discretion elect to require payment solely in cash.  The date of any such
prepayment shall be referred to as the "Prepayment Date."

          (b) Promptly after the commencement thereof, notice of all actions,
suits and proceedings before any Governmental Authority, affecting Borrower,
which, if determined adversely to Borrower, could have a Material Adverse
Effect.

          (c) With reasonable promptness, such other information regarding the
business, operations, and financial condition of Borrower as Lender may from
time to time reasonably request.

     4.2  LICENSES AND PERMITS

     Maintain all material Governmental Approvals and all related or other
material agreements necessary for Borrower to operate its business, as it now
exists or as it may be modified or expanded as contemplated by the Transaction

relating to the operations, facilities, or activities of Borrower.

     4.3  MAINTENANCE OF PROPERTIES

     Keep the Manufacturing Facility and Borrower's material properties in good
repair and in good working order and condition, in a manner consistent with past
practices and comparable to industry standards; from time to time make all
appropriate and proper repairs, renewals, replacements, additions, and
improvements thereto; and keep them and all material equipment that may now or
in the future be subject to compliance with any Applicable Laws in full
compliance with such Applicable Laws.

     Duly pay and discharge all (a) taxes, assessments, levies, and any other
charges of Governmental Authorities imposed on or against Borrower or its
property or assets, or upon any property leased by Borrower, prior to the date
on which penalties attached thereto, unless and to the extent only that such
taxes, assessments, levies, and any other charges of Governmental Authorities,
after written notice thereof having been given to Lender, are being contested in
good faith and by appropriate proceedings; (b) claims allowed by Applicable
Laws, whether for labor, materials, rentals, or anything else, which could, if
unpaid, become a lien or charge upon Borrower's property or assets or the
outstanding capital stock of Borrower or result in a Material Adverse Effect
(unless and to the extent only that the validity thereof is being contested in
good faith and by appropriate proceedings after written notice thereof has been
given to Lender); (c) trade bills in accordance with the terms thereof or

extended. In the event any charge is being contested by Borrower as allowed
above, Borrower shall establish adequate reserves against possible liability
therefor.

     4.5  INSURANCE

     Maintain insurance upon Borrower's properties and business in accordance
with prevailing industry standards, including, without limitation, general
liability insurance (including products liability and personal injury liability

policies shall require at least thirty (30) days' prior written notice to Lender
concerning cancellation thereof.  At least annually and otherwise upon request
by Lender, Borrower shall deliver to Lender a certificate or certificates of
insurance evidencing the required coverage.  Compliance herewith in no way
limits Borrower's indemnity obligations, except to the extent that Borrower's
insurance company actually pays Lender or its Affiliates amounts which Borrower
would otherwise pay Lender.

and correct entries will be made of all material dealings or transactions in
relation to the business and affairs of Borrower.

representative of Lender to examine the books of account and other records and
files of Borrower relevant to the Loan, and to discuss the affairs, business,
finances, and accounts of Borrower with its senior officers and inspect the
Manufacturing Facility.

     4.8  CORPORATE EXISTENCE

     Maintain and preserve the corporate existence of Borrower.

     Upon receipt of a written notice of loss, theft, destruction, or mutilation
of the Note, and upon surrendering such Note for cancellation if mutilated,
execute and deliver a new Note of like tenor in lieu of such lost, stolen,
destroyed, or mutilated Note.  Lender hereby agrees to indemnify and hold
Borrower harmless from all 

                                      -8-

 
claims, losses, and damages (including reasonable attorneys' fees) incurred by
Borrower as a result of loss, theft, or destruction of the Note.

     4.10  OTHER AGREEMENTS

     Comply with all covenants and agreements set forth in or required pursuant
to any of the other Loan Documents or Transaction Documents.

     4.11  FURTHER ASSURANCES

duly executed and delivered to Lender such further instruments, agreements, and
documents and do or cause to be done such further acts as may be necessary to
carry out more effectively the provisions and purpose of this Agreement and the
other Loan Documents.

5.   NEGATIVE COVENANTS OF BORROWER

     Borrower covenants and agrees that until the Loan, together with interest
thereon, and all other obligations incurred hereunder are paid or satisfied in
full, Borrower shall not, without the prior written consent of Lender, which
consent shall not be unreasonable withheld or delayed:

capital to any of Borrower's shareholders;

     (b) wind up, liquidate, or dissolve Borrower's affairs or enter into any
transaction to dispose of (or agree to do any of the foregoing at any time) all
or substantially all of its assets;

     (c) grant any mortgage on or any security interest in any lease agreement
relating to the Manufacturing Facility; or

furniture or fixtures associated with the Manufacturing Facility; provided,
however, that Borrower may grant such a security interest to any entity
providing financing to facilitate the acquisition of such equipment, personal
property, furniture or fixtures, limited, however, to the property so acquired
and to the acquisition price thereof.

6.   REPRESENTATIONS AND WARRANTIES OF BORROWER

     Borrower hereby represents and warrants to Lender as of the date hereof and
the date of each funding of the Loan as follows:

                                      -9-

          VALIDITY

     Borrower is a corporation organized and validly existing under the laws of
the state of Washington and has all requisite corporate power and authority to
own its properties and carry on its business as currently conducted and as
contemplated by the Transaction Documents.  Borrower is duly qualified to
transact business and is in good standing as a foreign corporation in each
jurisdiction in which the failure to so qualify would have a material adverse
effect on its financial condition, results of operations, business or properties
(a "Material Adverse Effect").  Borrower has previously provided the Investor

its Amended and Restated Bylaws as in effect on the date of this Agreement.

corporate action on the part of Borrower, its officers, directors and
shareholders necessary for the authorization, execution and delivery of this
Agreement and the other Loan Documents and the transactions contemplated herein
and therein and the performance of all obligations of Borrower hereunder and
thereunder have been taken or will be taken prior to the initial funding of the
Loan.  Borrower, its officers, directors, and shareholders will have taken all
corporate action necessary for the authorized issuance of Common Stock
hereunder, if any, prior to the Payment Date or Prepayment Date on which such
Common Stock is to be issued.  Each of the Agreement and the other Loan
Documents have been duly executed and delivered by Borrower and constitutes a
valid and legally binding obligation of Borrower, enforceable in accordance with
its terms, except as (a) such enforceability may be limited by bankruptcy,
insolvency or similar laws affecting creditors' rights generally and (b) the
availability of equitable remedies may be limited by equitable principles of
general applicability.

     6.3  GOVERNMENTAL CONSENTS

     No consent, approval, order or authorization of, or registration,
qualification, designation, declaration or filing with, any Governmental
Authority on the part of Borrower is required in connection with the
consummation of the transactions contemplated by this Agreement or the other
Loan Documents.

     There is no action, suit, claim, proceeding or investigation pending or, to
Borrower's knowledge, threatened against Borrower that relates to or challenges
the legality, validity or enforceability of this Agreement or the other Loan
Documents or that could either individually or in the aggregate have a Material
Adverse Effect, nor has the U.S. Food and Drug Administration taken any action
with respect to the Licensed Products which would prohibit the marketing of the
Licensed Products if developed as contemplated by the License and Collaboration
Agreement.  Borrower is not a party to or subject to the provisions of any
order, writ, injunction, judgment or decree of any court or other Governmental
Authority that could have a Material Adverse Effect.

     6.5  COMPLIANCE WITH OTHER INSTRUMENTS

     Borrower is not in violation of any provision of its Restated Articles of
Incorporation or its Amended and Restated Bylaws or in violation or default of
any provision of any instrument, Applicable Lawjudgment, order, writ, decree or
contract to which it is a party or by which it is bound, which violation or
default would adversely affect the legality, validity, or enforceability of this
Agreement or the other Loan Documents or have a Material Adverse Effect.  The
execution, delivery and performance of this Agreement or the other Loan
Documents and the consummation of the transactions contemplated hereby will not
require any consent under or be in conflict with or constitute, with or without
the passage of time or the giving of notice or both, either a violation or
default under any such provision, instrument, Applicable Law, judgment, order,
writ, decree or contract or give rise to a right to terminate or accelerate any
contract or an event which results in the creation of any lien, charge or
encumbrance upon any of Borrower's assets.

     6.6  SEC REPORTS; FINANCIAL STATEMENTS

     Borrower has furnished the Investor with a true and complete copy of each
report, schedule, registration statement and definitive proxy statement filed by
Borrower with the Securities and Exchange Commission (the "SEC") since December
31, 1997 (the "SEC Documents"), which are all the documents that Borrower has
been required to file with the SEC during such period.  As of their respective
dates, the SEC Documents complied with the requirements of the Securities Act of
1933, as amended (the "Securities Act"), or the Securities Exchange Act of 1934,
as amended, as applicable, and the rules and regulations of the SEC thereunder,
and none of the SEC Documents contained any untrue statement of a material fact
or omitted to state a material fact required to be stated therein or necessary
in order to make the statements therein, in light of the circumstances under
which they were 

                                      -11-

 
made, not misleading. The financial statements of Borrower included in the SEC
Documents are complete in all material respects and were prepared in accordance
with generally accepted accounting principles applied on a consistent basis
during the periods involved (except as may be indicated in the notes thereto or,
in the case of unaudited financial statements, as permitted by Form 10-Q of the
SEC) and fairly present (subject, in the case of unaudited financial statements,
to normal recurring audit adjustments) the financial position of Borrower at the
dates thereof and the results of its operations and changes in financial
position for the periods then ended.

     6.7  COMPLIANCE WITH LAWS

     Borrower has complied, and is in compliance with, all Applicable Laws and
all federal, state, county, local and foreign decrees and orders, and possesses
all governmental franchises, permits and consents, and has made all governmental
filings and declarations, applicable to the operation of its business, to its
employees, or to the real property and the personal property that it owns or
leases (including, without limitation, all such Applicable Laws, decrees and
orders relating to pharmaceutical, antitrust, consumer protection, currency
exchange, environmental protection, equal opportunity, health, occupational
safety, pension, securities and trading-with-the-enemy matters), the failure to
comply with which would, individually or in the aggregate, have a Material
Adverse Effect.  Borrower has not received any notification of any asserted
present or past unremedied failure by Borrower to comply with any of such
Applicable Laws, decrees or orders.

     6.8  CHANGES

     Since June 30, 1998 there has not been:

a Material Adverse Effect.

against Borrower any such proceeding that remains undismissed for a period of
sixty (60) days or more, or an order, judgment, or decree approving the petition
in any such proceeding is entered; or if Borrower by any act or failure to act
indicates its consent to, approval of, or acquiescence in, any such proceeding
or any appointment of any receiver, liquidator, or trustee of or for it or for
any substantial part of its property or assets, suffers any such appointment to

     7.2  ACCELERATION; REMEDIES

     Upon the occurrence of any Event of Default or at any time thereafter, if
any Event of Default is then continuing, Lender may, by written notice to
Borrower, declare the entire unpaid principal balance or any portion of the
principal balance of the Note and interest accrued thereon to be immediately due
and payable by the maker thereof; and such principal and interest shall
thereupon become and be immediately due and payable, without presentation,
demand, protest, notice of protest, or other 

                                      -14-

 
notice of dishonor of any kind, all of which are hereby expressly waived by
Borrower. Lender may proceed to protect and enforce its rights hereunder in any
manner or order it deems expedient without regard to any equitable principles of
marshaling or otherwise. All rights and remedies given by the Loan Documents are
cumulative and not exclusive of any thereof or of any other rights or remedies
available to Lender; no course of dealing between Borrower and Lender or any
delay or omission in exercising any right or remedy shall operate as a waiver of
any right or remedy; and every right and remedy may be exercised from time to
time and as often as deemed appropriate by Lender. Lender shall apply any
proceeds received by it in connection with its exercise of rights or remedies
first to the payment of reasonable costs and expenses incurred by it in
- -----
connection with such exercise, including, without limitation (to the extent
permitted by law), reasonable attorneys' fees and legal expenses, and second to
                                                                      ------
the payment of the outstanding Loan amount (and accrued interest), as Lender in
its sole discretion may elect. Borrower shall remain liable to Lender for and
shall pay to Lender any deficiency which may remain between the amount of
proceeds received and the sum owed to Lender. Upon the occurrence and during the
continuance of any Event of Default, Lender or any of its Affiliates may at any
time, and from time to time, without notice to Borrower, set-off and apply any
and all amounts at any time owing by Lender or any of its Affiliates to or for
the credit of Borrower against any and all obligations of Borrower now or
hereafter existing under the Loan Documents, irrespective of whether or not
Lender shall have made any demand under the Loan Documents or the obligations
thereunder remain unmatured. Although Borrower waives any right to receive
notice of Lender's actions under this Section, Lender agrees to notify Borrower
promptly after any such set-off and application, provided that the failure to
give such notice shall not affect the validity of such set-off and application.
Lender's rights hereunder are in addition to any of Lender's other rights or
remedies.

reasonable attorneys' fees and costs.  Reasonable attorneys' fees shall include,

in any case without regard to the identity of the prevailing party.

     8.3  NO WAIVER

     No failure or delay on the part of Lender or the holder of the Note in
exercising any right, power, or privilege hereunder and no course of dealing
between Borrower and Lender or the holder of the Note shall operate as a waiver
thereof; nor shall any single or partial exercise of any right, power, or
privilege hereunder preclude any other or further exercise thereof or the
exercise of any right, power, or privilege.  The rights and remedies herein
expressly provided are cumulative and not exclusive of any rights or remedies
that Lender or any subsequent holder of the Note would otherwise have.  No
notice to or demand on Borrower in any case shall entitle Borrower to any other
or further notice or demand in similar or other circumstances or shall
constitute a waiver of the right of Lender to any other or further action in any
circumstances without notice or demand.

their respective obligations hereunder or under any of the other Loan Documents
without the prior written consent of the other party, except that Lender may
assign and delegate its rights and obligations hereunder to an Affiliate so long
as Lender remains primarily liable hereunder.

                                      -16-

provisions hereof are severable.

                               November 23, 1998


Medeva PLC
10 St. James's Street
London, United Kingdom SW1A 1EF

RE:  CREDIT AGREEMENT, DATED AS OF NOVEMBER 23, 1998, BY AND BETWEEN TARGETED
     GENETICS CORPORATION AND MEDEVA PLC

Ladies and Gentlemen:

     We have acted as counsel to Targeted Genetics Corporation, a Washington
corporation (the "Company"), in connection with the transactions contemplated by
the Credit Agreement dated as of November 23, 1998 (the "Credit Agreement") by
and between the Company and Medeva PLC, a public limited liability company
organized under the laws of England ("Lender").  We are rendering this opinion
letter to you at the request of the Company pursuant to Section 3(d) of the
Credit Agreement.  Except as otherwise indicated herein, capitalized terms used
and not otherwise defined in this opinion letter have the meanings assigned to
such terms in the Credit Agreement.

     For purposes of the opinions set forth below, we have examined copies only
of (a) the Credit Agreement and the Note between the Company and the Lender,
(collectively, the "Transaction Documents"), (b) the Company's Articles of
Incorporation, as amended and filed with the Washington Secretary of State (the
"Company's Articles of Incorporation") and Bylaws, as amended (the "Company's
Bylaws"), (c) certificates of government officials, corporate officers and other
representatives of persons referred to herein, (d) certificates provided to us
in connection with delivery of this letter by the Chief Financial Officer and
the Secretary of the Company ("Officer's Certificates"), and (e) such other
documents as we have deemed necessary for purposes of the opinions expressed
below.

     As to matters of fact bearing upon the opinions set forth below, we have,
with your consent, relied solely upon, and have not independently verified the
accuracy of, the representations, warranties and other statements of all parties
contained in the Transaction Documents and matters of fact set forth in
certificates of government 

                                      -20-

 
officials, corporate officers and other representatives of persons referred to
herein. During the course of our representation of the Company, nothing came to
our attention that has led us to believe that the representations, warranties or
statements upon which we have relied for the purposes of rendering these
opinions are inaccurate in any material respect.

     In rendering such opinions, we have further relied upon the following
assumptions, the accuracy of which we have not independently verified:

           (i) Each signature is genuine; each document submitted to us as an
               original is authentic; and each document submitted to us as a
               copy conforms to the original.

          (ii) All natural persons who executed or delivered the Transaction
               Documents on behalf of the Company have sufficient legal capacity
               to perform such acts.

         (iii) The factual representations and warranties in the Transaction
               Documents of each of the parties thereto are true, and the facts
               and circumstances contemplated pursuant to the Transaction
               Documents are as contemplated therein.

          (iv) Each certificate provided by a governmental official reviewed
               by us for the purpose of rendering this opinion letter is
               accurate, complete and authentic, and all official public records
               (including their proper indexing and filing) are accurate and
               complete.

           (v) All statutes, judicial and administrative decisions, and rules
               and regulations of governmental agencies, constituting the law
               examined by us, are generally available (i.e., in terms of access
               and distribution following publication or other release) to
               lawyers practicing in such jurisdiction, and are in a format that
               makes legal research reasonably feasible.

          (vi) The constitutionality or validity of the relevant statute,
               rule, regulation or agency action is not in issue unless a
               reported decision in the opining jurisdiction has specifically
               addressed but not resolved, or has established, its
               unconstitutionality or invalidity.

         (vii) The directors of the Company are Jack L. Bowman, H. Stewart
               Parker, Jeremy Curnock Cook, Mark P. Richmond, Martin P. Sutter,
               James D. Grant, and Louis P. Lacasse and there are 

                                      -21-

 
               presently no vacancies on the Board of Directors of the Company.

     Based upon the examinations, assumptions, qualifications and exceptions
stated herein, we are of the opinion that:

     1.  The Company is a corporation validly existing under the laws of the
state of Washington.

     2.  The Company has the requisite corporate power and corporate authority
to execute, deliver and perform its obligations under the Transaction Documents
and, to the extent material to the Company's respective performance of its
obligations thereunder, to own its properties and to carry on its business as it
is now conducted.

     3.  The Company has authorized, by all necessary corporate action on the
part of the Company, the execution, delivery and performance of each of the
Transaction Documents.

     4.  The execution, delivery and performance by the Company of the
Transaction Documents do not conflict with or result in a violation of the
Company's Articles of Incorporation or Bylaws or any agreement listed as an
Exhibit to the Company's most recent Form 10-K, as filed with the Securities and
Exchange Commission.

     5.  The execution, delivery and performance by the Company of the
Transaction Documents are not prohibited by, nor do they result in the
imposition of a fine, penalty or other similar sanction for a violation under,
the provisions of the laws of the state of Washington.

     6.  Except as disclosed in the Credit Agreement, the execution and delivery
to Lender by the Company of the Transaction Documents and the performance by the
Company of its obligations thereunder do not require under present law any
filing or registration by the Company with, or approval or consent to the
Company of, any governmental agency or authority in the state of Washington that
has not been made or obtained.

     7.  The Common Stock that may be issued by the Company as repayment or
prepayment of all or any part of the Loan pursuant to Section 2.8 of the Credit
Agreement has been duly reserved for issuance and when issued in accordance with
the Credit Agreement it will be duly and validly issued, fully paid and
nonassessable.

                                      -22-

 
     8.  The Transaction Documents have been duly and validly executed.

     The opinions expressed above are subject to the following exclusions and
qualifications:

          a.  Our opinions are as of the date hereof, and we have no
responsibility to update this opinion for events and circumstances occurring
after the date hereof or as to facts relating to prior events that are
subsequently brought to our attention.  We do not undertake to advise you of any
changes in law.

          b.  We are qualified to practice law in the state of Washington and do
not express any opinions in this letter concerning any laws other than
Washington state law; and we express no opinion with respect to the laws,
regulations or ordinances of any county, municipality, or governmental
subdivision or agency of whatever description or character, or with respect to
matters that may be affected by the laws of any other jurisdiction or that may
be affected by pending or proposed legislation.

          c.  Notwithstanding that the opinions expressed herein may refer to
any party other than the Company, we are not representing, and do not purport to
represent, such party in connection with the transaction described herein.

          d.  In giving the opinion that the Company is validly existing under
