Employment Agreement

This Employment Agreement ("Agreement") is dated March 17, 2003 and effective as of the Employment Commencement Date set forth in Section 1 below ("Effective Date") by and between Schrödinger, Inc., a Delaware corporation ("Company"), and Jenny Herman ("Employee").

WHEREAS, the Company is currently in the business of (i) designing, developing, distributing, selling, licensing, leasing and servicing computer software programs for use principally in the fields of quantum chemistry, computational chemistry, molecular mechanics/dynamics, protein structure prediction, computational ligand docking, and other science and technology fields, and (ii) providing services and performing research involving the use of such software in connection with various biological, chemical, and materials science applications, and may engage in other activities in the future (such current and future activities collectively, the "Company's Business");

WHEREAS, Employee is engaged by the Company to perform certain services for Company and/or one or more subsidiaries of and/or other Affiliates (as hereinafter defined) of the Company (collectively, the Company, its subsidiaries, and its other Affiliates shall be referred to as the "Schrödinger Companies");

WHEREAS, in connection with such duties, Employee may have access to certain confidential information and trade secrets of one or more Schrödinger Companies and/or, as the case may be, the D. E. Shaw Group (as hereinafter defined), and may in the course of Employee's employment with the Company discover or conceive one or more inventions; and

WHEREAS, the Company and Employee desire to define the rights and obligations between them with respect to the subject matter hereto.

NOW THEREFORE, in consideration of the promises and covenants set forth below, the parties agree as follows:

1.Employment. Employment commenced on May 1, 2002 ("Employment Commencement Date") and may be terminated by either party at any time, for any reason, upon 30 days' notice (the "Notice Period"), which notice may be given either verbally or in writing. Notwithstanding the foregoing, the Company may elect to terminate employment immediately upon notice, except that in this event, the compensation and benefits set forth in Section 2 shall be continued for the duration of the Notice Period, provided that the foregoing shall not modify the terms and conditions of any Company stock option plan. The Employee acknowledges and agrees that the Employee is an employee at will, and that just as the Employee is free to resign at any time, the Company has the right to terminate the employment relationship at any time for any lawful reason. The Employee acknowledges and agrees that no representative of the Company may verbally change the at will employment relationship between the Employee and the Company. References to time periods in this Agreement shall not be construed or interpreted as promising or guaranteeing employment for any specific duration or until any specific date.

b.Base Salary After the Compensation Period. As of the end of the Compensation Period, the Employee's base salary may be increased or decreased, or the manner in which the Employee is compensated may be changed, in the sole discretion of the Company. Any such change in compensation shall be deemed to modify only this Section 2 of this Agreement, and all other provisions of this Agreement shall remain in effect following such change in compensation. In the absence of any such change, the Employee's base salary shall remain the same as it was during the Compensation Period.

c.Standard Company Benefits. In addition to the compensation outlined elsewhere in this Section 2, the Company shall provide to the Employee all of the benefits included in the Company's standard benefit package, which currently include medical (hospitalization and major medical), dental, disability, life, and accidental death and dismemberment insurance. Most of the cost of such benefits shall be borne by the Company. However, in the case of coverage for the Employee himself or for one or more of Employee's beneficiaries, the Employee makes a pre-tax contribution to the cost of the medical and dental insurance. Individual and dependent medical and dental insurance contribution amounts are determined on a set scale, based on the actual cost of the insurance. For additional levels of life insurance beyond the Company's basic benefit, the required contribution will be borne by the Employee by means of a voluntary salary reduction in the amount of the contribution implemented by Company at the request of the Employee.

The standard benefit package also currently includes a flexible spending account plan, a transit reimbursement plan, and a 401(k) retirement plan, available to all qualified full- time employees. Enrollment in the 401(k) retirement plan will be allowed for all employees who work 25 or more hours per week at any time. Company does not contribute to the flexible spending account plan, the transit reimbursement plan, or the 401(k) retirement plan, but the Employee may contribute pre-tax dollars. The Employee agrees that the composition, providers, and all other aspects of Company's standard benefit package may be changed from time to time in the sole discretion of the Company.

d.Stock Option Plan. The Employee may be eligible to receive stock options under the Company's standard stock option plan, which may be modified by the Company at any time, in the sole discretion of the Company.

e.Exclusive Compensation. The compensation and benefits described in this Section 2 shall be the exclusive compensation due to the Employee from the Company or any of its Affiliates during or on account of the services of the Employee. If directed by the Company, the Employee shall provide the services described in this Agreement to one or more Affiliates of the Company without additional compensation.

3.Duties. The Employee will devote Employee's full time, skill, efforts, and attention to the Company's Business, and shall perform such duties at such locations and on behalf of such Schrödinger Companies as may be assigned by the officers or directors of the Company from time to time. The Employee agrees to abide by all applicable laws and regulations in connection with the Employee's employment.

4.Confidentiality.

4.1 Definition. For the purposes of this agreement, "Confidential Information" shall mean any information, including but not limited to:

a.any inventions, trade secrets, discoveries, know-how, research, improvements, concepts, ideas, and principles whether or not patentable or copyrightable (including without limitation processes, methods, formulas, techniques, devices, designs, software, computer processing systems and techniques, algorithms, flow charts, specifications, computer graphics, data, apparatus, products, and molecular structures), relating to past, present, or contemplated future activities of one or more Schrödinger Companies;

b.price lists, customer lists, supplier lists, business plans, marketing plans, financial and payroll information, as well as any information contained in documents marked "Confidential," which relates to the business of one or more Schrödinger Companies and which Employee may prepare, use, or have access to during the term of the employment;

d.the results of any marketing, advertising, joint venture, business, financial, or other analysis conducted by (or on behalf of) one or more Schrödinger Companies for the internal use of one or more Schrödinger Companies or for other non-public use (and not approved by Company for general dissemination to the public);

e.any information that would typically be included in Company's income statements, including but not limited to the amount of Company's revenues, expenses, or net income;

f.any plans for the business of one or more Schrödinger Companies (whether or not such plans have been reduced to writing), financial information concerning such plans (including without limitation projected revenues, projected expenses, and projected net income), descriptions of such business and technical aspects of or relating to the operation of such business, and products and services that one or more Schrödinger Companies is considering exploring, developing, and/or researching;

g.any other information gained in the course of the Employee's employment with the Company that could reasonably be expected to prove deleterious to any Schrödinger Company or to any entity within the D. E. Shaw Group if disclosed to third parties,

including without limitation any information that could reasonably be expected to aid a competitor of any Schrödinger Company or the D. E. Shaw Group in making inferences regarding the nature of the Schrödinger Companies' or D. E. Shaw Group's activities, where such inferences could reasonably be expected to adversely affect the competitive position of any Schrödinger Company or the D. E. Shaw Group relative to that of such a competitor;

h.any other information gained in the course of or incident to the Employee's employment that a Schrödinger Company has received from a third party and is required to hold confidential; and

"Confidential Information" shall not include information which Employee can show (x) is or becomes part of the public domain through no fault of Employee; (y) is already known to Employee and has been identified in writing prior to the date of this Agreement; or (z) is subsequently received by Employee from a third party who has no obligation of confidentiality to one or more Schrödinger Companies or the D. E. Shaw Group.

4.2 Acknowledgment of Proprietary Interest. Employee acknowledges that the Confidential Information described above is proprietary to one or more Schrödinger Companies or, as the case may be, the D. E. Shaw Group and contains valuable trade secrets of one or more Schrödinger Companies or, as the case may be, the D. E. Shaw Group.

4.3 Covenant Not to Disclose Confidential Information. During the term of Employee's employment and at any time thereafter, Employee agrees not to disclose or use, directly or indirectly, except in pursuit of the Employee's duties to one or more Schrödinger Companies, any Confidential Information, unless Employee shall first secure written consent of the Company to such disclosure or use, or unless Employee is compelled to do so by court order or applicable law and Employee provides prior written notice of such disclosure to the Company. Without limiting the foregoing, Employee agrees not to publish, or cause or authorize to be published, any document containing Confidential Information or related to the Company's Business, without the Company's prior written approval (which may be granted or withheld in Company's sole discretion).

4.4 Acknowledgment of Reasonableness. The Company and Employee hereby acknowledge that (a) the Company's market for its products is unlimited geographically and the foregoing non-disclosure requirements shall apply to Employee on a worldwide basis, and (b) the geographical and durational limitations imposed with respect to the Confidential Information are fair and reasonable, and are reasonably necessary to protect the Confidential Information of the Company. In the event that any provision relating to the geographical, durational, or other restrictions on Employee are declared by a court of competent jurisdiction to exceed the maximum time period, area, or other measure such court deems reasonable and enforceable, said time period, area, or other measure shall be deemed to become and thereafter be the maximum amount which such court deems reasonable and enforceable.

Employee will promptly return to the Company all written materials, computer software programs, or other materials containing Confidential Information and all other materials or documents, including without limitation mailing lists, rolodexes, computer print-outs, and computer disks and tapes, belonging to one or more Schrödinger Companies which contain information pertaining to the Company's Business, methods, clients, potential clients, customers, potential customers, funding providers, potential funding providers, or employees, unless the Company consents in writing to the Employee's retention thereof.

4.6 Remedies upon Breach. Employee recognizes that the disclosure or use of any Confidential Information would cause the Company irreparable injury, which may not be adequately compensated by damages. Accordingly, in the event Employee breaches or threatens to breach any provision of this Agreement, the Company or, as the case may be, the D. E. Shaw Group, shall be entitled to an injunction restraining Employee from disclosing or using, in whole or in part, any Confidential Information, or from rendering any services to any person, firm, corporation, or other entity to whom such Confidential Information, in whole or in part, has been, is threatened to be, or would necessarily be disclosed or used by Employee. Nothing herein shall be construed as prohibiting the Company or, as the case may be, the D. E. Shaw Group, from pursuing any other remedies available to it for such breach or threatened breach, including the recovery of damages from Employee or any third party. The right of the Company and/or the D. E. Shaw Group to seek equitable relief under this Agreement shall be in addition to (and not in derogation of) the requirement imposed on each party hereto to arbitrate disputes as provided in Section 7.1 below.

4.7 Ownership of Confidential Information. All Confidential Information and all right, title and interest in and to patents, patent rights, copyright rights, mask work rights, trade secret rights, and all other intellectual property and proprietary rights anywhere in the world (collectively, "Rights") in connection therewith shall be the sole property of the relevant Schrödinger Company, which, if other than Schrödinger, Inc., shall be a third-party beneficiary of this Agreement. Employee hereby assigns to the Company any Rights Employee may have or acquire in such Confidential Information.

4.8 Confidential Information of Others. The Employee agrees not to disclose to any Schrödinger Company any confidential or proprietary information belonging to any of the Employee's previous employers, or belonging to any other party, without first securing the written permission of such previous employers or other parties. In addition, Employee agrees that Employee will not bring with Employee any confidential or proprietary information belonging to any of Employee's previous employers or to any other person, that Employee will refrain from using while employed by the Company any such confidential or proprietary information, and that Employee will comply with the non-disclosure, non-compete, and other provisions of Employee's agreements with Employee's prior employers and with other persons. The Employee agrees to indemnify each Schrödinger Company for any expense, claim, or damages (including without limitation attorneys' fees, costs of investigation, and costs of collection) suffered by such entity relating to a breach of the terms of this paragraph by the Employee.

5.Inventions.

5.1 Proprietary Rights; Assignment. All right, title and interest, and all proprietary claims to all data and other information, patentable inventions, non-patentable processes or know-how, designs, and/or ideas for formulae, including but not limited to methodology,

computer programs, systems, materials and manuals conceived, developed, made or produced by Employee (alone or in conjunction with others) (a) in the course of Employee's employment with the Company, or (b) with the time, private or proprietary information, or facilities of one or more Schrödinger Companies (collectively, the materials described in Subsections 5.l(a) and 5.l(b) heretofore shall be referred to as the "Developments"), including without limitation all rights under applicable copyright, patent or trade secret laws, shall reside with Company (or such Schrödinger Company designated by Company) and, where applicable, shall be considered "works made for hire"; provided, however, that such ownership may be subject to the rights, if any, of the United States government and agencies thereof arising from Federal grants to the Company. Employee hereby assigns to the Company (or such Schrödinger Company designated by the Company) all right, title, and interest Employee has or may have in the Developments. Employee agrees that neither Employee nor Employee's successors or assigns shall have any rights in the Developments.

5.2 Disclosure: Attorney-in-Fact. Employee shall disclose promptly to the Company all Developments during the term of Employee's employment with the Company. Any information required to be disclosed under this Section 5.2 that has not yet been disclosed by the Employee to the Company at the time of the termination of the Employee's employment with the Company, without regard to when or for what reason, if any, such employment shall terminate, shall be disclosed to the Company in writing, or in such form and manner as the Company may reasonably require, within 10 days of the termination of the Employee's employment with the Company. Employee hereby irrevocably appoints the Company (or such Schrödinger Company designated by the Company), and the Company's duly authorized officers and agents, as Employee's agent and attorney-in-fact to act for and on behalf of Employee in filing all patent applications, applications for copyright protection and registration amendments, renewals, and all other appropriate documents in any way related to the Developments. Employee agrees to

assist the Company (or such Schrödinger Company designated by the Company) in any way such Schrödinger Company deems necessary or appropriate (at such Schrödinger Company's expense) from time to time to apply for, obtain and enforce patents on, and to apply for, obtain, and enforce copyright protection and registration of, the Developments in any and all countries. To that end, Employee shall (at the request of one or more Schrödinger Companies), without limitation, testify in any suit or other proceeding involving any of the Developments, execute all documents which the relevant Schrödinger Company reasonably determines to be necessary or convenient for use in applying for and obtaining patents or copyright protection and registration thereon and enforcing the same, and execute all necessary assignments thereof to the Company (or such Schrödinger Company designated by the Company).

5.3 California Labor Code Section 2870(a). For the avoidance of doubt, Developments do not include any invention covered by California Labor Code Section 2870(a). Section 2870(a) provides:

ANY PROVISION IN AN EMPLOYMENT AGREEMENT WHICH PROVIDES THAT AN EMPLOYEE SHALL ASSIGN, OR OFFER TO ASSIGN, ANY OF HIS OR HER RIGHTS IN AN INVENTION TO HIS OR HER EMPLOYER SHALL NOT APPLY TO AN INVENTION THAT THE EMPLOYEE DEVELOPED ENTIRELY ON HIS OR HER OWN TIME WITHOUT USING THE EMPLOYER'S EQUIPMENT, SUPPLIES, FACILITIES, OR TRADE SECRET INFORMATION EXCEPT FOR THOSE INVENTIONS THAT EITHER:

6.2 Non-Solicitation of Customers. Vendors or Business Partners. During the term of Employee's employment and for a period of one (1) year thereafter, Employee shall not, directly or indirectly, solicit or encourage any customer, prospective customer, vendor, strategic partner or business associate of a Schrödinger Company to cease doing business with a Schrödinger Company, reduce its relationship with a Schrödinger Company, or refrain from establishing or expanding a relationship with a Schrödinger Company. For the purposes of this section, "prospective customer" shall mean any individual, business, firm or organization whom Employee or a Schrödinger Company has contacted during the term of the Employee's employment or who has been made known to Employee by a Schrödinger Company for the purpose of soliciting business.

6.3 Non-Solicitation of Employees. During the term of Employee's employment and for a period one (1) year thereafter, Employee shall not directly or indirectly, without the prior written consent of the Company, (a) solicit or induce any employee of a Schrödinger Company or the D.

Shaw Group) to cease his employment or retention by a Schrödinger Company or the D. E. Shaw Group, or (b) hire, retain, employ, or engage for any purpose any employee of a Schrödinger Company or the D. E. Shaw Group.
