The Borrower represents and warrants to the Lender, and the representations and warranties are continuing representations so long as any Obligations remain outstanding and will be deemed repeated and confirmed at the time of each request for an Advance under the Loan as though made at and as of such date, as follows:

4.1 Business, Etc. The Borrower is a corporation organized, existing and in good standing under the laws of the State of Delaware and is registered to do business as a foreign corporation in each state where the Borrower is required to be so registered, except where the failure to so qualify would not be reasonably expected to have a Material Adverse Effect. The Borrower has adequate authority and has all necessary material Permits to carry on its business and is entitled to own its property and to carry on its business, all as and in the places where its property is now owned or operated and its business is conducted. The Borrower is not a member of any partnership or joint venture, and, as of the Closing Date, the Borrower has no subsidiaries other than those listed in Schedule 4.1 attached hereto.

4.2 Compliance with Legal Requirements/Litigation. The Borrower is in compliance in all material respects with all Legal Requirements governing the conduct of its business. The Borrower shall diligently pursue and obtain all material Permits necessary for the conduct of its business and the use of its properties and assets, as presently conducted, owned and used or as proposed to be conducted, owned and used. The Borrower has not received any notice, not heretofore complied with, from any Governmental Authority or any insurance, accreditation or inspection body that any of its properties, facilities, equipment, procedures or practices fails to comply in any material respect with any applicable Legal Requirement, any Permit or any other requirement of any such authority or body. No authorization, consent, approval, license, exemption of or filing or registration with any Governmental Authority is or will be necessary to the valid execution or delivery of, or for the performance by the Borrower of its obligations under, this Agreement, any of the other Loan Documents or other instrument provided for or contemplated by this Agreement, with the exception of consents and approvals heretofore obtained. Except as set forth on Schedule 4.2 attached hereto, there are no actions, suits or proceedings pending, or to the knowledge of the Borrower, threatened against or affecting the Borrower or its property in any court or before or by any Governmental Authority.

The Borrower is not in default with respect to any order, writ, injunction, decree or demand of any Governmental Authority.

4.3 Capacity. The Borrower is authorized under all applicable laws to make and perform the Loan Documents, to which it is a party, and all action on its part required for the making and performance of the Loan Documents, to which it is a party, has been taken. Each of the Loan Documents is the valid and enforceable obligation of the Borrower in accordance with its respective terms, subject to laws of general application affecting creditors’ rights. Neither the execution and delivery of the Loan Documents, nor compliance with the terms thereof, will conflict with or result in a breach of any provisions of the Borrower’s organizational documents or of any agreement to which the Borrower is now a party or by which it is bound, or constitute a default under any of the foregoing, or result in the creation of any encumbrance upon any property of the Borrower under the terms of any such agreement.

4.4 Disclosure. None of the Loan Documents and no certificate or statement furnished to the Lender by the Borrower in connection with the transactions contemplated under the Loan Documents, contains any untrue statement of a material fact or omits to state a material fact necessary in order to make the statements contained therein not misleading. There is no fact presently in existence which now affects or which the Borrower believes is likely in the future (so far as the Borrower can now reasonably foresee) to affect, in a way which is both material and adverse, the business or condition (financial or otherwise) of the Borrower its property or the property subject to the Leases, which fact has not been set forth in this Agreement or in a certificate or statement furnished to the Lender by the Borrower.

4.5 Use of Proceeds. The proceeds of the Loan are to be used for equipment purchases. No part of the proceeds of the Loan will be used for the purpose of purchasing or carrying any “margin security” as defined in Regulation U of the Board of Governors of the Federal Reserve System.

4.6 Taxes. Except as set forth on Schedule 4.6 attached hereto, the Borrower has filed all required tax returns and paid all applicable Federal, state and local taxes, other than (a) taxes not yet due or which may be paid in the future without penalty, or (b) taxes which are currently being contested in good faith by appropriate proceedings and for which the Borrower has established adequate reserves. The Borrower has no knowledge of any deficiency or additional assessment in connection with any taxes not provided for on its books.

4.7 Title to Assets. The Borrower has good, clear and marketable title to the Collateral, free of any mortgages, pledges, charges, liens, security interests or other encumbrances other than Permitted Liens. All Collateral owned by the Borrower is in good condition and working order (ordinary wear and tear excepted), and has not been damaged without restoration to Lender’s satisfaction.

4.8 Employee Benefits Plans.

4.8.1 No “reportable event” (as defined in Section 4043(b) of ERISA) (whether or not waived) has occurred or is continuing with respect to any “employee pension

benefit plan” (as defined in Section 3 of ERISA) maintained for employees of the Borrower (a “Pension Benefit Plan”).

4.8.2 No prohibited transaction (within the meaning of Section 406 of ERISA) has occurred with respect to any Pension Benefit Plan or any other “employee benefit plan” (as defined in Section 3 of ERISA) (together with a Pension Benefit Plan, an “Employee Plan”) maintained for employees of the Borrower and covered by Part 4 of the Subtitle B of Title I of ERISA.

4.8.3 With respect to each Pension Benefit Plan, the amount for which the Borrower would be liable pursuant to the provisions of Sections 4062, 4063 or 4064 of ERISA would be zero if such plans terminated on the date of this Agreement. The accumulated benefit obligation under all defined benefit plans of the Borrower was less than the fair value of the assets of those plans.

4.8.4 The Borrower is not now, nor has been during the preceding five (5) years, a contributing employer to a “multiemployer plan” (as defined in Section 4001(a)(3) of ERISA) (a “Multiemployer Plan”). The Borrower has not (a) ceased operations at a facility so as to become subject to the provisions of Section 4062(f) of ERISA, (b) withdrawn as a substantial employer so as to become subject to the provisions of Section 4063 of ERISA, (c) ceased making contributions on or before the date hereof to any Pension Benefit Plan subject to the provisions of Section 4064(a) of ERISA to which the Borrower made contributions during any of the five (5) years prior to the date hereof, (d) incurred or caused to occur a “complete withdrawal” (within the meaning of Section 4203 of ERISA) or a “partial withdrawal” (within the meaning of Section 4205 of ERISA) from a Multiemployer Plan that is a Pension Benefit Plan so as to incur withdrawal liability under Section 4201 of ERISA (without regard to subsequent reduction or waiver of such liability under Sections 4207 or 4208 of ERISA), or (e) been a party to any transaction or agreement under which the provisions of Section 4204 of ERISA were applicable.

4.8.5 No notice of intent to terminate a Pension Benefit Plan has been filed, nor has any Plan been terminated, pursuant to the provisions of Section 4041(f) of ERISA.

4.8.6 The PBGC has not instituted proceedings to terminate (or appoint a trustee to administer) a Pension Benefit Plan and no event has occurred or condition exists which might constitute grounds under the provisions of Section 4042 of ERISA for the termination of (or the appointment of a trustee to administer) any such Plan.

4.8.7 The Borrower does not maintain and has never maintained any Pension Benefit Plan that is subject to the provisions of Title I, Subtitle B, Part 3 of ERISA.

4.8.8 There are no actions, suits or claims pending (other than routine claims for benefits) or, to the knowledge of the Borrower, which could reasonably be expected to be asserted, against any Employee Plan or the assets of any such plan. No civil or criminal action brought pursuant to the provisions of Title I, Subtitle B, Part 5 of ERISA is pending or, to the best knowledge of the Borrower, threatened against any fiduciary of

any Employee Plan. None of the Employee Plans or any fiduciary thereof has been the direct or indirect subject of an audit, investigation or examination by any governmental or quasi-governmental agency.

4.8.9 All of the Employee Plans comply currently, and have complied in the past, in all material respects both as to form and operation, with their terms and with the provisions of ERISA and the Internal Revenue Code of 1986, and all other applicable laws, rules and regulations (including, but not limited to, the Tax Reform Act of 1986 and all subsequent federal legislation affecting qualified plans generally); all necessary governmental approvals for the Employee Plans have been obtained and a favorable determination as to the qualification under Section 401(a) of such Code of each of the Pension Benefit Plans and each amendment thereto has been made by the Internal Revenue Service and a recognition of exemption from federal income taxation under Section 510(a) of the Code of each of the funded welfare benefit plans within the meaning of Section 3(1) of ERISA has been made by the Internal Revenue Service, and nothing has occurred since the date of each such determination or recognition letter that would adversely affect such qualification.

4.9 Financial Statements. The Financial Statements are complete and accurate and fairly present the financial condition of the Borrower as at the dates thereof and for the periods covered thereby, and were prepared in accordance with GAAP (subject in the case of quarterly Financial Statements, to year end adjustments and the absence of footnotes). The Borrower has no liability, contingent or otherwise, which is not disclosed in the Financial Statements or in any notes thereto that could materially adversely affect the financial condition of the Borrower. The following representations are true on the date of this Agreement and shall be true at the date of each Advance, in each case since the date of the most recently delivered financial statements: (a) there has been no Material Adverse Effect; (b) neither the business, condition, or operations of the Borrower nor any of its properties or assets has been materially adversely affected as the result of any legislative or regulatory change, any revocation or change in any Permit, or any other event or occurrence, whether or not insured against; and (c) except as disclosed in writing to Lender, the Borrower has not experienced any material controversy or problem with its employees or with any labor organization that the Borrower reasonably determines may have a Material Adverse Effect on the business of the Borrower.

4.10 Environmental Compliance. To Borrower’s knowledge, Borrower has not owned, occupied or operated a site on which any Hazardous Substances were or are stored without compliance with all Environmental Laws, or disposed of, transported, or arranged for the transport of any Hazardous Substances without compliance with all Environmental Laws, or caused or been legally responsible for any release of any Hazardous Substances. To Borrower’s knowledge, Borrower and each of its properties, whether or not subject to a Lease, is now in compliance with all Environmental Laws.

4.11 Incorporated Representations and Warranties. The representations and warranties of the Borrower contained in the other Loan Documents are hereby incorporated herein by reference, and all of such representations and warranties are true and correct as of the date made (except for changes which are expressly permitted by this Agreement and the other Loan Documents).

SECTION 6

6.6 Third Party Purchaser. The Lender shall have the unrestricted right at any time or from time to time, and without the Borrower’s consent, but with notice to Borrower, to sell, assign, endorse, or transfer all or any portion of its rights and obligations hereunder to one or more financial institutions approved by the Lender (each, an “Assignee”) and, the Borrower agrees upon notice that it shall execute, or cause to be executed such documents as long as said documents do not contain and/or effectuate any material changes to the Note, Loan Agreement and all related documents, including without limitation, amendments to this Agreement and to any other documents, instruments and agreements executed in connection herewith as the Lender shall reasonably deem necessary to effect the foregoing. In addition, at the request of the Lender and any such Assignee, the Borrower shall issue one or more new promissory notes, as applicable, as long as said documents do not contain and/or effectuate any material changes to the Note, Loan Agreement and all related documents, to any such Assignee and, if the Lender has retained any of its rights and obligations hereunder following such assignment, to the Lender, which new promissory notes shall be issued in replacement of, but not in discharge of, the liability evidenced by the note held by the Lender prior to such assignment and shall reflect the amount of the respective commitments and loans held by such Assignee and the Lender after giving effect to such assignment.

All the terms, representations and warranties in this Agreement are binding upon and inure to the benefit of and are enforceable by and against the respective successors and assigns of the parties to this Agreement whether so expressed or not.

6.8 Usury. The Borrower shall not be obligated to pay and the Lender shall not collect interest at a rate higher than the maximum permitted by law or the maximum that will not subject the Lender to any civil or criminal penalties. If, because of the acceleration of maturity

the payment of interest in advance or any other reason, the Borrower is required, under the provisions of any Loan Document or otherwise, to pay interest at a rate in excess of such maximum rate, the rate of interest under such provisions shall immediately and automatically be reduced to such maximum rate and any payment made in excess of such maximum rate, together with interest thereon at the rate provided herein from the date of such payment, shall be immediately and automatically applied to the reduction of the unpaid principal balance of the Note as of the date on which such excess payment was made. If the amount to be so applied to reduction of the unpaid principal balance exceeds the unpaid principal balance, the amount of such excess shall be refunded by the Lender to the Borrower.

WARRANT TO PURCHASE
SERIES D PREFERRED STOCK OF
CONFORMIS, INC.

(Void after ,2021)

This certifies that Massachusetts Development Finance Agency, a body corporate and politic created under and acting pursuant to authority derived from Chapter 23G of the Massachusetts General Laws, as amended, or rightful assigns (the “Holder”), for value received, is entitled to purchase from ConforMIS, Inc., a Delaware corporation (the “Company”), subject to the terms set forth of this Warrant (this “Warrant”) issued as of ,2011 (the “Effective Date”), a maximum of 16,000 fully-paid and nonassessable shares (subject to adjustment as provided herein) of the Company’s Series D Preferred Stock (the “Warrant Shares”) for cash at a price of $6.00 per share (the “Exercise Price”) (subject to adjustment as provided herein) at any time or from time to time up to and including 5:00 p.m. (Massachusetts time) on the earlier of (i) a sale or exchange of all or substantially all of the assets of the Company (other than a sale or exchange to a subsidiary corporation of the Company or a sale or exchange effected for the purpose of reincorporating the Company in another jurisdiction) or the merger or consolidation of the Company with or into another entity in which the stockholders of the Company immediately prior to such transaction shall own less than a majority of the voting securities or power of the surviving entity immediately subsequent to such transaction (other than a merger or consolidation effected for the purpose of reincorporating the Company in another jurisdiction), or (ii) ,2021, such earliest day being referred to herein as the “Expiration Date,” upon surrender to the Company at its principal office (or at such other location as the Company may advise the Holder in writing) of this Warrant properly endorsed with the Form of Subscription attached hereto duly filled in and signed and upon payment in cash or by check of the aggregate Exercise Price for the number of shares for which this Warrant is being exercised determined in accordance with the provisions hereof; provided however, that if the Company conducts an initial underwritten public offering of its common stock (the “Common Stock”) pursuant to a registration statement under the Securities Act of 1933, as

amended (the “Act”), prior to the occurrence of (i) and (ii) above, the Expiration Date shall instead be the date five years after the initial closing of such initial public offering. The Exercise Price is subject to adjustment as provided in Section 3 of this Warrant.

This Warrant is subject to the following terms and conditions:

1. Exercise, Issuance of Certificates, Reduction in Number of Warrant Shares.

1.1. General. This Warrant is exercisable at the option of the Holder of record hereof on or prior to the Expiration Date, at any time or from time to time following its issuance, for all or any part of the Warrant Shares (but not for a fraction of a share) which may be purchased hereunder, as that number may be adjusted pursuant to Section 3 of this Warrant. The Company agrees that the Warrant Shares purchased under this Warrant shall be and are deemed to be issued to the Holder hereof as the record owner of such Warrant Shares as of the close of business on the date on which this Warrant shall have been surrendered, properly endorsed, the completed and executed Form of Subscription delivered, and payment made for such Warrant Shares. Certificates for the Warrant Shares so purchased, together with any other securities or property to which the Holder hereof is entitled upon such exercise, shall be delivered to the Holder hereof by the Company at the Company’s expense as soon as practicable after the rights represented by this Warrant have been so exercised. In case of a purchase of less than all of the Warrant Shares which may be purchased under this Warrant, the Company shall cancel this Warrant and execute and deliver to the Holder hereof within a reasonable time a new Warrant or Warrants of like tenor for the balance of the Warrant Shares purchasable under this Warrant surrendered upon such purchase. Each stock certificate so delivered shall be registered in the name of such Holder.

1.2. Net Issue Exercise of Warrant. Notwithstanding any provisions herein to the contrary, if the fair market value of one share of Series D Preferred Stock is greater than the Exercise Price (at the date of calculation as set forth below), in lieu of exercising this Warrant for cash, Holder may elect to receive shares of Series D Preferred Stock equal to the value (as determined below) of this Warrant (or the portion thereof being exercised) by surrender of this Warrant at the principal office of the Company together with the properly endorsed Form of Subscription in which event the Company shall issue to the Holder a number of shares of Series D Preferred Stock computed using the following formula:

	X=	Y (A-B)
		A

Where	X=	the number of shares of Series D Preferred Stock to be issued to Holder

	Y=	the number of shares of Series D Preferred Stock purchasable under this Warrant or, if only a portion of this Warrant is being exercised, the portion of this Warrant being exercised (at the date of such calculation)

	A=	the fair market value of one share of the Company’s Series D Preferred Stock (at the date of such calculation)

	B=	the Exercise Price (as adjusted to the date of such calculation)

For purposes of the above calculation, the fair market value of one share of Series D Preferred Stock shall be determined by the Company’s Board of Directors in the good faith exercise of its reasonable business judgment; provided, however, that if at the time of such exercise the Company’s Common Stock is listed on any established stock exchange or a national market system, then the fair market value per share shall be the product of (i) the average of the closing bid and asked prices of the Common Stock quoted in the over-the-counter market summary or the last reported sale price of the Common Stock or the closing price quoted on the NASDAQ National Market System or on any exchange on which the Common Stock is listed, whichever is applicable, as published in The Wall Street Journal for the five trading days prior to the date of determination of fair market value and (ii) the number of shares of Common Stock into which each share of Series D Preferred Stock is convertible at the time of such exercise. Notwithstanding the foregoing, in the event this Warrant is exercised in connection with the Company’s initial public offering of Common Stock, the fair market value per share shall be the product of (a) the per share offering price of the Common Stock to the public in the Company’s initial public offering, and (b) the number of shares of Common Stock into which each share of Series D Preferred Stock is convertible at the time of such exercise.

2. Warrant Shares to be Fully Paid; Reservation of Shares. The Company covenants and agrees that all Warrant Shares, and all shares of Common Stock issuable upon conversion of such Warrant Shares, will, upon issuance and, if applicable, payment of the applicable Exercise Price, be duly authorized, validly issued, fully paid and nonassessable, and free of all preemptive rights, liens and encumbrances, except for restrictions on transfer provided for herein or under applicable federal and state securities laws. The Company shall at all times reserve and keep available out of its authorized and unissued Series D Preferred Stock, solely for the purpose of providing for the exercise of the rights to purchase all Warrant Shares granted pursuant to this Warrant, such number of shares of Series D Preferred Stock as shall, from time to time, be sufficient therefor. The Company shall at all times reserve and keep available out of its authorized and unissued Common Stock, solely for the purpose of providing for the conversion of all of Warrant Shares issuable pursuant to this Warrant, such number of shares of Common Stock as shall, from time to time, be sufficient therefor.

3. Adjustment of Exercise Price and Number of Warrant Shares. The Exercise Price and the total number of Warrant Shares shall be subject to adjustment from time to time upon the occurrence of certain events described in this Section 3. Upon each adjustment of the Exercise Price, the Holder of this Warrant shall thereafter be entitled to purchase, at the Exercise Price resulting from such adjustment, the number of shares obtained by multiplying the Exercise Price in effect immediately prior to such adjustment by the number of shares purchasable pursuant hereto immediately prior to such adjustment, and dividing the product thereof by the Exercise Price resulting from such adjustment.

3.1. Subdivision or Combination of Stock. In the event the outstanding shares of Series D Preferred Stock shall be increased by a stock dividend, stock split, subdivision or other similar transaction occurring after the Effective Date into a greater number of shares of Series D Preferred Stock, the Exercise Price in effect immediately prior to such subdivision shall be proportionately reduced and the number of Warrant Shares issuable hereunder proportionately increased. Conversely, in the event the outstanding shares of Series D Preferred Stock shall be decreased by reverse stock split, combination, consolidation or other similar transaction occurring after the Effective Date into a lesser number of shares of Series D Preferred Stock, the Exercise Price in effect immediately prior to such combination shall be proportionately increased and the number of Warrant Shares issuable hereunder proportionately decreased.

3.2. Reclassification. If any reclassification of the capital stock of the Company (in one transaction or a series of related transactions) (a “Reclassification Event”) shall be effected in such a way that holders of Series D Preferred Stock shall be entitled to receive other stock or securities of the Company, then, as a condition of such Reclassification Event, lawful and adequate provisions shall be made whereby the Holder hereof shall thereafter have the right to purchase and receive (in lieu of the shares of Series D Preferred Stock of the Company immediately theretofore purchasable and receivable upon the exercise of the rights represented hereby) such other stock or securities of the Company as may be issued with respect to or in exchange for that number of outstanding shares of such Series D Preferred Stock equal to the number of shares of such stock immediately theretofore purchasable and receivable upon the exercise of the rights represented hereby. In any Reclassification Event, appropriate provision shall be made with respect to the rights and interests of the Holder to the end that the provisions hereof (including, without limitation, provisions for adjustments of the Exercise Price and of the number of Warrant Shares), shall thereafter be applicable, as nearly as may be, in relation to any shares of stock or securities of the Company thereafter deliverable upon the exercise hereof.

3.3. Notice of Adjustment. Upon any adjustment of the Exercise Price or any increase or decrease in the number of Warrant Shares, the Company shall give written notice thereof, by first class mail postage prepaid, addressed to the registered Holder at the address of such Holder as shown on the books of the Company. The notice shall be prepared and signed by the Company’s Chief Financial Officer and shall state the Exercise Price resulting from such adjustment and the increase or decrease, if any, in the number of shares purchasable at such price upon the exercise of this Warrant, setting forth in reasonable detail the method of calculation and the facts upon which such calculation is based.

4. Registrable Securities. Upon exercise of this Warrant, the Warrant Shares shall, on the terms set forth therein, be “Registrable Securities” under that certain Amended and Restated Information and Registration Rights Agreement dated as of June 18, 2008, as it may be amended or restated form time to time (the “Rights Agreement”), to which the Company and certain of its stockholders are parties, and the Holder shall be entitled to all rights granted to the other holders of Registrable Securities thereunder. By its receipt of this Warrant, the Holder agrees, upon exercise of this Warrant, to be bound by the Rights Agreement as an “Investor” thereunder and to execute a counterpart signature page thereto.

5. No Voting or Dividend Rights. Nothing contained in this Warrant shall be construed as conferring upon the holder hereof the right to vote or to consent to receive notice as a stockholder of the Company on any other matters or any rights whatsoever as a stockholder of the Company. No dividends or interest shall be payable or accrued in respect of this Warrant or the interest represented hereby or the shares purchasable hereunder until, and only to the extent that, this Warrant shall have been exercised.

6. Compliance with Securities Act; Transferability of Warrant; Disposition of Warrant Shares and Common Stock.

6.1. Compliance with Securities Act. The Holder, by acceptance hereof, agrees that this Warrant, the Warrant Shares and the shares of Common Stock issuable upon conversion of the Warrant Shares are being acquired for investment and that it shall not offer, sell or otherwise dispose of this Warrant, any Warrant Shares or any shares of Common Stock issuable upon conversion of the Warrant Shares except under circumstances which will not result in a violation of the Act or any applicable state securities laws. This Warrant, the Warrant Shares and the shares of Common Stock issuable upon conversion of the Warrant Shares (unless registered under the Act) shall be stamped or imprinted with a legend in substantially the following form:

“THE SECURITIES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE “ACT”), AND ARE “RESTRICTED SECURITIES” AS DEFINED IN RULE 144 PROMULGATED UNDER THE ACT. THE SECURITIES MAY NOT BE SOLD, OFFERED FOR SALE, TRANSFERRED, PLEDGED, HYPOTHECATED OR OTHERWISE DISTRIBUTED OR DISPOSED OF EXCEPT (I) IN CONJUNCTION WITH AN EFFECTIVE REGISTRATION STATEMENT FOR THE SECURITIES UNDER THE ACT, (II) IN COMPLIANCE WITH RULE 144, OR (III) PURSUANT TO AN OPINION OF COUNSEL, REASONABLY SATISFACTORY TO THE CORPORATION, THAT SUCH REGISTRATION OR COMPLIANCE IS NOT REQUIRED AS TO SAID SALE, OFFER, TRANSFER, PLEDGE, HYPOTHECATION OR OTHER DISTRIBUTION OR DISPOSITION.”

6.2. Accredited Investor; Access to Information; Pre-Existing Relationship. Holder presently qualifies and will as of any exercise of this Warrant qualify as an “accredited investor” within the meaning of Regulation D of the rules and regulations promulgated under the Act. The state or, if Holder does not reside in the United States, the country of residency of Holder (or, in the case of a partnership, corporation or other entity, such entity’s principal place of business) for purposes of the Company’s compliance with applicable securities laws is the state or country listed in Holder’s address as set forth on the signature pages to this Warrant. Holder has had the opportunity to ask questions of, and to receive answers from, appropriate executive officers of the Company with respect to the terms and conditions of the transactions contemplated hereby and with respect to the business, affairs, financial condition and results of operations of the Company. Holder has had access to such financial and other information as is

necessary in order for Holder to make a fully informed decision as to investment in the Company, and has had the opportunity to obtain any additional information necessary to verify any of such information to which Holder has had access. Holder further represents and warrants that the Holder has either (a) a pre-existing relationship with the Company or one or more of its officers or directors consisting of personal or business contacts of a nature and duration which enable the Holder to be aware of the character, business acumen and general business and financial circumstances of the Company or the officer or director with whom such relationship exists or (b) such business or financial expertise as to be able to protect the Holder’s own interests in connection with the purchase of the Warrant Shares.

6.3. Warrant Transferable. Subject to compliance with applicable federal and state securities laws under which this Warrant was purchased, this Warrant and all rights hereunder are transferable, in whole or in part, without charge to the Holder (except for transfer taxes), upon surrender of this Warrant properly endorsed; provided, however, that the Holder shall notify the Company in writing in advance of any proposed transfer and shall not transfer this Warrant or any rights hereunder to any person or entity which is then engaged in a business that in the reasonable judgment of the Company is in direct competition with the Company.

6.4. Disposition of Warrant, Warrant Shares and Common Stock. With respect to any offer, sale, or other disposition of this Warrant, any Warrant Shares, or of any shares of Common Stock issuable upon conversion of the Warrant Shares prior to registration of such shares, the Holder hereof and each subsequent Holder agrees to give written notice to the Company prior thereto, describing briefly the manner thereof, together with a written opinion of such Holder’s counsel, if reasonably requested by the Company, to the effect that such offer, sale or other disposition may be effected without registration or qualification (under the Act as then in effect or any federal or state law then in effect) of such Warrant, Warrant Shares or Common Stock, as the case may be, and indicating whether or not under the Act certificates for such Warrant, Warrant Shares or Common Stock to be sold or otherwise disposed of require any restrictive legend as to applicable restrictions on transferability in order to insure compliance with the Act. Promptly upon receiving such written notice and opinion, the Company, as promptly as practicable, shall notify such Holder that such Holder may sell or otherwise dispose of such Warrant, Warrant Shares or Common Stock, all in accordance with the terms of the notice delivered to the Company. If a determination has been made pursuant to this Section 6.4 that the opinion of the counsel for the Holder is not reasonably satisfactory to the Company, the Company shall so notify the Holder promptly after such determination has been made. Notwithstanding the foregoing, such Warrant, Warrant Shares or Common Stock may be offered, sold or otherwise disposed of in accordance with Rule 144 under the Act, provided that the Company shall have been furnished with such information as the Company may request to provide reasonable assurance that the provisions of Rule 144 have been satisfied. Each certificate representing this Warrant, Warrant Shares or Common Stock thus transferred (except a transfer pursuant to Rule 144) shall bear a legend as to the applicable restrictions on transferability in order to insure compliance with the Act, unless in the aforesaid opinion of counsel for the Holder, such legend is not required in order to insure compliance with the Act. The Company may issue stop transfer instructions to its transfer agent in connection with such restrictions.

6.5. Market Standoff. The Holder agrees that if so requested by the Company or any representative of the underwriters in connection with registration of the initial public offering of any securities of the Company under the Act, the Holder shall not sell or otherwise transfer any Warrant Shares, or any shares of Common Stock issuable upon conversion of the Warrant Shares, or any other securities of the Company during the 180 day period following the effective date of such registration statement. The Company may impose stop transfer instructions with respect to securities subject to the foregoing restrictions until the end of such 180 day period.

7. Modification and Waiver. This Warrant and any provision hereof may be changed, waived, discharged, or terminated only by an instrument in writing signed by the party against which enforcement of the same is sought.

8. Notices. Any notice, request, or other document required or permitted to be given or delivered to the Holder or to the Company hereunder shall be conclusively deemed effectively given upon personal delivery or delivery by courier, or on the first business day after transmission if sent by confirmed facsimile transmission or electronic mail transmission, or five business days after deposit in the United States mail, by registered or certified mail, postage prepaid, addressed (1) if to the Company, as set forth below the Company’s name on the signature pages of this Warrant, and (2) if to the Holder, at the Holder’s address as set forth below the Holder’s name on the signature pages of this Warrant, or at such other address as the Company or the Holder may designate by 10 business days’ advance written notice to the other.

9. Governing Law. This Warrant shall be governed by, and construed in accordance with, the laws of the Commonwealth of Massachusetts, excluding those laws that direct the application of the laws of another jurisdiction.

10. Lost or Stolen Warrant. Upon receipt of evidence reasonably satisfactory to the Company of the loss, theft, destruction, or mutilation of this Warrant and, in the case of any such loss, theft or destruction, upon receipt of an indemnity reasonably satisfactory to the Company, or in the case of any such mutilation, upon surrender and cancellation of such Warrant, the Company, at its expense, will make and deliver a new Warrant, of like tenor, in lieu of the lost, stolen, destroyed or mutilated Warrant.

11. Fractional Shares. No fractional shares shall be issued upon exercise of this Warrant. The Company shall, in lieu of issuing any fractional share, pay the Holder entitled to such fraction a sum in cash equal to such fraction (calculated to the nearest 1/100th of a share) multiplied by the difference between the then effective Exercise Price and the fair market value of one Warrant Share, rounded down to the nearest whole cent; provided, however, that no payment of less than $10.00 shall be required.

12. No Impairment. The Company will not, by charter amendment or by reorganization, transfer of assets, consolidation, merger, dissolution, issue or sale of securities, or any other voluntary action, avoid or seek to avoid the observance or performance of any terms of this Warrant, but will at all times in good faith assist in the carrying out of all such terms and in the taking of all such action as may be necessary or appropriate in order to protect the rights of

the Holder against impairment. Upon the request of the Holder, the Company will at any time during the period this Warrant is outstanding acknowledge in writing, in form satisfactory to Holder, the continued validity of this Warrant and the Company’s obligations hereunder.

13. Successors and Assigns. This Warrant and the rights evidenced hereby shall inure to the benefit of and be binding upon the successors of the Company and the Holder. The provisions of this Warrant are intended to be for the benefit of all Holders from time to time of this Warrant, and shall be enforceable by any such Holder.

INTERCREDITOR AGREEMENT

, 2011

THIS INTERCREDITOR AGREEMENT (this “Agreement”) is among VENTURE LENDING & LEASING V, INC. and VENTURE LENDING & LEASING VI, INC., both Maryland corporations, having their principal places of business at 0000 Xxxxx Xxxxx Xxxxxx, Xxxxx 000, Xxx Xxxx, XX 00000 (each, a “Firm” and together, the “Firms”), MASSACHUSETTS DEVELOPMENT FINANCE AGENCY, a body corporate and politic created under and acting pursuant to authority derived from Chapter 23G of the Massachusetts General Laws, as amended, and having a principal place of business at 000 Xxxxxxx Xxxxxx, Xxxxxx, Xxxxxxxxxxxxx 00000 (the “Lender”), and CONFORMIS, INC., a Delaware corporation having a principal place of business at 00 Xxxxx Xxxxxx, Xxxxxxxxxx, Xxxxxxxxxxxxx 00000 (the “Borrower”).

WHEREAS, the Firms have loaned certain sums to the Borrower (the “Firm Loans”) as evidenced by those certain Loan and Security Agreements dated as of August 11, 2009 and February 16, 2011, respectively, as amended from time to time (the “Firm Agreements”), and various related documents, existing and to be entered into hereafter (together with the Firm Agreements, the “Firm Documents”). Pursuant to the terms of the Firm Documents, the Borrower has granted to each Firm security interests in all the personal property assets, whether now owned or hereafter acquired, of the Borrower (the “Collateral”); and

WHEREAS, the Lender has loaned certain sums to the Borrower (the “MDFA Loan”) as evidenced by that certain Loan Agreement as of the date hereof, as amended from time to time, (the “MDFA Agreement”) and various related documents, existing and to be entered into hereafter (together with the MDFA Agreement, “MDFA Documents”). One of the documents comprising the MDFA Documents is that certain Security Agreement dated as of the date hereof granted by the Borrower in favor of the Lender (the “Security Agreement”) encumbering certain equipment owned by the Borrower and described on Schedule I attached hereto (the “Equipment”); and

WHEREAS, each Firm is willing to consent to the Lender acquiring a senior, first priority security interest in the Equipment; and

WHEREAS, the Lender is willing to consent to each Firm acquiring a subordinate security interest in the Equipment.

NOW, THEREFORE, in consideration of the above, and other valuable consideration, the receipt and sufficiency of which is hereby acknowledged, the parties hereto agree as follows:

1. Each Firm hereby consents to the security interest of the Lender in the Equipment and the parties hereto agree that such Firm’s security interest in the Equipment is subordinate to the security interest of the Lender in the Equipment. The parties agree that: (a) the security

interest of the Lender granted in the Equipment to secure the MDFA Loan shall in all cases be superior to, and entitled to priority over, each Firm’s security interest in the Equipment to secure the Firm Loans; and (b) the security interests of the Firms granted in the other Collateral (excluding the Equipment) to secure the Firm Loans shall in all cases be superior to, and entitled to priority over, the Lender’s security interest, if any, in such other Collateral to secure the MDFA Loan.

2. At all times the Lender may exercise any and all of its rights and remedies under the MDFA Documents with respect to the Equipment only (and no other Collateral). Nothing herein will in any way delay or hinder the Lender’s exercise of its rights and remedies under the MDFA Documents with respect to the Equipment only. Neither Firm may exercise its rights with respect to the Equipment, unless the MDFA Loan has been indefeasibly paid in full or such Firm has received the prior written consent of the Lender. The Lender may not exercise its rights with respect to any Collateral (other than the Equipment), unless the Firm Loans have been indefeasibly paid in full or the Lender has received the prior written consent of the Firms.

3. The Lender may, without the consent of, or notice to, either Firm, (i) grant any indulgence, discharge of indebtedness or release of the Equipment; (ii) alter, amend, cancel, waive or modify any term or condition of the MDFA Loan; and (iii) increase the principal amount of MDFA Loan in accordance with the terms of the Firm Documents. The Firms may, without the consent of, or notice to, the Lender, (i) grant any indulgence, discharge of indebtedness or release of the Collateral (other than the Equipment); (ii) alter, amend, cancel, waive or modify any term or condition of the Firm Loans; and (iii) increase the principal amount of the Firm Loans in accordance with the terms of the MDFA Documents.

4. Each Firm agrees that, upon the occurrence of an Event of Default under and as defined in the MDFA Documents, such Firm shall not object to the Lender taking possession of the Equipment and liquidating the Equipment. The Lender agrees that, upon the occurrence of an Event of Default under and as defined in the Firm Documents, the Lender shall not object to the Firms taking possession of the Collateral (other than the Equipment) and liquidating such Collateral.

5. The Firms and the Lender may each assign its rights under the Firm Documents and the MDFA Documents, as applicable, provided such assignment is made subject to this Agreement.

6. The provisions of this Agreement are solely for the purpose of defining the relative rights of the Firms and the Lender with respect to the Equipment and the other Collateral and, except as specifically provided herein, nothing contained in this Agreement shall be deemed to modify or impair any obligations of the Borrower with respect to the Firm Loans or the MDFA Loan, as applicable.

7. This Agreement may be executed in any number of counterparts, all of which, when taken together, shall constitute one Agreement. Delivery of an executed counterpart of a signature page to this Agreement by facsimile transmission shall be effective as delivery of a manually executed counterpart.

SUBORDINATION AGREEMENT

WHEREAS, ConforMIS, INC., a Delaware corporation having a principal place of business at 00 Xxxxx Xxxxxx, Xxxxxxxxxx, Xxxxxxxxxxxxx 00000 (the “Borrower”) is indebted to those certain creditors listed on Schedule 1 attached hereto (each, a “Creditor”, collectively, the “Creditors”) in the principal amount of $8,000,000; and

WHEREAS, the Borrower has requested MASSACHUSETTS DEVELOPMENT FINANCE AGENCY, a body corporate and politic created under and acting pursuant to authority derived from Chapter 23G of the Massachusetts General Laws, as amended, and having a principal place of business at 000 Xxxxxxx Xxxxxx, Xxxxxx, Xxxxxxxxxxxxx 00000 (the “Lender”) to grant financial accommodations to the Borrower, and the Lender has indicated that it is unwilling to do so unless the Borrower and the Creditors shall join in this Agreement and the Creditors shall subordinate, to the extent and in the manner hereinafter set forth, the indebtedness hereinbefore referred to and also all other indebtedness of the Borrower to the Creditors, direct or indirect, absolute or contingent, due or to become due, now existing or hereafter arising (the “Subordinated Debt”) to all indebtedness of the Borrower to the Lender, direct or indirect, absolute or contingent, due or to become due, now existing or hereafter arising (the “Lender Debt”);

NOW, THEREFORE, in consideration of the premises and as an inducement to the Lender to grant financial accommodations to the Borrower, whether by loan or advance or extension of time for the payment of Lender Debt or otherwise, and in consideration of the granting thereof, the Borrower and the Creditors warrant to and covenant with the Lender as follows:

1. Until all Lender Debt shall have been paid in full, the Borrower shall not, directly or indirectly, make any payment of principal or interest on account of or transfer any collateral for any part of the Subordinated Debt, no Creditor shall demand or accept from Borrower or any other person any such payment or collateral nor cancel, set off or otherwise discharge any part of the Subordinated Debt and neither Borrower nor any Creditor shall otherwise take or permit any action prejudicial to or inconsistent with the Lender’s priority position over the Creditors created by this Agreement.

2. Each Creditor hereby assigns, transfers and sets over to the Lender the Subordinated Debt, as applicable, whether evidenced by negotiable or non-negotiable instruments, securities or other writings, book entries or otherwise, together with any collateral therefor. The indebtedness is recorded on the books of the Borrower.

3. No Creditor will commence or join with any other creditor or creditors of the Borrower in commencing any bankruptcy, reorganization or insolvency proceedings against the Borrower. At any meeting of creditors of the Borrower or in the event of any proceeding, voluntary or involuntary, for the distribution, division or application of all or part of the assets of the Borrower or the proceeds thereof, whether such proceeding be for the liquidation, dissolution or winding up of the Borrower or its business, a receivership, insolvency or bankruptcy proceeding, an assignment for the benefit of creditors or a proceeding by or against the Borrower

for relief under any bankruptcy, reorganization or insolvency law or any law relating to the relief of debtors, readjustment of indebtedness, reorganization, arrangement, composition or extension or otherwise, if all Lender Debt has not been paid in full at the time, the Lender is hereby irrevocably authorized at any such meeting or in any such proceeding:

(a) To enforce claims comprising Subordinated Debt either in its own name or the name or names of any Creditor, by proof of debt, proof of claim, suit or otherwise;

(b) To collect any assets of the Borrower distributed, divided or applied by way of dividend or payment, or any such securities issued, on account of Subordinated Debt and apply the same, or the proceeds of any realization upon the same that the Lender in its discretion elects to effect, to Lender Debt until all Lender Debt shall have been paid in full, rendering any surplus to the Creditors;

(c) To vote claims comprising Subordinated Debt to accept or reject any plan of partial or complete liquidation, reorganization, arrangement, composition or extension; and

(d) To take generally any action in connection with any such meeting or proceeding which the Creditors might otherwise take.

4. Should any payment on account of or any collateral for any part of the Subordinated Debt be received by any of the Creditors, such payment or collateral shall be delivered forthwith to the Lender by the recipient for application to Lender Debt, in the form received except for the addition of any endorsement or assignment necessary to effect transfer of all rights therein to the Lender. The Lender is irrevocably authorized to supply any required endorsement or assignment which may have been omitted. Until so delivered any such payment or collateral shall be held by the recipient in trust for the Lender and shall not be commingled with other funds or property of the recipient.

5. No part of the Subordinated Debt is evidenced by any instrument, security or other writing which has not previously been or is not concurrently being deposited with the Lender; each Creditor is the lawful owner of the Subordinated Debt, as applicable, and no part thereof has been assigned to or subordinated or subjected to any other security interest in favor of anyone other than the Lender. Until all Lender Debt has been paid in full, the Borrower shall not issue any instrument, security or other writing evidencing any part of the Subordinated Debt or amend any existing instrument, security or other writing except at the request of and in the manner requested by the Lender; and no Creditor shall assign or subordinate any part of the Subordinated Debt, as applicable, except to or in favor of the Lender.

6. The Lender is hereby authorized to demand specific performance of this Agreement, whether or not the Borrower shall have complied with the provisions hereof applicable to it, at any time when any of the Creditors shall have failed to comply with any provision hereof applicable to it. Each Creditor hereby irrevocably waives any defense based on the adequacy of a remedy at law which might be asserted as a bar to the remedy of specific performance hereof in any action brought therefor by the Lender. Each Creditor further waives presentment, notice and protest in connection with all negotiable instruments evidencing Lender

Debt or Subordinated Debt to which it may be a party, notice of the acceptance of this Agreement by the Lender, notice of any loan made, extension granted or other action taken in reliance hereon and all demands and notices of every kind in connection with this Agreement, Lender Debt or Subordinated Debt; assent to any renewal, extension or postponement of the time of payment of Lender Debt or any other indulgence with respect thereto, to any substitution, exchange or release of collateral therefor and to the addition or release of any person primarily or secondarily liable thereon; and agree to the provisions of any instrument, security or other writing evidencing Lender Debt.

7. The Borrower and the Creditors shall execute and deliver to the Lender such further instruments and shall take such further action as the Lender may at any time or times reasonably request in order to carry out the provisions and intent of this Agreement.

8. Upon (i) the irrevocable payment in full of all indebtedness of the Borrower to the Lender, and (ii) the termination of all agreements under which the Lender is obligated to extend credit, to make advances, loans or other financial accommodations to the Borrower, the Creditors (acting unanimously), by written notice to the Lender, terminate this Agreement. If all indebtedness of the Borrower to the Lender is at any time or times hereafter paid in full and thereafter the Borrower again becomes indebted to the Lender, the provisions of this Agreement shall apply to such new indebtedness unless, before the same is incurred the Creditors notify the Lender in writing to the contrary. If, in reliance upon this Agreement, the Lender grants loans or extensions or takes other action, after the termination of this Agreement by the Creditors, but prior to the receipt by the Lender of written notice of such termination, the Lender’s rights shall be the same as they would have been had such termination not occurred, and the Borrower and the Creditors shall indemnify the Lender and save it harmless from and against any loss, cost, liability or expense which it may have incurred or suffered by reason of any action so taken by it.

9. If any warranty herein contained shall prove to have been materially false when made or in the event of a breach by the Borrower or the Creditors in the performance of any of the terms hereof, the Lender may, at its option, declare all Lender Debt to be forthwith due and payable, without presentment, demand, protest, or notice of any kind, notwithstanding any time or credit otherwise allowed.

10. The rights granted to the Lender hereunder are solely for its protection and nothing herein contained shall impose on the Lender any duties with respect to any property of the Borrower or the Creditors received hereunder beyond reasonable care in its custody and preservation while in the Lender’s possession. The Lender shall have no duty to preserve rights against prior parties in any instrument or chattel paper received hereunder.

11. This Agreement is intended to take effect as a sealed instrument, shall be binding upon the Borrower, the Creditors, their respective executors, administrators, other legal representatives, successors and assigns, shall inure to the benefit of the Lender, its successors and assigns and shall be construed in accordance with the laws of the Commonwealth of Massachusetts.
