Furthermore, concurrently with the execution of this Agreement, the Buyer, the Stockholders and Kef
Pharmaceuticals, Inc., a Delaware corporation (all of the issued and outstanding capital stock of
which is owned by the Stockholders) (“Kef”) are entering into a Stock Purchase Agreement
(the “Kef Stock Purchase Agreement”) pursuant to which Buyer shall have the right to
purchase all of the capital stock of Kef, as such agreement may be extended, amended or
supplemented.

	 	Deerfield Management Co. LP
	Ref:

	 	Series C

     2.3 Consideration for Stock Purchase.

     (a) In the event the Buyer exercises the Stock Purchase Right, the aggregate consideration to
be paid by the Buyer to the Stockholders for the Shares shall be equal to the Stock Purchase Base
Price plus (i) if the IND is owned by the Corporation as of the Closing Date, an amount
equal to (A) Eight Million Four Hundred Thousand Dollars ($8,400,000), plus (B) the amount
of Cash held by the Corporation on the Closing Date, minus (C) the amount of accrued,
unpaid Taxes owed by the Corporation, minus (D) all accrued payment obligations then owed
under Contracts, other than the Related Agreements, entered into by the Corporation, and
minus (E) the amount of any Stock Purchase Period Extension Payments made by Buyer, or
(ii) if the IND is not owned by the Corporation as of the Closing Date, an amount equal to (v) Six
Million Three Hundred Thousand Dollars ($6,300,000), plus (w) the amount of Cash held by
the Corporation on the Closing Date, minus (x) the amount of accrued, unpaid Taxes owed by
the Corporation, minus (y) all accrued payment obligations then owed under Contracts, other
than the Related Agreements, entered into by the Corporation, and minus (z) the amount of
any Stock Purchase Period Extension Payments made by Buyer (as applicable under clause (i) or (ii),
the “Purchase Price”). The Stockholder Representative shall provide written notice (the
“Adjustment Notice”) of the amount of any adjustments made pursuant to clauses (B), (C) and
(D) or clauses (w), (x) and (y), as appropriate, no later than five (5) Business Days prior to the

Shares held by each Stockholder.

     (b) The Buyer shall be entitled to deduct and withhold from the consideration otherwise
payable to any Person pursuant to this Agreement such amounts as it is required to deduct and
withhold with respect to the making of such payment under any provision of U.S. federal, state or
local tax Law. If the Buyer so deducts and withholds amounts, such amounts shall be treated for
all purposes of this Agreement as having been paid to the Stockholder in

3

 

respect of which the Buyer
made such deduction and withholding. The Parties shall reasonably cooperate to minimize such
withholding amounts.

     2.4 Term and Extension. The Buyer shall have the authority to exercise the Stock
Purchase Right solely according to the following timetable:

     (a) The Stock Purchase Right shall terminate at 5:00 p.m. on June 30, 2008 (the “Initial

Corporation at the time of such payment or (ii) Nine Hundred Fifty Thousand Dollars ($950,000) if
the IND is not owned by the Corporation at the time of such payment.

Extended Termination Time”), by delivering to the Corporation prior to the First Extended
Termination Time, a written notice of extension along with a Stock Purchase Period Extension
Payment in an amount equal to (i) Four Million Two Hundred Thousand Dollars ($4,200,000) if the IND

Thousand Dollars ($3,150,000) if the IND is not owned by the Corporation at the time of such
payment.

forth in Sections 2.4(a) and 2.4(b), the Stock Purchase Right shall terminate on the Second
Extended Termination Time; provided, that Buyer shall have the option to further extend the
Stock Purchase Right beyond the Second Extended Termination Time to 5:00 p.m. on November 1, 2012

Two Hundred Thousand Dollars ($2,200,000) if the IND is not owned by the Corporation at the time of
such payment.

     (d) Notwithstanding Sections 2.4(a)-(c), no Stock Purchase Period Extension Payment shall
extend the Stock Purchase Right unless an extension payment is simultaneously
made pursuant to Section 2.4(a) and Section 2.4(b), as applicable, of the Kef Stock Purchase
Agreement.

     (e) At any time prior to the expiration of the Stock Purchase Period, the Buyer may exercise
the Stock Purchase Right by delivery to the Stockholder Representative of a written notice (the
“Stock Purchase Notice”) substantially in the form of Exhibit C. The Stock Purchase Notice
shall constitute a binding obligation of the Buyer to purchase, and the Stockholders to sell, all
of the Shares pursuant to the terms and conditions of this Agreement. The Stock

4

 

Purchase Notice
may be delivered on any Business Day during the Stock Purchase Period and shall specify a Closing
Date for the Stock Purchase, which shall be a Business Day not earlier than ten (10), nor later
than thirty (30), days after the date of the Stock Purchase Notice (the “Target Closing

REPRESENTATIONS RELATING TO THE CORPORATION

     The Stockholders and the Corporation jointly and severally represent to the Buyer that:

power and authority to own, lease and use the properties and assets that it owns, leases and
uses and to conduct its business as presently conducted.

the Shares. All of the Shares have been duly authorized and validly issued and are fully paid and
nonassessable and free of preemptive and similar rights. All of the Shares are owned by the

shares of capital stock, debt securities or voting securities or ownership interests in the
Corporation; (iii) subscriptions, calls, contracts, commitments, understandings, restrictions,
arrangements, rights, warrants, options, or other rights that grant or may grant the right to
acquire from the Corporation, or obligations of the Corporation to issue any capital stock, debt
securities, voting securities or other ownership interests in, or any securities convertible into
or exchangeable or exercisable for any capital stock, voting securities, debt securities or
ownership interests in, the Corporation, or obligations of the Corporation to grant, extend or
enter into any such agreement or commitment; or (iv) obligations of the Corporation to repurchase,
redeem or otherwise acquire any outstanding securities of the Corporation, or to vote or to dispose

Corporation

6

 

have been offered and issued in compliance with all applicable federal and state
securities laws, including “blue sky” laws.

     3.3 There are no agreements, arrangements, proxies or understandings that restrict or
otherwise affect the transfer of any of the Shares except as set forth in this Agreement.

     3.4 The Corporation has all requisite corporate power and authority to execute, deliver and
perform its obligations under this Agreement, and the execution and delivery of this Agreement and
the performance of all of its obligations hereunder have been duly authorized by the Corporation
and the Stockholders. This Agreement has been duly executed and delivered by the Corporation and
constitutes the legal, valid and binding obligation of the Corporation, enforceable against the
Corporation in accordance with its terms, except as enforceability may be limited or affected by
applicable bankruptcy, insolvency, moratorium, reorganization or other laws of general application
relating to or affecting creditors’ rights generally.

     3.5 The signing, delivery and performance of this Agreement by the Corporation is not
prohibited or limited by, and will not result in the breach of or a default under, any provision of
the certificate of incorporation, bylaws or other formation documents of the Corporation, or of any
material agreement or instrument binding on the Corporation, or of any applicable law, Order, writ,
injunction or decree of any Governmental Authority, except for such prohibition, limitation or
default as would not prevent consummation by the Corporation of the transactions contemplated
hereby. The execution, delivery and performance of this Agreement by the Corporation, and the
Corporation’s compliance with the terms and provisions hereof, do not and will not conflict with or
result in a breach of any of the terms and provisions of or constitute a default, with or without
the passage of time and the giving of notice, under any Contract or other instrument or obligation
binding or affecting the Corporation or the Corporation’s property, including the Purchased Assets.

     3.6 There is no action, suit, litigation, Proceeding, claim, governmental investigation or
administrative action pending or, to the Stockholders’ Knowledge, threatened, directly or
indirectly involving the Corporation or the transactions contemplated hereby or the Corporation’s
ability to perform its obligations hereunder. The Corporation is not a party or subject to or in
default under any judgment, Order, injunction or decree of any Governmental Authority or
arbitration tribunal applicable to the Corporation or its property.

     3.7 No insolvency Proceeding of any character, including, without limitation, bankruptcy,
receivership, reorganization, composition or arrangement with creditors, voluntary or involuntary,
has been commenced by or against the Corporation or any of its assets or properties, nor, to the
Stockholders’ Knowledge, is any such Proceeding threatened. Neither the Stockholders nor the
Corporation contemplates, nor has the Corporation or any Stockholder taken any action in
contemplation of, the institution of any such insolvency Proceedings.

     3.8 No broker, investment banker, agent, finder or other intermediary acting on behalf of the
Corporation or under the authority of the Corporation is or will be entitled to any broker’s or
finder’s fee or any other commission or similar fee directly or indirectly in connection with any
of the transactions contemplated hereby.

7

 

     3.9 The Corporation’s assets, other than Cash, consist solely of the Purchased Assets. The
Corporation has no Liabilities or obligations of any nature, whether or not accrued, absolute,
contingent, unliquidated or otherwise, whether due or to become due and whether or not required to
be closed, other than those Liabilities and obligations created by this Agreement and the Related
Agreements. The Corporation does not own any interest in any other corporation, partnership,
association, joint venture or other entity and, thus, has no subsidiaries.

     3.10 There are no Encumbrances upon any of the Shares other than those created by this
Agreement.

     3.11 None of the Shares has been issued in violation of any Legal Requirement, the certificate
of incorporation or bylaws of the Corporation, or any Contract to which the Corporation may be
subject, bound or a party or in violation of any preemptive, subscription or similar rights.

     3.12 Except as set forth on Schedule 3.12, from the date of the Corporation’s incorporation,
except as contemplated by this Agreement, there has not been any:

     (a) change in the Corporation’s authorized or issued capital stock;

     (b) disposition by the Corporation of any of the Purchased Assets; or

     (c) agreement, whether oral or written, by the Corporation to do any of the foregoing.

     3.13 The Corporation is in compliance with all applicable Legal Requirements, except (i) Legal
Requirements constituting obligations of the Buyer that have been assumed by the Corporation or

regarding any violation of, or failure to comply with, any Legal Requirement.

     3.15 The Corporation was formed solely for the purpose of engaging in the transactions
contemplated by this Agreement and the Related Agreements. The Corporation has not owned, operated
or conducted and, other than its acquisition of the Purchased Assets pursuant to the Lex Asset
Purchase Agreement, will not own, operate or conduct any assets, businesses or activities other
than in connection with its organization, the negotiation and execution of this Agreement and the
Related Agreements and the consummation of the transactions contemplated hereby and thereby.

     3.16 No Governmental Authorization is required by the Corporation in connection with the
execution or delivery by the Corporation of this Agreement or the performance by the Corporation of
the Corporation’s obligations under this Agreement, except for any Governmental Authorizations that
result from the specific legal or regulatory status of the Buyer or as a result of any other facts
that specifically relate to the business or activities in which the Buyer is engaged. Neither the
execution and delivery of this Agreement by the Corporation nor the performance of the
Corporation’s obligations hereunder or thereunder shall (with or without notice or lapse of time)
(i) result in the creation of any Encumbrance upon the Shares or (ii)

8

 

conflict with or violate any
Legal Requirement applicable to the Corporation, except for any Legal Requirements that result from
the specific legal or regulatory status of the Buyer or as a result of any other facts that

     8.4 Procedure for Indemnification – Third-Party Claims.

     (a) If any Person shall claim indemnification hereunder arising from any claim or demand of a
third party, the party seeking indemnification (the “Indemnified Party”) shall notify the
party from whom indemnification is sought (the “Indemnifying Party”) in writing of the
basis

17

 

for such claim or demand and such notice shall set forth the nature of the claim or demand in
reasonable detail. The failure of the Indemnified Party to so notify the Indemnifying Party shall
not relieve the Indemnifying Party of any indemnification obligation hereunder except to the extent
that the defense of such claim or demand is prejudiced by the failure to give such notice.

     (b) If any Proceeding is brought by a third party against an Indemnified Party and the
Indemnified Party gives notice to the Indemnifying Party pursuant to Section 8.4(a), the
Indemnifying Party may assume the settlement or defense of such Proceeding. The Indemnified Party
shall, in its sole discretion, have the right to employ separate counsel (who may be selected by
the Indemnified Party in its sole discretion) in any such Proceeding and to participate in the
defense thereof, and the fees and expenses of such counsel shall be paid by such Indemnified Party.
If the Indemnified Party assumes the defense of such Proceeding because of the failure of the
Indemnifying Party to conduct such defense in good faith, the fees and expenses of such counsel
shall be paid by the Indemnifying Party. The Indemnified Party shall cooperate fully with the
Indemnifying Party and its counsel in the defense or settlement of such Proceeding. If the
Indemnifying Party assumes the defense of a Proceeding, no compromise or settlement of such claims
may be effected by the Indemnifying Party without the Indemnified Party’s consent unless (i) there
is no finding or admission of any violation of Legal Requirements or the rights of any Person by
the Indemnified Party and no Material Adverse Effect on the Indemnified Party with respect to any
other claims that may be made against it, and (ii) the sole relief provided is monetary damages
that are paid in full by the Indemnifying Party.

     (c) If (i) notice is given to the Indemnifying Party of the commencement of any third-party
Proceeding and the Indemnifying Party does not, within ten (10) days after the Indemnified Party’s
notice is given, give notice to the Indemnified Party of its election to assume the defense of such
Proceeding, or (ii) having assumed the defense of such Proceeding, the Indemnifying Party fails to
conduct such defense in good faith, then the Indemnified Party shall (upon notice to the
Indemnifying Party) have the right to undertake the defense, compromise or settlement of such
claim; provided that no compromise or settlement of such claim may be affected by the
Indemnified Party without the Indemnifying Party’s consent, if (A) the Indemnifying Party will be
liable for any amounts to be paid to compromise or settle the claim, (B) there is a finding or
admission of any violation by the Indemnifying Party of any Legal Requirement or the rights of any
Person, or (C) the compromise or settlement would have a Material Adverse Effect on the
Indemnifying Party with respect to any other claims that may be made against it. The Indemnifying
Party shall reimburse the Indemnified Party for the costs and expenses of
defending against the third-party claim (including reasonable attorneys’ fees and expenses)
and the Indemnifying Party shall remain responsible for any Damages arising from or related to such
third-party claim to the extent provided in this Article VIII. The Indemnifying Party may elect to
participate in such Proceedings, negotiations or defense at any time at its own expense.

     8.5 Limitation on Damages.

     (a) Notwithstanding anything set forth herein to the contrary, all Damages recoverable by an
Indemnified Party shall be net of any proceeds such Indemnified Party recovers, or is entitled to
recover, under any applicable insurance coverage and any amounts such Indemnified Party recovers,
or is entitled to recover, from third parties, except to the extent such recoveries have or are
reasonably expected to result in future or retroactive premium

18

 

increases (any such net recovered
amount, an “Insurance Recovery”). Accordingly, the amount that an Indemnifying Party is
required to pay to any Indemnified Party will be reduced by any Insurance Recovery;
provided, however, that any Damages described in Section 8.2 or 8.3 that are
incurred by an Indemnified Party shall be paid or, in the case of amounts that may be insured,
advanced, promptly by the Indemnifying Party and shall not be delayed pending any determination as
to the availability of any Insurance Recovery. If an Indemnified Party receives a payment required
to be made under this Article VIII from an Indemnifying Party in respect of any Losses and
subsequently receives any Insurance Recovery, then the Indemnified Party shall promptly pay such
Insurance Recovery to the Indemnifying Party.

     (b) Upon any payment of Damages to an Indemnified Party, the Indemnifying Party shall be
subrogated to all rights of the Indemnified Party with respect to the Damages to which such
indemnification relates to the extent of the amount of such payment.

     (c) The Indemnified Party shall have no right to recover consequential, punitive or multiplied
damages except to the extent the Indemnified Party is liable to a third party for such damages.

     8.6 Tax Treatment of Indemnity. Notwithstanding anything to the contrary in
Article VIII, any Tax or other amount for which indemnification is provided under this Agreement
shall be treated as an adjustment to the Purchase Price.

incurred to replenish the Consigned Merchandise pursuant to this Section 4.

     5. Risk of Loss and Insurance. Consignee will bear all risk of loss or damage to
Consigned Merchandise and will maintain (i) all-risk property insurance for the full replacement
value on all Consigned Merchandise and (ii) general liability insurance under customary
pharmaceutical industry forms and endorsements, providing product liability and contractual
liability coverage, with per occurrence limits of not less than $10,000,000, which limits may be
achieved through a combination of underlying and excess policies. The insurance policies described
in the preceding sentence shall be endorsed to (A) name Consignor as an additional insured and loss
payee, as applicable and (B) be primary and non-contributory to any insurance otherwise available
to Consignor. Consignee will cause the insurer to provide Consignor with a certificate of
insurance evidencing the existence of such insurance, including its primary and non-contributory
nature, upon the execution of this Agreement and at such times as Consignor may request thereafter.
Such certificate of insurance shall provide that the insurer will notify Consignor not less than
thirty (30) days prior to any expiration, non-renewal, cancellation, reduction in limits or
exhaustion of limits of such insurance. Consignee will be responsible for any deductible or
self-insured amounts under any such insurance.

     6. Terms of Consignment Sales. Subject to the terms hereof, all Consignment Sales
shall be made in the ordinary course of Consignee’s business.

     7. Product Warranties. CONSIGNEE HEREBY ACCEPTS ALL CONSIGNED MERCHANDISE ON AN “AS
IS” BASIS WITHOUT WARRANTIES OF ANY SORT, INCLUDING EXPRESS OR IMPLIED WARRANTIES OF
MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE. Consignee shall be responsible for all
products warranties made in connection with Consignment Sales and shall indemnify and hold harmless
Consignor from and against all warranty claims of any sort arising out of Consignment Sales, other
than claims arising out of Consignor’s gross negligence or willful misconduct.

     8. Consignment Payment. In consideration of the Consignment of Consigned Merchandise
pursuant to this Agreement, Consignee shall pay Consignor payments (each such payment a
“Consignment Payment”) as follows:

4

 

     (a) Initial Period Payment. During the Initial Period, the Consignment Payment shall
be equal to eleven percent (11%) of Consignee’s Net Sales of Consigned Merchandise, plus such
additional amount, if any, as may be necessary for Consignee to pay the Minimum Consignment
Payment.

     (b) Extended Period Payment. During the Extended Period, the Consignment Payment
shall be equal to six percent (6%) of Consignee’s Net Sales of Consigned Merchandise, plus such
additional amount, if any, as may be necessary for Consignee to pay the Minimum Consignment
Payment.

     (c) Minimum Consignment Payment. Regardless of the amount of Net Sales, the Minimum
Consignment Payment during any calendar quarter shall be Four Hundred Thousand Dollars ($400,000)
(the “Minimum Consignment Payment”); provided, that any payment by Consignee to Lex
during any calendar quarter pursuant to the Registration License shall be included for purposes of
determining whether Consignee has paid the Minimum Consignment Payment for such calendar quarter.
The Minimum Consignment Payment shall be pro-rated during the first and last calendar quarters of
the Term to reflect the portion of such calendar quarters during which this Agreement is in effect.

     (d) Quarterly Payment. Within thirty (30) days after the end of each calendar quarter
any part of which is during the Term, Consignee shall deliver to Consignor (i) a written statement
showing all Net Sales during such calendar quarter and (ii) the greater of (A) the Consignment
Payment due upon such Net Sales and (B) the Minimum Consignment Payment. All payments shall be
made by wire transfer of immediately available funds to an account designated by Consignor at least
two (2) Business Days in advance.

     9. Access by Consignor.

     (a) Inspection. Consignee will permit Consignor, its officers, agents and accountants
access to Consignee’s facilities and Consignee Locations during customary business hours for the
purpose of inspecting and otherwise examining the Consigned Merchandise and auditing the books and
records of Consignee to the extent such books and records reflect sales of Consigned Merchandise.
Consignor will give Consignee not less than three (3) Business Days’ prior notice, which notice may
be given orally, electronically, in writing or by any other reasonable and verifiable means of
communication, prior to inspection. Consignor will conduct any such inspection or audit in a
manner that does not unreasonably interfere with the ordinary conduct of Consignee’s business and
will permit Consignee to observe any inspection of the Consigned Merchandise conducted by
Consignor.

     (b) Audit. Upon not less than seven (7) days written notice, Consignor shall have the
right to audit the books and records of Consignee relating to sales of Consigned Merchandise for
the purpose of determining the correctness of Consignee’s computation and payment of the
Consignment Payment. Such audit may not be conducted more than once in any six-month period and
shall be conducted during normal business hours. Consignor may engage an accounting firm at its
cost to perform or assist in such audit. Consignee shall provide Consignor, its officers, agents
and accountants with access to all pertinent books and records and shall reasonably cooperate with
Consignor’s efforts to conduct such audits.

     10. Termination.

     (a) Termination of Stock Purchase Right. This Agreement shall terminate without
further action by either party hereto upon the termination or expiration of the Stock Purchase

Sublicense (other than termination thereof upon the closing of the purchase of capital stock

Sublicense (other than termination thereof upon the closing of the purchase of capital stock

of any material provision of this Agreement that is not cured within thirty (30) days after
Consignee’s giving Consignor written notice thereof.

     (iii) Upon termination of this Agreement pursuant to this Section 10(b), all amounts
due and payable by Consignee shall immediately become due and payable without further notice
or demand.

     (c) Termination for Non-Payment of Consignment Payment: Without otherwise limiting
Section 10, Consignor shall have the right to terminate the Agreement if Consignee shall (i) fail
to pay any part of the Consignment Payment when due and shall fail to cure such non-payment within
(A) fifteen (15) days after receiving written notice if Consignee has not exercised its Stock
Purchase Right or (B) sixty (60) days of receiving written notice of such non-payment from
Consignor if Consignee has exercised its Stock Purchase Right, unless the amount required to be
paid is the subject of a good faith dispute between the Parties and undisputed amounts, as of the
last due date prior to notice being given, have been paid.

     (d) Return of Consigned Merchandise. Upon the termination of this Agreement,
Consignee shall (i) (A) at Consignee’s expense immediately deliver all Consigned Merchandise to a

     (e) No Release of Obligations. Termination of this Agreement shall not release either
party hereto from any obligation incurred prior to the date of termination or arising out of
termination. The remedies expressly set forth herein are in addition to any other remedies that
may otherwise be available to Consignor under this Agreement, the Uniform Commercial Code or other
applicable law and do not serve to waive or modify Consignor’s rights with respect thereto.

     11. Amendment; Waiver. This Agreement, including the Schedules hereto, may be
amended, modified or supplemented only by an agreement in writing signed by the Parties. No course
of dealing between the Parties or failure by a Party to exercise any right or remedy hereunder
shall constitute an amendment to this Agreement or a waiver of any other right or remedy or the
later exercise of any right or remedy.

     12. Force Majeure. No Party shall be responsible to any other Party for any failure
or delay in performing any of its obligations under this Agreement or for other nonperformance
hereof if such delay or nonperformance is caused by fire, flood, accident, act of God or of the
government or any country or of any state or local government, or of the public enemy of either, or
by cause unavoidable or beyond the control of such Party. In such event, the Party affected will
use reasonable commercial efforts to resume performance of its obligations.

be construed as if such invalid, illegal or unenforceable provision had never been contained
herein, unless the invalidity of any such provision substantially deprives either Party of the
practical benefits intended to be conferred by this Agreement. Notwithstanding the foregoing, any
provision of this Agreement held invalid, illegal or unenforceable only in part or degree shall
remain in full force and effect to the extent not held invalid or unenforceable, and the
determination that any provision of this Agreement is invalid, illegal or unenforceable as applied
to particular circumstances shall not affect the application of such provision to circumstances
other than those as to which it is held invalid, illegal or unenforceable.

an equal opportunity to negotiate the terms and conditions of this Agreement and that any rule of

similar rule operating against the drafter of an agreement shall not be applicable to the
construction or interpretation of this Agreement.

     19. Related Agreement. This Agreement, including the Purchase Agreement and Related
Agreements, appendices, schedules and exhibits thereto, are intended to be construed as parts of a
group of related transactions and shall be construed accordingly.
