                              EMPLOYMENT AGREEMENT

      THIS AGREEMENT is made this the 1st day of July, 2003, by and between
Breda Telephone Corp., an Iowa Corporation, hereinafter referred to as "Breda",
and Jane Morlok, the Chief Financial Officer and Co-Chief Executive Officer,
hereinafter referred to as "Jane".

      WHEREAS, Jane is presently employed by Breda pursuant to an Employment
Agreement dated the 1st day of April, 2002, and

      WHEREAS, the parties hereto desire to terminate that agreement and enter
into a new agreement based on the terms and conditions set forth below.

      NOW, therefore in consideration of the mutual covenants and obligations
hereinafter set forth, the parties agree as follows:

      1. Termination of Old Employment Agreement. The parties hereto agree that
the old Employment Agreement shall be terminated concurrently with the execution
of this agreement and shall be of no further force or effect. The parties hereto
waive and release all rights that they may have under the old Employment
Agreement as of the date hereof.

      2. Employment and Duties. Breda employs Jane in the capacity as Chief
Financial Officer and Co-Chief Executive Officer, subject to the control of the
Board of Directors. Jane shall perform such other and additional duties as shall
be assigned to her from time to time by such Board of Directors.

      3. Compensation. During the term of this agreement, Breda shall pay Jane a
salary and bonus as follows:

            (a)   Salary. Jane's yearly salary for the year beginning the 1st
                  day of January, 2003, to the 31st day of December, 2003, shall
                  be $81,500.00. Jane's yearly salary for the year beginning the
                  1st day of January, 2004, to the 31st day of December, 2004,
                  shall be $83,000.00. Jane's yearly salary for the year
                  beginning the 1st day of January, 2005, to the 31st day of
                  January, 2005, shall be $84,500.00. Jane's yearly salary will
                  be payable in accordance with Breda's regular payroll
                  procedures.

            (b)   Bonus. The system for determining a bonus for Jane has been
                  established by the Board of Directors. For the year beginning
                  the 1st day of January, 2003, and ending the 31st day of
                  December, 2003, a copy of the procedure is attached hereto and
                  marked as "Attachment A", and made a part hereof. The final
                  determination as to the amount of the bonus rests solely in
                  the discretion of the Board of Directors. However, the Board
                  does hereby agree that the methodology and procedures will
                  follow the general guidelines as outlined in the "Attachment
                  A".

            (c)   Additional Bonus. The year beginning the 1st day of January,
                  2004, and ending the 31st day of December, 2004, and for the
                  year beginning the 1st day of January, 2005, and ending the
                  31st day of December, 2005, the amount of bonus that Jane can
                  earn will increase by 5% to 25% of her annual salary. This
                  additional bonus will be determined by measuring (i) cash flow
                  generated from operations; and (ii) value added calculations.

      4. Other Employee Benefits. Jane shall be entitled to all employee
benefits extended, from time to time, to all full time employees of Breda.

      5. Extent of Service. Jane shall devote her entire attention and energy to
the business and affairs of Breda, and should not be engaged in any other
business activity, whether or not such business activity is a pursuit for gain,
profit or other pecuniary advantage, unless Breda consents to Jane's involvement
in such business activity. This restriction shall not be construed as preventing
Jane from investing her assets in a form or manner that would not require Jane's
services in the operation of any of the company in which such investments are
made.

      6. Term. The term of this agreement shall be for three years, beginning on
the 1st day of January, 2003, and ending on the 31st day of December, 2005.

      7. Termination Without Cause. Breda may terminate this agreement at any
time, without cause, by giving thirty (30) days written notice to Jane. In that
event, if requested by Breda, Jane shall continue to render her services and
shall be paid her regular compensation up to the date of termination. In
addition, Jane shall be paid on the date of termination the severance allowance
equal to the amount remaining to be paid under this contract.

      Jane may terminate this agreement, at any time, by giving sixty (60) days
notice to Breda. In that event, Breda shall pay Jane her compensation up to the
date of termination. Jane shall not be entitled to any severance payment and
will not be considered for any performance upon her voluntary termination.

      8. Termination for Cause. Breda may terminate this agreement for cause
upon five (5) days written notice to Jane stating the reason for said
termination. Matters which would be considered terminable for cause would
include, but not be limited to:

            (a)   Fraud or theft;

            (b)   Falsifying records;

            (c)   Refusal to carry out a specific order of the Board of
                  Directors;

            (d)   Abuse, discrimination, or harassment of another employee;

            (e)   Unauthorized dissemination of records or information;

            (f)   Divulging confidential information;

            (g)   Possession of illegal drugs or weapons while on Breda
                  property;

            (h)   Conviction of a crime, the nature of which would be calculated
                  to render an employee undesirable as a co-manager and
                  detrimental to the best interest of the company; and

                                      E-8
<PAGE>

            (i)   Using or possessing intoxicants or narcotics of any kind while
                  on company premises or being at work under the influence of
                  such substances.

      9. Illness or disability. If Jane is absent from her employment by reason
of illness or other incapacity for more than twenty-six (26) consecutive weeks,
Breda may, after such twenty-six (26) consecutive weeks, but only if Jane then
fails to return to active employment with Breda, terminate Jane's employment by
furnishing her with notice of termination. Breda shall pay Jane compensation
during any period of illness or incapacity in accordance with Breda's sick pay
policy then in effect.

      10. Death. If Jane's employment terminates by reason of her death, Breda
shall only be obligated to make the payments required under its pension plan.

      11. Restrictive Covenants. During the term of this agreement, and for a
period of one (1) year hereafter, Jane shall not, either as an individual or on
her own account, or as a partner, joint venture, employee, agent, officer,
director or shareholder, directly or indirectly (a) enter into or engage in any
business competitive with that of Breda within fifty (50) mile area in which
Breda is then doing business; and (b) solicit or attempt to solicit any of
Breda's customers with the intent or purpose to perform services for such
customers which are the same or similar to those provided to the customer by
Breda, or to sell to such customers goods which are the same or similar to those
provided to customers by Breda.

      12. Confidential Information. Jane acknowledges and agrees that all
information of a technical or business nature, such as know how, trade secrets,
business plans, data, processes, techniques, customer information, inventions,
discoveries and devices, acquired by Jane in the course of her employment under
this agreement, is valuable, proprietary information of Breda. Jane agrees that
such confidential information whether in written, verbal or model form shall not
be disclosed to anyone outside of the employment of Breda, without Breda's
written consent.

      13. Return of Documents. Upon the termination of Jane's employment with or
without cause, Jane shall immediately return and deliver to Breda and shall not
retain any originals or copies of any books, papers, price lists, customer
contacts, bids, customer lists, files, notebooks or any other documents
containing any of the confidential information or otherwise relating to Jane's
performance of duties under this agreement. Jane further acknowledges and agrees
that all such documents are Breda's sole and exclusive property.

      14. Expenses. Jane is authorized to incur only such expenses for promoting
and continuing Breda's business as Breda may from time to time deem reasonable
and appropriate. Breda will reimburse Jane for all such expenses upon Jane's
presentation of receipts and an itemized accounting therefore.

      15. Construction of Agreement. This agreement shall be interpreted,
constructed and governed by and under the laws of the State of Iowa. If any
provision or clause of this agreement or the application thereof to either party
is held to be invalid by a court of competent

                                      E-9
<PAGE>

jurisdiction, then such provision shall be severed therefrom and such invalidity
shall not effect any other provision of this agreement.

            (a)   In the event that the provisions of paragraph 11 shall ever be
                  deemed to exceed the time or geographical limits permitted by
                  applicable law, then such provision shall be reformed to the
                  maximum time and geographical limits permitted by applicable
                  law.

            (b)   The representations, warranties, covenants and agreements of
                  the parties shall be revived continuously during the Term, or
                  in consideration of the compensation paid to Jane, and shall
                  survive the termination of this agreement.

            (c)   This agreement contains the entire agreement between the
                  parties hereto with respect to the subject matter hereof, and
                  there are no understandings, representations or warranties of
                  any kind between the parties except as expressly set forth
                  herein.

            (d)   Neither this agreement nor any right or obligation of Jane
                  hereunder may be assigned by Jane without the prior written
                  consent of Breda.

            (e)   Subject thereto, this agreement and the covenants and
                  conditions herein contained shall enure to the benefit of and
                  shall be binding upon the parties hereto and their respective
                  successors and permitted assigns.

      1. Issuance. This Warrant is issued to Rodman & Renshaw on this 25th day
of June, 2003 (the "Original Issue Date") by RepliGen Corporation, a Delaware
corporation (hereinafter with its successors called the "Company").

      2. Purchase Price; Number of Shares. Subject to the terms and conditions
hereinafter set forth, the registered holder of this Warrant (the "Holder"),
commencing on the date hereof, is entitled upon surrender of this Warrant with
the subscription form annexed hereto duly executed, at the office of the
Company, 41 Seyon Street, Building 1, Suite 100, Waltham, MA 02453, or such
other office as the Company shall notify the Holder of in writing, to purchase
from the Company at a price per share of $5.31 (the "Purchase Price"), 25,000
fully paid and nonassessable shares of Common Stock, $.01 par value per share,
of the Company (the "Common Stock"). Until such time as this Warrant is
exercised in full or expires, the Purchase Price and the securities issuable
upon exercise of this Warrant are subject to adjustment as hereinafter provided.

      3. Payment of Purchase Price. The Purchase Price may be paid (i) in cash
or by check, (ii) by the surrender by the Holder to the Company of any
promissory notes or other obligations issued by the Company, with all such notes
and obligations so surrendered being credited against the Purchase Price in an
amount equal to the principal amount thereof plus accrued interest to the date
of surrender, (iii) through delivery by the Holder to the Company of other
securities issued by the Company, with such securities being credited against
the Purchase Price in an amount equal to the fair market value thereof, as
determined in good faith by the Board of Directors of the Company (the "Board"),
or (iv) by any combination of the foregoing. The Board shall promptly respond in
writing to an inquiry by the Holder as to the fair market value of any
securities the Holder may wish to deliver to the Company pursuant to clause
(iii) above.

of this Warrant or any portion hereof by the surrender of this Warrant or such
portion to the Company, with the net issue election notice annexed hereto duly
executed, at the office of the Company. Thereupon, the Company

                                       21
<PAGE>

shall issue to the Holder such number of fully paid and nonassessable shares of
Common Stock as is computed using the following formula:

                                   X = Y (A-B)
                                       -------
                                          A

where

                        X =  the number of shares to be issued to the Holder
                  pursuant to this Section 4.

                        Y =  the number of shares covered by this Warrant in
                  respect of which the net issue election is made pursuant to
                  this Section 4.

                        A =  the fair market value of one share of Common Stock,
                  which shall be equal to the average closing price on the
                  Nasdaq National Market of the Common Stock over the ten (10)
                  day period prior to the date the net issue election is made
                  pursuant to this Section 4.

                        B =  the Purchase Price in effect under this Warrant at
                  the time the net issue election is made pursuant to this
                  Section 4.

The Board shall promptly respond in writing to an inquiry by the Holder as to
the fair market value of one share of Common Stock.

      5. Partial Exercise. This Warrant may be exercised in part, and the Holder
shall be entitled to receive a new warrant, which shall be dated as of the date
of this Warrant, covering the number of shares in respect of which this Warrant
shall not have been exercised.

      6. Issuance Date. The person or persons in whose name or names any
certificate representing shares of Common Stock is issued hereunder shall be
deemed to have become the holder of record of the shares represented thereby as
at the close of business on the date this Warrant is exercised with respect to
such shares, whether or not the transfer books of the Company shall be closed.

      7. Expiration Date. This Warrant shall expire at the close of business on
June 25, 2005, and shall be void thereafter.

      8. Reserved Shares; Valid Issuance. The Company covenants that it will at
all times from and after the date hereof reserve and keep available such number
of its authorized shares of Common Stock, free from all preemptive or similar
rights therein, as will be sufficient to permit the exercise of this Warrant in
full. The Company further covenants that such shares as may be issued pursuant
to the exercise of this Warrant will, upon issuance, be duly and validly issued,
fully paid and nonassessable and free from all taxes, liens and charges with
respect to the issuance thereof other than those caused or suffered by the
Holder hereof.

      9. Dividends. If after the Original Issue Date the Company shall subdivide
the Common Stock, by split-up or otherwise, or combine the Common Stock, or
issue additional shares of Common Stock in payment of a stock dividend on the
Common Stock, the number of shares issuable on the exercise of this Warrant
shall forthwith be proportionately increased in the

                                       22
<PAGE>

case of a subdivision or stock dividend, or proportionately decreased in the
case of a combination, and the Purchase Price shall forthwith be proportionately
decreased in the case of a subdivision or stock dividend, or proportionately
increased in the case of a combination.

      10. Mergers and Reclassifications. If after the Original Issue Date there
shall be any reclassification, capital reorganization or change of the Common
Stock (other than as a result of a subdivision, combination or stock dividend
provided for in Section 9 hereof), or any consolidation of the Company with, or
merger of the Company into, another corporation or other business organization
(other than a consolidation or merger in which the Company is the continuing
corporation and which does not result in any reclassification or change of the
outstanding Common Stock), or any sale or conveyance to another corporation or
other business organization of all or substantially all of the assets of the
Company, then, as a condition of such reclassification, reorganization, change,
consolidation, merger, sale or conveyance, lawful provisions shall be made, and
duly executed documents evidencing the same from the Company or its successor
shall be delivered to the Holder, so that the Holder shall thereafter have the
right to purchase, at a total price not to exceed that payable upon the exercise
of this Warrant in full, the kind and amount of shares of stock and other
securities and property receivable upon such reclassification, reorganization,
change, consolidation, merger, sale or conveyance by a holder of the number of
shares of Common Stock which might have been purchased by the Holder immediately
prior to such reclassification, reorganization, change, consolidation, merger,
sale or conveyance, and in any such case appropriate provisions shall be made
with respect to the rights and interest of the Holder to the end that the
provisions hereof (including without limitation, provisions for the adjustment
of the Purchase Price and the number of shares issuable hereunder) shall
thereafter be applicable in relation to any shares of stock or other securities
and property thereafter deliverable upon exercise hereof.

      11. Fractional Shares. In no event shall any fractional share of Common
Stock be issued upon any exercise of this Warrant. If, upon exercise of this
Warrant as an entirety, the Holder would, except as provided in this Section 11,
be entitled to receive a fractional share of Common Stock, then the Company
shall issue the next higher number of full shares of Common Stock, issuing a
full share with respect to such fractional share.

      12. Certificate of Adjustment. Whenever the Purchase Price is adjusted, as
herein provided, the Company shall promptly deliver to the Holder a certificate
of a firm of independent public accountants setting forth the Purchase Price
after such adjustment and setting forth a brief statement of the facts requiring
such adjustment.

      13. Notices of Record Date, Etc. In the event of:

            (a) any taking by the Company of a record of the holders of any
class of securities for the purpose of determining the holders thereof who are
entitled to receive any dividend or other distribution, or any right to
subscribe for, purchase or otherwise acquire any shares of stock of any class or
any other securities or property, or to receive any other right,

            (b) any reclassification of the capital stock of the Company,
capital reorganization of the Company, consolidation or merger involving the
Company, or sale or conveyance of all or substantially all of its assets, or

            (c) any voluntary or involuntary dissolution, liquidation or
winding-up of the Company,

                                       23
<PAGE>

then and in each such event the Company will mail or cause to be mailed to the
Holder a notice specifying (i) the date on which any such record is to be taken
for the purpose of such dividend, distribution or right, and stating the amount
and character of such dividend, distribution or right, or (ii) the date on which
any such reclassification, reorganization, consolidation, merger, sale or
conveyance, dissolution, liquidation or winding-up is to take place, and the
time, if any is to be fixed, as of which the holders of record in respect of
such event are to be determined. Such notice shall be mailed at least twenty
(20) days prior to the date specified in such notice on which any such action is
to be taken.

      14. Amendment. The terms of this Warrant may be amended, modified or
waived only with the written consent of the Company and the Holder hereof.
