the shares of Common Stock or CDIs issuable to Holder are hereby made a part of this Note and incorporated herein by this reference.

(g)Restriction on Transfer. Notwithstanding any other provision of this Note, the Purchase Agreement or the Security Agreement, the Holder may not sell or transfer any shares of Common Stock or CDIs issued to the Holder pursuant toSection 2(a) orSection 2(b) orSection 2(c) hereof (“Restricted Securities”), or grant, issue or transfer interests in, or options over, any Restricted Securities, at any time within 12 months after the issue of those Restricted Securities (“Restricted Period”) except as permitted by section 708 or any other applicable section of theCorporations Act 2001 (Cth). Before commencement of the Restricted Period, to prevent any such restricted dealings in the Restricted Securities during the Restricted Period, the Holder agrees to (i) the application of a holding lock to the Restricted Securities by the Payor’s securities registry for the Restricted Period, and (ii) enter into any other documents reasonably necessary to prevent any such restricted dealings in the Restricted Securities during the Restricted Period.

(b) Upon the occurrence and during the continuance of any Event of Default, all unpaid principal on this Note, accrued and unpaid interest thereon and all other amounts owing hereunder shall, at the option of the Holder, and, upon the occurrence of any Event of Default pursuant to Sections 5.1(b), (c) or (d) of the Purchase Agreement, automatically, be immediately due, payable and collectible by Holder pursuant to applicable law. Subject to Section 5(c) of the Security Agreement dated as of the date hereof between the Payor and the Holder (“Security Agreement”), the Holder shall have all rights and may exercise all remedies available to it under law, successively or concurrently.

(c) Upon the occurrence and during the continuance of any Event of Default, Payor shall pay, on demand, all reasonable attorneys’ fees and court costs incurred by Holder in enforcing and collecting this Note.

5. NON-TRANSFERABLE.The Holder may not sell or transfer this Note, or grant, issue or transfer interests in, or options over, this Note at any time within 12 months after the date hereof except as permitted by section 708 or any other applicable section of theCorporations Act 2001 (Cth).

6. FUNDAMENTAL TRANSACTIONS; CORPORATE EVENTS.

Subject to the provisions ofSection 2(c) hereof, the terms of any agreement pursuant to which a Fundamental Transaction is effected shall include terms requiring any such successor or surviving entity to comply with the provisions of this paragraph (c) and insuring that this Note (or any such replacement security) will be similarly adjusted upon any subsequent transaction analogous to a Fundamental Transaction.

(i) The Secured Party may collect and receive all income and proceeds in respect of the Collateral and exercise all rights of the Debtor with respect thereto.

Any surplus remaining after such application shall be paid to the Debtor or to whomever may be legally entitled thereto, provided that in no event shall the Debtor be credited with any part of the proceeds of the disposition of the Collateral until such proceeds shall have been received in cash by the Secured Party.

(c) Notwithstanding anything to the contrary contained herein, if an Event of Default occurs and the Secured Party exercises its rights under this Security Agreement, neither the Secured Party nor any of its associates can acquire any legal or beneficial interest in the Collateral in full or part satisfaction of the Debtor’s obligations under this Security Agreement, or otherwise deal with the assets of the Debtor or its subsidiaries, without the Debtor first having complied with any applicable Listing Rules of the Australian Securities Exchange (the “ASX”), including ASX Listing Rule 10.1, other than as required by law or through a receiver, or receiver or manager (or analogous person) appointed by the Secured Party exercising its power of sale under this Security Agreement and selling the Collateral to an unrelated third party on arm’s length commercial terms and conditions and distributing the cash proceeds to the Secured Party or any of its associates in accordance with their legal entitlements.

With respect to both the Obligations and the Collateral, the Debtor assents to any extension or postponement of the time of payment or any other forgiveness or indulgence, to any substitution, exchange or release of Collateral, to the addition or release of any party or person primarily or secondarily liable, to the acceptance of partial payment thereon and the settlement, compromise or adjustment of any thereof, all in such manner and at such time or times as the Secured Party may deem advisable. Upon the occurrence of an Event of Default that remains continuing the Secured Party may, subject to Section 5(c) hereof, exercise its rights with respect to the Collateral without resorting, or regard, to other collateral or sources of reimbursement for Obligations. The Secured Party shall not be deemed to have waived any of its rights with respect to the Obligations or the Collateral unless such waiver is in writing and signed by the Secured Party. No

4

delay or omission on the part of the Secured Party in exercising any right shall operate as a waiver of such right or any other right. A waiver on any one occasion shall not bar or waive the exercise of any right on any future occasion.

Section 9.General. This Agreement may not be amended or modified except by a written instrument signed by the Debtor and the Secured Party, nor may the Debtor assign any of its rights hereunder. Further, while the terms of any waiver granted by ASX in respect of this Agreement, the Promissory Note or the Note Purchase Agreement remains applicable to the Debtor, any variation to the terms of this Agreement which is not a minor change or which is inconsistent with the terms of any relevant waiver granted by ASX to the Debtor must be approved by the Debtor’s ordinary securityholders. Section headings are for convenience of reference only and are not a part of this Agreement. This Agreement shall be binding upon the Debtor, its successors and assigns, and shall inure to the benefit of and be enforceable by the Secured Party.

SENIOR SECURED CONVERTIBLE PROMISSORY NOTE

US$5,000,000	June 15, 2017
	Boston, Massachusetts

FORVALUERECEIVED, GI DYNAMICS, INC., a Delaware corporation (“Payor”), hereby promises to pay to the order ofCRYSTAL AMBER FUND LIMITED(the “Holder”), the principal sum of Five Million dollars (US$5,000,000) with interest on the outstanding principal amount at the rate of five percent (5%) per annum, compounded annually based on a 365-day year. Interest shall commence with the date hereof and shall continue on the outstanding principal until paid in full or, if permitted by the terms of the Note, converted pursuant toSection 2 below.

1. PAYMENTAND MATURITY

(a) Reference is hereby made to the Note Purchase Agreement (the “Purchase Agreement”) dated as of even date herewith between Payor and Holder. Capitalized terms used herein and not otherwise defined herein shall have the respective meanings given to them in the Purchase Agreement.

(b) If this Senior Secured Convertible Promissory Note (this “Note”) has not already been paid in full or, if permitted by the terms of this Note, converted in accordance with the terms ofSection 2(a), 2(b) or 2(c) below, the entire outstanding principal balance of this Note and all unpaid accrued interest thereon shall be due and payable on December 31, 2018 (the “Maturity Date”). All payments of interest and principal shall be in lawful money of the United States of America. All payments shall be applied first to accrued interest, and thereafter to principal. If any payments on this Note become due on a Saturday, Sunday or a public holiday under the laws of the State of New York, such payment shall be made on the next succeeding business day and such extension of time shall be included in computing interest in connection with such payment.

(c) Upon the occurrence and during the continuance of any Event of Default, the principal balance of this Note shall bear interest at the rate of eight percent (8%) per annum, including after the commencement of, and during the pendency of, any bankruptcy or other insolvency proceeding.

2. CONVERSION

(a)Automatic Conversion upon Qualified Financing. Subject to Section 2(d) hereof, if, at any time prior to December 31, 2018, Payor issues and sells shares of its common stock, par value $0.01 per share (the “Common Stock”) or CHESS Depositary Interests (with each CDI representing 1/50th of a share of Common Stock) (“CDIs”) to investors (the “Investors”) in a Qualified Financing (as defined herein) and this Note has not been paid in full, then the entire unpaid principal amount of this Note, together with any interest accrued but unpaid thereon (such principal amount and interest, the “Outstanding Amount”), shall automatically convert into CDIs at a conversion price (the “Conversion Price”) equal to the price per CDI of the CDIs issued and sold at such Qualified Financing (or, if only Common Stock is issued and sold in such Qualified Financing, a conversion price equal to the price per share of such Common Stock proportionately adjusted to reflect the ratio of CDIs to Common Stock in effect at the time of such Qualified Financing or, if another security of the Payor is issued and sold in such Qualified Financing, a conversion price equal to the price of such security proportionately adjusted to reflect the ratio of CDIs to such security in effect at the time of such Qualified Financing). “Qualified Financing” means a round of equity financing of Common Stock or CDIs in a single transaction or a series of

1

related transactions involving the issuance of the Payor’s securities to one or more investors which raises gross proceeds to the Payor of at least $10,000,000 in the aggregate (excluding proceeds from this Note). Subject toSection 2(d) hereof, the number of CDIs to be issued upon such conversion shall be equal to the quotient obtained by dividing (i) the Outstanding Amount by (ii) the price per CDI rounded to the nearest whole CDI. Upon such conversion, the Holder will execute such agreements as may be entered into by purchasers of CDIs, shares of Common Stock or other securities, as applicable, in the Qualified Financing generally. For the avoidance of doubt, no Investor in such Qualified Financing shall receive rights or preferences that are more favorable than those provided to the Holder.

(b)Optional Conversion. Subject toSection 2(d) andSection 6(c) of this Note, the Holder shall have the option (the “Conversion Option”), but not the obligation, at any time after the date hereof and prior to December 31, 2018, exercisable upon written notice to the Payor, to (a) convert all (but not less than all) of the Outstanding Amount into the number of CDIs equal to the quotient obtained by dividing (x) the Outstanding Amount by (y) the price per CDI equal to the volume weighted average bid closing price of the Payor’s CDIs on the Australian Securities Exchange (the “ASX”) for the five (5) trading days ending immediately prior to business day that the Payor’s receipt of the Holder’s written notice to convert (regardless if received during the trading hours or after) (such conversion price, the “CO Conversion Price”).

(c)Change of Control. Upon the consummation of a Change of Control (that is not the result of a Qualified Financing) prior to December 31, 2018 in which the Payor’s stockholders receive cash consideration, the Holder shall receive an amount in cash equal to all unpaid interest that has accrued to date hereunder and 110% of the entire unpaid principal amount of this Note in full satisfaction of all obligations under the Note. Upon the consummation of a Change of Control (that is not the result of a Qualified Financing) prior to December 31, 2018 in which the consideration received by the Payor’s stockholders consists of non-cash consideration, including, without limitation, securities, the Holder shall, subject toSection 2(d) hereof, have the Conversion Option set forth inSection 2(b) hereof. A “Change of Control” means any transaction or series of related transactions that could result in any of the following: (i) the sale of all or substantially all of the assets of the Payor to any person or related group of persons (other than the Holder or a person that directly or indirectly controls, is controlled by, or is under common control with, the Holder), (ii) the acquisition, directly or indirectly, by any person or related group of persons (other than the Payor or the Holder or a person that directly or indirectly controls, is controlled by, or is under common control with, the Payor or the Holder) of beneficial ownership of securities possessing more than fifty percent (50%) of the total combined voting power of the Payor’s outstanding securities pursuant to a tender or exchange offer made directly to the Payor’s stockholders, (iii) a merger or consolidation of the Payor, other than for the purpose of re-domiciling the Payor, unless following such transaction or series of transactions, the holders of the Payor’s securities prior to the first such transaction continue to hold more than fifty percent (50% percent) of the voting rights and equity interests in the surviving entity, (iv) a recapitalization, reorganization or other transaction involving the Payor that constitutes or results in a transfer of more than one-third of the equity interests in the Payor, unless following such transaction or series of transactions, the holders of the Payor’s securities prior to the first such transaction continue to hold more than fifty percent (50%) of the voting rights and equity interests in the surviving entity or acquirer or (v) the execution by the Payor or its controlling stockholders of an agreement providing for or reasonably likely to result in any of the foregoing events.

(d)Stockholder Approval. Notwithstanding anything to the contrary contained herein or in the Note Purchase Agreement, in the event that the rules of the ASX (or any other exchange on which the CDIs or Common Stock is then traded) require the Payor to obtain stockholder approval to issue CDIs pursuant toSection 2(a) orSection 2(b) orSection 2(c) hereof, the Payor shall convene a meeting of stockholders to seek approval to issue those CDIs or Common Stock. If such approval is not obtained at such meeting, the Holder shall instead become entitled to receive an amount in cash equal to all unpaid (and unconverted) interest that has accrued to date hereunder and 110% of the entire unpaid (and unconverted) principal amount of this Note in full satisfaction of all obligations under the Note, and such amounts shall be due and payable upon the earlier of (i) the Maturity Date, or (ii) the date that is six months following the date of the stockholders’ meeting at which such approval is not obtained. For the avoidance of doubt, while the Payor is listed on the ASX and the rules of the ASX require the Payor to obtain stockholder approval to issue CDIs, no conversion may occur under this Note, and no CDIs or Common Stock may be issued pursuant toSection 2(a) orSection 2(b) orSection 2(c) hereof, unless and until the Payor has obtained stockholder approval pursuant to thisSection 2(d).

(e)Fractional Shares. No fractional shares of Payor’s capital stock will be issued upon conversion of this Note. In lieu of any fractional share to which Holder would otherwise be entitled, Payor will pay to Holder in cash the amount of the unconverted principal and interest balance of this Note that would otherwise be converted

2

into such fractional share. Upon conversion of this Note pursuant toSection 2, Holder shall surrender this Note, duly endorsed, at the principal offices of Payor. At its expense, Payor will, as soon as practicable thereafter, issue and deliver to Holder, at Holder’s address set forth on the first page hereto or such other address requested by Holder, a certificate or certificates or holding statement (as applicable) for the number of shares of Common Stock or CDIs to which Holder is entitled upon such conversion, together with any other securities and property to which Holder is entitled upon such conversion under the terms of this Note, including a check payable to Holder for any cash amounts payable as a result of any fractional shares as described herein.

(f)Holder Representations and Warranties; Transfer and Assignment. The representations and warranties and rights and obligations of transfer and assignment of Holder that are set forth inSection 4 of the Purchase Agreement with respect to the shares of Common Stock or CDIs issuable to Holder are hereby made a part of this Note and incorporated herein by this reference.

(g)Restriction on Transfer. Notwithstanding any other provision of this Note, the Purchase Agreement or the Security Agreement, the Holder may not sell or transfer any shares of Common Stock or CDIs issued to the Holder pursuant toSection 2(a) orSection 2(b) orSection 2(c) hereof (“Restricted Securities”), or grant, issue or transfer interests in, or options over, any Restricted Securities, at any time within 12 months after the issue of those Restricted Securities (“Restricted Period”) except as permitted by section 708 or any other applicable section of theCorporations Act 2001 (Cth). Before commencement of the Restricted Period, to prevent any such restricted dealings in the Restricted Securities during the Restricted Period, the Holder agrees to (i) the application of a holding lock to the Restricted Securities by the Payor’s securities registry for the Restricted Period, and (ii) enter into any other documents reasonably necessary to prevent any such restricted dealings in the Restricted Securities during the Restricted Period.

3. DEFAULT; REMEDIES

(a) The occurrence of any Event of Default described in Section 5.1 of the Purchase Agreement shall be an Event of Default hereunder.

(b) Upon the occurrence and during the continuance of any Event of Default, all unpaid principal on this Note, accrued and unpaid interest thereon and all other amounts owing hereunder shall, at the option of the Holder, and, upon the occurrence of any Event of Default pursuant to Sections 5.1(b), (c) or (d) of the Purchase Agreement, automatically, be immediately due, payable and collectible by Holder pursuant to applicable law. Subject to Section 5(c) of the Security Agreement dated as of the date hereof between the Payor and the Holder (“Security Agreement”), the Holder shall have all rights and may exercise all remedies available to it under law, successively or concurrently.

(c) Upon the occurrence and during the continuance of any Event of Default, Payor shall pay, on demand, all reasonable attorneys’ fees and court costs incurred by Holder in enforcing and collecting this Note.

5. NON-TRANSFERABLE.The Holder may not sell or transfer this Note, or grant, issue or transfer interests in, or options over, this Note at any time within 12 months after the date hereof except as permitted by section 708 or any other applicable section of theCorporations Act 2001 (Cth).

6. FUNDAMENTAL TRANSACTIONS; CORPORATE EVENTS.

(a)Fundamental Transactions. If, at any time while this Note is outstanding, (i) the Payor effects any merger or consolidation of the Payor with or into another person pursuant to which the Common Stock is effectively converted and exchanged, (ii) the Payor effects any sale of all or substantially all of its assets in one or a series of related transactions pursuant to which the Common Stock is effectively converted and exchanged, (iii) any tender offer or exchange offer (whether by the Payor or another person) is completed pursuant to which at least a majority of the outstanding Common Stock is tendered and exchanged for other securities, cash or property or (iv) the Payor effects any reclassification of the Common Stock or any compulsory share exchange pursuant to which the Common Stock is effectively converted into or exchanged for other securities, cash or property (other than as a result of a subdivision or combination of shares of Common Stock covered bySection 5(a) above) (in any such case, a “Fundamental Transaction”), then prior to any subsequent conversion of this Note, and subject to the provisions ofSection 2(c) hereof, the Holder shall be entitled to require the surviving entity to issue to the Investor an instrument identical to this Note (with an appropriate adjustment to the

3

conversion price(s)) such that the Holder may receive stock (or a beneficial interest in stock) of the surviving company’s stock.

(c)Subsequent Equity Sales.

(i) For a period of time (the “Specified Expiration Period”) commencing on the date of the closing of the issuance of the Additional Securities and expiring on the date that is thirty (30) days after the date that Payor delivers a notice (such notice being an “Additional Securities Notice”) describing the material terms and conditions of such transaction (but in any event, not less than 30 days after the issuance of the Additional Securities), the CO Conversion Price shall be reduced so that during such period it will not be more than an amount (the “CO Maximum Amount”) equal to the following: Existing Conversion Price * (A+B) / (A+C).

(2)“B” shall mean the aggregate cash consideration received by Payor at the closing of the issuance of Additional Securities (together with such additional cash amounts payable with respect to any exercise or conversion of Additional Securities for shares of Common Stock or CDIs if such amount is then less than the Existing Conversion Price) divided by the Existing Conversion Price.

(3)“C” shall mean the number of CDIs underlying the Additional Securities in such issuance, including for this purpose the number CDIs representing number of shares of Common Stock underlying such Additional Securities (with each CDI representing 1/50th of a share of Common Stock).

(5)“Pre Sale Pro Rata Percentage” shall mean a percentage equal to (x) the number of CDIs that are owned by the Holder (excluding the CDIs or shares of Common Stock underlying this Note) immediately prior to the issuance of the Additional Securities (the “Holder’s Existing Ownership”); (y) divided by A, which for purposes hereof excludes securities issuable upon conversion of the Note.

(6)“Post Sale CDIs” shall mean the number of CDIs outstanding determined on a fully diluted basis (including the CDIs or shares of Common Stock underlying this Note that become exercisable

4

pursuant to clause (iv) below) and including for this purpose the number CDIs representing the number of shares of Common Stock underlying such Additional Securities (with each CDI representing 1/50^th of a share of Common Stock).

(iii) The Payor agrees that it will provide each Additional Securities Notice to the Holder promptly after the issuance of Additional Securities, including a calculation in reasonable detail of the CO Maximum Amount.

Payor waives presentment and demand for payment, notice of dishonor, protest and notice of protest of this Note, and shall pay all costs of collection when incurred, including, without limitation, reasonable attorneys’ fees, costs and other expenses.

No delay by Holder shall constitute a waiver, election or acquiescence by it.

8. CUMULATIVE REMEDIES. Holder’s rights and remedies under this Note, the Purchase Agreement and the Security Agreement shall be cumulative. No exercise by Holder of one right or remedy shall be deemed an election, and no waiver by Holder of any Event of Default shall be deemed a continuing waiver of such Event of Default or the waiver of any other Event of Default.

Annex D

Annexure D—Summary of the 2017 Convertible Note Terms

The key terms of the 2017 Convertible Note are as follows:

b. Lender/ Holder: Crystal Amber Fund Limited

c. Principal Amount/ Face Value: US $5,000,000

d. Interest: 5% per annum, compounded annually (increasing to 8% per annum in the event of default)

e. Conversion:Subject to the receipt of shareholder approval (for the purposes of, among others, ASX Listing Rule 10.11), the Principal Amount is convertible into CHESS Depositary Interests (CDIs) (i) at the option of the Lender (based on a5-day VWAP) or (ii) automatically on the occurrence of a “qualified financing” (essentially a further equity raising of at least US $10 million). In the event that the Borrower issues additional CDIs in a subsequent equity raising at a price per CDI that is less than the then-effective optional conversion price (based on a5-day VWAP), the Lender has a30-day option to convert (if the abovementioned shareholder approval of the right of conversion has been/is obtained) at an adjusted conversion price reflecting, on a weighted average basis, the lower price per CDI. The number of CDIs that the Lender may acquire upon conversion of the loan at this adjusted conversion price is limited to the number that maintains the Lender’s fully-diluted ownership percentage of GI Dynamics at the same level as existed immediately preceding the applicable subsequent equity raising. If shareholder approval of the right of conversion is not obtained the loan will not be convertible into CDIs

f. Security:All of the Borrower’s right, title and interest in, to and under all of GID’s assets. However, until approval from stockholders for the purposes of ASX Listing Rule 10.1 is obtained, the security provisions include a term that if an event of default occurs, and the Lender exercises its right to enforce the security, neither the Lender or any of its subsidiaries may otherwise deal with the assets of GID or its subsidiaries, other than as required by law or through a receiver, or manager (or analogous person) appointed by the Lender exercising their power of sale under the Security and selling the assets to an unrelated third party on arm’s length commercial terms and conditions and distributing the cash proceeds to the Lender or any of its associates

g. Maturity/ Repayment: 31 December 2018 or if shareholder approval in relation to the right of conversion (referred to in paragraph (e) above) is not obtained then the earlier of 31 December 2018 and the date 6 months after the date on which shareholder approval of the right of conversion is not obtained. If shareholder approval is not obtained, the Lender is entitled to receive 110% of the unpaid principal plus unpaid interest (by way of repayment)

h. Change of Control of GID: Where GID shareholders receive cash consideration on completion of a change of control transaction, the Lender is entitled to receive 110% of the unpaid principal plus unpaid interest. Where GID shareholders receive scrip consideration on completion of a change of control transaction, the Lender is entitled (subject to the shareholder approval referred to in paragraph (e) above being obtained) to exercise the conversion option (relevant to paragraph (e) above)

i. Prepayments: Not permitted without the Lender’s consent

j. Transferability/Assignability:The convertible note is not transferrable / assignable within 12 months after its issue, except as permitted by the Corporations Act 2001 (Cth)

k. Transfer of CDIs issued on conversion: Any CDIs issued on a conversion are not transferrable within 12 months after their issue (and the CDIs will be subject to a holding lock), except as permitted by the Corporations Act 2001 (Cth)

l. Events of Default: On the occurrence of an event of default, all unpaid principal plus unpaid interest generally becomes immediately due and payable

m. Use of Funds: General corporate purposes
