REPRESENTATIONS AND WARRANTIES OF THE COMPANY

As a material inducement to each Purchaser to enter into this Agreement, and subject to the exceptions set forth in the Company SEC Documents (as defined below) filed prior to the date of this Agreement, the Company hereby represents and warrants to each Purchaser that:

3.1 Organization of the Company. Each of the Company and its Subsidiaries is a legal entity duly organized, validly existing and in good standing under the laws of its jurisdiction of organization. The Company has full corporate power and authority to own, lease and operate its properties, to conduct its business as described in the Company SEC Documents and to enter into and perform its obligations under the Transaction Documents. The Company is duly qualified to transact business and is in good standing or equivalent status in each other jurisdiction in which such qualification is required, whether by reason of the ownership or leasing of property or the conduct of business, except where the failure so to qualify or to be in good standing would not, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect.

3.2 Authorization; Enforcement.

(a) The Company has all requisite corporate power and authority to enter into and to perform its obligations under this Agreement and the other Transaction Documents, to consummate the transactions contemplated hereby and thereby, to issue the Securities in accordance with the terms hereof and otherwise to carry out its obligations hereunder and thereunder. The execution, delivery and performance of this Agreement by the Company and the consummation by it of the transactions contemplated thereby (including the issuance of the Securities, Note Shares and Warrant Shares) have been duly authorized by the Board and no

further action, consent or authorization is required by the Company, its officers, directors or shareholders in connection therewith. This Agreement has been duly executed by the Company and constitutes the legal, valid and binding obligation of the Company enforceable against the Company in accordance with its terms, except as enforceability may be limited by applicable bankruptcy, insolvency, reorganization or moratorium or similar laws affecting creditors’ and contracting parties’ rights generally and except as enforceability may be subject to general principles of equity and except as rights to indemnity and contribution may be limited by state or federal securities laws or public policy underlying such laws (collectively, the “Enforceability Exceptions.”)

(b) The Notes have been duly and validly authorized and, when issued, will be in the form contemplated by the Indenture. The Notes, when executed by the Company and authenticated by the Trustee in accordance with the provisions of the Indenture and when delivered to and paid for by the Purchasers in accordance with the terms of this Agreement, will constitute valid and legally binding obligations of the Company, will be enforceable against the Company in accordance with their terms, subject to the Enforceability Exceptions, and will be entitled to the benefits of the Indenture free and clear of any Encumbrance and will conform to the description thereof in the Indenture.

(c) The Indenture, Escrow Agreement and Warrants have been duly and validly authorized by the Company and, when executed and delivered by the Company (assuming, with respect to the Indenture and the Escrow Agreement, the due authorization, execution and delivery by the Trustee or Escrow Agent, as applicable), will constitute valid and legally binding obligations of the Company, enforceable against the Company in accordance with their terms, except that the enforcement thereof may be subject to the Enforceability Exceptions.

3.3 Capitalization. The authorized capital stock of the Company, as of the date hereof, consisted of 25,045,765 shares of Company Common Stock, of which 14,927,351 shares were issued and outstanding, and 5,000,000 shares of preferred stock, none of which were issued and outstanding. All of the issued and outstanding shares of Company Common Stock have been duly authorized, validly issued, fully paid, and non-assessable. Except as disclosed in the Governance Agreement with Grifols, S.A. attached as Exhibit 10.23 to the Company’s 10-K report filed March 30, 2016 (the “Governance Agreement”) and in the Company SEC Documents, the Company does not have outstanding any options to purchase, or any preemptive rights or other rights to subscribe for or to purchase, any securities or obligations convertible into, or any contracts or commitments to issue or sell, shares of its capital stock or any such options, rights, convertible securities or obligations other than options and restricted stock units granted under the Company’s stock option plans. There are no bonds, debentures, notes or other Indebtedness having general voting rights (or convertible into securities having such rights) of the Company issued and outstanding. The issuance and sale of the Notes and Warrants will not obligate the Company to issue shares of Company Common Stock or other securities to any

Person (other than the Purchasers or any permitted transferees) and will not result in a right of any holder of Company securities to adjust the exercise, conversion, exchange or reset price under any of such securities. There are no shareholders agreements, voting agreements or other similar agreements with respect to the Company’s capital stock to which the Company is a party or, to the Company’s knowledge, between or among any of the Company’s shareholders except as disclosed in the Company SEC documents.

3.4 Issuance of Securities. The Warrants have been duly and validly authorized and, when executed, issued and delivered by the Company pursuant to this Agreement, will constitute legal, valid and binding obligations of the Company, enforceable in accordance with their terms. The shares of Company Common Stock issuable upon conversion of the Notes in accordance with the Indenture (the “Note Shares”) and the shares of Company Common Stock issuable upon exercise of the Warrants (the “Warrant Shares”) have been duly authorized and validly reserved for issuance pursuant to the terms of the Notes and Warrants and, upon conversion of the Notes and exercise of the Warrants in accordance with their terms, the Note Shares and Warrant Shares issuable thereupon will be validly issued, fully paid and non-assessable and will not be subject to preemptive rights or other similar rights of shareholders of the Company or any of its Subsidiaries and will be free of any voting or transfer restrictions pursuant to the Company’s Charter Documents or any agreement or other instrument to which the Company or any of its Subsidiaries is a party that have not been validly waived (other than as provided in this Agreement). The certificates of such Note Shares or Warrant Shares will be in due and proper form. The issuance of the Securities, the Note Shares and the Warrant Shares is not subject to any preemptive or similar rights that have not been waived.

3.5 No Conflicts; Government Consents and Permits.

REGISTRATION RIGHTS

7.1 Mandatory Registration. The Company shall prepare and file as soon as reasonably practicable, but in no event later than thirty (30) days after the date hereof (such filing date, the “Mandatory Shelf Filing Date”), a registration statement under the Securities Act to

permit the public resale of all of the Registrable Securities (the registration statement on such form, as amended or supplemented, the “Registration Statement”). The Registration Statement filed pursuant to this Section 7.1 shall be on such appropriate registration form of the SEC as shall be selected by the Company so long as it permits the continuous offering of the Registrable Securities pursuant to Rule 415 (or any similar provision then in effect) under the Securities Act at then prevailing market prices. The Company shall use its commercially reasonable efforts to cause the Registration Statement to be declared effective under the Securities Act by the Commission within ninety (90) calendar days after the Closing. The Registration Statement shall provide, in the plan of distribution section, for the resale pursuant to any method or combination of methods legally available to, and requested by, the Holders of any and all Registrable Securities covered by the Registration Statement. The Company shall use its commercially reasonable efforts to keep the Registration Statement continuously effective under the Securities Act until the earlier of (a) the date when all of the Registrable Securities covered by such Registration Statement have been sold and (b) the date on which all of the Registrable Securities become eligible for resale without restriction and without the need for current public information pursuant to any section of Rule 144 (or any similar provision then in effect) under the Securities Act (such period, the “Effectiveness Period”). The Registration Statement, when effective (including the documents incorporated therein by reference), will comply as to form in all material respects with all applicable requirements of the Securities Act and the Exchange Act and will not contain an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading (in the case of any prospectus contained in such Registration Statement, in the light of the circumstances under which a statement is made). As soon as practicable following the date that the Registration Statement becomes effective, but in any event within one (1) Business Day of such date, the Company shall notify the Holders of the effectiveness of the Registration Statement and, if requested by any such Holder, confirm such notice in writing.

7.2 Failure to File or Become Effective; Liquidated Damages.

(a) Each holder of Registrable Securities shall be entitled to a payment (with respect to the Registrable Securities of each such holder), as liquidated damages and not as a penalty, of 2.0% of the Aggregate Purchase Price for the Securities purchased by such Purchaser hereunder per 30-day period (accruing on a daily basis) that any Registration Default (as defined below) continues (such damages collectively, the “Liquidated Damages”), if any of the following events occur (each such event in clauses (i) through (iii) below being herein called a “Registration Default”):

(i) the Registration Statement has not been filed by the Mandatory Shelf Filing Date;

(ii) the Registration Statement has not been declared effective by the SEC on or before the date that is ninety (90) calendar days following the Closing Date (the “Effectiveness Deadline”); or

(iii) the Registration Statement is declared effective by the Commission but (A) the Registration Statement thereafter ceases to be effective during the Effectiveness Period or (B) as specified in Section 7.3(b), the Registration Statement ceases to be usable in connection with resales of Registrable Securities during the periods specified herein and the Company fails to (1) cure the Registration Statement within five (5) Business Days by a post-effective amendment or a report filed pursuant to the Exchange Act or (2) if applicable, terminate the suspension period described in Section 7.3(b) by the 30th day, as applicable.

Each of the foregoing will constitute a Registration Default whatever the reason for any such event and whether it is voluntary or involuntary or is beyond the Company’s control or pursuant to operation of law or as a result of any action or inaction by the Commission.

(b) Liquidated Damages shall be paid in accordance with Section 7.2(d) below. Other than the obligation of payment of any Liquidated Damages in accordance with the terms hereof, the Company will have no other liabilities for monetary damages with respect to its registration obligations. With respect to each Holder, the Company’s obligations to pay Liquidated Damages remain in effect only so long as the Registrable Securities held by the holder are not eligible for resale without restriction and without the need for current public information pursuant to any section of Rule 144 (or any similar provision then in effect) under the Securities Act; provided however, any obligations of the Company for accrued but unpaid Liquidated Damages at the time such Registrable Securities become eligible for resale without restriction and without the need for current public information pursuant to any section of Rule 144 (or any similar provision then in effect) under the Securities Act shall survive until such time as all such obligations with respect to such Registrable Securities shall have been satisfied in full. Notwithstanding anything to the contrary contained herein, in no event shall the Liquidated Damages payable to any Purchaser by the Company hereunder exceed an aggregate amount that exceeds five percent (5.0)% of the Aggregate Purchase Price paid by such Purchaser for such Purchaser’s Securities.

(c) A Registration Default referred to in clauses (a)(i) or (a)(ii) shall be deemed not to have occurred and be continuing, and no Liquidated Damages shall accrue as a result thereof, in relation to the Registration Statement or the related prospectus if (i) (A) such Registration Default has occurred solely as a result of material events with respect to the Company that would need to be described in such Registration Statement or the related prospectus, or (B) the Registration Default relates to any information supplied or failed to be supplied by a holder of Securities and (ii) the Company is proceeding promptly and in good faith to amend or supplement the Registration Statement and related prospectus to describe such events as required by Section 7.3; provided, however, that in any case if such Registration

Default occurs for a continuous period in excess of forty-five (45) days beyond any permitted suspension period (as provided by Section 7.3), Liquidated Damages shall be payable in accordance with the above paragraph (b) from the day such Registration Default occurs until such Registration Default is cured.

(d) Any amounts of Liquidated Damages pursuant to Section 7.2(a) will be payable in cash in arrears on each Liquidated Damages Payment Date. The amount of Liquidated Damages will be determined on the basis of a 360-day year comprised of twelve (12) 30-day months, and the actual number of days on which Liquidated Damages accrued during such period.

7.3 Blackout and Delay Rights. Notwithstanding anything to the contrary contained herein:

(a) the Company shall not be required to file a Registration Statement (or any amendment thereto) or, if a Registration Statement has been filed but not declared effective by the Commission, request effectiveness of such Registration Statement, for a period of up to forty-five (45) days, if (i) the Company determines in good faith that a postponement is in the best interest of the Company and its Shareholders generally due to a pending transaction involving the Company (including a pending securities offering by the Company, or any proposed financing, acquisition, merger, tender offer, business combination, corporate reorganization, consolidation or other significant transaction involving the Company), (ii) the Company determines such registration would render the Company unable to comply with applicable securities laws, (iii) the Company determines such registration would require disclosure of material information that the Company has a bona fide business purpose for preserving as confidential or (iv) audited financial statements as of a date other than the fiscal year end of the Company would be required to be prepared; provided, however, that in no event shall any such period exceed an aggregate of ninety (90) days in any 365-day period; and

(b) the Company may, upon written notice to any holder whose Registrable Securities are included in the Registration Statement or other registration statement contemplated by this Agreement, suspend such holder’s use of any prospectus which is a part of the Registration Statement or other registration statement (in which event the holder shall discontinue sales of the Registrable Securities pursuant to the Registration Statement or other registration statement contemplated by this Agreement but may settle any previously made sales of Registrable Securities) if (i) the Company determines that it would be required to make disclosure of material information in the Registration Statement that the Company has a bona fide business purpose for preserving as confidential or (ii) the Company has experienced some other material non-public event the disclosure of which at such time, in the good faith judgment of the Company, would adversely affect the Company; provided, however, in no event shall the holders be suspended from selling Registrable Securities pursuant to the Registration Statement or other registration statement for a period that exceeds an aggregate of sixty (60) days in any

180-day period or ninety (90) days in any 365-day period. Upon disclosure of such information or the termination of the condition described above, the Company shall provide prompt notice to the holders whose Registrable Securities are included in the Registration Statement, and shall promptly terminate any suspension of sales it has put into effect and shall take such other reasonable actions to permit registered sales of Registrable Securities as contemplated in this Agreement.

7.4 Sale Procedures. In connection with its obligations under this Article VII the Company will:

(a) prepare and file with the SEC such amendments and supplements to the Registration Statement and the prospectus used in connection therewith as may be necessary to keep the Registration Statement effective for the Effectiveness Period and as may be necessary to comply with the provisions of the Securities Act with respect to the disposition of all Registrable Securities covered by the Registration Statement;

(b) make available to each Purchaser of Registrable Securities (i) as far in advance as reasonably practicable before filing the Registration Statement or any other registration statement contemplated by this Agreement or any supplement or amendment thereto, upon written request, copies of reasonably complete drafts of all such documents proposed to be filed (including exhibits and each document incorporated by reference therein to the extent then required by the rules and regulations of the SEC), and provide each such Purchaser the opportunity to object to any information pertaining to such Purchaser and its plan of distribution that is contained therein and make the corrections reasonably requested by such Purchaser with respect to such information prior to filing the Registration Statement or such other registration statement or supplement or amendment thereto and (ii) such number of copies of the Registration Statement or such other registration statement and the prospectus included therein and any supplements and amendments thereto as such Purchaser may reasonably request in order to facilitate the public sale or other disposition of the Registrable Securities covered by such Registration Statement or other registration statement;

(c) if applicable, use its commercially reasonable efforts to register or qualify the Registrable Securities covered by the Registration Statement or any other registration statement contemplated by this Agreement under the securities or blue sky laws of such jurisdictions as any Purchaser shall reasonably request in writing by the time the Registration Statement is declared effective by the SEC; provided, however, that the Company will not be required to qualify generally to transact business in any jurisdiction where it is not then required to so qualify or to take any action that would subject it to general service of process in any such jurisdiction where it is not then so subject;

(d) promptly notify each Purchaser, and, if requested by any such Purchaser, confirm such advice in writing, at any time when a prospectus relating thereto is required to be delivered by any of them under the Securities Act, of (i) the filing of the Registration Statement or any other registration statement contemplated by this Agreement or any prospectus or prospectus supplement to be used in connection therewith, or any amendment or supplement thereto, and, with respect to such Registration Statement or any other registration statement or any post-effective amendment thereto, when the same has become effective; and (ii) the receipt of any written comments from the SEC with respect to any filing referred to in clause (i) and any written request by the SEC for amendments or supplements to the Registration Statement or any other registration statement or any prospectus or prospectus supplement thereto;

(e) promptly notify each Purchaser, and, if requested by any such Purchaser, confirm such advice in writing, at any time when a prospectus relating thereto is required to be delivered under the Securities Act, of (i) the happening of any event as a result of which the prospectus or prospectus supplement contained in the Registration Statement or any other registration statement contemplated by this Agreement, as then in effect, includes an untrue statement of a material fact or omits to state any material fact required to be stated therein or necessary to make the statements therein not misleading (in the case of any prospectus contained therein, in the light of the circumstances under which a statement is made), (ii) the issuance or express threat of issuance by the SEC of any stop order suspending the effectiveness of the Registration Statement or any other registration statement contemplated by this Agreement, or the initiation of any proceedings for that purpose, or (iii) the receipt by the Company of any notification with respect to the suspension of the qualification of any Registrable Securities for sale under the applicable securities or blue sky laws of any jurisdiction. Following the occurrence of any of the events set forth in clauses (i) through (iii) above, the Company agrees to as promptly as practicable amend or supplement the prospectus or prospectus supplement or take other appropriate action so that the prospectus or prospectus supplement does not include an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading in the light of the circumstances then existing and to take such other commercially reasonable action as is necessary to remove a stop order, suspension, threat thereof or proceedings related thereto;

(f) upon written request and subject to appropriate confidentiality obligations, furnish to each Purchaser copies of any and all transmittal letters or other correspondence with the SEC or any other governmental agency or self-regulatory body or other body having jurisdiction (including any domestic or foreign securities exchange) relating to the Registration Statement;

(g) otherwise use its commercially reasonable efforts to comply with all applicable rules and regulations of the SEC;

(h) use its commercially reasonable efforts to cause the Registrable Securities to be registered with or approved by such other governmental agencies or authorities as may be necessary by virtue of the business and operations of the Company to enable the holders of the Registrable Securities to consummate the disposition of such Registrable Securities;

(i) if requested by a Purchaser, (i) incorporate in a prospectus supplement or post-effective amendment such information as such Purchaser reasonably requests to be included therein relating to the sale and distribution of Registrable Securities, including information with respect to the number of Registrable Securities being offered or sold, the purchase price being paid therefor and any other terms of the offering of the Registrable Securities to be sold in such offering and (ii) make all required filings of such prospectus supplement or post-effective amendment after being notified of the matters to be incorporated in such prospectus supplement or post-effective amendment.

The Company will not name a holder of the Registrable Securities as an underwriter as defined in Section 2(a)(11) of the Securities Act in any Registration Statement without such holder’s consent. If the staff of the SEC requires the Company to name any holder of the Registrable Securities as an underwriter as defined in Section 2(a)(11) of the Securities Act, and such holder does not consent thereto, then such holder’s Registrable Securities shall not be included on the Registration Statement and the Company shall have no further obligations hereunder with respect to Registrable Securities held by such holder.

Each holder of Registrable Securities, upon receipt of notice from the Company of the happening of any event of the kind described in Section 7.4(e), shall forthwith discontinue offers and sales of the Registrable Securities by means of a prospectus or prospectus supplement until such holder’s receipt of the copies of the supplemented or amended prospectus contemplated by Section 7.4(e) or until it is advised in writing by the Company that the use of the prospectus may be resumed and has received copies of any additional or supplemental filings incorporated by reference in the prospectus, and, if so directed by the Company, such holder will deliver to the Company (at the Company’s expense) all copies in their possession or control, other than permanent file copies then in such holder’s possession, of the prospectus covering such Registrable Securities current at the time of receipt of such notice.

7.5 Cooperation by Holders. The Company shall have no obligation to include Registrable Securities of a holder in the Registration Statement who has failed to timely furnish such information that the Company determines, after consultation with its counsel, is reasonably required in order for the registration statement or prospectus supplement, as applicable, to comply with the Securities Act.

7.6 Expenses.

(a) The Company will pay all reasonable Registration Expenses (as defined below) as determined in good faith. In addition, except as otherwise provided in Section 7.7 hereof, the Company shall not be responsible for any separate legal fees incurred by holders in connection with the exercise of such holders’ rights hereunder.

(b) “Registration Expenses” means, subject to the second sentence of Section 7.6(a) above, all expenses incident to the Company’s performance under or compliance with this Agreement to effect the registration of Registrable Securities on the Registration Statement pursuant to Section 7.1, and the disposition of such Registrable Securities, including, without limitation, all registration, filing, qualification and other fees and expenses of complying with securities or blue sky laws, fees of FINRA, fees of trustees, all word processing, duplicating and printing expenses, any transfer taxes and the fees and disbursements of counsel and independent public accountants for the Company, including the expenses of any special audits or “cold comfort” letters required by or incident to such performance and compliance.

7.7 Indemnification.

(a) Indemnification by the Company. In the event of any registration of any Registrable Securities of the Company under the Securities Act pursuant to this Agreement, the Company will, and hereby does, indemnify and hold harmless the seller of any Registrable Securities covered by such registration statement, its directors and officers, each other Person who participates in the offering or sale of such securities and each other Person, if any, who controls such seller, within the meaning of the Securities Act, against any losses, claims, damages or liabilities, joint or several, to which such seller or any such director or officer or controlling person may become subject, under the Securities Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions or proceedings, whether commenced or threatened, in respect thereof) arise out of or are based upon any untrue statement or alleged untrue statement of any material fact contained in any registration statement under which such securities were registered under the Securities Act, any preliminary prospectus, final prospectus or summary prospectus contained therein, or any amendment or supplement thereto, or any omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, and the Company will reimburse such seller and each such director, officer and controlling person for any legal or any other expenses reasonably incurred by them in connection with investigating or defending any such loss, claim, liability, action or proceeding; provided that the Company shall not be liable in any such case to the extent that any such loss, claim, damage, liability (or action or proceeding in respect thereof) or expense arises out of or is based upon an untrue statement or alleged untrue statement or omission or alleged omission made in such registration statement, any such preliminary prospectus, final prospectus, summary prospectus, amendment or supplement in reliance upon and in conformity with information furnished to the Company in writing or electronically by such seller stating that it is for use in the preparation thereof. Such indemnity shall remain in full force and effect regardless of any investigation made by or on behalf of such seller or any such director, officer or controlling person and shall survive the transfer of such securities by such seller.

(b) Indemnification by the Sellers. The Company may require, as a condition to including any Registrable Securities in any registration statement filed pursuant to Section 7.1 above, that the Company shall have received an undertaking reasonably satisfactory to it from the prospective seller of such securities, to, severally and not jointly, indemnify and hold harmless (in the same manner and to the same extent as set forth in Section 7.7(a) above) the Company, each director of the Company, each officer of the Company and each other Person, if any, who controls the Company within the meaning of the Securities Act, with respect to any statement or alleged statement in or omission or alleged omission from such registration statement, any preliminary prospectus, final prospectus or summary prospectus contained therein, or any amendment or supplement thereto, if such statement or alleged statement or omission or alleged omission was made in reliance upon and in conformity with information furnished to the Company in writing or electronically by such seller stating that it is for use in the preparation of such registration statement, preliminary prospectus, final prospectus, summary prospectus, amendment or supplement. The maximum liability of each seller for any such indemnification shall not exceed the amount of proceeds received by such seller from the sale of his/its Registrable Securities. Such indemnity shall remain in full force and effect, regardless of any investigation made by or on behalf of the Company or any such director, officer or controlling Person and shall survive the transfer of such securities by such seller.

(c) Notices of Claims, etc. Promptly after receipt by an indemnified party of notice of the commencement of any action or proceeding involving a claim referred to in Sections 7.7(a) or 7.7(b) above, such indemnified party will, if a claim in respect thereof is to be made against an indemnifying party, give written notice to the latter of the commencement of such action; provided that the failure of any indemnified party to give notice as provided herein shall not relieve the indemnifying party of its obligations under Sections 7.7(a) or 7.7(b) above, except to the extent that the indemnifying party is materially prejudiced by such failure to give notice. In case any such action is brought against an indemnified party, unless in such indemnified party’s reasonable judgment a conflict of interest between such indemnified and indemnifying parties may exist in respect of such claim, the indemnifying party shall be entitled to participate in and to assume the defense thereof, jointly with any other indemnifying party similarly notified to the extent that it may wish, with counsel reasonably satisfactory to such indemnified party, and after notice from the indemnifying party to such indemnified party of its election so to assume the defense thereof, the indemnifying party shall not be liable to such indemnified party for any legal or other expenses subsequently incurred by the latter in connection with the defense thereof other than reasonable costs of investigation. No indemnifying party shall, without the consent of the indemnified party, consent to entry of any judgment or enter into any settlement unless such judgment or settlement imposes no liability or obligation on the indemnified party, and does not include any admission of culpability or wrongdoing on the part of the indemnified party, and includes a complete and unconditional release from all liability of, the indemnified party in respect of the applicable claim or litigation.

(d) Other Indemnification. Indemnification similar to that specified in Sections 7.7(a), 7.7(b) and 7.7(c) above (with appropriate modifications) shall be given by the Company and each seller of Registrable Securities with respect to any required registration or other qualification of securities under any Federal or state law or regulation of any governmental authority other than the Securities Act.

(e) Indemnification Payments. The indemnification required by this Section 7.7 shall be made by periodic payments of the amount thereof during the course of the investigation or defense, as and when bills are received or expense, loss, damage or liability is incurred.

7.8 Rule 144 Reporting. With a view to making available the benefits of certain rules and regulations of the SEC that may permit the sale of the Registrable Securities to the public without registration, the Company agrees to use its commercially reasonable efforts to:

(a) make and keep public information regarding the Company available, as those terms are understood and defined in Rule 144 under the Securities Act, at all times from and after the date hereof;

(b) file with the SEC in a timely manner all reports and other documents required of the Company under the Securities Act and the Exchange Act at all times from and after the date hereof; and

(c) so long as a Purchaser owns any Registrable Securities, furnish, (i) to the extent accurate, forthwith upon request, a written statement by the Company that it has complied with the reporting requirements of Rule 144 under the Securities Act and (ii) unless otherwise available via ▇▇▇▇▇, to such Purchaser forthwith upon written request a copy of the most recent annual or quarterly report of the Company, and such other reports and documents so filed as such Purchaser may reasonably request in writing in availing itself of any rule or regulation of the SEC allowing such Purchaser to sell any such securities without registration.

7.9 Transfer or Assignment of Registration Rights. The rights to cause the Company to register Registrable Securities granted to the Purchasers by the Company under this Article VII may be transferred or assigned by any Purchaser to one or more transferees or assignees of Registrable Securities; provided, however, that (a) unless the transferee or assignee is an Affiliate of, and after such transfer or assignment continues to be an Affiliate of, such Purchaser, the amount of Registrable Securities transferred or assigned to such transferee or assignee shall represent at least $500,000 of Registrable Securities (based on the Aggregate Purchase Price of the Notes and Warrants transferred or assigned to such Person and the market price of the Note Shares and Warrant shares at the time of transfer), (b) the Company is given written notice prior to any said transfer or assignment, stating the name and address of each such transferee or assignee and identifying the Registrable Securities with respect to which such registration rights are being transferred or assigned, and (c) each such transferee or assignee assumes in writing responsibility for its portion of the obligations of such Purchaser under this Agreement.

7.10 Specific Performance. Damages in the event of breach of this Article VII of this Agreement by a party hereto may be difficult, if not impossible, to ascertain, and it is therefore agreed that, upon the occurrence of such a breach, each such Person, in addition to and without limiting any other remedy or right it may have, will have the right to an injunction or other equitable relief in any court of competent jurisdiction, enjoining any such breach, and enforcing specifically the terms and provisions of this Article VII, and each of the parties hereto hereby waives any and all defenses it may have on the ground of lack of jurisdiction or competence of the court to grant such an injunction or other equitable relief. The existence of this right will not preclude any such Person from pursuing any other rights and remedies at law or in equity that such Person may have.

FORM OF WARRANT

ARADIGM CORPORATION

WARRANT TO PURCHASE COMMON STOCK

Warrant No.:

Date of Issuance: , 2016 (“Issuance Date”)

Aradigm Corporation, a California corporation (the “Company”), hereby certifies that, for good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, , the registered holder hereof or its permitted assigns (the “Holder”), is entitled, subject to the terms set forth below, upon exercise of this warrant to purchase from the Company, at the Exercise Price (as defined below) then in effect, [ ] fully paid and nonassessable shares of Common Stock (as defined below) (subject to adjustment as provided herein) of the Company (the “Warrant” and such shares of Common Stock, the “Warrant Shares”), at any time or times commencing on the later of (a) 180 days after the Issuance Date and (b) the Public Release Date (as defined below) (such periods, the “Exercise Periods”). Except as otherwise defined herein, capitalized terms in this Warrant shall have the meanings set forth in Section 13. This Warrant is one of the Warrants issued pursuant to Article II of the Securities Purchase Agreement (“SPA Warrants”), dated as of April 21, 2016, by and among the Company and the purchasers named on Schedules A and B therein (the “Securities Purchase Agreement”).

1. Exercise of Warrant.

(a) Mechanics of Exercise. Subject to the terms and conditions hereof, this Warrant may be exercised by the Holder during the Exercise Periods, in whole or in part, by delivery (whether via facsimile or otherwise) of a written notice, in the form attached hereto as Exhibit A (the “Exercise Notice”), of the Holder’s election to exercise this Warrant. Within one (1) Trading Day following an exercise of this Warrant as aforesaid, the Holder shall deliver payment to the Company of an amount equal to the Exercise Price in effect on the date of such exercise multiplied by the number of Warrant Shares as to which this Warrant was so exercised (the “Aggregate Exercise Price”) in cash or via wire transfer of immediately available funds.

The Holder shall not be required to deliver the original of this Warrant in order to effect an exercise hereunder. Execution and delivery of an Exercise Notice with respect to less than all of the Warrant Shares shall have the same effect as cancellation of the original of this Warrant and issuance of a new Warrant evidencing the right to purchase the remaining number of Warrant Shares. Execution and delivery of an Exercise Notice for all of the then-remaining Warrant Shares shall have the same effect as cancellation of the original of this Warrant after delivery of the Warrant Shares in accordance with the terms hereof. Upon the exercise of the rights represented by this Warrant, the Warrant Shares shall be issued and registered in the name of the Holder or persons affiliated with the Holder, if the Holder so designates, within a reasonable time after the rights represented by this Warrant shall have been so exercised. The Warrant Shares shall be issued in certificate form if so requested. The Holder acknowledges and agrees that this Warrant cannot be exercised unless, to the extent a notification under the ▇▇▇▇-▇▇▇▇▇-▇▇▇▇▇▇ Antitrust Improvements Act of 1976, as amended (the “HSR Act’) is required, all applicable waiting periods under the HSR Act shall have expired or been terminated and any applicable approvals, consents, or authorizations under any applicable merger control, competition, antitrust or foreign investment laws (collectively, “Approvals”) shall have been obtained, and to the extent applicable, the Company and the Holder will file with the proper authorities all forms and other documents necessary to be filed pursuant to the HSR Act, and the regulations promulgated thereunder, as promptly as possible and shall cooperate with each other in promptly producing such additional information as those authorities may reasonably require to allow expiration or early termination of the waiting period provided by the HSR Act or as otherwise necessary to comply with statutory requirements of the Federal Trade Commission or the Department of Justice.

(b) Exercise Price. For purposes of this Warrant, “Exercise Price” means $5.21 per share of Common Stock, subject to adjustment as provided herein.

(c) Insufficient Authorized Shares. From and after the Issuance Date, the Company shall at all times keep reserved for issuance under this Warrant a number of shares of Common Stock as shall be necessary to satisfy the Company’s obligation to issue shares of Common Stock hereunder (without regard to any limitation otherwise contained herein with respect to the number of shares of Common Stock that may be acquirable upon exercise of this Warrant).

(d) Exercise Limitation. Notwithstanding any other provision herein and except for First Eagle Investment Management, LLC and any of its Affiliates, the Holder may not exercise the Warrant to the extent that immediately following such exercise Holder (together with its Affiliates and any other Persons whose beneficial ownership of shares of Common Stock would be aggregated with the Holder’s for purposes of Section 13(d) of the ▇▇▇▇ ▇▇▇) would beneficially own more than 19.99% (the “Maximum Percentage”) of the number of outstanding shares of Common Stock. For purposes of the foregoing sentence, the aggregate number of shares of Common Stock beneficially owned by such Holder, its Affiliates and any other Persons whose beneficial ownership of shares of Common Stock would be aggregated with the Holder’s for purposes of Section 13(d) of the 1934 Act shall include the number of shares of Common Stock issuable upon exercise of this Warrant with respect to which the determination of such sentence is being made, but shall exclude shares of Common Stock which would be issuable

upon (i) exercise of the remaining, unexercised portion of this Warrant beneficially owned by such Holder and its Affiliates and any other Persons whose beneficial ownership of shares of Common Stock would be aggregated with the Holder’s for purposes of Section 13(d) of the 1934 Act, and (ii) exercise or conversion of the unexercised or unconverted portion of any other securities of the Company beneficially owned by such Holder and its Affiliates and any other Persons whose beneficial ownership of shares of Common Stock would be aggregated with the Holder’s for purposes of Section 13(d) of the 1934 Act (including, without limitation, any convertible notes or convertible preferred stock or warrants) subject to a limitation on conversion or exercise analogous to the limitation contained herein. Except as set forth in the preceding sentence, for purposes of this paragraph, beneficial ownership shall be calculated in accordance with Section 13(d) of the 1934 Act. For purposes of this Warrant, in determining the number of outstanding shares of Common Stock, the Holder may rely on the number of outstanding shares of Common Stock as reflected in (1) the Company’s most recent Form 10-K, Form 10-Q, Current Report on Form 8-K or other public filing with the Securities and Exchange Commission, as the case may be, (2) a more recent public announcement by the Company or (3) any other notice by the Company or the Transfer Agent setting forth the number of shares of Common Stock outstanding. In any case, the number of outstanding shares of Common Stock shall be determined after giving effect to the conversion or exercise of securities of the Company, including the Warrants, by the Holder and its Affiliates since the date as of which such number of outstanding shares of Common Stock was reported. The provisions of this paragraph shall be construed and implemented in a manner other than in strict conformity with the terms of this Section 1(d) to correct this paragraph (or any portion hereof) which may be defective or inconsistent with the intended beneficial ownership limitation herein contained or to make changes or supplements necessary or desirable to properly give effect to such limitation. Any purported delivery hereunder shall be void and have no effect to the extent (but only to the extent) that, after such delivery, the beneficial ownership of such Holder would exceed the Maximum Percentage. If any delivery owed to the Holder (including, for this purpose, any holder of a beneficial interest therein) hereunder is not made, in whole or in part, as a result of this provision, the Company’s obligation to make such delivery shall not be extinguished and the Company shall make such delivery as promptly as practicable after, but in no event later than three (3) Business Days after, the Holder gives notice to the Company that, after such delivery, its beneficial ownership would not exceed the Maximum Percentage.

2. Adjustment of Exercise Price and Number of Warrant Shares. The Exercise Price and number of Warrant Shares issuable upon exercise of this Warrant are subject to adjustment from time to time as set forth in Sections 2 and 3.

(a) Stock Dividends and Splits. Without limiting any provisions of Section 3, if the Company, at any time on or after the date of the Securities Purchase Agreement, (i) pays a stock dividend on one or more classes of its then outstanding shares of Common Stock or otherwise makes a distribution on any class of capital stock that is payable in shares of Common Stock, (ii) subdivides (by any stock split, stock dividend, recapitalization or otherwise) one or more classes of its then outstanding shares of Common Stock into a larger number of shares or (iii) combines (by combination, reverse stock split or otherwise) one or more classes of its then

outstanding shares of Common Stock into a smaller number of shares, then in each such case the Exercise Price shall be multiplied by a fraction of which the numerator shall be the number of shares of Common Stock outstanding immediately before such event and of which the denominator shall be the number of shares of Common Stock outstanding immediately after such event. Any adjustment made pursuant to clause (i) of this paragraph shall become effective immediately after the record date for the determination of shareholders entitled to receive such dividend or distribution, and any adjustment pursuant to clause (ii) or (iii) of this paragraph shall become effective immediately after the effective date of such subdivision or combination. If any event requiring an adjustment under this paragraph occurs during the period that an Exercise Price is used in any calculation hereunder, then in such calculation such Exercise Price shall be adjusted appropriately to reflect such event.

(b) Number of Warrant Shares. Simultaneously with any adjustment to the Exercise Price pursuant to paragraphs (a) of this Section 2, the number of Warrant Shares that may be purchased upon exercise of this Warrant shall be increased or decreased proportionately, so that after such adjustment the Aggregate Exercise Price payable hereunder for the adjusted number of Warrant Shares shall be the same as the Aggregate Exercise Price in effect immediately prior to such adjustment (without regard to any limitations on exercise contained herein).

(c) Voluntary Adjustment. Subject to compliance with applicable rules of the NASDAQ Capital Market, the Company from time to time may reduce the then current Exercise Price by any amount for any period of time, provided, however, that the period must be at least twenty (20) Business Days, the Exercise Price may not be less than the par value of a share of Common Stock, and the reduction must have been approved by the Company’s board of directors (the “Board”). Whenever the Exercise Price is so reduced, the Company shall mail to the Holders a notice of the reduction at least 15 days before the date the reduced Exercise Price takes effect. The notice shall state the reduced Exercise Price and the period during which it will be in effect. Any such decrease that applies during any Redemption Measurement Period (as defined below) in advance of a redemption by the Company shall continue to apply through the date of redemption.

3. Purchase Rights; Fundamental Transactions.

(a) Fundamental Transactions. Prior to the consummation of each Fundamental Transaction pursuant to which holders of shares of Common Stock are entitled to receive securities or other assets with respect to or in exchange for shares of Common Stock (a “Corporate Event”), the Company shall make appropriate provision to ensure that the Holder will thereafter have the right to receive upon an exercise of this Warrant at any time after the consummation of the applicable Fundamental Transaction but prior to the Expiration Date, in lieu of the shares of the Common Stock issuable upon the exercise of the Warrant prior to such Fundamental Transaction, such shares of stock, securities, cash, assets or any other property whatsoever (including warrants or other purchase or subscription rights) which the Holder would have been entitled to receive upon the happening of the applicable Fundamental Transaction had this Warrant been exercised immediately prior to the applicable Fundamental Transaction (without regard to any limitations on the exercise of this Warrant). Any provision made pursuant to the preceding sentence shall be in a form and substance reasonably satisfactory to the Holder.

(b) Application. The provisions of this Section 3 shall apply similarly and equally to successive Fundamental Transactions and Corporate Events and shall be applied as if this Warrant (and any such subsequent warrants) were fully exercisable and without regard to any limitations on the exercise of this Warrant.

4. Warrant Holder Not Deemed a Shareholder. Except as otherwise specifically provided herein, the Holder, solely in its capacity as a holder of this Warrant, shall not be entitled to vote or receive dividends or be deemed the holder of share capital of the Company for any purpose, nor shall anything contained in this Warrant be construed to confer upon the Holder, solely in its capacity as the Holder of this Warrant, any of the rights of a shareholder of the Company or any right to vote, give or withhold consent to any corporate action (whether any reorganization, issue of stock, reclassification of stock, consolidation, merger, conveyance or otherwise), receive notice of meetings, receive dividends or subscription rights, or otherwise, prior to the issuance to the Holder of the Warrant Shares which it is then entitled to receive upon the due exercise of this Warrant.

5. Reissuance of Warrants.

(a) Transfer of Warrant. If this Warrant is to be transferred, the Holder shall surrender this Warrant to the Company, whereupon the Company will forthwith issue and deliver upon the order of the Holder a new Warrant (in accordance with Section 5(d)), registered as the Holder may request, representing the right to purchase the number of Warrant Shares being transferred by the Holder and, if less than the total number of Warrant Shares then underlying this Warrant is being transferred, a new Warrant (in accordance with Section 5(d)) to the Holder representing the right to purchase the number of Warrant Shares not being transferred.

(b) Lost, Stolen or Mutilated Warrant. Upon receipt by the Company of evidence satisfactory to the Company of the loss, theft, destruction or mutilation of this Warrant (as to which a written certification and the indemnification contemplated below shall suffice as such evidence), and, in the case of loss, theft or destruction, of any indemnification undertaking by the Holder to the Company in customary and reasonable form and, in the case of mutilation, upon surrender and cancellation of this Warrant, the Company shall execute and deliver to the Holder a new Warrant (in accordance with Section 5(d)) representing the right to purchase the Warrant Shares then underlying this Warrant.

(c) Exchangeable for Multiple Warrants. This Warrant is exchangeable, upon the surrender hereof by the Holder at the principal office of the Company, for a new Warrant or Warrants (in accordance with Section 5(d)) representing in the aggregate the right to purchase the number of Warrant Shares then underlying this Warrant, and each such new Warrant will represent the right to purchase such portion of such Warrant Shares as is designated by the Holder at the time of such surrender; provided, however, no warrants for fractional shares of Common Stock shall be given.

(d) Issuance of New Warrants. Whenever the Company is required to issue a new Warrant pursuant to the terms of this Warrant, such new Warrant (i) shall be of like tenor with this Warrant, (ii) shall represent, as indicated on the face of such new Warrant, the right to purchase the Warrant Shares then underlying this Warrant (or in the case of a new Warrant being issued pursuant to Sections 5(a) or 5(c), the Warrant Shares designated by the Holder which, when added to the number of shares of Common Stock underlying the other new Warrants issued in connection with such issuance, does not exceed the number of Warrant Shares then underlying this Warrant), (iii) shall have an issuance date, as indicated on the face of such new Warrant which is the same as the Issuance Date, and (iv) shall have the same rights and conditions as this Warrant.

6. Issuer Redemption Right. In the event that, after the date that is 180 days following the Issuance Date, (a) the Daily VWAP of the Company’s Common Stock for each of ten (10) consecutive Trading Days has exceeded 150% of the Exercise Price (such period the “Redemption Measurement Period”), (b) the Company’s Common Stock has not been suspended and is listed or quoted for trading on the NASDAQ Capital Market or the New York Stock Exchange, and (c) an effective registration statement is in effect covering the Warrant Shares as provided in the Securities Purchase Agreement or all of the Warrant Shares may then be freely sold without any limitations under Rule 144 of the Securities and Exchange Commission, the Company shall have the right, upon twenty (20) Business Days prior notice (“Issuer Redemption Notice”) to Holder, to redeem the Warrant at a redemption price of $0.01 per Warrant.

Upon delivery of an Issuer Redemption Notice, the Holder will have the right to exercise the Warrant for a period commencing on the date such notice is received and terminating at 5:00 p.m. New York Time on the day prior to the closing date indicated on such notice; provided that to the extent a notification under the HSR Act is required for Holder to exercise the Warrant, the right of Holder to exercise the Warrant pursuant to this Section 6 will not terminate until three business days after all applicable waiting periods under the HSR Act shall have expired or been terminated and any applicable Approvals shall have been obtained as set forth in Section 1(a) (the “Extension Period”), and the Company’s right to redeem the Warrant pursuant to this Section 6 shall be suspended until expiration of the Extension Period. To the extent Holder has not elected to exercise the Warrant prior to the expiration of its right as set forth in this Section 6, on the closing date set forth in the Issuer Redemption Notice (as such closing date may be delayed in accordance with the Extension Period, if applicable) the Company shall deliver to Holder the Issuer Redemption Purchase Price via federal funds wire transfer(s) of immediately available funds, in accordance with written instructions provided by Holder to the Company prior to the date thereof, and Holder and the Company agree to enter into such documents as are reasonably customary in order to complete the redemption of the Warrant.

7. Notices. Whenever notice is required to be given under this Warrant, unless otherwise provided herein, such notice shall be given in accordance with Section 9.2 of the Securities Purchase Agreement. The Company shall provide the Holder with prompt written notice of all actions taken pursuant to this Warrant, including in reasonable detail a description of such action

and the reason therefor. Without limiting the generality of the foregoing, the Company will give written notice to the Holder (i) immediately upon each adjustment of the Exercise Price and the number of Warrant Shares, setting forth in reasonable detail, and certifying, the calculation of such adjustment(s) and (ii) at least fifteen (15) days prior to the date on which the Company closes its books or takes a record with respect to any dividend or distribution upon the shares of Common Stock or at least ten (10) Trading Days prior to the consummation of any Fundamental Transaction. To the extent that any notice provided hereunder constitutes, or contains, material, non-public information regarding the Company or any of its subsidiaries, the Company shall simultaneously file such notice with the SEC (as defined in the Securities Purchase Agreement) pursuant to a Current Report on Form 8-K.

8. Amendment and Waiver. Except as otherwise provided herein, the provisions of this Warrant may be amended and the Company may take any action herein prohibited, or omit to perform any act herein required to be performed by it, only if the Company has obtained the written consent of the Holder. No waiver shall be effective unless it is in writing and signed by an authorized representative of the waiving party.

9. Severability. The invalidity or unenforceability of any provision of this Warrant in any jurisdiction shall not affect the validity or enforceability of such provision in any other jurisdiction, or affect any other provision of this Warrant, which shall remain in full force and effect.

10. Governing Law. This Warrant shall be governed by and construed and enforced in accordance with, and all questions concerning the construction, validity, interpretation and performance of this Warrant shall be governed by, the internal laws of the State of New York, without giving effect to any choice of law or conflict of law provision or rule (whether of the State of New York or any other jurisdictions) that would cause the application of the laws of any jurisdictions other than the State of New York.

11. Constructions; Headings. The headings of this Warrant are for convenience of reference and shall not form part of, or affect the interpretation of, this Warrant. Terms used in this Warrant but defined in the Securities Purchase Agreement shall have the meanings ascribed to such terms on the Closing Date (as defined in the Securities Purchase Agreement) in the Securities Purchase Agreement unless otherwise consented to in writing by the Holder.

12. Transfer. This Warrant may not be offered for sale, sold, transferred or assigned by the Holder except in a manner consistent with the restrictive legend on the first page of this Warrant; provided, however, that no such assignment shall relieve the Holder of its obligations hereunder if such assignee fails to perform such obligations.

NOW, THEREFORE, in consideration of the foregoing and of the agreements hereinafter set forth and for other good and valuable consideration the receipt and sufficiency of which are hereby acknowledged, the parties hereto agree as follows:

1. Definitions. In addition to those terms defined elsewhere in this Agreement, the following terms shall have the following meanings when used herein:

“Custodial Funds” shall mean the funds deposited with Escrow Agent pursuant to Section 3 of this Agreement, together with any interest and other income thereon.

“Written Direction” shall mean a written direction executed by a Depositor Representative and directing Escrow Agent to disburse all or a portion of the Custodial Funds or to take or refrain from taking any other action pursuant to this Agreement.

2. Appointment of and Acceptance by Escrow Agent. Depositor hereby appoints Escrow Agent to serve as Escrow Agent hereunder. Escrow Agent hereby accepts such appointment and, upon receipt by wire transfer of the Custodial Funds in accordance with Section 3 below, agrees to hold, invest and disburse the Custodial Funds in accordance with this Agreement.

3. Deposit of Custodial Funds. (i) Simultaneously with the execution and delivery of this Agreement, Depositor will transfer funds in the amount equal to the Initial Deposit Amount, by wire transfer of immediately available funds, to an account designated by Escrow Agent (such account, the “Escrow Account”), (ii) on the date additional Notes are issued pursuant to the Underlying Agreement in connection with the effectiveness of the Registration Statement, Depositor will, with advance written notice to Escrow Agent, deliver cash in an amount determined by Depositor sufficient to pay all required payments of interest (excluding Additional Interest, if any) through the Second Payment Date to Holders of Notes issued pursuant to the terms of the Underlying Agreement, by wire transfer of immediately available funds, to the Escrow Account, and (iii) if additional Notes are issued pursuant to the Underlying Agreement prior to the Second Payment Date, Depositor will, with advance written notice to Escrow Agent, transfer additional funds, by wire transfer of immediately available funds, to Escrow Agent (collectively, the “Custodial Funds”).

4. Disbursement of Custodial Funds upon Written Direction. Following the Second Payment Date, Escrow Agent shall disburse Custodial Funds at any time and from time to time, upon receipt of, and in accordance with, a Written Direction. Such Written Direction shall contain complete payment instructions, including complete wiring instructions or an address to which a check shall be sent. Depositor shall have full responsibility for the accuracy and sufficiency of payment instructions and Escrow Agent shall have no responsibility therefor. The form of Written Direction directing the disbursement of funds may be substantially in the form of Schedule A hereto; provided, however, that other forms of Written Direction may be acceptable to Escrow Agent in its reasonable discretion. Prior to any disbursement, Escrow Agent shall have received reasonable identifying information regarding the recipient such that Escrow Agent may comply with its regulatory obligations and reasonable business practices, including without limitation a completed United States Internal Revenue Service (“IRS”) Form W-9 or W-8, as applicable. All disbursements of funds from the Custodial Funds shall be subject to the fees and claims of Escrow Agent and the Indemnified Parties pursuant to Section 11 and Section 12 below.

5. Regular Interest Payments. On each of November 1, 2016 and the Second Payment Date, Escrow Agent, upon receipt of a Written Direction from the Company in the form of Schedule A hereto, shall disburse Custodial Funds to the Trustee in an amount sufficient to pay the aggregate amount of interest (excluding any Additional Interest) to be paid on the Notes on such date; provided, however that if any Event of Default has occurred and is continuing under Section 6.01 of the Indenture and the Notes have become due and payable by acceleration under Section 6.02 of the Indenture, the Escrow Agent shall, upon receipt of a written notice from the Trustee (unless each of the Trustee and the Escrow Agent are U.S. Bank National Association, in which case no such written notice shall be required), disburse all of the Custodial Funds to the Trustee. The scheduled interest payments due on the Notes through and including the Second Payment Date are to be made from (1) amounts held in the Escrow Account in accordance with the procedures set forth herein and (2) if required, other sources of funds available to Depositor; provided, however, that nothing herein shall be construed as limiting Depositor’s obligation to make all interest payments due on the Notes at the times and in the amounts required under the Notes.

6. Suspension of Performance; Disbursement into Court. If, at any time, (a) there shall exist any dispute with respect to the holding or disposition of all or any portion of the Custodial Funds or any other obligations of Escrow Agent hereunder, (b) Escrow Agent is unable to determine, to Escrow Agent’s sole satisfaction, the proper disposition of all or any portion of the Custodial Funds or Escrow Agent’s proper actions with respect to its obligations hereunder, or (c) Depositor has not, within thirty (30) calendar days of the

furnishing by Escrow Agent of a notice of resignation pursuant to Section 8 hereof, appointed a successor Escrow Agent to act hereunder, then Escrow Agent may, in its sole discretion, take either or both of the following actions: (i) suspend the performance of any of its obligations (including without limitation any disbursement obligations) under this Agreement until such dispute or uncertainty shall be resolved to the sole satisfaction of Escrow Agent or until a successor Escrow Agent shall have been appointed, and (ii) petition (by means of an interpleader action or any other appropriate method) any court of competent jurisdiction, in any venue convenient to Escrow Agent, for instructions with respect to such dispute or uncertainty, and to the extent required or permitted by law, pay into such court, for holding and disposition in accordance with the instructions of such court, all Custodial Funds, after deduction and payment to Escrow Agent of all fees and expenses (including court costs and attorneys’ fees) payable to, incurred by, or expected to be incurred by Escrow Agent in connection with the performance of its duties and the exercise of its rights hereunder. Escrow Agent shall have no liability to Depositor or any other person with respect to any such suspension of performance or disbursement into court, specifically including any liability or claimed liability that may arise, or be alleged to have arisen, out of or as a result of any delay in the disbursement of the Custodial Funds or any delay in or with respect to any other action required or requested of Escrow Agent.

7. Investment of Funds. Based upon Depositor’s prior review of investment alternatives, in the absence of further specific written direction to the contrary, Escrow Agent is directed to invest and reinvest the Custodial Funds in the investment indicated on Schedule B hereto. Depositor may provide Written Direction changing the investment of the Custodial Funds; provided, however, that no investment may be made except in the following: (i) direct obligations of the United States of America or obligations the principal of and the interest on which are unconditionally guaranteed by the United State of America; (ii) U.S. dollar denominated demand and time deposit accounts with a national bank or banking association (including Escrow Agent) which has a rating on its short-term deposits on the date of investment of “A-1” or “A-l+” by Standard &Poor’s and “P-1” by ▇▇▇▇▇’▇ and maturing no more than 360 days after the date of investment (ratings on holding companies are not considered as the rating of the bank); or (iii) money market funds, including funds managed by Escrow Agent or any of its affiliates, rated on the date of investment “AAAm” by Standard &Poor’s or “Aaa-mf” by ▇▇▇▇▇’▇; provided, however, that Escrow Agent will not be directed to invest in investments that Escrow Agent in its sole discretion determines are not consistent with Escrow Agent’s policy or practices. Depositor acknowledges that Escrow Agent does not have a duty nor will it undertake any duty to provide investment advice. To the extent that Depositor directs Escrow Agent to invest in a money market fund as described in clause (iii) of this Section 7, Depositor acknowledges that it has received from Escrow Agent, either directly or via access to a relevant website, a current copy of the prospectus for the investment it has authorized, prior to providing such authorization.

All investments shall be made in the name of Escrow Agent. Notwithstanding anything to the contrary contained herein, Escrow Agent may, without notice to Depositor, sell or liquidate any of the foregoing investments at any time for any disbursement of Custodial Funds permitted or required hereunder. All investment earnings shall become part of the Custodial Funds and investment losses shall be charged against the Custodial Funds. Escrow Agent shall not be liable or responsible for loss in the value of any investment made pursuant to this Agreement, or for any loss, cost or penalty resulting from any sale or liquidation of the Custodial Funds. With respect to any Custodial Funds received by Escrow Agent after twelve o’clock, p.m., St. ▇▇▇▇, Minnesota, local time, Escrow Agent shall not be required to invest such funds or to effect any investment instruction until the next day upon which banks in St. ▇▇▇▇, Minnesota and the New York Stock Exchange are open for business.

8. Resignation of Escrow Agent. Escrow Agent may resign and be discharged from the performance of its duties hereunder at any time by giving thirty (30) days prior written notice to Depositor specifying a date when such resignation shall take effect. Upon any such notice of resignation, Depositor shall appoint a successor Escrow Agent hereunder prior to the effective date of such resignation. If Depositor fails to appoint a successor Escrow Agent within such time, Escrow Agent shall have the right to petition a court of

competent jurisdiction to appoint a successor Escrow Agent, and all costs and expenses (including without limitation attorneys’ fees) related to such petition shall be paid by Depositor. The retiring Escrow Agent shall transmit all records pertaining to the Custodial Funds and shall pay all Custodial Funds to the successor Escrow Agent, after making copies of such records as the retiring Escrow Agent deems advisable and after deduction and payment to the retiring Escrow Agent of all fees and expenses (including court costs and attorneys’ fees) payable to, incurred by, or expected to be incurred by the retiring Escrow Agent in connection with the performance of its duties and the exercise of its rights hereunder. After any retiring Escrow Agent’s resignation, the provisions of this Agreement shall inure to its benefit as to any actions taken or omitted to be taken by it while it was Escrow Agent under this Agreement.

9. Binding Effect; Successors. This Agreement shall be binding upon the respective parties hereto and their heirs, executors, successors or assigns. If Escrow Agent consolidates, merges or converts into, or transfers all or substantially all of its corporate trust business (including the escrow contemplated by this Agreement) to another corporation, the successor or transferee corporation without any further act shall be the successor Escrow Agent.

10. Liability of Escrow Agent. Escrow Agent undertakes to perform only such duties as are expressly set forth herein and no duties shall be implied. Escrow Agent has no fiduciary or discretionary duties of any kind. Escrow Agent shall have no liability under and no duty to inquire as to the provisions of any agreement other than this Agreement, including without limitation any other agreement between the parties hereto or other persons even though reference thereto may be made herein. In no event shall Escrow Agent have any responsibility to determine, investigate or monitor whether any action it is requested to take hereunder fulfills or complies with Depositor’s obligations with respect to the Underlying Agreement or to any third party. Escrow Agent shall not be liable for any action taken or omitted by it in good faith except to the extent that a court of competent jurisdiction determines that Escrow Agent’s gross negligence or willful misconduct was the sole cause of any loss to Depositor. Escrow Agent’s sole responsibility shall be for the safekeeping of the Custodial Funds in accordance with Escrow Agent’s customary practices and disbursement thereof in accordance with the terms of this Agreement. Escrow Agent shall not be charged with knowledge or notice of any fact or circumstance not specifically set forth herein. Escrow Agent may rely upon any notice, instruction, request or other instrument, not only as to its due execution, validity and effectiveness, but also as to the truth and accuracy of any information contained therein, which Escrow Agent shall believe to be genuine and to have been signed or presented by the person or parties purporting to sign the same. In no event shall Escrow Agent be liable for incidental, indirect, special, consequential or punitive damages or penalties (including, but not limited to lost profits), even if Escrow Agent has been advised of the likelihood of such damages or penalty and regardless of the form of action. Escrow Agent shall not be responsible for delays or failures in performance resulting from acts beyond its control, including without limitation acts of God, strikes, lockouts, riots, acts of war or terror, epidemics, governmental regulations, fire, communication line failures, computer viruses, power failures, earthquakes or other disasters. Escrow Agent shall not be obligated to take any legal action or commence any proceeding in connection with the Custodial Funds, any account in which Custodial Funds are deposited, this Agreement or the Underlying Agreement, or to appear in, prosecute or defend any such legal action or proceeding. Escrow Agent may consult legal counsel selected by it in the event of any dispute or question as to the construction of any of the provisions hereof or of any other agreement or of its duties hereunder, or relating to any dispute involving any party hereto, and shall incur no liability and shall be fully indemnified from any liability whatsoever in acting in accordance with the advice of such counsel. Depositor shall promptly pay, upon demand, the reasonable fees and expenses of any such counsel. Depositor agrees to perform or procure the performance of all further acts and things, and execute and deliver such further documents, as may be required by law or as Escrow Agent may reasonably request in connection with its duties hereunder.

Escrow Agent is authorized, in its sole discretion, to comply with final orders issued or process entered by any court with respect to the Custodial Funds, without determination by Escrow Agent of such court’s jurisdiction in the matter. If any portion of the Custodial Funds is at any time attached, garnished or levied upon under any court order, or in case the payment, assignment, transfer, conveyance or delivery of any such property shall be stayed or enjoined by any court order, or in case any order, judgment or decree shall be made or entered by any court affecting such property or any part thereof, then and in any such event, Escrow Agent is authorized, in its sole discretion, to rely upon and comply with any such order, writ, judgment or decree which it is advised by legal counsel selected by it is binding upon it without the need for appeal or other action; and if Escrow Agent complies with any such order, writ, judgment or decree, it shall not be liable to any of the parties hereto or to any other person or entity by reason of such compliance even though such order, writ, judgment or decree may be subsequently reversed, modified, annulled, set aside or vacated.

11. Indemnification of Escrow Agent. From and at all times after the date of this Agreement, Depositor shall, to the fullest extent permitted by law, indemnify and hold harmless Escrow Agent and each director, officer, employee, attorney, agent and affiliate of Escrow Agent (collectively, the “Indemnified Parties”) against any and all actions, claims (whether or not valid), losses, damages, liabilities, penalties, costs and expenses of any kind or nature (including without limitation reasonable attorneys’ fees, costs and expenses) incurred by or asserted against any of the Indemnified Parties, whether direct, indirect or consequential, as a result of or arising from or in any way relating to the negotiation, preparation, execution, performance or failure of performance in connection with this Agreement or any transactions contemplated herein, whether or not any such Indemnified Party is a party to any such action, proceeding, suit or the target of any such inquiry or investigation; provided, however, that no Indemnified Party shall have the right to be indemnified hereunder for any liability finally determined by a court of competent jurisdiction, subject to no further appeal, to have resulted solely from the gross negligence or willful misconduct of such Indemnified Party. Depositor further agrees to indemnify each Indemnified Party for all costs, including without limitation reasonable attorney’s fees, incurred by such Indemnified Party in connection with the enforcement of Depositor’s indemnification obligations hereunder. Each Indemnified Party shall, in its sole discretion, have the right to select and employ separate counsel with respect to any action or claim brought or asserted against it, and the reasonable fees of such counsel shall be paid upon demand by Depositor. The obligations of Depositor under this Section 11 shall survive any termination of this Agreement and the resignation or removal of Escrow Agent.

12. Compensation of Escrow Agent. Depositor agrees to compensate Escrow Agent on demand for its services hereunder in accordance with Schedule C hereto. The obligations of Depositor under this Section 12 shall survive any termination of this Agreement and the resignation or removal of Escrow Agent. Escrow Agent is authorized to, and may disburse to itself from the Custodial Funds, from time to time, the amount of any compensation and reimbursement of reasonable out-of-pocket expenses due and payable hereunder (including any amount to which Escrow Agent or any Indemnified Party is entitled to seek indemnification hereunder). Escrow Agent shall notify Depositor of any disbursement from the Custodial Funds to itself or any Indemnified Party in respect of any compensation or reimbursement hereunder and shall furnish Depositor copies of related invoices and other statements. Depositor hereby grants to Escrow Agent and the Indemnified Parties a security interest in, lien upon and right of offset against the Custodial Funds with respect to any compensation or reimbursement due any of them hereunder (including any claim for indemnification hereunder). If for any reason the Custodial Funds are insufficient to cover such compensation and reimbursement, Depositor shall promptly pay such amounts to Escrow Agent or any Indemnified Party upon receipt of an itemized invoice.

13. Representations and Warranties. Depositor makes the following representations and warranties to Escrow Agent: (a) it has full power and authority to execute and deliver this Agreement and to perform its obligations hereunder; and this Agreement has been duly approved by all necessary action and constitutes its valid and binding agreement enforceable in accordance with its terms; and (b) each of the applicable persons designated on Schedule D hereto have been duly appointed to act as authorized representatives hereunder and individually have full power and authority to execute and deliver any Written Direction, to amend, modify or

waive any provision of this Agreement and to take any and all other actions as authorized representatives under this Agreement, all without further consent or direction from, or notice to, it or any other party, provided that any change in designation of such authorized representatives shall be provided by written notice delivered to each party to this Agreement.

14. Identifying Information. To help the government fight the funding of terrorism and money laundering activities, Federal law requires all financial institutions to obtain, verify, and record information that identifies each person who opens an account. For a non-individual person such as a business entity, a charity, a trust, or other legal entity, Escrow Agent requires documentation to verify its formation and existence as a legal entity. Escrow Agent may ask to see financial statements, licenses, identification and authorization documents from individuals claiming authority to represent the entity or other relevant documentation. Depositor acknowledges that a portion of the identifying information set forth herein is being requested by Escrow Agent in connection with the USA Patriot Act, Pub.L.107-56 (the “Act”), and each agrees to provide any additional information requested by Escrow Agent in connection with the Act or any other legislation or regulation to which Escrow Agent is subject, in a timely manner.

15. Consent to Jurisdiction and Venue. In the event that any party hereto commences a lawsuit or other proceeding relating to or arising from this Agreement, the parties hereto agree to the personal jurisdiction by and venue in the state and federal courts in the State of New York and waive any objection to such jurisdiction or venue. The parties hereto consent to and agree to submit to the jurisdiction of any of the courts specified herein and agree to accept service of process to vest personal jurisdiction over them in any of these courts.

16. Notices. All notices, approvals, consents, requests, and other communications hereunder shall be in writing and shall be delivered by (i) personal delivery, or (ii) national overnight courier service, or (iii) certified or registered mail, return receipt requested, or (iv) facsimile transmission, with confirmed receipt or (v) electronic mail by way of a PDF attachment thereto of a manually executed document. Notice shall be effective upon receipt except for notice by electronic mail, which shall be effective only when the recipient, by return email or notice delivered by other method provided for in this Section 16, acknowledges having received that email (with an automatic “read receipt” or similar notice not constituting an acknowledgement of an email receipt for purposes of this Section 16).

17. Optional Security Procedures. In the event funds transfer instructions, address changes or change in contact information are given (other than in writing at the time of execution of this Agreement), whether in writing, by facsimile or otherwise, Escrow Agent is authorized but shall be under no duty to seek confirmation of such instructions by telephone call-back to the person or persons designated on Schedule D hereto, and Escrow Agent may rely upon the confirmation of anyone purporting to be the person or persons so designated. The persons and telephone numbers for call-backs may be changed only in writing actually received and acknowledged by Escrow Agent and shall be effective only after Escrow Agent has a reasonable opportunity to act on such changes. If Escrow Agent is unable to contact any of the designated representatives identified in Schedule D, Escrow Agent is hereby authorized but shall be under no duty to seek confirmation of such instructions by telephone call-back to any one or more of Depositor’s executive officers (“Executive Officers”), as the case may be, which shall include the titles of Chief Executive Officer, President, Vice President, Treasurer, General Partner and Managing Partner, as Escrow Agent may select. Such Executive Officer shall deliver to Escrow Agent a fully executed incumbency certificate, and Escrow Agent may rely upon the confirmation of anyone purporting to be any such officer. Depositor agrees that Escrow Agent may at its option record any telephone calls made pursuant to this Section. Escrow Agent in any funds transfer may rely solely upon any account numbers or similar identifying numbers provided by Depositor to identify (a) the beneficiary, (b) the beneficiary’s bank, or (c) an intermediary bank. Escrow Agent may apply any of the Custodial Funds for any payment order it executes using any such identifying number, even when its use may result in a person other than the beneficiary being paid, or the transfer of funds to a bank other than the beneficiary’s bank or an intermediary bank designated. Depositor acknowledges that these optional security procedures are commercially reasonable.

18. Amendment, Waiver and Assignment. Subject to the requirements of Article 10 of the Underlying Agreement, none of the terms or conditions of this Agreement may be changed, waived, modified, discharged, terminated or varied in any manner whatsoever unless in writing duly signed by each party to this

Agreement. No course of conduct shall constitute a waiver of any of the terms and conditions of this Agreement, unless such waiver is specified in writing, and then only to the extent so specified. A waiver of any of the terms and conditions of this Agreement on one occasion shall not constitute a waiver of the other terms of this Agreement, or of such terms and conditions on any other occasion. Except as provided in Section 9 hereof and as permitted by the Underlying Agreement, this Agreement may not be assigned by any party without the written consent of the other parties.

19. Severability. To the extent any provision of this Agreement is prohibited by or invalid under applicable law, such provision shall be ineffective to the extent of such prohibition or invalidity, without invalidating the remainder of such provision or the remaining provisions of this Agreement.

Re:

Aradigm Corporation

Ladies and Gentlemen:

This firm has acted as counsel to Aradigm Corporation, a California corporation (the “Company”), in connection with the issuance and sale of $[ ] aggregate principal amount of the Company’s 9.0% Convertible Senior Notes due 2021 (the “Notes”) and warrants (the “Warrants”) to purchase shares of the Company’s Common Stock (the “Warrant Shares”) pursuant to the terms of the Securities Purchase Agreement, dated April 21, 2016 (the “Agreement”), by and between the Company and the purchasers set forth on Exhibit A attached hereto (the “Purchasers”) and an Indenture, dated as of April 25, 2016 (the “Indenture”), among the Company and U.S. Bank National Association, as trustee (the “Trustee”), relating to the Notes. This opinion letter is furnished to you pursuant to the requirements set forth in Section 6.3(d) of the Agreement in connection with a Closing thereunder on the date hereof. Capitalized terms used herein that are defined in the Agreement have the meanings set forth in the Agreement, unless otherwise defined herein.

For purposes of the opinions, which are set forth in paragraphs (a) through (l) below (the “Opinions”), and any other statements made in this letter, we have examined copies of the documents listed on Schedule 1 attached hereto (the “Documents”). We believe the Documents provide an appropriate basis on which to render the Opinions.

In our examination of the Agreement and the other Documents, we have assumed the genuineness of all signatures, the legal capacity of all natural persons, the accuracy and completeness of all of the Documents, the authenticity of all originals of the Documents and the conformity to authentic originals of all of the Documents submitted to us as copies (including telecopies). As to all matters of fact relevant to the Opinions and other statements made herein, we have relied on the representations and statements of fact made in the Documents, we have not independently established the facts so relied on, and we have not made any investigation or inquiry other than our examination of the Documents. The Opinions are given, and other statements are made, in the context of the foregoing.

For purposes of this opinion letter, we have assumed that (i) each party to the Indenture other than the Company has all requisite power and authority under all applicable laws, rules, regulations and governing documents to execute, deliver and perform its obligations under the Indenture, and each of such other parties has complied with all legal requirements pertaining to its status as such status relates to its rights to enforce the Indenture against the Company, (ii) each of such other parties has duly authorized, executed and delivered the Indenture, (iii) each party to the Indenture is validly existing and in good standing in all necessary jurisdictions (except for the Company in the State of California to the extent stated in paragraph (a) below), (iv) the Indenture constitutes a valid and binding obligation of each of such other parties, enforceable against each of such other parties in accordance with its terms, (v) there has been no mutual mistake of fact or misunderstanding, or fraud, duress or undue influence, in connection with the negotiation, execution or delivery of the Indenture, and the conduct of all parties to the Indenture has complied with any requirements of good faith, fair dealing and conscionability, and (vi) there are and have been no agreements or understandings among the parties, written or oral, and there is and has been no usage of trade or course of prior dealing among the parties (and no act or omission of any party), that would, in any such case, define, supplement or qualify the terms of the Indenture. We have also assumed the validity and constitutionality of each relevant statute, rule, regulation and agency action covered by this opinion letter.

For purposes of the opinions set forth in paragraph (g) below, we have made the following further assumptions: (i) that all orders, judgments, decrees, agreements and contracts would be interpreted in accordance with their plain meaning and that the meaning of terms in such agreements and contracts would be what lawyers generally understand them to mean under California Law (as defined below), notwithstanding that such agreements and contracts may be governed by the laws of a different jurisdiction; (ii) that the Company will not in the future take any discretionary action (including a decision not to act) permitted under the Indenture and the Agreement (the “Operative Agreements”) that would result in a violation of law or constitute a breach or default under any order, judgment, decree, agreement or contract; (iii) that the Company will obtain all permits, consents, and governmental approvals required in the future, and take all actions required, which are relevant to performance of the transactions contemplated under the Operative Agreements or performance of the Operative Agreements; and (iv) that all parties to the Operative Agreements will act in accordance with, and will refrain from taking any action that is forbidden by, the terms and conditions of the Operative Agreements.

The Opinions are based as to matters of law solely on applicable provisions of the following, as currently in effect: (i) as to the opinions expressed in paragraphs (a), (b), (c)(i), (c)(iii), (d)(i), (d)(iii), (e), (f)(i), (g)(i), (h) and (l)(i), the California Corporations Code (the “Corporation Act”), (ii) as to the opinions expressed in paragraph (c)(ii), (c)(iv), (d)(ii), f(ii), and (l)(ii), internal New York state law (“New York Law”), (iii) as to the opinions expressed in paragraphs (g)(iii) and (g)(iv), subject to the exclusions and limitations set forth in this opinion letter, internal California state law (“California Law”), (iv) as to the opinions expressed in paragraphs (g)(ii) and (h), subject to the exclusions and limitations set forth in this opinion letter, (A) federal statutes, rules and regulations (“Applicable Federal Law”) and (B) New York and California state statutes, rules and regulations (“Applicable State Law”), (v) as to the opinions expressed in paragraph (i), the Securities Act of 1933 and the rules and regulations promulgated thereunder, (vi) as to the opinions expressed in paragraph (j), the Investment Company Act of 1940 and the rules and regulations promulgated thereunder, and (vii) as to the opinions expressed in paragraph (k), the Trust Indenture Act of 1939 and the rules and regulations promulgated thereunder.

Based upon, subject to and limited by the assumptions, qualifications, exceptions, and limitations set forth in this opinion letter, we are of the opinion that:

(a) The Company is validly existing as a corporation and in good standing as of the date of the Good Standing Certificate under the laws of the State of California.

(b) The Company has the corporate power to execute, deliver and perform its obligations under the Indenture, the Escrow Agreement, the Notes, the Warrants and the Agreement and to own, lease and operate its current properties and to conduct its business as described in the Company SEC Documents. The execution and delivery by the Company of the Agreement, the Escrow Agreement and the Indenture, the performance by the Company of its obligations thereunder, the issuance of the Notes and the Warrants by the Company as contemplated by the Agreement and the issuance of the Note Shares (as defined below) upon conversion of the Notes and the Warrant Shares (as defined below) upon exercise of the Warrants have been duly authorized by all necessary corporate action on the part of the Company.

(ii) The Notes, when executed, authenticated, issued and delivered in the manner provided for in the Indenture and the Agreement, against payment therefor in accordance with the Agreement, will constitute valid and binding obligations of the Company entitled to the benefits of the Indenture and enforceable against the Company in accordance with their terms.

(iii) The Board of Directors has duly adopted resolutions reserving all shares of Common Stock (the “Note Shares”) issuable upon conversion of the Notes. The Note Shares have been duly authorized and, when issued in accordance with the terms of the Notes, will be validly issued, fully paid, non-assessable and free of preemptive rights under the Corporation Act, the Amended and Restated Articles of Incorporation of the Company and Bylaws of the Company and free of preemptive rights and rights to purchase under any Company Contracts.

(iv) The specimen of the certificate referred to in paragraph 7 of Schedule 1 attached hereto conforms in all material respects to the applicable terms contained in the Indenture.

In expressing the foregoing opinions, we have assumed that the Notes conform as to form to the specimen of the certificates referred to in paragraph 7 of Schedule 1 attached hereto, which we have not verified by inspection of the individual Notes.

(d) (i) The Warrants have been duly authorized and executed by the Company.

(ii) The Warrants, when issued and delivered in the manner provided for in the Agreement, against payment therefor in accordance with the Agreement, will constitute valid and binding obligations of the Company enforceable against the Company in accordance with their terms.

(iii) The Board of Directors has duly adopted resolutions reserving the all shares of Common stock (the “Warrant Shares”) issuable pursuant to the terms of the Warrants. The Warrant Shares have been duly authorized and, when issued in accordance with the terms of the Warrants, the Warrant Shares will be validly issued, fully paid, nonassessable and free of preemptive rights under the Corporation Act, the Amended and Restated Articles of Incorporation of the Company and Bylaws of the Company and rights to purchase under any Company Contracts.

(e) The Agreement has been duly authorized, executed and delivered by the Company.

(f) The Indenture (i) has been duly authorized, executed and delivered by the Company and (ii) constitutes a valid and binding obligation of the Company enforceable against the Company in accordance with its terms.

(g) The issuance and sale of the Notes and Warrants, the execution and delivery and consummation by the Company of the Agreement, the Indenture, the Escrow Agreement, the Notes and the Warrants, the performance by the Company of its obligations thereunder and the issuance of the Note Shares upon conversion of the Notes and the issuance of the Warrant Shares upon exercise of the Warrants (assuming that such conversion or exercise, respectively, takes place on the date hereof) do not (i) violate the Corporation Act, or the Amended and Restated Articles of Incorporation or Bylaws of the Company, (ii) violate any provision of Applicable Federal Law or any provision of Applicable State Law, (iii) violate any of the Company Orders, or (iv) breach or constitute a default under any of the Company Contracts (except that we express no opinion with respect to any matters that would require a mathematical calculation or a financial or accounting determination).

(h) No approval or consent of, or registration or filing with, any governmental agency is required to be obtained or made by the Company under Applicable Federal Law or Applicable State Law or under the Corporation Act in connection with the issuance and sale of the Notes and the Warrants, the execution and delivery and consummation by the Company of the Agreement, the Indenture, the Escrow Agreement, the Notes and the Warrants and the issuance of the Note Shares upon conversion of the Notes and the issuance of the Warrant Shares upon exercise of the Warrants other than (a) for the filing of a Form D pursuant to Securities and Exchange Commission Regulation D and (b) for any necessary filings under applicable blue sky laws.

(i) Based upon and assuming the accuracy of the representations and warranties, and assuming compliance with the covenants and agreements, of the Company and the Purchasers contained in the Agreement, the offer, sale and delivery of the Notes by the Company to Purchasers under the Agreement are not required to be registered under the Securities Act of 1933.

(j) The Company is not, and, after giving effect to the offering and sale of the Notes and the Warrants and the application of the proceeds therefrom, will not be, required to register as an “investment company” under the Investment Company Act.

(k) No qualification of the Indenture under the Trust Indenture Act of 1939, as amended, is required in connection with the purchase of the Notes by the Purchasers in the manner contemplated by the Agreement.

(l) The Escrow Agreement (i) has been duly authorized, executed and delivered by the Company and (ii) constitutes a valid and binding obligation of the Company enforceable against the Company in accordance with its terms.

(m) Except as waived in writing or as contemplated by the Agreement, the Company Contracts do not contain any rights of a holder of securities of the Company that require the Company to include any securities of the Company owned by such person in the securities to be registered pursuant to any Registration Statement contemplated by the Agreement.

The opinions expressed in paragraphs (c)(ii), (d)(ii), (f)(ii) and (l) above with respect to the enforceability of the Notes, the Warrants and the Indenture shall be understood to mean only that if there is a default in performance of an obligation, (i) if a failure to pay or other damage can be shown and (ii) if the defaulting party can be brought into a court which will hear the case and apply the

governing law, then, subject to the availability of defenses, and to the exceptions elsewhere set forth in this opinion letter, the court will provide a money damage (or perhaps injunctive or specific performance) remedy.

Our opinion in paragraph (h) above is not intended to cover and should not be viewed as covering approvals, consents, registrations and filings required for the conduct of the Company’s business generally (i.e., that would be required in the course of its business in the absence of entering into the Agreement, the Indenture, the Notes and the Warrants).

In addition to the assumptions, qualifications, exceptions and limitations elsewhere set forth in this opinion letter, our opinions expressed above are also subject to the effect of: (i) bankruptcy, insolvency, reorganization, receivership, moratorium and other laws affecting creditors’ rights (including, without limitation, the effect of statutory and other law regarding fraudulent conveyances, fraudulent transfers and preferential transfers); and (ii) the exercise of judicial discretion and the application of principles of equity, good faith, fair dealing, reasonableness, conscionability and materiality (regardless of whether the applicable agreements are considered in a proceeding in equity or at law).

We express no opinion in this letter as to any other statutes, rules and regulations not specifically identified above as being covered hereby (and in particular, we express no opinion as to any effect that such other statutes, rules and regulations may have on the opinions expressed herein). We express no opinion in this letter as to securities statutes, rules or regulations (except to the extent stated in paragraphs (i), (j) and (k)), antitrust, unfair competition, banking, or tax statutes, rules or regulations, or statutes, rules or regulations of any political subdivision below the state level. The opinions set forth in paragraphs (c), (f), (g), and (h) are based upon a review of only those statutes, rules and regulations (not otherwise excluded in this letter) that, in our experience, are generally recognized as applicable to the transactions of the type covered by the Agreement and to the role of the Company in such transactions.

We assume no obligation to advise you of any changes in the foregoing subsequent to the delivery of this opinion letter. This opinion letter is being furnished by us only to you in connection with the Closing under the Agreement on the date hereof, is solely for your benefit in your capacity as the Purchasers or placement agent, as applicable, and should not be quoted in whole or in part or otherwise be used, relied upon, or referred to, for any other purpose or by any other person (including any person purchasing any of the Notes or the Warrants from you), and should not be filed with or furnished to any governmental agency or other person or entity, without the prior written consent of this firm.

Very truly yours,
