Promissory Note in the amount of $8 million



 Exhibit 10.1 
 AMENDED AND RESTATED 
 PROMISSORY NOTE 
 December 29, 2006 
 FOR VALUE RECEIVED, GTC BIOTHERAPEUTICS,
INC., a Massachusetts corporation located at the address stated below (the “Borrower”), promises to pay to the order of GENERAL ELECTRIC CAPITAL CORPORATION or any subsequent holder hereof (each, a
“Lender”) at its office located at 83 Wooster Heights Road, Danbury, CT 06810 or at such other place as Lender or the holder hereof may designate, the principal sum of EIGHT MILLION AND 00/100 DOLLARS ($8,000,000.00), with
interest on the unpaid principal balance, from the date hereof through and including the dates of payment, at a fixed interest rate of ten and eighty hundredths percent (10.80%) per annum, to be paid in lawful money of the United States, in
fifty-nine (59) consecutive monthly installments of principal and interest commencing February 1, 2007, and continuing on the first day of each month thereafter, in the amount of $109,296.24, together with a final installment in the amount
of any and all remaining outstanding principal and interest (i.e. $5,159,298.88), and all other amounts outstanding, on January 1, 2012. Such installments have been calculated on the basis of a 360 day year of twelve 30-day months. Each payment
may, at the option of the Lender, be calculated and applied on an assumption that such payment would be made on its due date. 
 The
acceptance by Lender of any payment which is less than payment in full of all amounts due and owing at such time shall not constitute a waiver of Lender’s right to receive payment in full at such time or at any prior or subsequent time.

 The Borrower hereby expressly authorizes the Lender to insert the date value is actually given in the blank space on the face hereof and
on all related documents pertaining hereto. 
 This Amended and Restated Promissory Note (“Note”) is secured by an Amended
and Restated Master Security Agreement (as may be amended, restated, supplemented or modified from time to time, the “Master Security Agreement”) and an Amended and Restated Mortgage, Security Agreement and Fixture Filing (as may be
amended, restated, supplemented or modified from time to time), each from the Borrower to the Lender and dated as of the date hereof, together with any other security agreements, pledge agreements, mortgages, schedules or other collateral documents
delivered by the Borrower to the Lender from time to time to secure the obligations hereunder (as may be amended, restated, supplemented or modified from time to time, each a “Security Document”). 
 Time is of the essence hereof. If any installment or any other sum due under this Note or any Security Document is not received within ten (10) days
after its due date, the Borrower agrees to pay, in addition to the amount of each such installment or other sum, a late payment charge of five percent (5%) of the amount of said installment or other sum, but not exceeding any lawful maximum. If
(i) Borrower fails to make payment of any amount due hereunder within ten (10) days after the same becomes due and payable; or (ii) Borrower is in default under, or fails to perform under any term or condition contained in any
Security Document (other than those in Section 7(a)(x) and/or (xi) of the Master Security Agreement) (beyond any applicable grace period), then the entire principal sum remaining unpaid, together with all accrued interest thereon and any
other sum payable under this Note or any Security 







 
Document, at the election of Lender, shall immediately become due and payable, with interest thereon at the lesser of eighteen percent (18%) per annum
or the highest rate not prohibited by applicable law from the date of such accelerated maturity until paid (both before and after any judgment). If Borrower is in default under, or fails to perform under any term or condition under
Section 7(a)(x) or (xi) of the Master Security Agreement, then this Note and all Security Documents shall immediately become due and payable, without notice. 
 The Borrower may prepay in full, but not in part, its entire indebtedness hereunder plus an additional sum as a premium on any such prepayment equal to the following percentages of the then-outstanding
principal balance for the indicated period: 
 Prior to the first anniversary date of this Note: Not Allowed 
 Thereafter and prior to the second anniversary date of this Note: Five percent (5.0%) 
 Thereafter and prior to the third anniversary date of this Note: Four percent (4.0%) 
 and zero percent (0.0%) thereafter, 
 plus all other
sums due hereunder or under any Security Document; provided, however, that no premium shall apply to any mandatory prepayment of indebtedness required under the Master Security Agreement. 
 It is the intention of the parties hereto to comply with the applicable usury laws; accordingly, it is agreed that, notwithstanding any provision to the
contrary in this Note or any Security Document, in no event shall this Note or any Security Document require the payment or permit the collection of interest in excess of the maximum amount permitted by applicable law. If any such excess interest is
contracted for, charged or received under this Note or any Security Document, or if all of the principal balance shall be prepaid, so that under any of such circumstances the amount of interest contracted for, charged or received under this Note or
any Security Document on the principal balance shall exceed the maximum amount of interest permitted by applicable law, then in such event (a) the provisions of this paragraph shall govern and control, (b) neither Borrower nor any other
person or entity now or hereafter liable for the payment hereof shall be obligated to pay the amount of such interest to the extent that it is in excess of the maximum amount of interest permitted by applicable law, (c) any such excess which
may have been collected shall be refunded to Borrower, and (d) the effective rate of interest shall be automatically reduced to the maximum lawful contract rate allowed under applicable law as now or hereafter construed by the courts having
jurisdiction thereof. It is further agreed that without limitation of the foregoing, all calculations of the rate of interest contracted for, charged or received under this Note or any Security Document which are made for the purpose of determining
whether such rate exceeds the maximum lawful contract rate, shall be made, to the extent permitted by applicable law, by amortizing, prorating, allocating and spreading in equal parts during the period of the full stated term of the indebtedness
evidenced hereby, all interest at any time contracted for, charged or received from Borrower or otherwise by Lender

in connection with such indebtedness; provided, however, that if any applicable state law is amended or the law of the United States of America preempts any
applicable state law, so that it becomes lawful for the Lender to receive a greater interest per annum rate than is presently allowed, the Borrower agrees that, on the effective date of such amendment or preemption, as the case may be, the lawful
maximum hereunder shall be increased to the maximum interest per annum rate allowed by the amended state law or the law of the United States of America. 
 The Borrower and all sureties, endorsers, guarantors or any others (each such person, other than the Borrower, an “Obligor”) who may at any time become liable for the payment hereof jointly and
severally consent hereby to any and all extensions of time, renewals, waivers or modifications of, and all substitutions or releases of, security or of any party primarily or secondarily liable on this Note or any Security Document or any term and
provision of either, which may be made, granted or consented to by Lender, and agree that suit may be brought and maintained against any one or more of them, at the election of Lender without joinder of any other as a party thereto, and that Lender
shall not be required first to foreclose, proceed against, or exhaust any security hereof in order to enforce payment of this Note. The Borrower and each Obligor hereby waives presentment, demand for payment, notice of nonpayment, protest, notice of
protest, notice of dishonor, and all other notices in connection herewith, as well as filing of suit (if permitted by law) and diligence in collecting this Note or enforcing any of the security hereof, and agrees to pay (if permitted by law) all
expenses incurred in collection, including Lender’s actual attorneys’ fees incurred in collection. 
 THIS NOTE AND THE RIGHTS AND
OBLIGATIONS HEREUNDER SHALL IN ALL RESPECTS BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH, THE INTERNAL LAWS OF THE STATE OF CONNECTICUT (WITHOUT REGARD TO THE CONFLICT OF LAWS PRINCIPLES OF SUCH STATE). 
 THE BORROWER HEREBY UNCONDITIONALLY WAIVES ITS RIGHTS TO A JURY TRIAL OF ANY CLAIM OR CAUSE OF ACTION BASED UPON OR ARISING OUT OF, DIRECTLY OR
INDIRECTLY, THIS NOTE, ANY OF THE SECURITY DOCUMENTS OR OTHER RELATED DOCUMENTS, ANY DEALINGS BETWEEN BORROWER AND LENDER RELATING TO THE SUBJECT MATTER OF THIS TRANSACTION OR ANY RELATED TRANSACTIONS, AND/OR THE RELATIONSHIP THAT IS BEING
ESTABLISHED BETWEEN BORROWER AND LENDER. THE SCOPE OF THIS WAIVER IS INTENDED TO BE ALL ENCOMPASSING OF ANY AND ALL DISPUTES THAT MAY BE FILED IN ANY COURT (INCLUDING, WITHOUT LIMITATION, CONTRACT CLAIMS, TORT CLAIMS, BREACH OF DUTY CLAIMS, AND ALL
OTHER COMMON LAW AND STATUTORY CLAIMS.) THIS WAIVER IS IRREVOCABLE MEANING THAT IT MAY NOT BE MODIFIED EITHER ORALLY OR IN WRITING, AND THE WAIVER SHALL APPLY TO ANY SUBSEQUENT AMENDMENTS, RENEWALS, SUPPLEMENTS OR MODIFICATIONS TO THIS NOTE, ANY OF
THE SECURITY DOCUMENTS OR OTHER RELATED DOCUMENTS, OR TO ANY OTHER DOCUMENTS OR AGREEMENTS RELATING TO THIS TRANSACTION OR ANY RELATED TRANSACTION. IN THE EVENT OF LITIGATION, THIS NOTE MAY BE FILED AS A WRITTEN CONSENT TO A TRIAL BY THE COURT.
